8. Lower the vehicle completely andtighten the wheel nuts.
Turn the jack handle counterclockwise to
lower the vehicle.
Use only the wheel nut wrench and turn
it clockwise to tighten the nuts. Do not
use other tools or any additional leverage
other than your hands, such as a hammer,
pipe or your foot. Make sure the wrench
is securely engaged over the nut.
Tighten each nut a little at a time in the
order shown. Repeat the process until all
the nuts are tight.
CAUTION
When lowering the vehicle, make
sure all portions of your body and
all other persons around will not be
injured as the vehicle is lowered to
the ground.
Have the wheel nuts tightened by
torque wrench at 103 N·m (10.5
kgf·m, 76 ft·lbf), as soon as pos-
sible after changing wheels. Other-
wise, the nuts may loosen and the
wheels may fall off, which could
cause a serious accident.
9. Install the flat tire and spare tire cover on the back door.
CAUTION
Make sure flat tire and spare tire cov-
er are securely in place in their stor-
age location to reduce the possibility
of personal injury during a collision
or sudden braking.

3. Lock the latch handle which is on thebottom of the cover.
Check that the cover is securely in place. 10. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specification
designated on page 258 in Section 8. If
the pressure is lower, drive slowly to the
nearest service station and fill to the cor-
rect pressure.
Do not forget to reinstall the tire inflation
valve cap as dirt and moisture could get
into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
11. Restow all the tools and jack secure- ly.
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified on page 258 in Section 8 with
a torque wrench. Have a technician repair
the flat tire.
CAUTION
Before driving, make sure all the
tools and jack are securely in place
in their storage location to reduce the
possibility of personal injury during a
collision or sudden braking.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.

NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hardsurfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing eyelet and towing cable or
chain. The eyelet and towing cable or
chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.
Before towing, release the parking brake
and put the transmission in neutral (manu-
al) or “N” (automatic). The key must be
in “ACC” (engine off) or “ON” (engine run-
ning).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
Before emergency towing, check that
the eyelet is not broken or damaged
and that the installation bolts are not
loose.
Fasten the towing cable or chain se-
curely to the eyelet.
Do not jerk the eyelet. Apply steady
and even force.
