engine JEEP GRAND CHEROKEE 2013 WK2 / 4.G Owners Manual

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
•
Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations and
may cause the malfunction indicator light to turn on.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
•
When the fuel nozzle “clicks” or shuts off, the fuel tank is
full.
•Tighten the gas cap about one-quarter turn until you hear
one click. This is an indication that the cap is properly
tightened.
•If the gas cap is not tighten properly, the MIL will come
on. Be sure the gas cap is tightened every time the
vehicle is refueled.
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 down on the inboard edge of the left storage bin,
this will pop up the outboard edge.

552 STARTING AND OPERATING

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 manufacturers’ directions, it
provides 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.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine Model Frontal AreaMax. GTW (Gross
Trailer Wt.)Max. Trailer Tongue
Wt. (See Note)
3.6L 4x2 40 sq ft (3.72 sq m) 5,000 lbs (2 268 kg) 500 lbs (227 kg)
3.6L 4x4 40 sq ft (3.72 sq m) 5,000 lbs (2 268 kg) 500 lbs (227 kg)
5.7L 4x2 60 sq ft (5.57 sq m) 7,400 lbs (3 357 kg) 740 lbs (336 kg)
5.7L 4x4 60 sq ft (5.57 sq m) 7,200 lbs (3 266 kg) 720 lbs (327 kg)
Refer to local laws for maximum trailer towing speeds.
NOTE:The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to “Tire Safety
Information” in “Starting and Operating” for further
information. The addition of passengers and cargo may
require reducing trailer tongue load and Gross Trailer
Weight (GTW). Redistributing cargo (to the trailer) maybe necessary to avoid exceeding Rear Gross Axle Weight
Rating (GAWR) of 3,700 lbs (1 678 kg).
Trailer And Tongue Weight
Always load a trailer with 60% to 65% of the weight in the
front of the trailer. This places 10% to 15% of the GTW on the
tow hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to swayseverelyside
562 STARTING AND OPERATING

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.
•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:
•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.

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 an adaptive drive strategy
to avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, select
TOW/HAUL mode (if equipped), or a lower gear range
(using the Electronic Range Select [ERS] shift control).
NOTE:Using the TOW/HAUL mode (if equipped) or
selecting a lower gear range (using the ERS shift control)
while operating the vehicle under heavy loading condi-
tions, will improve performance and extend transmission
life by reducing excessive shifting and heat buildup. This
action will also provide better engine braking.If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the transmis-
sion fluid and filter(s) as specified for “police, taxi, fleet,
or frequent trailer towing.” Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
NOTE:Check the transmission fluid level before towing
(5.7L engine).
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.5

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.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
shouldnotbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
