Brake Leak Detection
The hydraulic braking system
has advanced diagnostic
capability to help detect
hydraulic leaks, trapped air,
and other performance issues.
These diagnostics are active
when the hydraulic system is
powered. In order to avoid
inadvertently setting a leak
Diagnostic Trouble Code
(DTC), disconnect the battery
before servicing the brake
system.
If the vehicle sets a DTC
related to a brake system leak,
the Brake System Warning
Light will come on and vehicle
speed may be limited to 100
kph (62 mph). Any time a leak
DTC is set, the vehicle should
be inspected carefully for
evidence of a leak and should
be repaired immediately. See
your dealer.Brake Fade Warning Assist
The Brake Fade Warning
Assist system monitors the
performance of the brake
system. If the system detects
brake fade, or if the brake fluid
is near the boiling point, the
driver will be alerted.
The Brake Fade Warning
Assist system is designed for
use with the factory-installed
brake pads or GM approved
replacement pads. If the brake
pads on the vehicle need to be
replaced, use GM approved
brake pads. If this is not done,
the brake fade warning
system may not function
properly.
Stage 1 :
The DIC displays a
“Reduce Braking to Avoid
Overheating” message, a
chime sounds and brake pedal
effort and travel is increased.
When the message displays,
the driver should back up
braking points and reduce
brake usage in order to reduce brake temperature. This will
allow for continued lapping
with no speed limitations.
Stage 2 :
The DIC displays a
Brakes Overheated Service
Now message, a chime
sounds, and brake pedal effort
and travel is further increased.
This code indicates that the
brake fluid temperature is
excessive and is about to boil.
The system limits vehicle
speed to 100 km/h (62 mph).
The driver should immediately
start a cool down lap if on the
track. If this message displays,
the vehicle needs to be
serviced. The brake system
needs to cool down, and the
brake fluid must be
immediately flushed with DOT
4 for street use, or to a
qualified DOT 4 race fluid for
track use. Boiled brake fluid is
compromised and must be
replaced.

258 Driving and Operating
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
Caution
Driving through deep
puddles or standing water
can cause water to come in
through the engine air intake
and damage the engine.
If deep puddles or standing
water cannot be avoided,
proceed with caution and do
not exceed 8 km/h (5 mph).
Do not drive through water
that may come close to or
cover the vehicle’s
underbody.
Hydroplaning
Hydroplaning is dangerous.
Water can build up under the
vehicle's tires so they actually
ride on the water. This can
happen if the road is wet
enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.There is no hard and fast rule
about hydroplaning. The best
advice is to slow down when
the road is wet.
Other Rainy Weather Tips
Besides slowing down, other
wet weather driving tips
include:
.Allow extra following
distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer
fluid reservoir filled.
.Have good tires with proper
tread depth. See Tires
0418.
.Turn off cruise control.
Hill and Mountain
Roads
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced
and in good shape.
