2014 JEEP GRAND CHEROKEE brake

Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placing
the transmission in PARK. This system also locks the
transmission in PARK whenever the ignition switch is in
the OFF position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the engine must be running and the brake
pedal must be pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE or REVERSE
when the vehicle is stopped or moving at low speeds.
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 green light will indicate the ECO
mode is engaged.
Fuel Economy Mode Switch
398 STARTING AND OPERATING

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 transmission will launch (from a stop) in second
gear.
• The torque converter clutch may engage at lower
engine speeds and remain on longer.
• The engine idle speed will be lower.
• 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: ECO mode is only available in AUTO mode.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 also 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.

STARTING AND OPERATING 399

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 theDRIVE or SPORT position will manually select the trans-
mission gear, and will display the current gear in the
instrument cluster. Refer to
Paddle Shift Modein this
section for further information.

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
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 (P)
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 shift the
transmission into PARK first, and then apply the parking
brake. When parking on a hill, apply the parking brake before
shifting the transmission to 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 in PARK. Make sure the transmission is
in PARK before leaving the vehicle.

STARTING AND OPERATING 401

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.
• 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 OFF position, the
transmission is locked in PARK, securing the ve-
hicle against unwanted movement.
(Continued)
WARNING! (Continued)
•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 number
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.

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 its
home position.
• With brake pedal released, look at the transmission
gear position display and verify that it indicates the
PARK position.

STARTING AND OPERATING 403

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.
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,

operation can be used on and off road. Balances traction
with seamless steering feel to provide improved han-
dling and acceleration over two-wheel drive vehicles.
The active suspension system will be in Touring Mode.
• Track –Track road calibration for use on high traction
surfaces. Driveline is maximized for traction. Some
binding may be felt on less forgiving surfaces. The
electronic brake controls are set to Partial OFF to limit
traction control management of throttle and wheel spin.
• The transmission will be in SPORT mode and pro-
vide a more aggressive shifting pattern. Refer to
“Paddle Shift Mode” in “Starting And Operating”
for further information.
• The customer has the option of going to FULL OFF
with no interaction from the ESC System. The active
suspension system will be in Full Firm mode.
• This feature will reset to AUTO on an ignition cycle. •
To w – Use this mode for towing. Vehicle suspension
will go to Firm mode. Trailer sway control is enabled
in the ESC system. The terrain switch will remain in
this position through an ignition cycle until the cus-
tomer cycles into another position.
Active Damping System
This vehicle is equipped with an electronic controlled
damping system. This system reduces body roll and pitch
in many driving situations including cornering, accelera-
tion and braking. There are 3 modes:
• Touring Mode (Available in terrain positions AUTO
and SNOW) — Used during highway speeds where a
touring suspension feel is desired.
• Firm Mode
(Available in terrain positions SPORT and
TOW) — Provides a firm suspension for better handling.
