Running Your Engine While You’re
Parked (Automatic Transaxle)
It’s better not to park with the engine running. But if you
ever have to, here are some things to know.
I-
A CAUTION:
-
Idling the engine with the climate control
system
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in
a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust -- with
CO -- can come in easily. NEVER park in a .
garage with the engine running.
Another closed-in place can be
a blizzard.
(See “Blizzard” in the Index.)
A CAUTION:
-1
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly
set. Your vehicle can roll.
Don’t leave your vehicle when the engine
is
running unless you have to. If you’ve left the
engine running, the vehicle can move suddenly.
You
or others could be injured. To be sure your
vehicle won’t move, even when you’re
on fairly
level ground, always set your parking brake and
move the shift lever
to PARK (P).
Follow the proper steps to be sure your vehicle won’t
move. See “Shifting Into
PARK (P)” in the Index.
If you are parking on a hill and if you’re pulling a
trailer,
also see “Towing a Trailer” in the Index.

Daytime Running Lamps
Daytime Running Lamps (Dm) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short periods after dawn and before sunset.
The
DRL system will make your high-beam headlamps
come on at a reduced brightness when:
0 The engine is running,
0 The headlamp switch is OFF,
The light sensor detects daytime light,
The parking brake is released and
The shift lever is not in PARK (P) on an
When the DRL system is on, the taillamps, sidemarker,
parking lamps and instrument panel lights will not
be illuminated. automatic transaxle.
The
DIU and ALC systems will remain off any time
your automatic transaxle vehicle is
in Park (P) and the
parking brake is engaged.
The
DFU and ALC systems will remain off any time
your manual transaxle vehicle is in Neutral
(N) and the
parking brake is engaged.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Light Control (ALC)
Your vehicle is equipped with an automatic light sensor
on top of the instrument panel under the defroster
grin,
so be sure it is not covered which will cause the
nighttime lights to be on continuously.
When it is dark enough outside,
your ALC will turn on
your headlamps that you were last using at the normal
brightness along with other lamps such as the taillamps,
sidemarker, parking lamps and instrument panel lights.
There is a 20-second delay in the transition between
daytime and nighttime operation
of the DRL and LC
systems. If the light sensor senses a reduction in lighting
that lasts longer than 20-seconds, it will activate the
nighttime lamps. If you are driving through a parking
garage, heavy overcast weather, a tunnel or fueling your
vehicle in a low light area, the
ALC will turn on your
low-beam headlamps at a normal brightness along with
the taillamps, sidemarker lamps, parking lamps and the
instrument panel lights. The radio lights will be dimmer.
As with any vehicle, you should turn on the regular
headlamp system when you need
it.

Tachometer
si The tachometer shows your
1 engine speed in revolutions
per minute (rpm).
NOTICE:
Do not run your engine at speeds in the red area,
or engine damage may occur. I
Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them. 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
your warning lights
and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem
with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come
on briefly when you start the
engine just to let you
know they’re working. If you are
familiar with this section, you should not
be alarmed
when
this happens.
Gages can indicate when there may be or is
a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.
When one
of the warning lights comes on and stays on
when you are driving,
or when one of the gages shows
there may
be a problem, check the section that tells you
what to do about
it. Please follow this manual’s advice.
Waiting
to do repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come
on and stay on
for about 20 seconds,
then it will flash for about
55 seconds.
If the driver’s belt is already buckled, neither the chime
nor
the light will come on.
AIR
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR
BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensor, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the
air bag system, see “Air
Bag” in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your
air bag
system may not work properly. Have your vehicle
serviced right away.
The
air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the
light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.

Charging System Indicator Light
~ The charging system
indicator light will come
on
briefly when you turn on the
ignition, but the engine is
not
running. The light will
go out when the engine
is started.
If it stays on when your engine is running, or comes on
while you are driving, you may have a problem with the
electrical charging
system. It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. Driving while
this
light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need
both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
BRAKE

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may
go closer to the floor.
It may take longer to stop. If the light
is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
I A CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead to an accident.
If the light is still on after you’ve
pulled off the road and stopped carefully, bqve
the vehicle towed for service.
When the ignition is on, the brake system warning light
will
also come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully.
If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system,
this light will come
on when you
start your
engine
and it will stay on
for three seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop
as soon as
possible and turn the ignition off. Then start the engine
again to reset the system.
If the light still stays on, or
comes on
again while you’re driving, your vehicle needs
service. If the regular brake system warning light isn’t
on, you still have brakes, but you don’t have anti-lock
brakes.
If the regular brake system warning light is also
on, you don’t have anti-lock brakes and there’s a
problem with
your regular brakes. See “Brake System
Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready
to warn you if there is a problem.

CHECK
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
If there are visible signs of steam see “Engine
Overheating’’
in the Index before opening the hood.
Have your vehicle serviced as soon
as you can.
This system is called OBD 11 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate that there is a problem
and service is required.
Malfunctions often will be indicated by the system
before any problem
is apparent. This may prevent more
serious damage to
your vehicle. This system is also
designed to assist your service technician
in correctly
diagnosing
any malfunction.
