If you turn off the engine using the SmartKey and

remove the SmartKey from the starter
switch
or

open a door
the transmission will shift to park positionP
automatically.
Keep in mind that turning off the engine with the
SmartKey alone only will automatically shift the
transmission to neutral positionN.

If you turn off the engine using the KEYLESS-GO
start/stop button and open the driver’s or pas-
senger door, the transmission will shift to park
positionP automatically.
Keep in mind that turning off the engine using
the KEYLESS-GO start/stop button alone only
will automatically shift the transmission to

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.The hill start assist system is inactive

when starting off on a level road or
downhill grades

with the transmission in neutral
position N

malfunction
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 a electronic parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the electronic parking brake
in addition to shifting to park positionP.

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

Cruise control (page 405) and
DISTRONIC Plus*(
page 411), with
which the vehicle can maintain a preset
speed.

ABC (page 429) adjusts the vehicle
suspension characteristics automati-
cally and control the vehicle level.

Parktronic* (page 431) and
Park Assist* (
page 435), which serve
as a parking assistant.

Dynamic Rear View Monitor*
(
page 439) is an electronic and
visual parking aid.

Night View Assist* (page 446) illumi-
nates the road with infrared light in
addition to the normal headlamps.
For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, ESP
® and
PRE-SAFE® Brake*, see “Driving safety
systems” (
page 64).
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
remain 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
advisable to travel at a constant 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 constant 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
driving 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.
