188 WHAT TO DO IN EMERGENCIES
Procedure:
1. Park the vehicle on a firm, level, non-slippery
surface.
2. Switch on the hazard warning flasher switch, apply
the parking brake, and place the transmission
selector in "P".
WARNING!
The jack is designed exclusively for jacking up the
vehicle at the jack take-up brackets built into ei-
ther side of the vehicle. To help avoid personal in-
jury, use the jack only to lift the vehicle during a
wheel change. Never get beneath the vehicle
while it is supported by the jack only.
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 parking brake while the vehicle
is raised.
Always use the jack on a level surface.
Do not change wheels on either steep uphill or
downhill grades. Be sure that the jack arm end is
fully seated in the jack take-up bracket. The
vehicle may begin to move and fall from the jack
which could cause serious or fatal personal injury
and property damage.
Always lower the vehicle onto sufficient capacity
jack stands before working under the vehicle.
Precautions when changing a wheel:
For the torque, refer to "Installing a wheel";
Do not damage, grease or oil wheel bolts or their
threads.
Do not jack the vehicle up more than 1.2 in (30
mm) between the tire and the surface. Otherwise,
the vehicle may tip over and may cause serious
injury or death to you or others.
