Daytime Running Lamps (DRL)
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.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
It is still daylight and the ignition is on,
the automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only your front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. Your instrument panel will not be lit.
When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it is bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. 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 about one minute for the automatic headlamp
system to change to DRL if it is light outside.During that delay, your instrument panel cluster may
not be as bright as usual. Make sure your instrument
panel brightness lever is in the full bright position.
SeeInstrument Panel Brightness on page 3-41.
To operate your vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking lamp
position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to off and
back to AUTO.
An AUTOMATIC LIGHTS OFF message will appear on
the DIC, showing that automatic lighting has been
disabled.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®you will see the following
happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the off position.
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 light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in full bright position. SeeInstrument Panel
Brightness on page 3-41for more information.
You can idle the vehicle with the lamps off, even when
it is dark outside. First set the parking brake while
the ignition is in OFF/ACC. Then start the vehicle. The
lamps will stay off until you release the parking
brake.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
a delay time that you select has elapsed.

If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass and the fan may cut back to a lower
speed. For more battery saving information, see “Battery
Saver Active Message” underDIC Warnings and
Messages on page 3-78.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes if
a new car has 15 miles (24 km) or less). Power will
be restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
The Head-Up Display (HUD) allows you to see some of
the driver information that appears on your instrument
panel cluster on the windshield.
The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. To change from English
to metric units, seeDIC Controls and Displays on
page 3-74.

AUTO will appear on the display next to the fan, mode
indicators, and recirculation indicator if your vehicle
is equipped with the optional air quality sensor.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will try to
continuously heat the vehicle and will not adjust the
system down as the vehicle warms up.
In cold weather, the system may start at reduced
fan speeds to avoid blowing cold air into your
vehicle until warmer air is available. The system will
start out blowing air at the oor but may change
modes, automatically, as the vehicle warms
up to maintain the chosen temperature setting. The
length of time needed for warm up will depend
on the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-74.The air-conditioning system removes moisture from the
air, so you may notice water dripping underneath
your vehicle while idling or after turning off the engine.
This is normal.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation and
allows the operator to manually select the air delivery
location. Press AUTO to return to automatic operation.
The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet Adjustment
on page 3-56to change this airow from the outboard
outlets.
To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets. In
automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, and a little air directed to the windshield and
side windows.

Under some conditions, the air quality sensor system
will not operate. In cold weather, the system may not be
active (even if the AUTO indication is displayed)
because of concerns of fogging your windows, which
may occur by activating recirculation mode. Also, the air
quality sensor system will not remain in recirculation
mode for extended periods of time that could cause
stuffy or very dry conditions in the vehicle. Following a
poorly running vehicle for an extended period of
time may not keep recirculation active indenitely.
The air quality sensor will not activate due to organic
odors, like skunk, and may not activate on many
chemical-related odors. If you wish to limit these types
of odors, you may choose to manually select
recirculation. Your vehicle may also be equipped with
a charcoal lter that can limit many odors from
being pulled into your vehicle. This lter, like your
engines air cleaner lter, will need to be changed
periodically. SeeScheduled Maintenance on page 6-4.
The air quality sensor system does not protect
against carbon monoxide (CO), which you cannot see
or smell. SeeEngine Exhaust on page 2-33.
