Note: Some warning indicators appear in
the information display and operate the
same as a warning lamp but do not
illuminate when you start your vehicle.

power park parking brake option: If the park
brake warning lamp begins to blink after

setting the parking brake, this may indicate
a failure in the parking brake system. Seek

immediately. Driving extended distances
with the parking brake engaged can cause
brake failure and the risk of personal injury.

Power/Electronic Throttle Control

(If Equipped)

powertrain fault. Contact an
authorized dealer as soon as

possible.

Service Engine Soon

If it illuminates when the engine
is running this indicates a

converter or other vehicle components.
Drive in a moderate fashion (avoid heavy
acceleration and deceleration) and have
your vehicle immediately serviced.

It illuminates when you switch the ignition
on prior to engine start to check the bulb
and to indicate whether your vehicle is
ready for Inspection and Maintenance
(I/M) testing.

Normally, it illuminates until the engine is
cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.

See Catalytic Converter (page 103).

filter/water separator has a
significant quantity of water in

it.

If the light illuminates when the engine is
