TESTING THE SYSTEM
1. Open all the windows.
2. Set the system as described above.
The side doors and back door should
be locked with the key or wireless re-
mote control transmitter. Be sure to
wait until the indicator light starts flash-
ing.
3. Unlock any door from the inside. The
system should activate the alarm.
4. Stop the alarm as described above.
5. Repeat this operation for the other
doors and hood. When testing the
hood, also check that the system is
activated when the battery terminal is
disconnected and then reconnected.
If the system does not work properly,
have it checked by your Toyota dealer.
This indicates that the fuel filler door
is on the left side of your vehicle.1. To open the fuel filler door, pull the
lever up.
When refueling, turn off the engine.
CAUTION

Do not smoke, cause sparks or al-
low open flames when refueling.
The fumes are flammable.

When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re-
moved.

To turn on the seat heater, push the
switches (Lº switch for the left front
seat and Rº switch for the right front
seat). At this time, the indicator light
will illuminate to indicate the seat heat-
er is operating.
To turn off the seat heater, push the
switch once again.
The key must be in the ONº position to
operate seat heaters.
CAUTION
Occupants must use caution when op-
erating the seat heater because it
may make them feel too hot or cause
burns at low temperatures (erythema,
varicella). Use extra caution for;

Babies, small children, elderly per-
sons, sick persons or persons with
physical disabilities

Persons who have delicate skin

Persons who are exhausted

Persons who have taken alcohol or
drugs which induce sleep (sleeping
drug, cold remedy, etc.)
To prevent the seat overheating, do
not use the seat heater with a blan-
ket, cushion, or other insulating ob-
jects which cover the seat.
NOTICE

Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.

When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.

To prevent the battery from being
discharged, turn the switch off
when the engine is not running.
