WARNING
Make sure tha tother road user sare not
endang ered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing
atrailer,
yo um ust select shift range 1,2or 3in good
time.
i This als oapplies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Heavy and light loads G
WARNING
Never depress the brak epeda lconti nuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by apply ingc onstant slight
pedal pressure. This causes the brake system
to overheat, increases the brakin gdistance
and can lead to the brakes failing completely.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately ,but
drive on for ashort while. This allow sthe air-
flo wtoc ool the brakes mor equickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surface If driving in heavy rain for
aprolonged period
of time without braking, there may be a
delayed reaction from th ebrake swhen brak-
ing for the first time. This ma yalso occur after
the vehicle has been washed. You have to depress the brake pedal more
firmly. Maintain
agreater distance from the
vehicl einfront.
After driving on awet road or havin gthe vehi-
cle washed, brake firml ywhile paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protectin gthem against corro-
sion.
Limited braking perfo rmance on salt-
treated roads G
WARNING
The layer of salt on the brake discs and the
brake pads/linings may cause adelay in the
braking effect ,resultin ginas ignifican tlyl on-
ger brakin gdistance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully, without put-
ting other road users at risk, when you are
drivin gons alted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain agreater distance to th evehicle
ahead and driv ewith particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linin gs G
WARNING
New brak epads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you shoul dcompensate
for the reduced brakin geffect by applying
greate rpressure when braking .This also
applies after the brake discs or the brake
pads/linings hav ebeen replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brak epads/linings Driving tips

etrac tion G
WARNING
Whereas the vehicle can be fully controlle dat
ac ertain speed on dry roads, you must reduce
your speed on wet or icy roads to achiev ethe
sam eroad safety. You coul dotherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), athin fil mofw ater rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Driv ewith particular care in
such weather conditions. Driving on wet roads
Aqua planing If water ha
saccumulate dtoacertain depth
on the road surface, ther eisadanger of aqua-
planing occurring, even if:
R you are driving at low speeds.
R the tyres have adequate tread depth.
For this reason, do not drive in tyre ruts, and
brake carefully.
Driving on flooded roads If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permissible still water depth
depends on the vehicle equipment.
R you should drive no faster than at walking
pace. !
Bear in mind that vehicles travellin gin
front or in th eopposite direc tion create
waves. This ma ycause the maximum per-
missible water depth to be exceeded.
Thes enotes must be observed under all
cir cums tances. You could othe rwise dam-
age the engine, the electronics or the trans-
mission.

Important safet ynotes G
WARNING
Driv eslowly in rough terrain with which you
are unfamiliar. This will allow you to detect
unexpected obstacles more easily and, there-
fore, to reduce the risk of an accident.
Do not make U-turns on mountain roads. Oth-
erwise, the vehicle could tip over. If aslope is
too steep for the vehicle, drive back in reverse
gear.
Do not drive at an angle up steep inclines.
Otherwise, the vehicle could tip over. If you
drive up asteep incline at an angle and the
vehicle threatens to overturn, stee rinto the
line of fall immediately.
Never allo wthe vehicle to roll backwards. The
brakin geffect of the engine canno tbeu tilised
in neutral. If you only use the service brake,
you could los econtrol of the vehicle. G
WARNING
Grains of sand, particles of dirt and other
abrasiv ematerials can enter the brake sys-
tem. This can lead to excessive wear and
unpredictable braking efficiency.
After the brakes have been expose dtodirty
conditions ,have them checked and cleaned
at aq ualified specialist workshop ,e.g. a
Mercedes-Benz Service Cent re.O therwise,
there is arisk that braking power may be
insufficient in the event of an emergency, or
that the braking effec tmay be unpredictable. G
