Maintenance and care
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
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 pres-
sure. Whenever wheels are
replaced, tire pressure warning
valves and transmitters must be
installed. ( P.476)
Wheels
If a wheel is bent, cracked
or heavily corroded, it
should be replaced. Other-
wise, the tire may separate
from the wheel or cause a
loss of handling control.

WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended in the Owner’s Manual,
as this may result in a loss of
handling control.
●Never use an inner tube in a
leaking wheel which is designed
for a tubeless tire. Doing so may
result in an accident, causing
death or serious injury.
■Wheel bolts
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Do not over tighten.
●Never use oil or grease on the
wheel bolts. Oil and grease may
cause the wheel bolts to be
excessively tightened, leading
to bolt or disc wheel damage. In
addition, the oil or grease can
cause the wheel bolts to loosen
and the wheel may fall off, caus-
ing a serious accident. Remove
any oil or grease from the wheel
bolts.
●If there are any cracks or defor-
mations in the wheel bolts, or if
the surface treatment becomes
worn, have the wheel bolts
replaced at your Toyota dealer.
Failure to follow these precau-
tions could cause the wheel
bolts to loosen and the tire to fall
off, resulting in death or serious
injury.
■Use of defective wheels pro-
hibited
Do not use cracke d or deformed
wheels.
Doing so could cause the tire to
leak air during driving, possibly
causing an accident.

Maintenance and care
Adjustment bolt A
Adjustment bolt B
Make sure the vehicle has a
full tank of gasoline and the
area around the headlight is
not deformed.
Park the vehicle on level
ground.
Make sure the tire inflation
pressure is at the specified
level.
Have someone sit in the
driver’s seat.
Bounce the vehicle several
times. 1
Using a Phillips-head screw-
driver, turn bolt A in either
direction.
Remember the turning direc-
tion and the number of turns.
2 Turn bolt B the same number
of turns and in the same
direction as step 1.
If the headlight cannot be adjusted
using this procedu re, take the vehi-
cle to your Toyota dealer to adjust
the headlight aim.

When trouble arises
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner’s manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle
movement during transporta-
tion, set the parking brake and
turn the power switch off.
If a tow truck is not available in
an emergency, your vehicle may
be temporarily towed using
cables or chains secured to the
emergency towing eyelets. This
should only be attempted on
hard surfaced roads for short
distances at under 18 mph (30
km/h).
A driver must be in the vehicle to
steer and operate the brakes.
The vehicle’s wheels, drive train,
axles, steering and brakes must
be in good condition.
WARNING
AWD models
Be sure to transport the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires contacting the
ground, the drivetrain or related
parts may be damaged, the vehi-
cle may fly off the truck, or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending on the nature of
the damage or malfunction.
NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
When raising the vehicle, ensure
adequate ground clearance for
towing at the opposite end of the
raised vehicle. Without adequate
clearance, the vehicle could be
damaged while being towed.
■Towing with a sling-type truck
Do not tow with a sling-type truck
to prevent body damage.

mal.)

WARNING
■While towing
●When towing using cables or
chains, avoid sudden starts,
etc., which place excessive
stress on the towing eyelets,
cables or chains. The towing
eyelets, cables or chains may
become damaged, broken
debris may hit people, and
cause serious damage.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the front
wheels and possibly leading to
an accident resulting in death or
serious injury:
• Unfasten the driver’s seat belt and open the driver’s door.
• Turn the power switch off.
■Installing towi ng eyelets to
the vehicle
Make sure that towing eyelets are
installed securely. If not securely
installed, towing eyelets may
come loose during towing.
NOTICE
■To prevent damage to the
vehicle during emergency
towing
Do not secure cables or chains to
the suspension components.
If you think something
is wrong
If you notice any of the fol-
lowing symptoms, your
vehicle probably needs
adjustment or repair. Con-
tact your Toyota dealer as
soon as possible.

■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P. 5 2 7
If none of the tires are punctured:
Turn the power switch off then turn it
to ON. Check if th e tire pressure
warning light com es on or blinks.
If the tire pressure warning light
blinks for approximately 1 minute
then stays on
There may be a malfunction in the
tire pressure warning system. Have
the vehicle inspected by your Toyota
dealer immediately.
If the tire pressur e warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation pressure of each tire
and adjust them to the specified
level.
2 If the warning light does not turn
off even after several minutes
have elapsed, check that the
inflation pressure of each tire is
at the specified level and perform
the tire inflation pressure setting
procedure. ( P.483)
If the warning light d oes not turn off
even after several minutes have
elapsed since performing the tire
inflation pressure setting proce-
dure, have the vehicle inspected by
your Toyota dealer as soon as pos-
sible.

as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this case, adjusting the
tire inflation pressure will turn off the
warning light (after a few minutes).
■Conditions that the tire pres-

P. 4 7 4
WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your Toy-
ota dealer.
The vehicle will become
extremely unstable during brak-
ing, and the ABS system may fail,
which could cause an accident
resulting in death or serious injury.
■When the electric power
steering system warning light
comes on
When the light comes on yellow,
the assist to the power steering is
restricted. When the light comes
on red, the assist to the power
steering is lost and handling oper-
ations of the steering wheel
become extremely heavy.
When steering wheel operations
are heavier than usual, grip the
steering wheel firmly and operate
it using more force than usual.
■If the tire pressure warning
light comes on
Be sure to observe the following
precautions.
Failure to do so could cause a
loss of vehicle control and result
in death or serious injury.
●Stop your vehicle in a safe place
as soon as possible. Adjust the
tire inflation pressure immedi-
ately.
●If the tire pressure warning light
comes on even after tire infla-
tion pressure adjustment, it is
probable that you have a flat
tire. Check the tires. If a tire is
flat, repair the flat tire by using
emergency tire puncture repair
kit.
●Avoid abrupt maneuvering and
braking.
If the vehicle tires deteriorate,
you could lose control of the
steering wheel or the brakes.
■If a blowout or sudden air
leakage should occur
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
Each tire, includi ng the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label (tire and
load information label). (If your
vehicle has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)
