Tilt Wheel
The tilt steering wheel allows you to adjust the steering
wheel before you drive. You can raise it to the highest
level to give your legs more room when you enter
and exit the vehicle.
The tilt lever is located on the driver’s side of the
steering column under the turn signal lever.
To tilt the wheel, hold the steering wheel and pull
the lever. Move the steering wheel to a comfortable
level, then release the lever to lock the wheel in place.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever will return
automatically.
To signal a lane change, raise or lower the lever for
less than one second until the arrow starts to ash.
This will cause the turn signals to automatically
ash three times. It will ash six times if the tow-haul
mode is active. Holding the turn signal lever for
more than one second will cause the turn signals to
ash until you release the lever. The lever will return
by itself when it is released.
An arrow on the instrument
panel cluster will ash
in the direction of the
turn or lane change.As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers will not see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and a blown
fuse. SeeInstrument Panel Fuse Block on page 5-109
andUnderhood Fuse Block on page 5-111.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the turn
signal and the message TURN SIGNAL ON will also
appear in the DIC. SeeDIC Warnings and Messages
on page 3-59. To turn the chime and message off, move
the turn signal lever to the off position.

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 a 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.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as Battery Saver Active or
Service Battery Charging System. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. SeeDIC Warnings
and Messages on page 3-59.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are left on
for more than 10 minutes when the ignition is in LOCK.
This will help prevent the battery from running down.

Climate Controls
Climate Control System
The heating, cooling, defrost, defog and ventilation of
your vehicle can be controlled with this system.
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 to the oor outlets. The
ow can be divided between vent and oor outlets
depending upon where the knob is placed between the
settings. A little air is directed towards the windshield
and side window outlets. Cooler air is directed to
the upper outlets and warmer air 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, side window outlets, and second row oor
outlets. In this mode, the system will automatically select
outside air. Recirculation cannot be selected when in
Floor Mode.
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 be on unless the
outside temperature is close to freezing.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob all the way counterclockwise to turn the
front system off.
:(Outside Air):Press this button to turn on the
outside air mode. When this mode is selected, air from
outside the vehicle will circulate throughout your vehicle.
An indicator light on the button comes on to show that it
is activated. The outside air mode can be used with
all modes, but it cannot be used with the recirculation
mode. Pressing this button again will cancel the
recirculation mode.
3-21

?(Recirculation):Press this button to turn on the
recirculation mode. When the button is pressed, an
indicator light will come on.
This mode keeps outside air from entering the vehicle. It
can be used to reduce outside air and prevent odors from
entering the vehicle. Recirculation may also help cool the
air inside your vehicle more quickly once the temperature
inside the vehicle is less than the outside temperature.
The recirculation mode cannot be used with oor, defrost,
or defogging modes. If you try to select recirculation in
one of those modes, the indicator light will ash three
times and turn off. The air conditioning compressor will
also come on when this mode is activated. While in
recirculation mode the windows may fog when the
weather is cold and damp. To clear the fog, select either
the defog or defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing the
button again, or turning off the engine.Temperature Control:Rotate the thumbwheels up or
down to increase or decrease the temperature on the
driver’s side or the passenger side of the vehicle for the
dual zone system, if equipped. Otherwise, turn the center
knob clockwise or counterclockwise to increase or
decrease the temperature inside the vehicle.
#(Air Conditioning):Press this button on the left
knob to turn the air conditioning system on or off. When
A/C is pressed, an indicator light comes on to show
that the air conditioning has been activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the vehicle while idling or after turning off the engine.
This is normal.
