Your vehicle is supplied with two kinds
of keys.1. Master key—This key works in every lock.
2. Sub key—This key will not work in the glove box.
To protect things locked in the glove box
when you have your vehicle parked, leave
the sub key with the attendant.
Since the front doors and sliding doors
can be locked without a key, you should
always carry a spare master 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 you to write down the key
number and keep it in safe place.Your vehicle is supplied with two kinds
of keys. 1. Master key (black)—This key works in every lock. Your Toyota dealer will
need it to make you a new key with
built in transponder chip.
2. Sub key (gray)—This key will not work in the glove box.
A transponder chip for engine immobiliser
system has been filled 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.

To protect things locked in the glove box
when you have your vehicle parked, leave
the sub key with the attendant.
Since the front doors and sliding doors
can be locked without a key, you should
always carry a spare master key in case
you accidentally lock your keys inside the
vehicle.
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.
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 taking
off 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.

ly.

hicle. Along with the proper use of
seat belts, locking the doors helps
prevent the driver and passengers
from being thrown out from the ve-
hicle during an accident. It also helps
prevent the doors from being opened
unintentionally.

Vehicles with power door lock sys-
tem—The sliding doors will be locked si-
multaneously when either front door or the
back door is locked with the power door
lock switch or key. If you lock either front
door or the back door with the power door
lock switch or key while the sliding door
is open, the sliding door will be locked
after it is closed. (For instructions, see
“Front doors” or “Back door” in this sec-
tion.)
Closing the sliding door with the lock knob
in the lock position will also lock the slid-
ing door. Be careful not to lock your keys
in the vehicle.
CLOSING FROM INSIDE
To close the fully opened sliding door,
push the lock release button and then
close the door.
CAUTION
When closing the sliding door, con-
firm safety of the area around.
Keep the heads, hands and other
parts of the bodies of all occupants
away from the sliding door. Other-
wise, they will be possibly caught
and pinched by the closing door
causing an unexpected serious inju-
ry.
When the vehicle is stopped on a
gradient, the door will slide faster
when opening or closing, so be es-
pecially careful that the passengers
do not get hit or pinched by the
door.
When stopping on a downward
slope, open the door fully while
passengers are getting on or off.
Do not pull the outside handle or
push the lock release button while
the door is open as the door could
suddenly close by itself causing in-
jury.
NOTICE
Do not close the sliding door by ap-
plying the brakes. Doing so could
cause the door to be damaged.
