The vehicle may not pass
inspection if:
.The light is on when the
engine is running.
.The light does not come on
when the ignition is in
Service Mode.
.Critical emission control
systems have not been
completely diagnosed. If this
happens, the vehicle would
not be ready for inspection
and might require
several days of routine
driving before the system is
ready for inspection. This
can happen if the 12-volt
battery has recently been
replaced or run down, or if
the vehicle has been
recently serviced.
See your dealer if the vehicle
will not pass or cannot be
made ready for the test.
Brake System
Warning Light
MetricEnglish
This light comes on briefly
when the vehicle is turned on
to show that the light is
working. If it does not come on
then, have it fixed so it will be
ready to warn you if there is a
problem.
If the light comes on and stays
on, there is a brake problem.
Have the brake system
inspected right away. This
light may come on if the brake
fluid is low. See Brake Fluid
0 398.
If the light comes on while
driving, pull off the road and
stop carefully. The brake
system has electric brake
boost. Vehicle speed may be limited when the brake system
warning light comes on. The
brake pedal might be harder to
push, or the brake pedal may
go closer to the floor. It could
take longer to stop. If the light
is still on, have the vehicle
towed for service. See

{Warning
The brake system might not
be working properly if the
brake system warning light
is on. Driving with the brake
system warning light on can
lead to a crash. If the light is
still on after the vehicle has
been pulled off the road and
carefully stopped, have the
vehicle towed for service.

variety of programming and
commercial-free music, coast
to coast, in digital-quality
sound. In the U.S., see
www.siriusxm.com or call

content and listening
recommendations, OnStar
Connected Access is required.
Connected vehicle services

Reference the SiriusXM user
guide for use and subscription
information.
Radio Reception
Unplug electronic devices
from the accessory power
outlets if there is interference
or static in the radio.
FM
FM signals only reach about 16
to 65 km (10 to 40 mi).
Although the radio has a
built-in electronic circuit that
automatically works to reduce
interference, some static can
occur, especially around tall
buildings or hills, causing the
sound to fade in and out.
AM
The range for most AM
stations is greater than for
FM, especially at night. The
longer range can cause station
frequencies to interfere with
each other. Static can also
occur when things like storms
and power lines interfere with
radio reception. When this
happens, try reducing the
treble on the radio.

Warning (Continued)
perform these procedures
properly could cause
malfunction, potentially
resulting in death, personal
injury, or damage to the
vehicle or property. Do not
attempt to perform these
adjustments or procedures
unless properly qualified.
{Warning
Prior to each track event
and again before returning
to public roads, tighten the
wheel nuts with a torque
wrench to the proper torque
specification. Wheel nuts
that are improperly or
incorrectly tightened can
cause the wheels to become
loose or come off, resulting
in a crash. See Capacities
and Specifications0480 for
wheel nut torque
specifications.
Caution
Low oil levels can damage
the engine. If using the
vehicle for competitive
driving, the engine may use
more oil than it would with
normal use. Check the oil
level often during
competitive driving.
Competitive Driving Mode can
be selected. See Driver Mode
Control 0292.
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.
