Understanding Your Vehicle’s Warning Lights

Dash light on?

You want your Christmas tree all lit up, but not your dash. Below is your guide to what each light means.

Check Engine Light:

This light illuminates when your car is in the Run position but should turn off when the car is started. If it doesn’t, then the computer is telling you that you may have a problem affecting fuel economy, emissions, or driveability. You can still drive with the light on, but you should visit us sooner rather than later.

Flashing Check Engine Light:

If your light is flashing after you start the vehicle, then the computer is telling you catalytic converter damage is imminent, and you may experience a loss of power or irreversible damage.

Tire Pressure Warning Light:
This light illuminates when the sensor that is built into each of your wheels senses that there is low pressure in the tire. Low pressure could be caused by a bad seal at the rim, metal in the tire, or a cold snap (cold air exerts less pressure than hot air). Visit us soon so you don’t damage your tire or cause a blowout.

Flashing Tire Pressure Light:
A flashing tire pressure light indicates that your system needs to be serviced. This may illuminate because a sensor is broken or the whole system is giving false readings. Don’t wait too long to fix this because you’re flying blind about the pressure in your tires. Driving on a tire without enough air in it can ruin it.

Oil Change Required Light:
This light will illuminate when your vehicle is ready to be serviced and it’s time to have the old oil drained and fresh oil put into your motor. Ignoring this light for long enough can cause damage to your motor down the road. Note: different vehicles use different indicator lights.

Oil Pressure Warning Light:
This light indicates your motor is operating without sufficient lubrication. Driving any distance with this light on can do EXTREME damage to your engine and turn a minor problem into a major one.

Charging system Light:
This light indicates that your vehicle’s charging system is not working properly. Drive with this light on and you can end up stranded on the side of the road with a dead battery.

Windshield Washer Fluid Low Light:
A friendly indicator to let you know that your washer fluid is running low and needs to be filled.

Coolant Temperature Warning light:
This light means your coolant system is running low on coolant (antifreeze). This means your engine is also running at a higher than normal temperature which can lead to internal engine problems. You might be able to crawl the vehicle to the dealership but it is recommended you don’t drive with the light on to keep from damaging your motor.

Transmission Temperature Warning Light:
This light indicates your vehicle’s transmission is running at a higher than normal operating temperature. Ignoring this light can cause your transmission to overheat and damage internal parts.

Brake System Warning Light:
This light indicates a problem with the vehicle’s braking system or that your parking brake is on. Brake failure is serious so visit us ASAP.

ABS Fault Light:
This light means there is a problem with your vehicle’s anti-lock braking system. Visit us soon.

Traction Control:
This light illuminates when your vehicle’s anti-skid or traction control system is active. This light is to tell you that your vehicle is experiencing a problem with low traction, such as driving through rain, snow or ice. When this light appears it’s a good idea to slow down under slippery conditions. If it remains illuminated constantly, visit us.

ESP Fault:
Some vehicles are equipped with stability control or an ESP system. This system takes control of your vehicle’s braking and throttle when your vehicle looses control to safely get your vehicle going straight again.

Airbag Fault:
This light will usually flash or come on for a few seconds when the vehicle is started but this is normal. If the light stays on for more than a few seconds or stays on, then there is a fault in the airbag system. Service it soon, because all or part of your airbag system will not operate in a crash.

Cruise Control Active:
This light illuminates when your vehicle’s cruise control is active. This is when the car is set for a selected speed and will you the brakes and throttle to hold the vehicle at that speed while driving on the highway.

Contact Service Department with any Questions

“Found the truck I had been searching for online. I filled out a inquiry and my salesman called me first thing in the morning. I drove to the dealer, test drove the truck, negotiated trade and price and drove away that evening with my truck. I was a stress free process. I highly recommend Planet Chrysler Jeep Dodge in Franklin.”
