Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however, they
do not make it impossible to steal.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
This is the security light.To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE) transmitter. The security light should come
on and flash.
If the delayed locking feature is active, the alarm
will not be activated until all doors are closed and
the security light goes off.
3. Close all doors. The security light will stop flashing and go off after approximately 30 seconds. The
content theft deterrent alarm is not armed until the
security light goes off.
If a locked driver door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The horn
will chirp and the lights will flash. If the key is not placed
in the ignition and turned to START or the door is not
unlocked by pressing the unlock button on the RKE
transmitter during the ten second pre-alarm, the alarm
will go off. Your vehicle's headlamps will flash and the
horn will sound for about 30 seconds, then will turn off
to save the battery power.
3-17
The theft-deterrent system will not activate if the doors
are locked with the vehicle's key or the manual door
lock. It activates only if you use the power door lock
switch with the door open or the RKE transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by accident:
.If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
.Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.
If you set off the alarm by accident, press unlock on the
RKE transmitter or place the key in the ignition and turn
it to START to turn it off.
Testing the Alarm
To test the alarm: 1. From inside the vehicle, lower the driver's window and open the driver's door.
2. Activate the system by locking the doors with the RKE transmitter.
3. Get out of the vehicle, close the door and wait for the security light to go out.
4. Then reach in through the window, unlock the door with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should but the
headlamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see Fuses and Circuit Breakers on page 6‑118.
If the alarm does not sound or the headlamps do not
flash, see your dealer/retailer for service.

Park Tilt Mirrors
If the vehicle has the memory package, the passenger
and/or driver mirror tilts to a preselected position when
the vehicle is in R (Reverse). This feature lets the driver
view the curb when parallel parking. The mirror(s) return
to the original position when the vehicle is shifted out of
R (Reverse), or the ignition is turned off or to
OFF/LOCK.
Turn this feature on or off through the Driver Information
Center (DIC). SeeDIC Vehicle Customization (With DIC
Buttons)
on page 4‑75for more information.
Outside Convex Mirror
{WARNING:
A convex mirror can make things, like other
vehicles, look farther away than they really are.
If you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror's surface is curved so more can be seen from the
driver seat.
Outside Heated Mirrors

.If small heavy objects are placed on the roof, cut a
piece of 3/8 inch plywood to fit inside the crossrails
and siderails to spread the load. Tie the plywood to
the siderail supports.
.Tie the load and secure it to the crossrails or the
siderail supports. Use the crossrails only to keep
the load from sliding. To move a crossrail, lift the
release lever up, on both sides of the rail. Then
slide the crossrail to the desired position balancing
the force side to side. Press the release lever
down on both sides of the rail, down to tighten it.
Try to slide the crossrail back and forth slightly to
make sure it is tight.
.To carry long items, move the crossrails as far
apart as possible. Tie the load to the crossrails and
the siderails or siderail supports. Also tie the load
to the bumpers, but do not tie the load so tightly
that the crossrails or siderails are damaged.
.After moving a crossrail, be sure it is securely
locked into the siderail. A Center High-Mounted Stoplamp (CHMSL) is located
above the rear window glass.
Make sure items loaded on the roof of the vehicle do
not block or damage the CHMSL.

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery's temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery's state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer loads,
and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's output
and the vehicle's electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the highest
levels of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as BATTERY
SAVER ACTIVE, BATTERY VOLTAGE LOW, or
LOW BATTERY. If this message is displayed, it is
recommended that the driver reduce the electrical loads
as much as possible. See
DIC Warnings and Messages
on page 4‑65.
Battery Run-Down Protection
This feature shuts off the dome and reading lamps,
if they are left on for more than 10 minutes after the
ignition is turned off. The cargo lamp shuts off after
20 minutes. This prevents the battery from
running down.
