Warning (Continued)
cause the wheels to become
loose or come off, resulting
in a crash. See Capacities
and Specifications0482 for
wheel nut torque
specifications.
Caution
If the vehicle is used for
track events and
competitive driving, the
engine may use more oil
than it would with normal
use. Low oil levels can
damage the engine. Check
the oil level often and
maintain the proper level.
See Engine Oil 0383.
Competitive Driving Mode can
be selected. See Driver Mode
Control 0293.
Seat Belts
Lap-Shoulder Belt
If equipped, the driver seat
belt has an Automatic Locking
Retractor (ALR). This feature
is useful in performance
driving scenarios where the
driver wants to be held in the
seat more tightly to take
advantage of the aggressive
bolstering of the seat.
1. Move the seat 8-10 cm (3-4 in) rearward from the
normal driving position.
2. Pull the driver shoulder belt out as far as it will go,
until it stops, to set the
lock. While holding the
shoulder belt in this
position, buckle the belt.
When the shoulder belt is
released, the retractor will
make a ratchet sound
when it retracts. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor. 3. Adjust the belt, and then
move the seat forward
8-10 cm (3-4 in) to the
desired driving position.
This will secure the belt.
The belt fit should be tight,
but not uncomfortable.
To unlatch the belt, press
the button on the buckle.
The belt should return to
its stowed position.
Axle Fluid
Axles must have 2 400 km
(1,500 mi) before being used in
track driving.
The front, if equipped with
AWD, and rear axle fluid
temperatures may be higher
than when driving in severe
conditions. Drain and refill with
new fluid after the first racing
or competitive driving event,
and then after every 24 hours
of racing or competitive
driving. See your dealer for
the correct fluid.

254 Driving and Operating
Tire Inflation Pressure High
Speed
See Tire Pressure for
High-Speed Operation0429.
Tire Inflation Pressure for
Track Driving
For driving on a race course,
if the vehicle is equipped with
275/35ZR19 (100Y) and
305/30ZR19 (102Y) tires, set
the cold (stationary) tire
pressures to 28 psi. During
track sessions, set the tire
pressures at 35 to 38 psi for
hot tires. If pressures exceed
38 psi, adjust the pressures
down to 35 to 38 psi. Return
the tires to the recommended
cold tire inflation pressure
when track driving has ended.
Driving and Operating
{Warning
Operating the vehicle at high
speeds can be dangerous.
Improper tire inflation
pressure can put additional (Continued)
Warning (Continued)
strain on the tires and can
cause a sudden failure. Make
sure the tires are in
excellent condition, and use
the correct cold tire inflation
pressure for the vehicle load
and track/course.
{Warning
Tracks/courses put high
loads on tires operating at
high speed, which can lead
to tire failure if not inflated
properly. Always limit vehicle
cargo to the driver plus one
passenger with no additional
cargo.
{Warning
Track/course loads wear
tires both on the tread and
internal to the tire. When
driven in track/course(Continued)
Warning (Continued)
conditions, even if tread is
not worn down to the
treadwear indicator, tires
must be replaced after the
equivalent of two tanks of
fuel or approximately 160 km
(100 mi).
Custom Launch Control (If
Equipped)
Custom Launch Control allows
the following parameters for
Launch Control to be modified:
.Launch RPM
.Slip Target (5%–15%)
.Surface Type
To adjust the Launch RPM, all
of these conditions must
be met:
.The vehicle must be in Track
Mode. See “Track Mode”
under Driver Mode Control
0 293.

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

266 Driving and Operating
Caution (Continued)
.Check engine oil with
every refueling and add if
necessary. Oil and fuel
consumption may be
higher than normal during
the first
2 414 km (1,500 mi).
.To break in new tires,
drive at moderate speeds
and avoid hard cornering
for the first
322 km (200 mi). New tires
do not have maximum
traction and may tend
to slip.
.New brake linings also
need a break-in period.
Avoid making hard stops
during the first
322 km (200 mi). This is
recommended every time
brake linings are replaced.
.Should the vehicle be used
for racing or competitive
driving (after break-in), the
rear axle lubricant must be
replaced beforehand.See Track Events and
Competitive Driving (V-Series
and V-Series Blackwing)
0246.
On new vehicles, the various
mechanical and electrical
systems experience a
“break-in” period during the
first 6,400 km (4,000 miles) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle’s battery to achieve
the best operation of the
vehicle, including fuel
economy.
Composite Materials
This vehicle may be equipped
with parts containing carbon
fiber, sheet-molding
compound, or other composite
materials. Dealer-installed
accessories may also contain
composite materials.
{Warning
Exposed edges of parts
containing carbon fiber and
other composite materials
can be sharp. Contact with
these parts could result in
injury. Use caution to avoid
contacting these parts,
including when washing the
vehicle. If the parts are
damaged, replace the parts
promptly with replacements
from your dealer.

268 Driving and Operating
The vehicle may have an
electric steering column lock.
The lock is activated when the
vehicle is switched to OFF and
the driver door is opened.
A sound may be heard as the
lock actuates or releases. The
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.
4. Set the parking brake. See Electric Parking Brake
0288.
{Warning
Turning off the vehicle while
moving may cause loss of
power assist in the brake
and steering systems and
disable the airbags. While
driving, only shut the vehicle
off in an emergency. If the vehicle cannot be pulled
over, and must be shut off
while driving, press and hold
ENGINE START/STOP for
longer than two seconds,
or press twice within
five seconds.
Accessory Mode (Amber
Indicator Light) :
This mode
allows the use of some
electrical accessories when
the engine is off.
With the ignition off, pressing
the button once without the
brake pedal applied will place
the ignition system in
accessory mode.
The ignition will switch from
accessory mode to OFF after
five minutes to prevent
battery rundown.
ON/RUN/START (Green
Indicator Light) : This mode is
for driving and starting. With
the ignition off, and the brake
pedal applied, pressing the
button once will place the
ignition system in ON/RUN/
START. Once engine cranking
