KEYLESS-GO with you.


Never store the SmartKey with
KEYLESS-GO together with:

Electronic items such as a cellular
phone or another SmartKey with

Trip odometer
Make sure you are viewing the trip odome-
ter display (
page 150).

If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel (
page 151) until the trip odom-
eter appears.

Press and hold the reset button on the
instrument cluster (
page 148) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(page 24) denotes excessive engine
speed.To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature is displayed in
the multifunction display (
page 150).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 com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
The outside temperature indicator is not de-

is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
