DESCRIPTION
DESCRIPTION - POWER LOCK SYSTEM
A power operated door and liftgate lock system is
standard factory-installed equipment on this model.
The power lock system allows all of the doors and the
liftgate to be locked or unlocked electrically by oper-
ating a switch on either front door trim panel. The
power lock system receives non-switched battery feedthrough a fuse in the Power Distribution Center
(PDC), so that the power locks remain operational,
regardless of the ignition switch position.
The power lock system for this vehicle also has a
door lock inhibit feature, which prevents the power
lock system from being energized with a power door
lock switch if a front door is open with the key in the
ignition. However, the locks can still be operated
manually, with a key, energized with the RKE trans-
mitter or by sliding the door lock lever to the appro-
priate position.

POWER MIRRORS
DESCRIPTION
Driver and passenger side power operated outside
rear view mirrors are standard factory-installed
equipment on this model. The power mirror system
allows the driver to adjust both outside mirrors elec-
trically from the driver seat position by operating a
switch on the driver side front door trim panel. The
power mirror system receives non-switched battery
current through a fuse in the Power Distribution
Center (PDC) so that the power mirrors remain oper-
ational, regardless of the ignition switch position.
The standard equipment power operated outside
rear view mirrors are also equipped with the heated
mirror system, which will only operate when the
ignition switch is in the On position and the rear
window defogger switch is turned on. When the rear
window defogger switch is in the On position, electric
heater grids on the rear window glass and behind
both outside rear view mirror glasses are energized.
These electric heater grids produce heat to help clear
the rear window glass and outside rear view mirrors
of ice, snow, or fog. (Refer to 8 - ELECTRICAL/
HEATED MIRRORS - DESCRIPTION) for more
information on this feature.
A driver side automatic dimming outside mirror
that dims the mirror to reduce the glare of bright
lights approaching the vehicle from behind, and a
memory system that automatically positions the
power mirrors for two different drivers are optionalfactory-installed equipment on this model. (Refer to 8
- ELECTRICAL/POWER MIRRORS/AUTOMATIC
DAY / NIGHT MIRROR - DESCRIPTION) for more
information. (Refer to 8 - ELECTRICAL/POWER
SEATS - DESCRIPTION) for more information.
This group covers the following components of the
power mirror system:
²Power mirrors
²Power mirror switch.
Certain functions and features of the power mirror
system rely upon resources shared with other elec-
tronic modules in the vehicle over the Programmable
Communications Interface (PCI) data bus network.
The PCI data bus network allows the sharing of sen-
sor information. This helps to reduce wire harness
complexity, internal controller hardware, and compo-
nent sensor current loads. At the same time, this sys-
tem provides increased reliability, enhanced
diagnostics, and allows the addition of many new fea-
ture capabilities. For diagnosis of these electronic
modules or of the PCI data bus network, the use of a
DRB scan tool and the proper Diagnostic Procedures
manual are recommended.
The other electronic modules that may affect power
mirror system operation are as follows:
²Body Control Module (BCM)(Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/BODY CONTROL/CENTRAL TIMER MODUL
- DESCRIPTION) for more information.

POWER WINDOWS
DESCRIPTION
Power operated driver side and passenger side
front and rear door windows are standard factory-in-
stalled equipment on this model. The power window
system allows each of the door windows to be raised
or lowered electrically by operating a switch on the
trim panel for that door. Additionally, the master
switches on the driver side front door trim panel
allow all of the windows to be operated from the
driver seat position. A power window lockout switch
on the driver side front door trim panel will allow the
driver to disable all of the passenger door window
switches.
The power window system functionally operates
when the ignition switch is in the On position. How-
ever, a unique feature of this system will allow the
power windows to be operated for up to forty-five sec-
onds after the ignition switch is turned to the Off
position, or until a front door is opened, whichever
occurs first.
An auto-down feature allows the driver side front
door window to be lowered all the way, even if the
window switch is released. The driver side front door
window switch must be depressed in the down direc-
tion to a second detent to begin an auto-down event.
Depressing the switch again in any direction cancel
the auto-down event and begin movement in the
direction specified.
This group covers the following components of the
power window system:
²Power window switches
²Power window motors.
Certain functions and features of the power win-
dow system rely upon resources shared with other
electronic modules in the vehicle over the Program-mable Communications Interface (PCI) data bus net-
work. The PCI data bus network allows the sharing
of sensor information. This helps to reduce wire har-
ness complexity, internal controller hardware, and
component sensor current loads. At the same time,
this system provides increased reliability, enhanced
diagnostics, and allows the addition of many new fea-
ture capabilities. For diagnosis of these electronic
modules or of the PCI data bus network, the use of a
DRB scan tool and the proper Diagnostic Procedures
manual are recommended.
The other electronic modules that may affect power
window system operation are as follows:
²Body Control Module (BCM)- (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/BODY CONTROL/CENTRAL TIMER MODUL
- DESCRIPTION) for more information.
²Driver Door Module (DDM)-(Refer to 8 -

ULES/DRIVER DOOR MODULE - DESCRIPTION)
for more information.
²Passenger Door Module (PDM)- (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/DRIVER DOOR MODULE - DESCRIPTION)
for more information.
This group covers diagnosis and service of only the
electrical components in the power window system.
For service of mechanical components, such as the
regulator, lift plate, window tracks, or glass refer to
Body. Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, details
of wire harness routing and retention, connector pin-
out information and location views for the various
wire harness connectors, splices and grounds. Follow-
ing are general descriptions of the major components

SPEED CONTROL
DESCRIPTION
The speed control system is electronically con-
trolled and vacuum operated. Electronic control of
the speed control system is integrated into the Pow-
ertrain Control Module (PCM). The controls consist
of two steering wheel mounted switches. The
switches are labeled: ON/OFF, RES/ACCEL, SET,
COAST, and CANCEL.
The system is designed to operate at speeds above
30 mph (50 km/h).
WARNING: THE USE OF SPEED CONTROL IS NOT
RECOMMENDED WHEN DRIVING CONDITIONS DO
NOT PERMIT MAINTAINING A CONSTANT SPEED,
SUCH AS IN HEAVY TRAFFIC OR ON ROADS THAT
ARE WINDING, ICY, SNOW COVERED, OR SLIP-
PERY.
OPERATION
When speed control is selected by depressing the
ON switch, the PCM allows a set speed to be stored
in PCM RAM for speed control. To store a set speed,
depress the SET switch while the vehicle is moving
at a speed between 35 and 85 mph. In order for the
speed control to engage, the brakes cannot be
applied, nor can the gear selector be indicating the
transmission is in Park or Neutral.
The speed control can be disengaged manually by:
²Stepping on the brake pedal
²Depressing the OFF switch
²Depressing the CANCEL switch.
²Depressing the clutch pedal (if equipped).
NOTE: Depressing the OFF switch or turning off the
ignition switch will erase the set speed stored in
the PCM.
For added safety, the speed control system is pro-
grammed to disengage for any of the following condi-
tions:
²An indication of Park or Neutral
²A rapid increase rpm (indicates that the clutch
has been disengaged)
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)
²The speed signal increases at a rate of 10 mph
per second (indicates that the coefficient of friction
between the road surface and tires is extremely low)

VEHICLE THEFT SECURITY
DESCRIPTION
DESCRIPTION - VEHICLE THEFT SECURITY
SYSTEM
The Vehicle Theft Security System (VTSS) is
designed to provide perimeter protection against
unauthorized vehicle use or tampering by monitoring
the vehicle doors, the liftgate, the liftgate flip-up
glass, the ignition system and, only on vehicles built
for sale in certain international markets where it is
required equipment, the hood. If unauthorized vehi-cle use or tampering is detected, the system responds
by pulsing the horn and flashing the exterior lamps.
In many markets the VTSS also includes the Sentry
Key Immobilizer System (SKIS), which provides pas-
sive vehicle protection by preventing the engine from
operating unless a valid electronically encoded key is
detected in the ignition lock cylinder. (Refer to 8 -
ELECTRICAL/VEHICLE THEFT SECURITY -
DESCRIPTION - SENTRY KEY IMMOBILIZER
SYSTEM).
The VTSS includes the following major compo-
nents, which are described in further detail else-
where in this service manual:
