To turn off the DRL, turn the exterior
lamp control to
O. The DRL will stay
off until the control is toggled again.
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps and parking
lamps come on automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps
will come on when they are not
needed. The system may also turn on the
headlamps and parking lamps when
driving through a parking garage or
tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
DRL. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control
0129.
When it is bright enough outside,
the headlamps and parking lamps
will turn off or may change to
Daytime Running Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off. To turn automatic headlamp system
back on, turn the band to
Oagain,
then release it.
If the automatic headlamp system
has the headlamps turned on and
you turn the ignition off, the
headlamps will turn off. When the
driver door is opened the
headlamps and parking lamps will
illuminate for a period of time.
The length of the delayed
illumination period can be changed.
See “Exit Lighting” underVehicle
Personalization 0116.
The regular headlamp system
should be turned on when needed.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on and the exterior lamp control is in
AUTO, the headlamps, parking
lamps, and other exterior lamps will
come on. The time it takes for the
lamps to turn on depends on the
wiper speed. When the wipers are
turned off, the lamps turn off. To
disable, move the exterior lamp
control to
Oor;.

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.

SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground. This
zone starts at approximately the
middle of the vehicle and goes back
5 m (16 ft).
How the System Works
The SBZA symbol lights up in the
side mirrors when the system
detects a moving vehicle in the next
lane over that is in the side blind
zone. This indicates it may beunsafe to change lanes. Before
making a lane change, check the
SBZA display, check mirrors, glance
over your shoulder, and use the turn
signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror SBZA displays will
briefly come on to indicate the
system is operating. When the
vehicle is in a forward gear, the left-
or right-side mirror display will light
up if a moving vehicle is detected in
that blind zone. If the turn signal is
activated in the same direction of a
detected vehicle, this display will
flash as an extra warning not to
change lanes.
SBZA can be disabled through
vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0116. If SBZA is disabled by the driver,
the SBZA mirror displays will not
light up.
When the System Does Not
Seem to Work Properly
SBZA displays may not come on
when passing a vehicle quickly or
for a stopped vehicle. SBZA may
alert to objects attached to the
vehicle, such as a bicycle, or object
extending out to either side of the
vehicle. This is normal system
operation; the vehicle does not need
service.
SBZA may not always alert the
driver to vehicles in the side blind
zone, especially in wet conditions.
The system does not need to be
serviced. The system may light up
due to guardrails, signs, trees,
shrubs, and other non-moving
objects. This is normal system
operation; the vehicle does not need
service.
SBZA may not operate when the
SBZA sensors in the left or right
corners of the rear bumper are
covered with mud, dirt, snow, ice,

.To check the P (Park)
mechanism's holding ability:
With the engine running, shift to
P (Park). Then release the
parking brake followed by the
regular brake.
Contact your dealer if service is
required.
Wiper Blade Replacement
Windshield wiper blades should be
inspected for wear and cracking.
Replacement blades come in
different types and are removed in
different ways. For proper type and
length, see Maintenance
Replacement Parts 0296.
To replace the windshield wiper
blade: 1. Pull the windshield wiper assembly away from the
windshield.
2. Lift up on the latch in themiddle of the wiper blade
where the wiper arm attaches.
3. With the latch open, pull the wiper blade down toward the
windshield far enough to
release it from the J-hooked
end of the wiper arm.
4. Remove the wiper blade. Allowing the wiper blade arm to
touch the windshield when no
wiper blade is installed could
damage the windshield. Any
damage that occurs would not
be covered by the vehicle warranty. Do not allow the
wiper blade arm to touch the
windshield.
5. Reverse Steps 1–3 for wiper blade replacement.
Windshield Replacement
HUD System
The windshield is part of the HUD
system. If the windshield needs to
be replaced, be sure to get one that
is designed for HUD or the HUD
image may look out of focus.
Driver Assistance Systems
If the windshield needs to be
replaced and the vehicle is
equipped with a front camera sensor
for the Driver Assistance Systems, a
GM replacement windshield is
recommended. The replacement
windshield must be installed
according to GM specifications for
proper alignment. If it is not, these
systems may not work properly, they
may display messages, or they may
not work at all. See your dealer for
proper windshield replacement.

254 Vehicle Care
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity. See
Vehicle Load Limits0160.
How the vehicle is loaded
affects vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.
When to Check
Check the pressure of your tires
once a month or more.
How to Check
Use a good quality pocket-type
gauge to check the tire
pressure. Proper tire inflation
cannot be determined by looking
at the tire. Check the tire
inflation pressure when the tires are cold, meaning the vehicle
has not been driven for at least
three hours or no more than
1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get the pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure in high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would
not be covered by the vehicle
warranty.
Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds, 255 km/h
(155 mph) or higher, puts
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
This could cause a crash, and
you or others could be killed.
Some high-speed rated tires
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle
to be driven at high speeds, make
sure the tires are rated for
high-speed operation, are in
excellent condition, and are set to
the correct cold tire inflation
pressure for the vehicle load.
