46 Keys, Doors, and Windows Power Sounder, Inclination
Sensor, and Intrusion Sensor In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder, inclination sensor, and
intrusion sensor.
The power sounder provides an
audible alarm, which is distinct from
the vehicle ’ s horn. It has its own
power source, and can sound an
alarm if the vehicle ’ s battery is
compromised.
The inclination sensor can set off
the alarm if it senses movement of
the vehicle, such as a change in
vehicle orientation.
The intrusion sensor monitors the
vehicle interior, and can activate the
alarm if it senses unauthorized entry
into the vehicle ’ s interior. Do not
allow passengers or pets to remain
in the vehicle when the intrusion
sensor is activated. Before arming the theft-deterrent
system and activating the intrusion
sensor:
.
Make sure all doors and
windows are completely closed.
.
Secure any loose items such as
sunshades.
.
Make sure there are no
obstructions blocking the
sensors in the front overhead
console.
Inclination and Intrusion
Sensors Disable Switch It is recommended that the intrusion
and inclination sensors be
deactivated if pets are left in the
vehicle or if the vehicle is being
transported. With the vehicle turned off, press
o in the front overhead console.
The indicator light will come on
momentarily, indicating that these
sensors have been disabled for the
next alarm system arming cycle.

176 Lighting Entry Lighting with Approach
Detection
If equipped with approach detection,
the entry lighting feature will
automatically turn on when the RKE
transmitter is detected within
approximately 2 m (6 ft) of the
vehicle.
If the vehicle has remained parked
for an extended period of time with
no RKE transmitter use or Keyless
Access operation, approach
detection will be disabled. To
reactivate, press any button on the
RKE transmitter or open and close
all vehicle doors to re-enable the
entry lighting feature on approach.
Exit Lighting Some exterior lamps and interior
lights come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off. The dome lamp comes
on after the ignition is changed to
the OFF position. The exterior
lamps and dome lamp remain on for
a set amount of time, then
automatically turn off. The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization 0 157 .
Battery Power Protection The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position. To keep the lamps on for more than
10 minutes, the ignition must be in
the ACC/ACCESSORY or ON/RUN
position.
