2009 JEEP COMMANDER 4WD

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.
Full Off (4WD Models Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the ESP OFF switch for five
seconds when the vehicle 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 Electronic Vehicle Information Center (EVIC).
Refer to “Electronic Vehicle Information Center (EVIC)”
in Section 4 of this manual for more information.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 deactivated at low vehicle speeds 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). The ESP/TCS Indicator Light will always be
illuminated when ESP is off. To turn ESP on again,
momentarily depress the ESP OFF switch. This will
restore the normal “ESP On” mode of operation.
NOTE:The “ESP OFF” message will display, and the
audible chime will sound, when the shift lever is placed
in 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.

WARNING!
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 “Full Off” ESP mode is intended for
off-road use only.
4WD Low Range
Full Off
This is the normal operating mode for ESP 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
ESP system will be in this “Full Off” mode. In 4WD LOW
range, 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 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). The ESP/TCS Indicator Light
will always be illuminated in 4WD LOW range when ESP
is off.
NOTE:The “ESP OFF” message will display, and the
audible chime will sound, when the shift lever is placed
in 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
330 STARTING AND OPERATING

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.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
•Vehicle must be on a 8% 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.
WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
332 STARTING AND OPERATING

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
4WD LOW range only. To enable HDC (transfer case
must be in 4WD LOW range), press the HDC switch. If
the HDC switch is pressed when the vehicle is not in
4WD LOW range, the light in the switch will flash for five
seconds and HDC will not be enabled.
When HDC is properly enabled, the message “HILL
DESCENT CONTROL” will appear in the EVIC and the
light in the switch will be illuminated. HDC will auto-
matically apply the brakes to control downhill speed
when necessary. HDC has the capability to sense terrain

Towing — Quadra-Trac I(Single-Speed Transfer
Case) 4WD Models
Recreational towing is not allowed.This model does not
have a NEUTRAL position in the transfer case.
Towing — Quadra–Trac II/Quadra–Drive II4WD
Models
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
NOTE:The transfer case must be in the NEUTRAL
position, and the transmission must be in the PARK
position for recreational towing.
Shifting Into NEUTRAL
Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL before recre-
ational towing to prevent damage to internal parts.
1. Depress the brake pedal.
2. Turn the ignition key ON, engine off.
3. Shift the transmission into NEUTRAL.
4. Shift the transfer case into NEUTRAL.
