Traction
Traction is the result of friction between the
tires and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximu mpermissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are
distributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 000Bin
(1.6 mm) has been reached.
Distribution of the vehicle occupants
The distribution of vehicle occupants over
designated seat positions in avehicle.
Maximum permissible payload weight
Nominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Flat tire
General notes
Your vehicle may be equipped with Premium
tire sealant or with a spare wheel. The spare
wheel is under the vehicle at the rear
(Y page 308). The Premium tire sealant is
located in the stowage compartment in the
right-hand door sill (Y page 264).
You can find information on changing/
mounting wheels in the "Wheel change"
section (Y page 303).
When you replace a tire, we recommend that
you also replace the tire valve. Please observe
the safety-relevant information on tire valve
(Y page 280). Vehicle preparation
X Stop the vehicle as far away as possible
from traffic and on a level, firm and non-slip
surface.
X Switch on the hazard warning lamps if the
vehicle poses a hazard to passing vehicles.
X Turn the fron twheels to the straight-ahead
position.
X Move the selector lever of the automatic
transmission to position P.
X Switch off the engine.
X Passengers should leave the vehicle. Make
sure that the passengers are not
endangered as they do so.
X Make sure that no one is near the danger
area while a wheel is being changed.
Anyone who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Place the warning triangle or warning lamp
at a suitable distance.
Observe legal requirements. Using Premium tire sealant
Using Premium tire sealant You can use Premium tire sealant to seal
punctures of up to 0.23 in (6 mm), particularly
those in the tire tread. Tire sealant can be
used at outside temperatures down to
002722 ‡ (002730 †).

WARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown
assistance, as it is unable to seal the tire
properly:
R there are cuts or punctures in the tire larger
than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tire pressures
or on a flat tire.
There is a risk of an accident. Flat tire

recommended tire pressure. You will find a
table of recommended tir epressure on the
Tire and Loading Information placard 10

Tire pressure of 300 kPa (3.0 bar/
43.5 psi) not reached G
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.
