Getting stranded with a dead battery in your 2018 Jeep Compass can be stressful, especially if you’re in a hurry or in an unfamiliar place. Luckily, jumping a car is a simple process if you know the right steps. This guide will walk you through how to safely jump-start your Jeep Compass, which tools you need, and what precautions to take. Even if you’ve never done this before, you’ll find clear instructions and helpful tips to get you back on the road quickly.
What You’ll Need To Jump A Jeep Compass 2018
Before you start, make sure you have the right tools. You will need:
- Jumper cables (at least 10 feet long)
- Another car with a fully charged 12-volt battery
- Safety gloves (optional but recommended)
- Safety glasses (for extra protection)
If you don’t have another vehicle, you can use a portable jump starter. However, the steps here will focus on using another car, which is the most common method.
Safety Precautions Before You Begin
Jump-starting a car is safe when done correctly, but there are risks if you rush or skip steps. Follow these important safety tips:
- Turn off both vehicles and set the parking brakes.
- Remove any metal jewelry to avoid accidental shocks.
- Keep cables away from moving parts like fans or belts.
- Don’t let the metal clamps touch each other during the process.
A surprising fact: Modern cars, including the 2018 Jeep Compass, have more electronics than older models. Connecting cables in the wrong order can damage sensitive systems. Always double-check the instructions before you start.
Step-by-step Guide: Jump-starting Your Jeep Compass
Follow these steps to safely jump your 2018 Jeep Compass:
1. Position The Vehicles
Park the working car close to your Jeep Compass, but make sure the vehicles are not touching. The batteries should be as close as possible for the cables to reach.
2. Open The Hoods
Locate the hood release inside both vehicles. Secure the hoods with the prop rods.
3. Find The Battery Terminals
On the Jeep Compass, the battery is usually in the front engine bay. Identify the positive (+, red) and negative (−, black) terminals.
4. Connect The Jumper Cables
Attach the clamps in this order:
- Red clamp to the positive terminal of the dead battery (Jeep).
- Red clamp to the positive terminal of the working battery.
- Black clamp to the negative terminal of the working battery.
- Black clamp to an unpainted metal surface (engine block or frame) on the Jeep Compass, away from the battery.
This order prevents sparks near the battery, which can be dangerous.
5. Start The Working Car
Let it run for 2–3 minutes to send power to the dead battery.
6. Start Your Jeep Compass
Try to start your Jeep. If it doesn’t start after 10 seconds, wait another minute and try again. Don’t crank the engine for too long—this can damage the starter.
7. Remove The Cables Carefully
Remove the cables in reverse order:
- Black clamp from the Jeep’s metal surface
- Black clamp from the working car
- Red clamp from the working car
- Red clamp from the Jeep Compass
Don’t let the clamps touch each other while removing them.
8. Let Your Jeep Run
Keep your Jeep Compass running for at least 15–20 minutes to help recharge the battery.
Comparison: Portable Jump Starter Vs Jumper Cables
For many drivers, a portable jump starter is an alternative to jumper cables. Here is a quick comparison:
| Feature | Jumper Cables | Portable Jump Starter |
|---|---|---|
| Requires another vehicle | Yes | No |
| Ease of use | Moderate | Easy |
| Cost | Low | Medium–High |
| Portability | Bulky | Compact |
A portable jump starter is great for emergencies when no one else is around. However, jumper cables are cheaper and never need to be recharged.
Common Mistakes When Jump-starting
Many people make simple but costly errors when jumping a car. Here are the most common mistakes and how to avoid them:
- Incorrect cable order: Always follow the sequence listed above.
- Poor contact with terminals: Make sure clamps are tightly attached to clean, uncorroded metal.
- Jumping a damaged battery: Swollen or leaking batteries can explode. If you see this, don’t attempt a jump—call for help.
- Not running the engine after jump-starting: If you drive off too soon, your battery might die again.
Troubleshooting: If Your Jeep Compass Won’t Start
If your Jeep Compass still won’t start after following all steps, consider these possibilities:
| Possible Issue | What to Do |
|---|---|
| Loose or corroded cables | Check and clean the terminals, reconnect and try again |
| Completely dead battery | Battery may need to be replaced |
| Faulty starter or alternator | Seek professional help |
| Blown fuse | Check fuse box and replace if needed |
Don’t overlook the alternator—if your Jeep dies again soon after starting, the alternator might not be charging the battery.
Tips To Prevent A Dead Battery
Taking a few simple steps can help you avoid battery problems in the future:
- Turn off headlights and interior lights when parking
- Avoid running electronics while the engine is off
- Drive your Jeep regularly, especially in cold weather
- Get your battery checked every year, especially after three years of use
Most car batteries last 3–5 years, but extreme heat or cold can shorten this lifespan.
