WARNING
If the specified tire pressure is not reached,
the tire is too severely damaged.T he tire
sealant cannot offer assistance with a flat tire in this case. Damaged tires as well as tire
pressure that is too low can impair the braking
and driving characteristics. There is a risk of
an accident.
Do not drive any further. Notify a qualified
specialist workshop.

WARNING
At ire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum speed for a tire sealed with tire
sealant is 50 mph (80 km/h).
The "max. 50 mph" (80 km/h) sticker must
be affixed within the driver's field of vision.

X Clean the valve core extractor with clean
water.
X Remove angled valve adapter 0006from valve

and/or valve tool, warning triangle and
warning lamps in the vehicle.
X Pull away immediately.
This enables the tire sealan tto distribute
inside the tire and create a more effective
seal.
X After driving for approximately 3 minutes,
stop the vehicle at a suitable location, e.g.
at a car park or gas station.
X Check the tire pressure again.
The tire pressure must be at least
300 kPa (3.0 bar/43.5 psi). G
WARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
i The Mercedes-Benz Service24h
telephone numbers can be found on a
sticker in the driver's door entrance area
and in the vehicle Maintenance Booklet.
i If you check the tire pressure with the tire
inflation compressor, connect angled valve
adapter 0006on tire inflation compressor
hose 0026directly to the tire valve. The tire
pressure will increase when you switch the
tire inflation compressor on. You can
reduce the tire pressure by opening the
pressure release screw on pressure gauge
0023.
If the tire pressure is still at least 300 kPa
(3.0 bar/43.5 psi):
X If possible, inflate the tire to the
recommended tire pressure (Y page 278).
X Drive to the nearest qualified specialist
workshop as soon as possible and have the
tire and tire sealant 0019replaced. Changing wheels
Rotating the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of
accident.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed at a qualified
specialist workshop.
Always observe the instructions and safety
notes in the "Mounting awheel" section
(Y page 303).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of rotation.
Clean the contac tsurface softhe wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressure and
reactivate the tire pressure monitor if
necessary. 302

Raising the vehicle G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate
jacking point of the vehicle. The base of the
jack must be positioned vertically, directly
under the jacking point of the vehicle. G
WARNING
On uphill and downhill slopes, the jack could
tip over with the vehicle raised. There is a risk
of injury.
Do not change wheels on uphill or downhill
gradients. Notify a qualified specialist
workshop.
! Only position the jack on the jacking
points intended for this purpose. You could
otherwise damage the vehicle.
Observe the following when raising the
vehicle:
R When raising the vehicle, only use the jack
specifically approved for your vehicle.
R the vehicle's jack is intended only to raise
the vehicle for a short time when changing
a wheel. It is not suited for performing
maintenance work under the vehicle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
R make sure the distance between the
underside of the tires and the ground does
not exceed 1.2 inches (3 cm).
R never place your hands or feet under the
raised vehicle.
R never lie under the raised vehicle.
R never start the engine when the vehicle is
raised.
R never open or close a door when the vehicle
is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. 304
