Emergency Towing
If you decide to tow your vehicle
with all four wheels on the groud,
make sure you use a properly-
designed and attached tow bar.
Prepare the vehicle for towing as
described above, and leave the
ignition switch in Accessory (I) so
the steering wheel does not lock.
Make sure the radio and any items
plugged into the accessory power
socket are turned off so they do not
run down the battery.
NOTICE
The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in Accessory (I), and
make sure the steering wheel turns
freely before you begin towing.
Taking Care of the Unexpected
NOTICE
Trying to lift or tow your vehicle by the
bumpers will cause serious damage.
The bumpers are not designed to
support the vehicle's weight.
