2016 JEEP GRAND CHEROKEE engine

WARNING!(Continued)
•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 improperly. Refer
to “Jump-Starting” in “What To Do In Emergen-
cies” for further information.

dures, 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. Push 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
WARNING!
•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 re-
verse. 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.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
(Continued)
WARNING! (Continued)
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,
and make sure the keyless ignition node is in the
OFFmode. Remove the Key Fob from the vehicle,
and lock the vehicle. When the keyless ignition is
in the OFF mode, the transmission is locked in
PARK, securing the vehicle against unwanted
movement.
• 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.

WARNING!(Continued)
•When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, re-
move the key fob from the vehicle and lock the
vehicle.
• Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition in the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
• Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
(Continued)
CAUTION! (Continued)
•Do not shift between PARK, REVERSE, NEU-
TRAL, 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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placing
the transmission in PARK. This system also locks the
transmission in PARK whenever the ignition switch is in
the OFF position.

STARTING AND OPERATING 469

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the gear selector in
PARK unless the brakes are applied. To shift the trans-
mission out of PARK, the engine must be running and the
brake pedal must be pressed. The brake pedal must also
be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “ECO” switch in the center stack of the
instrument panel to activate or disable ECO mode. An
amber light indicates when ECO mode is engaged.When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•
The transmission will upshift sooner and downshift
later.Fuel Economy Mode Switch
470 STARTING AND OPERATING

•The transmission will launch (from a stop) in second
gear.
• The torque converter clutch may engage at lower
engine speeds and remain on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
NOTE: ECO mode is only available in AUTO mode.
Active Noise Cancellation
Your vehicle is equipped with an Active Noise Cancella-
tion System, this system is designed to address the
change in exhaust noise whenever the vehicle is operat-
ing in Fuel Economy Mode (ECO) or 4 cylinder mode. This system relies on four microphones embedded in the
headliner to detect the exhaust drone and prompt an
onboard frequency generator to create counteracting
sound waves through the audio system’s speakers and
sub-woofer. This helps keep the vehicle quiet at highway
speeds.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
besides the gear selector bezel and in the Driver Infor-
mation Display (DID). To select a gear range, press the
lock button on the gear selector and move the lever
rearward or forward. To shift the transmission out of
PARK, the engine must be running and the brake pedal
must be pressed. You must also press the brake pedal to
shift from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). Select the DRIVE range for normal driving.5

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.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.
PARK (P)
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 shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
