Transporting the vehicle
The towing eyes can be used to pull the ve-
hicle onto a trailer or transporter for trans-
porting purposes.
Turn the key to position 2 in the ignition
lock.
Move the transmission selector lever
to N.
!
Only lash the vehicle down by the wheels or
rims, not by vehicle parts such as axle or steering
components. There is otherwise a risk of damage
to the vehicle.
