2006 JEEP GRAND CHEROKEE ESP

When the detected obstacle is about 11.8 inches (30 cm)
from the rear fascia, the warning display will actuate a
continuous tone for about 10 seconds, and it will turn ON
all 8 LEDs, including both RED LEDs, on the correspond-
ing side of the display. The radio will be muted while the
tone is actuated.
When the obstacle is less than 11.8 inches (30 cm) from
the rear fascia, the warning display will either have all 8
LEDs ON (obstacle detected) or it will have only the
outermost LEDs ON with decreased brightness (obstacle
not detected), depending on the location of the obstacle.Enable/Disable the Rear Park Assist System
The Rear Park Assist System can be enabled and disabled
with a switch located in the switch bank of the instru-
ment panel.

CAUTION!
•The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.
WARNING!
•Drivers must be careful when backing up even
when using the Rear Park Assist System. Always
check carefully behind your vehicle, look behind
you, and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and must
continue to pay attention to your surroundings.
Failure to do so can result in serious injury or death.
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and hitch
ball assembly is disconnected from the vehicle when
the vehicle is not used for towing. Failure to do so
can result in injury or damage to vehicles or ob-
stacles because the hitch ball will be much closer to
the obstacle than the rear fascia when the warning
display turns the red LEDs ON. Also, the sensors
could detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.

To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:When driving uphill, at elevations above 2,000
feet (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. If the vehicle speed drops below 25 mph (40
km/h) for 5.7L models, or 30 mph (48 km/h) for 3.7L/
4.7L models, the Speed Control will automatically disen-
gage. If this happens, you can push down on the accel-
erator pedal to maintain the desired speed.
Vehicles may exhibit several 4-3 downshifts under the
above conditions. To reduce the frequency of the down-
shifts and to improve vehicle performance, it is advisable
to lock out overdrive. Press the TOW/HAUL switch on
the lower center switch bank (below the Heating/Air
Conditioning controls).WARNING!
Leaving the Speed Control ON when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the
system OFF when you aren’t using it.
Driving Up or Down Hills
When going up or down hills, it is possible for your
vehicle to lose or gain speed, even though the Speed
Control is engaged. The automatic transmission may also
downshift to a lower gear, to maintain speed going up or
down hills. If going down a hill steep enough to cause the
vehicle to gain speed, press the brake pedal, which will
disengage the Speed Control and help slow your vehicle.

NOTE:The optional cross rails have seven specific
locations identified by a feature on both the side rail and
the cross rail. Cross rails must be secured in one of the
seven detent locations on the side rail to prevent move-
ment with a sudden stop. For improved windnoise
performance when cross rails are not in use, place them
in detent positions #2 (second detent from the front of the
vehicle) and #7 (detent closest to the rear of the vehicle)
as indicated with a unique feature on the side rails.CAUTION!
•To prevent damage to the roof of your vehicle, DO NOT
carry any loads on the roof rack without cross rails
installed. The load should be secured and placed on top
of the cross rails, not directly on the roof. If it is
necessary to place the load on the roof, place a blanket
or some other protection between the load and the roof
surface.
•To avoid damage to the roof rack and vehicle, do not
exceed the rated load capacity of your cross rail system
or the roof rack system maximum load capacity of 150
lbs (68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
•Long loads which extend over the windshield, such as
wood panels or surfboards, should be secured to both
the front and rear of the vehicle.
•Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward loads. This is especially
true on large flat loads and may result in damage to the
cargo or your vehicle.

If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
8. Tachometer
The red segments indicate the maximum permissible
engine revolutions-per-minute (r.p.m. x 1000) for each
gear range. Before reaching the red area, ease up on the
accelerator.
9. Security Alarm System Indicator Light — If
Equipped
This light will flash rapidly for approximately 15 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower speed continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.10. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle, and shut off the engine as soon as possible. A
continuous chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked under the hood.
11. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
This indicator light starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The“ESP/TCS Indicator Light”also
flashes when TCS is active. If the“ESP/TCS
Indicator Light”begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
182 UNDERSTANDING YOUR INSTRUMENT PANEL

prevailing road conditions. The“ESP/TCS Indicator
Light”will flash any time the ESP or TCS is active and
helping to improve vehicle stability. If the“ESP/TCS
Indicator Light”is on solid, the ESP system has been
turned off by the driver or a temporary condition exists
that will not allow full ESP function. (See page 131 for
more information.)
12. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale. (See page 294 for more infor-
mation.)

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.
