Warning and indicator lamps in the instrument cluster

General notes

Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and

indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These

warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is

started or during a journey.

N The red coolant warning lamp lights up while the engine is running.

The coolant level is too low.

If the coolant level is correct, the airflow to the engine radiator may be blocked or

the electric engine radiator fan may be malfunctioning.

The coolant is too hot and the engine is not being cooled sufficiently.

X Observe the additional display messages on the multifunction display.

X Stop the vehicle immediately, paying attention to road and traffic conditions,

and switch off the engine.

X Secure the vehicle against rolling away ( Y page 166).

X Leave the vehicle and keep a safe distance from the vehicle until the engine has

cooled down.

X Check the coolant level and top up the coolant, making sure to observe the

warning notes ( Y page 340).

X If you have to top up the coolant frequently, have the engine cooling system

checked.

X Make sure that the air supply to the engine radiator is not blocked, e.g. by frozen

slush.

X Do not start the engine again until the coolant temperature is below 120 †. The

engine may otherwise be damaged.

X Drive to the nearest qualified specialist workshop.

X Avoid heavy loads on the engine as you do so, e.g. driving in mountainous terrain

and stop-start traffic.

N The red coolant warning lamp lights up while the engine is running.

The coolant temperature has exceeded 120 †. The airflow to the engine radiator

may be blocked or the coolant level may be too low.

G WARNING

The engine is not being cooled sufficiently and may be damaged.

Never drive with an overheated engine. Driving when your engine has overheated

can cause any fluids that may have leaked into the engine compartment to catch

fire.

In addition, steam from an overheated engine can cause serious burns, which can

occur just by opening the bonnet.

There is a risk of injury.

X Observe the additional display messages on the multifunction display.

X Stop the vehicle immediately, paying attention to road and traffic conditions,

and switch off the engine.

X Secure the vehicle against rolling away ( Y page 166).

R the tyres may wear excessively and/or unevenly, which may greatly impair tyre

traction

R the driving characteristics, as well as steering and braking, may be greatly

impaired
