disarming the system. When the
alarm is activated, the turn signals
flash and the horn sounds for about
30 seconds. The alarm system will
then re-arm to monitor for the next
unauthorized event.
The vehicle can be started with the
correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by
accident:
.Lock the vehicle with the door
key after the doors are closed.
. Unlock the door with the RKE
transmitter. Unlocking a door any
other way sets off the alarm if
the system has been armed.
Press
Kor place the key in the
ignition and turn it to START to turn
off the alarm.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower the driver side window, and
open the driver door.
2. Press
Q. 3. Get out of the vehicle, close
the door, and wait for the
security light to go out.
4. 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 0261.
If the alarm does not sound or the
headlamps do not flash, see your
dealer for service.
Immobilizer
See Radio Frequency
Statement 0340.
Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key III+ is a passive
theft-deterrent system. The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned to
ON/RUN, ACC/ACCESSORY,
or START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses an incorrect key, the vehicle
does not start. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and the
security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with the theft-deterrent system. Turn
the ignition off and try again.

234 Driving and Operating
When using a weight-distributing
hitch, the hitch must be adjusted so
that the distance (2) remains the
same both before and after coupling
the trailer to the tow vehicle.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Always leave just enough slack so
the rig can turn. Never allow safety
chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 450 kg (1,000 lb) needs to have
its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted, and
maintained properly.Because the vehicle has antilock
brakes, do not try to tap into the
vehicle's hydraulic brake system.
If you do, both brake systems will
not work well, or at all.
Trailer Wiring Harness
Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle's frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer.
Use only a round, seven-wire
connector with flat blade terminals
meeting SAE J2863 specifications
for proper electrical connectivity.
The seven-wire harness contains
the following trailer circuits:
.
Yellow: Left Stop/Turn Signal
. Dark Green: Right Stop/Turn
Signal
. Brown: Taillamps
. Black: Ground .
Light Green: Back-up Lamps
. Red/Black: Battery Feed
. Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.
They should be connected by your
dealer or a qualified service center.
If the back-up lamp circuit is not
functional, contact your dealer.
To help charge a remote
(non-vehicle) battery, press the Tow/
Haul Mode button at the end of the
shift lever. If the trailer is too light for
Tow/Haul Mode, turn on the
headlamps to help charge the
battery.
Electric Trailer Brake Control
Wiring Provisions
These wiring provisions for an
electric trailer brake controller are
included with the vehicle as part of
the trailer wiring package. The
instrument panel contains blunt cut
wires above the parking brake
