Filling The Tank - GMC Sierra Denali 2014 Owner's Manual

Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
That damage would not be
covered under the vehicle
warranty.

Filling the Tank

If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
To help avoid injuries to you
and others, read and follow
all the instructions on the fuel
pump island.
Warning (Continued)
Turn off the engine when
refueling.
Keep sparks, flames, and
smoking materials away
from fuel.
Do not leave the fuel pump
unattended.
Do not reenter the vehicle
while pumping fuel.
Keep children away from the
fuel pump and never let
children pump fuel.
Fuel can spray out if the fuel
cap is opened too quickly.
This spray can happen if the
tank is nearly full, and is
more likely in hot weather.
Open the fuel cap slowly and
wait for any hiss noise to stop
then unscrew the cap all
the way.

Driving and Operating
The fuel cap is behind a hinged fuel
door on the driver side of the
vehicle. Vehicles that have a
FlexFuel badge and a yellow fuel
cap can use either unleaded
gasoline or ethanol fuel containing
up to 85% ethanol (E85). See E85
or FlexFuel on page 9-64.
To remove the fuel cap, turn it
slowly counterclockwise.
If the vehicle is a dual fuel tank
chassis cab model, and it runs out
of fuel, refuel the front fuel tank first
to ensure a quick restart.
