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.

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.

windshield washer reservoir.
7Windshield wipers
0OffI 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. This
will not occur with a door open.
Notes:
With switch in this position, one wipe occurs
when turning the electronic key in starter switch
from position 0. However, this might cause
scratches in a dry windshield. Turn combination
switch to Off position before turning the
electronic key in starter switch from position 0.
Do not leave in intermittent setting when vehicle
is taken to an automatic car wash or during
windshield cleaning. Wipers will operate in
presence of water spray at windshield, and
wipers may be damaged as a result.
II Normal wiper speed
III Fast wiper speed
Vehicles without optional rain sensor:
If the vehicle is standing still, the wiper will
switch back one setting.

Blocked windshield wipers
If the windshield wipers become blocked (for example,
due to snow), switch off the wipers.
For safety reasons before removing ice or snow, remove
electronic key from starter switch. Remove blockage.
Activate combination switch again (electronic key in
starter switch position 1).
Emergency operation of windshield wipers
In case of windshield wiper malfunction in switch
positions I or III, turn combination switch to wiper
setting II. Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.Windshield wipers smear
If the windshield wipers smear 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.
See page 320 for instructions on filling up the
windshield washer reservoir.
See page 356 for instructions on replacing wiper blade
inserts.
Windshield and headlamp washer fluid mixing ratio
For temperatures above freezing:
MB Windshield Washer Concentrate “S” and water.
1 part “S” to 100 parts water
(40 ml “S” to 1 gallon water).
For temperature below freezing:
MB Windshield Washer Concentrate “S” and
commercially available premixed windshield washer

1 part “S” to 100 parts solvent
(40 ml “S” to 1 gallon solvent).

Power assistance
BrakesExcessive use of road salt and other snow melting
chemicals spread on roads during the winter months
may cause a build up of moisture or residue to form on
the braking components. This build up or residue could
cause light corrosion of the braking components if the
vehicle is parked with the brakes cold. Apply steady and
even braking pressure when stopping the vehicle to
warm up and dry the brake components.
Important!
Please pay attention to the function of the brake assist
system (BAS), see page 271.
The 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 fluid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
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 or salty road conditions,
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.

259 Driving instructions
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.Caution!
When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.
Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
When starting off on a slippery surface, do not allow one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.
Wa r n i n g !
If other than recommended brake pads are
installed, or other than recommended brake fluid
is used, the braking properties of the vehicle can be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.
