Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm flat, sur-
face. Switch on the hazard warning
flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse, selector lever in Park with
automatic transmission, and engage
the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for instance.
If a warning triangle or portable hazard
warning lamp is required, set it up on
the roadside at an appropriate distance
from the rear of the vehicle.
Comply with all safety guidelines and
regulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle up on a soft or slip-
pery surface, snow, ice, very smooth
surfaces, etc., since it could slide side-
ways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. Failure to comply with this
creates a risk of fatal injury.<

2. Secure the vehicle to prevent it from
rolling:
Place the wedges (chocks) behind
the wheels on the side opposite the
side you are lifting. If the vehicle is
parked on a downward slope, place
the wedges securely in front of the
wheels. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from
rolling
3. Loosen the lug bolts 1/2-turn
4. Insert the jack handle into the jack,
refer to the illustration in the next
column5. Position the jack at the jacking point
closest to the flat tire so that the jack
base is vertically below the jacking
point and the entire surface of the
head of the jack will move into the
square recess of the jacking point,
refer to the illustration detail, when
the jack is cranked
