Tires and loading on yourTo y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 398 and 471.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.

needs to be initialized. Reset the system
with the tire pressure warning system re-
set switch. (To reset the system, see
“TIRE PRESSURE WARNING SYSTEM
RESET SWITCH”.)
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
The tread wear is uneven among the
tires.
A compact spare tire, snow tires, or
tire chains are used.
The tire inflation pressure is excessive-
ly higher than specified, or tire inflation
pressure suddenly drops due to burst-
ing or other causes.
The vehicle is driven on a slippery
road surface such as rough or frozen
roads.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
The tires differ in tread pattern or
manufacturer.
The tires are not the specified size.
The tread wear is very different among
the installed tires.
The pressure of two or more tires
drops at the same time.
Rapid acceleration/deceleration or
sharp turns is continue.
Towing a trailer.
The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
Vehicles with vehicle stability control
system—The outside temperature is be-
low 0 C (32F) or above 40 C (104 F).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Vehicles with the standard tires—
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
Vehicles with the runflat tires—
Decelerate as soon as possible to
the lowest appropriate speed that
conditions permit. Do not drive for
longer than 160 km (100 miles) or
over 90 km/h (55 mph).
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.

Note: The tire pressure warning sys-
tem on your vehicle will warn you
when one of your tires is significantly
underinflated and when some com-
binations of your tires are significant-
ly underinflated. However, there are
other combinations of significantly
underinflated tires for which your
tire pressure warning system may not
warm you. These other combinations
are relatively common, accounting for
approximately half the instances in
which vehicles have significantly un-
derinflated tires. For example, your
system may not warm you when both
tires on the same side or on the
same axle of your vehicle are signifi-
cantly underinflated. It is particularly
important, therefore, for you to check
the tire pressure in all of your tires
regularly and maintain proper pres-
sure.
TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system need
to be initialized in the following condi-
tions:
When the low tire pressure warning
light blinks twice every second
After replacing or rotating tires or
wheels
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard. To initialize the system, perform the fol-
lowing:
1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.
2. Adjust the pressure of all the installed tires to the specified level. (See “Tires”
on page 501 in Section 8.)
3. Turn the ignition key to “ON”. Vehicles with vehicle stability control
system only—If the low tire pressure
warning light comes on, push the reset
switch for a few seconds and make
sure the warning light goes off.
4. Push and hold the reset switch until the low tire pressure warning light
blinks three times.
Vehicles without vehicle stability control
system—Initialization is completed after
driving at the speeds of 30 km/h (19 mph)
or over for about 8 hours total, when the
tire pressure warning system detects the
normal tire pressure.
