Hold Mode Light
If your vehicle has this
feature, this light will come
on when the hold mode
is active.
If the HOLD mode light flashes, have your vehicle
checked. See “Hold Mode” under Automatic Transaxle
Operation on page 2-21 for additional information
on this feature.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The Check Engine light comes on
to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
Notice: If you keep driving your vehicle with
this light on, after awhile, your emission controls
may not work as well, your fuel economy may not be
as good, and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
Notice: Modifications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or replacement tires that do not match your
vehicle’s original tires can affect your vehicle’s
emission controls and may cause this light to
come on. Modifications to these systems could
lead to costly repairs not covered by your warranty.
This may also result in a failure to pass a required
Emission Inspection/Maintenance test.
