tion if this occurs. Next, press the switch forward and
release to Express Close.Pinch Protect OverrideIf a known obstruction (ice, debris, etc.) prevents closing,
press the switch forward and hold for two seconds after
the reversal occurs. This allows the sunroof to move
towards the closed position.
NOTE:Pinch protection is disabled while the switch is
pressed.Venting Sunroof — ExpressPress and release the Vbutton, and the sunroof will
open to the vent position. This is called “Express Vent”,
and will occur regardless of sunroof position. During
Express Vent operation, any movement of the switch will
stop the sunroof.
Sunshade OperationThe sunshade can be opened manually. However, the
sunshade will open automatically as the sunroof opens.
NOTE: The sunshade cannot be closed if the sunroof is
open.Wind BuffetingWind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.UNDERSTANDING THE FEATURES OF YOUR VEHICLE 161

AUTO, the ESP system will be in this mode. This mode
should be used for almost all driving situations. ESP
should only be turned to “Partial Off” or “ESP Off” for
specific reasons as noted below.ESP Partial Off
This mode is entered by momentarily depressing the ESP
OFF switch. When in
Partial Offmode, the TCS portion
of ESP, except for the “limited slip” feature described in
the TCS section, has been disabled and the ESP/TCS
Indicator Light will be illuminated. All other stability
features of ESP function normally. This mode is intended
to be used if the vehicle is in deep snow, sand, or gravel
conditions and more wheel spin than ESP would nor-
mally allow is required to gain traction. To turn ESP on
again, momentarily depress the ESP OFF switch. This
will restore the normal “ESP On” mode of operation.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is

overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
WARNING!
In the “Partial Off” mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.All 4WD vehicles in Auto and 4HI Modes can also
choose the following ESP operating mode. This is
the only ESP operating mode in 4LO:Full Off
This mode is intended for off-road use when ESP stability
features could inhibit vehicle maneuverability due to trail
conditions. This mode is entered by depressing and
holding the ESP OFF switch for five seconds when thevehicle is stopped and the engine is running. After five
seconds, the “ESP/TCS Indicator Light” will illuminate
and the “ESP OFF” message will appear in the odometer.
Press and release the trip odometer button located on the
instrument cluster to clear this message.
NOTE:
The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed
into the PARK position from any other position, and then
moved out of the PARK position. This will occur even if
the message was previously cleared.
In this mode, ESP and TCS, except for the “Limited Slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h), the system returns to “Partial Off”
mode, described above. When the vehicle speed drops
below 35 mph (56 km/h), the ESP system shuts off. ESP
is off at low vehicle speeds so that it will not interfere
with off-road driving but ESP function returns to provide

TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF
EQUIPPEDThe Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire inflation placard pressure. The
placard pressure is defined on the Tire and Loading
Information label. The Tire and Loading Information
label is located on the drivers side B-pillar. Vehicles
equipped to be operated in either the “max load inflation
pressure” condition described on the Tire and Loading
Information label or the alternative “light load inflation
pressure” condition described on the Supplemental Tire
Pressure Information label, may also be equipped with a
“Tire Light Load Inflation” switch to choose the appro-
priate TPMS low pressure warning threshold levels
based upon the vehicle load condition. The Supplemental
Tire Pressure Information label is located on the rear face
of the driver door. Operation of the “Tire Light Load
Inflation” switch is described later in this manual section.The tire pressure will vary with temperature by approxi-
mately 1 psi (6.9 kPa) for every 12°F (6.5°C). This means
that when the outside temperature decreases, the tire
pressure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after a vehicle has not been driven for
more than three hours, or driven less than 1 mile (1.6 km)
after a three-hour period. For information on how to
properly inflate the vehicle’s tires, refer to ”Tire Pressure”
under “Tires – General Information” in this section. The
tire pressure will also increase as the vehicle is driven -
this is normal and there should be no adjustment for this
increased pressure.
The TPM System will warn the driver of a low tire
pressure if the tire pressure falls below the low pressure
warning threshold for any reason, including low tem-
perature effects, or natural pressure loss through the tire.366 STARTING AND OPERATING

the max load inflation pressure (cold) values to switch
the TPMS system to the max load inflation pressure
(cold) low pressure warning threshold. If after pressing
the tire light load inflation switch, and tire pressures are
below the max load inflation pressure (cold) low pressure
warning thresholds, the TPMS low pressure warning
telltale light (located in the instrument cluster) will turn
ON and a chime will sound. The tire pressures are now
required to be inflated to the max load inflation pressure
(cold) values described on the Tire and Loading Informa-
tion label. The Tire and Loading Information label is
located on the drivers side B-pillar. If the tire light load
inflation switch LED turns OFF, the TPMS has been reset
and the TPMS is using the max load inflation pressure
(cold) low pressure warning thresholds.Tire Pressure Monitor System ComponentsThe Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors tomonitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:
It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The Tire Pressure Monitoring System (TPMS) consists of
the following components:
•
Receiver Module
•
Four Wheel Sensors
•
Two Trigger Modules (mounted in the front wheel-
wells)
•
Tire Light Load Inflation Switch (located in the instru-
ment panel)
•
