2013 JEEP GRAND CHEROKEE transmission

Five-Speed Automatic Transmission
The shift lever position display (located in the instrument
cluster) indicates the transmission gear range. You must
press the brake pedal to move the shift lever out of PARK
(refer to “Brake/Transmission Shift Interlock System” in
this section). To drive, move the shift lever from PARK or
NEUTRAL to the DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when 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 transmission shift lever has only Park, Reverse,
Neutral, and Drive shift positions.
Manual shifts can be made using the AutoStick
shift
control (refer to “AutoStick” in this section). Moving the
shift lever left or right (-/+) 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 5,4, 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
If there is a need to restart the engine, be sure to cycle the
ignition to the LOCK/OFF position before restarting.
Transmission gear engagement may be delayed after
restarting the engine if the key is not cycled to the
LOCK/OFF position first.
456 STARTING AND OPERATING

NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold.
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 PARK 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
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever rearward (with the brake pedal
released), after you have placed it in PARK. Make
sure the transmission is in PARK before leaving
the vehicle.

WARNING!(Continued)
•It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.
(Continued)
WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK
turn the engine OFF, and remove the key fob. When
the ignition is in the LOCK/OFF position, the shift
lever is locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always remove the key
fob and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
(Continued)
458 STARTING AND OPERATING

•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 the engine running. The engine may be
started in this range. Apply the parking brake and shift
the transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
460 STARTING AND OPERATING

DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
and third gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the “AutoStick” shift
control (refer to “AutoStick” in this section) to select a
lower gear. Under these conditions, using a lower gear
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
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-Track” 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)5
STARTING AND OPERATING 461

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 ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation. NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized
dealer service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear). The transmission will
automatically shift into Overdrive if the following con-
ditions are present:
• the shift lever is in the DRIVE position,
• vehicle speed is sufficiently high, and
• the driver is not heavily pressing the accelerator.
462 STARTING AND OPERATING

When to Use TOW Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, select TOW mode, using the rotary switch on the
center console. Selecting TOW mode will improve per-
formance and reduce the potential for transmission over-
heating or failure due to excessive shifting. Refer to
“Selec-Track – If Equipped” in “Starting And Operating”
for further information.
AUTOSTICK
AutoStickis a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. 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 AutoStick mode will
downshift the transmission to the next lower gear, while
using (+) to enter AutoStick mode will retain the current
gear. When AutoStick is 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,
5
STARTING AND OPERATING 463

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 AutoStick mode, the transmission will
automatically shift up when maximum engine speed is
reached. If, however, AutoStick is engaged while in
SPORT or TRACK 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. •
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 AutoStick is
engaged.
• Transmission shifting will be more noticeable when
AutoStick is engaged.
To disengage AutoStick mode, 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 AutoStick mode at any time
without taking your foot off the accelerator pedal.
