Anti-Lock Brake System Warning
Light
If your vehicle has an
anti-lock brake system, this
light will come on when the
ignition is turned to ON and
may stay on for several
seconds. That is normal.
If the light stays on, turn the ignition to LOCK. Or, if the
light comes on, 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 are driving, your vehicle needs service. If the
regular brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes. If the
regular brake system warning light is also on, you do
not have anti-lock brakes and there is a problem
with your regular brakes. SeeBrake System Warning
Light on page 3-30.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key to ON. This is
normal. If the light does not come on then, have it fixed
so it will be ready to warn you if there is a problem.
Speed Sensitive Power Steering
(SSPS) Warning Light
If your vehicle has Speed
Sensitive Power Steering
(SSPS), this warning
light will come on briefly
when you turn the ignition
to ON as a check to
show you it is working.
Then it should go out after a few seconds.
If the warning light does not come on, have it fixed so it
will be able to warn you if there is a problem.
If the warning light stays on, or comes on while you are
driving, the SSPS system may not be working. If this
happens, see your dealer for service.

This light will also come on during a malfunction in one
of two ways:
•Light Flashing— A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
•Reducing vehicle speed.
•Avoiding hard accelerations.
•Avoiding steep uphill grades.If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
flashing, follow the previous steps, and see your dealer
for service as soon as possible.
If the Light Is On Steady
You also may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling Your 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 will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.

Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Headlamp High/Low-Beam Changer” underTurn
Signal/Multifunction Lever on page 3-6for additional
information.
Daytime Running Lamps Indicator
Light
This light will come on
when the Daytime Running
Lamps (DRL) are on.
See “Daytime Running Lamps (DRL)” underExterior
Lamps on page 3-12for further information on the DRL
system.
Door Ajar Light
This light will stay on until
all doors are closed and
completely latched.
If the key is in the ignition while the driver’s door is
open, you will also hear a warning chime.

Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was
drinking and driving. In recent years, more than
16,000 annual motor vehicle-related deaths have been
associated with the use of alcohol, with more than
300,000 people injured.
Many adults — by some estimates, nearly half the adult
population — choose never to drink alcohol, so they
never drive after drinking. For persons under 21,
it is against the law in every U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for these laws.
The obvious way to eliminate the leading highway safety
problem is for people never to drink alcohol and then
drive. But what if people do? How much is “too much” if
someone plans to drive? It is a lot less than many might
think. Although it depends on each person and situation,
here is some general information on the problem.
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:
•The amount of alcohol consumed
•The drinker’s body weight
•The amount of food that is consumed before and
during drinking
•The length of time it has taken the drinker to
consume the alcohol.According to the American Medical Association, a
180 lb (82 kg) person who drinks three 12 ounce
(355 ml) bottles of beer in an hour will end up with a
BAC of about 0.06 percent. The person would reach the
same BAC by drinking three 4 ounce (120 ml) glasses
of wine or three mixed drinks if each had 1-1/2 ounces
(45 ml) of liquors like whiskey, gin or vodka.

Dinghy Towing
Notice:If you tow your vehicle with all four wheels
on the ground, the drivetrain components could
be damaged. The repairs would not be covered by
your warranty. Do not tow your vehicle with all
four wheels on the ground.
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
you should use a dolly. See “Dolly Towing” that follows
for more information.
Dolly Towing
Notice:Towing your vehicle from the rear with the
front wheels on the ground could cause transaxle
damage. Do not tow the vehicle from the rear
with the front wheels on the road.
Your vehicle can be towed using a dolly. To tow your
vehicle using a dolly, follow these steps:
1. Put the front wheels on a dolly.
2. Turn the ignition to ACC.
3. Put the vehicle in NEUTRAL.

Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward the
front of the engine compartment on the driver’s side
of the vehicle. SeeEngine Compartment Overview on
page 5-12for reservoir location.
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
Turn the key off and let the engine compartment cool
down. Then check the fluid level.
The level should be between the MIN (B) and MAX (A)
marks on the reservoir. If the level is below the
MIN (B) mark, add the power steering fluid to the
appropriate level. Replace the cap and completely
tighten it.

At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service
Lubricate all hood latch assemblies, secondary latch,
pivots, spring anchor, release pawl, hood and body door
hinges, rear compartment and any folding seat
hardware. Part D tells you what to use. More frequent
lubrication may be required when exposed to a corrosive
environment.
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-28if
necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transaxle vehicles, try to start the
engine in each gear. The starter should work only in
PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transaxle vehicles, put the shift lever in
NEUTRAL (N), push the clutch down halfway and try
to start the engine. The starter should work only
when the clutch is pushed down all the way to the
floor. If the starter works when the clutch is not
pushed all the way down, your vehicle needs service.
