2014 JEEP GRAND CHEROKEE Owners Manual

WARNING!(Continued)
transmission is locked in PARK, securing the ve-
hicle 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. Allowing children to
be in a vehicle unattended is dangerous for a num-
ber of reasons. A child or others could be seriously
or fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission shifter. Do not leave the Key Fob in or near
the vehicle (or in a location accessible to children),
and do not leave the ignition (in a vehicle equipped
with Keyless Enter-N-Go™) in the ACC or ON/RUN
position. A child could operate power windows,
other controls, or move the vehicle.

CAUTION!(Continued)
•Before moving the shift lever out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the shift lever could
result.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
• When shifting into PARK, press the lock button on the
shift lever and push the lever all the way forward until
it stops. When released, the lever will return to the
center position.
• With brake pedal released, look at the transmission
gear position display and verify that it indicates the
PARK position. REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
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.
408 STARTING AND OPERATING

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.
DRIVE (D)
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 all forward gears. The
DRIVE position provides optimum driving characteris-
tics 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 Paddle Shift
switches (refer to
Paddle Shift Mode 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.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
SPORT (S)
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. To
5

switch between DRIVE and SPORT modes, tap the shift
lever rearward. SPORT mode is only accessible from
DRIVE.
NOTE:When Sport Mode is enabled, the vehicle’s air
suspension system will operate in “Aero” Mode. Please
refer to “Quadra Lift” within this section 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 may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after en-
gine shutdown, perform this procedure only in a desired
location (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Turn the ignition switch to the OFF position. On vehicles with Keyless Enter-N-Go™, press and hold
the ignition switch until the engine turns OFF.
410 STARTING AND OPERATING

4. Wait approximately 30 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.
Paddle Shift Mode
Paddle Shift mode is a driver-interactive transmission
feature providing manual shift control, giving you more control of the vehicle. Paddle Shift allows you to maxi-
mize 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 transmission is in DRIVE or SPORT mode, it
will operate automatically, shifting between the eight
available gears. To engage Paddle Shift mode, simply tap
one of the steering wheel-mounted shift paddles (+/-)
while in DRIVE or SPORT mode. Tapping (-) to enter
Paddle Shift mode will downshift the transmission to the
next lower gear, while using (+) to enter Paddle Shift
mode will retain the current gear. When Paddle Shift
mode is active, the current transmission gear is displayed
in the instrument cluster.
5
STARTING AND OPERATING 411

In Paddle Shift mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below.
•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, from a stop, in first or second gear
(or third gear, in 4LO range, Snow mode, or Sand
mode). Tapping (+) at a stop will allow starting in
second gear. Starting out in second gear is helpful in
snowy or icy conditions. •
If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Holding the (-) paddle depressed will progressively
downshift the transmission to the lowest gear possible
at the current speed.
• Transmission shifting will be more noticeable when
Paddle Shift mode is enabled.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
NOTE: When Selec-Speed or Hill Descent Control is
enabled, Paddle Shift mode is not active. Pressing the
(+/-) shift paddles in Selec-Speed or Hill Descent Control
simply limits the highest allowed gear. Shifts below and
up to that gear will occur automatically.
412 STARTING AND OPERATING

To disengage Paddle Shift mode, press and hold the (+)
shift paddle untilDorS is once again displayed in the
instrument cluster. You can shift in or out of Paddle Shift
mode 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.
FOUR-WHEEL DRIVE OPERATION
Quadra-Trac I® Operating Instructions/
Precautions — If Equipped
The Quadra-Trac I® is a single-speed (HI range only)
transfer case, which provides convenient full-time four-
wheel drive. No driver interaction is required. The Brake Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:
The Quadra-Trac I® system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Oper-
ating” for further information.
Quadra-Trac II® Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II® transfer case is fully automatic in
the normal driving 4WD AUTO mode. The Quadra-Trac
II® transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
5
STARTING AND OPERATING 413

This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive
shafts from the powertrain and will allow the vehicle
to move regardless of the transmission position. The
parking brake should always be applied when the
driver is not in the vehicle.
