wheel block in front of one of the front
wheels or behind one of the rear
wheels.

3. Loosen all the wheel nuts.
Always loosen the wheel nuts before
raising the vehicle.
Turn the wheel nuts counterclockwise
to loosen them. To get maximum le-
verage, fit the wrench to the nut so
that the handle is on the right side,
as shown above. Grab the wrench
near the end of the handle and pull
up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet—just un-
screw them about one −half turn in the
order shown.

5. After making sure no one is in the vehicle, raise it high enough
so that the spare tire can be
installed.
Remember you will need more ground
clearance when putting on the spare
tire than when removing the flat tire.
To raise the vehicl e, insert the jack
handle into the jack (it is a loose fit)
and turn it clockwise. As the jack
touches the vehicle and begins to lift,
double −check that it is properly posi-
tioned.

back over the other bolts.
50p017c
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-

cause wheel nuts to loosen and even-
tually cause a wheel to come off while
driving.

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 loosen 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.

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.
—Reinstalling wheel nuts —Lowering your vehicle

373
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.

curely. Then secure the flat tire
in the luggage compartment
with the tire tiedown belts and
tiedown hooks as follows

reduce the possibility of person-
al injury during a collision or
sudden braking.

placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 434. If the
pressure is lower than specified, drive
slowly to the nearest Toyota dealer

(a) Towing with wheel lift type truck——From front
—From rear
(b) Using flat bed truck If towing is necessary, we recommend
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
(b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in “—Emergency tow-
ing” on page 377.
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. TOWING PRECAUTIONS:
Use a safety chain system for all towing,
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.
(a) Towing with wheel lift type truck
From front
—Release the parking brake.
NOTICE
When lifting wheels, take care to en-
sure adequate ground clearance for
towing at the opposite end of the
raised vehicle. Otherwise, the under-
body of the towed vehicle will be
damaged during towing.
From rear—Use a towing dolly under the
front wheels.
NOTICE
Never tow a vehicle from the rear
with the front wheels on the ground,
as this may cause serious damage to
the transmission.
(b) Using flat bed truck
If your vehicle needs to be
towed—

(c) Towing with sling type truck
(c) Towing with sling type truck
NOTICE
Do not tow with sling type truck, ei-
ther from the front or rear. This may
cause body damage.
50p035b
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to emergency towing eyelet in-
side of front bumper. Use extreme
caution when towing vehicles.
NOTICE
 Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
 Never tow a vehicle from the rear
with four wheels on the ground.
This may cause serious damage to
the transaxle.
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.
—Emergency towing

378
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 hybrid transaxle in “N”. The
hybrid system must be in the “IG−ON”
mode.
In the following cases, as the front wheels
might be locked by means of the parking
lock mechanism, your vehicle cannot be
towed by another vehicle using a rope.
Have your vehicle carried with the front
wheels or all the wheels raised.
If the parking mechanism fails.
If the 12 volt battery is discharged.
CAUTION
If the hybrid system is not running,
the power assist for the brakes and
steering will not work so steering and
braking will be much harder than usu-
al.
