2015 MERCEDES-BENZ SLK-CLASS ROADSTER flat tire

If a tire pressure of 200 kPa (2.0 bar/29 psi)is achieved after a maximum of ten minutes,
see ( Ypage 298).
If a tire pressure of 200 kPa (2.0 bar/29 psi) is not achieved after a maximum of ten
minutes, see ( Ypage 298).
iIf tire sealant leaks out, allow it to dry. It
can then be removed like a layer of film.
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 achieved after ten minutes: X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tire.
X Very slowly drive forwards or reverse
approximately 30 ft (10 m).
X Pump up the tire again.
After a maximum of ten minutes, the tire
pressure must be at least 200 kPa (2.0 bar/
29 psi).
GWARNING
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 tirepressure 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
GWARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk ofaccident.
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.
!Residue from the tire sealant may come
out of the filler hose after use. This could
cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialistworkshop.
If tire pressure of 200 kPa (2.0 bar/29 psi)
has been achieved after a maximum period of ten minutes:
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tire.
X Stow the tire sealant bottle and the tire
inflation compressor.
X Pull away immediately .
The maximum 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.
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).
GWARNING
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.

GWARNING
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tires without run-flat characteristics:
R do not drive with a flat tire.
R immediately replace the flat tire with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tires with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tires (tires with
run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair operating safety.

Operation
Information on driving
Check the tire pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics. If you find no signs of damage, have the tires
and wheels checked at a qualified specialist
workshop.
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
312Operation
Wheels and tires

curbs, speed humps or similar elevations, tryto do so slowly and at an obtuse angle. Oth-
erwise, the tires, particularly the sidewalls,
may be damaged.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Regularly check the wheels and tires of your
vehicle for damage at least once a month, as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of
tire pressure. Pay particular attention to dam-
age such as:
R cuts in the tires
R punctures
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 ( Ypage 313). 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
particularly prior to long trips. Adjust the tire pressure as necessary ( Ypage 315).
Observe the notes on the emergency spare
wheel ( Ypage 343). 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
GWARNING
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: âin (3 mm)
R M+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator for
tread wear (arrow) is integrated into the tire
tread.
Treadwear indicators (TWI) are required by
law. Six indicators are positioned on the tire
tread. They are visible once a tread depth of
Operation313
Wheels and tires
Z

approximatelyáin(1.6 mm) has been
re ached. If this is the case, the tire is so worn
that it must be replaced.
Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section(Y page 295).
R Only mount tires of the correct size onto
the wheels.
R Break in new tires at moderate speeds for
the first 60 miles (100 km). They only reach
their full performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear.
MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires.
MOExtended tires may only be used in con-
junction 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 ( Ypage 295).
iVehicles 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 quali-
fied specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
Observe the notes in the "Changing a wheel"
section ( Ypage 334).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use win-
ter tires or all-season tires. Both types of tire are identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking pro-

vide the best possible grip in wintry road con-ditions.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tires have been devel-
oped specifically for driving in snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac- teristics.
Always observe the maximum permissible
speed specified for the M+S tires you havemounted.
When you have mounted the M+S tires:
X Check the tire pressures ( Ypage 319).
X Vehicles for Canada: restart the tire pres-
sure loss warning system ( Ypage 319).
X Restart the tire pressure monitor (Y page 320).
Information about driving with an emergency spare wheel ( Ypage 343).
Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
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 correspondingstandard of quality. For more information,
please contact a qualified specialist work-shop. 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. Permissible
wheel-tire combinations ( Ypage 339).
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi-
ble when you come to a road that is not
snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to install snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
You may wish to deactivate ESP ®
when pull-
ing away with snow chains installed( Y page 64). You can thereby allow the wheels
to spin in a controlled manner, achieving an
increased driving force (cutting action).

Underinflated or overinflated tires
Underinflation
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition, they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-ing properties and the driving characteristics.There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
R overheat, leading to tire defects
R have an adverse effect on handling charac-
teristics
R wear quickly and unevenly
R have an adverse effect on fuel consumption
Overinflation
GWARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the
driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel. Overinflated tires may:
R increase the braking distance
R have an adverse effect on handling charac-
teristics
R wear quickly and unevenly
R have an adverse effect on ride comfort
R be more susceptible to damage
Maximum tire pressures
:Example: maximum permissible tire pres-
sure
Never exceed the maximum permissible tire
