1998 GMC SIERRA fuel cap

~ Be
careful not to spill gasoline. Clean gasoline from
~ painted surfaces as soon as possible. See “Cleaning the
i Outside of Your Vehicle” in the Index.
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 ‘LMalfunction Indicator Lamp” in
the Index.
Filling a Portable Fuel Container
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.
