ECU JEEP COMPASS 2010 1.G Owner's Guide

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, and then place the
shift lever in the PARK position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into PARK, remove the key from the
ignition, and apply the parking brake. Once the key
is removed from the ignition, the shift lever is locked
in the PARK position, securing the vehicle against
unwanted movement. Furthermore, you should never
leave unattended children inside a vehicle.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, firmly move the shift lever
all the way forward until it stops.
284 STARTING AND OPERATING

Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.
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.

STARTING AND OPERATING 343

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 further
information. When towing a trailer, never exceed the
GAWR, or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident.
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 an accident.
•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, transaxle, 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)

STARTING AND OPERATING 349

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.
•Turn on the Hazard Warning flasher.
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. 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 LabelJacking Locations

WHAT TO DO IN EMERGENCIES 363

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in Step 3.
3. There are two front jacking locations and two rear
jacking locations on each side of the body. The front
locations are outlined by two triangular cutouts, the rear
ones by two rectangular cutouts. For vehicles equipped
with plastic trim, the plastic has been cut away to expose
the jacking locations in the body.
Do not raise the vehicle until you are sure the jack is
securely engaged.
4. 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.
5. 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.
6. 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. To avoid
the risk of forcing the vehicle off the jack, do not tighten
the nuts fully until the vehicle has been lowered.
364 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.
7. Lower the vehicle by turning the jack screw to the left.
8. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts 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. 9. Remove the wheel blocks and lower the jack until it is
free. 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.
10. Place the deflated (flat) tire in the cargo area, have the
tire repaired or replaced as soon as possible.
WARNING!
A loose tire thrown forward in a collision or hard stop
could injure the occupants in the vehicle. Have the
deflated (flat) tire repaired or replaced immediately.

WHAT TO DO IN EMERGENCIES 365

CAUTION!
DO NOT flat tow any vehicle equipped with an
automatic transmission. Damage to the drivetrain
will result.
Manual Transaxle
•
Front Wheel Drive (FWD) or All Wheel Drive (AWD)
vehicles can be flat towed (all four wheels on the
ground) with the transmission in NEUTRAL.
•FWD vehicles can be towed with the front wheels
elevated.
•FWD or AWD vehicles can be towed on a flatbed truck
(all wheels off the ground).
All Transaxles
If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACC position. Make certain the trans-
mission remains in NEUTRAL.
CAUTION!
•If the vehicle being towed requires steering, the
ignition switch must be in the ACC position, not
in the LOCK position.
•Do not attempt to use sling-type equipment when
towing. When securing the vehicle to a flatbed
truck, do not attach to front or rear suspension
components. Damage to your vehicle may result
from improper towing.
372 WHAT TO DO IN EMERGENCIES

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 prolonged braking, resulting in sudden brake
failure. This could result in a accident.
•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.(Continued)
WARNING! (Continued)
•Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in an accident.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake fluids
may damage the clutch system resulting in loss of
clutch function and the ability to shift the transaxle.
Automatic Transaxle (CVT) – If Equipped
Selection Of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only the manufacturer’s recommended transmission
