Hybrid vehicles offer the best of both worlds: gas efficiency and electric innovation. But when your hybrid car won’t start, many drivers ask the same question: Can you jumpstart a hybrid car like a regular vehicle?
The short answer is yes, you can jumpstart a hybrid—but with some important differences and precautions. This guide will walk you through how hybrid batteries work, when and how to jumpstart one safely, and what to avoid to prevent costly damage.
How Hybrid Cars Are Different from Traditional Cars
Hybrid vehicles use two batteries:
- High-voltage hybrid battery (used to power the electric motor)
- 12-volt auxiliary battery (used to start the vehicle and power accessories)
In most cases, it’s the 12-volt battery that dies, not the large hybrid battery. This smaller battery is very similar to the one found in conventional gas-powered cars—and that’s the one you’ll be jumpstarting.
When Can You Jumpstart a Hybrid?
You can jumpstart a hybrid car if:
- The vehicle won’t start, but lights and dashboard might still flicker
- You hear clicking or no sound when pressing the start button
- The 12-volt battery is drained, not the main hybrid battery
Important: If your vehicle displays a high-voltage battery fault or hybrid system error, don’t attempt to jumpstart it. Call roadside assistance or your dealership.
How to Safely Jumpstart a Hybrid Car (Step-by-Step)
What You’ll Need:
- Jumper cables (or a portable jump starter)
- Another car with a charged 12-volt battery (if not using a jump box)
- Safety gloves and goggles (optional but recommended)
Step 1: Locate the 12-Volt Battery
The 12V battery in hybrids is often in the trunk, cargo area, or under a seat—not always under the hood. Refer to your owner’s manual for the exact location.
Some hybrids also have a designated jumpstart terminal under the hood that connects to the 12V system.
Step 2: Connect the Jumper Cables
- Red clamp to dead battery (+) terminal
- Red clamp to good battery (+) terminal
- Black clamp to good battery (–) terminal
- Black clamp to a metal ground (not the battery!) on the dead vehicle—like a bolt or bracket
Never connect the negative cable directly to the dead battery. It can cause sparks near the battery and create a fire hazard.
Step 3: Start the Donor Vehicle
Let the donor vehicle run for 3–5 minutes to send some charge into the dead 12V battery.
Step 4: Start the Hybrid
Press the start button (with your foot on the brake). You may not hear an engine noise right away—most hybrids start silently in EV mode. Look for:
- Dashboard lights turning on
- Ready or “ON” indicator
- Power restored to systems
Step 5: Disconnect the Cables (in reverse order)
- Black from grounded metal
- Black from donor battery
- Red from donor battery
- Red from dead battery
Let your hybrid run for at least 20–30 minutes or take a drive to recharge the 12-volt system.
Can You Use a Portable Jump Starter on a Hybrid?
Yes—many portable lithium jump starters are compatible with hybrid cars. Just make sure it supports 12-volt systems and follow the same connection steps.
Tip: Some hybrids, like the Toyota Prius, even have special jump points under the hood for this purpose.
When You Should NOT Jumpstart a Hybrid
- If the high-voltage system is damaged (usually indicated by warning lights)
- If the car was recently in an accident
- If you smell burning or see smoke near the battery
- If you’re unsure which battery is dead—consult a professional
Jumpstarting the wrong component—like trying to access the high-voltage hybrid battery—can cause severe injury or permanent vehicle damage.
What to Do If the Jump Doesn’t Work
- Double-check your cable connections
- Make sure the donor vehicle’s battery is strong enough
- Wait a few more minutes before trying again
- If the car still won’t start, call roadside assistance or your dealership
Final Thoughts: Yes, You Can Jumpstart a Hybrid—Carefully
While hybrids have more complex systems, jumpstarting them is often just as easy as a regular car—if it’s the 12V battery that’s dead. Always refer to your owner’s manual and take proper precautions when handling electrical systems.
