394 STARTING AND OPERATING

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions. When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Paddle Shift
switches (refer to
Paddle Shift Mode in this section) to
select a lower gear. Under these conditions, using a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
SPORT (S)
This mode alters the transmission’s automatic shift
schedule for sportier driving. Upshift speeds are in-
creased to make full use of available engine power. To
5
STARTING AND OPERATING 409

4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Paddle Shift Mode
Paddle Shift mode is a driver-interactive transmission
feature providing manual shift control, giving you more control of the vehicle. Paddle Shift allows you to maxi-
mize engine braking, eliminate undesirable upshifts and
downshifts, and improve overall vehicle performance.
This system can also provide you with more control
during passing, city driving, cold slippery conditions,
mountain driving, trailer towing, and many other situa-
tions.
Operation
When the transmission is in DRIVE or SPORT mode, it
will operate automatically, shifting between the eight
available gears. To engage Paddle Shift mode, simply tap
one of the steering wheel-mounted shift paddles (+/-)
while in DRIVE or SPORT mode. Tapping (-) to enter
Paddle Shift mode will downshift the transmission to the
next lower gear, while using (+) to enter Paddle Shift
mode will retain the current gear. When Paddle Shift
mode is active, the current transmission gear is displayed
in the instrument cluster.

STARTING AND OPERATING 411

CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Traction Control System (TCS), Brake
Assist System (BAS), Electronic Roll Mitigation (ERM),
and Electronic Stability Control (ESC). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.Also, your vehicle may be equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Ready Alert
Braking (RAB), Rain Brake Support (RBS) and, if it has
four-wheel drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC), Selec Speed Control
(SSC).
Anti-Lock Brake System
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.
446 STARTING AND OPERATING

WARNING!
•When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the “ESC Off Indicator Light” will be illuminated.
When in “Partial Off” mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC sys-
tem is reduced.
• Trailer Sway Control (TSC) is disabled when the
ESC system is in the Partial Offmode.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in 4WD LOW
range. Whenever the vehicle is started in 4WD LOW
range, or the transfer case (if equipped) is shifted from 4WD HIGH range or NEUTRAL to 4WD LOW range, the
ESC system will be in the “Partial Off” mode.
Trailer Sway Control (TSC)
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. Note that TSC cannot stop
all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations. Refer to “Trailer Towing” in this sec-
tion for further information. When TSC is functioning,
the “ESC Activation/Malfunction Indicator Light” 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 ESC system is in the “Partial Off” mode.
5
STARTING AND OPERATING 453

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.
Hill Start Assist (HSA)
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 the
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
• Vehicle must be on a 6% (approximate) grade or
greater hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.
