To help the generator recharge the battery quickly,
you can reduce the load on the electrical system
by turning off the accessories.
The normal battery voltage range is
11.5 to 15.5 volts. You can monitor battery voltage
on the DIC by pressing the information button
until you nd BATTERY VOLTS.
CHANGE ENGINE OIL SOON
This message displays when service is required
for your vehicle. See your dealer. SeeEngine
Oil on page 380andScheduled Maintenance on
page 505for more information.
When you reset the CHANGE ENGINE OIL
SOON message by clearing it from the display,
you still must reset the engine oil life system
separately. For more information on resetting the
engine oil life system, seeEngine Oil Life
System on page 383.
CHECK BRAKE FLUID
This message displays if the ignition is on to
inform the driver that the brake uid level is low.
Have the brake system serviced by your dealer as
soon as possible. SeeBrake System Warning
Light on page 248for more information.
CHECK GAS CAP
This message displays when the fuel cap has not
been fully tightened. Recheck the fuel cap to
ensure that it is on and tightened properly.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the tire
pressure in one of the tires needs to be checked.
SeeDIC Controls and Displays on page 258
for more information on checking your vehicle’s
tire pressures. If a tire pressure message appears
on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on
the Tire Loading Information label. SeeTire
Pressure Monitor System on page 433and
Ination - Tire Pressure on page 431for more
information. If the tire pressure is low, the low tire
pressure warning light comes on. SeeLow Tire
Pressure Warning Light on page 249.

If your vehicle is equipped with front compartment
underhood sight shields, before closing the
hood be sure to reinstall the sight shields. To
reinstall the shields, locate the tabs on the left and
right sides and insert them into the openings in
the tower to tower brace. Then insert the fasteners
into the top of the shield and push the fasteners
back into place.

Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 373for
reservoir location
and access.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you
add uid when your linings are worn, then you will
have too much uid when you get new brake
linings. You should add or remove brake uid, as
necessary, only when work is done on the
brake hydraulic system.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn
if the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system.
If the ignition is on and the brake uid is low, the
CHECK BRAKE FLUID message will be
displayed in the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 264.
405

What to Add
When you do need brake uid, DOT-3 brake uid
is recommended for use. DOT-4 brake uid is
also compatible with your vehicle’s brake system
parts. However, if you choose to use DOT-4
uid, it is recommended that you ush your brake
hydraulic system and rell it with new DOT-4
uid at a regular maintenance service every
two years. SeeAdditional Required Services on
page 508. Use new brake uid from a sealed
container only. SeeRecommended Fluids
and Lubricants on page 516.
Always clean the brake uid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake uid.Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 480.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound may come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal rmly.

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. You
should look for and use only oil that
meets GM Standard GM4718M. GM
