These keys work in every lock.
Since the doors can be locked without a
key, you should always carry a spare key
in case you accidentally lock your key
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

We recommend writing down the key num-
ber and storing it in a safe place.LOCKING AND UNLOCKING WITH KEY

The remote keyless entry 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
To lock and unlock all the doors, push
the switches of the transmitter slowly
and securely.
To lock: Push the “LOCK” switch. All the
doors are locked simultaneously. At this
time one beep will be heard, and the tail
lights and front side marker lights will
flash once.
Check to see that the doors are securely
locked.
If any door is not securely closed, locking
cannot be performed by the “LOCK”
switch and a beep will sound continuously
for 5 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. To unlock: Push the “UNLOCK” switch
once to unlock the driver’s door alone.
Pushing the switch twice within 3 seconds
unlocks all the doors simultaneously. Each
time the “UNLOCK” switch is pushed, two
beeps will be heard, and the tail lights
and front side marker lights will flash
twice.
When the “UNLOCK” switch is pressed,
the interior light and ignition switch light
come on. The lights remain on for about
30 seconds unless any door is opened
and closed.
You have 30 seconds to open a door after
using the wireless remote unlock feature.
If a door is not opened by then, all the
doors will be automatically locked again
and one beep will be heard, and the tail
lights and front side marker lights will
flash once.
If the “LOCK” or “UNLOCK” switch is kept
pressed in, the locking or unlocking opera-
tion is not repeated. Release the switch
and then push again.
“PANIC” SWITCH
Pushing the “PANIC” switch blows the
horn intermittently, flashes the head-
lights and tail lights, and turns on the
interior light.
The “PANIC” switch is used to deter ve-
hicle theft when you witness anyone at-
tempting to break into or damage your
vehicle.
The alarm will last for one minute. To stop
alarm midway, push the “PANIC” switch
once again, lock or unlock any door with
the key or transmitter, or turn the ignition
key from the “LOCK” to “ON” position.
The “PANIC” mode does not work when
the ignition key is in the ignition switch.
