ignition JEEP COMPASS 2007 1.G Repair Manual

If Engine Fails to Start
If the engine fails to start after you have followed the
“NORMAL STARTING” procedure, it may be flooded.
Push the accelerator pedal all the way to the floor and
hold it there. Crank the engine for no more than 15
seconds. This should clear any excess fuel in case the
engine is flooded. Leave the ignition key in the ON
position, release the accelerator pedal and repeat the
“NORMAL STARTING” procedure.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
After Starting
The idle speed will automatically decrease as the engine
warms up.
234 STARTING AND OPERATING

WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON or ACC positions. Always depress the
brake pedal first,before moving the gear selector out of
PARK.NOTE:If a malfunction occurs, the transaxle will not
shift out of park. Battery power is required to release the
brake/transmission interlock system. There is a remov-
able plug in the right side of the shifter housing that
allows you to insert your finger to override the system.
The key must be in the ignition and in the on position to
use the override lever. If this occurs obtain service as
soon as possible.
Automatic Transaxle Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ACC or ON positions, and
the brake pedal is depressed.
NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
236 STARTING AND OPERATING

Gear Ranges For Continuously Variable
Automatic Transaxle (CVT)
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
“P” Park
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never use P
(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 selector
in P (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 P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
shift lever is locked in the P (Park) position, securing
the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
STARTING AND OPERATING 237

The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
•When shifting into P (Park), firmly move the lever all
the way forward until it stops.
•Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
•You must depress the brake pedal to move the shift
lever out of the P (Park) position.
CAUTION!
Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK to ON so the
steering wheel and shift lever are released. Other-
wise, damage to the steering column or shifter could
result. You must also depress the brake pedal.
“R” Reverse
Shift into this range only after the vehicle has come to a
complete stop.
“N” Neutral
Engine may be started in this range.
“D”
This should be used for most driving and provides the
best ratio for optimum driveability, fuel economy, and
performance.
“L” Low
This range should be used for maximum engine braking
when descending steep grades. In this range, the trans-
axle will ratio up only to prevent transaxle damage or
engine over speed while ratioing down will occur as
early as possible
238 STARTING AND OPERATING

Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose
traction surfaces, activate the 4WD Lock switch by pull-
ing up once and releasing. This locks the center coupling
allowing more torque to be sent to the rear wheels. The
amber4WDlight will come on in the cluster. This can be
done on the fly, at any vehicle speed. To deactivate,
simply pull on the switch one more time. The cluster light
will then go out.
NOTE:Refer to ”ESP (Electronic Stability Program) in
the “Electronic Brake Control System” section of this
manual for additional information.PARKING BRAKE
When the parking brake is applied with the
ignition on, the Brake Light in the instrument
cluster will come on.
NOTE:This light only shows that the parking brake is
on. It does not show the degree of brake application.
If the parking brake is applied while the vehicle is
moving, a chime will sound to alert the driver. The chime
will sound up to 10 times or until the vehicle has
returned to a stop.
Before leaving the vehicle, make sure that the parking
brake is set. To set the parking brake, pull up firmly on
the lever. Also place the gear selector in the Park position
(automatic transaxle) or Reverse (manual transaxle). To
release the parking brake, apply the brake pedal, pull up
244 STARTING AND OPERATING

WARNING!
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector.
Don’t leave the keys in the ignition. A child could
operate power windows, other controls, or move
the vehicle.
•Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and an accident.
BRAKE SYSTEM
Your vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications
with the engine off), the brakes will still function. How-
ever, the effort required to brake the vehicle will be much
greater than that required with the power system oper-
ating.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
246 STARTING AND OPERATING

WARNING!
•Anti-lock system (ABS) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase braking or steering efficiency be-
yond that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
The ABS light monitors the Anti-Lock Brake
System. The light will come on when the
ignition switch is turned to the ON position
and may stay on for as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
248 STARTING AND OPERATING

•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. The audible chime will sound once
every ignition cycle for each condition that it detects. In
addition, the Electronic Vehicle Information Center
(EVIC) will display a graphic of the pressure value(s)
with the low tire(s) flashing.NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.
NOTE:A low spare tire will not cause the Tire Pressure
Monitoring Telltale Lamp to illuminate or the chime to
sound.
Low Tire Pressure Display
STARTING AND OPERATING 271

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and theCHECK TPM SYS-
TEMtext message will no longer display.
NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.
NOTE:If your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the compact spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Lamp” to be ON, a
chime to sound, and the Electronic Vehicle Information
Center (EVIC) will still show the low tire pressure value
flashing on the graphic display. However, driving the
vehicle for up to 10 minutes above 15 mph (25 km/h) willdisplay a “CHECK TPM SYSTEM” text message on the
EVIC. This text message will then be followed by a
graphic, with “- -“ in place of the flashing low pressure
value. For every subsequent key cycle, the “Tire Pressure
Monitoring Lamp” will be ON, a chime will sound, a
“CHECK TPM SYSTEM” text message will be display in
the EVIC, and the graphic display will have “- -“ in place
of the pressure value of the spare tire location. Once the
original road tire has been properly repaired, and put
back onto the vehicle in place of the compact spare tire.
The TPMS will update the graphic display on the EVIC
with a new tire pressure value instead of “- -“, and the
“Tire Pressure Monitoring Lamp” will be OFF as long as
none of the road tire(s) are below the low pressure
warning threshold. The vehicle may need to be driven for
up to 10 minutes above 15 mph (25 km/h) to receive this
information.

•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
