2017 JEEP GRAND CHEROKEE light

When the parking brake is applied with the ignition switch
in the ON position, the “Brake” Warning Light in the
instrument cluster will illuminate.
NOTE:
•When the parking brake is applied and the transmission
is placed in gear, the “Brake” Warning Light will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.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 movement and
possible injury or damage.
• When leaving the vehicle, always remove the key fob
from the ignition 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 gear
selector.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, remove
the key fob from the vehicle and lock the vehicle.
• Do not leave the key fob in or near the vehicle or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.

WARNING!(Continued)
•Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake” Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.

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, and
turn the ignition OFF. When the ignition is in the
OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the 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

light on the switch indicates when ECO mode is disabled
(for regular models) or a blue light when enabled (for SRT
models).
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 conserva-
tive. •
Vehicles with Quadra-Lift air suspension will operate in
Aero mode over a broader speed range. Refer to the
section on Quadra-Lift for further information.
• In SRT models, the transmission will launch (from a
stop) in second gear, and the torque converter clutch
may engage at lower engine speeds and remain on
longer.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation — Summit And SRT
Models Only
Your vehicle is equipped with an Active Noise Cancellation
System. This system uses four microphones embedded in
the headliner to detect undesirable exhaust noise, which
sometimes occurs when operating in ECO mode. An
onboard frequency generator creates counteracting sound
waves through the audio system to help keep the vehicle
quiet.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To

When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer toAutoStick in this section for further information)
to select a lower gear. Under these conditions, using a
lower gear will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE posi-
tion) enables full manual control of transmission shifting
(also known as AutoStick mode; refer to “AutoStick” in this
section for further information). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the transmission
gear, and will display the current gear in the instrument
cluster.Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal 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 engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.

the parking brake. The NEUTRAL (N) position disen-
gages both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:Refer to “Selec-Terrain – If Equipped” for further
information on the various positions and their intended
usages.
Shifting Procedures
4WDHITo4WDLOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,

information.
• Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The
preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph
(5 km/h), the transfer case will not allow the shift.

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features two torque
transfer couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the Quadra-
Trac II transfer case. The optional ELSD axle is fully
automatic and requires no driver input to operate. Under normal driving conditions, the unit functions as a standard
axle, balancing torque evenly between left and right
wheels. With a traction difference between left and right
wheels, the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque will
automatically transfer from the wheel that has less traction,
to the wheel that has traction. While the transfer case and
axle coupling differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shifting informa-
tion, preceding this section, for shifting this system.
QUADRA-LIFT — IF EQUIPPED
Description
The Quadra-Lift air suspension system provides full time
load leveling capability along with the benefit of vehicle
height adjustment by the push of a button. The vehicle will
automatically raise and lower the ride height to adapt to
the appropriate driving conditions. At higher speeds, the
vehicle will lower to an aerodynamic ride height and when
operating in off-road modes, the vehicle will raise the ride
height accordingly. The buttons near the terrain switch in
the center console area can be used to set preferred ride
height to match the appropriate conditions.
