Power Door Locks
If your vehicle has power
door locks, press the
power door lock switch
located on the door panel
to lock or unlock all the
doors at once.
The power door lock switch will lock or unlock the rear
hatch and Dutch doors. See “Hatch Release” in
Rear Doors on page 2-12.
When a door is locked, the inside door handle will not
open the door. This will help stop a door from being
accidentally opened.
If the sliding door is open and you press the power door
lock switch, the sliding door will not lock immediately.
After you close the door, the system comes on and locks
the sliding door in about ve seconds.
When the key is in the ignition and the power door lock
switch is pressed with a door open, all doors are
locked while the driver’s side door remains unlocked.
Programmable Automatic
Door Locks
Your vehicle is equipped with an auto lock/unlock feature
which enables you to program your power door locks.
Your vehicle left the factory programmed to have all the
doors lock automatically when the shift lever is moved out
of PARK (P). All of the doors will unlock when the shift
lever is moved back into PARK (P). The following
instructions detail how to program your door locks.
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then, pull back on the
turn signal/multifunction lever all the way toward you
and hold it while you perform the next step.
2. Turn your key to RUN and OFF twice. Then, with
the key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock
switch lock and unlock.
You are now ready to program the automatic door locks.
Select one of the following four programming options and
follow the instructions. You will have thirty seconds to
begin programming. If you exceed the thirty second limit,
the locks will automatically lock and unlock to indicate
that you have left the program mode. If this occurs, repeat
the procedure beginning with Step 1. You can exit the
program mode any time by turning the ignition to RUN.

If you manually select SECOND (2), the transmission
will drive in second gear. You may use this feature
for reducing torque to the rear wheels when you
are trying to start your vehicle from a stop on slippery
road surfaces.
FIRST (1):This position gives you even more
power (but lower fuel economy) than SECOND (2).
You can use it on very steep hills, or in deep snow or
mud. If the shift selector lever is put in FIRST (1),
the transmission won’t shift into rst gear until the
vehicle is going slow enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. If you
are stuck, do not spin the tires. When stopping
on a hill, use the brakes to hold the vehicle in place.Tow/Haul Mode Button
Your vehicle is equipped with a tow/haul button.
The button is located on the end of the column shift
lever. You can use this feature to assist when towing
or hauling a heavy load.
To select the tow/haul mode, press in the button.
The TOW/HAUL light on the instrument panel cluster
will come on. To go back to normal operation, press
the button again. The indicator light on the instrument
panel cluster will go out. SeeTow/Haul Mode Light
on page 3-34for more information.

If your vehicle is equipped with the HomeLink®
Transmitter, it complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions: (1) this device may not cause
interference, and (2) this device must accept any
interference, including interference that may
cause undesired operation of the device.
Changes and modications to this system by
other than an authorized service facility could void
authorization to use this equipment.Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of the
steps involved, it may be helpful to have another person
available to assist you in programming the transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle, the
programmed HomeLink
®buttons should be erased for
security purposes. Refer to “Erasing HomeLink®Buttons”
or, for assistance, contact HomeLink®on the internet at:
www.homelink.com or by calling 1-800-355-3515.
2-33

8. Return to the vehicle. Firmly press and hold the
programmed HomeLink®button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
®should now activate your rolling-code
equipped device.
To program the remaining two HomeLink
®buttons,
begin with Step 2 of “Programming HomeLink®.”
Do not repeat Step 1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured
to “time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®” procedures (regardless of
where you live), replace Step 3 under “Programming
HomeLink
®” with the following:Continue to press and hold the HomeLink
®button
while you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal
has been successfully accepted by HomeLink
®.
The indicator light will ash slowly at rst and then
rapidly. Proceed with Step 4 under “Programming
HomeLink
®” to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button
for at least half of a second. The indicator light will
come on while the signal is being transmitted.
Erasing HomeLink®Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
®is now in the train (learning) mode and
can be programmed at any time beginning with Step 2
under “Programming HomeLink
®.”
Individual buttons can not be erased, but they can
be reprogrammed. See “Reprogramming a Single
HomeLink
®Button” next.

COMP/TEMP (Compass/Temperature):This display
provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle
is facing.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the
outside temperature is 37°F (3°C) or lower, the display
will toggle between the word ICE and the current
temperature every eight seconds. This is a warning
to the driver that road conditions may be icy, and that
appropriate precautions should be taken.
The compass is self-calibrating, so it does not need
to be manually set. However, if C (Calibration) is
displayed, the compass will need to be calibrated.
You may also place the compass in a noncalibrated
mode by pressing and holding the US/MET and
MODE buttons simultaneously while in the COMP/TEMP
mode. After about 10 seconds, the compass will
display C and you can release the buttons. Drive the
vehicle in a complete 360° circle three times at a
speed of less than 5 mph (8 km/h), and the compass
will function normally. Once the calibration is complete,
the display will return to a compass reading.Variance is the difference between magnetic north
and geographic north. In some areas, the difference
between the two can be great enough to cause
false compass readings. If this happens, follow these
instructions to set the variance for your particular
location:
1. Find your location on the zone map. Record your
zone number.
2. Press and hold both the US/MET and the MODE
buttons while in the COMP/TEMP mode.
2-41

3. After ve seconds, the compass will acknowledge
the variation mode by displaying the current zone
number. When it does, release both buttons.
4. Press US/MET until your zone number appears
on the display.
5. Press MODE to enter your zone number.
Your variance is now set and the display will
return to the COMP/TEMP mode.
TRIP:Once in the TRIP mode, pressing the MODE
button will take you through the following TRIP functions:
AVG ECON (Average Economy):The average
fuel economy since the last reset is displayed.
INST ECON (Instantaneous Economy):
Instantaneous fuel economy for the last second
of driving is displayed.
RANGE:The display indicates the estimated
distance that can be travelled with the remaining
fuel in the tank, based on the fuel economy for
the last few hours of driving.
FUEL USED:The fuel used since the last reset
is displayed.
AVG SPEED (Average Speed):The average
speed since the last reset is displayed.To reset the trip computer, press the MODE and
US/MET buttons simultaneously for at least two
seconds. All functions will be displayed briey once the
system is reset. Reset can only be performed in the
AVG ECON, FUEL USED and AVG SPEED modes.
All three modes are reset simultaneously.
Sunglasses Storage Compartment
The overhead console has a sunglasses
storage compartment.

Then, during the rst 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
See also “Driving on Grades” later in this section.
Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Tow/Haul Mode
Tow/haul is designed to assist while your vehicle is
pulling a large or heavy load or trailer. Tow/haul is
most useful while pulling such a load in rolling terrain,
in stop-and-go traffic, or when you need improved
low-speed control, such as when parking. The purpose
of the tow/haul mode is to:
Reduce the frequency and improve the predictability
of transmission shifts,
provide the same solid shift feel when pulling a
heavy load as when the vehicle is unloaded, and
improve control of vehicle speed while requiring
less throttle pedal activity.Press the button on the end of the shift lever to turn
tow/haul mode on and off. While activated, the indicator
light on the instrument panel will be on. Tow/haul
mode will turn off automatically when the ignition is
turned off. SeeTow/Haul Mode Light on page 3-34.
Tow/haul is most effective when the vehicle and trailer
combined weight is at least 75% of the vehicle’s
Gross Combined Weight Rating (GCWR). See “Weight
of the Trailer” later in this section.
Driving with tow/haul activated without a heavy load
will cause reduced fuel economy and unpleasant engine
and transmission driving characteristics, but will not
cause damage.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig.
For example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to
pull a trailer are all important. And, it can also
depend on any special equipment that you have
on your vehicle.
