The vehicle may be driven with the engine air filter warning light
illuminated/or when the underhood air filter restriction gauge has moved
to the CHANGE FILTER mark for up to 400 km (250 miles) without
damaging the engine or related components. However, the air filter
element must be replaced at the earliest opportunity. Refer toAir filter
restriction gauge (if equipped)in this section of the supplement for
more information.
Transmission Tow/Haul Feature
(if equipped):Illuminates when
the Tow/Haul feature has been
selected. Refer to theDriving
chapter for transmission function and operation. If the light flashes
steadily or does not illuminate, have the transmission serviced soon, or
damage may occur.
Air filter restriction gauge (if equipped)
The restriction gauge, located on
the upper housing of the air cleaner
assembly, monitors the condition of
the air filter element in two ways:
•First, the colored indictor inside
the gauge highlights the
percentage that the air filter
element is clogged with dust or
contaminants. Refer to
Maintenance and Specifications
section of this supplement.
•Second, the gauge contains an
electrical switch which illuminates
a warning light on the instrument
cluster when the air filter element
is 100% clogged. Refer to the
Engine air filterwarning light in
this section of the supplement.
Check the air filter restriction gauge
whenever the hood is raised to
perform general engine maintenance at least every 7,500 miles (12,000
km). If the vehicle is operated in extremely dusty conditions, check the
gauge at least every 500 miles (800 km), or two weeks, whichever comes
first.
