390 Controls in detailFastening the seat beltsProper use of seat belts

Do not twist the belt when fastening.


Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the belt under your
arm.


Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.


Place the seat backrest in a nearly up-
right position.


Never use a seat belt for more than one
person at a time.


Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant restraint, toddler restraint, or
booster seat always follow the child
seat manufacturer’s instructions.


Check your seat belt during travel to
make sure that it is properly posi-
tioned.


Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.For more information, see “Seat belts”
(
page 53).
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz
Center.

Automatic transmission
Transmission positions
The current transmission position appears
in the multifunction display.
1Current transmission position!
If the current transmission position does not
appear in the multifunction display due to a
malfunction, for example, make sure that the
automatic transmission is in the desired position
by carefully driving off with the transmission in
drive positionD and program modeS
(
page 427) selected. Do not limit the gear
range.
Effect
ì
Park position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always engage the elec-
tronic parking brake in addition
to shifting into park positionP to
secure the vehicle.
If the vehicle’s electrical system
is malfunctioning, the automatic
transmission could remain
locked in park positionP.
Have the vehicle checked as
soon as possible by an autho-
rized Mercedes-Benz Center.
!
SmartKey:
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.
!
KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO
start/stop button and open a door, the transmis-
sion 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
neutral positionN.

In the following cases you cannot activate
the cruise control:


when you brake


the vehicle is secured with the elec-
tronic parking brake


when the automatic transmission is set
to park positionP, reverse gear R, or
neutral positionN


when ESP
® is switched off
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.
i
The vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.

Setting a higher speed
You can increase the set speed in two
ways.Adjustment in 1 mph (Canada: 1 km/h)
increments

Briefly lift the cruise control lever up to
the resistance point in direction of
arrow1 (
page 438).

Release the cruise control lever.
The vehicle speed increases in incre-
ments of 1 mph (Canada: 1 km/h).
i
The cruise control switches off automatical-
ly when


you step on the brake pedal


the vehicle is secured with the electronic
parking brake
In this case, the cruise control speed seg-
ments in the multifunction display will go out
and no warning sounds.


the vehicle speed is below 20 mph
(30 km/h)


the ESP
® is in operation or switched off with
the ESP® switch (
page 72)


you set the automatic transmission to neu-
tral positionN while driving
The cruise control speed segments in the
multifunction display will go out and an
acoustic warning sounds.
Observe additional messages in the
multifunction display that may appear.
!
Setting the automatic transmission to neu-
tral positionN while driving cancels the cruise
control. However, the automatic transmission
should not be set to neutral positionN while driv-
ing except to coast when the vehicle is in danger
of skidding (e.g. on icy roads).
i
Depressing the accelerator pedal does not
deactivate the cruise control. After a brief accel-
eration (e.g. for passing), the cruise control will
resume the last set speed.Warning!
G
If you increase the set speed, keep in mind
that it may take a brief moment until the ve-
hicle has made the necessary adjustments.
Increase the set speed to a value that the
prevailing road conditions and legal speed
limits permit. Otherwise, sudden and unex-
pected acceleration of the vehicle could
cause an accident and/or serious injury to
you and others.
i
The set speed value is increased in 1 mph
(Canada: 1 km/h) increments each time you lift
the cruise control lever up to the resistance
point.
