are on.
. Two remote starts or a remote
start with an extension have
been used.
. The vehicle is not in P (Park). The engine will turn off during a
remote vehicle start if:
.
The coolant temperature gets
too high.
. The oil pressure gets low.
The RKE transmitter range may be
reduced while the vehicle is running.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System 013.

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
0 385 and
Tire Pressure Monitor Operation
0 386.
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 Oil0335.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended. See Maintenance

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 0337. 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 0385 and
Tire Pressure Monitor Operation
0 386.
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 SOON message
displays, the engine air filter should
be replaced at the earliest
convenience. The Air Filter Life display must be
reset after the engine air filter
replacement. To reset, see
Engine
Air Filter Life System 0339.
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
0 352.
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 Oil
For diesel engine vehicles, see
“Engine Oil” in the Duramax diesel
supplement.
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
. Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section. .
Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0337.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0328 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.

{Warning
Do not touch heater, radiator, a/c

parts. They can be very hot and
can burn you. Do not run the
engine if there is a leak; all
coolant could leak out. That could
(Continued)
Warning (Continued)
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine
coolant. This coolant is designed to
remain in the vehicle for 5 years or
240 000 km (150,000 mi), whichever
occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
seeEngine Overheating 0347.
What to Use
{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
(Continued)
Warning (Continued)
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
