NOTElTo prevent the battery from being
discharged, do not leave the trunk open for
a long period when the engine is not
running.
l(Battery saver)
If the lid is left open, the trunk light turns
off after about 30 minutes to prevent battery
depletion.
Inside Trunk Release Lever
Your vehicle is equipped with an inside
trunk release lever that provides a means
of escape for children and adults in the
event they become locked inside the
trunk.
No matter how careful adults might be
with keys and locking their cars, parents
should be aware that children may be
tempted to play around vehicles and use
the trunk as a hiding place.
Adults are advised to familiarize
themselves with the operation and
location of the inside trunk release lever
so that all children can be told about it in
an appropriate way, keeping in mind that
most vehicles do not have such levers.

Theft-Deterrent Systemí
If the theft deterrent system detects an
inappropriate entry into the vehicle, which
could result in the vehicle or its contents
being stolen, the alarm alerts the
surrounding area of an abnormality by
sounding the horn and flashing the hazard
warning lights.
Refer to Operation on page 3-62.
NOTE
lThe theft-deterrent system operates with the
key or the keyless entry system transmitter.
l(With advanced key)
The theft-deterrent system can also be
operated using the advanced keyless
function.
The system operates only when the driver is
in the vehicle or within operational range
while the advanced key is being carried.
lThe system will not function unless it is
properly armed. To properly secure the
vehicle, always make sure all windows are
completely closed and all doors and the
trunk lid/liftgate are locked before leaving
the vehicle. Remember to take your key and
transmitter.
qOperation

deactivated by pressing the request switch
on a door.

Ignition Switch
With advanced key
Refer to“Starting the engine (page 3-12) ”
for information on how to use the ignition
switch.
q Ignition Switch Positions
(Without Advanced Key)
The engraved mark on the actual vehicle
may read OFF or LOCK depending on the
type of ignition system.
OFF/LOCK
The power supply to electrical devices is
turned off. Only in this position can the
key be removed.
WARNING
Remove the key only when the vehicle
is parked (with steering lock
mechanism):
Removing the key from the ignition
switch while the vehicle is moving is
dangerous. Removing the key allows
the steering wheel to lock. You will
lose steering control and a serious
accident could occur.
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the shift lever is
in P (automatic transaxle) or in 1st gear
or R (manual transaxle): Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the shift
lever to P (automatic transaxle) or to
1st gear or R (manual transaxle) is
dangerous. Unexpected vehicle
movement could occur which could
result in an accident.
In addition, if your intention is to
leave the vehicle for even a short
period, it is important to switch the
ignition off, as leaving it in another
position will disable some of the
vehicle's security systems and run the
battery down.
NOTE
If turning the key is difficult, move the steering
wheel left and right.
Leaving the key in any position but the OFF/
LOCK position also disables some of the
security features and may run the battery
down.
ACC (Accessory)
In this position, some electrical
accessories will operate.
