Engine Power Messages

ENGINE POWER IS REDUCED
This message displays and a
chime sounds when the cooling
system temperature gets too hot
and the engine further enters the
engine coolant protection mode.
See Engine Overheating on
page 10 22 for further information.
This message also displays when
the vehicle's engine power is
reduced. Reduced engine power
can affect the vehicle's ability to
accelerate. If this message is on,
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 this
message is on, but acceleration and
speed may be reduced. Anytime
this message stays on, the vehicle
should be taken to your dealer for
service as soon as possible.

Fuel System Messages

FUEL LEVEL LOW
This message displays and a chime
sounds if the fuel level is low. Refuel
as soon as possible. See Fuel
Gauge on page 5 15 and Fuel on
page 9 73 for more information.
TIGHTEN GAS CAP
This message may display along
with the check engine light on the
instrument panel cluster if the
vehicle's fuel cap is not tightened
properly. See Malfunction Indicator
Lamp on page 5 22. Reinstall the
fuel cap fully. See Filling the Tank
on page 9 77. The diagnostic
system can determine if the fuel
cap has been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into the
atmosphere. A few driving trips with
the cap properly installed should
turn this light and message off.
