2006 MERCEDES-BENZ SLK350 Smart key

426 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Vehicles with automatic transmission*:
Do not tow-start vehicle.!Use flatbed or wheel lift/dolly equip-
ment with the SmartKey in the starter
switch in position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 88) and the automatic central
locking (
page 101).
!To be certain to avoid a possibility of
damage to the transmission, however,
we recommend the drive shaft be dis-
connected at the rear axle drive flange
for any towing beyond a short tow to a
nearby garage.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch
position0or1). Otherwise, the ESP
®
will immediately be engaged and will
apply the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever*
must be in positionN (manual trans-
mission: gear shift lever in neutral posi-
tion) and the SmartKey must be in
starter switch position1.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

427 Practical hints
Towing the vehicle
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Warning!
G
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 ve-
hicle. Adapt your driving accordingly.iTo signal turns while being towed with
the hazard warning flasher in use,
switch on ignition and activate the
combination switch for the left or right
turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 101).
Switch off the tow-away alarm
(
page 88).
The vehicle should only be towed using
a properly installed towing eye bolt.
Never attach a tow cable, tow rope or
tow rod to the vehicle chassis, frame or
suspension parts.

428 Practical hintsTowing the vehicleInstalling towing eye bolt
The towing eye bolt is supplied with the ve-
hicle tool kit, located in the compartment
underneath the trunk floor (
page 388).
The towing eyes are located on the passen-
ger side in the front and rear bumper.

Take vehicle tool kit out of trunk
(page 388).Front cover

Press mark on cover1.

Cover1 springs open at the top right
corner.

Pull at the protruding part of cover1
and fold cover down to reveal the
threaded hole for the towing eye bolt.
Do not disconnect cover1 from its
check strap.

Screw towing eye bolt in to its end stop
and tighten with lug wrench.Installing

Unscrew the towing eye bolt using the
lug wrench.

To reinstall cover1, tilt the marked
lower left corner towards the opening.

Maintaining its tilted position, insert
cover1 by applying the latches at the
top left and lower right corner into the
opening.

To close cover1, press on the diago-
nal opposite side of the marked corner
until it fully engages.
iThe gear selector lever* will remain
locked in positionP (vehicles with au-
tomatic transmission*) and the
SmartKey will not turn in the starter
switch if the battery is disconnected or
discharged. See notes on the battery
(page 421) or on jump starting
(page 424).
Vehicles with automatic transmission*:
For information on manual unlocking of
gear selector lever, see (
page 396).
iMake sure the cover’s check strap
does not get caught when closing.

The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line’s ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
Shift lock*
When the vehicle with automatic trans-
mission is parked, this lock prevents
the gear selector lever from being inad-
vertently moved out of positionP with-
out the SmartKey turned and the brake

vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.Tightening torque
Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.
