150 Driving and Operating
1. Ease off the accelerator andthen, 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
(Z51 Only)
Vehicles without Z51 package
should not be used for 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

160 Driving and Operating
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a low
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
may need to be towed out. If the
vehicle does need to be towed out,
seeTowing the Vehicle 0271.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how 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 distance,
damage the tires, and shorten
the life of the vehicle.

clutch. After the vehicle is launched,
the system continues in Competitive
Driving Mode or PTM.
Competitive Driving Mode, PTM,
and Launch Control are systems
designed for a closed course race
track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.
Caution
The new vehicle break-in period
should be completed before using
the launch control feature,
otherwise performance will be
limited and damage may occur to
the powertrain/engine. SeeNew
Vehicle Break-In 0163.
Limited-Slip Differential
(without Z51)
The mechanical limited-slip
differential can give more traction on
snow, mud, ice, sand, or gravel.
It works like a standard axle most of the time, but when traction is low,
this feature allows the drive wheel
with the most traction to move the
vehicle. See
Competitive Driving
Mode 0192 and
Maintenance Schedule 0286.
Limited-Slip Differential
(with Z51)
The Electronic Limited-Slip
Differential (eLSD) is a hydraulically
actuated clutch system inside the
transaxle. It can infinitely vary the
clutch engagement between 0 and
2250 N*m (1659 lb-ft) of breakaway
torque between the rear wheels.
When necessary it responds from
open to full engagement in fractions
of a second. Smaller clutch
adjustments happen even faster.
The eLSD:
.
Uses the vehicle sensors and
driver inputs to determine the
optimum amount of clutch
engagement for the conditions. .
Improves traction while
cornering by changing the
engagement to achieve a
balance between directional
control and acceleration.
. Provides optimal engagement
for high-speed control and
stability without affecting precise
steering and turn-in.
. Improves vehicle stability during
spirited driving and evasive
maneuvers. It is fully integrated
with the Active Handling and
Performance Traction
Management (PTM) systems (if
equipped).
There are unique calibrations based
on the Traction Control System
(TCS) setting. eLSD modes change
automatically when the traction
control button is pressed. No unique
input from the driver is required.
. Mode 1 is the standard mode
when the vehicle is started.
It provides a touring calibration
with an emphasis on vehicle
stability. Mode 1 is also used in
PTM Wet mode.

196 Driving and Operating
.Mode 2 is engaged when both
TCS and StabiliTrak are turned
off. This calibration provides
more nimble corner turn-in, and
is biased for better traction out of
corners.
. Mode 3 is engaged when PTM is
engaged in Dry, Sport 1 & 2, and
Race modes. This is a nimble
calibration with similar
functionality as eLSD Mode 2,
however, it is integrated to work
with PTM.
. Mode 4 is engaged when TCS is
selected off, but StabiliTrak
remains on. Vehicle stability is
still the priority, while allowing for
optimized traction out of corners.Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the Traction Control System (TCS)
begins to limit wheel spin while you
are using cruise control, the cruise
control automatically disengages.
See Traction Control/Electronic
Stability Control 0182. When road conditions allow for using safely
again, cruise control can be turned
back on.
If the brakes are applied, cruise
control disengages.
Cruise control will disengage if
either TCS or StabiliTrak/Electronic
Stability Control (ESC) is turned off.

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, seeBuying New Tires 0261.
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.
If using winter tires:
. Use tires of the same brand and
tread type on all four wheel
positions.
. Use only radial ply tires of the
same size, load range, and
speed rating as the original
equipment tires. Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Run-Flat Tires
This vehicle, when new, had run-flat
tires. There is no spare tire, no tire
changing equipment, and no place
to store a tire in the vehicle.
The vehicle also has a Tire
Pressure Monitor System (TPMS)
that indicates a loss of tire pressure
in any of the tires.
{Warning
If the low tire warning light
displays on the instrument cluster,
the handling capabilities will be
reduced during severe
maneuvers. Driving too fast could
cause loss of control and you or
others could be injured. Do not
(Continued)
Warning (Continued)
drive over 80 km/h (50 mph) when
the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.
Run-flat tires can be driven on with
no air pressure. There is no need to
stop on the side of the road to
change the tire. Continue driving;
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. To prevent permanent
damage, the tire can be driven with
no air pressure for up to 80 km
(50 mi) at speeds slower than
80 km/h (50 mph) when carrying a
load of driver plus one passenger.
When carrying a heavier load, total
distance driven without air should
be reduced. As soon as possible,
contact the nearest authorized GM
or run-flat servicing facility for
inspection and repair or
replacement.
