Tires
Tread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1
⁄
16
in (1.5 mm), at which point the
tire is considered worn and should be re-
placed.
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 extreme operating condi-
tions (e.g. high speeds, heavy loads, high
ambient temperatures).
Warning! G
To reduce the risk of personal injury as a re-
sult of inadvertent vehicle movement, be-
fore turning off the engine and leaving the
vehicle always:
ț Keep right foot firmly on brake pedal.
ț Firmly depress parking brake pedal.
ț Move the selector lever to position P.
ț Slowly release brake pedal.
ț When parked on an incline, turn front
wheels towards the road curb.
ț Turn the key to starter switch position 0
and remove, or press KEYLESS-GO*
start/stop button (vehicles with
KEYLESS-GO*).
ț Take the key or the SmartKey with
KEYLESS-GO* (if so equipped) with you
and lock vehicle when leaving.
Warning! G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.
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.
