8. Reinstall all the wheel nuts fin-ger tight.
Reinstall the wheel nuts (tapered end
inward) and tighten them as much as
you can by hand. Press back on the
tire and see if you can tighten them
more.
CAUTION
Never use oil or grease on the
bolts or nuts. Doing so may lead
to overtightening the nuts and
damaging the bolts. The nuts
may loose and the wheels may
fall off, which could cause a seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.
9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclock-
wise to lower the vehicle.
Use only the wheel nut wrench 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.

11. Check the air pressure of the re-placed tire.
Adjust the air pressu re to the specifi-
cation designed on page 334 in Sec-
tion 8. If the pre ssure is lower, drive
slowly to the nearest service station
and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
12.Restow all the tools, jack and flat tire securely.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 334 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion 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.
Vehicles with traction control system—
Turn off the traction control system to
become unstuck to allow the tires to
spin enough to remove the vehicle from
the obstruction. (For details, see “Trac-
tion control system” on page 133 in
Section 17.)
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.

Front (on some models)
Rear (on some models)
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
Manual transmission vehicles with front
and/or rear towing eyelet, or automatic
transmission vehicles with front towing
eyelet—If towing service is not avail-
able in an emergency, your vehicle may
be temporarily towed by a cable or
chain secured to one of the emergency
towing eyelets under the vehicle. Use
extreme caution when towing vehicles.
Vehicles with an automatic transmis-
sion, use only the front towing eyelet
when towing your vehicle.
Front towing eyelet—To install the front
towing eyelet, see “—Installing front tow-
ing eyelet” on page 277 in this Section.NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
 Vehicles with an automatic trans-
mission, never tow a vehicle from
the rear with four wheels on the
ground. This may cause serious
damage to the transmission.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard− surfaced 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.

2005 CAMRY from Sep. ’04 Prod. (OM33684U)
CAUTION
Use extreme caution when towing ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing eyelets and towing cable or
chain. The eyelets 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 eyelets provided.
Before towing, release the parking brake
and put the transmission in “N” (automat-
ic) or neutral (manual). 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.

4. Tighten the front towing eyelet securelyby a wheel nut wrench.
CAUTION
When installing the eyelet on the ve-
hicle, be sure to tighten the front
eyelet securely. If the eyelet is loose,
it may come off when being towed
and result in death or serious injury.
If you cannot shift the selector lever
out of “P” position to other positions
even though the brake pedal is de-
pressed, use the shift lock override but-
ton as follows:
1. Turn the ignition key to “LOCK” position. Make sure the parking
brake is on.
2. Pry up the cover with a flatbladed screwdriver or equivalent.3. Insert your finger into the hole topush down the shift lock override
button. You can shift out of “P”
position only while pushing the but-
ton.
