Infants and Young 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.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
Airbags plus lap-shoulder belts offer protection for
adults and older children, but not for young children and
infants. Neither the vehicle’s safety belt system nor
its airbag system is designed for them. Every time
infants and young children ride in vehicles, they should
have the protection provided by appropriate child
restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.

If the vehicle has a trailer towing option with added
wiring for the trailer lamps, a turn signal asher is used.
With this asher installed, the signal indicator ashes
even if a turn signal bulb is burned out. Check the front
and rear turn signal lamps regularly to make sure
they are working.
Turn Signal On Chime
A chime sounds if the turn signal has been on 3/4 of a
mile (1.2 km). Move the turn signal lever to off.
Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam,
push the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
Flash-to-Pass
This feature lets high-beam headlamps be used to
signal to a driver in front of you that you want to pass.
It works even if the headlamps are in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If the headlamps are in the automatic position or on low
beam, the high-beam headlamps turn on. They will stay
on as long as the lever is held toward you. The high-beam
indicator on the instrument panel cluster comes on.
Release the lever to return to normal operation.
Windshield Wipers
8(Mist):Turn the band to mist, for a single wiping
cycle. Hold it there until the wipers start, then release it.
The wipers will stop after one wipe. Hold the band on
mist longer if more wipe cycles are needed.
9(Off):Turns the wipers off.
N(Windshield Wipers):Turn the band to control the
windshield wipers.
6: Turn the band to set the wiper speed for a long or
short delay between wipes. The closer to the top of the
lever, the shorter the delay time.
3-8

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 are only affected when the
light sensor sees a change in lighting lasting longer
than the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on after the transmission
is shifted out of P (Park). Once the vehicle leaves the
garage, it takes about one minute for the automatic
headlamp system to change to DRL if it is light outside.
During that delay, the instrument panel cluster might
not be as bright as usual. Make sure the instrument
panel brightness control is in the full bright position.
If the vehicle is running and the automatic headlamp
system is already on, it can be turned off by turning and
releasing the headlamp control at the off position.
The automatic headlamp system stays off until you turn
and release the headlamp control at the off position
again. SeeHeadlamps on page 3-13.Fog Lamps
The fog lamp button is located on the instrument panel
to the right of the exterior lamps knob. Use the fog
lamps for better vision in foggy or misty conditions.
The ignition must be in ON/RUN for the fog lamps
to work.
#:Press to turn the fog lamps on or off. An indicator
light turns on near the button while the fog lamps
are on. Fog lamps turn off whenever the high-beam
headlamps are on.
Some localities have laws that require the headlamps
to be on along with the fog lamps.

To change the current air delivery mode, select one of
the following:
H(Vent):Air is directed to the instrument panel outlets.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air is directed toward the
windshield and side window outlets. Cooler air is
directed to the upper outlets and warmer air to the oor
outlets.
6(Floor):Air is directed to the oor outlets. Some air
also comes out of the defroster and side window
outlets. The recirculation button cannot be selected in
oor mode.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the oor and windshield
outlets.
0(Front Defrost):Press the front defrost button to
clear the windows of fog or frost more quickly. The
system automatically controls the fan speed if defrost is
selected from AUTO mode. If the outside temperature
is 40°F (4°C) or warmer, the air conditioning compressor
runs automatically to help dehumidify the air and dry
the windshield.
Do not drive the vehicle until all the windows are clear.
#A/C (Air Conditioning):Press to turn the air
conditioning system on or off. When the system is on,
the system automatically begins to cool and dehumidify
the air inside of the vehicle. The air conditioning
symbol appears on the display when the air conditioning
is on and turns off when the air conditioning is off.
If the air conditioning is turned off while in front defrost
or defog mode, the air conditioning symbol turns off,
however, the A/C compressor remains on to help
de-humidify the air inside the vehicle. If one of the other
modes is selected, the compressor will then turn the
A/C off until it is selected again or the AUTO button is
pressed.
To avoid fogging the inside glass on rainy and humid
days at a temperature above freezing, press the
air conditioning button to run the A/C compressor.
Also it is best to avoid the use of the recirculation mode
except when maximum air conditioning performance
is needed or for short times to avoid exterior odors.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal.
