2012 MERCEDES-BENZ SLK ROADSTER suspension

Vehicles travelling on
adifferent line DISTRONIC PLUS may not detect vehicles
travelling on a different line. The distance to
the vehicle in fron
twill be too short.
Other vehicles changing lane DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the carriage- way, because of its narrow width
.The dis-
tance to the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally. Dynamic handling package
General notes The adjustable suspension system adapts to
the particular driving conditions. Adjustment
depends on your individual selection, i.e.
sports or comfort. Your selection remains 164

stored even if you remove the key from the
ignition lock.
Sports tuning
The firmer setting of the suspension tuning in
sports mode ensures even better contact
with the road. Select this mode if you want to
experience direct contact with the road sur-
face, when employing a sporty driving style,
e.g. on winding country roads.

General notes The HOLD function can assist the driver in the
following situations:
R
when pulling away, especially on steep
slopes
R when manoeuvring on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is cancelled and the HOLD
function is deactivated when you depress the
accelerator pedal to pull away.
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary.
R the engine is running or if it has been auto-
matically switched off by the ECO start/
stop function.
R the driver's door is closed or if your seat
belt is fastened.
R the electric parking brake is released.
R the bonnet is closed.
R the selector lever is in position D,Ror Non
vehicles with automatic transmission.
R DISTRONIC PLUS is deactivated.
Activating the HOLD function X
Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal further
until ë appears in the multifunction dis-
play.
The HOLD function is activated. You can
release the brake pedal.
i If depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again. Driving systems

the
Tyre pressures will be dis‐ played after a few minutes of driv‐
ing message.
X Press the :button.
The Use current pressures as new reference values message appears in
the multifunctio ndisplay.
If you wish to confirm the restart:
X Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have drive
nfor a few minutes, the
system checks whether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Radio type approval for the tyre pres-
sure monitor In certain countries, a radio type approval for
the tyre pressure monitor may be required.

The "Breakdown assistance" section
(Y page 263) contains information and notes
on how to deal with a fla ttyre. It also provides
instructions on changing a wheel or fitting the
spare wheel/emergency spare wheel. Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the drivin gcharacteristics if
the wheels or tyres have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Always pay attention to the instructions and
safety notices in the section on "Wheel
changing and spare wheel fitting"
(Y page 266).
The wear patterns on the front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000km to 10,000 km depending on
the degree of tyre wear. Maintain the direc-
tion of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe-
cialist workshop. 294
Changing
awheelWheels and tyres

Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning .You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit a spare wheel/emergency spare
wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel/spare wheel. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protec tthe
tyres against oil, grease, petrol and diesel. Cleaning the wheels
G
WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent. Wheel and tyre combinations
Points to remember
! For safety reasons, Mercedes-Ben zrec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benzs pecifically 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-BenzO riginal
R MOE =Mercedes-BenzO riginal Extended
(tyres featuring run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (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 aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damage resulting from the use of tyres,
wheels or accessories othe rthan those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! 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.
i You will find a table of tyre pressures on
the inside of your vehicle's fuel filler flap.
For further information on tyre pressure,
see (Y page 289). Check tyre pressures
regularly, and only when the tyres are cold. Wheel and tyre combinations
