When the ignition is on,
the fuel gage tells you
about how much fuel you
have remaining,
Here are four things that some owners ask about. None
of these show a problem with
your fuel gage:
At the gas station, the gas pump shuts off before the
gage reads
FULL (F).
It takes a little more or less fuel to fill up than the 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.

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time
to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is
it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness,
or whatever.
There is something about an easy stretch
of road with the
same scenery, along with the hum of the tires on the road,
the drone
of the engine, and the rush of the wind against
the vehicle that can make
you sleepy. Don’t let it happen
to you!
If it does, your vehicle can leave the road in less
than n second, and you could crash and be injured.
What can
you do about highway hypnosis‘? First, be
aware that it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to
the sides. Check your mirrors and your instruments
frequently.
If
you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway
as
an emergency.

The Certificationnire 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 Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
If you do have a heavy load, you should spread it out.

Downloaded from www.Manualslib.com manuals search engine Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood
to relieve pressure on the
hood prop.
Remove the hood prop
from the slot in the hood and
return the prop to
its retainer.
Then just pull the hood down firmly
to close. It will
latch when dropped from
10 to12 inches (25 to 30 cm)
without pressing
on the hood.
Engine Oil
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The oil dipstick is
a
yellow ring.
Turn
off the engine and
give the oil a few minutes
to drain back into the oil
pan.
If you don’t, the oil
dipstick might not show
the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or,
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD line, then you’ll
need to add some oil. But you must use the right kind.
This part explains what kind of
oil to use. For crankcase
capacity, see “Capacities and Specifications” in
the Index.

Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked when your tires are cold.
Overinflated tires are more likely
to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread
is badly worn, or if your tires have
been damaged, replace them.
Inflation - Tire Pressure
The Certificationmire label which is on the driver’s door
edge, above the door latch, shows the correct inflation
pressures for your tires
when they’re cold. “Cold”
means your vehicle has been sitting for
at least three
hours or driven
no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
Too much heat
0 Tire overloading
0 Bad wear
Bad handling
Bad fuel economy.
