2013 JEEP GRAND CHEROKEE ECU

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 protec-
tion between the load and the roof surface.
• To avoid damage to the roof rack and
vehicle, do not exceed the maximum roof
rack load capacity of 150 lb (68 kg). Al-
ways distribute heavy loads as evenly as
possible and secure the load appropriately.
• Long loads which extend over the wind-
shield, such as wood panels or surfboards,
or loads with large frontal area should be
secured to both the front and rear of the
vehicle.

CAUTION!(Continued)
•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.
WARNING!
Cargo must be securely tied before driving
your vehicle. Improperly secured loads can
fly off the vehicle, particularly at high speeds,
resulting in personal injury or property dam-
age. Follow the roof rack cautions when
carrying cargo on your roof rack.

proximately 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.
25. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily. The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It
should not be allowed to exceed the upper limits
of the normal operating range.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H” and you hear continuous chimes,
turn the engine off immediately and call an
authorized dealer for service.

Engine Idling – In Cold Weather
Avoid prolonged idling in ambient temperatures
below 0°F (-18°C). Long periods of idling may
be harmful to your engine because combustion
chamber temperatures can drop so low that the
fuel may not burn completely. Incomplete com-
bustion allows carbon and varnish to form on
piston rings and injector nozzles. Also, the
unburned fuel can enter the crankcase, diluting
the oil and causing rapid wear to the engine.
Stopping The Engine
Before turning off your turbo diesel engine,
always allow the engine to return to normal idle
speed and run for several seconds. This as-
sures proper lubrication of the turbocharger.
This is particularly necessary after any period of
hard driving.
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe-
cially important for turbocharged, charge air
cooled engines.AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
•
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
WARNING!
• Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a ve-
hicle 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 posi-
tion, the shift lever is locked in PARK,
securing the vehicle against unwanted
movement.
• 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 reverse.
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.

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 unat-
tended is dangerous for a number of rea-
sons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the shift lever.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), and do not leave Keyless Enter-N-
Go™ in the ACC or ON/RUN position. A
child could operate power windows, other
controls, or move the vehicle.
CAUTION!
• Before moving the shift lever out of PARK,
you must turn the ignition switch from the
OFF position to the ON/RUN position, and
also press the brake pedal. Otherwise,
damage to the shift lever could result.
• DO NOT race the engine when shifting
from PARK or NEUTRAL into another gear
range, as this can damage the drivetrain.
The following indicators should be used to
ensure that you have engaged the shift lever
into the PARK position:
• When shifting into PARK, firmly move the
shift lever all the way forward and to the left
until it stops and is fully seated.
• Look at the shift lever position display and
verify that it indicates the PARK position.
• With brake pedal released, verify that the
shift lever will not move out of PARK.

In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the transmission
will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur. If the transmission cannot be
reset, authorized dealer service is required.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the shift lever is in
the DRIVE position, the transmission will oper-
ate automatically, shifting between all available
gears. Tapping the shift lever to the left (-) will
downshift the transmission, activate ERS mode,
display the current gear in the instrument clus-
ter, and maintain that gear as the top available
gear. Once in ERS mode, tapping the shift lever
to the left (-) or right (+) will change the top
available gears.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.

•If there is a need to restart the engine, be
sure to cycle the ignition to the OFF
position before restarting. Transmission
gear engagement may be delayed after
restarting the engine if the key is not
cycled to the OFF position first.
PARK
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 place
the shift lever in PARK first, and then apply the
parking brake.
When parking on a hill, apply the parking brake
before placing the shift lever in PARK, otherwise
the load on the transmission locking mecha-
nism may make it difficult to move the shift lever
out of PARK. As an added precaution, 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 substi-
tute for the parking brake. Always apply
the parking brake fully when parked to
guard against vehicle movement and pos-
sible injury or damage.
• Your vehicle could move and injure you
and others if it is not completely in PARK.
Check by trying to move the shift lever out
of PARK with the brake pedal released.
Make sure the transmission is in PARK
before leaving the vehicle.
• 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 reverse.
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.

The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gears normally.
Use of ERS (or TOW/HAUL mode) also enables
an additional underdrive gear which is not nor-
mally used during through-gear accelerations.
This additional gear can improve vehicle perfor-
mance and cooling capability when towing a
trailer on certain grades. In ERS mode, gears 1
though 3 are underdrive gears, and ERS 4 is
direct drive. ERS 5 and 6 (Overdrive gears ) are
the same as the normal fourth and fifth gears.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the shift lever is in the
DRIVE position, the transmission will operate
automatically, shifting between all available
gears. Tapping the shift lever to the left (-) will
activate ERS mode, display the current gear in
the instrument cluster, and maintain that gear as
the top available gear. Once in ERS mode, tap-
ping the shift lever to the left (-) or right (+) will
change the top available gear.
The instrument cluster display will show the
requested top gear limit, however the transmis-
sion will not downshift to the requested gear if
doing so would overspeed the engine. The
transmission will downshift once the vehicle
speed has slowed sufficiently.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
