1. Retaining Clips
2. Air Duct Clamp
3. Electrical Connector
To inspect or replace the air filter:1. Open the hood. See Hood 0240.
2. Locate the engine air cleaner/ filter assembly on the
passenger side of the engine
compartment. See Engine
Compartment Overview 0242.
3. Disconnect the air duct by loosening the air duct
clamp (2).
4. Disconnect the electrical connector (3). 5. Lift the retaining clips (1) from
the engine air cleaner/filter
assembly.
6. Turn and tilt the air cleaner/ filter cover slightly upward and
slide it out. Remove the air
cleaner/filter.
How to Reinstall the Engine
Air Cleaner/Filter
1. Install the air filter into theengine air cleaner/filter
assembly. The outer air filter
seal must be fitted properly in
the engine air cleaner/filter
assembly.
2. Replace the air cleaner/filter cover by lowering it to meet the
bottom of the engine air
cleaner/filter assembly. Place
the retaining clips (1) on the
engine air cleaner/filter
assembly and secure. The rear
tabs must be secured into the
lower portion of the air cleaner/
filter.
3. Reconnect the air duct and tighten the air duct clamp (2). 4. Reconnect the electrical
connector (3).
{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.

Vehicle Care 255
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or if parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir
is filled with GM approved DOT 3
brake fluid as indicated on the
reservoir cap. SeeEngine
Compartment Overview 0242 for
the location of the reservoir. Checking Brake Fluid
With the vehicle in P (Park) on a
level surface, the brake fluid level
should be between the minimum
and maximum marks on the brake
fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.
Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light 0114.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid
at the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0318.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0327.

Vehicle Care 257
Keep the vehicle plugged in, even
when fully charged, to keep the high
voltage battery temperature ready
for the next drive. This is important
when outside temperatures are
extremely hot or cold.
A vehicle cover, which can reduce
sun loading on the vehicle and
improve high voltage battery life, is
available from your dealer.
12-Volt Battery
The 12-volt battery is in the trunk,
under the center compartment
cover. Refer to the replacement
number shown on the original
battery label when a new 12-volt
battery is needed. The vehicle has
an Absorbed Glass Mat (AGM)
12-volt battery. Installation of a
standard 12-volt battery will result in
reduced 12-volt battery life.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts. Follow the charger
manufacturer's instructions.{Warning
WARNING:Battery posts,
terminals, and related
accessories contain lead and lead
compounds, chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm. Batteries also
contain other chemicals known to
the State of California to cause
cancer. WASH HANDS AFTER
HANDLING. SeeCalifornia
Proposition 65 Warning 0236.
Vehicle Storage
{Warning
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See Jump Starting -
North America 0299 for tips on
working around a battery without
getting hurt. Up to four weeks
.
Plug in the high voltage battery
charge cord if temperatures will
exceed 35 °C (95 °F) and keep
the 12-volt battery cables
connected.
Four weeks to 12 months
. Discharge the high voltage
battery until two or three bars
remain on the battery range
indicator (Battery symbol) on the
instrument cluster.
. Do not plug in the high voltage
battery charge cord.
. Remove the black negative (−)
cable from the 12-volt battery.
Attach a trickle charger to the
battery terminals or keep the
12-volt battery cables connected
and trickle charge from the
underhood remote positive (+)
and negative (−) terminals. See
Jump Starting - North America
0299 for the location of these
terminals.

Caution (Continued)
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
