Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system’s automatic headlamp control will
make the low-beam headlamps come on at a reduced
brightness when the following conditions are met:
The ignition is in the ON/RUN position.
The exterior lamps control is in AUTO.
The engine is running.
When the DRL are on, only the low-beam headlamps, at
a reduced level of brightness, will be on. The headlamps,
taillamps, sidemarker, and other lamps will not be on.
The instrument panel and cluster will also not be lit.When it is dark enough outside, the low-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.
When it is bright enough outside, the headlamps will go
off and the DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when it is needed.
Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the control 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 the exterior lamps button 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 Brightness
D(Instrument Panel Brightness):The knob with
this symbol on it is located next to the exterior lamps
control. Push the knob in all the way until it extends out
and then turn the knob clockwise to brighten or
counterclockwise to dim the lights. Push the knob back
in when nished.
Courtesy Lamps
When 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 Lamp
The dome lamp will come on when you open a door.
You can also turn this lamp on by turning the instrument
panel brightness control clockwise.
Entry Lighting
Your vehicle may have courtesy lamps that will come on
and stay on for a set time whenever the unlock symbol
is pressed on the Remote Keyless Entry (RKE)
Transmitter, if the vehicle has one.
If a door is opened, the lamps stay on while it is open
and then turn off automatically about 25 seconds
after the door is closed. If the unlock symbol is pressed
and you do not open a door, the lamps turn off after
about 20 seconds.
Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at
the end of the delay time. Instead, they slowly dim after
the delay time until they go out. The delay time is
canceled if you turn the ignition key to ON/RUN or
press the power door lock switch. The lamps will dim
right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps will not come on unless
a door is opened.

Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will continue
to work until one of the following occurs:
The ignition is in ON/RUN.
The doors are locked.
An illumination period of 25 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.
Delayed Exit Lighting
This 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 will
activate and remain 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 Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the dimming of
the instrument panel displays during the daylight
while the headlamps are on so that you will still be able
to see the displays.

Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
Mirror Reading Lamps
Your vehicle has reading lamps on the rearview mirror.
Push the button to turn the reading lamps on and off.
Electric Power Management
The 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 put the charge back in. 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.
A high electrical load occurs when several of the
following loads are on: 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 or
Service Battery Charging System. 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 3-52.

Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and a cigarette
lighter. The ashtray and cigarette lighter may be
located in the console, if your vehicle has one,
otherwise, they may be located in the center armrest
of the front seat.
Notice:If you put papers, pins, or other ammable
items in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items in
the ashtray.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
To use the lighter, just push it in all the way and let go.
When it’s ready, it will pop back out by itself.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the engine
just to let you know they’re working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section
that tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly – and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-44.

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s belt
is already buckled, neither the chime nor the light will
come on.
Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
will sound for several seconds to remind the front
passenger to buckle their safety belt. This would only
occur if the passenger airbag is enabled. SeePassenger
Sensing System on page 1-62for more information.
The passenger safety belt light will also come on and
stay on for several seconds, then it will ash for
several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
