Safety belt
Momentarily illuminates
when the ignition is
turned to the ON
position to remind you
to fasten your safety belts. For more information,
refer to theSeating and safety restraintschapter.
Door ajar
Illuminates when the
ignition is in the ON or
START position and
any door is open.
Service engine soon
Your vehicle is
equipped with a
computer that monitors
the engine's emission
control system. This
system is commonly known as the On Board
Diagnostics System (OBD II). The OBD II system
protects the environment by ensuring that your
vehicle continues to meet government emission
standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
TheService Engine Soonindicator light illuminates
when the ignition is first turned to the ON position
to check the bulb. If it comes on after the engine is
started, one of the engine's emission control systems
may be malfunctioning. The light may illuminate
without a driveability concern being noted. The
vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon
light illuminates
Light turns on solid:
This means that the OBD II system has detected a
malfunction.

BRAKES
Your service brakes are self-adjusting. Refer to the
scheduled maintenance guide for scheduled
maintenance.
Occasional brake noise is normal and often does not
indicate a performance concern with the vehicle's
brake system. In normal operation, automotive brake
systems may emit occasional or intermittent squeal
or groan noises when the brakes are applied. Such
noises are usually heard during the first few brake
applications in the morning; however, they may be
heard at any time while braking and can be
aggravated by environmental conditions such as
cold, heat, moisture, road dust, salt or mud. If a
ªmetal-to-metalº, ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking,
the brake linings may be worn-out and should be
inspected by a qualified service technician.
Anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be observed
during ABS braking events. Pedal pulsation coupled
with noise while braking under panic conditions or
on loose gravel, bumps, wet or snowy roads is
normal and indicates proper functioning of the
vehicle's anti-lock brake system. The ABS performs a
self-check at 17 km/h (10 mph) after you start the
engine and begin to drive away. A brief mechanical
noise may be heard during this test. This is normal.
If a malfunction is found, the ABS warning light will
come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the
vehicle should be inspected by a qualified service
technician.

operated in the top cruise gear and with steady
pressure on the gas pedal.
²Close windows for high speed driving.
Maintenance and care
174

Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine compartment
and exhaust system, which can start a fire.
Illumination of the charging system warning light,
ªService Engine Soonº light or the temperature
warning light, fluid leaks, strange odors, smoke or
loss of oil pressure, could indicate that the emission
control system is not working properly.
Exhaust leaks may result in entry of harmful
and potentially lethal fumes into the
passenger compartment.
Do not make any unauthorized changes to your
vehicle or engine. By law, vehicle owners and anyone
who manufactures, repairs, services, sells, leases,
trades vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an emission
control device or prevent it from working.
Information about your vehicle's emission system is
on the Vehicle Emission Control Information Decal
located on or near the engine. This decal identifies
engine displacement and gives some tune up
specifications.
Please consult your ªWarranty Guideº for complete
emission warranty information.
Readiness for Inspection/Maintenance (I/M)
testing
In some localities, it may be a legal requirement to
pass an I/M test of the on-board diagnostics system.
If your ªCheck Engine/Service Engine Soonº light is
on, refer to the description in theWarning Lights
and Chimessection of theInstrumentation
chapter. Your vehicle may not pass the I/M test with
