ECU JEEP PATRIOT 2017 1.G Service Manual

Trailer And Tongue Weight
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
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 consid-
ered as part of the total load on your vehicle. Refer to the
“Tire And Loading Information” placard for the maximum
combined weight of occupants and cargo for your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended:
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 that it will not shift during travel. When traile-
ring 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

DRIVING TIPS
On-Road Driving Tips
Utility vehicles have higher ground clearance and a nar-
rower track to make them capable of performing in a wide
variety of off-road applications. Specific design character-
istics give them a higher center of gravity than conven-
tional passenger cars.
An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as
conventional passenger cars any more than low-slung
sports cars are designed to perform satisfactorily in off-
road conditions. Avoid sharp turns or abrupt maneuvers.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or vehicle
rollover.
Off-Road Driving Tips
You will encounter many types of terrain driving off-road.
You should be familiar with the terrain and area before
proceeding. There are many types of surface conditions:
hard packed dirt, gravel, rocks, grass, sand, mud, snow
and ice. Every surface has a different effect on your
vehicle’s steering, handling and traction. Controlling yourvehicle is one of the keys to successful off-road driving, so
always keep a firm grip on the steering wheel and maintain
a good driving posture. Avoid sudden accelerations, turns
or braking. In most cases there are no road signs, posted
speed limits or signal lights. Therefore you will need to use
your own good judgment on what is safe and what is not.
When on a trail, you should always be looking ahead for
surface obstacles and changes in terrain. The key is to plan
your future driving route while remembering what you are
currently driving over.
CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.

WARNING!(Continued)
•If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely
stowed, spares must be stowed with the valve stem
facing the ground.
NOTE: Refer to “Tires — General Information” in “Servic-
ing And Maintenance” for further information about the
spare tire, it’s use, and operation. 1. Remove the scissors jack and lug wrench from the spare
wheel as an assembly. Turn the jack screw to the left to
loosen the lug wrench and remove the wrench from the
jack assembly.
NOTE: The jack handle attaches to the side of the jack with
two attachment points. When the jack is partially ex-
panded, the tension between the two attachment points
holds the jack handle in place.
2. Loosen, but do not remove, the wheel nuts by turning them to the left one turn while the wheel is still on the
ground.
Jack Warning Label
Removing Jack Handle From Jack
252 IN CASE OF EMERGENCY

Do not raise the vehicle until you are sure the jack is
securely engaged.
3. Turn the jack screw to the left until the jack can be placedunder the jacking location. Once the jack is positioned,
turn the jack screw to the right until the jack head is
properly engaged with the lift area closest to the wheel
to be changed.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
4. Using the swivel wrench raise the vehicle by turning the jack screw to the right. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
5. Remove the wheel nuts and pull the wheel and wheel covers, where applicable, off the hub. Install the spare
wheel and wheel nuts with the cone shaped end of the
nuts toward the wheel. Lightly tighten the nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
Rear Jacking Location
254 IN CASE OF EMERGENCY

WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp edges.
CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.NOTE:
The wheel cover is held on the wheel by the wheel
nuts. When reinstalling the original wheel, properly align
the wheel cover to the valve stem, place the wheel cover
onto the wheel, then install the wheel nuts.
6. Lower the vehicle by turning the jack screw to the left.
7. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until each
nut has been tightened twice. Refer to “Torque Specifi-
cations” in “Technical Specifications” for the correct lug
nut torque. If you doubt that you have tightened the
nuts correctly, have them checked with a torque wrench
by your authorized dealer or service station.
8. Remove the wheel blocks and lower the jack until it is free. Release the parking brake. Reassemble the lug
wrench to the jack assembly and stow it in the spare tire
area. Secure the assembly using the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

SERVICING AND MAINTENANCE 289

Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
(Continued)
WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
CAUTION!
Use of improper brake fluids will affect overall clutch
system performance. Improper brake fluids may dam-
age the clutch system resulting in loss of clutch func-
tion and the ability to shift the transmission.
