Make sure there are no vibrations, noises or
unusual handling characteristics when thevehicle
is in motion. This may indicate that the wheels or
tires are damaged. Hidden tire damage could also
be causing the unusual handling characteristics.
If you suspect that a tire is malfunctioning, reduce
your speed immediately and have the tires and
wheels checked at a qualied specialist workshop.

&WWARNINGARNING Risk of injury through damaged
tires
Damaged tires can cause tire pressure loss.
#Check the tires regularlyfor signs of
damage and replace any damaged tires
immediately.
&WWARNINGARNING Risk of hydroplaning due to
insucient tire tread
Insucient tire tread will result in reduced tire
grip.
In heavy rain or slush therisk of hydroplaning
is increased, in particular where speed is not
adaptedto suit the conditions.
#Thus, you should regularlycheck the
tread depth and the condition of the
tread across the entire width of all tires.
Minimum tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
#For safetyreasons, replace the tires
before the legally-prescribed limit forthe
minimum tread depth is reached.
Carry out thefollowing checks on all wheels regu-
larly, at least once a month or as required, for
example, prior to a long journey or driving o-
road:
RCheck the tire pressure (/page 383).
RVisually inspect wheels and tires for damage.
RCheck thevalve caps.
RVisual check of the tire tread depth and the
tire contact surface across the entire width.
The minimum tread depth for summer tires is
âin (3 mm) and for winter tires ãin (4 mm).
Six marks 1show where the bar indicators
(arrow) are integrated into the tire tread. They are
visible once a tire tread depth of approximately
áin (1.6 mm) has been reached.
