We recommend that you carry the electronic reserve
key plus mechanical key with you and keep it in a safe
place (e.g. your wallet) so that it is always handy. Never
leave the electronic reserve key in the vehicle.

Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys can only be
obtained from your authorized Mercedes-Benz Center.

activates the start lock-out. The engine cannot be
started.
Inserting the electronic key in the steering lock
deactivates the start lock-out.Note:
In case the engine cannot be started (vehicle’s battery is
in order), the system is not operational. Contact an
authorized Mercedes-Benz Center or call 1-800-FOR-
MERCedes (in the USA) or 1-800-387-0100 (in Canada).

•Aim transmitter eye at a receiver of either door
handle. Check the batteries of the electronic main
key, see page264, or synchronize the remote
control, see page266.

Coolant temperature gauge (3)
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.Outside temperature indicator (5)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
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.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.
