3. Find the jacking location using
the diagram above, and the
corresponding V-shaped locating
notches in the plastic molding.
Getting under a vehicle when it is
lifted on a jack 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.
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
4. If you have a coin/pierce jack,
attach the jack handle extension
to the jack by sliding the hook
through the end of the jack and
insert the other end of the jack
handle into the wrench.
If you have a hex head jack,
place the hex tube end of the
wrench over the hex head of
the jack.
