Seat Leon >> Coolant Level* / temperature

The warning lamp lights up if the coolant temperature is too high or if the coolant level is too low.

There is a fault if:
• The warning symbol does not go out again after a few seconds.
• The warning lamp lights up or flashes while the vehicle is moving, while three acoustic warning signals emitted. are emitted.

This means that either the coolant level is too low or the coolant temperature is too high.

Coolant temperature too high
The following text is displayed in the instrument panel display9): CHECK COOLANT! INSTRUCTIONS MANUAL. First look at the coolant temperature gauge. The coolant temperature is too high if the needle is over the warning area on the dial. Stop the vehicle, switch off the engine and wait for it to cool down. Check the coolant level.

If the coolant level is correct, the overheating may be caused by a malfunction of the radiator fan. Check the radiator fan fuse and have it replaced if necessary.

If the warning lamp lights up again after driving on for a short distance, stop the vehicle and switch off the engine. Contact an Authorised Service Centre or a qualified workshop.

Coolant level too low The following text is displayed in the instrument panel display10): CHECK COOLANT! INSTRUCTION MANUAL.

First look at the coolant temperature gauge. If the needle is in the normal range, top up with coolant at the earliest opportunity WARNING.

WARNING

• If your vehicle is immobilised for any technical reasons, move it to a safe distance from traffic. Turn off the engine, turn on the hazard lights and place the warning triangle.
• Never open the bonnet if you can see or hear steam or coolant escaping from the engine compartment. Risk of scalding. Wait until you can no longer see or hear escaping steam or coolant.
• The engine compartment of any motor vehicle is a dangerous area! Before carrying out any work in the engine compartment, switch off the engine and allow it to cool down. Always note the corresponding warnings

WARNING

• Before opening the bonnet, read and observe the warnings on  “Working in the engine compartment”.

• If the brake warning lamp does not go out, or if it lights up when driving, the brake fluid level  “Brake fluid” in the reservoir is too low. Risk of accident. Stop the vehicle and do not drive on. Obtain technical assistance.

• If the brake warning lamp up together with the ABS warning lights up together with the ABS warning lamp ABS could be out of action. This could, the control function of the ABS could be out of action. This could cause the rear wheels to lock quickly when you brake. This could cause the rear to break away. Risk of skidding. Drive carefully to the nearest qualified workshop and have the fault corrected.

Engine oil pressure This warning lamp indicates that the engine oil pressure is

This warning lamp indicates that the engine oil pressure is too low.

If this warning symbol starts to flash, and is accompanied by three audible warnings, switch off the engine and check the oil level. If the oil level is too low, add more engine oil.

The following text is displayed in the instrument panel display14): STOP ENGINE OIL PRESSURE INSTRUCTIONS MANUAL. If the symbol flashes although the oil level is correct, do not drive on. The engine must not even run at idle speed. Obtain technical assistance.

Anti-lock brake system (ABS) A warning lamp system monitors the ABS.

A warning lamp system monitors the ABS.

The warning lamp for a few seconds when the ignition is should light up for a few seconds when the ignition is switched on. It goes out again after the system has run through an automatic test sequence.

There is a fault in the ABS if:
• The warning lamp up when the ignition is switched on. does not light up when the ignition is switched on.
• The warning lamp does not go out again after a few seconds.
• The warning lamp lights up when the vehicle is moving.

The vehicle can still be braked in the normal way (except that the ABS control function will not function). Please take the vehicle to a qualified workshop as soon as possible. For further information on the ABS see the 􀂟 page 169.

If a fault occurs in the ABS, the ESP* warning lamp will also light up.

Brake system fault
If the ABS warning lamp together with the brake warning lamp lights up together with the brake warning lamp the ABS function, but also a possible fault, this indicates not only a fault in the ABS function, but also a possible fault in the brake system WARNING.

WARNING

When the TCS is operating while driving, the warning lamp flashes. If the system is deactivated or if there is any fault in the same, the warning lamp will remain lit.

It will also come on if a fault should occur in the ABS because the TCS operates in conjunction with the ABS. For further information.

Soot accumulation in the diesel engine particulate filter* if the symbol  lights, soot has

if the symbol built up in the diesel engine particulate filter lights, soot has built up in the diesel engine particulate filter due to continuous short trips. In this case, drive the vehicle at a constant speed of at least 60 km/h (with an engine speed of about 1400 rpm) for about 10 minutes. The increase in temperature generated may burn the accumulated soot in the filter.

If the symbol bring the vehicle to a specialized workshop is not deactivated, bring the vehicle to a specialized workshop to repair the fault.

For more information on the diesel particulate filter.

WARNING

• The diesel engine particulate filter may reach extremely high temperatures; it should not enter into contact with flammable materials underneath the vehicle. Failure to comply could result in fire.

Fig. 47 Centre console: tyre monitor system button

The tyre monitor indicator compares wheel revolutions and uses this information to compare the diameter of each wheel using the ABS sensors. If the diameter of a wheel changes, the tyre monitor indicator lights 􀁾. The wheel diameter changes when:

• Tyre pressure is insufficient.
• The tyre structure is damaged.
• The vehicle is unbalanced because of a load.
• The wheels of one axle are under more pressure (for example, driving with a trailer or on extreme slopes).
• The vehicle is fitted with snow chains.
• The emergency wheel is fitted.
• The wheel on one axle is changed.

Tyre pressure adjustment
Following the modification to tyre pressure or changing one or more wheels, the button  fig. 47 must be kept pressed while the ignition is on, until an acoustic signal is heard.

If the wheels are under excessive load (for example, driving with a trailer or heavy load), the tyre pressure must be increased to the recommended value for a full load (see the sticker on the inside of the fuel flap). If the tyre monitor system button is pressed the new tyre pressures are confirmed.

The warning lamp functions: has the following functions:

• It will light for about 2 seconds when the ignition is switched on while a test of the function is carried out.
• It flashes when the ESP is activated when driving.
• It will light up continuously if there is a malfunction in the ESP.
• It will light up continuously if the ESP is switched off.
• It will also come on if a fault should occur in the ABS because the ESP operates in conjunction with the ABS.

If the ESP warning lamp and stays on after the engine is started, lights up and stays on after the engine is started, this may mean that the control system has temporarily switched off the ESP.

In this case the ESP can be reactivated by switching the ignition off and then on again. If the warning lamp goes out, this means the system is fully functional.

For vehicles with power steering, the level of steering assistance depends on the vehicle's speed and on the steering angle.

The warning lamp should light up for a few seconds when the ignition is switched on. It should go out when the engine has started running.

If the battery is disconnected, the indicator remains lit, even with the engine running. The warning light only goes off after a distance of approx. 50 m.

There is a fault in the electromechanical steering system if the lamp does not go out or light up, whilst the vehicle is in motion. The indicator may appear in two different colours to indicate faults. If it lights yellow, this indicates a minor fault. If it lights red, seek workshop assistance immediately, if no assistance is available stop driving. Stop the vehicle and seek technical assistance. The power steering does not work if the battery is flat or if the engine is off (for example, for towing). You should take into account that you will need considerably more power than normal to steer the vehicle if the steering assistance is reduced or has failed completely
