Before putting on wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation
of wheels without good metal−to−met-
al contact at the mounting surface can
cause wheel nuts to loosen and
eventually cause a wheel to come off
while driving.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 completelyand 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.
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
with torque wrench to 103 N·m
(10.5 kgf·m, 76 ft·lbf), as soon
as possible after changing
wheels. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.
 Do not attach a heavily dam-
aged plastic wheel ornament.
It may fly off the wheel and
cause accidents while the ve-
hicle is moving.
10.Reinstall the wheel ornament.
1. Put the wheel ornament into posi- tion.
Align the cutout of the wheel orna-
ment with the valve stem as shown. 2. Press hand firmly on one side of wheel ornament and then firmly
tap the other side around the edge
of wheel ornament with the heel
of your hand to snap into place.

CAUTION
Take due care in handling the or-
nament to avoid unexpected per-
sonal injury.
11. Check the air pressure of the re-placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 501 in
Section 8. If the pressure 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 and jack se- curely.
13.Wrap the flat tire in the tire bagand stow temporarily in the lug-
gage compartment. The tire bag
is stored with the jack handle.
As the tire carrier is designed for the
compact spare tire, the standard tire
cannot be stored there.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 501 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.

Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” on page 208 in Section 17.
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
(twowheel drive models)—Turn off the
traction control system to become un-
stuck to allow the tires to spin enough
to remove the vehicle from the obstruc-
tion. (For details, see “Traction control
system (twowheel drive models)” on
page 203 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.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
 Do not race the engine and avoid
spinning the wheels.
 If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice. In consultation with them, have
your vehicle towed using either (a) or

Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.

and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
Twowheel drive models—
(a) Towing with wheel lift type truck
From front—Release the parking brake.

When lifting wheels, take care to en-
sure adequate ground clearance for
towing at the opposite end of the
raised vehicle. Otherwise, the bumper
and/or underbody of the towed vehicle
will be damaged during towing.
From rear—Use a towing dolly under the
front wheels.

Never tow a vehicle with an automatic
transmission from the rear with the
front wheels on the ground, as this
may cause serious damage to the
transmission.

You can purchase a new key at your
Toyota dealer if you can give them the
key number. If your vehicle is equipped
with the engine immobilizer system, the
dealer will also need your master key.
Vehicles with engine immobilizer system—
Even if you lose only one key, contact
your Toyota dealer to make a new key. If
you lose all your master keys, you cannot
make new keys; the whole engine immobi-
lizer system must be replaced.
See the suggestion given in “Keys” on
page 10 in Section 1−2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers can still open the door for you,
using their special tools. If you must
break a window to get in, we suggest
breaking the smallest side window be-
cause it is the least expensive to replace.
Be extremely cautious to avoid cuts from
the glass. Please contact your nearest Toyota
dealer and you can purchase a new
wireless remote control transmitter.
Have the registered identification numbers
of your transmitters deleted from your ve-
hicle by your Toyota dealer as soon as
possible to avoid the possibility of theft or
an accident. Then, have the identification
number of your new transmitter registered.
At the same time, you must bring all of
the remaining transmitters to have them
registered again as well.
You can use the wireless remote control
system with the new transmitter. Contact
your Toyota dealer for detailed information.
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 applied.
2. Pry up the cover with a flathead screwdriver or equivalent.
