2013 JEEP GRAND CHEROKEE light

Panel ModeAir comes from the outlets in the in-
strument panel. Each of these outlets
can be individually adjusted to direct
the flow of air. The air vanes of the center
outlets and outboard outlets can be moved up
and down or side to side to regulate airflow
direction. There is a shut off wheel located
below the air vanes to shut off or adjust the
amount of airflow from these outlets.
Bi-Level Mode
Air comes from the instrument panel
outlets, floor outlets and defrost outlets.
NOTE:
In many temperature positions, the Bi–Level
mode is designed to provide cooler air out of
the panel outlets and warmer air from the
floor outlets.
Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the
defrost and side window demister outlets.
Mix Mode
Air comes from the floor, defrost and
side window demist outlets. This mode
works best in cold or snowy conditions.
It allows you to stay comfortable while keeping
the windshield clear.
Defrost Mode
Air comes from the windshield and
side window demist outlets. Use De-
frost mode with maximum temperature
settings for best windshield and side window
defrosting. When the defrost mode is selected,
the blower will automatically default to medium-
high unless the blower is controlled manually.
NOTE:
While operating in the other modes, the
system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. Defrost mode must be manually se-
lected to clear the windshield and side
glass. Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When in A/C mode and
the ATC is set to a cool temperature, dehumidi-
fied air flows through the air outlets. If Economy
mode is desired, press the A/C button to turn off
the A/C mode in the ATC display and deactivate
the A/C system. Also, make sure to select only
Panel, Bi-Level or Floor modes.
NOTE:
•
If the system is in Mix, Floor or Defrost
Mode, the A/C can be turned off, but the
A/C system shall remain active to prevent
fogging of the windows.
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed.

Clearing A Flooded Engine (Using ENGINE
START/STOP Button)
If the engine fails to start after you have followed
the “Normal Starting” or “Extreme Cold Weather"
procedures, it may be flooded. To clear any
excess fuel:
1. Press and hold the brake pedal.
2. Press the accelerator pedal all the way to the
floor and hold it.
3. Press and release the ENGINE START/
STOP button once.
The starter motor will engage automatically, run
for 10 seconds, and then disengage. Once this
occurs, release the accelerator pedal and the
brake pedal, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure. Clearing A Flooded Engine
(Using Fob With Integrated Key)
If the engine fails to start after you have followed
the “Normal Starting” or “Extreme Cold Weather”
procedures, it may be flooded. To clear any
excess fuel:
1. Press the accelerator pedal all the way to the
floor and hold it.
2.
Turn the ignition switch to the START position
and release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
After StartingThe idle speed is controlled automatically and it
will decrease as the engine warms up.
Normal Starting – Diesel EngineObserve the following when the engine is oper-
ating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Low Oil Pressure Light is off.
Cold Weather Precautions
Operation in ambient temperature below
32°F (0°C) may require special considerations.
The following chart suggests these options.
*No. 1 Ultra Low Sulfur Diesel Fuel (ULSD)
should only be used where extended arctic
conditions (-10°F/-23°C) exist.
223

NOTE:
•Use of Climatized ULSD Diesel Fuel or
Number 1 ULSD Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized ULSD Diesel Fuel is a blend of
Number 2 ULSD and Number 1 ULSD
Diesel Fuels, which reduces the tempera-
ture at which wax crystals form in fuel.
NOTE:
This engine requires the use of “Ultra Low
Sulfur Diesel Fuel.” Use of incorrect fuel
could result in exhaust system damage. Re-
fer to “Fuel Requirements – Diesel Engine”
in “Starting and Operating” for further infor-
mation.
Battery Blanket Usage
A battery loses 60% of its cranking power as the
battery temperature decreases to 0°F (-18°C).
For the same decrease in temperature, the en-
gine requires twice as much power to crank at the
same RPM. The use of battery blankets will
greatly increase starting capability at low tem-
peratures. Suitable battery blankets are available
from your authorized MOPAR® dealer.
Engine Starting Procedure
WARNING!
NEVER pour fuel or other flammable liquid
into the air inlet opening in an attempt to start
the vehicle. This could result in a flash fire
causing serious personal injury.
1. The shift lever must be in the NEUTRAL or
PARK position before you can start the engine.
2. With your foot on the brake pedal, press the
ENGINE START/STOP button.
3. Watch the “Wait To Start Light” in the instru-
ment cluster. Refer to “Instrument Cluster” in
“Understanding Your Instrument Panel” for fur-
ther information. It may glow for up to three
seconds, depending on engine temperature.
4. When the “Wait To Start Light” goes out, the
engine will automatically start.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving. This
allows oil to circulate and lubricate the turbo-
charger. 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.
Engine Warm Up
Avoid full throttle operation when the engine is
cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow the
oil pressure to stabilize as the engine warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
If temperatures are below 32°F (0°C), operate
the engine at moderate speeds for five minutes
before full loads are applied.
224

REVERSE
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL
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 Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, and third
gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum
driving characteristics under all normal operat-
ing conditions. When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick® shift control
(refer to “AutoStick®” in this section) to select a
lower gear. Under these conditions, using a
lower gear will improve performance and ex-
tend transmission life by reducing excessive
shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
direct gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.
229

DRIVE
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first and second
gears, direct third gear and overdrive fourth and
fifth gears. The DRIVE position provides opti-
mum driving characteristics under all normal
operating conditions.
To access all six available gears, you must use
the Electronic Range Select (ERS) shift control
(refer to “Electronic Range Select (ERS) Opera-
tion” in this section).
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the Electronic Range Select
(ERS) shift control (refer to “Electronic Range
Select (ERS) Operation” in this section) to se-
lect a lower gear range. Under these conditions,
using a lower gear range will improve perfor-
mance and extend transmission life by reducing
excessive shifting and heat buildup.If the transmission temperature exceeds normal
operating limits, the powertrain controller will
modify the transmission shift schedule and ex-
pand the range of torque converter clutch en-
gagement. This is done to prevent transmission
damage due to overheating.
If the transmission becomes extremely hot or is
in danger of overheating, the “Transmission
Temperature Warning Light” may illuminate and
the transmission may operate differently until
the transmission cools down.
NOTE:
Use caution when operating a heavily
loaded vehicle at low speeds (such as tow-
ing a trailer up a steep grade, or in stop-
and-go traffic) during hot weather. In these
conditions, torque converter slip can im-
pose a significant additional heat load on
the cooling system. Downshifting the trans-
mission to the lowest possible gear (when
climbing a grade), or shifting to NEUTRAL
(when stopped in heavy traffic) can help to
reduce this excess heat generation.
During cold temperatures, transmission opera-
tion may be modified depending on engine andtransmission temperature as well as vehicle
speed. This feature improves warm up time of
the engine and transmission to achieve maxi-
mum efficiency. Engagement of both the torque
converter clutch and the top overdrive gear are
inhibited until the transmission fluid is warm
(refer to the “Note” under “Torque Converter
Clutch” in this section). During extremely cold
temperatures (-16°F [-27°C] or below), opera-
tion may briefly be limited to first and direct
gears only. Normal operation will resume once
the transmission temperature has risen to a
suitable level.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
direct gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.
234

Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fourth and fifth
gears). The transmission will automatically shift
into Overdrive if the following conditions are
present:
•the shift lever is in the DRIVE position,
• the transmission fluid has reached an ad-
equate temperature,
• the engine coolant has reached an adequate
temperature,
• vehicle speed is sufficiently high,
• the driver is not heavily pressing the accel-
erator, and
•
the TOW/HAUL switch has not been activated.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent trans-
mission shifting occurs, press the TOW/HAUL
switch to activate TOW/HAUL mode. This will
improve performance and reduce the potential
for transmission overheating or failure due to
excessive shifting. When operating in TOW/ HAUL mode, transmission upshifts are delayed,
and the transmission will automatically down-
shift (for engine braking) during steady braking
maneuvers.
The “TOW/HAUL Indicator Light” will illuminate
in the instrument cluster to indicate that TOW/
HAUL mode has been activated. Pressing the
switch a second time restores normal operation.
Normal operation is always the default at en-
gine start-up. If TOW/HAUL mode is desired,
the switch must be pressed each time the
engine is started.
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically at calibrated
speeds. This may result in a slightly different
feeling or response during normal operation in
the upper gears. When the vehicle speed drops
or during some accelerations, the clutch auto-
matically disengages.
NOTE:
•
The torque converter clutch will not en-
gage, and the transmission will not shift
into the top overdrive gear, until the trans-
mission fluid and engine coolant are
warm [usually after 1 to 3 miles (2 to 5 km)
of driving]. Because top gear is disabled,
and engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting properly when cold. This is nor-
mal. Using the Electronic Range Select
(ERS) shift control, when the transmis-
sion is sufficiently warm, will demon-
strate that the transmission is able to shift
into and out of Overdrive.

Shift PositionsFor additional information on the appropriate
use of each transfer case mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.
NOTE:
Refer to “Selec-Terrain® – If Equipped” in
“Starting and Operating” for further infor-
mation on the various positions and their
intended usages.
NEUTRAL
This range disengages both the front and rear
driveshafts from the powertrain. It is to be used
for flat towing behind another vehicle. Refer to
“Recreational Towing” in “Starting and Operat-
ing” for further information.4WD LOW
This range is for low speed four-wheel drive. It
locks the front and rear driveshafts together and
forces the front and rear wheels to rotate at the
same speed. It provides additional traction and
maximum pulling power for loose, slippery 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
4WD HI To 4WD LOW
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, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster will
begin to flash and remain on solid when the shift
is complete.
NOTE:
If shift conditions/interlocks are not met, or
a transfer case motor temperature protec-
tion condition exists, a “For 4x4 Low Slow
Below 3 MPH or 5 KPH Put Trans in N Press
