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

Cruise control, with which the vehicle
can maintain a preset speed.

Hill start assist system which helps you
to start off smoothly on a hill.
For information on the ABS, Adaptive
Brake, BAS, EBP, ESP
®, and 4MATIC, see
“Driving safety systems” (
page 59).
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 steady speed.

The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow
safe driving at a steady speed.

The use of the cruise control can be
dangerous 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
operated if the driver is fully aware of the
previously 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.

Opening and closing power tilt/sliding
sunroof
Warning!G
When closing the tilt/sliding sunroof, make
sure there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof is blocked while
closing and reopens, it can be closed with
greater force if you pull the switch to the re-
sistance point in the direction indicated by
arrow
3 within 2 seconds.
If the tilt/sliding sunroof is blocked again
and reopens, you can close it with deactivat-
ed obstruction sensor function by pulling
the switch again to the resistance point in
the direction indicated by arrow
3 within 2
seconds.
When closing the tilt/sliding sunroof with
the obstruction sensor function deactivated,
make sure no one can become trapped, as
this could result in serious or fatal injuries.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the switch or, if the switch
was moved past the resistance point and re-
leased, by moving the switch in any direc-
tion.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
!To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.
Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
!Please keep in mind that weather conditions
can sometimes change rapidly. Make sure to
close the tilt/sliding sunroof when leaving the
vehicle. If water enters the vehicle interior, vehi-
cle electronics could be damaged which is not
covered by the Mercedes-Benz Limited
Warranty.

accident, the glass may shatter. This may re-
sult in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening.
Such an opening also presents a potential
for injury for occupants wearing their seat
belts properly as entire body parts or por-
tions of them may protrude from the pas-
senger compartment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to

Programming integrated remote con-
trol
Step 1:
Switch on the ignition (page 82).
Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when indicator lamp1 be-
gins to flash after approximately
20 seconds (do not hold the button for longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.
Step 3:
Hold the end of hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.Indicator lamp1 will flash, first slowly
and then rapidly.
Step 5:
After indicator lamp1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe indicator lamp1.
If indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or4) is pressed and re-
leased.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health.
All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
iIndicator lamp1 flashes immediately the
first time the signal transmitter button is pro-
grammed. If this button has already been pro-
grammed, the indicator lamp will only start
flashing after 20 seconds.
