2006 JEEP GRAND CHEROKEE 4WD

WARNING!
ESP (Electronic Stability Program) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESP cannot prevent acci-
dents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESP-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user’s safety or the safety of others.
The ESP system has 3 available operating modes in 4WD
High Range and in 2WD vehicles. The system has 2
operating modes in 4WD Low Range.
High Range (4WD Models) or 2WD Models
On
This is the normal operating mode for ESP in 4WD high
range and in 2WD vehicles. Whenever the vehicle is
started or the transfer case (if equipped) is shifted from
4WD low range or neutral back to 4WD high range, the
ESP system will be in this mode. This mode should be
used for most all driving situations. ESP should only be
turned to“Partial Off”or“Full Off”for specific reasons
as noted below.
Partial Off
This mode is entered by momentarily depressing the
ESP Control Switch. When inPartial 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 Lightwill 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,

Vehicle Information Center (EVIC). Refer to“Electronic
Vehicle Information Center (EVIC)”in Section 4 of this
manual. (See page 187 for more information.) To turn ESP
on again, momentarily depress theESP Control 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 gear selector is
placed into the“P”(Park) position from any position
other than“P”(Park), and then moved out of the“P”
(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-highway or off-road use only.
4WD Low Range
Partial 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 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
138 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

30 mph (48 km/h). At 30 mph (48 km/h), the normal ESP
stability function returns but TCS remains off. When the
vehicle speed drops below 25 mph (40 km/h), the ESP
system shuts off. ESP is off 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 30 mph (48 km/h). TheESP/
TCS Indicator Lightwill always be illuminated in 4WD
low range when ESP is off.
Full Off
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 Control Switch”for 5
seconds when the vehicle is stopped and the engine is
running. In this mode, all ESP and TCS stability features
are turned off except for the“limited slip”feature de-
scribed in the TCS section. After 5 seconds, a chime will
sound, and the“ESP OFF”message will appear in theElectronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)”in Sec-
tion 4 of this manual. (See page 187 for more informa-
tion.) To turn ESP on again, momentarily depress the
“ESP Control Switch”. This will restore the normal“Par-
tial Off”mode of operation in 4wd low range.
NOTE:The“ESP OFF”message will display and the
audible chime will sound when the gear selector is
placed into the“P”(Park) position from any position
other than“P”(Park), and then moved out of the“P”
(Park) position. This will occur even if the message was
previously cleared.

16. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light—If
Equipped
The ESP/BAS warning light in the instrument
cluster comes on when the ignition switch is
turned to the“ON”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. (See page 131 for more information.)
17. 4WD LOW Mode Indicator Light—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. (See page 262 for more information.)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 toEnhanced Driver
Seat Belt Reminder System (BeltAlert)in the Occupant
Restraints section for more information.
19. Cruise Indicator Light
This indicator lights when the speed control
system is turned ON.
20. Odometer
The odometer shows the total distance the vehicle has
been driven.

Shifting Procedures
4HIto4LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
key ON or engine running, shift the transmission into N
(Neutral), and raise the transfer case T-handle.“The 4WD
LOW Indicator Lamp”in the instrument cluster will
begin to flash and remain on solid when the shift is
complete. Release the T-handle.
NOTE:If shift conditions/interlocks are not met, or a
transfer case motor temperature protection condition
exists, a“CHECK SHIFT PROCEDURES”message will
flash from the EVIC (Electronic Vehicle Information Cen-
ter). Refer to“Electronic Vehicle Information Center
(EVIC)”in Section 4 of this manual. (See page 187 for
more information.)
