Do not touch or move any compo-
nents inside of the transmitter, or
it may interfere with proper opera-
tion.
 Be careful not to bend the electrode
of the transmitter battery insertion
and that dust or oils do not adhere
to the transmitter case.
 Close the transmitter case securely.
After replacing the battery, check that the
transmitter operates properly. If the trans-
mitter still does not operate properly, con-
tact your Toyota dealer.
Locking operation
Unlocking operation
The wireless remote control system is
designed to lock or unlock all the
doors or activate the “PANIC” mode
from a distance within approximately 1
m (3 ft.) of the vehicle.
LOCKING AND UNLOCKING THE

doors are locked simultaneously. At this
time one beep will be heard, and the
parking lights and tail lights flash once.
Check to see that all the doors are se-
curely locked.
If any of the doors is not securely closed,
locking cannot be performed by the
“LOCK” switch and a beep will sound con-
tinuously for 10 seconds. However, if the
key is in the ignition, a beep will not
sound.
To stop the beep, close all the doors se-
curely or push the “UNLOCK” switch.
The beep can be disabled. For details,

The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop −and− go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” in Section 4.
IdlingNormal
driving
The oil pressure gauge indicates engine
oil pressure when the ignition switch is
on. Check it while driving to make sure
that the needle is in the proper range.
If the oil pressure should stay below the
normal range, pull off the road to a safe
place and stop the engine immediately.
Call a Toyota dealer or qualified repair
shop for assistance.
Oil pressure may not build up when the
oil level is too low. The oil pressure
gauge is not designed to indicate oil level,
and the oil level must be checked using
the level dipstick.

NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed—it may ruin the
engine.
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
