Fog Lamps#
(Fog Lamps):For vehicles with fog lamps,
the button is located on the exterior lamps control.
The exterior lamps control is located on the instrument
panel to the left of the steering column.
The ignition must be in the ON/RUN position for the fog
lamps to come on.
Press
#
to turn the fog lamps on or off. A light will
come on in the instrument panel cluster.
When the headlamps are changed to high-beam, the
fog lamps also go off.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Instrument Panel BrightnessD
(Instrument Panel Brightness):The knob with this
symbol on it is located next to the exterior lamps control
to the left of the steering wheel. Push the knob in all the
way until it extends out and then turn the knob clockwise
or counterclockwise to brighten or dim the lights. Push
the knob back in when finished.
Courtesy LampsWhen a door is opened, the courtesy lamps
automatically come on. They make it easy for you to
enter and leave your vehicle. You can also manually
turn these lamps on by fully turning the instrument
panel brightness control clockwise.
The reading lamps, located on the rearview mirror,
can be turned on or off independent of the automatic
courtesy lamps, when the doors are closed.Dome LampThe center mounted dome lamp overhead comes on
when a door is opened. This lamp can also be turned
on by turning the instrument panel brightness control
clockwise.

Delayed Exit LightingThis feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the key is removed, interior illumination activates
and remains on until one of the following occurs:•
The ignition is in ON/RUN.
•
The power door locks are activated.
•
An illumination period of 20 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade DimmingParade mode automatically prohibits the dimming of
the instrument panel displays during the daylight while
the headlamps are on so that the displays are still
able to be seen.Reading LampsThe vehicle has reading lamps that also act as the
dome lamp. Press the button near each lamp to turn
them on and off.
Map LampsThe vehicle has map lamps on the rearview mirror.
Press the button near each lamp on the mirror to turn
the map lamps on and off.Electric Power ManagementThe vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or down.
This is normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
4-13

A high electrical load occurs when several of the
following are on, such as: headlamps, high beams,
fog lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the battery.
It does this by balancing the generator’s output and the
vehicle’s electrical needs. It can increase engine idle
speed to generate more power, whenever needed.
It can temporarily reduce the power demands of some
accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 4-44.
Battery Run-Down ProtectionThis feature helps prevent the battery from being drained,
if the interior courtesy lamps, reading/map lamps, visor
vanity lamps or trunk lamp are accidentally left on. If any
of these lamps are left on, they automatically turn off after
10 minutes, if the ignition is off. The lamps will not come
back on again until one of the following occurs:•
The ignition is turned on.
•
The exterior lamps control is turned off, then on
again.
The headlamps will timeout after 10 minutes, if they are
manually turned on with the ignition on or off.
4-14

Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 4-5
for more information.
Fuel GageWhen the ignition is on, the fuel gage indicates about
how much fuel is left in the fuel tank.An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
Here are four things that some owners ask about.
None of these show a problem with the fuel gage:
•
At the gas station, the gas pump shuts off before the
gage reads full.
•
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the fuel tank’s capacity
to fill the tank.
•
The gage moves a little when while turning a corner
or speeding up.
•
The gage does not go back to empty when the
ignition is turned off.

DIC Warnings and MessagesMessages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that some
action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another. Some messages may not require immediate
action, but you can press the set/reset button to
acknowledge that you received the message and clear
it from the DIC display. Pressing any of the DIC buttons
also acknowledges and clears any messages. Some
messages cannot be cleared from the DIC display
because they are more urgent. These messages require
action before they can be cleared. You should take any
messages that appear on the display seriously and
remember that clearing the messages will only make
the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.AUTOMATIC LIGHT CONTROL OFFThis message displays when the automatic headlamps
are turned off. SeeExterior Lamps on page 4-9for
more information.AUTOMATIC LIGHT CONTROL ONThis message displays when the automatic headlamps
are turned on. SeeExterior Lamps on page 4-9for
more information.
BATTERY SAVER ACTIVEThis message displays when the system detects that
the battery voltage is dropping beyond a reasonable
level. The battery saver system starts reducing certain
features of the vehicle that you may be able to notice.
At the point that the features are disabled, this message
is displayed. It means that the vehicle is trying to
save the charge in the battery.
Turn off all unnecessary accessories to allow the battery
to recharge.
The normal battery voltage range is 11.5 to 15.5 volts.CHANGE ENGINE OIL SOONThis message displays when service is required for the
vehicle. See your dealer/retailer. SeeEngine Oil on
page 6-15andScheduled Maintenance on page 7-3
for more information.

Driving at NightNight driving is more dangerous than day driving because
some drivers are likely to be impaired — by alcohol or
drugs, with night vision problems, or by fatigue.
Night driving tips include:•
Drive defensively.
•
Do not drink and drive.
•
Reduce headlamp glare by adjusting the inside
rearview mirror.
•
Slow down and keep more space between you and
other vehicles because headlamps can only light up
so much road ahead.
•
Watch for animals.
•
When tired, pull off the road.
•
Do not wear sunglasses.
•
Avoid staring directly into approaching headlamps.
•
Keep the windshield and all glass on your vehicle
clean — inside and out.
•
Keep your eyes moving, especially during turns or
curves.
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 might need at least twice as much
light to see the same thing at night as a 20-year-old.
5-13

Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about
to keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery charged to restart
the vehicle and to signal for help with the headlamps.
Do this as little as possible to save fuel.If Your Vehicle is Stuck in Sand,
Mud, Ice, or SnowSlowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5-20.
If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle’s traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{
WARNING:
If the vehicle’s tires spin at high speed, they can
explode, and you or others could be injured. The
vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
seeTire Chains on page 6-73.
