Jeep Wrangler Dashboard Lights Guide: Know What They Mean

Jeep Wrangler is a rough and tough off-road Jeep with outstanding performance on rough terrains. However, knowing about the Jeep Wrangler dashboard light guide is essential. Thus you can ensure that everything in your vehicle is running smoothly.

Start with the owner’s manual guide. All indicators are no warning signs. Instead, some, like ACC indicators, tell you what the car is doing now.

However, you must learn the warning signs to tackle any situation while roaming the road. Master warning lights, red dashboard lights, and low fuel warning lights are the most common warning signs in the Jeep Wrangler dashboard.

Warning lights direct you effectively while fixing the problem in your Jeep Wrangler. The limited knowledge of dashboard lights can endanger your life.

Master Warning Light

While driving, you see an exclamatory light confined in a triangle in the dashboard. As you do not know its meaning, so you can google it. But did you find an answer? Well, finding an absolute solution for this mark isn’t easy!

The sign you saw earlier was a master warning light. With this, your Jeep is trying to tell you that there is some problem with the advanced systems.

For example, the brake fluid is low, or the battery is malfunctioning. Thus, there is no exact answer for what the master warning light is illuminated.

What Can You Do?

You have to troubleshoot the warning as soon as possible. Go to the professionals if you are not a good DIYer.

Ignoring the master warning light can seriously harm your Jeep. So, do not waste your time. Fix the problem sooner to prevent further damage to the Jeep.

Lightning Bolt Warning Light

The lightning bolt on your Jeep’s dashboard indicates that your ETC (Electronic Throttle Control) has faced some issues.

ETC controls how much air and fuel should enter your engine. Thus, the failure of this system will flash the lightning bolt warning light. So, there must be some problem with your engine’s air and fuel intake.

Different scenarios can raise the ETC problem, like a dirty throttle body, malfunctioning throttle position sensor, etc.

What Can You Do?

You may drive with an ETC Warning Light. However, this may cause engine failure, leading to severe accidents.

Clean the throttle body. If it does not work, contact a professional. Mechanics may charge you from $100 – $300 for malfunctioning or dirty throttle.

Again, if the problem is in the powertrain control module, you may have to spare a good amount of money.

Red Dashboard Lights

We use red lights when attention is needed. The Jeep Wrangler dashboard follows the same rule. Whenever you see the red dashboard light pop off, you will know there is some severe problem.

The red lights represent problems with the braking system, transmission, or engine. For example, the oil warning lights, brake trouble indicators, or transmission fault indicators are red.

Moreover, some typical indicators are also marked with a red light. Seat belt reminders or security indicators fall into this category.

What Can You Do?

Check what the sign means and search for possible problems. You can start with fluid levels like coolant, brake fluid, or oil. Again, do not forget to check the wiring and the battery cables.

The owner’s manual may come in handy while looking for problems because the meaning of the signs may differ depending on the model and year of the Jeep Wrangler.

If the problem is not easy, you must go to a professional.

Adaptive Cruise Control System Warning Light

Driving on the highway feels more comfortable with an Adaptive Cruise Control (ACC) System. This smart system reduces the likelihood of crushes on the road.

You might have noticed that there are multiple ACC indicators. These symbols indicate whether the speed is being limited. But we will not focus on them today. Instead, we will discuss the ACC warning light.

ACC warning light tells us if there are issues with the ACC system. The symbol contains an exclamation mark illustrating a road or speedometer.

There are more common reasons for the problem, like something blocking the ACC camera or radar. However, you might face a more complex situation where the whole system is malfunctioning.

What Can You Do?

First, look for something that is blocking the camera or radar. If you find anything, clean it. However, if that is not the case, turn off your ACC system.

A malfunctioning ACC system might increase the chances of accidents. So, do not use it before fixing the problem.

Engine Oil Pressure Warning Light

This might be the fascinating warning light that features an Aladdin’s lamp. But what does it mean?

As you can see, there is a drop of oil falling from the oil can. This indicates that your oil pressure is getting low. The low oil pressure will reduce the engine’s rotation per minute (RPM). It can also seriously damage the engine if not fixed immediately.

What Can You Do?

Check the oil level in the machine. If the oil level is down, get your engine some oil. Otherwise, the indicator means your engine is malfunctioning, resulting in low oil pressure.

In the latter case, you must contact a professional to fix the problem. Do not dare to drive with this indicator on.

Temperature Warning Light

An overheating thermometer exerts some intense heat – that’s what the temperature warning light looks like. This warning indicates an overheating engine.

Driving in hot weather and getting your engine overworked are common reasons for an illuminating temperature warning. Again, a malfunctioning cooling system can cause the sign to illuminate too.

What Can You Do?

The temperature warning light comes up as an early warning. So you may drive for a mile and check if the indicator is gone.

Suppose it does not immediately pull over your car and shut your engine off. Wait some time to cool down your machine.

However, contact a professional if the indicator does not go away permanently or keeps coming back.

Low Fuel Warning Light

This is the most common sign of all. The low fuel warning indicator pops up whenever you are low on fuel.

However,  getting the signal with an exclamation mark is where the problem begins. It means that your fuel gauge is not working. This often happens when the fuel sensor system fails.

What Can You Do?

With a low fuel indicator, fill up your fuel tank. However, if the sensors fail, you must fix them immediately.
