Wa r n i n g !
In order to avoid distraction which could lead to an
accident, system settings should be entered with
the vehicle at standstill and systems should be
operated by the driver only when traffic conditions
permit. Always pay full attention to traffic
conditions first before operating system controls
while driving. Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is covering a
distance of 50 feet (approximately14 m) every
second.
Wa r n i n g !
Any alterations made to electronic components can
cause malfunctions.The radio, cassette deck, CD changer
1 and
telephone

266 Driving instructions
Te ch n i c a l
data Instruments

Specified tire pressures must be maintained. This
applies particularly if the tires are subjected to high
loads (e.g. high speeds, heavy loads, high ambient
temperatures).
Aq uaplaning
Depending on the depth of the water layer on the road,
aquaplaning may occur, even at low speeds and with
new tires. Reduce vehicle speed, avoid track grooves in
the road and apply brakes cautiously in the rain.Tire traction
The safe speed on a wet, snow covered or icy road is
always lower than on a dry road.
You should pay particular attention to the condition of
the road whenever the outside temperatures are close to
the freezing point.
We recommend M+S rated radial-ply tires for the winter
season for all four wheels to insure normal balanced
handling characteristics. On packed snow, they can
reduce your stopping distance as compared with
summer tires. Stopping distance, however, is still
considerably greater than when the road is not snow or
ice covered.
Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire or driving at high speed with a flat tire will
cause excessive heat build-up and possibly a fire.
Wa r n i n g !
If ice has formed on the road, tire traction will be
substantially reduced. Under such weather
conditions, drive, steer and brake with extreme
caution.

The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TM compatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation system.Follow the manufacturer’s instructions for
installation of special child seats.The passenger front airbag will not deploy only if
the ü indicator lamp remains illuminated.Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart
TM restraint to transport children
on the front passenger seat until the system has
been repaired.

warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.
If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment on the right hand side.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight as indicated by the label on
the driver’s door latch post). Overloading the tires
can overheat them, possibly causing a blowout.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clot hin g. In cas e i t d oes , i mm ed ia tely f lus h a f fected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc.
