361 Practical hints
Towing the vehicle
Prior to towing the vehicle with all wheels on
the ground, make certain that 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.iTo signal turns while being towed with
the hazard warning flasher in use, turn
SmartKey in starter switch to
position2 and activate the combina-
tion switch for the left or right turn sig-
nal in the usual manner – only the
selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
Warning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. For more information, see
“Electrohydraulic brake system”
(page 84).
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.
!Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.iWhen 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 approximately 9 mph
(15 km/h) or more.
To prevent the vehicle door locks from
locking, deactivate the automatic
central locking (
page 137).
362 Practical hintsTowing the vehicleInstalling/reinstalling towing eye bolt
Take the towing eye bolt1 from its
storage compartment (
page 342).1Towing eye bolt
Remove cover from the access hole.
Screw towing eye bolt1 in to its stop.
Remove the towing eye bolt when you
no longer need it. To do this, carry out
the above steps in reverse order.
Points to bear in mind
The vehicle must not be tow-started.
If the vehicle is to be towed, only tow it
with all wheels on the ground.
If the vehicle has suffered transmission
damage, only tow it with the propeller
shaft disconnected.
Before towing the vehicle, make sure
the battery is connected and charged.
Otherwise you will not be able to switch
on the ignition and move the selector
lever to N. There will then be no power
assistance when steering and braking.
Transporting the vehicle
The towing eye bolt can be used to pull the
vehicle onto a trailer or transporter for
transporting purposes.
Move the selector lever to N.
iThe gear selector lever will remain
locked in positionP and the SmartKey
will not turn in the starter switch if the
battery is disconnected or discharged.
See notes on the battery (
page 356).
!Only secure the tow bar to the towing
eye bolt. The vehicle could otherwise
be damaged.!Your vehicle is equipped with a front
towing eye bolt only (
page 362).
You cannot tow other vehicles with
your vehicle.
!Due to the low clearance height of the
SLR, care must be taken when loading
and unloading from a transporter to
avoid damaging the vehicle body work.
To secure the vehicle, only tie it down
by the wheels or tires. Otherwise it
could be damaged.
