Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑15.
The warning light will remain on until
the tire pressure is corrected.

Black plate (32,1)GMC Sierra Owner Manual - 2013 - crc - 8/14/12
1-32 In Brief
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
SeeTire Pressure Monitor System
on page 10‑57.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change. Resetting the Oil Life System
To reset the Engine Oil Life System
on most vehicles:
1. Display OIL LIFE REMAINING
on the DIC. If the vehicle does
not have DIC buttons, the
vehicle must be in P (Park) to
access this display.
2. Press and hold the SET/RESET button on the DIC, or the trip
odometer reset stem if the
vehicle does not have DIC
buttons, for more than
five seconds. The oil life will
change to 100%.
On all vehicles, the Engine Oil Life
System can be reset as follows:
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press the accelerator pedal slowly three times within
five seconds. 3. Display OIL LIFE REMAINING
on the DIC. If the display shows
100%, the system is reset.
See Engine Oil Life System on
page 10‑9.
Fuel E85 (85% Ethanol)
Vehicles that have a yellow fuel cap
can use either unleaded gasoline or
ethanol fuel containing up to 85%
ethanol (E85). See Fuel E85 (85%
Ethanol) on page 9‑68. For all other
vehicles, use only the unleaded
gasoline described under
Recommended Fuel on page 9‑66.

2-6 Keys, Doors, and Windows
For example, ifQand then/are
pressed again after the vehicle has
been running for five minutes,
10 minutes are added, allowing the
engine to run for 15 minutes.
The additional 10 minutes are
considered a second remote vehicle
start.
Once two remote starts, or a single
remote start with one time extension
has been done, the vehicle must be
started with the key. After the key is
removed from the ignition, the
vehicle can be remote started again.
The vehicle cannot be remote
started if the key is in the ignition,
the hood is not closed, or if there is
an emission control system
malfunction and the check engine
light is on.
Also, the engine will turn off during a
remote vehicle start if the coolant
temperature gets too high or if the
oil pressure gets low.Remote Start Ready
If the vehicle does not have the
remote vehicle start feature, it may
have the remote start ready feature.
This feature allows your dealer to
add the manufacturer's remote
vehicle start feature.
See your dealer to add the
manufacturer's remote vehicle start
feature to the vehicle.
Door Locks
{WARNING
Unlocked doors can be
dangerous.
.Passengers, especially
children, can easily open the
doors and fall out of a moving
vehicle. When a door is
locked, the handle will not
open it. The chance of being
thrown out of the vehicle in a
crash is increased if the
(Continued)
WARNING (Continued)
doors are not locked. So, all
passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.
.Young children who get into
unlocked vehicles may be
unable to get out. A child can
be overcome by extreme heat
and can suffer permanent
injuries or even death from
heat stroke. Always lock the
vehicle whenever leaving it.
.Outsiders can easily enter
through an unlocked door
when you slow down or stop
the vehicle. Locking the doors
can help prevent this from
happening.
There are several ways to lock and
unlock the vehicle.

Seats and Restraints 3-13
.Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{WARNING
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
If the vehicle is a regular cab, then
all seating positions in the vehicle
have a lap-shoulder belt. If the
vehicle is a crew or extended cab,
then all seating positions in the
vehicle have a lap-shoulder belt
except for the center front
passenger position (if equipped),
which has a lap belt. SeeLap Belt
(Crew and Extended Cab) on
page 3‑18 for more information.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index. 2. Pick up the latch plate and pull
the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
Engaging the child restraint
locking feature may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System on page 3‑31
for more information.

Seats and Restraints 3-19
To make the belt shorter, pull its free
end as shown until the belt is snug.
If the belt is not long enough, see
Safety Belt Extender on page 3‑19.
Make sure the release button on the
buckle is positioned so you would
be able to unbuckle the safety belt
quickly if necessary.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working properly.Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer
to have it repaired. Torn or frayed
safety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. See
Safety Belt
Reminders on page 5‑16.
Keep safety belts clean and dry.
See Safety Belt Care on page 3‑19.
Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.

crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as

have been stressed or damaged.
See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.

checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
