The road tire is larger than the spare, so
you must adjust the tray to its lower
position. Lift and push the tire carrier
tray toward the front of the vehicle. The
tray will drop to its lower position. Put
the flat road tire
on the tray. Lift the
latch bolt, push it toward the front
of the
vehicle, and the bolt will drop down to
the lower position. Put the
hooked end of the wheel wrench
into the slot in the tray. Lift the tray using
the wheel wrench and insert the latch bolt
into the notch
in the tray. To raise the tray,
use the socket end of the wheel wrench to
turn the latch bolt clockwise. Turn the
latch bolt until it is snug.
Put the wheel wrench back in its place
under the driver's seat. Be sure to tighten
the wingnuts.

Fuels in Foreign Countries
If you plan on driving in another country
outside the
U.S. or Canada, unleaded
fuel may be hard to find.
Do not use
leaded gasoline. If you use even one
tankful, your emission controls won’t
work well or at all. With continuous use,
spark plugs can get fouled, the exhaust
system can corrode, and your engine oil
can deteriorate quickly. Your vehicle’s
oxygen sensor will be damaged. All of
that means costly repairs that wouldn’t
be covered by your warranty.
To check on fuel availability, ask an auto
club, or contact a major oil company that
does business
in the country where you’ll
be driving.
You can also write us at the following
address for advice. Just tell
us where
you’re going and give your Vehicle
Identification Number (VIN).

Filling
Your Tank
The cap is under a hinged door on the rear
of your vehicle. While
refueling, place the cap in the

To take
off the cap, turn it slowly to the
left (counterclockwise).

Downloaded from www.Manualslib.com manuals search engine Substitute Oil (LT1 Only): When adding
oil to maintain engine oil level, if an oil
meeting GM Standard GM4718M is not
available, you can use oil designated
either
SAE 5W-30 API Service SH or SG
at all temperatures, or
SAE 1OW-30 API
Service
SH or SG at temperatures above
0°F (-18°C). This oil should not be used
for an oil change.
Substitute Oil (LT5 Only): When adding
oil to maintain engine oil level, if an oil
meeting
GM Standard GM4718M is not
available, you can use oil designated SAE
1OW-30 API Service SH or
SG at all
temperatures. This oil should not be used
for an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your
Chevrolet dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles
It’s below freezing outside and most
trips are less than
10 miles (16 km).
(6 km).
The engine is at low speed most of
the time (as
in stop-and-go traffic).
Most trips are through dusty places.
If any one of these is true for your
vehicle, you need to change your oil and
filter every 3,000 miles
(5 000 km) or
3 months
- whichever comes first.
(See “Engine Oil Life Monitor” in the
Index.)
If none of them is true, change the oil
every 7,500 miles
( 12 500 km) or 12
months
- whichever comes first. Change
the filter at the first oil change and at
every other oil change after that. (See
“Engine Oil Life Monitor” in the Index.)
Engine Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0 “F (- 18 “C) or colder. If
your vehicle has this feature, see “Engine
Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains certain elements that may be
unhealthy for your skin and could even
cause cancer? Don’t let used oil stay on your
skin for very long. Clean your skin
and nails with soap and water, or a good
hand cleaner. Wash or throw away
clothing or rags containing used engine
oil. (See the manufacturer’s warnings
about the use and disposal of oil
products.)
Used oil can be a real threat to the
environment. If you change your own oil,
be sure to drain all free-flowing oil from
the filter before disposal. Don’t ever
dispose of oil by putting it in the trash,
pouring it on the ground, into sewers, or
into streams or bodies of water. Instead,
recycle
it by taking it to a place that
collects used oil. If you have a problem
properly disposing of your used oil, ask
your dealer, a service station or
a local
recycling center for help. L 1

Downloaded from www.Manualslib.com manuals search engine Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the brake
fluid level in your master cylinder might
go down. The first is that the brake fluid
goes down to an acceptable level during
normal brake lining wear. When new
linings are put in, the fluid level goes
back up. The other reason is that fluid is
leaking out of the brake system.
If it is,
you should have your brake system fixed,
since a leak means that sooner or later
your brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t
correct a leak. If you add fluid when your
linings are worn, then you’ll have too
much fluid when you get new brake
linings. You should add (or remove)
brake fluid, as necessary, only when work
is done on the brake hydraulic system. When your brake fluid falls to a
low level, your brake warning light,
“SERVICE ABS” light and “SERVICE
ASR” light will come on. Also, the
anti-lock brake and Acceleration Slip
Regulation systems are disabled. See
“Brake System Warning Light” in the
Index.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco-
Supreme
1 l@ (GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the brak
fluid reservoir cap before removing it.
