REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered on the tire pressure warning
ECU. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
If the ID code is not registered, the sys-
tem will not work properly. After about 1
hour, the tire pressure warning light blinks
to indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.

Tire pressure warning reset switch
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
When rotating the tires on vehicles dif-
fering with front and rear tire inflation
pressures.
When changing the tire inflation pres-
sure by changing traveling speed or
load weight, etc.
When changing the tire size.

To initialize the system, perform the fol-
lowing:1. Park the vehicle in a safe place and the engine is off.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
354.)
3. Turn the ignition switch to the “ON” position.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for a few minutes with the ignition switch “ON”, and then turn the ignition
switch to the “OFF” position.
If you push the tire pressure reset switch
while the vehicle is moving, initialization is
not performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.
16c522a
If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Toyota dealer.
CAUTION
Do not push the reset switch without
first adjusting the tire inflation pres-
sure to the specified level. Other-
wise, the tire pressure warning light
may not come on even if the tire
inflation pressure is low, or it may
come on when the tire inflation pres-
sure is actually normal.

7. “TUBELESS” or “TUBE TYPE”
—A tubeless tire does not have a
tube inside the tire and air is direct-
ly filled in the tire. A tube type tire
has a tube inside the tire and the
tube maintains the air pressure.

quality grading” that follows.
9. Load limit at maximum cold tire inflation pressure— For details,
see “Checking and replacing tires”
on page 333.
10. Maximum cold tire inflation pressure— This means the pres-
sure to which a tire may be in-
flated. For recommended cold tire
inflation pressure, see “Tires” on
page 354.

MATCHING TRAILER BALL HEIGHT TO
TRAILER COUPLER HEIGHT
No matter which class of tow hitch ap-
plies, for a safe trailer hookup, the trailer
ball setup on must be the proper height
for the coupler on the trailer.
BRAKES AND SAFETY CHAINS
Toyota recommends trailers with
brakes that conform to any applica-
ble federal and state/provincial regu-
lations.
A safety chain must always be used
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain should
cross under the trailer tongue to
prevent the tongue from dropping to
the ground in case it becomes dam-
aged or separated. For correct safety
chain procedures, follow the hitch or
trailer manufacturer ’s recommenda-
tions.
CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
braking effectiveness.
Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.
TIRES
Ensure that your vehicle’s tires are
properly inflated. Adjust the tire infla-
tion pressure indicated below:
tire inflation pressure, kPa (psi)Front 220 (32)
Rear 240 (35)
See Section 7 −2 and Section 8 for in-
structions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.
