Passenger Compartment Air Filter
The passenger compartment air lter helps remove dust
and pollen from the air entering the vehicle. Like the
vehicle’s engine air cleaner/lter, it needs to be changed
periodically. For how often to change the passenger
compartment air lter, seeScheduled Maintenance on
page 6-4.
The passenger compartment air lter is located
underneath the hood below the windshield wiper arm
on the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location.Use the procedure listed below to replace the passenger
compartment air lter:
1. Open the hood to access the engine compartment.
SeeHood Release on page 5-11for more
information. Locate the passenger compartment air
lter access panel door.
2. Push the two tabs on the access panel door
towards the windshield.

3. While pressing forward, lift the access panel out
of the clipped position and pull towards the front
of the vehicle. This releases the clips and allows
the panel door to be removed.
4. Remove the old lter and insert a new one.
Make sure the arrow on the lter is pointing toward
the passenger compartment.
SeeMaintenance Replacement Parts on page 6-15
for the correct part number for the lter.
5. Reverse Steps 1 through 3 to reinstall the cover.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.

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). See
“SPEEDOMETER” underDIC Operation and Displays
on page 3-46for more information.
The odometer mileage can be checked without the
vehicle running. Your vehicle’s odometer works together
with the driver information center. You can set a
Trip A and a Trip B odometer. See “Trip Fuel” under
DIC Operation and Displays on page 3-46for more
information.
If your vehicle ever needs a new odometer installed,
the new one will be set to the correct mileage total of the
old odometer.
Tachometer
This gage indicates the engine speed in revolutions
per minute (rpm).
Engine Speed Limiter
This feature prevents the engine speed from reaching
an unsafe level. If the level is too high, the throttle closes
or limits the fuel supply until the engine speed returns
to a safe level. Throttle operation and fuel supply returns
to normal when engine speed is lowered.
Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, a chime sounds for
several seconds to remind the driver to fasten the
safety belt, unless the driver’s safety belt is already
buckled.
The driver safety belt light
comes on and stays on for
several seconds, then
ashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
safety belt is already buckled, neither the chime nor the
light comes on.
3-31

Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
sounds for several seconds to remind the front
passenger to buckle their safety belt. This only occurs
if the passenger airbag is enabled. SeePassenger
Sensing System on page 1-65for more information.
The passenger safety belt light, located on the
instrument panel, comes on and stays on for
several seconds and then ashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners,
the airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on
the airbag system, seeAirbag System on page 1-56.
The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.
3-32

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light in the instrument panel
cluster ever comes on and stays on, it means that
something may be wrong with the airbag system.
If this ever happens, have the vehicle serviced
promptly, because an adult-size person sitting in
the right front passenger’s seat may not have the
protection of the airbag(s). SeeAirbag Readiness
Light on page 3-32for more on this, including
important safety information.
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 3-51
for 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.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on,
the vehicle does not have antilock brakes and there is a
problem with the regular brakes. SeeBrake System
Warning Light on page 3-36.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-51for all
brake related DIC messages.
Traction Control System (TCS)
Warning Light
The traction control system
warning light comes on
briey while starting
the engine.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
This light comes on when your traction control system is
limiting wheel spin. You may feel or hear the system
working, but this is normal.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, the vehicle needs service. See
Traction Control System (TCS) on page 4-6for
more information.

when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. SeeEngine Overheating on page 5-29
for more information.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
It indicates when the engine has warmed up and if the
cooling system is operating properly. If the gage
pointer moves into the shaded area, the engine coolant
is too hot and the engine coolant temperature warning
light comes on. SeeEngine Overheating on page 5-29
for more information.

for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on,
but the engine is not
running, as a check to
show it working.
If it does not, have the vehicle serviced by your
dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
