Filling Your Tank
1
A CAUTION:
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.
The cap is behind a hinged door on the left side of your
vehicle.
To take
off the cap, turn it slowly to the left
(counterclockwise).
If you get gasoline on you 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.
When you put the cap back on, turn it to the right until
you hear a clicking
noise.

When to Change Engine Oil: See if any one of these is
true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less than
10 miles (16 km).
The engine is at low speed most of the time (as in
door-to-door delivery,
or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your vehicle, then you need
to change your oil and filter every 3,000 miles
(5 O00 km) or 3 months-whichever comes first.
If none
of them is true, change the oil every 7,500 miles
(12 500 km) or 12 months-whichever comes first.
Change the fdter at the first oil change and at every other
oil change afier that.
Engine Block Heater: An engine block heater can be a
big help if you have to park outside
in very cold weather,
0°F (-18°C) or colder. If your vehicle has this option, see
“Engine Block Heater”
in the Index.
What to Do with Used Oil:
-
/i CAUTION:
Used engine oil contains things that have
caused skin cancer in laboratory animals.
Don’t let used oil stay on your skin for very
long. Clean your skin and nails with soap and
water or a good hand cleaner. Wash or
properly throw away clothing or rags
containing used engine oil.
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by pouring it on the ground, into sewers, or into streams
or bodies of water. Instead, recycle it ‘by taking
it to a
place that collects used
oil. If you have a problem
properly disposing of your used oil, ask your dealer, a
service station or a local recycling center for help.
