5. TOW/HAUL Indicator Light — If EquippedThis light will illuminate when the TOW/
HAUL button has been selected. The TOW/
HAUL button is located in the center of the
instrument panel (below the climate controls).
6. Turn Signal Indicator The arrows will flash with the exterior turn signals
when the turn signal lever is operated. A tone will
chime, and an EVIC message will appear if the turn
signals are left on for more than 1 mile (1.6 km).
NOTE: If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
7. High Beam Indicator Indicates that headlights are on high beam.
8. Front Fog Light Indicator — If Equipped This indicator will illuminate when the front fog
lights are on. 9. Hill Descent Control Indicator Light — If Equipped
The symbol indicates the status of the Hill
Decent Control (HDC) feature. The lamp will
be on solid when HDC is armed. HDC can only
be armed when the transfer case is in the “4WD
Low” position and the vehicle speed is less then 30 mph
(48 km/h). If these conditions are not met while attempt-
ing to use the HDC feature, the HDC indicator lamp will
flash on/off.
10. Electronic Vehicle Information Center (EVIC)
Display/Odometer Display
The odometer display shows the total distance the ve-
hicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
4
UNDERSTANDING YOUR INSTRUMENT PANEL 287

as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. Refer to “Electronic Vehicle Information Cen-
ter”.
11. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.

25. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealership for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see “Main-
taining Your Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.

NOTE:
•Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
EVIC Amber Telltale Lights
This area will show reconfigurable amber caution tell-
tales. These telltales include:
•Forward Collision Warning (FCW) OFFThis light warns the driver of a potential colli-
sion with the vehicle in front and prompts the
driver to take action in order to avoid the
collision. For further information, refer to
“Adaptive Cruise Control (ACC)” in “Understanding
The Features Of Your Vehicle.”
•Air Suspension Up The air suspension up telltale will illuminate
when the air suspension is in use. For further
information, refer to “Starting And Operating”.
•Air Suspension DownThe air suspension down telltale will illumi-
nate when the air suspension is in use. For
further information, refer to “Starting And Op-
erating”.
•Low Fuel LightWhen the fuel level reaches approximately 3.0 gal
(11.0 L) this light will turn on, and remain on until
fuel is added.
•Loose Gascap Indicator If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator

NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the mobile phone antenna. This condition is
not harmful to the radio. If your radio performance does
not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during mobile phone operation when
not using Uconnect™ (if equipped).
CLIMATE CONTROLS
The air conditioning and heating system is designed to
make you comfortable in all types of weather.
Dual-Zone Manual Heating And Air Conditioning
The Dual-Zone Manual Climate Controls allow both
driver and front passenger seat occupants to select indi-
vidual comfort settings. The controls consist of a series of
outer rotary dials and inner push knobs.

NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser located in front of the radiator for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.

Mode Control (Air Direction)
Push the mode control buttons to choose from several
patterns of air distribution.
PanelAir is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct airflow.
NOTE: The center instrument panel outlets can be
aimed so that they are directed toward the rear seat
passengers for maximum airflow to the rear.
Bi-Level Air is directed through the panel and floor outlets.
NOTE: For all settings, except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions. Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and side
window demist outlets.
Mix Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to
the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.
Defrost Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.

NOTE:
•In Floor, Mix and Defrost modes a small amount of air
will flow through the outboard panel outlets for
occupant comfort.
•The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
Recirculation Control Pressing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are pres-
ent. Activating recirculation will cause the LED in the
control button to illuminate. NOTE:
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp
weather could cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
•The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
•The A/C can be deselected manually without disturb-
ing the mode control selection.
•When the ignition switch is turned to the LOCK
position or the ignition switch START/STOP button is
cycled to OFF, the recirculation feature will be
cancelled.
