D Neutral
Do not shift the transmission to N
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brakes will allow you to
move the vehicle freely, e.g. to push
it or tow it.
If ESP ®
is deactivated or faulty: shift
the transmission to position N if the
vehicle is in danger of skidding, e.g.
on icy roads.
If you switch the engine off with the
transmission in position R or D , the
automatic transmission shifts to N
automatically.
! Rolling in neutral N can damage
the drive train.
: Drive
The automatic transmission changes
gear automatically. All forward gears
are available.
Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D . This automatic gear shifting
behavior is determined by: R
the selected drive program R
the position of the accelerator pedal R
the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear: R
little throttle: early upshifts R
more throttle: late upshifts Kickdown Use kickdown for maximum acceleration. X
Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed. X
Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free Shifting the transmission repeatedly between
gears D and R may help to free the vehicle if it
has become stuck in slush or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when
shifting back and forth. To shift back and forth
between transmission positions D and R , move
the DIRECT SELECT lever up and down past the
point of resistance.
Towing a trailer X
Drive in the middle of the engine speed range
on uphill gradients. X
Depending on the uphill or downhill gradient,
use the left-hand steering wheel paddle
shifter ( Y
page 150) to select a lower gear,
even if cruise control or Distance Pilot
DISTRONIC are activated.
Drive programs
Slippery drive program The Slippery drive program has the following
characteristics: R
reduced engine and transmission settings for
optimum propulsion on slippery or snow-cov-
ered roads. R
optimized ESP ®
stability control on slippery or
snow-covered roads. R
the vehicle has improved driving stability on
slippery or snow-covered roads, for example.Automatic transmission 149
Driving an d parking Z

This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, a
drive wheel may not turn for some time, e.g.
on a slippery road surface. This could cause
damage to the drive train. This type of damage
is not covered by the Mercedes-Benz war-
ranty.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light pres-
sure to the pedal. This results in excessive and
premature wear to the brake pads.
Use the left-hand steering wheel paddle shifter
to shift into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
This also applies if you have activated cruise
control, the speed limiter or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
that less braking will be required to maintain the
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
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 airflow 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 then 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 vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance. R
Brake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so. R
Carefully depress the brake pedal and the
beginning and end of a journey. R
Maintain a greater distance to the vehicle
ahead.
Servicing the brakes
! The brake fluid level may be too low, if: R
if the red brake warning lamp lights up in
the instrument cluster and R
you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
! A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe-
cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system.
! Because ESP ®
is an automatic system, the
engine and ignition must be switched off
(SmartKey in position 0 or 1 or Start/Stop
button in position 0 or 1 ) when the electricDriving tips 165

Off-road fording
! Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and other assemblies.
! Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment. R
Establish how deep the water is and the char-
acteristics of the body of water before ford-
ing. R
Select the highest possible vehicle level. R
Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter. R
Avoid high engine speeds. R
Enter and exit the water at a flat place and at
a steady walking pace. R
Drive slowly and at an even speed through the
water. R
Ensure that a bow wave does not form as you
drive. R
Do not stop and do not switch off the engine.
Water offers a high degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in the water. R
Clean any mud from the tire tread after ford-
ing. R
Apply the brakes to dry them after fording.
Always observe the fording depth values
( Y
page 385).
Winter driving
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.
G DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or
Distance Pilot DISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed: X
Shift the transmission to position N .
When driving in snow with or without snow
chains, select driving program Slippery
( Y
page 145).
i Vehicles with a diesel engine: do not
cover the radiator, e.g. with a protective
cover. The measuring function of the on-
board diagnosis system may otherwise pro-
vide inaccurate values. Some of these values
are required by law and must therefore always
be accurate.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. You should pay
special attention to road conditions when tem-
peratures are around the freezing point.
For more information on driving with snow
chains, see ( Y
page 348).
For more information on driving with summer
tires, see ( Y
page 348).

Cruis e contro l
General notes
Cruise contro l maintain s a constant road speed
fo r you. It brake s automatically in order to avoid
exceedin g th e set speed. You mus t selec t a
lowe r gear in goo d time on lon g and steep down -
hill gradients, especially if th e vehicle is lade n or
towin g a trailer . By doin g so, you will mak e use of
th e braking effect of th e engine. Thi s relieves th e load on th e brake system and prevents th e
brake s from overheatin g and wearin g to o
quickly.
Use cruise contro l only if road and traffic con-
dition s mak e it appropriat e to maintain a steady
speed fo r a prolonged period. You can stor e any
road speed abov e 20 mph (30 km/ h) .
i Cruise control should not be activated when
driving off-road.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traff ic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle spee d, for braking in
good time and for staying in your lane.
Do not use cruise control: R
in road and traffic conditions whic h do not
allow you to maintain a constant spee d, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driv er of the speed store d.
