2011 JEEP GRAND CHEROKEE stop start

If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle.
This type of start can be dangerous if done improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.
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 Weatherproce-
dures, it may be flooded. To clear any excess fuel, press
and hold the brake pedal, push the accelerator pedal all
the way to the floor and hold it, then 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.

AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing 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 from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on 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 when your foot is
firmly on the brake pedal.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to turning the ignition switch to the LOCK position.
The key fob can only be removed from the ignition switch
when the ignition switch is in the LOCK position. Once
the key fob is removed, the shift lever is locked in PARK.

STARTING AND OPERATING 349

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.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on 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 when
your right foot is firmly on the brake pedal.
REVERSE
This range is for moving the vehicle backward. Use only
after the vehicle has come to a complete stop.
NEUTRAL
This range is used when vehicle is standing for pro-
longed periods with engine running. Engine may be
started in this range. Set the parking brake and shift the
transmission into PARK if you must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with the shift lever in NEUTRAL can result
in 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
This range should be selected only when the vehicle is at
a complete stop and the brakes are firmly applied. The
transmission automatically upshifts through fifth gear.
The DRIVE position provides optimum driving charac-
teristics under all normal operating conditions.
5
STARTING AND OPERATING 351

operating in TOW/HAUL mode, the transmission will
shift into direct gear and Overdrive will be enabled
under steady cruise conditions.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restoresnormal operation. If the TOW/HAUL mode is desired,
the switch must be pressed each time the engine is
started.
In high ambient temperatures with sustained high engine
speed and load, an upshift, followed shortly thereafter by
a downshift, may occur. The “TOW/HAUL Indicator
Light” will turn off. This is a normal part of the overheat
protection strategy when operating in the TOW/HAUL
mode.
Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the Transmission Limp Home
Mode will be engaged. In this mode, the transmission
will remain in the current gear (3.6L engine) or in direct
gear (5.7L engine) until the vehicle is brought to a stop.
TOW/HAUL Switch

STARTING AND OPERATING 355

To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever into the PARK position.
3. Turn the engine off, and be sure to turn the ignition
switch to the LOCK position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever to the desired gear range.
If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Only second gear (3.6L engine) or third gear (5.7L
engine) will be available in the DRIVE position. Have the
transmission checked at your authorized dealer as soon
as possible.Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally, at a calibrated speed, at light throttle. It engages at
higher speeds under heavier acceleration. This may re-
sult in a slightly different feeling or response during
normal operation in high gear. When the vehicle speed
drops below a calibrated speed, or during acceleration,
the clutch automatically and smoothly disengages.
NOTE:
•The torque converter clutch may not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because the engine speed is higher when the torque
converter clutch is not engaged, it may seem as if the
transmission is not shifting into Overdrive when cold.
This is normal. Manually shifting (using the ERS shift
control) between 4 (direct gear) and 5/D (Overdrive
356 STARTING AND OPERATING

Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions
For 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 “Start-
ing and Operating” for further information on the vari-
ous 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 Operating” for further information.

STARTING AND OPERATING 359

4WD LOW to 4WD HI
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 flash and go out when the shift is complete.
NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“For 4x4 High Slow Below 3 MPH or 5 KPH Put Trans
in N Press 4 Low” message will flash from the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further
information.
•Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty mayoccur due to the mating clutch teeth not being prop-
erly 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.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position, engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a pen,
etc.) for four seconds until the LED light by the switch
starts to blink indicating shift in progress. The light will
stop blinking (stay on solid) when the NEUTRAL shift is
complete. A “To Tow Vehicle Safely, Read Neutral Shift
Procedure in Owners Manual” message will display on5
STARTING AND OPERATING 361

Standing Water
Avoid driving in standing water deeper than 20 inches
(51 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 20 inches (51 cm) of
water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to pre-
vent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to alower gear than necessary to maintain forward motion.
Over-revving the engine can spin the wheels and traction
will be lost.
Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to a stop
and immediately apply the brakes. Restart the engine,
and shift into REVERSE. Back slowly down the hill,
allowing the compression braking of the engine to help5
