Warning Lights

Parking Brake Indicator

If the parking brake indicator illuminates or flashes, this indicates that the parking brake is not fully engaged or not fully released.  To remedy the situation, operate the parking brake switch once again to fully engage the switch on or off in the desired direction.  If the light turns off when the parking brake is fully released, the system is operating normally.

Brake System
Warning Light

If this warning light illuminates (or a buzzer sounds), stop the vehicle right away in a safe area. Ensure that the parking brake has been fully released, even if the system appears to be operating normally. Next check the brake fluid levels. If brake fluid levels are adequate, there could be a malfunction in the brake booster system and you should have your vehicle inspected by a Lexus dealer immediately.

Charging System Warning Light

The charging system warning light indicates a malfunction in the vehicle’s charging system. Immediately stop the vehicle in a safe place and contact your Lexus dealer. This warning light may indicate damage to the vehicle and could result in an accident.

SRS Warning Light

The SRS warning light indicates a malfunction in either the SRS airbag system, the seat belt pretensioner system, or the front passenger occupant classification system.  Have your vehicle inspected by a Lexus dealer immediately if this warning light comes on.  This warning light may indicate a problem that could lead to the vehicle operating abnormally and possibly causing an accident.

 

Open Door
Warning Light

If your vehicle’s open door warning light illuminates or its warning buzzer sounds, it is meant to alert vehicle inhabitants that a door or the vehicle trunk is not fully closed.  Please check to ensure that all the vehicle doors and the trunk are closed.

 

Security Indicator

This light works with the Immobiliser system to deter theft by preventing the hybrid system from starting until a registered key is within the vehicle. If illuminated, it means the key is likely in contact with a metal surface. If upon unlocking and starting the vehicle, the light does not turn off, there may be a problem with the vehicle security system and you should seek service at a Lexus dealer.

 

Driver’s Seat
Belt Reminder

The seat belt reminder light or buzzer warns the driver to fasten their seat belt.  To turn off the warning light and/or buzzer, the driver must fasten their seat belt.

Front Passenger’s Seat Belt Reminder

The seat belt reminder light or buzzer warns the front seat passenger to fasten their seat belt.  To turn off the warning light and/or buzzer, the front passenger must fasten their seat belt.

Rear Passengers’ Seat Belt Reminder

The rear passengers’ seat belt reminder lights are meant to warn the driver that the rear seat passengers are not wearing their seat belts.  To remedy the situation, have all rear seat passengers buckle their seat belts.

This warning indicator will be accompanied by a buzzer, and indicates that the engine is overheating.  Immediately stop the vehicle in a safe spot.  Continued operation of the vehicle could be dangerous.

System Warning

If the power steering system warning light is illuminated or the buzzer sounds, this is indicating a malfunction in the power steering system. Have the vehicle inspected immediately by your Lexus dealer.

Tire Pressure
Warning Light

This light indicates low tire inflation pressure, from natural causes or a flat tire.  Adjust the tire inflation pressure to the specified psi level, and the light should turn off within a few minutes.  The specified psi level is commonly shown on a sticker inside the driver’s door. If the tire pressure warning light does not turn off, blinks, or comes on after blinking for one minute, there is a malfunction in the tire pressure warning system and it should be checked by your Lexus service center.

Indicator Lamp

This warning light indicates a malfunction in the electronic engine control system, the electronic throttle control system, or the electronic automatic transmission control system.  Whenever this light turns on you should have your vehicle inspected immediately by your Lexus dealer.

Low Fuel Level
Warning Light

The low fuel level warning light indicates that the remaining fuel is approximately 4.0 gal. To remedy the situation, please find the nearest gas station to refuel your vehicle.

Headlight Leveling System Warning

This light warns drivers that their automatic headlight leveling system is not working properly, and you should see your Lexus dealer.  The system should automatically adjust according to the weight load within the vehicle to ensure the headlights do not interfere with other road users. 

ABS Warning Light

When the anti-lock braking system (ABS) warning light becomes illuminated it means there is either a malfunction in the anti-lock braking system or in the brake assist system. Either issue should be attended to right away at a Lexus certified service provider.

Slip Indicator

The VSC, TRAC, or trailer sway control system is operating if the slip indicator light is flashing.  If the indicator light is fully illuminated there is a malfunction in the VSC system, TRAC system, hill-start assist control system, or trailer sway control, and you should have the vehicle inspected by your Lexus service provider immediately.
