4. Buckle, position and release the safety belt as
described in ªRear Seat Passenger Positions
(Extended Cab and Crew Cab)º earlier in this
section. Make sure that the shoulder belt crosses
the shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out of the
guides. Slide the guide onto the storage clip.
Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes the
need, for everyone, to use safety restraints. In fact, the
law in every state in the United States and in every
Canadian province says children up to some age must be
restrained while in a vehicle.
Infants and Young Children
Every time infants and young children ride in vehicles,
they should have the protection provided by the
appropriate restraint. Young children should not use the
vehicle's safety belts, unless there is no other choice.

Keyless Entry System (If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 100 feet (30 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device 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 received, including
interference that may cause undesired operation of
the device.Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement or
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-14
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.
To replace the battery in the keyless entry transmitter, do
the following:
1. Insert a dime, or similar object, in the slot between
the covers of the transmitter housing near the key
ring hole. Remove the bottom by twisting the dime.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.

When starting your engine in very cold weather (below
0
F or
-18
C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of the key.
2. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the vehicle
starts briefly but then stops again, do the same
thing, but this time keep the pedal down for five or
six seconds. This clears the extra gasoline from
the engine.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F
(
-18
C) or colder, the
engine coolant heater can
help. You'll get easier
starting and better fuel
economy during engine
warm
-up. Usually, the
coolant heater should be
plugged in a minimum of
four hours prior to starting
your vehicle.
At temperatures above 32
F (0
C), use of the coolant
heater is not required.

Manual Selectable Ride (If Equipped)
The main function of this system is to provide superior
ride comfort while trailering or fully loaded, as well as
for unloaded driving. This system also helps to provide:

Improved trailering stability

Improved handling response when trailering or
fully loaded
This button is located on
the center of the instrument
panel near the radio. Press it
to activate the selectable
ride setting as desired.
An indicator light near
the button will illuminate
whenever the system
is active.
It is recommended to use this system as follows:

For optimum ride comfort in an unloaded vehicle the
button should be out and the indicator light will not
be illuminated. This switch position indicates
NORMAL levels of ride control or damping.
For optimum ride comfort when trailering, fully
loaded, driving off
-road, or when personal
preferences demand more control the button should
be pressed in with the indicator light illuminated.
This switch position indicates FIRM levels of ride
control or damping.
The following guide can also be used to help determine
the best setting.
NORMAL: The indicator light will be off when the
system is in this setting. Use for normal city and
highway driving. Provides a smooth, soft ride when the
vehicle is unloaded.
FIRM (Unloaded): Press the switch to activate this
setting, the indicator light will illuminate. Use this
setting when road conditions or personal preference
demand more control. Provides more ªfeelº or response
to the road conditions.
FIRM (Loaded): Press the switch to activate this
setting, the indicator light will illuminate. Use this
setting to minimize trailer inputs to the vehicle or when
the vehicle is fully loaded. This setting is also
appropriate for off
-road driving.
You can select a setting at any time based on road and
trailering conditions to provide the best ride and
handling. Select a new setting whenever driving
conditions change.

Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor located on
the top of the instrument panel in the defroster grille. Be
sure it is not covered, or the system will be on whenever
the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting longer
than the delay.To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later in
this section for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need them.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
chime, turn the thumbwheel all the way down. In the
automatic mode, the headlamps turn off once the
ignition key is in OFF.

Electrochromic Inside Rearview Mirror
with Compass, Temperature Display and
OnStar Controls (If Equipped)
When on, an electrochromic mirror automatically dims
to the proper level to minimize glare from lights behind
you after dark.
The mirror also includes a duel display in the upper
right corner of the mirror face. The compass reading and
the outside temperature will both appear in the display at
the same time.Temperature and Compass Display
Press the on/off button, located to the far left, briefly to
turn the comp/temp display on or off.
If the display reads CAL, you will need to calibrate
the compass. For more information on calibration,
see below.
To adjust between Fahrenheit and Celsius do
the following:
1. Press and hold the on/off button for four seconds
until either a flashing
F, or
C appears.
2. Press the button again to change the display to the
desired unit of measurement. After approximately
four seconds of inactivity, the new unit will be
locked in and the compass/temperature display
will return.
