Up Stick ,tor epair slight damage to the paint-
work quickly and provisionally.
Matt ef inish care
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following may cause the paint to
become shiny and thus reduce the matte
effect: R
strong rubbing of the paintwork with
unsuitabl em aterialsR
frequent use of automatic car washes R
washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitabl ef or high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically ,tos hiny, spotted areas.
Alway sh ave paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with ah ot wax
treatment under any circumstances.
Observe these notes if your vehicle has ac lear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
ac lear matte finish.
The vehicle should ideally be washed by hand
using as oft sponge, car shampoo and plenty of
water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products.
Cleaning the vehicl ep arts
Cleaning the wheels

blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amage dint his way may fail unexpect-
edly .T here is ar isk of an accident. Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis component sr eplaced imme-
diately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for al ong period of
time directly after cleaning, particularl ya fter

system (Canad ao nly) or tire pressure monitor
(USA only).
If ap ressure loss warning message appears
in the multifunction display: R
observe the instructions in the displa ym es-
sages ( Y
page 211).R
check the tire for damage R
if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partiall yl aden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed am aximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires: R
size R
type and R
the "MOExtended" marking
If at ire has gone flat and cannot be replaced
with aM OExtended tire, as tandard tire may be
used as at emporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with aT IREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. AT IREFIT kit may be obtained from
aq ualified specialist workshop.
Important safety notes
G WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner- ing, accelerating quickly and when braking.
There is ar isk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to al aden
vehicle.
Stop driving in emergency mode if: R
you hear banging noises. R
the vehicle starts to shake. R
you see smoke and smell rubber. R
ESP ®
is intervenin gc onstantly.R
there are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at aq ualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes TIREFIT is at ire sealant.
Only valid for USA: You can use TIREFIT to seal
punctures of up to 0.16 in (4 mm), particularly
those in the tire tread. You can use TIREFIT at
outside temperatures down to

If at ire pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes: X
Switch off the tire inflation compressor. X
Unscrew the fille rh ose from the valve of the
faulty tire.
Note that tire sealant may escape when you
unscrew the fille rh ose.X
USA only: Stow the tire sealant bottle and the
tire inflation compressor. X
Pull away immediately .X
Stop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
G WARNING
If the required tire pressure is not reached
after driving for as hort period ,t he tire is too
badl yd amaged. 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 char-
acteristics. There is ar isk of accident.
Do not continue driving. Contact aq ualified
specialist workshop.
i USA only: In cases such as the one men-
tioned above ,c ontact an authorized
Mercedes-Benz Center. Or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada). X
USA only: Correct the tire pressure if it is still
at least 130 kPa (1.3 bar/19 psi). See the Tire
and Loading Information placard on the driv-
er's side B-pilla rort he tire pressure table in
the fuel fille rf lap for values.X
To increase the tire pressure: switch on the
tire inflation compressor. X
To reduce the tire pressure: depres sp res-
sure release button C next to pressure
gauge D . X
When the tire pressure is correct, unscrew the
fille rh ose from the valve of the sealed tire.
Note that tire sealant may escape when you
unscrew the fille rh ose.X
Screw the valve cap onto the tire valve of the
sealed tire.
X
To remove the tire sealant bottle from the tire
inflation compressor, press together the lock-
ing tabs on the yellow cap. X
Pul lt he tire sealant bottle out of the tire infla-
tion compressor.
The fille rh ose remains attached to the tire
sealant bottle. X
Drive to the nearest qualifie ds pecialist work-
shop and have the tire changed there. X
Have the tire sealant bottle and the fille rh ose
replaced as soon as possible at aq ualified
specialist workshop. X
Have the tire sealant bottle replaced every
