Coolant temperature gauge
Turn the electronic key in starter switch to position 1
or 2.
Call up the trip odometer and main odometer by
pressing button è or ÿ on the multifunction
steering wheel. See page 106.
Press button j or k until the coolant
temperature gauge appears.
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to 120
°C.
The engine should not be operated with the coolant
temperature above 120
°C. Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Note:
Excessive coolant temperatures trigger a warning in the
multifunction display. See page 298.

Warning!
• Driving when your engine is badly overheated
can cause some fluids which may have leaked
into the engine compartment to catch fire. You
could be seriously burned.
• Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it.
Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.
