34Using the system
AlternatorRead and observe
on page 35 first.
The warning light
lights up when the engine is running but the vehicle bat-
tery is not charging.
Seek assistance from a specialist garage immediately.
CAUTION
If in addition to the symbol the symbol » page 36 lights up while driving,
stop driving - risk of engine damage! Switch off the engine and seek assis-
tance from a specialist garage.
Door open
Read and observe
on page 35 first.
The indicator light
illuminates if one or several doors are opened.
On vehicles with MAXI DOT display, this indicator is replaced by a vehicle icon
on the display » page 44 .
Coolant
Read and observe
on page 35 first.
If the warning light
lights up or flashes , either the coolant temperature is
too high or the coolant level is too low.
The following message is shown in the MAXI DOT display. Check engine coolant! Owner's manual!
›
Stop the vehicle, switch off the engine, and check the coolant lev-
el » page 185 .
›
If the coolant level is too low, add coolant to the reservoir » page 186.
If the indicator light
does not illuminate after adding coolant and switching
on the ignition, you may continue your journey.
If the coolant is within the specified range and the warning icon is still
lit
after switching on the ignition, then there may be a malfunction of the cooling
fan.
›
Switch off the ignition.
› Check the fuse for the radiator fan, replace if necessary
» page 216, Fuses in
the engine compartment .
If the coolant level and fan fuse are OK and the warning icon
lights up again
after switching on the ignition,
stop driving!
Seek help from a specialist garage.WARNING■ Carefully open the coolant expansion bottle. If the engine is hot, the cool-
ing system is pressurized - risk of scalding! It is therefore best to allow the
engine to cool down before removing the cap.■
Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off - risk of injury!
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.
Boot lid

If the indicator light
illuminates , this indicates a partial failure of the power
steering and the steering forces can be greater.
›
Stop the car, turn the ignition off and on again.
The powered steering is fully functional again if the
