2017 MERCEDES-BENZ GLC tires

If water no longer forms "beads" on the paint
surface, use the paint care products recommen-
ded and approved by Mercedes-Benz. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
The cleaning product Paint Cleaner, which has
been recommended and approved by
Mercedes-Benz, should be used when dirt has
penetrated the paint surface.
Also use Paint Cleaner on paint that has become
dull.
Do not use these care products in the sun or on
the hood while the hood is hot. X
Use a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint-
work quickly and provisionally.
Matte finish 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
unsuitable materials R
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 suitable for high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear
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
a clear matte finish.
The vehicle should preferably be washed by
hand using a soft 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 vehicle parts
Cleaning the wheels
G WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced 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 a long period of
time directly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.
Cleaning the windows
G WARNING
You could become trapped by the windshield
wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise a risk of damaging the windows.314

If your clothes are soiled with tire sealant, have
them cleaned with perchloroethylene at a dry
cleaner as soon as possible.
Tire pressure not reached If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of the
faulty tire.
Tire sealant may escape when the filler hose is
unscrewed. X
Very slowly drive forwards or reverse approx-
imately 30 ft (10 m). X
Pump up the tire again.
After a maximum of ten minutes, the tire pres-
sure must be at least 200 kPa (2.0 bar/
29 psi).
G WARNING
If the required tire pressure is not reached
after the specified time, 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 char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
G WARNING
A tire 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 permissible speed for a tire
sealed with tire sealant is 50 mph (80 km/h).
The upper part of the TIREFIT sticker must be
affixed to the instrument cluster in the driver's
field of vision. If a tire 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 filler hose from the valve of the
faulty tire.
Tire sealant may escape when the filler hose is
unscrewed. X
Stow the tire sealant bottle and the tire infla-
tion 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 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 char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
In cases such as the one mentioned above, con-
tact an authorized Mercedes-Benz Center. Or
call 1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada). X
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 B-pillar on
the driver's side or the tire pressure table in
the fuel filler flap for values. X

heavily laden and adjust prio r to a trip.
While driving , pay attention to vibrations, noises
and unusual handlin g characteristics , e.g. pull-
ing to on e side . This may indicat e that th e
wheels or tires are damaged. If you suspec t that
a tire is defective, reduce your spee d immedi-
ately. Stop th e vehicl e as soo n as possible to
chec k th e wheels and tires for damage. Hidden
tire damag e could also be causing th e unusual

off-road or on rough roads. Damaged wheels
can cause a loss of tire pressure.
Pay particular attention to damage such as: R
cuts in the tires R
punctures in the tires R
tears in the tires R
bulges on tires R
deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire ( Y
page 337). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not mount
anything onto the valve other than the standard
valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not use any
other valve caps or systems, e.g. tire pressure
monitoring systems.
Regularly check the pressure of all the tires par-
ticularly prior to long trips. Adjust the tire pres-
sure as necessary ( Y
page 339).
The service life of tires depends, among other
things, on the following factors: R
Driving style R
Tire pressure R
Distance covered
Notes on tire tread
G WARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for: R
Summer tires:

MOExtended tires (tires with run-flat
properties) With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tires.
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor
and on wheels specifically tested by Mercedes-
Benz.
Notes on driving with MOExtended tires with a
flat tire ( Y
page 321).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit can be obtained from
a qualified specialist workshop.
Winter operation
General notes Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section ( Y
page 356).
Driving with summer tires At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tires. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
G WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately. M+S tires

For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specially approved for your vehicle by
Mercedes-Benz, or are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
If you intend to mount snow chains, please bear
the following points in mind: R
Snow chains may not be mounted on all
wheel/tire combinations. Observe the infor-
mation regarding permitted wheel/tire com-
binations ( Y
page 360).R
Only use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered. R
Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Do not exceed the maximum permissible
speed of 31 mph (50 km/h). R
On vehicles with AIR BODY CONTROL, you
must only drive at raised vehicle level if snow
chains have been installed ( Y
page 173).R
When snow chains are installed, never use
Active Parking Assist ( Y
page 178).
You may wish to deactivate ESP ®
when pulling
away with snow chains installed: R

Important safety notes
G WARNING
Underinflated or overinflated tires pose the
following risks: R
the tires may burst, especially as the load
and vehicle speed increase. R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction. R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel: R
