keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle. Adapt your driving accord-
ingly.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking
activated and the key 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.

(page 80).
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (

done using the properly installed
towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle
