Daytime Running Lamps
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 first sold in Canada.
The DRL system will come on when the following
conditions are met:

the ignition is on,

the exterior lamps control is in automatic
headlamp mode,

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the
last chosen headlamp setting that was used.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate,
provided it is not dark outside.
To idle an automatic transmission equipped vehicle with
the DRL off, set the parking brake. Shifting the
transmission into PARK (P) will also allow you to idle
the vehicle with the DRL off. The DRL will stay off
until you release the parking brake or shift the
transmission out of PARK (P).
To idle a manual transmission equipped vehicle with the
DRL off, set the parking brake. The DRL will stay off
until you release the parking brake.
The following procedure applies only to vehicles first
sold in the United States.

When necessary, you may turn off the Automatic
Headlamp System and the Daytime Running Lamps
(DRL) feature by following these steps:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you the system
is off. The system will revert back to the automatic
mode when the ignition is turned off and on again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(the chime will sound), or turn the ignition off and
on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Fog Lamps (If Equipped)
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamp button is
located on the left side of
your instrument panel.
Your parking lamps and/or low
-beam headlamps must
be on for your fog lamps to work.

2-70
Press the button to turn the fog lamps on. Press the
button again to turn them off. An indicator light will
glow in the button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use the fog lamps in the
dark without turning on the headlamps.
The fog lamps will go off whenever the high
-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the fog
lamp button again.
Auxiliary Roof Mounted Lamp Switch
(If Equipped)
If your vehicle has this feature, this switch includes
wiring provisions for a dealer or a qualified service
center to install an auxiliary roof lamp.
This switch is located
on the center of the
instrument panel near
the comfort controls.
When the switch wiring is connected to an auxiliary roof
mounted lamp, pressing the switch will activate the
lamp and illuminate an indicator light near the switch.
Pressing the switch again will turn off the roof
mounted lamp.
If your vehicle has this switch, your vehicle may have
the snow plow prep package. For further information see

Electrochromic Mirror Operation
The time period you need to press and hold the TEMP
button to turn the electrochromic feature on or off is
six seconds. The indicator light to the right of the TEMP
button will still turn on or off to show you when the
electrochromic feature is activated. Once the mirror is
turned off, it will remain off until it is turned back on, or
until the vehicle is restarted.
Compass Operation
Press the COMP button once briefly to turn the compass
on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause the
liquid cleaner to enter the mirror housing.Compass Calibration
The compass may need calibration if one of the
following occurs:

After five seconds, the display does not show a
compass heading (N for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.

The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
in the COMP button for approximately eight seconds or
until CAL is displayed.
The compass can be calibrated in one of two ways:

Drive the vehicle in circles at five mph (8 km/h) or
less until the display reads a direction, or

drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.

Electrochromic Mirror Operation
The electrochromic (self dimming) mirror function is
turned on automatically each time the ignition is started.
To operate the electrochromic mirror do the following:
1. Make sure the green indicator light, located to the
left of the on/off button, is lit. If it's not, press and
hold the on/off button for six seconds until the green
light comes on, indicating that the mirror is in
electrochromic (self dimming) mode.
2. Turn off the electrochromic mirror function by
pressing and holding the on/off button for
six seconds until the green indicator light turns off.
Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside of zone eight.
Under certain circumstances, as during a long distance
cross
-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth's magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance do the following:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold the on/off button for nine seconds or
until a Z and a zone number appears in the display.
The compass is now in zone mode.
3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After about four seconds of inactivity, the
new zone number will be locked in and the
comp/temp display will return.
4. Calibrate the compass as described below.

Your instrument cluster is designed to let you know at a
glance how your vehicle is running. You'll know how
fast you're going, about how much fuel you have and
many other things you'll need to know to drive safely
and economically.
Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
Press the reset button to toggle between the trip
odometer and the regular odometer. Holding the reset
button for two seconds while the trip odometer is
displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.Engine Hour Meter Display
The odometer can also display the number of hours the
engine has run. To display the hour meter, turn the
ignition off, press and hold the reset button for at least
four seconds. The hour meter will be displayed for up to
30 seconds, or until the ignition is turned on.Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
NOTICE:
On vehicles with a manual transmission, if
you operate the engine with the tachometer in
the red area, your engine or other parts could
be damaged.
Damage to your engine or vehicle caused by
operating the engine in the red area isn't covered
by your vehicle warranty. Don't operate the
engine with the tachometer in the shaded area.
