ors, warning light, ªRSCA OFFº indicator
light, interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.

ignition key is turned to the ªONº posi-
tion or remains on for more than 6
seconds.

NOTICE
Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected by
the installation or removal of tires.
The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
When the tires must be replaced,
replace the grommets for air pres-
sure sensors as well.
If the warning light blinks:
The tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
SYSTEM MALFUNCTION
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.
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
A radio set to similar frequencies is in
use.
A lot of snow or ice covers the ve-
hicle, in particular, around the wheels
or wheel housings.
The tires are not equipped with an air
pressure sensor.
Snow tires or tire chains are used.
Non±genuine Toyota wheels are used.
The sensor battery is expired.
Radio waves from the air pressure sen-
sor installed on the spare tire cannot
be received.
CAUTION
The use of non±genuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
The use of different type of tires
with genuine wheels may also
cause the malfunction of the sys-
tem.

frequency energy and, if not installed
and used in accordance with the instruc-
tions, may cause harmful interference to
radio communications. However, there is
no guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful interfer-
ence to radio or television reception,
which can be determined by turning the
equipment off and on, the user is en-
couraged to try to correct the interfer-
ence by one or more of the following
measures:Reorient or relocate the receiving an-
tenna.
Increase the separation between the
equipment and receiver.
Connect the equipment into an outlet
on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced
radio/TV technician for help.

For vehicles sold in Canada
Operation is subject to the following two
conditions:
(1) this device may not cause interfer-
ence, and (2) this device must accept
any interference, including interference
that may cause undesired operation of
the device.
When replacing the wheels, be sure to
install air pressure sensors on the
wheels.
There are 3 ways to set up the air pres-
sure sensors:
a. Remove the sensor from the old wheel
and install it to the new wheel.
b. Keep the same wheel with air pressure
sensor and replace only the tire.
c. Use a new wheel and sensor. In this
case, you have to register an ID code
for a new sensor.
CAUTION
Have the tires, wheels or sensors re-
placed and ID codes registered by a
Toyota dealer. If you need sensors,
purchase from a Toyota dealer.

1. Outside temperature
The outside temperature display indi-
cates the outside air temperature.
The displayed value is updated every 1
second.
The displayed temperature ranges from
±30C (±22F) up to 50C (122F).
If an abnormality exists in the connection
of the outside air temperature sensor,
ª±±Cº (ª±±Fº) will appear on the display.
If ª±±Cº (ª±±Fº) appears on the display,
contact your Toyota dealer.
There may be a case that ª±±Cº (ª±±Fº)
appears momentarily when the ignition is
quickly turned to ªONº. It is normal if it
goes out soon.
2. Average fuel consumption
(ªAVGº)
Average fuel consumption is calculated
and displayed based on total driving
distance and total fuel consumption
with the engine running.
The displayed value is updated every 1
seconds.
To reset the calculations, return the mode
to ªAVGº and push and hold the ªMODEº
and ªE/Mº button simultaneously for 2 sec-
onds.3. Instantaneous fuel consumption
(ªINSTº)
The instantaneous fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption for 1 sec-
onds with the engine running.
The displayed value is updated every 1
seconds.
Note that an accurate figure may not be
shown in the following cases.
The vehicle is stopped with the engine
running. (The display will indicate the
extremely high fuel consumption.)
The vehicle is driving down a long
slope, applying the engine brake. (The
display will indicate the extremely low
fuel consumption.)
The calculation is reset when the ignition
switch is turned off.
4. Distance to empty
(ªDTEº)
The distance the vehicle can travel with
the remaining fuel is calculated and
displayed based on the quantity of re-
maining fuel and past fuel consumption.
The displayed value is updated every 1
second.Every time you refuel the vehicle, the cal-
culation is reset.
The actual driving range varies with driv-
ing habits and road conditions. If fuel con-
sumption is good, the driving range will be
longer than indicated. If fuel consumption
is poor, the driving range will be shorter
than indicated.

Compass sensor
The compass sensor is on the inside of
the roof.
NOTICE
Do not put magnets or a metal object
on or near the roof of the vehicle.
Doing this may cause malfunction of
the compass sensor.
CALIBRATING THE COMPASS (deviation
calibration)
The direction display on the compass
deviates from the true direction deter-
mined by the earth's magnetic field. The
angle of deviation varies according to the
geographic position of the vehicle.
To adjust for this deviation;
1. Stop the vehicle in a level place and
switch the display to the outside tem-
perature. (To switch to this mode, see
ªÐOutside temperature and cruise in-
formation displayº on page 307 in this
Section.)
2. Push and hold both the ªMODEº and
ªE/Mº buttons simultaneously for 5 sec-
onds until the ªVARº indication appears
on the compass display.
3. Push the ªE/Mº button several times
until the desired zone number appears
on the compass display.
If the button is not pushed for 10 sec-
onds, the display returns to the compass/
outside temperature mode and the number
that is last set is memorized.
To select the zone where the vehicle is
currently located, refer to the following
map.

Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti±lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels' turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

ªABSº warning light
The light comes on when the ignition key
is turned to the ªONº position. If the anti±
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system, the brake assist
system and the traction control system
and/or the vehicle stability control system
do/does not operate, but the brake system
still operates conventionally.
When the ªABSº warning light is on (and
the brake system warning light is off), the
anti±lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
