a speed of 40 mph (64 km/h). At 40 mph (64 km/h), the
normal ESP stability function returns but TCS remains
off. When the vehicle speed drops below 35 mph (56
km/h), the ESP system shuts off. ESP is deactivated at
low vehicle speeds in 4WD low range so that it will not
interfere with off-road driving but ESP function returns
to provide the stability feature at speeds above 40 mph
(64 km/h). The9ESP/TCS Indicator Light9will always be
illuminated in 4WD low range when ESP is off.
NOTE:The ªESP OFFº message will display and the
audible chime will sound when the gear selector is
placed into the ªPº (Park) position from any other
position, and then moved out of the ªPº (Park) position.
This will occur even if the message was previously
clearedWARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The ªFull Offº mode is intended for off-
road use only.
TSC (Trailer Sway Control)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from

swaying. Always use caution when towing a trailer and
follow the tongue weight recommendations. Refer to
ªTrailer Towingº in Section 5 of this manual for more
information on towing a trailer with your vehicle. When
TSC is functioning, the ªESP/TCS Indicator Lightº will
flash, the engine power may be reduced and you may
feel the brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is disabled
when the ESP system is in the Partial Off or Full Off
modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
HSA (Hill Start Assist) (4WD Models with NV245
Two±Speed Transfer Case Only)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
148 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
²If you use a trailer brake controller with your
trailer, your trailer brakes may be activated and
deactivated with the brake switch. If so, when the
brake pedal is released there may not be enough
brake pressure to hold the vehicle and trailer on a
hill and this could cause a collision with another
vehicle or object behind you. In order to avoid
rolling down the hill while resuming acceleration,
manually activate the trailer brake prior to releas-
ing the brake pedal. Always remember the driver
is responsible for braking the vehicle.
²HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in P
(Park) and using the parking brake, it will roll
down the hill and could cause a collision with
another vehicle or object. Always remember to use
the parking brake while parking on a hill, and that
the driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to ªElec-
tronic Vehicle Information Center (EVIC)º in Section 4 of
this manual.
HDC (Hill Descent Control) (4WD Models with
NV245 Two±Speed Transfer Case Only)
HDC maintains vehicle speed while descending hills
during off-road driving situations and is available in 4
LOW range only. To enable HDC (transfer case must be in
4 LOW range), press the HDC switch. If the HDC switch
is pressed when the vehicle is not in 4 LOW range, the
light in the switch will flash for 5 seconds and HDC will
not be enabled.

Light/Brake Assist System (BAS) Warning Light
The ESP/BAS warning light in the instrument
cluster comes on when the ignition switch is
turned to the ªONº position. The light should
go out with the engine running. If the ESP/
BAS warning light comes on continuously with the
engine running, a malfunction has been detected in either
the ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at your authorized dealer
as soon as possible.
17. 4WD LOW Mode Indicator Light Ð If Equipped
This light alerts the driver that the vehicle is in
the 4WD LOW mode. The front and rear drive-
shafts are mechanically locked together forcing
the front and rear wheels to rotate at the same
speed.18. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 seconds as a bulb check.
During the bulb check, if the driver's seat belt is
unbuckled, a chime will sound. After the bulb check or
when driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Warning Light will flash
or remain on continuously. Refer to9Enhanced Driver
Seat Belt Reminder System (BeltAlert)9in the Occupant

Engine Oil Change Indicator System
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The ªOil Change Requiredº message
will flash in the EVIC display for approximately 10
seconds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the MENU button. To reset the oil change indica-
tor system (after performing the scheduled maintenance)
refer to the following procedure.
1. Turn the ignition switch to the ON position (Do not
start the engine).2. Fully depress the accelerator pedal slowly three times
within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.

The Trip Functions mode displays the following informa-
tion:
²Average Fuel Economy / Fuel Saver Mode (5.7L
Engine Only)
Shows the average fuel economy since the last reset.
When the fuel economy is reset, the display will read
ªRESETº or show dashes for two seconds. Then, the
history information will be erased, and the averaging will
continue from the last fuel average reading before the
reset.
Vehicles with the 5.7L Multi-Displacement System (MDS)
are equipped with the FUEL SAVER MODE in the Trip
Functions of the EVIC. The FUEL SAVER message willdisplay above the average fuel economy in the EVIC
display. This message will appear whenever MDS allows
the engine to operate on four cylinders, which will vary
depending on driving habits and vehicle usage.

This feature allows you to monitor when the MDS
switches off the fuel on four of the eight cylinders and it
can be used to modify driving habits in order to increase
the time in which the fuel saver mode is active.²Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. DTE cannot be reset through the FUNCTION
SELECT button.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
²When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will
change to a text display of9LOW FUEL.9This display
will continue until the vehicle runs out of fuel. Adding
a significant amount of fuel to the vehicle will turn off
the9LOW FUEL9text and a new DTE value will
display.
