2010 Infinity G37 Jump Starting Instructions A Quick Guide

Jump-starting your 2010 Infiniti G37 safely starts with locating the hidden positive terminal under the hood, not the battery itself, to avoid damage to sensitive electronics. Always connect the red clamp to this terminal and the black clamp to an unpainted engine ground, then power up the donor vehicle before starting your G37 to prevent voltage spikes. This quick, precise method ensures a reliable start without risking costly electrical system harm.

Key Takeaways

• Locate the battery: Find the battery under the rear seat for safe jump starting.
• Use quality cables: Always use heavy-duty jumper cables to avoid damage.
• Connect red first: Attach the positive (red) clamp to the dead battery first.
• Ground the black clamp: Secure the negative (black) to an unpainted metal surface.
• Start the donor car: Let the working car run 3-5 minutes before starting.
• Remove cables safely: Disconnect in reverse order after successful jump start.

Why Jump Starting Your 2010 Infinity G37 Matters

Let’s face it—there’s nothing more frustrating than hopping into your 2010 Infinity G37 and hearing that dreaded silence when you turn the key. No crank, no click, just… nothing. You’ve probably been there: the battery’s dead, and you’re stuck. Maybe you left a light on, or the cold weather drained it overnight. Whatever the reason, a dead battery is a common car problem—but it doesn’t have to ruin your day. That’s where knowing how to jump start your Infinity G37 comes in handy.

Jump starting your car isn’t just about saving time or avoiding a tow. It’s about being prepared, especially when you’re in a hurry or far from help. I remember one winter morning when my G37 wouldn’t start after a snowstorm. I was late for work, and my jumper cables were buried under a foot of snow. After a frantic 10-minute dig, I managed to get them out—only to realize I’d never actually jump-started a car before. It was a humbling moment, but also a turning point. Since then, I’ve made it a point to understand every step, from locating the battery to safely disconnecting cables. And now, I’m sharing that knowledge with you.

Understanding the 2010 Infinity G37 Battery System

Where’s the Battery Located?

One of the first things you’ll notice about the 2010 Infinity G37 is that the battery isn’t where you might expect. Unlike many sedans with batteries under the hood near the front grille, the G37 hides its battery in the trunk—specifically, under the floor panel on the right side (passenger side). This design choice helps with weight distribution and keeps the engine bay cleaner, but it can be a surprise for first-time jump starters.

To access the battery, you’ll need to:

• Open the trunk.
• Lift the floor mat and remove the plastic cover.
• Unscrew the small retaining bracket (if present).
• Pull back the protective cover to expose the battery terminals.

Pro tip: Keep a small flashlight and a flathead screwdriver in your trunk tool kit. You’ll often need them to remove the cover quickly, especially in low light or bad weather.

Battery Specifications and Health

The stock battery in the 2010 G37 is typically a Group 35, 12V lead-acid battery with around 650-700 cold-cranking amps (CCA). This is more than enough for most driving conditions, but extreme heat or cold can reduce its effectiveness. Over time, sulfation (a buildup of lead sulfate crystals) and corrosion on the terminals can also weaken performance.

Signs your battery might be failing:

• Slow engine crank (takes longer to start).
• Dim headlights or interior lights.
• Frequent need for jump starts.
• Battery warning light on the dashboard.

I once ignored these signs for weeks, thinking the battery would “just hold on.” Then one morning, it died in a parking garage with no help in sight. Lesson learned: don’t wait for a complete failure. Test your battery every 6 months, especially before winter.

Why the Trunk Location Affects Jump Starting

Because the battery is in the trunk, you can’t just connect jumper cables directly to the terminals like in most cars. Instead, Infinity provides a jump starting terminal under the hood. This is a small, red-capped positive (+) post located near the fuse box on the driver’s side. It’s connected via a heavy-duty cable directly to the battery, so it’s safe to use for jump starting.

The negative (-) cable, however, should not be connected to the battery’s negative terminal in the trunk. Instead, attach it to a grounded metal surface under the hood—like a bolt or bracket on the engine block. This prevents sparks near the battery, reducing the risk of explosion from hydrogen gas buildup.

Tools and Safety Gear You’ll Need

Essential Equipment Checklist

Before you attempt to jump start your 2010 Infinity G37, make sure you have the right tools. Here’s what you need:

• Jumper cables: At least 10-12 feet long with thick, 4-6 gauge wires. Thin cables won’t deliver enough power.
• Another running vehicle: A friend’s car, a neighbor’s, or a roadside assistance vehicle.
• Flashlight: For visibility in dark or dimly lit areas.
• Gloves and safety glasses: Protect your hands and eyes from battery acid and sparks.
• Owner’s manual: For quick reference on terminal locations and warnings.
• Small flathead screwdriver: To remove the trunk battery cover if stuck.

I keep a jump starter kit in my G37’s trunk: cables, gloves, a flashlight, and a printed copy of the jump start diagram. It’s saved me more than once.

Why Safety Matters

Batteries contain sulfuric acid and produce flammable hydrogen gas. A single spark near the battery can ignite the gas, causing an explosion. That’s why proper grounding and cable order are critical.

Safety rules to follow:

• Never smoke or use open flames near the battery.
• Keep metal tools away from the terminals to avoid short circuits.
• Wear gloves to protect against acid burns.
• Work in a well-ventilated area—especially in enclosed spaces like garages.
• Double-check cable connections before starting the donor car.

One time, I saw a guy connect the negative cable directly to the battery terminal in the trunk. The spark scared everyone nearby, and it could’ve been much worse. Always use the under-hood grounding point.

Optional but Helpful Add-Ons

While not required, these tools make the process easier and safer:

• Portable jump starter (lithium battery pack): No need for another car. Just connect and go. I use one in emergencies—it’s lightweight and fits in my glove box.
• Battery terminal cleaner: Helps remove corrosion and improve connections.
• Multimeter: Lets you check battery voltage before and after jump starting.

After my first jump start with cables, I bought a portable jump starter. It’s been a game-changer, especially when I’m alone or in a remote area.

Step-by-Step Jump Starting Instructions

Step 1: Prepare the Vehicles

Park the donor car (the one with the good battery) close to your G37—but don’t let them touch. Position them so the jumper cables can reach from one engine bay to the other. Turn off both vehicles, set the parking brakes, and put them in Park (automatic) or Neutral (manual).

Open the hoods of both cars. Locate the jump starting terminal on your G37 (driver’s side, near the fuse box, red cap). On the donor car, find the battery terminals: positive (+) and negative (-).

Tip: If the donor car has a battery in the trunk too (like some luxury models), use the same method—connect to the under-hood positive terminal and a grounded metal point.

Step 2: Connect the Jumper Cables (Correct Order!)

This is where many people mess up. The order of connections is crucial for safety and success.

1. Connect the red (+) cable to the G37’s jump starting terminal (red cap under the hood).
2. Connect the other end of the red cable to the donor car’s positive (+) battery terminal.
3. Connect the black (-) cable to the donor car’s negative (-) terminal.
4. Connect the other end of the black cable to a grounded metal surface on the G37’s engine block (not the battery). Look for a bolt, bracket, or unpainted metal part.

Never connect the black cable to the G37’s battery terminal in the trunk. This creates a spark near the battery and risks explosion.

I once saw a guy connect the black cable to the battery terminal. The spark made a loud pop, and he jumped back. It was a close call. Always ground under the hood.

Step 3: Start the Donor Car and Let It Run

Start the donor car’s engine and let it run for 2-3 minutes at idle. This allows the good battery to charge your G37’s battery slightly. Avoid revving the engine—just let it idle smoothly.

During this time, you might notice:

• The G37’s dashboard lights flicker or turn on.
• The radio or clock powers up.
• The engine cranks slightly when you try to start it.

These are good signs—your battery is getting juice.

Step 4: Attempt to Start Your G37

After 2-3 minutes, try starting your Infinity G37. Turn the key and listen. If it cranks slowly, wait another minute and try again. If it starts, great! Let it run for at least 5 minutes to build up charge.

If it doesn’t start:

• Check all cable connections. Are they tight and clean?
• Ensure the black cable is grounded, not on the battery.
• Let the donor car run for 5 more minutes, then retry.

Pro tip: If it still won’t start, the battery might be too far gone. Consider calling for a replacement or using a portable jump starter with higher cranking power.

Step 5: Disconnect Cables in Reverse Order

Once your G37 is running, disconnect the cables in the reverse order:

1. Remove the black cable from the G37’s engine block (ground).
2. Remove the black cable from the donor car’s negative terminal.
3. Remove the red cable from the donor car’s positive terminal.
4. Remove the red cable from the G37’s jump starting terminal.

Coil the cables neatly and store them. Close the hoods of both cars.

Post-Jump Care and Battery Health

Let the Engine Run and Drive

After jump starting, don’t turn off the engine. Let it run for at least 15-20 minutes to allow the alternator to recharge the battery. Better yet, take a 20-30 minute drive—this gives the alternator more time to work and helps clear any system warnings.

During this drive:

• Check for dashboard warning lights (especially battery or alternator).
• Listen for unusual sounds from the engine.
• Test the headlights and electronics to ensure they’re working.

I once jumped my G37 and drove straight into a meeting. I didn’t realize the battery wasn’t holding a charge until it died again in the parking lot. A short drive isn’t enough—go for at least 20 minutes.

When to Replace the Battery

A jump start is a temporary fix. If your battery fails frequently, it’s time to replace it. Most car batteries last 3-5 years. The 2010 G37 is now over a decade old, so even with good care, the original battery has likely reached the end of its life.

Signs you need a new battery:

• More than 3 jump starts in a year.
• Battery voltage below 12.4V when the car is off (use a multimeter).
• Swollen or leaking battery case.
• Corrosion that won’t clean off.

When replacing, choose a Group 35 battery with at least 650 CCA. Brands like Optima, DieHard, and ACDelco are reliable. Some owners upgrade to AGM (Absorbent Glass Mat) batteries for better cold-weather performance and longer life.

Preventing Future Battery Issues

To avoid dead batteries in the future:

• Turn off all lights and electronics when exiting. Use the “door chime” feature to remind you.
• Use a battery tender if the car sits for weeks. These maintain charge without overcharging.
• Clean terminals every 6 months. Use baking soda and water to remove corrosion.
• Park in a garage when possible. Extreme heat or cold accelerates battery drain.

I now keep a battery tender in my garage and plug it in whenever the G37 won’t be driven for more than a week. It’s a small habit that saves big headaches.

Common Mistakes and Troubleshooting

Top 5 Jump Start Errors (and How to Avoid Them)

Even experienced drivers make mistakes. Here are the most common ones—and how to fix them:

1. Connecting black cable to the battery terminal: Always ground under the hood.
2. Using old or thin jumper cables: Upgrade to 4-gauge cables for reliable power.
3. Starting the dead car too soon: Wait at least 2-3 minutes after connecting.
4. Forgetting to turn off accessories: Turn off lights, radio, and AC before jump starting.
5. Disconnecting cables while the engine is running: Always turn off the G37 first.

One winter, I forgot to turn off the headlights before jump starting. The surge from the cables caused a fuse to blow. It cost me $20 and 20 minutes at the auto parts store. Lesson learned: check everything before connecting.

What If the Car Still Won’t Start?

If your G37 doesn’t start after a proper jump, the issue might not be the battery. Consider:

• Starter motor failure: You’ll hear a click but no crank.
• Alternator problems: Battery dies quickly after jump starting.
• Faulty ignition switch: Dashboard lights up, but no crank.
• Bad ground connections: Check all engine and chassis grounds.

Use a multimeter to test battery voltage while the engine is running. It should read 13.8-14.7V. If it’s below 13V, the alternator isn’t charging.
