2014 MERCEDES-BENZ SLK ROADSTER Owners Manual

release the parking brake while the vehicle
is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat, load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. a rubber mat.
R do not use wooden blocks or similar
objects as a jack underlay. Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure that the distance between the
underside of the tyres and the ground does not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. X
Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one full turn. Do not unscrew the bolts com-
pletely. The jacking points are located just behind the
front wheel arches and just in front of the rear wheel arches (arrows). Covers, front (example: vehicles with AMG equip-
ment)
AMG vehicles and vehicles with AMG
equipment: to protect the vehicle body, the
vehicle has covers fitted next to the jacking
points on the outer sills.
X AMG vehicles and vehicles with AMG
equipment: fold cover;upwards. X
Position jack ?at jacking point =.326
Changing a wheelWheels and tyres

Example
X Make sure that the base of the jack is posi-
tioned vertically under the jacking point.
X Turn crank Aclockwise until jack ?sits
completely on jacking point =and the
base of the jack lies evenly on the ground.
X Turn crank Auntil the tyre is raised a max-
imum of 3 cm off the ground.
Removing a wheel !
Do not place wheel bolts in sand or dirt.
The threads of the wheel bolts and wheel
hubs could otherwise be damaged when
the bolts are tightened. X
Unscrew the uppermost wheel bolt com-
pletely.
X Screw centring pin :into the thread
instead of the wheel bolt.
X Unscrew the remaining wheel bolts fully.
X Remove the wheel. Fitting a new wheel G
WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Observe the instructions and safety notes on "Changing a wheel" (Y page 323).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel. X
Clean the wheel and wheel hub contact
surfaces.
X Slide the wheel to be mounted onto the
centring pin and push it on.
X Tighten the wheel bolts until they are fin-
ger-tight. Changing a wheel

X
Unscrew the centring pin.
X Tighten the last wheel bolt until it is finger-
tight.
X Vehicles with a collapsible emergency
spare wheel: inflate the collapsible emer-
gency spare wheel (Y page 335). Only then
lower the vehicle.
Lowering the vehicle G
WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed. X
Turn the crank of the jack anti-clockwise
until the vehicle is once again standing
firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated ( :
to A). The specified tightening torque is
130 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the vehicle
tools in the boot again.
X AMG vehicles and vehicles with AMG
equipment: insert the cover into the outer
sill.
X Check the air pressure of the newly fitted
wheel and adjust accordingly. Observe the recommended tyre pressure
(Y
page 318).
i If you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Do not restart the tyre pressure loss warn- ing system/tyre pressure monitor until the
defective wheel has been replaced with a
new wheel.
Vehicles with a tyre pressure control
system: all fitted wheels must be equipped
with functioning sensors. Wheel and tyre combinations
General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle. 328
Wheel and tyre combinationsWheels and tyres

Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes- ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit
used tyres if you have no information about their previous usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
Overview of abbreviations used in the follow-
ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
You will find a table with recommended tyre
pressures for various operating conditions on
the inside of your vehicle's fuel filler flap. For
further information on tyre pressure, see
(Y page 318). Check tyre pressures regularly
and only when the tyres are cold.
Notes on the vehicle equipment – always fit
the vehicle:
R with tyres of the same size on a given axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with run-flat characteristics" section
(Y
page 296).
Vehicles with MOExtended tyres 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 fit tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.

fitted at the factory in all countries. Wheel and tyre combinations
