Engine Oil Life
System
When to Change
Engine Oil
This vehicle has a computer
system that indicates when to
change the engine oil and
filter. This is based on a
combination of factors which
include engine revolutions,
engine temperature, and miles
driven. Based on driving
conditions, the mileage at
which an oil change is
indicated can vary
considerably. For the oil life
system to work properly, the
system must be reset every
time the oil is changed.
When the system has
calculated that oil life has been
diminished, it indicates that an
oil change is necessary.
A CHANGE ENGINE OIL
SOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It ispossible that, if driving under
the best conditions, the oil life
system might indicate that an
oil change is not necessary for
up to a year. The engine oil
and filter must be changed at
least once a year and at this
time the system must be
reset. Your dealer has trained
service people who will
perform this work and reset
the system. It is also important
to check the oil regularly over
the course of an oil drain
interval and keep it at the
proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km
(3,000 mi) since the last oil
change. Remember to reset
the oil life system whenever
the oil is changed.
How to Reset the Engine
Oil Life System
Reset the system whenever
the engine oil is changed so
that the system can calculate
the next engine oil change. To
reset the system:
1. Using the DIC controls on the right side of the
steering wheel, display
REMAINING OIL LIFE on
the DIC. See Driver
Information Center (DIC)
0139. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press SEL on the DIC controls and hold SEL
down for a few seconds to
clear the CHANGE ENGINE
OIL SOON message and
reset the oil life at 100%.
Be careful not to reset the
oil life display accidentally
at any time other than
after the oil is changed.

What to Use
{Warning
Do not touch heater or
radiator hoses, or other
engine 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
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle.
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.
Caution
Do not use anything other
than a mix of DEX-COOL
coolant that meets GM
Standard GMW3420 and
clean, drinkable water.
Anything else can cause
damage to the engine
cooling system and the
vehicle, which would not be
covered by the vehicle
warranty.
Never dispose of engine
coolant by putting it in the
trash, pouring it on the
ground, or pouring into
sewers, streams, or bodies of
water. Have the coolant
changed by an authorized
service center, familiar with
legal requirements regarding
used coolant disposal. This will
help protect the environment
and your health.
Checking Coolant
The vehicle must be on a level
surface when checking the
coolant level.
Check to see if coolant is
visible in the coolant surge
tank. If the coolant inside the
coolant surge tank is boiling,
do not do anything else until it
cools down. If coolant is visible
but the coolant level mark is
not at or above the indicated
mark, add a 50/50 mixture of
clean, drinkable water and
DEX-COOL coolant. Be sure

Cleaning Underhood
Components
Caution
Do not power wash any
component under the hood
that has this
esymbol.
This could cause damage
that would not be covered
by the vehicle warranty.
Solvents or aggressive
cleaners may harm underhood
components. The usages of
these chemicals should be
avoided.
Recommend water only.
A pressure washer may be
used, but care must be utilized.
The following criteria must be
followed:
.Water pressure must be
kept below 14,000 KPa
(2,000 PSI).
.Water temperature must be
below 80 °C (180 °F).
.Spray nozzle with a
40 degree wide angle spray
pattern or wider must
be used.
.Nozzle must be kept at least
30 cm (1 ft) away from all
surfaces.
Finish Care
Application of aftermarket
clearcoat sealant/wax
materials is not recommended.
If painted surfaces are
damaged, see your dealer to
have the damage assessed
and repaired. Foreign
materials such as calcium
chloride and other salts, ice
melting agents, road oil and
tar, tree sap, bird droppings,
chemicals from industrial
chimneys, etc., can damage
the vehicle's finish if they
remain on painted surfaces.
Wash the vehicle as soon as
possible. If necessary, use
non-abrasive cleaners that are
marked safe for painted
surfaces to remove foreign
matter. Occasional hand waxing or
mild polishing should be done
to remove residue from the
paint finish. See your dealer
for approved cleaning
products.
Do not apply waxes or
polishes to uncoated plastic,
vinyl, rubber, decals, simulated
wood, or flat paint as damage
can occur.
Caution
Machine compounding or
aggressive polishing on a
basecoat/clearcoat paint
finish may damage it. Use
only non-abrasive waxes and
polishes that are made for a
basecoat/clearcoat paint
finish on the vehicle.
To keep the paint finish
looking new, keep the vehicle
garaged or covered whenever
possible.
