Land Rover Discovery: Warning lamps and indicators

Do not ignore warning lamps or indicators. Take appropriate action as soon as possible. Failure to do so may result in death or serious injury, or serious damage to the vehicle.

RED warning lamps are for primary warnings. A primary warning must be investigated immediately by the driver or qualified assistance, before continuing.

AMBER and YELLOW warning lamps are for secondary warnings. Some indicate that a vehicle system is in operation, others indicate that the driver must take action and then seek qualified assistance as soon as possible.

GREEN and BLUE lamps within the Instrument panel indicate a system's status.

Lamp check

A warning lamp bulb check is initiated when the ignition system is switched on and lasts for 3 seconds (except for the airbag warning lamp, which will remain on for 6 seconds). If any warning lamp remains on after this period, investigate the cause before driving.

Some warning lamps have associated messages displayed in the Message centre.

Note: Not all warning lamps are included in the check (e.g., high beam headlamps and direction indicators).

Note: If a trailer with LED lights is connected to the trailer socket, the bulb check may not be performed.

BATTERY CHARGE (RED)

Illuminates as a bulb check when the ignition is switched on and extinguishes when the engine is started.

If the lamp remains on or illuminates while driving, there is a fault with the battery charging system and a message will be displayed in the Message centre. Seek qualified assistance urgently.

BRAKE (RED)

Illuminates briefly as a bulb check, when the ignition is switched on.

If the lamp illuminates while driving, suspect low brake fluid level or a fault with the Electronic Brake Distribution (EBD) system.

Stop the vehicle as soon as safety permits and check and top up the brake fluid, if necessary. If the lamp remains illuminated, seek qualified assistance before continuing.

CRITICAL WARNING MESSAGE (RED)

Illuminates when a critical warning message is available in the Message centre.

ENGINE TEMPERATURE (RED)

Illuminates when the engine temperature is too high. The Message centre will also display the message ENGINE OVERHEATING.

Stop the vehicle as soon as safety permits and seek qualified assistance before continuing.

LANE DEPARTURE WARNING (RED)

If the Lane Departure Warning (LDW) system detects that the vehicle has crossed either of the lane markings that it is travelling within, without activation of the appropriate direction indicator, then the relevant lane will illuminate red. This will also be accompanied by a vibration felt through the steering wheel.

LOW OIL PRESSURE (RED)

If the lamp flashes or illuminates while driving, stop the vehicle as soon as safety permits and switch off the engine immediately.

Check and top up the oil level, if necessary. Start the engine; if the lamp remains illuminated, switch the engine off immediately and seek qualified assistance before continuing.

PARKING BRAKE (RED)

Illuminates when the Electric Parking Brake (EPB) is correctly applied. If the lamp flashes, a fault has been detected. Seek qualified assistance urgently.

SEAT BELT (RED)

Illuminates, accompanied by a chime, when the vehicle is in motion and an occupied front seat belt is unbuckled. The lamp will extinguish when the relevant seat belt is buckled.

Note: Objects on the front passenger seat may activate the Seat belt reminder feature. It is recommended that any objects placed on the front passenger seat are secured using the seat belt.

ADAPTIVE FRONT LIGHTING SYSTEM (AMBER)

Illuminates when there is a system fault. The headlamps will still operate, but without this feature operating correctly.

Seek qualified assistance as soon as possible.

AIRBAG (AMBER)

Illuminates as a bulb check, when the ignition is switched on, and extinguishes after 6 seconds.

If the lamp illuminates again, after the bulb check or when driving, there is a fault with the airbag system. Seek qualified assistance as soon as possible.

ANTI-LOCK BRAKING SYSTEM (ABS) (AMBER)

Illuminates briefly as a bulb check, when the ignition is switched on.

If the lamp remains on or illuminates while driving, there is a fault with the ABS system. Drive with care, avoiding heavy brake application and seek qualified assistance urgently.

AUTOMATIC SPEED LIMITER (AMBER)

Illuminates when the Automatic Speed Limiter (ASL) is active.

BRAKE (AMBER)

Illuminates briefly as a bulb check, when the ignition is switched on. If the lamp illuminates after starting the engine or while driving, suspect worn brake pads or a fault with the Emergency Brake Assist (EBA) system.

The vehicle can still be driven with care, but seek qualified assistance urgently.

DYNAMIC STABILITY CONTROL (DSC) (AMBER)

Flashes when DSC is active.

If there is a fault, it will remain illuminated and the Message centre will display DSC NOT AVAILABLE. The vehicle can still be driven, but without DSC assistance. Seek qualified assistance as soon as possible.

DYNAMIC STABILITY CONTROL (DSC) OFF (AMBER)

Illuminates when DSC is switched off. A chime will sound and a confirmation message will be displayed in the Message centre.

ENGINE/TRANSMISSION (AMBER)

Illuminates briefly as a bulb check, when the ignition is switched on. If the lamp illuminates when the engine is running, there is an emissions related fault with the engine or transmission.

The vehicle can be driven, but may enter Limp-home mode with the possibility of reduced performance. Seek qualified assistance as soon as possible.

If the warning lamp flashes while the engine is running, reduce speed and seek qualified assistance urgently.

EXTERNAL TEMPERATURE (AMBER)

Illuminates when the external temperature is low enough that ice may be present on the road.

FOLLOW MODE (AMBER)

Illuminates when the Adaptive Cruise Control (ACC) system is in Follow mode.
