clutch MERCEDES-BENZ SLK350 2010 R171 Owner's Manual

!
Vehicles with rain sensor: Do not leave
windshield wipers on an intermittent
setting when the vehicle is taken to an
automatic car wash or during windshield
cleaning. Windshield wipers will operate in
the presence of water sprayed on the
windshield, and windshield wipers may be
damaged as a result.
! Vehicles with rain sensor: If you have set
intermittent wiping, dirt on the surface of
the
rain sensor or optical effects may cause
the windshield wipers to wipe in an
undesired fashion. This could then damage
the windshield wiper blades or scratch the
windshield. You should therefore switch off
the windshield wipers when weather
conditions are dry.
Vehicles with rain sensor: Intermittent wiping
interval is dependent on the wetness of the
windshield. After the initial wipe, pauses
between wipes are controlled by the rain
sensor automatically.
X Turn the combination switch to position I.
Intermittent wiping is interrupted when the
vehicle
is at a standstill and a door is opened.
This protects persons getting into or out of
the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and
R the clutch pedal is depressed (vehicles with
manual transmission)
or
R the automatic transmission is in drive
position D or reverse gear R (vehicles with
automatic transmission)
the automatic transmission is in drive
position D or reverse gear R
or
R the wiper setting is changed using the
combination switch Single wipe X
Press the combination switch briefly in
direction of arrow A to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with washer fluid X
Press the combination switch in direction
of arrow A past the resistance point.
The

windshield wipers operate with washer
fluid.
i To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with
washer

fluid every now and then even when
it is raining.
For information on filling up the washer
reservoir, see “Washer system and headlamp
cleaning system” ( Y page 196).
For information on cleaning the headlamps
with washer fluid, see “Headlamp cleaning
system” ( Y page 74). Problems with wipers
! If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.
For

safety reasons, do the following before
attempting to remove any blockage:
R Stop the vehicle in a safe location.
R Remove the SmartKey from the starter
switch.
R Engage the parking brake.
R Remove blockage.
R Turn the windshield wipers on again. Wipers

Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.

Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result
in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
! Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service life of the engine. This is not covered by the
Mercedes-Benz Limited Warranty.
! If an acoustic warning sounds and the
message Release Parking Brake
appears in the multifunction display when
driving off, you have forgotten to release
the parking brake.
Release the parking brake.
! Avoid

spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
! Simultaneously depressing the
accelerator pedal and applying the brakes
reduces engine performance and causes
premature brake and drivetrain wear which
is not covered by the Mercedes-Benz
Limited Warranty.
i Once the vehicle is in motion, the
automatic central locking function engages
and the locking knobs in the doors move
down.
The automatic central locking function can
be switched off ( Y page 108).

Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result
in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
! When you are shifting the manual
transmission into the 5th or 6th gear,
make sure you move the gearshift lever to
the right. Otherwise, you could accidentally
shift into the 3rd or 4th gear and damage
the manual transmission.
Downshifting gears leading to overrevving
the engine can result in engine damage that
is not covered by the Mercedes-Benz
Limited Warranty.
Never hold the vehicle stopped on a hill by
using the clutch pedal. The clutch may be
damaged which is not covered by the
Mercedes-Benz Limited Warranty.
! Avoid driving at excessive engine speeds.
This may result in serious engine damage
that is not covered by the Mercedes-Benz

Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 79). G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets

in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
! Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature has
been reached.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces.
This may cause serious damage to the
engine and the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
i During the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more quickly
to operating temperature. Automatic transmission

control. Your vehicle’s ABS will not prevent
this type of loss of control.
The most important rule for slippery or icy
roads
is to drive sensibly and to avoid abrupt
acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, shift
the automatic transmission to neutral
position N or declutch in case of manual
transmission. Try to keep the vehicle under
control by corrective steering action.
i For information on driving with snow
chains, see “Snow chains” ( Y page 220).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal brake effect.
Depressing the brake pedal periodically when
traveling at length on salt-strewn roads can
bring road-salt-impaired braking efficiency
back to normal.
If the vehicle is parked after being driven on
salt-treated roads, the braking efficiency
should be tested as soon as possible after
driving is resumed. G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. Driving instructions
Drive sensibly – save fuel
To save fuel you should:
R Keep tires at the recommended inflation
pressures.
R Remove unnecessary loads.
R Allow engine to warm up under low load
use. R
Avoid frequent acceleration and
deceleration.
R Have all maintenance work performed at
the intervals specified in the Maintenance
Booklet and as required by the
Maintenance system. Contact an
authorized Mercedes-Benz Center.
Fuel
consumption is also increased by driving
in cold weather, in stop-and-go traffic, on
short trips and in mountainous areas. Drinking and driving
G
Warning!
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident

are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs. Pedals
G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
