Occupant safety
AirbagsWarning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, or side (side impact airbags) impacts
which may cause significant injuries. How-
ever, no system available today can totally
eliminate injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma or other breathing trouble. To avoid this,
you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and passenger to always be in a prop-
erly seated position and to wear your seat
belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and ensure it is properly posi-
tioned on your body.
Since the airbag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:

Sit properly belted in an upright position
with your back against the seat back-
rest.


Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least ten
inches (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.


Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.

ABS
The Antilock Brake System (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.
The - malfunction indicator lamp in the
instrument cluster (
page 20) lights up
when you turn the key in the steering lock
to position2. It goes out when the engine
is running.
iIn winter operation, the maximum ef-
fectiveness of the ABS and 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 and ESP 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.

Manual transmissionInformation on driving with a manual trans-
mission is found in the “Getting started”
section (
page 40).
Do not exceed the maximum speed in the
individual gears. Refer to tachometer
(
page 90) for engine speeds.
Shifting into reverse
Stop the vehicle completely.

Pull gearshift lever up and shift in
Rreverse.
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or re-
verse gear and parking brake engaged is
dangerous. Also, when parked on an incline,
an engaged first or reverse gear alone may
not prevent your vehicle from moving, possi-
bly hitting people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 47).
When parked on an incline, turn front wheels
towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could move the gearshift
lever, which could result in an accident
and/or serious injury.
On slippery road surfaces as well as high en-
gine speeds, never downshift in order to ob-
tain braking action. This could result in drive
wheel slip and reduced vehicle control. Your
vehicle’s ABS will not prevent this type of
loss of control.
!Downshifting gears leading to overrev-
ving the engine can result in engine
damage that is not covered by the
Mercedes-Benz Limited Warranty.
Never hold the vehicle stopped on a hill
by using the clutch pedal. The clutch
may be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.
Do not exceed the engine speed limits
(page 90).

General notes on CD mode
Should excessively high temperatures oc-
cur while the audio system is in CD mode, TEMP HIGH
will appear in the display and
muting will take place. The unit will then
switch back to radio mode until the tem-
perature has decreased to a safe operating
level.
Should excessively low temperatures oc-
cur while the audio system is in CD mode,
TEMP LOW
will be displayed, but the CD will
still be played. It will be sensitive to skip-
ping if you are driving over rough roads.
Handle CDs carefully to prevent interfer-
ence during playback.
Avoid fingerprints and dust on CDs. Do not
write on the CDs or apply any label to the
CDs.
Clean CDs from time to time with a com-
mercially available cleaning cloth. No sol-
vents, anti-static sprays, etc. should be
used. Replace the CD in its container after use.
Protect CDs from heat and direct sunlight.
Only use CDs which bear the label shown
and that conform to the compact disc dig-
ital audio standard (IEC 60908). You can
therefore only use CDs with a maximum
thickness of 1.3 mm.
!Your CD drive has been designed to
play CDs which correspond to the EN
60908 standard. If you insert thicker
data carriers, e.g. ones that have data
on both sides (one side with DVD data,
the other side with audio data), they
cannot be ejected and will damage the
drive.
Use of CDs which do not meet this
standard may cause damage to the CD
changer. Do not play single-CDs
(80 mm) with an adapter.
