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 (1.6 mm), at which point
the tire is considered worn and should be
replaced.
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).
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:
ț Keep right foot on brake pedal.
ț Firmly depress parking brake pedal.
ț Move the gear selector lever to
position
P (manual transmission: first or
reverse gear).
ț Slowly release brake pedal.
ț When parked on an incline, turn front
wheel against curb.
ț Turn the SmartKey to starter switch
position
0.
ț Take the SmartKey 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
Although the applicable federal motor vehi-
cle safety laws consider a tire to be worn
when the tread wear indicators (TWI) be-
come visible at approximately
1
/
16
in
(1.6 mm), we recommend that you do not al-
low your tires to wear down to that level. As
tread depth approaches
1
/
8
in (3 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.
