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.

Brake Burnishing
New brake pads must be
burnished before racing or
other competitive driving.
Caution
These procedures are
specific to the V-Series with
performance brake linings
package. This procedure
should not be run on other
models as damage may
result.
Caution
The new vehicle break-in
period should be completed
before performing the brake
burnishing procedure or
damage may occur to the
powertrain/engine. See New
Vehicle Break-In0265.
Caution
Brake pedal fade will occur
during any track burnish
procedure and can cause
brake pedal travel and force
to increase. This could
extend stopping distance
until the brakes are fully
burnished.
When performed as
instructed, these procedures
will not damage the brakes.
During the burnishing
procedure, the brake pads will
smoke and produce an odor.
The braking force and pedal
travel may increase. After the
procedure is complete, the
brake pads may appear white
at the rotor contact.
Perform these procedures in a
safe manner and in compliance
with all local and state
ordinances/laws regarding
motor vehicle operation.
Perform the procedures only
on dry pavement. As with all high performance
brake systems, some amount
of brake squeal is normal.
Street High Performance
Brake Burnishing Procedure
This section is for the V-Series
Blackwing with J57 carbon
ceramic brake rotors only.
This procedure should only be
run on a track or other
non-public area, and only on
dry pavement.
Caution
Brake fade will occur during
this track burnish procedure
and can cause brake pedal
travel and force to increase.
This could extend stopping
distance until the brakes are
fully burnished.
1. From a stop, accelerate as rapidly as possible without
activating traction control
to a speed of 100 km/h
(60 mph).

2. Using the G-Force Gaugein the HUD display, use
enough pedal force to
completely stop the vehicle
in four to five seconds.
(~0.7g Decel level to stop
the vehicle in a straight
line). If ABS activates,
braking is too hard.
3. Repeat the first two steps 20 consecutive times, this
should take about
five minutes.
4. After completing the 20 stops, cool the brakes by
driving for 8 km (5 mi) at
100 km/h (60 mph).
Alternative Closed Course
Brake Burnishing Procedure
This brake burnish procedure
should only be run on vehicles
with a factory equipped brake
system.
This procedure should only be
run on a track and only on dry
pavement. Brake pedal fade
will occur during this track
burnish procedure and can cause brake pedal travel and
force to increase. This could
extend stopping distance until
the brakes are fully burnished.
1. Start track lapping at lower speeds and lower
braking efforts for
three minutes of driving.
Allow for increased braking
distances due to reduced
brake output.
2. After Step 1, increase speed and braking effort
for the next six minutes of
lapping, gradually ending
up at 90% effort. Continue
to allow for increased
braking distance due to
reduced brake output.
3. Cool the brakes by lapping with minimal light braking
for six minutes.

Tire Inflation Pressure
Guidelines
Tire inflation pressures affect
vehicle handling and tire life,
and should be adjusted for
various types of tracks/
courses.
Inspect the tires prior to every
track/course session. Track/
course driving will reduce the
tire tread life.
To maximize tire life, drive
800 km (500 mi) prior to
racetrack driving or complete
the minimum track running
that will increase the tire
pressures by 35 kPa (5 psi).
After this, immediately let the
tires cool to cold pressures.

not use Line Lock in an area
that is accessible to the
public or where people or
property are located near
the vehicle.
Caution
Attempting to shift when
the drive wheels are
spinning and do not have
traction may cause damage
to the transmission. Damage
caused by misuse of the
vehicle is not covered by the
vehicle warranty. Do not
attempt to shift when the
drive wheels do not have
traction. Line Lock allows for locking
the front brakes
independently of the rear
brakes. This allows the rear
tires to spin when the throttle
is applied.

Driving on Wet Roads
Rain and wet roads can
reduce vehicle traction and
affect your ability to stop and
accelerate. Always drive
slower in these types of
driving conditions and avoid
driving through large puddles
and deep-standing or flowing
water.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -

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.

.Check all fluid levels and
brakes, tires, cooling system,
and transmission.
.Shift to a lower gear when
going down steep or long
hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill
slope can cause brake
overheating, can reduce
brake performance, and
could result in a loss of
braking. Shift the
transmission to a lower gear
to let the engine assist the
brakes on a steep downhill
slope.
{Warning
Coasting downhill in
N (Neutral) or with the
ignition off is dangerous.
This can cause overheating
of the brakes and loss of(Continued)
Warning (Continued)
steering assist. Always have
the engine running and the
vehicle in gear.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the
wheels and brake
components, always clear (Continued)
Caution (Continued)
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when
freezing rain begins to fall.
Avoid driving on wet ice or in
freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently.
Accelerating too quickly
causes the wheels to spin
and makes the surface under
the tires slick.
.Turn on Traction Control.

steering column lock may not
release with the wheels
turned off center. If this
happens, the vehicle may not
start. Move the steering wheel
from left to right while
attempting to start the
vehicle. If this does not work,
the vehicle needs service.
Do not turn the engine off
when the vehicle is moving.
This will cause a loss of power
assist in the brake and
steering systems and disable
the airbags.
If the vehicle must be shut off
in an emergency:1. Brake using a firm and steady pressure. Do not
pump the brakes
repeatedly. This may deplete power assist,
requiring increased brake
pedal force.
2. Shift the vehicle to N (Neutral). This can be
done while the vehicle is
moving. After shifting to
N (Neutral), firmly apply the
brakes and steer the
vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an
automatic transmission,
or Neutral with a manual
transmission. Turn the
ignition off.
