Jaguar Warning lights

Make sure you familiarise yourself with the most important warning lights on your Jaguar. If you are curious about what all of the amber, yellow, blue, or green lights can mean, be sure to check out our warning light guide. Alternately check your Jaguar owner’s manual for a full breakdown of the Jaguar dashboard warning symbols and their meanings.

Jaguar Red Warning Lights

Battery

When you turn on your vehicle’s ignition, the 12v battery charge light should come on to indicate that the bulb is working, and once the engine has started this will stop. However, if the light stays illuminated or it comes on suddenly while you’re driving, then there could be a fault with the battery. 

Low oil pressure

If your low oil pressure indicator illuminates or begin to flash, stop driving as soon as you safely can, making sure you turn off the engine completely after you’ve stopped.

Inspect your oil level and top up if required. 

Triangle critical warning

Your triangle critical warning light will illuminate when there is an important message displayed on the instrument panel and should be investigated as soon as possible.

Engine temperature

If the engine’s temperature is too high, the engine temperature warning light will come on. This will be accompanied by a warning message on the instrument panel. If this happens while driving, stop the vehicle when it is safe to do so. You can then report the fault or get some advice.

Jaguar Amber Warning Lights

Check engine

The check engine light will illuminate after you’ve switched on the ignition and should go off when the engine starts. If it stays lit while driving, then there could be an issue with the emissions. Your vehicle will still be safe to drive, but you should book in a service as soon as possible.

You might experience reduced performance from your Jaguar, which will be in limp-home mode to protect the vehicle from further damage. 

If you notice the light is flashing while driving or when the engine running, slow down and get the engine looked at as soon as possible.

DEF filter warning light

The Diesel Exhaust Fluid (DEF) will appear amber if the DEF level is running low. It can also light up if the wrong fuel has been added, or due to a system fault. 

Check your instrument panel for an accompanying warning.

Dynamic Stability Control

The Dynamic Stability Control (DSC) light will flash when the system is triggered. It will stay lit if there is a system fault, and the instrument panel will have an accompanying warning message. You will still be able to drive with the light on, but you won’t benefit from DSC assistance, so take extra care when driving. 

If there is a fault with the system, it remains illuminated and the instrument panel displays a warning message. You can still drive, but the DSC assistance won’t be on, so proceed with caution.

Exhaust filter warning light

If the exhaust filter is filling up, the exhaust warning will light up. 

There should also be an accompanying warning in the instrument panel. When it’s safe, follow the on-screen guidance.

Amber Triangle Generic Mode

When the general warning triangle is lit, it means that the instrument panel is displaying a non-critical warning or information message

Tyre Pressure Monitoring System

The Tyre Pressure Monitoring System (TPMS) light will come on to signal that either one or more of the vehicle’s tyres are under-inflated. There will also be an accompanying message on the instrument panel. When it’s safe, stop your vehicle and check your tyre pressure, and inflate if needed.

If the TPMS light flashes, there could be a system fault that will need inspecting.
