Braking
Important safety notes
G WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
! On long and steep gradients, you must
reduce the load on the brakes by shifting to
a lower gear in good time. This allows you to
take advantage of the engine's braking
effect. For this, you need to have selected
manual drive program M . This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive
program M is temporarily activated: the auto-
matic transmission may switch to the last
active automatic drive program E or S . The
automatic transmission may shift to a higher
gear. This can reduce the engine's braking
effect.
Heavy and light loads
G WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident. Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
Wet roads If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm up
the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance. R
In order to prevent any salt build-up, apply
the brakes occasionally while paying atten-
tion to the traffic conditions. R
Carefully depress the brake pedal and the
beginning and end of a journey. R
Maintain a greater distance to the vehicle
ahead. Driving tips 177

Driving tips
Driving and parking

In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
consult a qualified specialist workshop.
The vehicle is only designed for easily nego-
tiable off-road terrain and poor road surfaces.
When driving off-road, substances such as
sand, mud and water or water mixed with oil
may get into the brakes. This could result in a
reduced braking effect or in total brake failure
and also in increased wear and tear. The brak-
ing characteristics change depending on the
material ingressing the brakes. Clean the
brakes after driving off-road. If you detect a
reduced braking effect or grinding noises,
have the brake system checked in a qualified
specialist workshop as soon as possible.
Adapt your driving style to the different brak-
ing characteristics.
Driving off-road increases the likelihood of
damage to the vehicle, which, in turn, can lead
to failure of the mechanical assembly or sys-
tems. Adapt your driving style to suit the ter-
rain conditions. Drive carefully. Have damage
to the vehicle rectified immediately at a quali-
fied specialist workshop.
Do not switch to transmission position N
when driving off-road. If you try to brake the
vehicle using the service brake, you could
lose control of the vehicle. If the gradient is
too steep for your vehicle, drive back down in
reverse gear.

Traveling uphill
Approach/departure angle
G WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a
risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. R
Observe the warnings for off-road driving
( Y
page 180). R
Follow the line of fall when driving on slopes
and steep inclines. R
Before driving on extreme uphill and down-
hill gradients, select the off-road program
( Y

Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle's own impetus to
travel over the brow.
This style of driving prevents: R
the vehicle from lifting off the ground on the
brow of a hill R
the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly. R
Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip

ling steep downhill gradients. Driving tips 183
Driving and parking Z

If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS ( Y
page 190).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it
is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is
set using the control on the cruise control
lever. When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion P if: R
the driver's seat belt is not fastened and the
driver's door is open. R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is not sufficient.
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position P automatically.
