Exterior Lamp Controls
The exterior lamps control is located
on the instrument panel, on the
outboard side of the steering wheel.
It controls the following systems:
•Headlamps
•Sidemarker Lamps
•Parking Lamps
•Taillamps
•License Plate Lamps
•Instrument Panel Lights
•Fog Lamps
•Daytime Running Lamps (DRL)
The exterior lamps control has

Running Lamps (DRL) on page 5-3.
Lighting 5-1

Flash-to-Pass
The flash-to-pass feature works with
the low-beams or daytime running
lamps (DRL) on or off.
To flash the high beams, pull the turn
signal/lane change lever all the way
towards you. Then release it.
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 first 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 will make the
low-beam headlamps come on at a
reduced brightness or for vehicles
with High Intensity Discharge(HID) headlamps, the dedicated
DRL lights will come on when
the following conditions are met:
•The ignition is in the ON/RUN
position.
•The exterior lamps control is
in AUTO, or has been briefly
turned to OFF to turn the
automatic light control on again.
•The engine is running.
When the DRL are on, the
headlamps, taillamps, sidemarker,
instrument panel and other
lamps will not be on.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings.
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.To turn the DRL lamps off or on
again, turn the exterior lamps control
to the off position and then release.
For vehicles first sold in Canada, the
DRL lamps cannot be turned off.
The regular headlamp system should
be turned on when needed.
Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO, the
automatic headlamp system will turn
on the headlamps at the normal
brightness along with other lamps
such as the taillamps, sidemarker,
parking lamps, license plate lamps,
and the instrument panel lights.
The radio lights will also be dim.
To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release. For vehicles first sold in
Canada, the transmission must be in
the P (Park) position, before the
automatic headlamp system can be
turned off.
Lighting 5-3

The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover this sensor
or the system will come on
whenever the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp systems so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor sees
a change in lighting lasting longer
than the delay.If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there will
be a slight delay before the
automatic headlamp system
changes to the DRL. During that
delay, the instrument panel cluster
may not be as bright as usual.
Make sure the instrument panel
brightness control is in the full bright
position. SeeInstrument Panel
Illumination Control on page 5-5.
Hazard Warning Flashers
|
Hazard Warning Flasher:
Press this button located on the
instrument panel near the audio
system, to make the front and rear
turn signal lamps flash on and
off. This warns others that you are
having trouble. Press again to
turn the flashers off.
Turn and Lane-Change
Signals
An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Move the lever all the way up or
down to signal a turn.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the
lane change is completed. If the
lever is briefly pressed and released,
the turn signal flashes three times.
5-4 Lighting

The lever returns to its starting
position whenever it is released.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
SeeElectrical System Overload
on page 9-41.
Front Fog Lamps
For vehicles with front fog lamps,
the button is located on the exterior
lamp control, on the outboard
side of the steering wheel.
The ignition must be turned to
ON/RUN to turn on the fog lamps.
#:Press to turn the fog lamps
on or off. An indicator light on
the instrument panel cluster comes
on when the fog lamps are on.
The fog lamps come on together
with the parking and sidemarker
lamps.
If the high-beam headlamps are
turned on, the fog lamps will turn off.
If the high-beam headlamps are
turned off, the fog lamps will
turn back on again. For vehicles
with High Intensity Discharge (HID)
headlamps, the Daytime Running
Lamps (DRL) replace the fog lamps.
Some localities have laws that
require the headlamps to be
on along with the fog lamps.Interior Lighting

6-12 Infotainment System

Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the item
from the accessory power outlet.
FM
FM signals only reach about
16 to 65 km (10 to 40 miles).
Although the radio has a built-in
electronic circuit that automatically
works to reduce interference,
some static can occur, especially
around tall buildings or hills, causing
the sound to fade in and out.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
XM™ Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from
coast-to-coast in the 48 contiguous
United States, and in Canada.
Just as with FM, tall buildings or hills
can interfere with satellite radio
signals, causing the sound to fade
in and out. In addition, traveling
or standing under heavy foliage,
bridges, garages, or tunnels may
cause loss of the XM signal for
a period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle’s radio.
This interference may occur when
making or receiving phone calls,
charging the phone’s battery,
or simply having the phone on.
This interference can cause
an increased level of static while
listening to the radio. If static
is received while listening to the
radio, unplug the cellular phone and
turn it off.
Backglass Antenna
The AM-FM antenna is integrated
with the rear window defogger,
located in the rear window. Make
sure that the inside surface of
the rear window is not scratched
and that the lines on the glass are
not damaged. If the inside surface
is damaged, it could interfere
with radio reception. For proper
radio reception, the antenna
connector needs to be properly
attached to the post on the glass.
