Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it will
adjust your vehicle’s speed and maintain the following
distance (gap) selected.
Use the GAP button on
the steering wheel to
adjust the follow distance
between your vehicle
and other vehicles.
Press the top of the button to increase the distance or
the bottom of the button to decrease the distance.
The rst button press shows the current follow distance
setting on the HUD. The current following distance
setting is maintained until it is changed.
There are six follow distances to choose from.
The follow distance selection ranges from near to far
(1 second to 2 seconds follow time). The distance
maintained for a selected follow distance varies based
on vehicle speed. The faster the vehicle speed thefurther back you will follow. Consider traffic and
weather conditions when selecting the follow distance.
The range of selectable distances may not be
appropriate for all drivers and driving conditions. If you
prefer to travel at a following distance farther than
Adaptive Cruise Control allows, disengage the system
and drive manually.
A graphic on the HUD indicates the selected following
distance. This picture shows a maximum follow distance.
The vehicles will move closer together as you select a
smaller following distance.

{CAUTION:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Do not use Adaptive Cruise Control when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” later in
this section.
Adaptive Cruise Control automatically slows the vehicle
down when approaching a slower moving vehicle.
It then adjusts your speed to follow the vehicle in front
at the selected following distance. Your speed increases
or decreases to follow the vehicle in front of you, but
will not exceed the set speed. It may apply limited
braking, if necessary. When braking is active, the brake
lights come on. It may feel or sound different than if
you were applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not use Adaptive Cruise
Control when approaching stationary or
slow-moving vehicles or other objects.
{CAUTION:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. Your vehicle may accelerate
toward objects, such as a stopped vehicle that
suddenly appears after the lead vehicle changes
lanes. Your complete attention is always required
while driving and you should be ready to take
action and apply the brakes.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds and the multifunction lever is
in the AUTO position. SeeExterior Lamps on page 3-26.
When the exterior lamp control has been turned off or is
in the parking lamp position and the wiper control is
on delay, low speed or high speed, the HEADLAMPS
SUGGESTED message will appear on the Driver
Information Center (DIC).
When the ignition is turned off, the wiper-activated
headlamps will immediately turn 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.
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 DRL 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 exterior lamp control is in the off position.
The transmission is not in P (Park).
When DRL are on, only the front turn signal lamps are
on. No other exterior lamps such as the parking
lamps, taillamps, etc. are on when the DRL are used.
The instrument panel is not be lit up either.
When it is dark enough outside, the front turn signal
lamps turn off and normal low-beam headlamps turn on.
When it is bright enough outside, the regular lamps
go off, and the front turn signal lamps take over. If the
vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if
it is light outside. During that delay, the instrument panel
cluster might not be as bright as usual. Make sure the
instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-30
for more information.

Twilight Sentinel®
This feature can turn the 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
AUTO position.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes 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 control is in full bright
position. SeeInstrument Panel Brightness on page 3-30
for more information.You can idle the vehicle with the lamps off, even when
it is dark outside. After starting the vehicle, turn the
exterior lamp control band to off, then release it.
The lamps will remain off until you turn the control
band to off again.
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, the
lamps will remain on until:
The exterior lamp switch is moved from OFF to the
parking lamp position, or
the delay time selected has elapsed.
SeeDriver Information Center (DIC) on page 3-57to
select the delay time. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
The regular headlamp system should be turned on
when needed.

Battery Run-Down Protection
The vehicle has a feature to help prevent the battery
from being drained, in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console,
or glove box lamps are accidentally left on, or something
is left plugged into the accessory power outlet or
cigarette lighter. If any of the accessory lamps are
left on, they will automatically time-out after about
10 minutes. To reset the battery protection, all of the
above lamps must be turned off or the ignition must be
in the ACC/ACCESSORY position.
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 the instrument
panel cluster.
The information may be displayed in English or metric
units and appears as an image focused out toward
the front of the vehicle. To change from English to metric
units, seeDriver Information Center (DIC) on page 3-57.
The HUD consists of the following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Tap-Up/Tap-Down Transmission Feature
Check Gages Message
Adaptive Cruise Control Features and Indicators

Climate Controls
Dual Climate Control System
With this system the heating, cooling, and ventilation for
the vehicle can be controlled.
When the vehicle is rst started, the system will recall the
last temperature fan and mode settings for that driver.

Power/Temperature
Buttons
B. Heated Seats
C. Recirculation
D. Defrost
E. Rear Window DefoggerF. Display

H. Fan Control
I. Air Delivery Mode
Control
J. Air Conditioning Off
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system automatically controls
the temperature, air delivery mode, air conditioning
compressor and the fan speed. AUTO will appear on
the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C). An initial
setting of 73°F (23°C) is suggested.
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool
any faster. If the system is set at the warmest
or coldest temperature setting, the system remains
in manual mode at that temperature and it will
not go into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system starts
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 the 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.
3-36

To change the current mode, select one of the following:
H(Vent):Air is directed to the instrument panel
outlets.
%(Bi-Level):Air is divided between the instrument
panel and oor outlets. In automatic operation, cooler air
is directed to the upper outlets and warmer air to the
oor outlets.
6(Floor):Air is directed to the oor outlets, with
some air directed to the windshield and side window
outlets.
-(Floor/Defog):This mode clears windows of fog or
moisture. Air is directed to the windshield, oor
outlets and side windows. In this mode, the system
turns off recirculation and runs the air conditioning
compressor unless the outside temperature is near or
below freezing.
1(Defrost):This mode removes fog or frost from the
windshield more quickly. Press to direct air to the
windshield, with some air directed to the side windows.In this mode, the system automatically turns off the
recirculation and runs the air conditioning compressor,
unless the outside temperature is near or below freezing.
Do not drive the vehicle until all the windows are clear.
A/C OFF (Air Conditioning):Press to turn off the air
conditioning compressor. Press AUTO to return to
automatic operation. The compressor cannot be turned
off in either the defrost or oor/defog mode.
?(Recirculation):Press to turn the recirculation
mode on or off. The air conditioning compressor
also comes on.
This mode recirculates and helps to quickly cool the
air inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.
Recirculation is not available in defrost or oor/defog
modes.
Using recirculation for long periods of time may cause
the air inside the vehicle to become too dry. To prevent
this from happening, after the air in the vehicle has
cooled, turn the recirculation mode off.

Fuel Gage
The fuel gage indicates
about how much fuel is left
when the ignition is
turned on.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
When the needle approaches the low fuel symbol, LOW
FUEL will appear on the Driver Information Center (DIC)
display. At this time, there is still have a little fuel left,
but the vehicle’s fuel tank should be lled soon.Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in
10 minutes if fuel has not been added to the vehicle.
Here are ve things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads the full symbol.
It takes more (or less) fuel to ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank’s
capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty when
the ignition is turned off.
The gage reading may change slightly within the
rst several minutes after starting the vehicle.
