The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airow or tail pipes).
The exhaust smells or
sounds strange or different.
The exhaust system leaks
due to corrosion or damage.
(Continued)
CAUTION (Continued)
The vehicle’s exhaust system
has been modied, damaged
or improperly repaired.
There are holes or openings
in the vehicle body from
damage or after-market
modications that are not
completely sealed.
If unusual fumes are detected or if
it is suspected that exhaust is
coming into the vehicle:
Drive it only with the windows
completely down.
Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.

Running the Vehicle
While Parked
It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{CAUTION
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation.
For more information, seeEngine
Exhaust on page 2-31.
{CAUTION
It can be dangerous to get out
of the vehicle if the automatic
transmission shift lever is not fully
in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you have
to. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when it is on
fairly level ground, always set
the parking brake and move the
automatic transmission shift lever
to P (Park), or the manual
transmission shift lever to Neutral.Follow the proper steps to be
sure the vehicle will not move.

glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror’s surface
is curved so more can be seen from
the driver seat.

If the warning light comes on, there
could be a brake problem. Have
the brake system inspected
right away.
This light comes on briey when the
ignition key is turned to ON/RUN.
If it does not, have it xed so it
will be ready to warn if there is a
problem.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set. See
Parking Brake on page 2-28for
more information. The light stays on
if the parking brake does not
release fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or
it might go closer to the oor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing Your Vehicle
on page 4-40.
{CAUTION
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning
light on can lead to a crash. If the
light is still on after the vehicle
has been pulled off the road and
carefully stopped, have the
vehicle towed for service.
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 will then go 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 United States

the vehicle’s fuel economy might
not be as good, and the engine
might not run as smoothly.
This could lead to costly repairs
that might not be covered by
the vehicle warranty.
Notice:Modications made to
the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle’s emission
controls and can cause this light
to come on. Modications to
these systems could lead
to costly repairs not covered by
the vehicle warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
on page 5-3.This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when
it is safe to do so, stop the
vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still ashing,
follow the previous steps and
see your dealer/retailer for service
as soon as possible.Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-7. 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
the light off.
If the vehicle has been driven
through a deep puddle of
water, the vehicle’s electrical
system might be wet. The
condition is usually corrected
when the electrical system dries
out. A few driving trips should
turn the light off.
