GWARNIN G
A discharged battery can freez eat tempera-
tures belo wfreezing point. When jump-start -
ing th evehicl eor charging th ebattery, gase s
can escape from th ebattery. Ther eis aris kof
an explosion .
Allow th efrozen battery to thaw out before
charging it or jump-starting .
If th eindicator/warning lamp sdo no tligh tup in
th einstrumen tcluste rwhen temperatures are
low, it is probably because th edischarged bat -
tery has frozen .Should this be th ecase, do no t
jump-start th evehicl eor charge th ebattery. The
servic elife of athawed battery may be shorter.
Start-up behavior may deteriorate, in particular
at low temperatures .Hav eth ethawed battery

Maintenance and care

Regular wheel and tire checks
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two weeks,
as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of tire
pressure. Pay particular attention to damage
such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 249). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not install
anything onto the valve other than the standard
valve cap or other valve caps approved for your vehicle by dealers listed on the inside of the
front cover. Do not install any other valve caps
or systems, e.g. tire pressure monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if ne
cessary (Ypage 251).
The service life of tires depends on various fac-
tors, including the following:
RDriving style
RTire pressure
RMileage
Tire tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Bar marking :for tread wear is integrated into
the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth is
approximately áin. (1.6 mm). If this is the
case, the tire is so worn that it must be replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount tires of the correct size onto the
wheels.
RBreak in new tires at moderate speeds for the first 65 miles (100 km).
