WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. #
Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking
ef fect. &
WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may overheat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. Downhill
gradients
On long and steep downhill gradients you should
obse rveth efo llowing instructions:
R invehicles with an automatic transmission,
shift down toshift ranges 2or 1in good time
so that the engine is running at a medium to
high engine speed (/ page117).

WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may overheat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. If
th e brakes ha vebeen subjected toa heavy
load, do not stop theve hicle immediately. Drive
on for a short while. The brakes cool down more
qu ickly in the air flow.
If th e brakes ha vebeen used only moderatel y,
yo u should occasionally test their ef fectiveness.
To do this, brake more firm lyfrom a higher speed
while paying attention tothe tra ffic conditions.
The brakes will grip better as a result.
We tro ad sur faces
If yo u ha vebeen driving for a long time in heavy
ra in without braking, there may be a dela yed
re sponse when youfirs t apply the brakes. This
may also occur af ter driving thro ugh a car wash
or deep water.Yo u must depress the brake pedal
more firm ly. Main tain a longer di stance tothe
ve hicle in front.
While paying attention tothe tra ffic conditions,
yo u should brake theve hicle firm ly af ter driving
on a wetro ad sur face or thro ugh a car wash. This
heats the brake discs so that they dry more
qu ickl y,which pr otects them against cor rosion.
Limited braking ef fect on salt-trea tedro ads:
R a layer of salt on the brake discs or brakepads
can increase braking dis tances conside rably,
or braking may happen on only one side
R maintain an especially lar gesafe dis tance to
th eve hicle in front
To remo vethe la yer of salt:
R apply the brakes from time totime, paying
attention totraf fic conditions
R carefully dep ress the brake pedal at the end
of a journey and af terth est art of a new jour‐

If yo ufa ilto adapt your driving style, cruise con‐
