Notice: If you use a jack to raise the vehicle
without positioning it correctly, you could
damage your vehicle. When raising your vehicle
on a jack, avoid contact with the rear axle
control arms.
Do not raise the vehicle yet. Put the compact
spare tire near you.
3. Locate the notch
(A is 3.0 inches
(7.5 cm) from the
front tire or B is
5.5 inches (14.0 cm)
from the rear tire).
The notch is located
near each wheel in
the vehicle's body.
CAUTION:
{
Getting under a vehicle when it is jacked
up is dangerous. If the vehicle slips off
the jack you could be badly injured or
killed. Never get under a vehicle when
it is supported only by a jack.
