Note s on brakes &
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 (/ page124).
% Cha
nge the shift range in good time when
cruise control is acti vated. Obser vethe driv‐
ing tips (/ page111).
Yo uth ereby make use of the braking ef fect of the
engine and do not ha vetobrake as of tento main‐
tai nth e speed. This relie vesth e load on the
service brake and pr events the brakes from over‐
heating and wearing tooqu ickl y. Heavy and light loads
If
th e brakes ha vebeen subjected toa heavy
load, do not stop theve hicle immediatel y.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 moderately,
yo u should occasionally test their ef fectiveness.
To do this, brake more firm ly from a higher speed
while pa ying attention tothe traf fic 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. Maintain a grea ter dis tance tothe
ve hicle in front.
While paying attention tothe traf fic conditions,
yo u should brake theve hicle firm lyafte r 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 brake‐
pads can increase braking dis tances consid‐
erably, or braking may happen on only one
side
R Maintain an especially large safe 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 depress the brake pedal at the end
of a journey and af terth est art of a new jour‐
ney
Checking the brakepad thickness
In addition tomonitoring using the brakepad wear
sensor, regular lymonitor and check all of the
brakepads byper form ing a visual inspection to
look for pad material wear.
If yo u are unable tocheck the brakepad wear on
th e inside of the wheels, remo vethe wheels if
yo u possess there qu ired skills, or visit a qualified
specialist workshop.
If th e brakepad material thickness is less than
0. 12 in (3 mm), ha vethe brakepads checked and
re placed at a qualified specialist workshop, if
necessar y.
Do not solely rely on the brakepad wear sensor. 11 4
