Safety notes
Your vehicle may be equipped with a TIREFIT
kit or a spare wheel with collapsible tire.
Vehicles
with a TIREFIT kit do not have a spare
wheel.
For information on your vehicle’s equipment,
see “Rims and tires” ( Y page 297).G
Warning!
The dimensions of the spare wheel are
different from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Contact the nearest authorized Mercedes-
Benz Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never
operate the vehicle with more than one
spare wheel mounted.
Do not switch off the ESP ®
when a spare
wheel is mounted. Preparing the vehicle
X Whenever possible, park the vehicle in a
safe
distance from moving traffic on a hard,
flat surface.
X Turn on the hazard warning flasher.
X Turn the steering wheel so that the front
wheels are in a straight-ahead position.
X Engage the parking brake.
X Shift the automatic transmission into park
position P (manual transmission to 1st or
reverse gear R).
X Turn off the engine.
X Remove the SmartKey from the starter
switch.
X Have any passenger exit the vehicle at a
safe distance from the roadway. Open
doors only when conditions are safe to do
so. Sealing tires with TIREFIT
This section applies to SLK 55 AMG with
Performance Package only.
Small
tire punctures, particularly those in the
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient temperatures
down to -4‡ (-20†). G
Warning!
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage
caused by driving with extremely low
tire inflation pressure, or on a flat tire, or a
damaged wheel.
Do not drive the vehicle under such
circumstances.

Benz Center for assistance or call Roadside
Assistance. Flat tire

Switch off the tow-away alarm before
towing the vehicle with all wheels on the
ground or one axle raised ( Y page 52).
! Before towing the vehicle observe the
following instructions:
R Vehicles with automatic transmission:
Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts. G
Warning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R Vehicles with automatic transmission:
the automatic transmission will remain in
park position P For more information see “Battery”
(Y page 282) or “Jump starting”
(Y page 283).
Vehicles with automatic transmission: For
information on manually unlocking the gear
selector lever, see (
Y page 266). Installing towing eye bolt
Depending on whether you are towing a
vehicle or you are being towed, the towing eye
bolt can be screwed into threaded holes
which are located behind covers on each
bumper.
The towing eye bolt is supplied with the
vehicle tool kit, located in the compartment
underneath the trunk floor (Y page 234).
X Take the vehicle tool kit out of the trunk.
Removing cover in front bumper X
Press mark on cover : as indicated by the

Warning!
If circumstances require towing the vehicle
with all wheels on the ground, always tow with
a tow bar if:
R the engine will not run
R there is a malfunction in the brake system
R there is a malfunction in the power supply
or in the vehicle’s electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position 2.
If the SmartKey is left in the starter switch
position 0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert. G
Warning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
X Make sure the ignition is switched on.
X With the vehicle at a standstill, depress the
brake pedal and keep it pressed.
X Vehicles with manual transmission: Shift
the manual transmission into the neutral
position (no gear selected).
or
X Vehicles with automatic transmission: Shift
the automatic transmission into neutral
position N.
X Release the brake pedal.
X If engaged, release the parking brake.
X Switch on the hazard warning flasher
(Y page 74). !
The vehicle may be towed only for
distances up to 30 miles (50 km) and at a
speed not to exceed 30 mph (50 km/h).
i While being towed with the hazard
warning
flasher in use, use the combination
switch in the usual manner to signal turns.
Only the selected turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again. Fuses
Introduction
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating. G
Warning!
Only use fuses approved by Mercedes-Benz
with
the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.
A blown fuse must be replaced by an
appropriate spare fuse (recognizable by its
color or the fuse rating given on the fuse) of
the amperage recommended in the fuse
chart. Any Mercedes-Benz Center will be glad
to advise you on this subject.
i In case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-
Benz Center.
If a newly inserted fuse blows again, have the
cause determined and rectified by an
authorized Mercedes-Benz Center.
The fuse chart is located in the fuse box in the
passenger compartment. The fuse chart 288
