Parking brake
When driving on wet roads or dirt covered
surfaces, road salt and/or dirt can get into
the parking brake.
To prevent corrosion and a reduction in the
braking power of the parking brake, observe
the following:
X
From time to time, lightly engage the
parking brake before driving off.
X
Drive a distance of approximately 110 yds
(100 m) at a maximum speed of 12 mph
(20 km/h).
G
Warning!
While performing this procedure please
assure that the vehicle is stopped before
applying the parking brake. Otherwise the
rear wheels could lock up. You could lose
control of the vehicle and cause an
accident. In addition, the vehicle’s brake
lights do not light up when the parking
brake is engaged. Make sure not to
endanger any other road users when you
engage the parking brake.
Driving off
Warm up the engine smoothly. Do not place
full load on the engine until the operating
temperature has been reached.
!
When driving off on a slippery surface, do
not allow a drive wheel to spin for an
extended period with the ESP
®
switched
off. Doing so may cause serious damage to
the drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
!
Simultaneously depressing the
accelerator pedal and applying the brakes
reduces engine performance and causes
premature brake and drivetrain wear which
is not covered by the Mercedes-Benz
Limited Warranty.
Hydroplaning
Depending on the depth of the water layer on
the road, hydroplaning may occur, even at low
speeds and with new tires.
X
Reduce vehicle speed.
X
Avoid track grooves in the road.
X
Brakes cautiously in the rain.
Standing water
!
Do not drive through flooded areas.
Before driving through water, determine its
depth.
If you must drive through standing water,
drive slowly to prevent water from entering
the passenger compartment or the engine
compartment. Water in these areas could
cause damage to electrical components or
wiring of the engine or transmission, or
could result in water being ingested by the
engine through the air intake causing
severe internal engine damage. Any such
damage is not covered by the Mercedes-
Benz Limited Warranty.
i
Select the raised level (Y page 186)
before driving through standing water.
