faces up to avoid scratching the wheel
surface.
1 Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen while the vehicle is in motion, causing the tire to come off.
2 Install the tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.
Turn the wheel nuts until the washers come into contact with the disc wheel.

WARNING
■Replacing a tire
●Observe the following precautions.
Failure to do so may result in serious
injury:
Do not touch the disc wheels or the
area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the
disc wheels and the area around the
brakes will be extremely hot. Touch-
ing these areas with hands, feet or
other body parts while changing a tire,
etc., may result in burns.
●Failure to follow these precautions
could cause the wheel nuts to loosen and the tire to fall off, result-ing in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5
kgf•m, 76 ft•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifi-cally designed for that wheel.
• If there are any cracks or deforma- tions in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

3Lower the vehicle.
4 Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque: 103 N•m (10.5 kgf•m, 76 ft•lbf)
5 Stow the tire jack and all tools.
■After completing the tire change
The tire pressure warning system must be reset. ( P.280)
Tire inflation pressure is specified
on the label on the driver’s side
door frame as shown.
Left-hand drive vehicles
Right-hand drive vehicles
WARNING
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their
storage location to reduce the possi- bility of personal injury during a colli-sion or sudden braking.
Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( P. 3 5 5 )

Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drive train
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Instructions for checking tire infla-tion pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation pressure reading.
●Always use a tire pressure gauge.It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
WARNING
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire dam-age
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.

6-4. Do-it-yourself maintenance
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be
installed. ( P.279)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a differ-
ent size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leak-ing wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or serious injury.
■When installing the wheel nuts
Never use oil or grease on the wheel
bolts or wheel nuts. Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and
the wheel may fall off, causing an accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
■Use of defective wheels prohib-ited
Do not use cracked or deformed
wheels. Doing so could cause the tire to leak air during driving, possibly causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. In addition, make sure to purchase your tire pressure warn-
ing valves and transmitters at any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.

■When replacing light bulbs
Toyota recommends that you use genu- ine Toyota products designed for this vehicle.
Because certain bulbs are connected to circuits designed to prevent overload, non-genuine parts of parts not designed
for this vehicle may be unusable.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions. Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
●Never use a fuse of a higher
amperage rating than that indi- cated, or use any other object in place of a fuse.
●Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
●Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload
determined and repaired by any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
■When installing the fuse box cover (Engine compartment)
Press the fuse box cover, when
installing, after aligning all of the claw positions. Otherwise, the claws may be damaged.

WARNING
■Replacing light bulbs
●Tur n o ff t h e li g ht s. D o n o t at t e mp t t o replace the bulb immediately after turning off the lights. The bulbs
become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. When it is unavoidable to hold the
glass portion, use and hold with a clean dry cloth to avoid getting moisture and oils on the bulb. Also,
if the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so may result in heat damage,
fire, or water entering the light unit. This may damage the lights or cause condensation to build up on
the lens.
■To prevent damage or fire
Make sure bulbs are fully seated and locked.
