may appear in the HUD:
CRUISE SPEED LIMITED:This message indicates that
the vehicle speed has been reduced below the set
speed due to ACC limitations. The set speed is too high
and ACC cannot detect other vehicles at far enough
distances for the system to operate properly.
TIGHT CURVE:This message indicates that ACC
has reduced the vehicle speed due to a tight curve in
the road. Once the road straightens, ACC will return to
the selected set speed or follow distance setting.
See “Adaptive Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 3-7for more
information.
You may also see an ACC active symbol, alert symbol

Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air, including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced early.
The lter should be replaced as part of the routine
scheduled maintenance. SeeScheduled Maintenance
on page 7-4for more information.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
The passenger compartment air lter and access
panel are located on the passenger side of the
engine compartment near the battery. SeeEngine
Compartment Overview on page 6-12for more
information on location.
2. Pull the old lter out of the housing.
3. Insert the new lter into the housing.
4. Reinstall the air lter access panel.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to the warning lights and gages could prevent injury.
Warning lights come on when there may be or is
a problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
3-41

Charging System Light
This light comes on briey
when the ignition key is
turned to START, but
the engine is not running,
as a check to show it
is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-60for more
information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of the
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when the vehicle is at 10 volts or below. Have it checked
right away. Driving with the voltmeter reading at
10 volts or below could drain the battery and disable
the vehicle.
