Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. The steering wheel can be
raised to the highest level to give your legs more
room when you enter and exit the vehicle.
The tilt wheel lever is located on the left side of
the steering column.
To tilt the wheel, hold the wheel and pull the lever.
Then move the wheel to a comfortable position
and release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane Change Signals. See
Turn and Lane-Change Signals on page 154.
2Headlamp High/Low-Beam Changer.
SeeHeadlamp High/Low-Beam Changer on
page 155.
Flash-to-Pass. SeeFlash-to-Pass on page 155.
NWindshield Wipers. SeeWindshield Wipers
on page 155.
LQWindshield Washer. SeeWindshield
Washer on page 156.
For information on the headlamps, seeExterior
Lamps on page 160.

6(Delay):The wiper speed can be set for a long
or short delay between wiping cycles. This can
be very useful in light rain or snow. Turn the band
to choose the delay time. The closer to the top
of the lever, the shorter the delay.
6(Low Speed):Turn the band away from
you to the rst solid band past the delay settings,
for steady wiping at low speed.
?(High Speed):Turn the band further, to the
second solid band past the delay settings, for
high-speed wiping.
Windshield Washer
At the top of the multifunction lever, there is a
paddle with the windshield washer symbol on it.
Push the paddle to spray washer uid on the
windshield. The wipers run for several sweeps and
then either stop or return to the preset speed.
The ignition key must be in ACCESSORY or RUN
for this to work. SeeWindshield Washer Fluid
on page 333.
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
When the vehicle is low on washer uid, the
WASHER FLUID LOW ADD FLUID displays in the
Driver Information Center (DIC) for 60 seconds.
When the ignition is turned off, this message
displays again for three seconds to remind you
that the uid level is low.
Until the uid reservoir is relled, every time the
vehicle is started, the WASHER FLUID LOW ADD
FLUID message displays in the Driver Information
Center (DIC) for 60 seconds. Be sure to rell
the tank right away. SeeDIC Warnings and
Messages on page 199.

When it is dark enough outside, the low-beam
headlamps will turn off and the headlamps
and parking lamps will turn on. 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.
As with any vehicle, you should turn on the
regular headlamp system when it is needed.
Fog Lamps
-(Fog Lamps):If your vehicle has fog lamps,
the control is located on the exterior lamps
control. The exterior lamps control is located on
the instrument panel to the left of the steering
column.
The ignition must be in the ON position for the fog
lamps to come on.
To turn the fog lamps on, press the exterior lamps
button. A light will come on in the instrument
panel cluster. Press the exterior lamps button
again to turn the fog lamps off.When the headlamps are changed to high-beam,
the fog lamps also go off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Instrument Panel Brightness
D(Instrument Panel Brightness):The knob
with this symbol on it is located next to the exterior
lamps control. Push the knob in all the way until
it pops out and then turn the knob clockwise
to brighten or counterclockwise to dim the lights.
Push the knob back in when nished.
Courtesy Lamps
When a door is opened, the courtesy lamps
automatically come on. They make it easy for you
to enter and leave your vehicle. You can also
manually turn these lamps on by fully turning the
instrument panel brightness control clockwise.
The reading lamps, located on the rearview
mirror, can be turned on or off independent of the
automatic courtesy lamps, when the doors
are closed.
163

Dome Lamp
The dome lamp will come on when you open a
door. You can also turn this lamp on by turning the
instrument panel brightness control clockwise.
Entry Lighting
Your vehicle may have courtesy lamps that will
come on and stay on for a set time whenever the
unlock symbol is pressed on the Remote
Keyless Entry (RKE) Transmitter, if the vehicle
has one.
If a door is opened, the lamps will stay on while it
is open and then turn off automatically about
25 seconds after the door is closed. If the unlock
symbol is pressed and you do not open a
door, the lamps will turn off after about
20 seconds.
Entry lighting includes a feature called theater
dimming. With theater dimming, the lamps do not
turn off at the end of the delay time. Instead,
they slowly dim after the delay time until they go
out. The delay time is canceled if you turn the
ignition key to ON or press the power door
lock switch. The lamps will dim right away.When the ignition is on, illuminated entry is
inactive, which means the courtesy lamps will not
come on unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will
continue to work until one of the following occurs:
The ignition is in ON.
The doors are locked.
An illumination period of 25 seconds has
elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
164

Delayed Exit Lighting
This feature illuminates the interior for a period of
time after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON.
The power door locks are activated.
An illumination period of 20 seconds has
elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the
dimming of the instrument panel displays during
the daylight while the headlamps are on so
that you will still be able to see the displays.
Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on
and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.
165

Manual Operation
Turn the right knob clockwise or counterclockwise
to direct the airow inside of the vehicle.
To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets and the other half
to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed
to the windshield and side window outlets.
In this mode, the system will automatically
select Outside Air.
The right knob can also be used to select defog
or defrost mode. For more information, see
“Defogging and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
The air conditioning compressor will operate
unless the outside temperature is 40°F (4°C)
or below.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the
fan speed. If the airow seems low when the
fan is at the highest setting, the passenger
compartment air lter may need to be replaced.

Compartment Air Filter on page 173and
Scheduled Maintenance on page 408.
