the fluid life, additional maintenance is
recommended in the Maintenance Schedule.
See Maintenance Schedule 0306.
The Fluid Life display must be reset after
each fluid change. It will not reset itself. Do
not reset the Fluid Life display accidentally
at any time other than when the fluid has
just been changed. It cannot be reset
accurately until the next fluid change. To
reset, see Dual Clutch Transmission Fluid Life
System 0249.

Teen Driver Speed Limiter :Limits the
maximum speed of the vehicle. When the
speed limiter is turned on and the vehicle is
started with a Teen Driver key, the DIC
displays a message that the top speed is
limited.
On certain vehicles, when the Speed Limiter
is turned ON, the vehicle’s maximum
acceleration will be limited. The DIC will
display a message that the acceleration is
limited.
Teen Driver Speed Warning : Displays a
warning in the DIC when exceeding a
selectable speed. Turn the speed warning on
or off and choose the desired speed warning
level. The speed warning does not limit the
speed of the vehicle. On some infotainment
systems, touch Set Teen Driver Speed
Warning to set the warning speed.
Set Teen Driver Speed Warning : Choose the
desired speed warning level. The speed
warning does not limit the speed of the
vehicle.
SiriusXM Explicit Content Filter : Allows the

ON or OFF. When ON, the teen driver will
not be able to listen to SiriusXM stations that contain explicit content, and the Explicit
Content Filter selection in the Audio Settings
will be unavailable for change.
When Teen Driver is Active:
.If equipped, the radio will mute when the
driver seat belt, and in some vehicles the
front passenger seat belt, is not buckled.
The audio from any device paired to the
vehicle will also be muted.
.An object placed on the front passenger
seat, such as a briefcase, handbag,
grocery bag, laptop, or other electronic
device, could cause the passenger sensing
system to falsely sense an unbuckled
front passenger and mute the radio.
If this happens, remove the object from
the seat. See
Passenger Sensing System
0 56.
.Some safety systems, such as Automatic
Emergency Braking, if equipped, cannot
be turned off.
.The gap setting for Adaptive Cruise
Control and alert timing for Forward
Collision Alert, if equipped, cannot be
changed.
.When trying to change a safety feature
that is not configurable in Teen Driver,
the feature may be grayed out or
removed from the infotainment menu, or the DIC will display a message
indicating that Teen Driver is active and
the action is not available.
.Super Cruise, if equipped, is not available.
.Enhanced Low Fuel Warning
(if equipped)
–When the vehicle is low
on fuel, the low fuel light on the
instrument cluster flashes and the DIC
low fuel warning cannot be dismissed.
.Do not tow a trailer if equipped with
Automatic Emergency Braking.
Report Card
The vehicle owner must secure the driver’s
consent to record certain vehicle data when
the vehicle is driven with a registered Teen
Driver key. There is one Report Card per
vehicle. Data is only recorded when a
registered Teen Driver key is used to
operate the vehicle.
The Report Card data is collected from the
time Teen Driver is activated or the last
time the Report Card was reset. The
following items may be recorded:
.Distance Driven –the total distance
driven.
.Maximum Speed –the maximum vehicle
speed detected.

174 Driving and Operating
Engine Cooling
If reduced performance is experienced during
track events or competitive driving, turning
off the A/C will help to improve engine
performance.
Maintain a mixture of 40% DEX-COOL
coolant and 60% clean, drinkable water to
optimize engine performance.
Fuel
Unleaded gasoline, rated at 93 octane or
higher, is required.
Caution
Some high octane fuels contain additives
and compounds that may damage the
vehicle and void the vehicle warranty. See
Prohibited Fuels0227.
Dual Clutch Transmission (DCT) Fluid
The transmission fluid and external canister
filter should be changed after every 24 hours
of track use. Change the fluid and external
canister filter as soon as possible if
prompted by the transmission fluid life
monitor that remaining fluid life is low. Stingray
Add an additional 2 L (2 qt) of DCT
transmission fluid before track use. It is not
required to remove the additional 2 L (2 qt)
of DCT fluid after the track event.
Any transmission level set or change should
be performed at your dealer.
Z06
Additional transmission fluid is not required
for the Z06. The Z06 comes track ready
from the factory.
Brakes
Battery Disconnect
Disconnect the battery before servicing the
hydraulic brake system. It is critical to
disconnect the battery before bleeding the
system, replacing the pads, or any other
work. The battery must be disconnected to
prevent the brake master cylinder from
pressurizing the hydraulic system during its
automated self diagnostic tests that can
occur when a door is opened or the remote
key is present.
{Warning
To avoid personal injury and/or vehicle
damage, always disconnect the battery
before performing service work on the
hydraulic brake system. Bleeding the
brake system with the battery connected
can lead to the system diagnosing a leak
or air in the braking system. A Diagnostic
Trouble Code (DTC) may set and vehicle
speed may be limited.
Brake Fluid
Replace existing brake fluid with a qualified
high performance DOT 4 brake fluid from a
sealed container. Brake fluid with a dry
boiling point >310 °C (590 °F) is qualified.
If high performance brake fluid is used,
replace it with GM approved brake fluid
before driving on public roads. If high
performance brake fluid is in the vehicle and
the age of the brake fluid is over a month
old or unknown, replace the brake fluid
before track events and competitive driving.
Do not use silicone or DOT-5 brake fluids.
Check the fluid level before each competitive
driving event.

306 Service and Maintenance
Because of the way people use vehicles,
maintenance needs vary. There may need to
be more frequent checks and services. The
Additional Required Services - Normal are for
vehicles that:
.Carry passengers and cargo within
recommended limits on the Tire and
Loading Information label. SeeVehicle
Load Limits 0186.
.Are driven on reasonable road surfaces
within legal driving limits.
.Use the recommended fuel. See
Recommended Fuel 0227.
Refer to the information in the Maintenance
Schedule Additional Required Services -
Normal chart.
The Additional Required Services - Severe are
for vehicles that are:
.Mainly driven in heavy city traffic in hot
weather.
.Mainly driven in hilly or mountainous
terrain.
.Used for high speed or competitive
driving.
.Used for taxi, police, or delivery service.
Refer to the information in the Maintenance
Schedule Additional Required Services -
Severe chart.
{Warning
Performing maintenance work can be
dangerous and can cause serious injury.
Perform maintenance work only if the
required information, proper tools, and
equipment are available. If they are not,
see your dealer to have a trained
technician do the work. See Doing Your
Own Service Work 0234.
Maintenance Schedule
Tire Rotation and Required Services
Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform
wear for all tires. The first rotation is the
most important.
Anytime unusual wear is noticed, rotate the
tires as soon as possible, check for proper
tire inflation pressure, and check for
damaged tires or wheels. If the unusual
wear continues after the rotation, check the
wheel alignment. See When It Is Time for
New Tires 0285 and
Wheel Replacement 0288.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 308.
.Lubricate body components. See Exterior
Care 0296.
Additional Required Services –Normal
Service
Every 12 000 km (7,500 mi)
.Check engine oil level and oil
life percentage. If needed, change engine
oil and filter, and reset oil life system. Or
when the CHANGE ENGINE OIL SOON
message displays, have the engine oil and
filter changed within the next 1 000 km
(600 mi). If driven under the best
conditions, the engine oil life system may
not indicate the need for vehicle service
for up to a year. The engine oil and filter
must be changed at least once a year and
the oil life system must be reset. Your
trained dealer technician can perform this
work. If the engine oil life system is reset
accidentally, service the vehicle within
5 000 km (3,000 mi) since the last service.
Reset the oil life system when the oil is
changed. See Engine Oil Life System
0 248.
