Jacking up
Take the wheel wrench out of the
vehicle tool kit tray.
On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench).
The jack take-up brackets are located
directly behind the front wheel housings
and in front of the rear wheel housings as
indicated by the arrows.
Warning!
The jack is designed exclusively for
jacking up the vehicle at the jack take-up
brackets. Make sure the jack arm is fully
seated in the jack take-up bracket.
If you do not position the jack correctly in
the jack take-up bracket, the vehicle can:
fall off the jack
seriously or fatally injure you or others
!
Do not position the jack on the body of the
vehicle, as this may cause damage to the
vehicle.
