2014 JEEP GRAND CHEROKEE ECU

WARNING!
In a collision, a loose cargo cover in the vehicle could
cause injury. It could fly around in a sudden stop and
strike someone in the vehicle. Do not store the cargo
cover on the cargo floor or in the passenger compart-
ment. Remove the cover from the vehicle when taken
from its mounting. Do not store it in the vehicle.
Rear Cargo Tie-Downs
The rear cargo tie-downs, located on the cargo area floor,
should be used to safely secure loads when the vehicle is
moving.

•If (or any metallic object) is placed over the satellite
radio antenna (if equipped), you may experience in-
terruption of satellite radio reception. For improved
satellite radio reception, avoid placing the rear cross-
bar over the satellite radio antenna.
CAUTION!
• To prevent damage to the roof of your vehicle, do
not carry any loads on the roof rack without the
crossbars installed. The load should be secured and
placed on top of the crossbars, not directly on the
roof. If it is necessary to place the load on the roof,
place a blanket or some other protection between
the load and the roof surface.
(Continued)
CAUTION! (Continued)
•To avoid damage to the roof rack and vehicle, do
not exceed the maximum roof rack load capacity of
150 lb (68 kg). Always distribute heavy loads as
evenly as possible and secure the load appropri-
ately.
• Long loads which extend over the windshield, such
as wood panels or surfboards, or loads with large
frontal area should be secured to both the front and
rear of the vehicle.
• Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof
rack. Wind forces, due to natural causes or nearby
truck traffic, can add sudden upward lift to a load.
This is especially true on large flat loads and may
result in damage to the cargo or your vehicle.

vehicle. Improperly secured loads can fly off the
vehicle, particularly at high speeds, resulting in per-
sonal injury or property damage. Follow the roof rack
cautions when carrying cargo on your roof rack.

19. Vehicle Security LightThis light will flash rapidly for approximately
15 seconds when the vehicle theft alarm is
arming. The light will flash at a slower speed
continuously after the alarm is set. The security
light will also come on for about three seconds when the
ignition is first turned on.
20. Electronic Stability Control (ESC) OFF Indicator
Light — If Equipped
This light indicates the Electronic Stability Con-
trol (ESC) is off.
21. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON/RUN position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on
momentarily each time the ignition switch is turned
to ON/RUN.
• Each time the ignition is turned to ON/RUN, the
ESC system will be ON, even if it was turned off
previously.

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 OFF position, the transmis-
sion is locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always make sure the
ignition switch is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.

WARNING! (Continued)
•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 transmission gear selector.
• 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.

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.

•Install on Rear Tires Only
• Due to limited clearance, the Security Chain Company
(SCC) Super Z6 low profile traction device or equiva-
lent is recommended on P265/60R18 or 265/50R20
tires.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance be-
tween tires and other suspension components, it is
important that only traction devices in good condi-
tion are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise
occurs that could indicate device breakage. Remove
the damaged parts of the device before further use.
• Install device as tightly as possible and then re-
tighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for a prolonged period on dry pave-
ment.
