Cooling System
It is not necessary to regularly check coolant
unless a leak is suspected or an unusual
noise is heard. A coolant loss could indicate
a problem. Have it inspected and repaired
by your dealer.
The following explains the cooling system
and how to check coolant level.
During vehicle operation and also during
charging, the high voltage battery cells in
the vehicle are kept within a normal
operating temperature range. If the
temperature rises above this temperature, the battery cooling system turns on the air
conditioning compressor and cools the
coolant until the correct temperature is
reached. If the temperature falls below this
temperature, a high voltage heater, located
outside the battery on a cradle, heats the
coolant until the correct temperature is
reached.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See
Maintenance
Schedule 0389.
The coolant reservoir is in the underhood
compartment. See Underhood Compartment
Overview 0325.
To access the coolant reservoir under the
hood, the right side access cover needs to
be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood019.
3. Turn the three bolts three quarter turn
and remove the right side access cover.

4. After the system has completely cooled,check that the coolant level in the
reservoir.
5. If the coolant level is not visible or needsto be adjusted within the reservoir,
contact your dealer.
Washer Fluid
What to Use
When windshield washer fluid is needed, be
sure to read the manufacturer's instructions
before use. If operating the vehicle in an
area where the temperature may fall below
freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol on it.
Add washer fluid until the tank is full. See
Underhood Compartment Overview 0325 for
reservoir location.
Caution
.Do not use washer fluid that contains
any type of water repellent coating.
This can cause the wiper blades to
chatter or skip.
.Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
.Do not mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage the
washer fluid tank and other parts of
the washer system.
(Continued)
Caution (Continued)
.When using concentrated washer fluid,
follow the manufacturer instructions
for adding water.
.Fill the washer fluid tank only
three-quarters full when it is very cold.
This allows for fluid expansion if
freezing occurs, which could damage
the tank if it is completely full.
Brakes
Disc brake linings have built-in wear
indicators that make a high-pitched warning
sound when the brake linings are worn and
new linings are needed. The sound can come
and go or can be heard all the time when
the vehicle is moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning sound means
that soon the brakes will not work well.
That could lead to a crash. When the
brake wear warning sound is heard, have
the vehicle serviced.

Own Service Work 0324.
Maintenance Schedule
Rotate Tires and Perform 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 0357 and
Wheel Replacement 0360.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 390.
.Lubricate body components. See Exterior
Care 0379.
Additional Required Services —Normal
Service
Every 36 000 km (22,500 mi)

traffic, poor air quality, high dust levels,
or environmental allergens. Passenger

also be needed if there is reduced airflow,
window fogging, or odors. Your GM
dealer can help determine when to
replace the filter. Every 161 000 km (100,000 mi)
