Tires
Treadwear 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 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 Turn the SmartKey in the starter switch
to position 0 and remove the SmartKey
from the starter switch.
ț Take the SmartKey and lock vehicle
when leaving.
!
Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move gear selector lever to position P.
In addition, when parking on hills turn
front wheel towards the road curb.
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 Light Truck 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.
