ECU JEEP PATRIOT 2013 1.G Service Manual

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 two-wheel drive vehicles any more than
low-slung sports cars are designed to perform satisfacto-
rily in off-road conditions. If at all possible, 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. Control-
ling your vehicle 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 suddenaccelerations, 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
combustible 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.
330 STARTING AND OPERATING

The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier suspension compo-
nents do not necessarily increase the vehicle’s GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight. Store heavier items down low and be sure you
distribute their weight as evenly as possible. Stow all
loose items securely before driving. Improper weight
distribution can have an adverse effect on the way your
vehicle steers and handles, and the way the brakes
operate.
CAUTION!
Do not load your vehicle any heavier than the
GVWR. If you do, parts on your vehicle can break, or
it can change the way your vehicle handles. This
could cause you to lose control. Also, overloading can
shorten the life of your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
398 STARTING AND OPERATING

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 frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and allow
enough slack for turning corners.
(Continued)
WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. Always block or chockthe
trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.

Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
• Never start or run the engine with the vehicle on a
jack.
(Continued)
WARNING! (Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• 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 out.
418 WHAT TO DO IN EMERGENCIES

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
placed under 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.

422 WHAT TO DO IN EMERGENCIES

WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp
edges.
NOTE: The wheel cover is held on the wheel by the
wheel nuts. When reinstalling the original wheel, prop-
erly 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 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. The correct wheel nut torque is
100 ft lbs (135 N·m). 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 ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
9. Place the deflated (flat) tire in the cargo area, have the
tire repaired or replaced as soon as possible.
424 WHAT TO DO IN EMERGENCIES

All Transmissions
If you must use the accessories (wipers, defroster, etc.)
while being towed, the key must be in the ON/RUN
position, not the ACC position. Make certain the trans-
mission remains in NEUTRAL.
If the battery is discharged, see “Shift Lever Override” in
“What To Do In Emergencies” for instructions on shifting
the automatic transmission out of PARK for towing.
CAUTION!
DO NOT use sling-type equipment when towing.
When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
436 WHAT TO DO IN EMERGENCIES

MAINTAINING YOUR VEHICLE 451

WARNING!(Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder 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 pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
• 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.
WARNING! (Continued)
•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.
Automatic Transmission – If Equipped
Selection Of Lubricant (CVT)
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s recommended transmission
