This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
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. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center 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 you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.If the light stops flashing and remains on steady, see
ªIf the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You 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. See ªFilling Your Tankº in the Index. 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.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

2-74
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
See ªFilling Your Tankº in the Index. It will take a
few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
ªFuelº in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start
-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
CHECK ENGINE light is on or not working properly.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center
to prepare the vehicle for inspection.

2-78 Low Fuel Light
If the fuel level is low,
approximately one (3.8 L)
to two gallons (7.57 L) of
fuel remaining in the fuel
tank, a light will come on
until you add fuel.
The light may begin to flash as the fuel level gets lower.
It will also come on for a few seconds when you first
turn on the ignition as a check to show it's working.
If it doesn't come on then, have it fixed.
Fuel Cap Indicator Light
This light will come on
if the fuel cap has not
been fully tightened, is
missing or has been
improperly installed.
You should recheck your fuel cap to make sure it
is on tight.
If you continue to drive with a loose fuel cap, the
diagnostic system in your vehicle 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. If this happens, the CHECK
ENGINE light may come on. For more information, see
ªMalfunction Indicator Lampº earlier in this section.

Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire
-Loading Information label
found on the rear edge of the driver's door tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also gives you
important information about the number of people that
can be in your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight of all occupants, cargo and all
options not installed at the factory.
The other label is the certification label, found on the
rear edge of the driver's door. It tells you the gross
weight capacity of your vehicle, called the Gross
Vehicle Weight Rating (GVWR). The GVWR includes
the weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the
Gross Axle Weight Rating (GAWR) for either the front
or rear axle.
If you do have a heavy load, you should spread it out.
Don't carry more than 176 lbs. (80 kg) in the trunk.

Towing a Trailer
CAUTION:
If you don't use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull a trailer only if you have followed all the
steps in this section. Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº
that appears later in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That's the reason for this part. In it are many
time
-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load
-pulling components such as the engine,
transmission, rear axle, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. What's more, the trailer adds considerably to wind
resistance, increasing the pulling requirements.
