If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive

Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking

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

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‐

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

th e brakepads checked at a qualified specialist
wo rkshop, not only at everyservice displa yedby

Ne w brake discs and brakepads
New brakepads and brake discs on lyreach their
optimal braking ef fect af ter appro ximately
10 0 miles (100 kilome ters).
Unti lth en, compensate forth ere duced braking
ef fect by applying greater pressure tothe brake

mends that you only ha vebrakepads and brake
discs which are appr ovedby Mercedes-Benz
ins talled on your vehicle.
Other brake discs or brakepads may compromise

Pa rking brake &
WARNING Risk of skidding or an acci‐
dent bybraking with the parking brake
If yo u ha vetobrake your vehicle with the
parking brake, the braking dis tance is consid‐
erab lylonger and the wheels may loc k.There
is an increased risk of skidding and/or acci‐
dent. #
Only brake theve hicle with the parking
brake if the service brake has failed. #
Inthis case, do not apply the parking
brake with too much forc e. #
Ifth e wheels loc k,immediately release
th e parking brake as much as required

hicles with a manual parking brake
When driving on wetro ads or dirt-co vered sur fa‐
ces, road salt or dirt may getinto the parking
brake. This causes cor rosion and a reduction of
braking forc e.
In order topreve ntthis, drive with the parking
brake lightly applied from time totime.
When doing so, drive for a dis tance of appr ox‐
imately 300 ftat a maximum speed of 13mph
(20 km/h).
The brake lights do not light up when you brake
th eve hicle with the parking brake. Information about driving on

Avoid tire ruts and brake carefully. The
refore , in heavy rain or other conditions in
which hydroplaning can occur, drive as follo ws:
R Reduce your speed
R Avoid tire ruts
R Brake carefully
Driving on flooded roads
Bear in mind that vehicles tr aveling in front or in

When driving off-road on steep inclines, you must
make sure that the DEF tank is su fficiently filled.
Therefore, ensure a le vel of at least ten li ters

When driving off-road and on con stru ction sites,
sand, mud and water,also mixed with oil, can get
