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 neutral positionN. 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.
Switch on the ignition (
page 40).

Move the selector lever to neutral
positionN.

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 375).
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.
