2010 JEEP GRAND CHEROKEE stop start

WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should apply
the park brake, shift the transmission into PARK,
and remove the key fob from the ignition switch.
Once the key fob is removed from the ignition
switch, the shift lever is locked in the PARK position,
securing the vehicle against unwanted movement.
Furthermore, you should never leave children unat-
tended inside a vehicle.
REVERSE
This range is for moving the vehicle backward. Use only
after the vehicle has come to a complete stop.
NEUTRAL
This range is used when vehicle is standing for pro-
longed periods with engine running. Engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range should only be selected when the vehicle is at
a complete stop and the brakes are firmly applied. The
transmission automatically upshifts through fifth gear.
The DRIVE position provides optimum driving charac-
teristics under all normal operating conditions. For addi-
tional shifting information, refer to “AutoStick”in
“Starting and Operating” for further information.
Rocking the Vehicle
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the shift lever
between DRIVE and REVERSE, while applying slight
pressure to the accelerator.
244 STARTING AND OPERATING

Operation
By placing the shift lever in the DRIVE position, the shift
lever can be moved from side to side. This allows the
driver to engage the AutoStickmode. Moving the shift
lever to the right (+) or the left (-) will engage the
AutoStick mode. In normal driving mode (Boxed “D”
displayed in the PRNDL), moving the shift lever to the
right (+) will engage the AutoStick mode putting the
transmission in the currently engaged gear. Moving the
shift lever to the Left (-) will engage the AutoStick mode
and downshift the transmission one gear. For example, if
the transmission is in Drive mode (a boxed Dis
displayed in the cluster) and is operating in third gear,
tapping the shift lever to the right (+) will engage
AutoStick mode (while remaining in third gear) and a
boxed 3will be displayed in the cluster. Tapping the
shift lever to the left (-) would also engage AutoStick 
mode, but would force a downshift to second gear, and display a boxed
2in the cluster. Once AutoStick mode
is engaged, a move to the right (+) or left (-) will trigger
a upshift (+) or trigger a downshift (-).
NOTE: In the AutoStick mode, the transmission will
shift up and down when left or right (D-/D+) is manu-
ally selected by the driver.
The transmission will not allow a downshift if the
downshift would result in an engine overspeed condi-
tion. The transmission will always allow a upshift from
first to second gear, however 2nd - 3rd, 3rd - 4th, and 4th
– 5th upshifts will not be allowed if the vehicle speed is
too low to maintain operation in the selected gear. The
transmission will automatically downshift as the vehicle
slows to a stop (to prevent engine lugging) and will
display the current gear. After a stop, the driver should
manually upshift (D+) the transmission as the vehicle is
accelerated.
246 STARTING AND OPERATING

When in the AutoStickmode, as the engine RPM nears
the engine maximum speed, an “UPSHIFT” message will
appear in the Electronic Vehicle Information Center
(EVIC) portion of your instrument cluster. This message
appears in order to alert the driver that the engine speed
is approaching it’s maximum value and a upshift to the
next gear is required. In the event that the driver does not
upshift, the engine control system will automatically do it
for the driver. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
Shifting into or out of the AutoStick mode can be done
at any time without taking your foot off the accelerator
pedal. When the driver wishes to engage AutoStick ,
simply move the shift lever to the left or right (D-/D+)
position while in DRIVE. Hold the shift lever to the right for at least one second to
disengage AutoStick. The transmission will now oper-
ate automatically; shifting between the five available
gears.
General Information
•
You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to first
gear when coming to a stop. Tapping the shift lever to
the D+ position (at a stop) will allow starting in second
gear. After starting, the driver should continue to
manually upshift (D+) as the vehicle is accelerated.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when AutoStick
is en-
gaged.

STARTING AND OPERATING 247

The Anti-Lock Brake System pump motor runs during
the self-test at 12 mph (20 km/h) and during an ABS stop.
The pump motor makes a low humming noise during
operation, which is normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition
of the vehicle brakes and tires or the traction
afforded.(Continued)
WARNING! (Continued)
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
CAUTION!
The Anti-Lock Brake System is subject to possible
detrimental effects of electronic interference caused
by improperly installed after-market radios or tele-
phones.

STARTING AND OPERATING 253

NOTE:During severe braking conditions, a pulsing
sensation may occur and a clicking noise will be heard.
This is normal, indicating that the Anti-Lock Brake
System is functioning.
WARNING!
To use your brakes and accelerator more safely,
follow these tips:
•Do not “ride” the brakes by resting your foot on
the pedal. This could overheat the brakes and
result in unpredictable braking action, longer
stopping distances, or brake damage.
•When descending mountains or hills, repeated
braking can cause brake fade with loss of braking
control. Avoid repeated heavy braking by down-
shifting the transmission or locking out overdrive
whenever possible.
(Continued)
WARNING! (Continued)
•Engines may idle at higher speeds during warm-
up, which could cause rear wheels to spin and
result in loss of vehicle control. Be especially
careful while driving on slippery roads, in close-
quarter maneuvering, parking or stopping.
•Do not drive too fast for road conditions, espe-
cially when roads are wet or slushy. A wedge of
water can build up between the tire tread and the
road. This hydroplaning action can cause loss of
traction, braking ability, and control.
•After going through deep water or a car wash,
brakes may become wet, resulting in decreased
performance and unpredictable braking action.
Dry the brakes by gentle, intermittent pedal action
while driving at very slow speeds.
254 STARTING AND OPERATING

stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
“ESP Partial Off” mode. Refer to “Electronic Stability
Program (ESP)” in this section for more information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive thebenefit of the system, you must apply
continuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a BAS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user’s safety or the safety of others.
256 STARTING AND OPERATING

Off” mode by pressing the “ESP OFF” switch. Once the
situation requiring ESP to be switched to the “ESP Partial
Off” mode is overcome, turn ESP back on by momen-
tarily pressing the “ESP OFF” switch. This may be done
while the vehicle is in motion.
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. 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
“Trailer Towing” in “Starting and Operating” for further
information. When TSC is functioning, the “ESP/TCS
Indicator Light” will flash, the engine power may bereduced 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” mode.
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.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator lamp for the ESP is
combined with the BAS indicator. The “ESP/
BAS Warning Light” and the “ESP/TCS Indi-
cator Light” in the instrument cluster both
come on when the ignition switch is turned to the ON
position. They should both go out with the engine
running.
260 STARTING AND OPERATING

If the “ESP/BAS Warning Light” comes on
continuously with the engine running, a mal-
function has been detected in either the ESP or
the BAS system, or both. If this light remains on
after several ignition switch cycles, and the vehicle has
been driven several miles at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.
NOTE:
•The “ESP/TCS Indicator Light” and the “ESP/BAS
Warning Light” will come on momentarilyeach time
the ignition switch is turned to the ON position.
•Each time the ignition switch is turned to the ON
position, the ESP System will be ON even if it was
turned off previously.
•The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
