Tire Pressure Monitor
This vehicle may have a Tire Pressure
Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in pressure
of one of the vehicle's tires. If the warning light comes on, stop as soon
as possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
See
Vehicle Load Limits 0188. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the tire
pressures are getting low and the tires
need to be inflated to the proper
pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.

SEATS AND RESTRAINTS 87
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly. The operation of the
airbag system can also be affected by
changing any parts of the front seats,
seat belts, airbag sensing and
diagnostic module, steering wheel,
instrument panel, inner door seals
including the speakers, any of the
airbag modules, ceiling or pillar
garnish trim, overhead console, front
sensors, side impact sensors, or airbag
wiring.
Your dealer and the service manual
have information about the location of
the airbag sensors, sensing and
diagnostic module, and airbag wiring.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced withnon-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). See
Passenger Sensing
System 082.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0311 for additional important
information.
If you have to modify your vehicle
because you have a disability and have
questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, call
Customer Assistance. See Customer
Assistance Offices 0359.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0126.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 078. See
your dealer for service.

Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0254.
If the light is f lashing : A

180 DRIVING AND OPERATING
1. Ease off the accelerator and then,if there is nothing in the way,
steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
. Acceleration Skid —too much
throttle causes the driving wheels
to spin. Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.
Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
. Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer
and vehicle control can be affected
when traction is reduced by water,
snow, ice, gravel, or other material
on the road. Learn to recognize
warning clues —such as enough
water, ice, or packed snow on
the road to make a mirrored
surface —and slow down when
you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
Track Events and
Competitive Driving
{Danger
High-performance features are
intended for use only on closed
tracks by experienced and qualified
drivers and should not be used on
public roads. High-speed driving,
aggressive cornering, hard braking,
and other high-performance driving
can be dangerous. Improper driver
inputs for the conditions may result
in loss of control of the vehicle,
which could injure or kill you or
others. Always drive safely.
Track events and competitive driving
may affect the vehicle warranty. See
the warranty manual before using the
vehicle for competitive driving.

DRIVING AND OPERATING 183
Run this procedure in a safe manner
and in compliance with all local and
state ordinances/laws regarding motor
vehicle operation. Run this procedure
only on dry pavement.
Racing/Track Brake Burnishing
Procedure
Caution
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. Apply the brakes 25 times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while
decelerating at 0.4 g. This is a
medium brake application. Drive
for at least 1 km (0.6 mi) between
applying the brakes. This first
step may be skipped if there are
more than 320 km (200 mi) on
the brake pads. 2. Repeatedly apply the brakes from
100 km/h (60 mph) to 25 km/h
(15 mph) while decelerating at
0.8 g. This is a hard brake
application, without activating
the Antilock Brake System (ABS).
Drive for at least 1 km (0.6 mi)
between stops. Repeat until the
brake pedal travel starts to
increase. Depending on
conditions, this should take no
longer than 25 brake
applications.
3. Cool down: Drive at 100 km/h (60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least
1 km (0.6 mi) between
applications.
Brake Cooling
On V-Series, remove front tire
deflectors if equipped, before track
driving for optimized brake cooling.
Wheel Alignment (V-Series Only)
Wheel alignment suggested specs for
track use:
. Front: -2.0 deg camber, 0.2 deg
total toe
. Rear: -1.7 deg camber, 0.2 deg
total toe
V-Series Vehicles Equipped with
the Original Equipment Tires
Follow the requirements and
recommendations for tire inflation
pressures while driving on various
types of tracks/courses. This helps to
achieve a well-balanced vehicle and
enhance tire traction performance.
Use good judgment to determine the
appropriate tire inflation pressure and
speeds for the track/course
configuration and environmental
conditions. Contact the tire
manufacturer if further assistance is
needed.
To maximize tire life, drive 805 km
(500 mi) prior to race track driving or
complete the minimum track running

11349156) - 2018 - CRC - 9/29/17
184 DRIVING AND OPERATING
that will increase the tire pressures by
35 kPa (5 psi). After this, immediately
let the tires cool to cold pressures.
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.
Driving and Operating
{Warning
Operating the vehicle at high speeds
can be dangerous. Improper tire
inflation pressure can put
additional 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
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).
Tire Inflation Pressure for Tracks
with Sustained High-Speed
Operation on Banked Turns
(e.g., Daytona International Speedway,
Indianapolis Motor Speedway,
or similar) Inflate tires to a minimum of 300 kPa
(44 psi) when cold.
Do not reduce tire inflation pressure
when hot.
Tire Inflation Pressure for Tracks
with Combined High-Speed and
High-Load Corners
(e.g., Nurburgring Nordschliefe, Spa
Francorchamps, or similar)
Inflate tires to a minimum of 260 kPa
(38 psi) when cold.
Limit vehicle speed to below 230 km/h
(143 mph) until 290 kPa (42 psi) is
reached.
For continuous track use, hot tire
inflation pressure may be adjusted to
a minimum of 290 kPa (42 psi).
Tire Inflation Pressure for Road/
Street Courses
(e.g., Virginia International Raceway,
Road Atlanta, or similar)
Inflate tires to a minimum of 240 kPa
(35 psi) cold.
