Infotainment System 191
Global Positioning
System (GPS)
If equipped, the position of the
vehicle is determined by using
satellite signals, various
vehicle signals, and map data.
At times, other interference
such as the satellite condition,
road configuration, condition
of the vehicle, and/or other
circumstances can affect the
navigation system's ability to
determine the accurate
position of the vehicle.
The GPS shows the current
position of the vehicle using
signals sent by GPS satellites.
When the vehicle is not
receiving signals from the
satellites, a symbol appears in
the status bar.
This system might not be
available or interference can
occur if any of the following
are true:
.Signals are obstructed by
tall buildings, trees, large
trucks, or a tunnel.
.Satellites are being repaired
or improved.
For more information if the
GPS is not functioning
properly, see Problems with
Route Guidance 0192 and
If the System Needs Service
0 192.
Vehicle Positioning
At times, the position of the
vehicle on the map could be
inaccurate due to one or more
of the following reasons:
.The road system has
changed.
.The vehicle is driving on
slippery road surfaces such
as sand, gravel, or snow.
.The vehicle is traveling on
winding roads or long,
straight roads.
.The vehicle is approaching a
tall building or a large
vehicle.
.The surface streets run
parallel to a freeway.
.The vehicle has been
transferred by a vehicle
carrier or a ferry.
.The current position
calibration is set incorrectly.
.The vehicle is traveling at
high speed.
.The vehicle changes
directions more than once,
or the vehicle is turning on a
turn table in a parking lot.
.The vehicle is entering
and/or exiting a parking lot,
garage, or a lot with a roof.
.The GPS signal is not
received.
.A roof carrier is installed on
the vehicle.
.Tire chains are installed on
the vehicle.
.The tires are replaced
or worn.
.The tire pressure for the
tires is incorrect.
.This is the first navigation
use after the map data is
updated.

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.

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.

much weight it may
properly carry: the Tire and
Loading Information label
and the Certification label.
{Warning
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either
the maximum front or
rear Gross Axle Weight
Rating (GAWR). This can
cause systems to break
and change the way the
vehicle handles. This
could cause loss of
control and a crash.
Overloading can also
reduce stopping
performance, damage the
tires, and shorten the life
of the vehicle. Tire and Loading
Information Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's
center pillar (B-pillar). The
Tire and Loading
Information label shows the
number of occupant
seating positions (1), and
the maximum vehicle
capacity weight (2) in
kilograms and pounds. The Tire and Loading
Information label also
shows the tire size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information on
tires and inflation see Tires
0
418 and
Tire Pressure 0427.
There is also important
loading information on the
Certification label. It may
show the Gross Vehicle
Weight Rating (GVWR) and
the Gross Axle Weight
Rating (GAWR) for the
front and rear axle. See
“Certification Label” later in
this section.

Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual
for information regarding
the tire warranty and
where to get service. For
additional information refer
to the tire manufacturer.
{Warning
.Poorly maintained and
improperly used tires
are dangerous.
.Overloading the tires
can cause overheating
as a result of too much
(Continued)
Warning (Continued) flexing. There could be
a blowout and a serious
crash. See Vehicle Load
Limits 0261.
.Underinflated tires
pose the same danger
as overloaded tires. The
resulting crash could
cause serious injury.
Check all tires
frequently to maintain
the recommended
pressure. Tire pressure
should be checked
when the tires are cold.
.Overinflated tires are
more likely to be cut,
punctured, or broken by
a sudden impact —such
as when hitting a
pothole. Keep tires at
the recommended
pressure.

Warning (Continued)
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.
.Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc.
.Improperly repaired
tires can cause a crash.
Only your dealer or an
authorized tire service
center should repair,
replace, dismount, and
mount the tires.
.Do not spin the tires in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,

All-Season Tires
This vehicle may come with
all-season tires. These tires
are designed to provide good
overall performance on most
road surfaces and weather
conditions. Original equipment
tires designed to GM's specific
tire performance criteria have
a TPC specification code
molded onto the sidewall.
Original equipment all-season
tires can be identified by the
last two characters of this
TPC code, which will be “MS.”
Consider installing winter tires
on the vehicle if frequent
driving on snow or ice-covered
roads is expected. All-season
tires provide adequate
performance for most winter
driving conditions, but they
may not offer the same level of traction or performance as
winter tires on snow or
ice-covered roads. See Winter
Tires
0419.
Winter Tires
This vehicle was not originally
equipped with winter tires.
Winter tires are designed for
increased traction on snow
and ice-covered roads.
Consider installing winter tires
on the vehicle if frequent
driving on ice or snow covered
roads is expected. See your
dealer for details regarding
winter tire availability and
proper tire selection. Also, see
Buying New Tires 0437.
With winter tires, there may
be decreased dry road
traction, increased road noise,
and shorter tread life. After
changing to winter tires, be
alert for changes in vehicle
handling and braking.
