illustration on the following page.
There is a jack attachment located in the center on each side of the car. Position the jack on the bar in the attachment
as shown in illustration above and crank while simultaneously guiding the base of the jack to the ground. The base of
the jack must be flat on a level, firm, non-slippery surface. Before raising the car, check that the jack is still
correctly positioned in the attachment.
WARNING!
The jack's attachment must engage the bar in the jack attachment (see inset illustration above). The car's weight must
not rest on the jack attachment.
Raise the vehicle until both wheels on the side of the car where the jack is attached are lifted off the ground. Unscrew
the wheel bolts completely and carefully remove the wheel so as not to damage the thread on the studs.
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheels in the same location and
position as before removal. To lessen the chance of imbalance, each wheel hub is equipped with a guide stud to ensure
that a removed wheel can be reinstalled in its original position (as when changing over to winter tires/wheels).
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one that
came with the car. The use of different size wheels can seriously damage your car's transmission.

WARNING!
The jack's attachment must engage the bar in the jack attachment (A). The car's weight must not rest on the jack
attachment (B).
Be sure the jack is on a firm, level, non-slippery surface.
Never allow any part of your body to be extended under a car supported by a jack.
Use the jack intended for the car when replacing a wheel. For any other job, use stands to support the side of the
car being worked on.
Apply the parking brake, select position P (automatic transmission) or Reverse gear (manual transmission).
Block the wheels standing on the ground, use rigid wooden blocks or large stones.
The jack should be kept well-greased.
