Automatic transmission
Stopping
When you stop briefly, e.g. at traffic lights:
Leave the transmission in gear.
Hold the vehicle with the brake.
When you stop for a longer period of time
with the engine idling and/or on a hill:
Engage the electronic parking brake.
Shift into park positionP.
Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:
Control the vehicle speed by gradually
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.Rocking the vehicle
Rocking the vehicle by shifting between
drive positionD and reverse gearR can
help free a vehicle stuck in mud or snow.
The engine control system of this vehicle
electronically limits shifting between drive
positionD and reverse gearR to very low
speeds, i.e. approximately 5 mph
(9 km/h). To shift between drive
positionD and reverse gearR, move the
gear selector lever past the resistance
point up or down.
Working on the vehicleHill start assist system
On uphill grades with a gradient angle of
more than 5°, the hill start assist system
maintains the pressure in the brake sys-
tem for approximately 1 second after you
have released the brake pedal. Therefore,
you can start off smoothly without the
vehicle moving immediately after releasing
the brake pedal.
Warning!G
When working on the vehicle, engage the
electronic parking brake and shift to park
positionP. Otherwise the vehicle could roll
away.
Warning!G
The hill start assist system is not designed
to function as an electronic parking brake
and does not prevent the vehicle from mov-
ing when parked on an incline.
Always engage the electronic parking brake
in addition to shifting to park positionP.

Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control (page 419) and
DISTRONIC Plus*(
page 424), with
which the vehicle can maintain a preset
speed.

Airmatic (page 440) (S 550 only) and
ABC* (
page 442) adjust the vehicle
suspension characteristics automati-
cally and control the vehicle level.

Parktronic* (page 444) and Park As-
sist* (
page 448), which serve as a
parking assistant.

Dynamic Rear View Monitor*
(
page 453) is an electronic and visu-
al parking aid.

Night View Assist* (page 461) illumi-
nates the road with infrared light in ad-
dition to the normal headlamps.

Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the cruise control at
any speed over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
Warning!G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always re-
main responsible for the vehicle’s speed and
for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a steady speed.

The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a steady speed.

The use of the cruise control can be dan-
gerous on slippery roads. Rapid changes
in tire traction can result in wheel spin
and loss of control.

Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Warning!G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses when the cruise con-
trol engages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
– your foot could become caught.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
iThe vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.
