& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure , loss of control , collision , serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires. • Incorrect tire pressure and/or underinflation can cause
increased tire
wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and /or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation ,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver 's side 8-pillar.
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring system* can work correctly .
• The use of incorrect tire pressure values can lead to accidents or
other damage . Therefore it is e ssential that the driver observe the
Safety first
& WARNING (co ntinued )
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pres sure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and /overloading can cause heat build-up,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest service station
to check the tire pressure and add air as required .

Driv ing witho ut valve stem caps can cause damage to the t ir e valves.
T o preven t this, a lways make sure th at fa ct o ry insta lled va lve stem
caps on all wheels are s ecure ly m ou nted on t he v alve .

An unstable surface under the jack can cause the vehicle to slip off the
jack. Always provide a firm base for the jack on the ground .
If neces­
sary place a sturdy board or similar support under the jack. On hard,
slippery surfaces (such as tiles) use a rubber mat or similar to prevent
the jack from slipping=> &.

wheel if you do not follow these safety precautions:
-Positioning the jack under the vehicle at any other place than
those indicated above may damage the vehicle or may result in
personal injuries.
- A soft or unstable surface under the jack may cause the
vehicle to slip off the jack. Always provide a firm base for the
jack on the ground. If necessary, use a sturdy board under the
jack.
- On hard, slippery surface (such as tiles) use a rubber mat or
similar to prevent the jack from slipping.
• To help prevent injury to yourself and your passengers:
- Do not raise the vehicle until you are sure the jack is securely
engaged.

& WARNING (conti nu ed )
• The engine compartment of any motor veh icle is a potentially
hazardous area . Never reach into th e area around or touch the
radiator fa n. It is temperature controlled and can switch on
s uddenly -even when the engine is off and the ignition key has
been remo ved. The radiator fan switches on autom atically when
the coolant rea ches a certain temperature and will continue to run
until the coolant tempe rature drops.
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it i s neces sary
to work unde rne ath the vehicle. The jac k supplied with the vehicle
is not adequate for thi s purpose and could collap se cau sing
serious personal injury.
• If you must work underneath the vehicle w ith the wheels on
the ground , always ma ke sure the vehicle is on level ground , th at
the whe els are alway s securely blocked and that the engine cannot
be started .
