When your car won't start all of a sudden, particularly in the middle of a hectic day, it could be frustrating, more so if you own an automatic. Amongst the most frequent reasons for this is a flat battery. While manual car owners may try to push-start in such instances, automatic car owners cannot.
We have created a guide for you to learn how to start an automatic car when the battery is low. From jump-starting techniques to necessary precautions and long-term remedies, we have it all that you might need to get moving quickly and safely again. You will find the solutions here to be simple and effective, whether you are a new car owner or experiencing the problem for the first time.
Why Your Automatic Car Won’t Start: The Battery Factor
Before diving into solutions, it’s important to know why an automatic car won’t start when the battery is dead.
Newer automatic vehicles contain more electronics, push-button starting, infotainment, auto climate control, and sophisticated sensors. These components rely a great deal on battery power. If your battery drains, the starter motor, electronic ignition, and even central locking may fail to operate.
As opposed to manual vehicles, you cannot push-start an automatic vehicle because of the transmission design. Therefore, it is important to know what to do in such a situation.
Signs Your Battery is Dead in an Automatic Car
Here’s how to tell if your car won’t start due to battery issues:
-
The engine won’t turn on when you push the start button
-
Dashboard lights are dim or flickering
-
No sound or click when turning the key or pushing the button
-
Central locking is not working
-
Headlights or cabin lights are unusually dim
-
A battery warning light is showing on the dashboard
If you spot any of these, it’s very likely that the battery is drained or dead.
How to Start Automatic Car When Battery is Down
Let’s get straight to the point. If your automatic car battery is dead, here are the most effective and safe methods to start it again:
1. Jump Start Using Jumper Cables (With Another Car)
This is the most common way to start a dead car battery.
You’ll need:
-
Jumper cables
-
Another car with a working battery (same voltage: 12V for most cars)
-
A safe place to park both vehicles close together
Step-by-step:
-
Turn off both vehicles.
-
Connect one red clamp to the positive (+) terminal of the dead battery.
-
Connect the other red clamp to the positive terminal of the good battery.
-
Connect the black clamp to the negative (–) terminal of the good battery.
-
Finally, connect the other black clamp to a metal part of the dead car’s engine block (not the battery).
-
Start the working car and let it idle for a few minutes.
-
Try starting the dead car. If successful, let it run for at least 15 minutes to recharge.
-
Remove cables in reverse order.
This method is widely used and works most times if your automatic car battery is dead but not completely worn out.
2. Use a Portable Jump Starter
If you’re alone and don’t have another vehicle around, a portable jump starter can be a lifesaver.
These small devices are battery-powered and designed to jump-start your car without external help.
How to use it:
-
Connect the positive and negative clamps to your car battery terminals (as mentioned above)
-
Turn on the jump starter
-
Start the car
This method is safe, quick, and ideal for emergencies.
3. Can You Push-Start an Automatic Car?
No. Unlike manual cars, you cannot push-start an automatic car. The transmission system in automatics doesn't allow this method due to the lack of a physical clutch and gear synchronisation.
Trying to push-start an automatic car could damage the transmission and other components. Always use jump-start methods instead.
4. What Not to Do
Avoid these mistakes when trying to fix a dead battery:
-
Don’t keep trying to crank the engine; you could drain the battery further.
-
Don’t connect jumper cables incorrectly; wrong polarity can fry your car’s electronics.
-
Don’t use old or damaged jumper cables; they can be unsafe.
-
Don’t ignore warning signs; a repeatedly dead battery might need replacement.
Stuck Without Help? Here’s What You Can Do
If you're alone, without another car or jump starter, here's what you can try:
-
Call a friend or neighbor with jumper cables
-
Use a roadside assistance app (like Allianz, or your car’s own brand service)
-
Look for help at fuel stations; many have service personnel or mechanics who can assist
Roadside Assistance Services in India
Most car brands in India offer roadside assistance packages, even for older vehicles.
Common services:
-
Battery jump-start
-
Battery replacement
-
Emergency towing
-
Fuel delivery
Popular providers:
-
Maruti Suzuki On-Road Service (MOS)
-
Hyundai RSA
-
Honda RSA
-
Mahindra With You Hamesha
-
TVS Auto Assist
These are invaluable if your car battery is dead in India, especially in remote areas.
What About Manual Cars?
Manual cars offer more flexibility in this situation. If the battery is weak but not completely dead, you can push-start it in 2nd gear.
Push-start steps (manual cars only):
-
Switch ignition to ON
-
Put the car in 2nd gear, clutch pressed
-
Ask someone to push the car
-
When moving, release the clutch quickly while giving light throttle
This may jerk the engine to life. However, avoid frequent push-starting, as it stresses the battery and starter motor.
Tips to Prevent Battery Failure in Automatic Cars
Don’t want to deal with a dead battery again? Follow these simple tips:
-
Drive your car regularly, and avoid letting it sit idle for long
-
Don’t leave headlights or interior lights on when parked
-
Avoid short trips, and only give your battery time to recharge
-
Get the battery checked during routine service
-
Clean terminals to prevent corrosion
-
Use a battery trickle charger if you won’t drive for weeks
When to Replace Your Car Battery
Batteries don’t last forever. Here’s how to know it’s time for a new one:
-
The battery is older than 3 - 4 years
-
Frequent jump starts required
-
The engine cranks slowly
-
Swollen battery casing
-
The battery warning light stays on
Regular servicing can help detect these early.
A dead battery in an automatic car can be frustrating, but it’s fixable. Knowing how to start automatic car when battery is down can save you time, stress, and money. Whether it’s using jumper cables, a portable starter, or calling roadside assistance, now you’re prepared for the unexpected.
Make sure you check your battery regularly, drive your car often, and invest in a portable jump starter for emergencies. Most importantly, avoid risky hacks like push-starting an automatic car.
