Brakes
Brake Fluid
The brake master cylinder
reservoir is lled with
DOT-3 brake uid. See
Engine Compartment
Overview on page 5-14for
the location of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down:
The brake uid level goes down because of normal
brake lining wear. When new linings are installed,
the uid level goes back up.
A uid leak in the brake hydraulic system can also
cause a low uid level. Have the brake hydraulic
system xed, since a leak means that sooner
or later the brakes will not work well.Do not top off the brake uid. Adding uid does not
correct a leak. If uid is added when the linings are worn,
there will be too much uid when new brake linings are
installed. Add or remove brake uid, as necessary, only
when work is done on the brake hydraulic system.
{CAUTION:
If too much brake uid 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 uid only when work is
done on the brake hydraulic system.
If the ignition is in ON/RUN and the brake uid is low,
the Service Brake System message displays in the DIC.
SeeDIC Warnings and Messages on page 3-58.
When the brake uid falls to a low level, the brake
warning light comes on. SeeBrake System Warning
Light on page 3-39.
5-42

What to Add
DOT-3 brake uid is recommended. DOT-4 brake uid is
also compatible with the vehicle’s brake system parts.
However, if DOT-4 uid is used, it is recommended that
the brake hydraulic system be ushed and relled with
new DOT-4 uid at a regular maintenance service every
two years. SeeAdditional Required Services on
page 6-6. Use new brake uid from a sealed container
only. SeeRecommended Fluids and Lubricants on
page 6-14.
Always clean the brake uid reservoir cap and the area
around the cap before removing it. This helps keep
dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake uid.Notice:
Using the wrong uid can badly damage brake
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 uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 5-110.

Recommended Fluids and
Lubricants
Fluids and lubricants identied below by name, part
number, or specication can be obtained from your
dealer/retailer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special engine
oil meeting GM Standard GM4718M.
Oils meeting this standard can be
identied as synthetic, and should
also be identied with the American
Petroleum Institute (API) Certied for
Gasoline Engines starburst symbol.
However, not all synthetic API oils
with the starburst symbol will meet
this GM standard. Look for and use
only an oil that meets GM Standard
GM4718M. For the proper viscosity,
seeEngine Oil on page 5-18.
Engine Coolant50/50 mixture of clean, drinkable
water and use only DEX-COOL
