42 Getting startedDriving
Place the belt over your shoulder.

Push latch plate2 into buckle3 until it
clicks.

If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
Belt outlet height adjustment
1Release button

Press release button1 and move the
seat belt height adjuster upward or
downward.Proper 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 or pass under the
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.


Each seat belt should never be used 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.


Check your seat belt during travel to
ensure that it is properly positioned.


Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing
bulky clothing, such as winter coats,
when traveling in the vehicle.

73 Safety and Security
Driving safety systems
Driving safety systems
In this section you will find information on
the following driving safety systems:

ABS (A
ntilock B
rake S
ystem)


BAS (B
rake A
ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)


SBC (S
ensotronic B
rake C
ontrol)
ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
If the ABS activates during braking, the
ESP warning lamp v in the instrument
cluster dial flashes. Because of the SBC
brake system, you will not feel any pulsa-
tion in the brake pedal.
iIn winter operation, the maximum ef-
fectiveness of the ABS and the ESP is
only achieved with winter tires (M + S
tires), or snow chains as required.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, ESP and SBC cannot reduce
this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

155 Controls in detail
Automatic transmission
Program mode selector switch
1Program mode selector switch
S Standard For regular driving
W Winter For winter driving

Press the program mode selector
switch repeatedly until the letter of the
desired shift program appears in the
speedometer display field
(page 121).
Select
Wfor winter driving:


The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.


Traction and driving stability are im-
proved on icy roads.


Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.


The power transmission ratio for se-
lector lever positionR changes de-
pending on the program mode
selected (
W or
S).
Warning!
G
When leaving the vehicle always remove the
key from the starter switch, take the Smart-
Key with KEYLESS-GO* (if so equipped) with
you and lock the vehicle. Do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Children could
move the selector lever from positionP,
which could result in an accident or serious
injury.
!Never change the program mode when
the selector lever is out of positionP. It
could result in a change of driving char-
acteristics for which you may not be
prepared.

253 Operation
Driving instructions
The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subjected to high loads (e.g. high
speeds, heavy loads, high ambient temper-
atures).
Aquaplaning
Depending on the depth of the water layer
on the road, aquaplaning may occur, even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
rain.
Tire traction
The safe speed on a wet, snow covered or
icy road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.
Mercedes-Benz recommends M+S rated
radial-ply tires for the winter season for all
four wheels to insure normal balanced
handling characteristics. On packed snow,
they can reduce your stopping distance
compared to summer tires. Stopping dis-
tance, however, is still considerably great-
er than when the road is not covered with
snow or ice. Exercise appropriate caution.
Warning!
G
Do not allow your tires to wear down too far.
As tread depth approaches
1⁄16
in (1.5 mm),
the adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire or driving at high
speed with a flat tire will cause excessive
heat build-up and possibly a fire.
Warning!
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.

254 OperationDriving instructionsTire speed rating
Your vehicle is factory equipped with
"H"-rated tires, which have a speed rating
of 130 mph (210 km / h).
An electronic speed limiter prevents your
vehicle from exceeding the speed rating.
Regardless of the tire rating, local speed
limits should be obeyed. Use prudent driv-
ing speeds appropriate to prevailing condi-
tions.
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move selector lever to position N or in
case you have a manual transmission, de-
clutch. Try to keep the vehicle under con-
trol by corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
We therefore recommend depressing the
brake pedal periodically when traveling at
length on salt-strewn roads.
This can bring road salt impaired braking
efficiency back to normal. A prerequisite
is, however, that this be done without en-
dangering other drivers on the road.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed while observing the
safety rules in the previous paragraph.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and re-
sulting in personal injury and possible death.
iFor more information on driving with
snow chains, see "Snow chains"
(page 274).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
