Tires
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately
1 /
16
in (1.6 mm), at which point the
tire is considered worn and should be re-
placed.
The treadwear indicator appears as a solid
band across the tread.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subject to high loads (e.g. high
speeds, heavy loads, high ambient temper-
atures).
ț Slowly release brake pedal.
ț When parked on an incline, turn front
wheels towards the road curb.
ț Turn the SmartKey in the starter switch
to position 0 and remove.
ț Take the SmartKey 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 undercar-
riage for possible damage. If the vehicle or
tires appear unsafe, have the vehicle towed
to the nearest Mercedes-Benz Center or tire
dealer for repairs.
Warning!
G
Although the applicable federal motor vehi-
cle safety laws consider a tire to be worn
when the treadwear 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 (3.0 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.
