These keys work in every lock.
Your vehicle is supplied with two kinds
of keys.
1. Master keys—These keys work in ev- ery lock.
2. Sub key—This key will not work in the glove box and tailgate.
To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the side doors can be locked with-
out a key, you should always carry a
spare key in case you accidentally lock
your keys inside the vehicle.

KEY NUMBER PLATE
Your key number is shown on the plate.
Keep the plate in a safe place such as
your wallet, not in the vehicle.
If you should lose your keys or if you
need additional keys, duplicates can be
made by a Toyota dealer using the key
number.
We recommend writing down the key num-
ber and storing it in a safe place.

Your vehicle is supplied with the two
kinds of keys.
1. Master keys (black)—These keys work in every lock. Your Toyota dealer will
need one of them to make a new key
with a built −in transponder chip.
2. Sub key (gray)—This key will not work in the glove box and tailgate.
A transponder chip for engine immobilizer
system has been placed in the head of
the master and sub keys. These chips are
needed to enable the system to function
correctly, so be careful not to lose these
keys. If you make your own duplicate key,
you will not be able to cancel the system
or start the engine.

NOTICE
When using a key containing a trans-
ponder chip, observe the following
precautions:
When starting the engine, do not
use the key with a key ring resting
on the key grip and do not press
the key ring against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts.
LS12041
When starting the engine, do not
use the key with other transponder
keys around (including keys of oth-
er vehicles) and do not press other
key plates against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts. If
this happens, remove the key once
and then insert it again after remov-
ing other transponder keys (includ-
ing keys of other vehicles) from the
ring or while gripping or covering
them with your hand to start the
engine.

The engine immobilizer system is a
theft prevention system. When you in-
sert the key in the engine switch, the
transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The engine will start only when
the electronic code in the chip corre-
sponds to the registered ID code for
the vehicle.
Never leave the keys inside the vehicle
when you leave the vehicle.
XS12001
The system is automatically set when the
key is removed from the engine switch.
The indicator light will start flashing to
show the system is set.
If any of the following indicator conditions
occurs, contact your Toyota dealer.
The indicator light stays on except
when the theft deterrent system is set-
ting or activating. (See “Theft deterrent
system” on page 39 in this Section.)
The indicator light does not start flash-
ing when the key is removed from the
engine switch.
The indicator light flashes inconsistent-
ly. Inserting the registered key in the engine
switch automatically cancels the system,
which enables the engine to start. The
indicator light will go off.
The system is maintenance−
free.
For your Toyota dealer to make you a
new key with built −in transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the sys-
tem or start the engine.
NOTICE
Do not modify, remove or disas-
semble the engine immobilizer sys-
tem. If any unauthorized changes or
modifications are made, proper opera-
tion of the system cannot be guaran-
teed.

The system can memorize up to 2 posi-
tions by repeating the above steps. If step
2 is performed for a button that already
has a memory setting, the previous posi-
tion will be erased and the new position
will be memorized.
To make only slight changes to an already
memorized position, the easiest way is to
first activate the memorized position, then
make the desired changes and perform
step 2 above.
XS13099a
RECALLING THE MEMORIZED POSITION
When you push button “1” or “2”, a
beep will sound and the driving posi-
tion will be automatically adjusted to
the position recorded for that button.
The memorized position can be recalled
under the following conditions:
The engine switch is in the “ON” posi-
tion and the selector lever is in the “P”
position.
The key is not in the engine switch
and less than 30 seconds have passed
since opening the driver ’s door.
To stop the operation, push any driving
position memory button. To reactivate the system, push button “1”
or “2” again.
If the vehicle’s battery is disconnected,
the memory will be erased and the posi-
tions will have to be set again.
CAUTION
Do not start the vehicle while the
adjustment are being made.
Take care not to select the wrong
button, or the seat could strike the
rear passenger or hit your body
against the steering wheel. If this
happens, you can stop the move-
ment by pressing another driving
position memory switch, or de-
pressing the brake pedal.

The oil pressure gauge indicates engine
oil pressure when the engine 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.

Automatic transmission fluid tempera-
ture gauge indicates automatic trans-
mission fluid temperature when the en-
gine switch is on. Check it while
driving to make sure that the needle is
in the proper range.
The gauge displays the current tempera-
ture of the automatic transmission fluid.
The gauge informs the driver of changes
in the automatic transmission fluid temper-
ature especially if it becomes too high
while towing a heavy trailer or hauling a
heavy load.
If the needle reads high range while you
are driving, slow down and pull off the
road. Stop the vehicle at a safe place and
put the selector lever in “P”. With the
engine idling, wait until the needle reads
below the high range. If the needle reads
below the high range, you may start the
vehicle again. If the needle reads the high
range, call a Toyota dealer or qualified
repair shop for assistance.
NOTICE
Continued driving with reading in the
high range may damage the automatic
transmission.
