2015 JEEP GRAND CHEROKEE engine

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
•A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use the fuel
filler door emergency release.
1. Open the liftgate.
2. Push the inboard edge of the left storage bin to the
center, this will pop up the outboard edge.
3. Grab popped up outboard edge with other hand to
disengage snaps.
4. Remove the storage bin.
5. Pull the release cable to open the fuel door, push the
release cable back to the home position to re-seat the
fuel door latch to the closed position.

Trailer Sway Control
The trailer sway control can be a mechanical telescoping
link that can be installed between the hitch receiver and
the trailer tongue that typically provides adjustable fric-
tion associated with the telescoping motion to dampen
any unwanted trailer swaying motions while traveling.
If equipped, the electronic Trailer Sway Control (TSC)
recognizes a swaying trailer and automatically applies
individual wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the vehicle. These kinds
of hitches are the most popular on the market today and
they are commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age through spring (load) bars. They are typically used
for heavier loads to distribute trailer tongue weight to the
tow vehicle’s front axle and the trailer axle(s). When used
in accordance with the manufacturer’s directions, it pro-
vides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.

Refer to local laws for maximum trailer towing speeds.
546 STARTING AND OPERATING

Consider the following items when computing the
weight on the rear axle of the vehicle:
•The tongue weight of the trailer
•The weight of any other type of cargo or equipment
put in or on your vehicle
•The weight of the driver and all passengers
NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to “Tire Safety Information/Tire and Loading In-
formation Placard” in “Starting and Operating” for fur-
ther information.
Towing Requirements
To promote proper break-in of your new vehicle drive-
train components, the following guidelines are recom-
mended.
CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.

STARTING AND OPERATING 549

CAUTION!(Continued)
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
Perform the maintenance listed in the “Maintenance
Schedule.” Refer to “Maintenance Schedule” for the
proper maintenance intervals. When towing a trailer,
never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
(Continued)
WARNING!(Continued)
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
Paddle Shift switches to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.

554 STARTING AND OPERATING

Paddle Shift Mode
•When using the Paddle Shift switches, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
•To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
•Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

STARTING AND OPERATING 555

NOTE:
•When recreationally towing your vehicle, always fol-
low applicable state and provincial laws. Contact state
and provincial Highway Safety offices for additional
details.
•Vehicles equipped with Quadra-Lift™ must be placed
in Transport Mode before tying them down (from the
body) on a trailer or flatbed truck. Refer to “Quadra-
Lift™ – If Equipped” in “Starting and Operating” for
more information. If the vehicle cannot be placed in
Transport mode (for example, engine will not run),
tie-downs must be fastened to the axles (not to the
body). Failure to follow these instructions may cause
fault codes to be set and/or cause loss of proper
tie-down tension.
Recreational Towing – Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLY if the rear wheels are OFF the ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Shift the transmission
into PARK.
4. Turn the ignition switch to the OFF position.
5. Properly secure the rear wheels to the dolly, following
the dolly manufacturer ’s instructions.
