Coolant temperature gauge (3)
During severe operating conditions and stop-and-go city 
traf f ic, th e coola nt tempera ture may rise  close to th e 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.). 
Adaption 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.
Wa r n i n g !
• 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.

I Intermittent wiping
Vehicles with optional rain sensor:
One initial wipe, pauses between wipes are 
automatically controlled by a rain sensor 
monitoring the wetness of the windshield.
Notes:
With switch in this position, one wipe occurs 
when turning the electronic key in steering lock 
from position 0.
Optional rain sensor:
Do not leave in inte rmittent se tting w hen vehicle 
is taken to an automatic car wash or during 
windshield cleaning. Wiper will operate in 
presence of water spray at windshield, and wiper 
may be damaged as a result.

Note:
The windshield washer reservoir, hoses and nozzles are 
automatically heated.
For windshield and headlamp washer fluid mixing ratio 
see page 263.
Windshield wiper smears
If the windshield wiper smears the windshield, even 
during rain, activate the washer system as often as 
necessary. The fluid in the washer reservoir should be 
mixed in the correct ratio.Blocked windshield wiper
If the windshield wiper becomes blocked (for example, 
due to snow), switch off the wiper.
For safety reasons before removing ice or snow, remove 
electronic key from steering lock. Remove blockage.
Activate combination switch again (electronic key in 
steering lock position 1).

Power assistance
BrakesThe condition of the parking brake system is checked 
each time the vehicle is in the shop for the required 
maintenance service.
If the parking brake is released and the brake warning 
lamp in the instrument cluster stays on, the brake f luid 
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the 
reason for low brake f luid in the reservoir.
Have the brake system inspected at an authorized 
Mercedes-Benz Center immediately.
Al l checks and  service work on the  brake system shoul d 
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by 
Mercedes-Benz.
Wa r n i n g !
When the engine is not running, the brake and 
steering systems are without power assistance. 
Under these circumstances, a much greater effort is 
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without 
applying the brakes or through water deep enough 
to wet brake components, the first braking action 
may be somewhat reduced and increased pedal 
pressure may be necessary to obtain expected 
braking effect. Be sure to maintain a safe distance 
from vehicles in front.Resting your foot on the brake pedal will cause 
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby 
significantly reducing their effectiveness. It may 
not be possible to stop the vehicle in sufficient time 
to avoid an accident.
Wa r n i n g !
If other than recommended brake pads are 
installed, or other than recommended brake fluid 
is used, t he braking properties of th e vehic le can be 
degraded to an extent that safe braking is 
substantially impaired. This could result in an 
accident.
