Driving and Operating 9-31
Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch for the
EPB is in the center console. The
EPB can always be activated,
even if the ignition is off. To avoid
draining the battery, do not cycle the
EPB too often without the engine
running. The EPB can be left
applied while the vehicle is parked.
The system has a parking brake
status light and a parking brake
warning light. SeeBrake System
Warning Light on page 5‑16. There are also Driver Information Center
(DIC) messages. See
Brake System
Messages on page 5‑25 for more
information. In case of insufficient
electrical power, the EPB cannot be
applied or released.
Before leaving the vehicle, check
the parking brake status light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied any time
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the EPB switch. Once fully applied,
the parking brake status light will be
on. While the brake is being applied,
the status light will flash until full
apply is reached. If the light does
not come on, or remains flashing,
you need to have the vehicle
serviced. Do not drive the vehicle if
the parking brake status light is
flashing. See your dealer. See
Brake System Warning Light on
page 5‑16 for more information. If the EPB is applied while the
vehicle is in motion, a chime will
sound, and a DIC message will be
displayed. See
Brake System
Messages on page 5‑25. The
vehicle will decelerate as long as
the switch is held in the up position.
Releasing the EPB switch during
the deceleration will release the
parking brake. If the switch is held
in the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the parking brake status light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
A DIC message will be displayed.
See Brake System Messages on
page 5‑25. If this light flashes
continuously, release the EPB, and
attempt to apply it again. If this light
continues to flash, do not drive the
vehicle. See your dealer.
If the parking brake warning light
is on, the EPB has detected an
error in another system and is
operating with reduced functionality.

10-18 Vehicle Care
Brake Fluid
The brake master cylinder and, on
manual transmission vehicles, the
clutch hydraulic system use the
same reservoir. SeeEngine
Compartment Overview on
page 10‑6 for the location of the
reservoir. The reservoir is filled
with with either DOT 3 or DOT 4
brake fluid as indicated on the
reservoir cap.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
.The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake/clutch
hydraulic system can also cause
a low fluid level. Have the brake/
clutch hydraulic system fixed,
since a leak means that sooner
or later the brakes will not
work well.
Do not top off the brake/clutch 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/clutch 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/clutch
hydraulic system.
Checking Brake Fluid
The brake/clutch fluid can be
checked without taking off the cap
by looking at the brake/clutch fluid
reservoir.
The fluid level should be above
MIN. If it is not, have the brake/
clutch hydraulic system checked to
see if there is a leak.
After work is done on the brake/
clutch hydraulic system, make sure
the level is above MIN but not over
the MAX mark.
When the brake/clutch fluid falls to a
low level, the brake warning light
comes on. See Brake System
Warning Light on page 5‑16.
What to Add
If the vehicle has DOT 3 brake fluid,
as indicated on the reservoir cap,
use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11‑12.

Vehicle Care 10-65
Notice:Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
vehicle.
The jump start positive post (B) is
located in the engine compartment
on the driver side of the vehicle. The jump start negative grounding
point (D) is the engine block or an
engine mounting bolt. Connect
to a spot as far away from the
discharged battery as possible.
These locations are used instead of
a direct connection to the battery.
The positive jump start connection
is under a trim cover. Open the
cover door to expose the terminal.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the shift lever in P (Park).
See Shifting Into Park on
page 9‑23. Notice:
If any accessories are
left on or plugged in during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
vehicle warranty. Whenever
possible, turn off or unplug all
accessories on either vehicle
when jump starting the vehicle.
4. Turn the ignition to LOCK/OFF.
Turn off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.

Service and Maintenance 11-9
Battery
The battery supplies power to
start the engine and operate any
additional electrical accessories.
.To avoid break‐down or failure to
start the vehicle, maintain a
battery with full cranking power.
.Trained dealer technicians have
the diagnostic equipment to test
the battery and ensure that the
connections and cables are
corrosion‐free.
Belts
.Belts may need replacing if
they squeak or show signs of
cracking or splitting.
.Trained dealer technicians
can inspect the belts and
recommend replacement when
necessary. Brakes
Brakes stop the vehicle and are
crucial to safe driving.
.Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping.
.Trained dealer technicians have
access to tools and equipment
to inspect the brakes and
recommend quality parts
engineered for the vehicle.
Fluids
Proper fluid levels and approved
fluids protect the vehicle’s
systems and components. See
Recommended Fluids and
Lubricants on page 11‑12 for GM
approved fluids.
.Engine oil and windshield
washer fluid levels should be
checked at every fuel fill.
.Instrument cluster lights may
come on to indicate that fluids
may be low and need to be
filled. Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi‐point inspection, your
dealer can inspect the hoses and
advise if replacement is needed.
Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
.With a multi‐point inspection,
your dealer can check the lamps
and note any concerns.
