When to Check and What
to Use
The brake/hydraulic clutch fluid
reservoir cap has this symbol on it.
The common hydraulic clutch and
brake master cylinder fluid reservoir
is filled with either DOT 3 or DOT 4
brake fluid as indicated on the
reservoir cap. SeeEngine
Compartment Overview on
page 10‑6 for reservoir location.
How to Check and Add Fluid
Visually check the brake/clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The brake/
hydraulic clutch fluid system should
be closed and sealed. Do not remove the cap to check the
fluid level or to top‐off the fluid level.
Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
Engine Air Cleaner/Filter
See
Engine Compartment Overview
on page 10‑6 for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
scheduled maintenance intervals
and replace it at the first oil change
after each 80 000 km (50,000 mile)
interval. See Scheduled
Maintenance on page 11‑2 for more
information. If you are driving in
dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release loose dust and dirt. If the filter
remains covered with dirt, a new
filter is required.
To inspect or replace the engine air
cleaner/filter:
2.0 L L4 Engine
1. Open the hood. See
Hood on
page 10‑5.
A. Electrical Connector
B. Air Duct Clamp
C. Screws (5)
2. Disconnect the outlet duct by loosening the air duct clamp (B).

Vehicle Care 10-27
If the vehicle has DOT 4 brake fluid,
as indicated on the reservoir cap,
use only new DOT 4 brake fluid
from a sealed container. It is
recommended that the brake/clutch
hydraulic system be flushed and
refilled with new DOT 4 fluid at a
regular maintenance service every
two years. SeeScheduled
Maintenance on page 11‑2 and
Recommended Fluids and
Lubricants on page 11‑6.
Always clean the brake/clutch fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{WARNING
With the wrong kind of fluid in the
brake/clutch hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake/clutch fluid. Notice
.Using the wrong fluid can
badly damage brake/clutch
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid.
.If brake fluid is spilled on
the vehicle's painted
surfaces, the paint finish can
be damaged. Be careful not
to spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
Refer to the replacement number
shown on the original battery label
when a new battery is needed. See
Engine Compartment Overview on
page 10‑6 for battery location.
{DANGER
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
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 on
page 10‑70 for tips on working
around a battery without
getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.

10-30 Vehicle Care
Wiper Blade Replacement
Windshield wiper blades should be
inspected for wear or cracking. See
Scheduled Maintenance on
page 11‑2for more information.
It is a good idea to clean or replace
the wiper blade assembly on a
regular basis or when worn. For
proper windshield wiper blade
length and type, see Maintenance
Replacement Parts on page 11‑8.
Notice: Allowing the wiper blade
arm to touch the windshield when
no wiper blade is installed could
damage the windshield. Any
damage that occurs would not be
covered by your warranty. Do not
allow the wiper blade arm to
touch the windshield.
To replace the wiper blade:
1. Pull the wiper assembly away from the windshield.
2. Lift up on the latch in the middleof the wiper blade where the
wiper arm attaches.
3. With the latch open, pull the wiper blade down toward the
windshield far enough to release
it from the J-hooked end of the
wiper arm.
4. Remove the wiper blade.
5. Reverse Steps 1 through 3 for wiper blade replacement.
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to a dealer for
service.

12. Turn the ignition to LOCK/OFF.
13. Set all four tires to therecommended air pressure
level as indicated on the Tire
and Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord
or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). See
Scheduled Maintenance on
page 11‑2.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Any time unusual wear is
noticed, rotate the tires as soon
as possible and check the wheel
alignment. Also check for
damaged tires or wheels. Also
check for damaged tires or
wheels. See When It Is Time for New Tires on page 10‑61
and
Wheel Replacement on
page 10‑61.
Use this rotation pattern when
rotating the tires.
Do not include the compact
spare tire in the tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated See

Reporting Safety
Defects
Reporting Safety Defects
to the United States
Government
If you believe that your vehicle
has a defect which could cause
a crash or could cause injury or
death, you should immediately
inform the National Highway
Traffic Safety Administration
(NHTSA) in addition to notifying
General Motors.
If NHTSA receives similar
complaints, it may open an
investigation, and if it finds that
a safety defect exists in a group
of vehicles, it may order a recall
and remedy campaign.
However, NHTSA cannot
become involved in individual
problems between you, your
dealer, or General Motors.
