GMC Sierra/Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-1500-11698638) - 2019 - crc - 5/15/18
28 In Brief
Fuel (Gasoline - L87 6.2L
Engine) Premium Recommended
Use premium 93 octane —
(R+M)/2 — unleaded gasoline in
your vehicle. TOP TIER Detergent
Gasoline is recommended.
Unleaded gasoline with an octane
rating as low as 87 may be used,
but it will reduce performance and
fuel economy.
See Recommended Fuel (Except
6.2L V8 Engine) 0 271 or
Recommended Fuel (6.2L
V8 Engine) 0 271 .
Fuel (Diesel) For diesel vehicles, do not use
gasoline. See “ Fuel for Diesel
Engines ” in the Duramax diesel
supplement. E85 or FlexFuel FlexFuel Possible
Certain models are compatible with
E85 fuel. See E85 or FlexFuel
0 272 .
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:
1. Display the oil life percentage
on the DIC. See Driver Information Center
(DIC) (Midlevel and Uplevel)
0 160 or Driver Information
Center (DIC) (Base Level)
0 159 .
2. Press the thumbwheel on the
steering wheel, or the trip
odometer reset stem if the
vehicle does not have DIC
controls, for several seconds.
When the confirmation
message displays, select YES.
The oil life will change
to 100%.
The oil life system can also be reset
as follows:
1. Display the oil life percentage
on the DIC.
See Driver Information Center
(DIC) (Midlevel and Uplevel)
0 160 or Driver Information
Center (DIC) (Base Level)
0 159 .
2. Fully press the accelerator
pedal slowly three times within
five seconds.
3. If the display changes to 100%,
the system is reset.

vehicle systems. The trip odometer
reset stem in the instrument cluster
is used to access the DIC menu
items.
If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.

Units
Digital Speedometer
The speedometer shows how fast
the vehicle is moving in either
kilometers per hour (km/h) or miles
per hour (mph). The speedometer
cannot be reset.
Trip 1 or 2 and Average Fuel
Economy
Turn the trip odometer reset stem
until TRIP 1 or TRIP 2 displays. The
current distance traveled, in either
kilometers (km) or miles (mi), since
the last reset for the trip odometer is
shown, as well as the average fuel
economy. The trip odometer and the
average fuel economy can be reset
by pressing and holding the trip
odometer reset stem.
Fuel Range
This display shows the approximate
distance the vehicle can be driven
without refueling. The fuel range
estimate is based on an average of
the vehicle's fuel economy over recent driving history and the
amount of fuel remaining in the fuel
tank. Fuel range cannot be reset.
Tire Pressure
Turn the trip odometer reset stem
until a vehicle with the approximate
pressures of all four tires displays.
Tire pressure is displayed in either
kilopascal (kPa) or in pounds per
square inch (psi).
See Tire Pressure Monitor System
0 369 and Tire Pressure Monitor
Operation 0 370 .
Remaining Oil Life
Turn the trip odometer reset stem
until REMAINING OIL LIFE
displays. An estimate of the oil's
remaining useful life is shown.
REMAINING OIL LIFE 99% means
99% of the current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. See Engine Oil 0 321 .
In addition to the engine oil life
system monitoring the oil life,

Mexico-1500-11698638) - 2019 - crc - 5/15/18
162 Instruments and Controls In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended. See Maintenance
Schedule 0 415 .
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life
display at any time other than when
the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, press the
thumbwheel while the Oil Life
display is active. See Engine Oil
Life System 0 323 .
Tire Pressure : Shows the
approximate pressures of all four
tires. Tire pressure is displayed in
either kilopascal (kPa) or in pounds
per square inch (psi). If the pressure
is low, the value for that tire is
shown in amber.
See Tire Pressure Monitor System
0 369 and Tire Pressure Monitor
Operation 0 370 .
Air Filter Life : Shows an estimate
of the engine air filter ’ s remaining
useful life and the state of the system. Engine Air Filter Life 95%
means 95% of the current air filter
life remains. Messages will display
based on the engine air filter life and
the state of the system. When the
REPLACE AT NEXT OIL CHANGE
message displays, the engine air
filter should be replaced at the time
of the next oil change. When the
REPLACE NOW message displays,
the engine air filter should be
replaced as soon as possible.
The Air Filter Life display must be
reset after the engine air filter
replacement. To reset, see Engine
Air Filter Life System 0 325 .
Brake Pad Life : This displays an
estimate of the remaining life of the
front and rear brake pads.
Messages will display based on
brake pad wear and the state of the
system. Reset the Brake Pad Life
display after replacing the brake
pads. See Brake Pad Life System
0 335 . Fuel Economy : Displays average
fuel economy, the best fuel
economy over the selected
distance, and a bar graph showing
instantaneous fuel economy.
Press the thumbwheel to change
the selected distance. Press and
hold the thumbwheel while this
display is active to reset the best
fuel economy and average fuel
economy. This display can also be
reset by selecting reset in the menu.
Engine Hours (Hourmeter) :
Shows the total number of hours the
engine has run. This display also
shows the engine idle hours.
Transmission Fluid
Temperature : Shows the
temperature of the automatic
transmission fluid in either degrees
Celsius (°C) or degrees
Fahrenheit (°F).

Engine Oil Change When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and filter must be changed at least once
a year and the oil life system must
be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
See Engine Oil Life System 0 323 .
Passenger Compartment Air
Filter The passenger compartment air
filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
Inspect the passenger compartment
air filter every 36 000 km/
22,500 miles or two years,
whichever comes first. Replace if
necessary. More frequent
replacement may be needed if the
vehicle is driven in areas with heavy
traffic, areas with poor air quality,
or areas with high dust levels. Replacement may also be needed if
there is a reduction in air flow,
excessive window fogging, or odors.
Extended Idle Use When the vehicle is used in a way
that requires extended idle time,
one hour of use shall be deemed
the same as 53 km (33 mi).
See Driver Information Center (DIC)
(Midlevel and Uplevel) 0 160 or
Driver Information Center (DIC)
(Base Level) 0 159 for hourmeter.
Air Conditioning Desiccant
(Replace Every Seven Years) The air conditioning system requires
maintenance every seven years.
This service requires replacement of
the desiccant to help the longevity
and efficient operation of the air
conditioning system. This service
can be complex. See your dealer.

(3) Visually check all fuel and vapor
lines and hoses for proper
attachment, connection, routing, and
condition.
(4) Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water
can overcome the seals and contaminate the fluid. Contaminated
fluid will decrease the life of the
transfer case and/or drive axles and
should be replaced.
(5) Or every five years, whichever
