Getting to Know Your Sierra22
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they’re cold. “Cold” means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily clear the DIC
message by acknowledging it with
your DIC controls. However, at the next
vehicle start-up, the DIC message will
reappear if the tire pressure has not
been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.
Note:The Tire Pressure Monitor can
alert you about low tire pressure, but it
doesn’t replace normal monthly tire
maintenance.
Integrated Trailer Brake Control
System (if equipped)
The control
panel for the
Integrated
Trailer Brake
Control (ITBC)
system is locat-
ed on the
instrument
panel to the left of the steering wheel.If the Tighten Gas Cap message is
displayed on the Driver Information
Center (DIC), check that your fuel cap
is properly installed. If the cap is not
securely fastened, turn it clockwise until
a clicking sound is heard, indicating that
it is properly installed. The DIC message
will turn off after a few driving trips with
the cap properly installed.
See Sections 3 and 5 of your Owner Manual.
Tighten Gas Cap Message
If your vehicle has a yellow gas cap, it
was engineered as a FlexFuel vehicle
capable of running on gasoline or E85
fuel. E85 is a blend of 85% ethanol and
15% gasoline. E85 is a high-octane,
renewable fuel made primarily from corn
(see livegreengoyellow.com).
