Headlamps on Reminder
If you open the driver’s door while leaving the
headlamps or parking lamps on and the key is in OFF,
you will hear a warning chime.
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.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
®, so be sure it is not covered. The DRL
system will make your low-beam headlamps come on
at a reduced brightness. In order for the DRL system to
be activated, the following conditions must be met:
The ignition is on.
The exterior lamp control is off.
The transaxle is not in PARK (P).When the DRL are on, only your low-beam headlamps
will be on at reduced intensity. The taillamps,
sidemarker and other lamps will not be on. Your
instrument panel will not be lit either.
When it is dark enough outside, your regular intensity
headlamps will come on at full brightness and the
DRL lighting will turn off. The parking lamps that
normally come on with your headlamps will also come
on. When it is bright enough outside, the regular
intensity headlamps and parking lamps will turn back
off, and the reduced brightness DRL lighting will
turn back on.
To idle your vehicle during the day with the DRL off,
shift the transaxle into PARK (P). The DRL will stay off
until you shift out of PARK (P).
At night, you can turn off all exterior lamps when you
are in PARK (P) by turning the Twilight Sentinel
®knob
all the way to OFF.
If the knob was already in OFF, it must be cycled to ON
and back to OFF. Turn the knob clockwise to turn the
exterior lighting back on. The lamps will come back
on automatically when you put the transaxle in gear.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Fog Lamps
The fog lamps button is located below the twilight
knobs, to the left of the steering wheel on the
instrument panel.
Press this button to turn on and off the fog lamps. An
indicator light on the button will come on when the
fog lamps are on and go off when the fog lamps are off.
Your fog lamps will remain how you left them, on or
off, when you turn your vehicle off and then on again.
Your parking lamps will also come on automatically
while the fog lamps are active.
If your fog lamps are on when you use your high beams
or ash-to-pass feature, the fog lamps will be disabled
while the feature is being used.
Twilight Sentinel®
The Twilight Sentinel®will keep your headlamps on for
up to three minutes, to light your way when you
leave your vehicle.
To operate the Twilight Sentinel
®, turn the DELAY knob
located to the left of the steering column on the
instrument panel fully clockwise for the three-minute
delay. Turn it counterclockwise to reduce the delay. Turn
the knob to OFF to turn the Twilight Sentinel
®off.
At night, you can turn off all exterior lamps when you
are in PARK (P) by turning the Twilight Sentinel
®
knob all the way to OFF. If the knob was already in
OFF, it must be cycled to on then back to OFF, to turn
the exterior lighting off. The lamps will come back
on when you turn the knob clockwise.

If the Twilight Sentinel®lighting is active, it can be
disabled by turning on the manual parking lamps. This
lighting will be disabled until the key is turned from
ON or until the manual parking lamps are turned off.
Also, it is possible that your headlamps may go
out if you drive from a dark area into a bright area like a
lighted parking lot. If this happens, turn on your
headlamps with the exterior lamp control.
Exterior Lighting Battery Saver
If the exterior lamp control has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to OFF and a door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the exterior lamp control to turn the
lamps back on after turning the ignition to OFF and
opening a door. To delay the lamps from turning off, see
“Twilight Sentinel
®,” listed previously.
Instrument Panel Brightness
When it is dark outside, you can brighten or dim your
instrument panel cluster lights using the DIM knob,
located to the left of the steering wheel on the
instrument panel.
Turn the knob clockwise to brighten the instrument
panel cluster lights and displays. Turn the knob
clockwise all the way to turn on the interior courtesy
lamps. Turn the knob counterclockwise to dim the
instrument panel cluster lights and displays and to turn
off the courtesy lamps.
Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps will come on. They make it easier for you
to enter and leave the vehicle. Turn the DIM knob all
the way clockwise to turn the interior courtesy lamps on.

Entry Lighting
If it is dark enough outside and you press the unlock
button on the remote keyless entry transmitter, if
equipped, the interior courtesy lamps will come on and
stay on for about 25 seconds. The lamps will turn
off immediately by pressing the lock button on the
remote keyless entry transmitter, by turning the ignition
key to ON or by activating the power door locks.
If a door is left ajar, your interior lamps will turn off after
10 minutes to save your battery.
Delayed Entry Lighting
When you open the door to enter your vehicle, the
interior lamps will come on if it is dark enough outside.
When you close the door with the ignition off, the
interior lamps will stay on for 25 seconds or until the
ignition is turned on. Locking the doors with the power
door lock switch, or with the lock button on the
remote keyless entry transmitter, if equipped, will
override the delayed entry lighting and the lamps will
turn off immediately.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off after
you remove the key from the ignition.
Delayed Exit Lighting
This feature will turn on the interior lamps for 25 seconds
after you remove the key from the ignition while the
doors are closed and it is night. This will give you time
to nd the door handle or lock switches as you exit
the vehicle.
This lighting will only be deactivated if the key is
reinserted into the ignition switch or the power door
locks are activated.
Perimeter Lighting
When the unlock button on the remote keyless entry
transmitter, if equipped, is pressed, the DRL headlamps,
parking lamps and back-up lamps will turn on if it is
dark enough outside.

Front Reading Lamps
The front reading lamps, located on the headliner, will
come on as courtesy lamps when you open any of
the doors while it is dark outside. They will also come
on as part of the interior lighting features listed
previously.
To turn on a reading lamp when the doors are closed,
press either button. Press it again to turn the lamp off.
To avoid draining your vehicle’s battery, be sure to
turn off the reading lamps when leaving your vehicle.

Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
higher revolutions per minute (RPM) than normal to make
sure the battery charges. High electrical loads may occur
when several of the following are on: headlamps, high
beams, fog lamps, rear window defogger, fan on high
speed, heated seats, and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Monitor the battery voltage when in the BATTERY
SAVER ACTIVE mode.
If the voltmeter remains in the shaded area, below
11 volts, when driving then have the charging
system serviced immediately.
If the voltage increases above 12 volts then the
battery needs to be recharged. Try driving on
the highway with as few electrical accessories on
as possible.

HUD shows these images when they are lighted on the
instrument panel.
The speedometer may display a difference of 1.5 mph
(2.4 km/h) from the HUD image. This is normal.
When the ignition key is turned to ON, all possible HUD
images will come on, then the HUD will operate
normally.
If you never look at your instrument panel cluster, you
may not see something important, such as a warning
light. So be sure to scan your displays and controls and
the driving environment just as you would in a vehicle
without HUD.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image as
a parking aid.The HUD controls are located to the left of the steering
column.
1. Start your engine and turn the HUD INTENSITY
knob all of the way clockwise to MAX (Maximum).
The brightness of the HUD image is determined
by ambient light, and where you have set the HUD
INTENSITY knob.
