Toyota AYGO Dashboard Warning Lights

Toyota AYGO Dashboard Warning Lights

The AYGO has been manufactured by Toyota since 2005 with the second and current model generation being released in 2014. Here we cover the Toyota AYGO dashboard warning lights for both the first generation (Mk 1) and the second generation (Mk 2). Unless otherwise stated, the warning light description applies to both generations.

The dashboard layout and warning light location will vary depending on the model version and the year of manufacture of your AYGO. Note; several warning lights illuminate when the ignition is switched on and should go out shortly after the engine has started. This is part of the self-check system and is normal.



SymbolWarning Description and Action
Toyota AYGO Battery Dashboard Warning Light
Battery
The Toyota AYGO battery warning light illuminates in red. If it comes on when driving, there's a problem with the charging system. If the battery is not being charged, there is a limited amount of time before the engine will shut down. Immediately switch off any non-essential vehicle systems that are consuming electric and find a safe place to park up and stop. Call a Toyota approved workshop for assistance.
Toyota AYGO Brake System Dashboard Warning Light
Brake
The Toyota AYGO brake warning light illuminates in red. If it comes on when driving, it indicates two possibilities:
1. Low brake fluid level. Brake fluid levels can fall over time as brake pads wear. If there's a sudden drop in brake fluid level, it may indicate a leak in the system. This will severely reduce braking performance.
2. Brake system malfunction. A malfunction has occurred in the vehicle's brake system.
Warning
It's advised to not continue driving if the brake warning light comes on as it may be dangerous. Stop in a safe place and contact a Toyota workshop.
Note
On the Mk1 version of the Toyota AYGO, this warning light also illuminates when the hand brake is on.
Toyota AYGO Oil Pressure Dashboard Warning Light
Oil Pressure
Engine oil is used to lubricate the internal components of the engine. If the Toyota AYGO low engine oil pressure warning light comes on, it means that the oil may not have sufficient pressure to lubricate all components. The red 'STOP' light may also illuminate. This in turn results in an increase in friction (metal-on-metal) that may lead to engine seizure.
Warning
To prevent engine damage, it's advised to stop the car safely, but as quickly as possible in a safe place and contact a Toyota workshop. It's unlikely you'll be able to continue your journey.
Toyota AYGO Engine Coolant Overheating Dashboard Warning Light
Coolant
This warning light means your Toyota AYGO engine coolant is overheating. If the engine coolant becomes too hot, severe damage may occur. Depending on your engine version, the coolant light will flash, then stay on, or just stay on. The red 'STOP' light may also illuminate. A loss of engine power may also be experienced (for example, the speed of the vehicle does not increase). You may also notice steam coming from under the bonnet / hood. To help prevent damage, follow this procedure:
1. Stop the vehicle in a safe place and switch off the engine.
2. If there is no steam, open the bonnet / hood. If there is steam, wait for it to subside before lifting the bonnet / hood.
3. Wait several minutes for the engine to cool, then inspect the hoses and radiator for any leaks. If there are leaks, do not continue to drive and contact a Toyota workshop.
4. If no leaks are occurring, check engine coolant level is between the MIN and MAX marker on the tank and add coolant if required. You can use normal water in an emergency. If the coolant levels are satisfactory and do not require topping up, there may be a fault with the cooling system. Contact a repair shop before continuing.
5. After topping up with coolant, start the engine and switch on the air conditioning system. This will operate the radiator fan - check it is working (you can hear it) and check again for any leaks.
6. If the fan is not operating, immediately switch off the engine and contact a repair workshop.
7. If the fan is working and there are no leaks, you can continue your journey. Check to ensure the warning light goes out and have your vehicle inspected soon.




Toyota AYGO STOP Dashboard Warning Light
STOP
The Toyota AYGO STOP warning light illuminates due to a malfunction in:
• Engine oil pressure (too low)
• Engine coolant temperature (too high)
If the red STOP warning light illuminates, taking traffic conditions into account, stop the vehicle, switch off the engine and contact a Toyota workshop.

• The electronic engine control system
• The electronic throttle control system
• The emission control system

If the check engine warning light illuminates, due to the many possible faults, diagnostic equipment is required to read fault codes. Usual faults related to the check engine light are:
• Bad oxygen sensor
• Catalytic converter issues
• Mass airflow sensor
• Spark plug / engine misfiring
If you notice the engine running 'rough', it could be a sign of misfiring which has the potential to damage the engine and catalytic converter.

Toyota AYGO ABS Dashboard Warning Light
ABS
The Toyota AYGO ABS warning light staying on constantly indicates a fault with:
• The ABS; or
• The brake assist system
ABS, or Anti-lock Braking system is an added safety system to normal brakes. Essentially the system prevents wheel lock under emergency braking, therefore allowing the driver to steer. The failure of the ABS system is often due to the sensor and normal brake will continue to work even with an ABS fault. The brake assist system applies greater brake force in emergency braking situations. It helps to reduce stopping distances and combines with ABS. You can continue to drive with an ABS fault light on, but without the benefit of these safety features. Have the system serviced as soon as possible.




Toyota AYGO Power Steering Dashboard Warning Light

Flashes: When VSC, TRC or hill-start assist is operating, the light flashes.
Traction Control
Part of the Vehicle Stability Control system is traction control (TRC). This helps to prevent wheel spin and is often beneficial in pulling away quickly such as out of a junction for example.
