2017 JEEP GRAND CHEROKEE ECO mode

Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving,
have the system inspected at an authorized dealer as
soon as possible. This light will illuminate with a single
chime when a fault with the Air Bag Warning Light has
been detected, it will stay on until the fault is cleared. If
the light comes on intermittently or remains on while
driving, have an authorized dealer service the vehicle
immediately. Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost mode and place the
blower control on high speed. You should be able to feel the
air directed against the windshield. See your authorized
dealer for service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only use
a floor mat that does not interfere with the operation of the
accelerator, brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat fasteners so it cannot
slip out of position and interfere with the accelerator, brake
or clutch pedals or impair safe operation of your vehicle in
other ways.

cluster display. Refer to “Instrument Cluster Display“ in
“Getting to Know Your Instrument Panel” for further
information.
If the “SERVICE STOP/START SYSTEM” message appears
in the instrument cluster display, have the system checked
by your authorized dealer.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord. The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is located:
•
3.6L Engine — Coiled and strapped to the engine oil
dipstick tube.
• 5.7L Engine — Bundled and fastened to the injector
harness.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS — 3.6L &
5.7L ENGINES
For vehicles equipped with the 3.6L or 5.7L use the
following engine break-in recommendations:A long
break-in period is not required for the drivetrain (engine,
transmission, clutch, and rear axle) in your new vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
270 STARTING AND OPERATING

WARNING!(Continued)
touch the parking brake, brake pedal or the trans-
mission gear selector.
• 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 following
precautions are not observed:
• Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• 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.
Ignition Park Interlock
This vehicle is equipped with a Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. 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 is in the
OFF mode.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission 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 vehicle’s
overall fuel economy during normal driving conditions.
Push the “ECO” switch in the center stack of the instru-
ment panel to activate or disable ECO mode. An amber
274 STARTING AND OPERATING

light on the switch indicates when ECO mode is disabled
(for regular models) or a blue light when enabled (for SRT
models).
When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
• The overall driving performance will be more conserva-
tive. •
Vehicles with Quadra-Lift air suspension will operate in
Aero mode over a broader speed range. Refer to the
section on Quadra-Lift for further information.
• In SRT models, the transmission will launch (from a
stop) in second gear, and the torque converter clutch
may engage at lower engine speeds and remain on
longer.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation — Summit And SRT
Models Only
Your vehicle is equipped with an Active Noise Cancellation
System. This system uses four microphones embedded in
the headliner to detect undesirable exhaust noise, which
sometimes occurs when operating in ECO mode. An
onboard frequency generator creates counteracting sound
waves through the audio system to help keep the vehicle
quiet.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To
