Hyundai Tucson Airbag Warning Light
Airbag

Airbag Warning Light
The Hyundai Tucson airbag warning light illuminates in red for around 6 seconds when the ignition switch or
the Engine Start/Stop button is set to the ON position. If the warning light stays on, it means there’s a malfunction with the airbag / SRS (Supplemental Restraint System).

Brake Warning Light
The Hyundai Tucson brake warning light illuminates in red for around 3 seconds when the ignition switch or
the Engine Start/Stop button is set to the ON position. The brake warning light stays illuminated when the parking brake is on. If the warning light remains on when the parking brake  is properly released, it means there’s low brake fluid level in the reservoir. If driving, stop as soon as possible and top up the reservoir with brake fluid. Check for leaks. If any leaks are found, or the brake fluid does not require topping up, or the brake light remains on, do not continue driving. Note; try manoeuvring the hand brake lever around as the brake warning light remaining on sometimes is caused by a bad hand brake switch.

 


Hyundai Tucson ABS Warning Light
ABS

ABS Warning Light
ABS (Anti-lock Brake System) works by using sensors in each wheel to detect if a wheel is locking. When pressing the brakes hard, the ABS reduces brake pressure to keep the wheel rotating just at the point before it locks. This enables the driver greater control of the vehicle. The Hyundai Tucson ABS warning light comes on when the system has malfunctioned. In this instance however, normal brake will resume without the benefits of ABS. It is safe to continue driving, but have system checked as soon as possible. Usual causes for ABS malfunction is a wheel speed sensor.

ABS + Brake Warning Light
If the ABS and brake warning light both illuminate, it means there’s a fault with the Electronic Brake force Distribution (EBD). EBD allows for altering brake pressures on an individual wheel basis, therefore increasing braking efficiency. With EBD failure, avoid high speed driving and abrupt braking. Brakes may not operate as expected. Have system serviced by a Hyundai workshop as soon as possible. Note; when the ABS and brake warning light illuminate, the speedometer, odometer, or tripmeter may not work. The EPS warning light may also illuminate. Possible causes is faulty ABS module.

 





Hyundai Tucson EPB Warning Light

EPB Warning Light
The Hyundai Tucson EPB warning light means there’s a fault with the Electronic Parking Brake. If the EPB warning light illuminates along with the ESC warning light, it does not mean the EPB has malfunctioned.

 

 


Hyundai Tucson ESC Warning Light
ESC

ESC Warning Light
ESC (Electronic Stability Control) operates by use of sensors to determine where you are steering
and where the vehicle is actually going. To aid in stabilizing the vehicle, ESC applies braking pressure to any one of the vehicle’s brakes and intervenes in the engine management system to assist the driver
with keeping the vehicle on the intended path. If the amber ESC warning remains lit, it means there’s a fault with the system. ESC uses ABS sensors and can often be the cause of fault. If the ESC light flashes, it means the system is operating.

 


Hyundai Tucson Power Steering Warning Light
Power Steering

Power Steering Warning Light
The amber steering wheel / exclamation mark is the electronic power steering (EPS) fault light. If you have been making frequent left / right steering movements or had the steering placed at full lock while the engine is on, it may be a temporary fault where the system temporarily shuts off the power steering motor to prevent overheating. While the light is on, steering the vehicle will be more difficult. Have the system checked as soon as possible.

 


Hyundai Tucson Engine Malfunction Warning Light
MIL

Malfunction Indicator Light
The Hyundai Tucson malfunction indicator light (MIL), often referred to a the check engine light comes on and stays on when there’s a malfunction with the emission control system. Usual causes of the check engine warning light are faulty mass airflow sensor, faulty oxygen sensor or faulty exhaust gas recirculation valve (EGR). There are other possibilities and the only way to locate the fault is to use diagnostic equipment to read fault codes. Continued driving may cause damage to the emissions control system. On the petrol version of the Hyundai Tucson, if the check engine light is flashing, it usually means an engine misfire is occurring. In this instance, damage to the catalytic converter may occur. Immediately reduce speed until the light stops flashing. On diesel versions of the Tucson, a flashing check engine light is usually related to an error with the injection quantity adjustment which could result in loss of engine power, increased combustion noise and poor emissions.

 





Hyundai Tucson Battery Warning Light

Battery Warning Light
The red battery warning light remaining lit on the Hyundai Tucson dashboard indicates a charging problem. The fault may lie with the alternator belt – check that it is not broken or loose. Alternatively, the alternator may not be providing sufficient current to charge the battery, or the battery may be old and require replacement. If the light comes on while driving, immediately switch off any utilities that consume electricity and that are not essential. Drive immediately to a vehicle repair workshop as the engine may stop after a time.

 


Hyundai Tucson Oil Pressure Warning Light
