b I
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
0 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 “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 drive the vehicle
to your
dealer or qualified service center for service.
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. 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.
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. It
will take a few driving trips to turn the light off.

FUEL ONLY UNLEADED
The
fuel gage, when the
ignition is
on, tells you
about how much fuel you
have left in your tank. Listed are
four situations you may experience with your
fuel gage:
At the gas station, the fuel pump shuts off before the
gage reads FULL
(F).
It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may have
indicated the tank was half full, but
it actually took a
little more or less than half the tank's capacity
to fill
the tank.
The gage moves a little when you turn a corner or
speed up.
The gage will first indicate EMPTY
(E) before you
are out of fuel, and you should get more fuel as soon
as possible.
The gage doesn't go back to EMPTY (E) when you
turn off the ignition.
None
of these indicate a problem with the fuel gage.

COLD TIRE PRESSURE
The Certificationrnire label is found on the rear edge of
the driver's door. The label shows the size
of your
original tires and the inflation pressures needed to obtain
the gross weight capacity of your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel
and cargo. The
Certificatioflire label also tells you the maximum
weights for the front and rear axles, called
Gross Axle
Weight Rating (GAWR).
To find out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with
this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR
for either the front or rear axle.
And, if you do have a heavy load, you should spread
it out.
I
I
A QUI 0 :
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can break,
or
it can change the way your vehicle handles.
These could cause you to lose control.
Also,
overloading can shorten the life of your vehicle.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your dealer for important information about towing a trailer
with your vehicle.
Your vehicle can tow a trailer. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in “Weight of the Trailer”
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 section. 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.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer will
weigh
4,000 lbs. (1 800 kg) or less. You should
always use a sway control
if your trailer will weigh
more than
4,000 lbs. (1 800 kg). You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 kmh) and
don’t make starts
at full throttle. This helps your
engine and other parts of your vehicle wear
in at the
heavier loads.

If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel wouldn’t be
covered by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
YOU can also write us at the following address for
advice.
Just tell us where you’re going and give your

Filling Your Tank (Gasoline Engine)
If your vehicle has a diesel engine, see “Filling Your
Tank (“Diesel Engine)” in the Diesel Engine Supplement.
11 The fuel cap is behind a
hinged door on the driver’s
side of your vehicle.
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

Downloaded from www.Manualslib.com manuals search engine While refueling your
vehicle, hang the cap by
the tether from the hook
on the filler door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if
you let
go of the cap too soon, it will spring back
to the right.
A CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out
on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the way.
Be careful
not to spill gasoline. Clean gasoline from
painted surfaces as
soon as possible. See “Cleaning
the Outside
of Your Vehicle” in the Index.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure
you fully install the cap. The diagnostic system
can determine if the fuel
cap has been left off or
improperly installed. This would allow
fuel to
evaporate into the atmosphere. See “Malfunction
Indicator Lamp” in the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
Filling a Portable Fuel Container
/i CAUTIOlr:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor.
You can
be badly burned and your vehicle damaged if this
occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
