SERVICE ABS (Anti
-Lock Brake System): If the
SERVICE ABS message is displayed when you are driving,
stop as soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the message stays
on, or comes back on again while you are driving, your
vehicle is in need of service. If the regular brake system
warning light isn't on, you still have brakes, but don't have
anti
-lock brakes. If the regular brake system light is also on,
you don't have anti
-lock brakes and there is a problem with
your brakes. See ªBrake System Warning Lightº earlier in
this section.
If the SERVICE ABS message is being displayed, your
traction control system and the optional active handling
system will also be disabled. The driver information
center will scroll three messages: SERVICE ABS,
SERVICE TRACTION SYS and SERVICE ACTIVE

used to indicate to the driver that the Selective Real Time
Damping (SRTD) system has detected a malfunction and
that the system must be serviced. The SERVICE RIDE
CONTROL message will always come on when a failure
is detected by the Selective Real Time Damping (SRTD)
system. If a fault is present in the SRTD which causes the
shocks to be in their full soft condition, the SERVICE
RIDE CONTROL, SHOCKS INOPERATIVE and
MAXIMUM 80 MPH (129 km/h) will display together.
You will never get a SHOCKS INOPERATIVE and
MAXIMUM SPEED 80 MPH (129 km/h) message

Head-Up Display (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward the
front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Oil, Temperature and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine
speed of about 5,750 rpm, just prior to reaching the
engine fuel cut
-off mode. To better understand the
vehicle's power curves, see ªCapacities and
Specificationsº in the Index.

Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES icon will illuminate in
the HUD. View your Driver Information Center (DIC)
for more information.

Comfort Controls
This section tells you how to make your air system work
for you.
With these systems, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has
a flow
-through ventilation system described later in
this section.
Manual Comfort Controls
Fan Knob
The left knob controls the force of air you want.
Turn the knob clockwise to increase fan speed or
counterclockwise to decrease fan speed. The fan must be
turned on for the air conditioning compressor to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it counterclockwise
(toward the blue area) for cooler air. Turn it clockwise
(toward the red area) for warmer air.
Mode Knob
The right knob selects the location of where the air will
enter the vehicle.
UPPER: This setting directs most of the air
through the instrument panel outlets with a very small
amount of air directed to the lower outlets.
BI-LEVEL: This setting directs air into the
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the lower outlets.
LOWER: This setting directs most of the air
through the lower ducts to the floor area of the vehicle
with some of the air also directed toward the windshield
and side window vents.

3-6
As the interior of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI
-LEVEL).
A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather above 80
F (27
C) and you have set the driver
temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The fan will
start at a low speed momentarily to push the hot air to
the floor of the vehicle and then go to a higher fan speed
with cold airflow out of the instrument panel outlets. A
small amount of airflow will continue through the lower
ducts to cool the floor area.The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to your comfort set temperature,
the fan speed will decrease and the temperature output
may become warmer. The air intake may shift from
recirculation to outside air mode. If the interior
continues to cool due to a decrease in the amount of heat
the vehicle is absorbing from the sun or a decrease in the
outside temperature, the system could switch to other air
delivery modes (typically BI
-LEVEL or DEFOG).
Manual Settings
With the automatic electronic dual climate control
system, there are several manual settings you can use to
control the system and override the AUTO operation.
You can program the fan speed, air delivery mode, air
intake mode and control the air conditioning operation
using these settings. The system will still determine the
temperature output level based on the driver
-set
temperature and the passenger temperature offset.

3-7
FAN SPEED: Press the button with the fan symbol
on it to manually lock in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete AUTO from the digital display. The
fan graphics with the fan speed bars will be shown. To
increase the fan speed so that more air flows into the
vehicle, press the UP arrow on the fan switch. To
decrease the fan speed and airflow, press the DOWN
arrow. The AUTO button must be pressed to return to
the automatic fan control.
MODE: Press the MODE button to manually lock in the
current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.
UPPER: This setting directs most of the air
through the instrument panel outlets and a very small
amount to the lower outlets.
BI-LEVEL: This setting directs air into the
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the lower outlets.
LOWER: This setting directs most of the air to
the floor area and some of it toward the windshield and
side window vents.
DEFOG: This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears on the windshield or side glass due to rain or
snowy conditions.
Function Buttons
These buttons control climate control ON/OFF, air
intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system. This is the only setting that fully shuts
off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air intake mode while in OFF.
