2016 JEEP GRAND CHEROKEE fuel

•ECO MODE — This mode modifies the vehicle’s
engine and transmission settings to provide improved
fuel economy at a trade-off with acceleration perfor-
mance. Increased engine exhaust noise and/or vibra-
tion may be noticed while Eco is active, this is normal
and will not damage the vehicle.
NOTE: Changing the Drive Mode will deactivate Eco.
Launch Control — If Equipped
This vehicle is equipped with a Launch Control system
that is designed to allow the driver to achieve maximum
vehicle acceleration in a straight line. Launch Control is a
form of traction control that manages tire slip while
launching the vehicle. This feature is intended for use
during race events on a closed course where consistent
quarter mile and zero to sixty times are desired. The
system is not intended to compensate for lack of driver
experience or familiarity with the race track. Use of this feature in low traction (cold, wet, gravel, etc.) conditions
may results in excess wheel slip outside this systems
control resulting in an aborted launch.
Preconditions:
•
Launch Control should not be used on public roads.
Always check track conditions and the surrounding
area.
• Launch Control is not available within the first 500
miles (805 km) of engine break-in.
• Launch Control should only be used when the engine
and transmission are at operating temperature.
• Launch Control is intended to be used on dry, paved
road surfaces only.

Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to ”Customer Pro-
grammable Features” within “Uconnect Settings” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEER-
ING” or the “POWER STEERING ASSIST OFF
– SERVICE SYSTEM” message is displayed
within the Driver Information Display (DID), this indi-
cates the vehicle needs to be taken to the dealer for service. Refer to “Driver Information Display (DID)” in
“Understanding Your Instrument Panel” for further in-
formation.
NOTE:
•
Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
FUEL SAVER TECHNOLOGY — IF EQUIPPED
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.

WARNING!(Continued)
•Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the
right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnor-
mal wear patterns and reduced tread life, resulting in the
need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side
door.
534 STARTING AND OPERATING

•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:
It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.

FUEL REQUIREMENTS
6.4L Engine
This engine is designed to meet all
emission regulations, provide optimal
fuel economy and performance when
using high-quality unleaded “Pre-
mium” gasoline having a posted oc-
tane number of 91 as specified by the
(R+M)/2 method. The use of 91 or
higher octane “Premium” gasoline is required for in this
engine.
While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine
is not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with a lower than recommended octane number can cause engine failure and may void or
not be covered by the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consid-
ering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.

STARTING AND OPERATING 555

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 15% ethanol (E-15). Use of
these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the “Malfunction Indicator Light” to
illuminate. Please observe pump labels as they
should clearly communicate if a fuel contains greater
than 15% ethanol (E-15).
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited
Warranty.
Modifications that allow the engine to run on com-
pressed natural gas (CNG) or liquid propane (LP) may
result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufacturer
and many void or not be covered under the New Vehicle
Limited Warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 15% ethanol (E-15). Gasoline with
higher ethanol content may void the New Vehicle Lim-
ited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
556 STARTING AND OPERATING

•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump, therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines
that have these additives will help improve fuel
economy, reduce emissions, and maintain vehicle perfor-
mance.
Designated TOP TIER Detergent Gaso-
line contains a higher level of deter-
gents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of Top Tier
Detergent gasoline is recommended.

Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum
and varnish removal may contain active solvents or
similar ingredients. These can harm fuel system gasket
and diaphragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine per-
formance and damage the emissions control
system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
(Continued)
CAUTION! (Continued)
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
• The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
