ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and automatic trans-
mission control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light” (MIL). It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
(Continued)
CAUTION! (Continued)
•If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of

WARNING!(Continued)
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Privacy Practices — If
Equipped With Uconnect 8.4 Radio” and “Uconnect Cy-
berSecurity” in “All About Uconnect Access” in your
Owner ’s Manual Radio Supplement and “Cybersecurity”
in “Understanding Your Instrument Panel”.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the instrument
cluster. If this occurs, tighten the fuel filler cap properly
and press the Trip Odometer button to turn off the mes-
sage. If the problem continues, the message will appear the
next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
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 that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, or 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 follow-
ing:
1. Cycle the ignition to the ON mode, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.

WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. 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 would not have your full braking
capacity in an emergency.
Master Cylinder — Brake Fluid Level Check
Check the fluid level in the master cylinder immediately if
the brake system warning light indicates system failure.
Check the fluid level in the master cylinder when perform-
ing underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the “MAX” mark
on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the requirements
described on the brake fluid reservoir. With disc brakes,fluid level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids, Lubricants, And Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der 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
