Vehicles with factory-mounted
running-boards*:
Your vehicle is equipped with a scissors-type
jack (located under the cargo compartment
floor) designed for use with factory-mounted
running boards. Only use this jack when jacking
up vehicles with factory-mounted running boards
as otherwise the vehicle’s underbody can be
damaged. See separate instructions for scis-
sors-type jack.
!
To prevent damage, always disengage the
strap of the securing hook and lower the cargo
compartment floor (
page 469) before closing
the tailgate.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage the parking brake while
the vehicle is raised. Be certain that the jack
is always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on a level surface.
Make sure that the jack arm is fully seated
in the jack take-up bracket. Always lower
the vehicle onto jackstands of sufficient
capacity before working under the vehicle.
