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 disks so that they dry more
qu ickl y,which pr otects them against cor rosion.
Limited braking ef fect on salt-treate dro ads:
R a layer of salt on the brake disks or brakepads
can increase braking dis tances considerably,
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 dep ress the brake pedal at the end
of a journey and af terth est art of a new jour‐
ney
Ne w brake dis ksand brakepads
New brakepads and brake disks only reach their
optimal braking ef fect af ter appro ximately
10 0 km.
Un tilthen, compensate forth ere duced braking
ef fect by applying greater pressure tothe brake
pedal. For saf etyre asons, Mercedes-Benz recom‐ mends
that you on lyha ve brakepads and brake
disks which are appr ovedby Mercedes-Benz
ins talled on your vehicle.
Other brake disks or brakepads may compromise
th e saf ety of your vehicle.
Alw aysre place all brake disks and brakepads on
an axle at the same time. Alw aysfit new brake‐
pads when replacing brake disks.

Note s on aquaplaning
Aq uaplaning can take place once a cer tain
am ount of water has accumulated on thero ad

Obser vethefo llowing no tes during heavy precipi‐
ta tion or in conditions in which aquaplaning may
occu r:
R reduce your speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully

If th e maximum permissible height of thewate r is

aged.
Obser vethefo llowing if you must drive thro ugh
wate r:
R thewate r level of standing water may not be

R you may drive no fasterthan walking pace
R vehicles tr avelling in front, or oncoming vehi‐

The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention to
th e traf fic conditions until braking po wer has
been fully restored.
Note s on driving in mountainous areas
Ve hicles with diesel engines: the operating
saf ety of the diesel engine is guaranteed up toan
ele vation of 2,500 m ab ovesea le vel.Yo u may
exc eed this ele vation for a short time, e.g. in
mountainous terrain. Do not drive continuously at
ele vations ab ove2,500 m. Otherwise, you may
damage the diesel engine.
When driving in mountainous areas, no tethat
engine output, and therefore start-off gradeabil‐
ity, will dec rease with inc reasing ele vation. The

Driving and driving saf
ety sy stems Note
s on driving sy stems and your responsi‐

ur vehicle is equipped with driving sy stems
which assist you in driving, parking and manoeu‐
vring theve hicle. The driving sy stems are only
aids. They are not a substitute foryo u paying
attention toyour sur roundings and do not relie ve
yo u of your responsibility per taining toroad traf‐
fi c la w.The driver is alw aysre sponsible for main‐

st ay ing in lane. Alw ays pay attention tothe tra ffic
and inter vene if necessa ry. Be aware of the limi‐
ta tions rega rding the safe use of these sy stems.
Driving sy stems can neither reduce therisk of
accident if youfa ilto adapt your driving style nor
ove rride the la wsof ph ysics. They cannot alw ays
ta ke into account road, weather or traf fic condi‐
