1996 CHEVROLET EXPRESS fuel type

Downloaded from www.Manualslib.com manuals search engine If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp
on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized GM dealer for diagnosis to determine the
cause
of hilure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may
not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp
on your instrument
panel
may turn on. If this happens, return to your
authorized GM dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should
not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available
in your area to help clean the air. General
Motors recommends that
you use these gasolines if they
comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it.
It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right until
you hear at least three clicks. 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.
I 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 or have proper
venting, and your fuel tank and emissions system
might
be damaged.
Checking Things Under the Hood
To open the hood, first pull
this handle inside the
vehicle. It is just in front of
the driver’s side
door frame
near the floor.

Downloaded from www.Manualslib.com manuals search engine Inflation -- Tire Pressure
The Certificationflire label, which is on the rear edge of
the driver’s door, 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 1 mile (1.6 km).
I 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 junderinflation), you can
get the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued)
I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
