2007 CHRYSLER ASPEN check engine

on for 15 seconds as a bulb check. If the light does not
come on during starting, have the system checked by an
authorized dealer.
21. BRAKE System Warning Light
The red “BRAKE” warning light will come on when the
ignition key is first turned on, and stay on briefly as a
bulb check. If the bulb does not come on during starting,
have the bulb repaired promptly. If the light stays on, it
may be an indication that the parking brake has not been
released, or there is a low brake fluid level. If the light
remains on when the parking brake has been disengaged,
and the fluid level is at the full mark on the master
cylinder reservoir, it indicates a possible brake hydraulic
system malfunction or a problem with the Brake Booster.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
Booster the ABS pump will run when applying the brake.If the parking brake is applied, the light will flash when
the gear position is out of park for automatic transmis-
sions.
If brake failure is indicated, immediate repair is neces-
sary. Operating the vehicle in this condition is danger-
ous!
22. ESP/BAS Warning Lamp
The malfunction lamp for the ESP is combined
with BAS. The yellow “ESP/BAS Warning
Lamp” and the yellow “ESP/TCS Indicator
Light” in the instrument cluster both come on
when the ignition switch is turned to the “ON” position.
They should go out with the engine running. If the
“ESP/BAS Warning Lamp” comes on continuously with
the engine running, a malfunction has been detected in
either the ESP or the BAS system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles at speeds greater than 30 mph (48
km/h), see your authorized dealer as soon as possible.

NOTE:•TheESP/TCS Indicator Lightand theESP/
BAS Warning Lampcome on momentarily each time the
ignition switch is turned ON.•The ESP Control System
will make buzzing or clicking sounds when it is actively
operating.
23. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 10
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
194 INSTRUMENT PANEL AND CONTROLS

“P” Park
Supplements parking brake by locking the transmission.
Engine can be started in this range. Never use Park while
vehicle is in motion. Apply parking brake when leaving
vehicle in this range. Always apply parking brake first,
then place selector in Park position.
WARNING!
Your vehicle could move and injure you and others if
it is not completely in P (Park). Check by trying to
move the gearshift lever back and forth without first
pulling the lever toward you, after you have set it in
P (Park). Make sure it is in Park before leaving the
vehicle.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.

NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL” feature ON when driving in
hilly areas or shift the transmission to Drive position 2 on
more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t 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.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

Check the Battery Test Indicator (if equipped). If a light or
bright colored dot is visible in the indicator (if equipped),
DO NOT jump-start the battery.
If the indicator (if equipped) is dark or shows a green dot,
proceed as follows:
1. Wear eye protection and remove all metal jewelry such
as watch bands or bracelets which might make an
unintended electrical contact.
2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake, place
the automatic transmission in PARK and turn the ignition
OFF on both vehicles.
3. Turn OFF heater, radio and all unnecessary electrical
loads.4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine of the
vehicle with the discharged battery. Make sure you have
a good contact on the engine.

that the gas cap is properly tightened. Press the odometer
reset button to turn the message off. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system is determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine. If you crank or start the engine, you
will have to start this test over.

3. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
4. Approximately 15 seconds later, one of two things will
happen:
a. The MIL light will blink for approximately 5 sec-
onds and then remain on until the first engine crank or
the key is turned off. This means that your vehicle’s
OBD system isnot readyand you shouldnotproceed
to the I/M station.
b. The MIL light will remain fully illuminated until the
first engine crank or the key is turned off. This means
that your vehicle’s OBD system isreadyand you can
proceed to the I/M station.
If your OBD system isnot readyyou should see your
dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you mayneed to do nothing more than drive your vehicle as you
normally would in order for your OBD system to update.
A recheck with the above test routine may then indicate
that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
REPLACEMENT PARTS
Use of genuine Moparparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Moparparts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
