2014 JEEP GRAND CHEROKEE ECO mode

Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “eco” switch in the center stack of the
instrument panel and a amber light will indicate the ECO
mode is engaged.When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•
The transmission will upshift sooner and downshift
later.
• The overall driving performance will be more conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
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.

Eight–Speed Automatic Transmission
Your vehicle is equipped with a state of the art, fuel
efficient eight-speed transmission. The electronic shift
lever in this vehicle does not slide like a conventional
shifter. Instead, the shift lever is spring loaded and moves
forward and rearward, always returning to the center
position after each gear is selected. The transmission gear
(PRND) is displayed both on the shift lever and in the
Electronic Vehicle Information Center (EVIC). To select a
gear range, press the lock button on the shift lever and
move the lever rearward or forward. You must press the
brake pedal to shift the transmission out of PARK, or to
shift from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). To shift past multiple gear ranges at once (such as
PARK to DRIVE), move the lever past the first (or second)
detent. Select the DRIVE range for normal driving.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
shifting between these gears.
The transmission shift lever provides PARK, REVERSE,
NEUTRAL, 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 shift paddles mounted on the steering
wheel. Pressing the shift paddles (-/+) while in the
404 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

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.

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

STARTING AND OPERATING 413

Selec-Terrain™ consists of the following positions:
•Snow – Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may
use second gear (rather than first gear) during launches, to minimize wheel slippage. If equipped
with air suspension, the level will change to Normal
Ride Height (NRH) if the transfer case is in high range.
The level will change to Off-Road 1 if the transfer case
is in Low range.
• Auto – Fully automatic full time four-wheel drive
operation can be used on and off road. Balances
traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles. If equipped with air suspension, the
level will change to NRH.
• Sand – Off road calibration for use on low traction
surfaces such as sand or wet grass. Driveline is maxi-
mized for traction. Some binding may be felt on less
forgiving surfaces. The electronic brake controls are set
to limit traction control management of throttle and
wheel spin. If equipped with air suspension, the level
will change to Off-Road 1.
