Headlamp High/Low-Beam Changer
53(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 you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will turn
on. They will stay on as long as you hold the levertoward you. The high-beam indicator on the
instrument panel cluster will come on. Release the
lever to return to normal operation.
Windshield Wipers
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the
windshield, gently loosen or thaw them. Damaged
wiper blades may not clear the windshield well,
making it harder to see and drive safely. If the
blades do become damaged, install new blades or
blade inserts. For more information, seeWindshield
Wiper Blade Replacement on page 481
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it
cools down. Clear away snow or ice to prevent an
overload.
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the
band to mist. Hold it there until the wipers start.
Then let go. The wipers will stop after one wipe.
If you want more wipe cycles, hold the band
on mist longer.

The DRL and automatic headlamp system will only
be affected when the light sensor sees a change in
lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 203.
To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic
Headlamp System. SeeDaytime Running Lamps
(DRL) on page 201for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 264.
As with any vehicle, you should turn on the regular
headlamp system when needed.Fog Lamps
-(Fog Lamps):If your vehicle is equipped with
fog lamps, it is located on the instrument panel to
the left of the steering column. The fog lamps
button is located below the dome lamp override
button.
Your ignition must be in RUN for the fog lamps to
illuminate.
To turn the fog lamps on, press the fog lamps
button. A light will come on in the instrument panel
cluster to let you know that the fog lamps are on.
Press the button again to turn the fog lamps off.
The ignition must be in RUN and the parking
lamps must be on for your fog lamps to work.
The fog lamps will go off while you change
to high-beam headlamps.
Some localities have laws that require the
headlamps to be on along with the fog lamps.

Cruise Control Light
This light comes on
whenever you set your
cruise control.
The light will go out when the cruise control is
turned off. SeeCruise Control on page 196
for more information.
Highbeam On Light
This light will come on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on
page 192.
Tow/Haul Mode Light
This light is displayed
when the Tow/Haul
mode has been
activated.
For more information, seeTowing a Trailer on
page 405andTow/Haul Mode on page 145.

No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as
much light to see the same thing at night as a
20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the
day in bright sunshine you are wise to wear
sunglasses. Your eyes will have less trouble
adjusting to night. But if you are driving, do not
wear sunglasses at night. They may cut down on
glare from headlamps, but they also make a
lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several seconds, for your eyes to re-adjust
to the dark. When you are faced with severe glare,
as from a driver who does not lower the high
beams, or a vehicle with misaimed headlamps,
slow down a little. Avoid staring directly into
the approaching headlamps.Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a lm caused
by dust. Dirty glass makes lights dazzle and
ash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less
of a roadway when you are in a turn or curve.
Keep your eyes moving; that way, it is easier to
pick out dimly lighted objects. Just as the
headlamps should be checked regularly for
proper aim, so should your eyes be examined
regularly. Some drivers suffer from night
blindness — the inability to see in dim
light — and are not even aware of it.

What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. SeeRecommended
Fluids and Lubricants on page 564.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been
preset at the factory and should need no further
adjustment.
However, if the vehicle is damaged in an accident,
the aim of the headlamps may be affected and
adjustment may be necessary.
If oncoming vehicles ash their high beams at
you, this may mean the vertical aim of your
headlamps needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
adjusted. It is possible however, to re-aim
the headlamps as described in the following
procedure.The vehicle should be properly prepared as
follows:
The vehicle should be placed so the
headlamps are 25 ft. (7.6 m) from a light
colored wall.
The vehicle must have all four tires on a level
surface which is level all the way to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice, or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
The vehicle should be normally loaded with
a full tank of fuel and one person or
160 lbs (75 kg) sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its proper location in the
vehicle.
Headlamp aiming is done with the vehicle’s
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
