Read and observe on page 30 first.
The
indicator light remains illuminated until the engine reaches operating
temperature
1)
. Avoid high speeds, full throttle and high engine loads.

too high or the coolant level is too low.
The following message is shown in the MAXI DOT display.
Check coolant! Owner's manual!
›
Stop the vehicle, switch off the engine and check the coolant lev-
el » page 133.

the engine compartment.
If the coolant level and fan fuse are both OK but the indicator light
is never-
theless still illuminated,
do not continue your journey!

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.
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.
Power steering
Read and observe on page 30 first.
If the indicator light
is illuminated, there is a fault in the power steering sys-
tem.
The power steering operates with reduced steering assist or does not function
at all.
Seek assistance from a specialist garage immediately.
Electronic Stability Control (ESC)
Read and observe on page 30 first.
The warning light
flashes to show that the ESC is currently operating.
If the warning light
illuminates, there is a fault in the ESC.
The following message is shown in the MAXI DOT display.
Error: stabilization control (ESC)
or
Error: traction control (ASR)
Seek assistance from a specialist garage immediately.
If the warning light
illuminates immediately after you start the engine, the
