  • Airbag crash sensors damaged often due to a collusion or water damage.
  • Problems with seat belt / buckle.

If this light comes on please get in touch with roadside assistance.

 

warning-lights-abs.png

 

ABS Warning Lamp

 

Also know as ABS (Anti-lock Braking system) is an add-on safety system to the van’s regular brakes.

This light will flash when you turn the vehicle ON. If the light comes ON while driving, it means the vehicle needs service.

If ABS is the only light in your panel, the regular brakes are working, but the ABS is not.

If it comes on with the brake warning light , it could indicate that the brake system is failing and you should stop straight away and get in touch with roadside assistance.

You will see this light if you turn your 4WD front axle lock ON, since that disables ABS.

ABS helps to prevent the wheels from locking when under hard braking. If ABS fails, normal brakes are unaffected, though they operate without ABS. The most common cause for ABS warning light is a damaged wheel speed sensor. Diagnostics and fault code scanning should determine the malfunction.

Can I still drive with my ABS Warning Lamp ON?

If the ABS light comes on by itself you should still have normal, unassisted braking, so it's safe to continue your journey – but keep your distance, take extra care, and get it checked as soon as possible. 

Door Open Warning Lamp

 

Also known as Door(s) open warning lamp

It illuminates when you switch the ignition on and remains on if any door or the hood is open.

It is a safety indicator on your vehicle's dashboard that alerts you when one or more doors are not fully closed. It may illuminate when any door, including the driver's side, passenger side, or even the trunk or hatch, is slightly ajar.

Can I still drive with my Door Ajar Warning Lamp ON?

Even if the door seems closed, it might not be fully engaged, which can lead to safety concerns such as the door opening while the vehicle is in motion or the car's security system being compromised. If the light is on while you're driving, you should pull over and check all doors to ensure they are properly shut.

If the light comes back on again after topping up please stop the vehicle and get in touch with roadside assistance.

 Engine Oil Pressure Light

 

Also known as the low engine oil or low oil pressure light.

This light will come ON when you turn your engine ON.

Fasten Seatbelt Warning Lamp

It illuminates when the vehicle detects that the driver or one or more passengers have not fastened their seatbelts. This warning light is typically accompanied by an audible chime, reminding drivers and passengers to buckle up for safety. In some vehicles, the warning light may stay on for a short time after starting the engine and then turn off once the seatbelts are properly secured.

If the Fasten Seatbelt Warning Lamp is on, it’s important to immediately buckle up, as seatbelts are one of the most effective safety features in protecting you during a collision. The light may also remain on if a passenger in the rear seat hasn’t fastened their belt or if there's an issue with the seatbelt sensor.

The symbol will appear as a reminder for the front passenger to buckle up their seatbelt.

Can I still drive with my Fasten seatbelt Warning Lamp ON?

This light will appear in orange amber if the system is turned OFF.

Its main function is the enhancement of handling, maneuverability, and stability at different speeds:

  • Low Speeds: The rear wheels turn in the opposite direction of the front wheels to reduce the vehicle's turning radius, making it easier to navigate tight spaces and park.
