warning light JEEP COMPASS 2018 Owner handbook (in English)

The dual brake system provides a reserve brak-
ing capacity in the event of a failure to a portion
of the hydraulic system. A leak in either half of
the dual brake system is indicated by the Brake
Warning Light, which will turn on when the
brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
four seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.

— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engineand automatic transmission control systems.
The light will illuminate when the ignition is
in the ON/RUN position before engine start.
If the bulb does not come on when turning
the ignition switch from OFF to ON/RUN,
have the condition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
WARNING!
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle 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.

SERV4WD— Service 4WD Warning Light — If
Equipped
If the light stays on or comes on during
driving, it means that the 4WD system is not
functioning properly and that service is re-
quired. We recommend you drive to the near-
est service center and have the vehicle ser-
viced immediately.
— Service Stop/Start System Warning
Light — If Equipped
This telltale will turn on to indicate the Stop/
Start system is not functioning properly and
service is required. Contact your authorized
dealer for service.
— Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel con-
sumption may not be guaranteed.Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in
sequence.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp
braking and steering. If a tire puncture
occurs, repair immediately using the dedi-
cated tire repair kit and contact your au-
thorized dealer as soon as possible.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
67

flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
CAUTION!
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to your authorized dealer to have your
sensor function checked.

EMISSIONS INSPECTION
AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal require-
ment to pass an inspection of your vehicle's
emissions control system. Failure to pass
could prevent vehicle registration.
Normally, the OBD II system will be
ready. The OBD II system maynot
be ready if your vehicle was re-
cently serviced, recently had a
dead battery or a battery replacement. If the
OBD II system should be determined not
ready for the I/M test, your vehicle may fail
the test.
Your vehicle has a simple ignition actuated
test, which you can use prior to going to the
test station. To check if your vehicle's OBD II
system is ready, you must do the following:
1. Cycle the ignition switch to the ON posi-
tion, but do not crank or start the engine.NOTE:
If you crank or start the engine, you will
have to start this test over.
2. As soon as you cycle the ignition switch to
the ON position, you will see the “Mal-
function Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of
two things will happen:
• The MIL will flash for about ten seconds
and then return to being fully illuminated
until you turn OFF the ignition or start the
engine. This means that your vehicle's OBD
II system isnot readyand you shouldnot
proceed to the I/M station.
• The MIL will not flash at all and will remain
fully illuminated until you place the igni-
tion in the off position or start the engine.
This means that your vehicle's OBD II sys-
tem isreadyand you can proceed to the I/M
station.
