Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. This means the coolant
temperature gauge must display less than
70 °C. You could otherwise be scalded by
escaping hot coolant.
Coolant consists of water and antifreeze/cor -
rosion inhibitor. Only check the coolant leve l
when the vehicle is on a level surface and th e
engine has cooled down. Checking the coolant level The expansion tank is located in the engin
e
compartment on the right-hand side of the
vehicle . 1

Troubleshooting
29
1 Problem Possible cause/consequence Suggested solutions
Vehicles with a petrol engine:
The engine is not running
smoothly and is misfiring. The engine electronics or
a
mechanical component of the
engine control unit have been
damaged. X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist work-
shop .
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. A coolant temperature of over
120 °C is displayed. The coolant
warning lamp may also be on and
a warning signal may sound
(
Y page 123). The coolant level is too low. The
coolant is too hot and the engin
e
is no longer being cooled suffi-
ciently. X
Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 209). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct, the
radiator fan may be faulty. The
coolant is too hot and the engin
e
is no longer being cooled suffi-
ciently. X
If the coolant temperature is less than 120°C, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. when driving on
mountain roads and stop/start driving . Practical advice
