The vehicle can tow in
D (Drive). Shift the
transmission to a lower gear if
the transmission shifts too
often under heavy loads and/
or hilly conditions.
When towing at higher
altitudes, engine coolant will
boil at a lower temperature
than at lower altitudes. If the
engine is turned off
immediately after towing at
high altitude on steep uphill
grades, the vehicle could show
signs similar to engine
overheating. To avoid this, let
the engine run, preferably on
level ground, with the
transmission in P (Park) for a
few minutes before turning
the engine off. If the overheat
warning comes on, see Engine
Overheating0342.Parking on Hills
{Warning
To prevent serious injury or
death, always park your
vehicle and trailer on a level
surface when possible.
When parking your vehicle and
your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into
the curb if facing downhill
or into traffic if facing
uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, gradually
release the brake pedal to
allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking
brake and shift into
P (Park). 5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake
pedal.
.Start the engine.
.Shift into the
desired gear.
.Release the parking
brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer
Towing
The vehicle needs service
more often when used to tow
trailers. See Maintenance
Schedule 0425. It is especially
important to check the
automatic transmission fluid,
engine oil, axle lubricant, belts,

bodies of water. Recycle it by
taking it to a place that
collects used oil.
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 OILSOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It is
possible that, if driving under
the best conditions, the oil life
system may 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)
0136. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press
Von the DIC
controls and hold 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.

{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.
Engine Coolant
The engine cooling system in
the vehicle is filled with
DEX-COOL engine coolant
mixture. This coolant needs to
be checked and changed at
appropriate levels. See
Recommended Fluids and
Lubricants0429 and
Maintenance Schedule 0425.
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, see
Engine Overheating 0342.
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.

Vehicle Care 413
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 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, birddroppings, 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
(Continued)
Caution (Continued)
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.
Protecting Exterior Bright
Metal Moldings
Caution
Failure to clean and protect
the bright metal moldings
can result in a hazy white
finish or pitting. This damage
would not be covered by the
vehicle warranty.
The bright metal moldings on
the vehicle are aluminum,
chrome, or stainless steel. To
prevent damage always follow
these cleaning instructions:
.Be sure the molding is cool
to the touch before applying
any cleaning solution.
