Decreasing Set Speed While Using
Adaptive Cruise Control
Press the SET button until you reach the lower speed
you want, then release it.
To slow down in very small amounts, briey press the
SET button. Each time you do this, your set speed
will decrease by 1 mph (1 km/h) slower.
Resuming a Set Speed
Suppose you set your Adaptive Cruise Control at a
desired speed and then you apply the brake. This will
disengage the Adaptive Cruise Control. But you do
not need to reset it.
Once you are going about 25 mph (40 km/h) or more,
press the RES button. Adaptive Cruise Control will
be engaged with the previously chosen set speed.
Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it will
adjust your vehicle’s speed and maintain the follow
distance (gap) you select.Use the plus and minus buttons on the steering wheel
to adjust the follow distance.
Press the plus button to increase the distance or the
minus button to decrease the distance. The rst button
press will show you the current follow distance
setting on the DIC. Your current follow distance setting
will be maintained until you change it.
There are six follow distances to choose from. The
follow distance selection ranges from near to far
(one second to two seconds follow time). The distance
maintained for a selected follow distance will vary
based on vehicle speed. The faster the vehicle speed
the further back your vehicle 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 follow distance farther than
Adaptive Cruise Control allows, disengage the
system and drive manually.

Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem with
the Adaptive Cruise Control. SeeDIC Warnings and
Messages on page 3-76for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use Adaptive Cruise Control
in icy conditions, or when visibility is low, such as in fog,
rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to engage
the Adaptive Cruise Control. If you are unable to do
so, see your dealer.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the
left of the steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
Fog Lamps
The exterior lamps control has four positions:
O(Off):Turn the control to this position to turn off the
exterior lamps except for Daytime Running Lamps (DRL).
3-30

To idle your vehicle with the DRL off at night, turn off
automatic lighting and shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).
To drive your vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or fog
lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
-(Fog Lamps):Your vehicle is equipped with fog
lamps. It is located on the exterior lamps control.
The exterior lamps control is located on the instrument
panel to the left of the steering column.
When you press the exterior lamps control, the fog lamp
lights on the instrument panel cluster will come on to
indicate that the front and rear fog lamps and the parking
lamps are on.
Press the button again to turn them off.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They will turn back on again when you
switch to low-beam headlamps.When automatic lighting is on and the fog lamps are
turned on, the fog lamps, headlamps and parking lamps
will remain on.
The ignition must be on for the fog lamps to operate.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn with the
multifunction lever. They provide more light for
cornering.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately
10 minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on.
The battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on.

Sensors
The solar sensor, located in the defrost grille, middle of
the instrument panel, monitors the solar radiation.
Do not cover the solar sensor or the system will not
work properly.There is also an interior temperature sensor located
next to the steering wheel that measures the
temperature of the air inside your vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false reading in the displayed temperature.
3-48

If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound.
Here are a few concerns some owners have had about
the fuel gage. All of these situations 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 full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may have
indicated that the tank was half full, but it actually
took a little more or less than half the tank’s capacity
to ll the tank.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC
is also used to display warning/status messages. All
messages will appear in the DIC display located at
the bottom of the instrument panel cluster, below the
tachometer and speedometer. The DIC buttons are
located on the instrument panel, to the left of the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The top line of the DIC display shows the vehicle system
information and the warning/status messages. The
bottom line of the DIC display shows the odometer on
the left side. The bottom line of the DIC display also
shows a digital speedometer on the right side.
If a problem is detected, a warning message will appear
on the display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.
