If OFF is selected, the exterior lamps will not turn on.
If a time delay is chosen, the lamps will turn on for
the selected time. The time delay will be cancelled and
the exterior lamps will turn on automatically when
the key is removed from the ignition, or the vehicle is
unlocked using the remote keyless entry transmitter.

HEADLAMPS SUGGESTED
This message comes on when the amount of available
light outside the vehicle is low and the exterior lamps
control has been turned off. This condition happens
when the headlamps are turned off at night or the
Daytime Running Lamps (DRL) are turned off during the
day. This message informs the driver that it has
become dark enough outside to require the headlamps
to be turned on. When the headlamps are turned
on, this message will clear from the screen. SeeExterior
Lamps on page 3-15andDaytime Running Lamps
(DRL) on page 3-16for more information.
This message will display while the ignition is in RUN. A
chime will sound for two seconds when this message
is displayed. Press the set/reset button to acknowledge
this warning message and to clear it from the screen.
This message will continue to display if it has not been
acknowledged when the engine is turned off. It will
also re-display for three seconds if the message has
been acknowledged, but the condition still exists
when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on.
HOT COOLANT
Notice:If the HOT COOLANT warning message
appears on the DIC display, stop the vehicle as soon
as possible. Do not increase the engine speed
above normal idling speed. Severe engine damage
can result from driving a vehicle with an overheated
engine. SeeEngine Overheating on page 5-28for
more information.
This symbol comes on with
the HOT COOLANT
warning message.
This warning message will appear while the engine
coolant temperature is too hot. The hot coolant
temperature warning light will also appear on the
instrument panel cluster. Also, the engine coolant
temperature gage will read in the red or hot area. See
Engine Coolant Temperature Warning Light on
page 3-46andEngine Coolant Temperature Gage on
page 3-46for more information.
To avoid added strain, turn off the air conditioner if it is
on. When the coolant temperature returns to normal,
the air conditioner can be turned back on.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired — by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the glare
from headlamps behind you.
Since you cannot see as well, you may need to
slow down and keep more space between you
and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe place
and rest.
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.
4-19

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting may
occur and damage the vehicle. The repairs would
not be covered by your warranty. Always connect
and remove the jumper cables in the correct
order, making sure that the cables do not touch
each other or other metal.
A. Heavy, Unpainted Metal Engine Part or Remote
Negative (−) Terminal
B. Good Battery or Remote Positive (+) and Remote
Negative (−) Terminals
C. Dead Battery or Remote Positive (+) TerminalTo disconnect the jumper cables from both vehicles, do
the following:
1. Disconnect the black negative (−) cable from the
vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from the
vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the remote positive (+) terminal cover to its
original position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, If the vehicle is damaged in an accident, the
headlamp aim may be affected and adjustment may
be necessary.
If oncoming vehicles ash their high beams at you, this
may also mean the vertical aim needs to be adjusted. Jumper Cable Removal
5-50

It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be re-aimed.
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 or other at
surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other at surface.
The vehicle should be placed so it is perpendicular
to the wall or other at surface.
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 done.
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.Headlamp aiming is done with the low-beam headlamps.
The high-beam headlamps will be correctly aimed if
the low-beam headlamps are aimed properly.
To adjust the vertical aim, do the following:
1. Find the aim dot on the lens of the low-beam lamp.
2. Measure the distance from the ground to the aim
dot on the lamp. Record the distance.
3. At the wall or other at surface, measure from the
ground upward the recorded distance from Step 2
and draw or tape a horizontal line the width of
the vehicle.
