REDUCED ENGINE POWER: You will hear chimes
continuously when this message is displayed. To
acknowledge that you have read the message and to
remove it from the display, press RESET. The message
will reappear every 15 seconds until this condition
changes.
If the Driver Information Center (DIC) displays the
REDUCED ENGINE POWER message and the CHECK
ENGINE light comes on, a noticeable reduction in the
vehicle's performance may occur. If the REDUCED
ENGINE POWER message is displayed but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time
the vehicle is driven.
The vehicle may be driven at a reduced speed while
the REDUCED ENGINE POWER message is displayed,
but acceleration and speed may be reduced. Anytime
the CHECK ENGINE light stays on, the vehicle
should be taken to an authorized dealer as soon as
possible for diagnosis and repair.
Also, refer to Malfunction Indicator Lamp on page 3-41.
If the REDUCED ENGINE POWER message is
displayed in combination with the COOLANT OVER
TEMP message, see Engine Overheating on page 5-26.

REDUCE ENGINE RPM: You will hear four chimes
when this message is displayed. To acknowledge the
warning, press the RESET button. After you press the
RESET button, a message will be displayed and you will
hear a chime every minute until this condition changes.
If you do not press RESET, the message will remain on
the digital display until the condition changes.
If the engine oil temperature exceeds 320°F (160°C),
this message is displayed. You should check the engine
coolant temperature and engine oil level. If your engine is
too hot, see Engine Overheating on page 5-26. Your
vehicle may need service, so see your dealer. You can
monitor the oil temperature with the GAGES button on
the DIC.
SERVICE ABS (Anti-Lock Brake System): If the
SERVICE ABS message is displayed when you
are driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the message stays on, or comes back
on again while you are driving, your vehicle is in need
of service. If the regular brake system warning light
is not on, you still have brakes, but do not have anti-lock
brakes. If the regular brake system light is also on,
you do not have anti-lock brakes and there is a problem
with your brakes. See Brake System Warning Light
on page 3-38.
