When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the Remote Keyless Entry
(RKE) or Keyless Access System transmitter, if
the vehicle has one, the power door lock switch,
or the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If the power door lock switch is pressed when the key
is in the ignition and a door is open, all the doors will lock
and only the driver’s door will unlock. If you close the
doors, they can be locked by using the Remote Keyless
Entry (RKE) transmitter. Be sure to remove the key from
the ignition when locking your vehicle.
This feature can be overridden by pressing the lock
button on the RKE transmitter or by pressing the power
lock switch a second time.
On vehicles with a Keyless Access System, the system
can be programmed to alert you when all the doors
are closed and a transmitter has been left inside of the
vehicle. SeeDIC Vehicle Customization on page 3-69
for more information.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk
lid open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.

Ashtray(s) and Cigarette Lighter
Your vehicle may have two removable ashtrays and
cigarette lighters. One ashtray can be placed into
the instrument panel storage compartment and the other
into the center console rear compartment. To use the
lighter, push it in all the way and let go. When it is ready,
it will pop back out by itself.
To empty the ashtrays, grip the edges of the bin and
pull it straight out of the housing. To reinstall, push the
tray back into place.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items in
the ashtray.

Climate Controls
Dual Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
O(Power):Press this button to turn the climate control
system on or off. When the climate control system is
turned off the air inlet defaults to outside air.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system automatically
controls the inside temperature, the air delivery mode,
the air conditioning compressor, and the fan speed.When the indicator light is on, the system is in full
automatic operation. If the air delivery mode or fan
setting is manually adjusted, the auto indicator turns off
and displays will show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 60°F (15.5°C) and 90°F (32.2°C).
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
If the system is set at the warmest temperature
setting, it remains in manual mode at that
temperature and it will not go into automatic mode.
In cold weather, the system starts at reduced fan
speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system begins
blowing air at the oor but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of
time the system needs to warm up depends on the
outside temperature and the length of time that
has elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-69.

Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they are all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down to a lower gear and
reduce your speed to around 45 mph (70 km/h) to
reduce the possibility of engine and transmission
overheating.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and then shift to PARK (P).
5. Release the regular brakes.
4-36

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission uid (don’t overll),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you nd them quickly. If you’re trailering, it’s a
good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-31.
