330 Practical hintsTowing the vehicleWarning!
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.
!When towing the vehicle with all wheels
on the ground, please note the
following:
With the automatic central locking
activated 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.
Switch off the tow-away alarm
(page 79).
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 133).
Towing of the vehicle should only be
done using the properly installed
towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle
chassis, frame or suspension parts.
iIf the battery is disconnected or
discharged
the SmartKey will not turn in the
starter switch. See notes on the
battery (
page 323) or on jump
starting (page 326).
the gear selector lever will remain
locked in positionP. See notes on
manually unlocking transmission
gear selector lever (
page 308).
