Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for about
six seconds. For this feature to work, automatic lighting
must be enabled. SeeHeadlamps on page 3-32for
additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also
turn off if the windshield wiper control is turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-70for additional
information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.The DRL system comes on when the following
conditions are met:
It is still daylight and the ignition is on.
The automatic lights are enabled.
The transmission is not in P (Park).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. The 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 the vehicle is started in a dark garage, the
automatic headlamp system comes on immediately.
Once the vehicle leaves 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,
the instrument panel cluster may not be as bright as
usual. Make sure the instrument panel brightness lever
is in the full bright position. SeeInstrument Panel
Brightness on page 3-40.
3-36

To operate the 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. SeeDIC Warnings and Messages
on page 3-79.
The regular headlamp system should be turned on
when needed.
Light Sensor
The light sensor for the DRL is located on top of the
instrument panel. If the sensor is covered, it will prevent it
from sensing light, and the exterior lamps may come on
when they are not needed.
3-37

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.
For vehicles with the Head-Up Display (HUD), some of
the driver information that appears on the instrument
panel cluster is projected onto an image on the
windshield.
The information can be displayed in English or metric
units. To change from English to metric units, see
DIC Operation and Displays on page 3-72.
The HUD consists of the following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Driver Shift Control Transmission Feature, see
Automatic Transmission Operation on page 2-30
Check Gages Icon
Adaptive Cruise Control Features and Indicators
(If Equipped), seeAdaptive Cruise Control on
page 3-20
Forward Collision Alert Features and Indicators
(If Equipped), seeForward Collision Alert (FCA)
System on page 3-9
Radio Features
Always scan the instrument panel displays, controls and
driving environment just as you would in a vehicle without
HUD, so important warning lights are not missed. Under
important warning conditions, the CHECK GAGES
message will display in the HUD. View the Driver
Information Center (DIC) for more information.United States version
shown, Canada similar

4. Lift the inboard edge of the deector to release the
retention tab.
5. Lift and slide the water deector toward the inboard
side and remove it.
6. The top edge of the lter should be visible. Reach
in and lift the lter out, pulling upward and toward
the front of the vehicle.
7. Insert the new air lter by sliding it back into place.
Make sure the arrow on the lter is pointing toward
the passenger compartment.
Reverse steps 1 through 3 to reinstall the water
deector, lter cover and the hood seal.Warning Lights, Gages, and
Indicators
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
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.

DIC Warnings and Messages
Messages 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.
The text messages are the same for both the base
audio and Navigation systems unless otherwise
indicated.
Some messages may not require immediate action, but
you can press the reset button to acknowledge that
you received the messages and to clear them from
the display.
Some messages cannot be cleared from the DIC display
because they are more urgent. These messages require
action before they can be cleared. 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.
ADVISORY: XXX MPH (KM/H)
This message displays when the Speed Alert has been
turned on through the DIC Information Menu and the
vehicle is at or above the advised speed. SeeDIC
Operation and Displays on page 3-72for more
information.
AUTOMATIC LIGHTS OFF
This message displays when the automatic headlamps
are turned off. SeeHeadlamps on page 3-32for
more information.
AUTOMATIC LIGHTS ON
This message displays when the automatic headlamps
are turned on. SeeHeadlamps on page 3-32for
more information.
