Outside Temperature Indicator
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 condi­
tions (stop-and-go or moderate,
constant driving) and amount of
temperature change.
Warning!
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 freezing point do not
guarantee that the road
surface is free of ice.

Brake Pad Wear Indicator Lamp
The brake pad wear indicator
lamp in the instrument cluster
comes on when the key in the
steering lock is turned to posi­
tion 2 and it goes out when the
engine is running. If the indicator
lamp lights up during braking, this
indicates that the front wheel
brake pads are worn down (ve­
hicles equipped with ASR front
and/or rear wheel brake pads).
Have the brake system checked at
an authorized Mercedes-Benz
dealer as soon as possible.
Brake Warning Lamp
The brake warning lamp will come
on if insufficient brake fluid is in
the reservoir (key in steering lock
position 2 and parking brake
released).
When the minimum mark on the
reservoir is reached, have the
brake system checked for brake
pad thickness and leaks.
To test the brake warning lamp,
turn key in steering lock to posi­
tion 2. The brake warning lamp
comes on dimly, and should go
out when the engine is running.
Warning!
Driving with the brake warning
lamp on, can result in an acci­
dent. Have your brake system
checked immediately if the
brake warning lamp stays on.
Don't add brake fluid before
checking the brake system.
Overfilling the brake fluid
reservoir can result in spilling
brake fluid on hot engine parts
and the brake fluid catching
fire. You can be seriously
burned.
