2012 JEEP GRAND CHEROKEE stop start

CAUTION! (Continued)
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
•Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE:You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing on
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or some-
thing. Only shift into gear when the engine is
idling normally and when your foot is firmly
pressing on the brake pedal.

vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
The shift lever (with AutoStickshift paddles mounted
on the steering wheel) provides PARK, REVERSE, NEU-
TRAL, DRIVE, and SPORT shift positions. Once in the
DRIVE range, tapping the shift lever rearward will toggle
between SPORT mode and DRIVE mode. You do not
need to press the shift lever button when toggling
between DRIVE and SPORT modes.
Manual shifts can be made using the AutoStickshift
control (refer to “AutoStick” in this section). Pressing
the shift paddles (-/+) while in the DRIVE position, or
tapping one of the steering wheel-mounted shift paddles(-/+), will manually select the transmission gear, and will
display the current gear in the instrument cluster as 4, 3,
2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the

CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, move the shift lever all the
way forward and to the left until it stops and is fully
seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
•With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with engine running. The engine may be started
in this range. Set the parking brake and shift the trans-
mission into PARK if you must leave the vehicle.
386 STARTING AND OPERATING

SPORT
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.
SPORT mode is activated using the rotary switch on the
center console. Refer to “Selec-Terrain” in “Starting And
Operating” for further information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. The Malfunction Indicator Light (MIL)may be illuminated. Limp Home Mode allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
388 STARTING AND OPERATING

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 shift lever is in the DRIVE position, the
transmission will operate automatically, shifting between
the five available gears. To engage AutoStick, simply tap
the shift lever to the right or left (+/-) while in the DRIVE
position, or tap one of the steering wheel-mounted shift
paddles (+/-). Tapping (-) to enter AutoStickmode will
downshift the transmission to the next lower gear, while
using (+) to enter AutoStickmode will retain the current
gear. When AutoStickis active, the current transmission
gear is displayed in the instrument cluster. In AutoStick
mode, the transmission will shift up or down when (+/-)
is manually selected by the driver (using the shift lever,or the shift paddles), unless an engine lugging or over-
speed condition would result. It will remain in the
selected gear until another upshift or downshift is cho-
sen, except as described below.
•Normally, in AutoStickmode, the transmission will
automatically shift up when maximum engine speed is
reached. If, however, AutoStickis engaged while in
SPORT mode, the transmission will remain in the
selected gear even when maximum engine speed is
reached. The transmission will upshift only when
commanded by the driver.
•The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
•The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
390 STARTING AND OPERATING

•You can start out in first or second gear. Tapping (+) (at
a stop) will allow starting in second gear. Starting out
in second gear is helpful in snowy or icy conditions.
•The system will ignore attempts to upshift at too low
of a vehicle speed.
•Avoid using speed control when AutoStickis en-
gaged.
•Transmission shifting will be more noticeable when
AutoStickis engaged.
To disengage AutoStickmode, hold the shift lever to the
right or press and hold the (+) shift paddle until “D” is
once again displayed in the instrument cluster. You can
shift in or out of the AutoStickmode at any time
without taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.

STARTING AND OPERATING 391

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
396 STARTING AND OPERATING

Differential (BLD), 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 ESC system is in the “Partial Off” mode.
Refer to “Electronic Stability Control (ESC)” in this
section for further 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 applycontinuousbrak-
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 BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
BAS cannot prevent collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
