Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features intended to
minimize driver distraction. Technology alone, no
matter how advanced, can never replace your own
judgment. See the Navigation System manual for some
tips to help you reduce distractions while driving.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identication Number
(VIN). If the radio is moved to a different vehicle, it
will not operate and LOCKED will appear on the display.
With THEFTLOCK
®activated, the radio will not
operate if stolen.
Your radio has a blinking indicator light located on the
upper left side of the radio. The indicator light is used
to show that the theft-deterrent feature mode is set.
The blinking indicator light will only ash when the
ignition is in the off position.
Audio Steering Wheel Controls
If your vehicle has this
feature, some audio
controls can be adjusted
at the steering wheel.
They include the
following:
xw(Next/Previous):Press the down or up arrow to
go to the next or to the previous radio station and
stay there. The radio only seeks stations with a strong
signal that are in the selected band.
To scan stations, press and hold either the down or up
arrow for two seconds until SCAN displays and a
beep sounds. The radio goes to a station, plays for a
few seconds, then goes to the next station. Press either
the down or up arrow again to stop scanning.

Competitive Driving Mode
The driver can select this optional handling mode by
pressing the ACTIVE HANDLING button on the
console two times within a ve second time period.
COMPETITIVE DRIVING MODE will be displayed in the
DIC. Competitive Driving Mode allows the driver to have
full control of the rear wheels while the Active Handling
System helps maintain directional control of the vehicle
by selective brake application. This involves less
intervention than with both the Active Handling System
and Traction Control Systems on. The instrument cluster
light will not be on. The Traction Control System will not
be operating. Adjust your driving accordingly.
When you press the ACTIVE HANDLING button again,
or press the Acc. button, the Active Handling and Traction
Control Systems will be on. The TRACTION SYSTEM

wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not
attempt to shift when the rear wheels do not have
traction. Damage caused by misuse of the vehicle is
not covered. See your warranty book for additional
information.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when one of
the rear wheels has no traction and the other does, this
feature will allow the wheel with traction to move the
vehicle.

Changing Engine Oil and Filter
(Z06 Only)
Z06 models have a racetrack-ready dry sump engine
lubrication system. This high-performance system
operates differently than a standard engine lubrication
system and requires a special procedure when changing
the engine oil and lter. Follow this procedure closely
when changing the engine oil and lter.
A. Engine Oil Drain Plugs
B. Seals1. Remove the two engine oil drain plugs from the
bottom of the engine oil pan. One drain plug
drains the external oil tank via the oil transfer supply
line. The other drain plug drains residual oil from
the crankcase sump. Allow the oil to drain.
2. Once the oil has been drained from the engine,
remove the engine oil lter and allow the oil to
drain.
3. Re-install both drain plugs and tighten them to
18 lb ft (25Y).
4. Replace the oil lter and tighten it to 18 lb ft
(25Y). SeeMaintenance Replacement Parts on
page 6-14for the correct lter.
5. Oil is lled through the opening in the top of the
external engine oil tank. Remove the oil ll cap.
6. Add eight quarts (7.6 L) of oil to the oil tank. See
Capacities and Specifications on page 5-107.
7. Install the oil ll cap and insert the dipstick, if
removed.
8. Start the engine and let it run at idle for at least
15 seconds. This will circulate the fresh engine
oil through the lubrication system.
9. Shut off the engine and check the oil level as
described under “Checking Engine Oil (Z06 Only).”
5-21

Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available. You can add substitute oil
designated SAE 5W-30 with the starburst symbol at all
temperatures. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM Standard
GM4718M are all you need for good performance and
engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer that lets you know when
to change the engine oil and lter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.Z06 models have a racetrack-ready dry sump engine
lubrication system. This high-performance system
operates differently than a standard engine lubrication
system and requires a special procedure when changing
the engine oil and lter. SeeEngine Oil on page 5-17.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE ENGINE OIL message will come on. Change
the oil as soon as possible within the next 600 miles
(1 000 km). It is possible that, if you are driving under the
best conditions, the oil life system might not indicate that
an oil change is necessary for over a year. However, the
engine oil and lter must be changed at least once a year
and at this time the system must be reset. Your dealer/
retailer has trained service people who will perform this
work using genuine parts and reset the system. It is also
important to check the oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
