2011 JEEP GRAND CHEROKEE transmission

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the key fob in
the ignition switch. A child could operate power
windows, other controls, or move the vehicle.
Automatic Transmission
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
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.
Using Fob With Integrated Key (Tip Start)
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.

position (OFF position for Keyless Enter-N-Go).
Normal Starting
Using the ENGINE START/STOP Button
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
To start the engine, the transmission must be in PARK or
NEUTRAL. Press and hold the brake pedal while press-
ing the ENGINE START/STOP button once. The system
takes over and attempts to start the vehicle. If the vehicle
fails to start, the starter will disengage automatically after
10 seconds. If you wish to stop the cranking of the engine
prior to the engine starting, press the button again.
To Turn Off the Engine Using ENGINE
START/STOP Button
1. Place the shift lever in PARK, then press and release
the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the shift lever is not in PARK, the ENGINE START/
STOP button must be held for two seconds and vehicle
speed must be above 5 mph (8 km/h) before the engine
will shut off. The ignition switch position will remain in
the ACC position until the shift lever is in PARK and the
button is pressed twice to the OFF position. If the shift
lever is not in PARK and the ENGINE START/STOP
button is pressed once, the EVIC (if equipped) will
display a “Vehicle Not In Park” message and the engine
will remain running. Never leave a vehicle out of the
PARK position, or it could roll.

STARTING AND OPERATING 345

NOTE:If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after
30 minutes of inactivity and the ignition will switch to the
OFF position.
Keyless Enter-N-Go Functions – With Driver ’s
Foot OFF the Brake Pedal
(In PARK or NEUTRAL Position)
The Keyless Enter-N-Go feature operates similar to an
ignition switch. It has four positions, OFF, ACC, RUN
and START. To change the ignition switch positions
without starting the vehicle and use the accessories
follow these steps.
•Starting with the ignition switch in the OFF position:
•Press the ENGINE START/STOP button once to
change the ignition switch to the ACC position (EVIC
displays “IGNITION MODE ACCESSORY”),
•Press the ENGINE START/STOP button a second time
to change the ignition switch to the RUN position
(EVIC displays “IGNITION MODE RUN”),
•Press the ENGINE START/STOP button a third time
to return the ignition switch to the OFF position (EVIC
displays “IGNITION MODE OFF”).
Extreme Cold Weather (Below –20°F or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
346 STARTING AND OPERATING

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

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to the ON or
START position (engine running or not) and the brake
pedal must be pressed.
Five-Speed Automatic Transmission
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles/kilometers.
Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine, be sure to turn the
ignition switch to the LOCK position before restarting.
Transmission gear engagement may be delayed after
restarting the engine if the ignition switch is not turned to
the LOCK position first.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position.
350 STARTING AND OPERATING

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.

STARTING AND OPERATING 351

Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever left (-) or right (+) when the
shift lever is in the DRIVE position, allowing you to limit
the highest available gear. For example, if the driver
shifts the transmission into ERS 3 (third gear), the trans-
mission will never shift above third gear, but can shift
down to 2 (second) or 1 (first), when needed.
NOTE:
•If you pull and hold (not tap) the shift lever to the left
(-), the transmission will downshift to the lowest gear
that can be attained without overrevving the engine.
The display will show the gear the vehicle is in and
will limit the top gear to the one displayed.
•If you push and hold (not tap) the shift lever to the
right (+), the transmission will exit the gear limiting
mode and shift to the appropriate gear. The display
will readD. 3.6L Engine
When in the DRIVE position, the first tap to the left (-)
will shift down one gear and will display that gear. For
example, if you are in DRIVE and are in fifth gear, when
you tap the shift lever one time to the left (-), the
transmission will downshift to fourth gear and the dis-
play will show 4. Another tap to the left (-) will shift the
transmission into third gear.
5.7L Engine
On vehicles equipped with the 5.7L engine, use of ERS (or
TOW/HAUL mode) also enables an additional under-
drive gear which is not normally used during through-
gear accelerations. This additional gear improves vehicle
performance and cooling capability when towing a trailer
on certain grades. ERS 1, 2, and 3 are underdrive gears;
ERS 4 is direct drive. ERS 5 (Overdrive) is the same as the
normal 4th gear. When in the DRIVE position in first
through fourth gear, the first tap to the left (-) will display
352 STARTING AND OPERATING

the ERS designation for the current gear (the transmis-
sion will not downshift). For example, if you are in
DRIVE and are in third (direct) gear, when you tap the
shift lever one time to the left (-), the display will show 4
(ERS 4 is direct gear). Another tap to the left (-) will shift
the transmission down to ERS 3 (the added underdrive
gear). When in the DRIVE position in fifth gear, the first
tap to the left (-) will downshift the transmission and
display 5 (ERS 5 is the same as normal fourth gear).
Another tap to the left (-) will shift the transmission
down to ERS 4 (direct gear).
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), move the shift lever to the
left “D(-)” and hold it there. The transmission will shift to
the range from which the vehicle can best be slowed
down.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear for 3.6L engine, fourth
and fifth gears for 5.7L engine). The transmission will
automatically shift to Overdrive, if the following condi-
tions are present:
