{Warning
An underhood electric fan can start up
even when the engine is not running and
can cause injury. Keep hands, clothing,
and tools away from any underhood
electric fan.
{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 cooling system in the vehicle is filled
with DEX-COOL engine coolant. This coolant
is designed to remain in the vehicle for five
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, see
Engine Overheating 0264.
What to Use
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With 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.

262 Vehicle Care
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 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.
It is normal to see coolant moving in the
upper coolant hose return line when the
engine is running.
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 is
not at or above the mark pointed to, add a
50/50 mixture of clean drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool before
this is done.
If no coolant is visible in the coolant surge
tank, add coolant as follows:
How to Add Coolant to the Coolant
Surge Tank
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With 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.

Appearance Care
Exterior Care
Locks
Locks are lubricated at the factory. Use a
de-icing agent only when absolutely
necessary, and have the locks greased after
using. SeeRecommended Fluids and
Lubricants 0327.
Washing the Vehicle
To preserve the vehicle's finish, wash it
often and out of direct sunlight.
Caution
Do not use petroleum-based, acidic,
or abrasive cleaning agents as they can
damage the vehicle's paint, metal,
or plastic parts. If damage occurs, it
would not be covered by the vehicle
warranty. Approved cleaning products can
be obtained from your dealer. Follow all
manufacturer directions regarding correct
product usage, necessary safety
precautions, and appropriate disposal of
any vehicle care product.
Caution
Avoid using high-pressure washes closer
than 30 cm (12 in) to the surface of the
vehicle. Use of power washers exceeding
8 274 kPa (1,200 psi) can result in
damage or removal of paint and decals.
If using an automatic car wash, follow the
car wash instructions. The windshield wiper
and rear window wiper, if equipped, must
be off. Remove any accessories that may be
damaged or interfere with the car wash
equipment.
Rinse the vehicle well, before washing and
after, to remove all cleaning agents
completely. If they are allowed to dry on
the surface, they could stain.
Dry the finish with a soft, clean chamois or
an all-cotton towel to avoid surface
scratches and water spotting.
Cleaning Underhood Components
Caution
Do not power wash any component
under the hood that has this
e
symbol.(Continued)
Caution (Continued)
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,

instructions on the label. While cleaning the
interior, open the doors and windows to get
proper ventilation. Newspapers or dark
garments can transfer color to the vehicle’s
interior.
Caution
Immediately remove cleaners, hand
lotions, sunscreen, and insect repellent
from all interior surfaces or permanent
damage may result.
Caution
Use cleaners specifically designed for the
surfaces being cleaned to prevent
permanent damage to the vehicle. Apply
all cleaners directly to a cleaning cloth.
Do not spray cleaners on any switches or
controls.
When using liquid soap cleaners, follow the
directions on the specific cleaner or soap
solution for dilution instructions.
Caution
To prevent damage:
.Never use a razor or any other sharp
object to remove soil from any interior
surface
.Never use a brush with stiff bristles.
.Never rub any surface aggressively or
with too much pressure.
.Do not get any exposed electrical
components wet.
.Do not use laundry detergents or
dishwashing soaps with degreasers. Do
not use solutions that contain strong
or caustic soap.
.Do not heavily saturate the upholstery
when cleaning.
.Do not use solvents or cleaners
containing solvents.
.Do not use disinfecting wipes that are
scented or contain bleach. Do not use
wipes or cleaners that show a color

appearance of the interior surface
when used.
(Continued)
Caution (Continued)
.Do not use scented or gel-type hand
sanitizers. If hand sanitizer comes in
contact with interior surfaces of the
vehicle, blot immediately and clean
with a soft cloth dampened with a
mild soap and water solution.
Interior Glass
To clean, use a microfiber cloth fabric
dampened with water. Wipe droplets left
behind with a clean dry cloth. If necessary,
use a commercial glass cleaner after
cleaning with plain water.
Caution
To prevent scratching, never use abrasive
cleaners on automotive glass. Abrasive
cleaners or aggressive cleaning may
damage the rear window defogger.
Cleaning the windshield with water during
the first three to six months of ownership
will reduce tendency to fog.

Maintenance Schedule
Tire Rotation and Required Services
Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform
wear for all tires. The first rotation is the
most important.
Anytime unusual wear is noticed, rotate the
tires as soon as possible, check for proper
tire inflation pressure, and check for
damaged tires or wheels. If the unusual
wear continues after the rotation, check the wheel alignment. See
When It Is Time for
New Tires 0297 and
Wheel Replacement 0301.
