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 †).
G
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

Do not drive any further. Contact a qualified
specialis tworkshop. G
WARNING
The tire sealant is harmful and causes
irritation. It must not come into contact with
your skin, eyes or clothing or be swallowed.
Do not inhale TIREFIT fumes. Keep tire sealant
away from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
R Rinse off the tire sealant from your skin
immediately with water.
R If the tire sealant comes into contact with
your eyes, immediately rinse them
thoroughly with clean water.
R If tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tire sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
In addition, observe the manufacturer's
safety instructions on the sticker on the tire
inflation compressor and on the sticker on the
tire sealant bottle.
The tire sealant is water-soluble. If tire sealant
escapes, you can wash it off with water.
i Have the tire sealant replaced every
8y ears at a qualified specialist workshop.
! The tire inflation compressor should only
be connected to the 12 V socket in the
center console. You may otherwise
damage the vehicle's electrics.
! Do not operate the tire inflation
compressor for longer than 20 minutes at
a time without a break. The tire inflation
compressor may otherwise overheat.
The tire inflation compressor can be
operated again once it has cooled down. H
Environmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at aqualified specialist
workshop.
X Prepare the vehicle as described
(Y page 295).
X If possible, remove the foreign object that
has pierced the tire, e.g .the screw or the
nail.
It is beneficial to the sealing process if the
foreign body that has pierced the tire is
removed.
X Remove the Premium tire sealant, the
accompanying
"max 50 mph"("max80 km/h") sticker and
the tire inflation compressor from the
stowage compartmentint he right-hand
doorway (Y page 264).

You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that

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.

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
