Pairing
A Bluetooth enabled cell phone must be paired to the
in‐vehicle Bluetooth system first and then connected to
the vehicle before it can be used. See the cell phone
manufacturers user guide for Bluetooth functions before
pairing the cell phone. If a Bluetooth phone is not
connected, calls will be made using OnStar
®Hands‐
Free Calling, if available. Refer to the OnStar owner's
guide for more information.
Pairing Information:
.Up to five cell phones can be paired to the
in‐vehicle Bluetooth system.
.The pairing process is disabled when the vehicle is
moving.
.The in‐vehicle Bluetooth system automatically links
with the first available paired cell phone in the
order the phone was paired.
.Only one paired cell phone can be connected to
the in‐vehicle Bluetooth system at a time.
.Pairing should only need to be completed once,
unless changes to the pairing information have
been made or the phone is deleted.
To link to a different paired phone, see Linking to a
Different Phone later in this section.
Pairing a Phone
1. Press and holdb gfor two seconds. The system
responds with “Ready”followed by a tone.
2. Say “Bluetooth”. The system responds with
“Bluetooth ready” followed by a tone.
3. Say “Pair”. The system responds with instructions
and a four digit PIN number. The PIN number will
be used in Step 4.
4. Start the Pairing process on the cell phone that will be paired to the vehicle. Reference the cell phone
manufacturers user guide for information on this
process.
Locate the device named “General Motors”in the
list on the cellular phone and follow the instructions
on the cell phone to enter the four digit PIN
number that was provided in Step 3.
5. The system prompts for a name for the phone. Use a name that best describes the phone. This name
will be used to indicate which phone is connected.
The system then confirms the name provided.
6. The system responds with “
been successfully paired” after the pairing process
is complete.
7. Repeat Steps 1 through 7 for additional phones to be paired.

Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps prevent
a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor or
clicking noise might be heard while this test is going on,
and it might even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with
ABS, this warning light
stays on. See Antilock
Brake System (ABS)
Warning Light
on
page 4‑37.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help the
driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to
get a foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, there will not be enough time to apply the
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let antilock work. A motor or clicking
noise might be heard and the brake pedal might be felt
to move a little during a stop, but this is normal.

Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle 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.
Selective Ride Control
The vehicle may have a ride control system called
Magnetic Selective Ride Control. The system provides
the following performance benefits:
.Reduced Impact Harshness
.Improved Road Isolation
.Improved High-Speed Stability
.Improved Handling Response
.Better Control of Body Ride Motions
Except ZR1
This knob is located on
the center console. Turn it
to select the suspension
of your choice.
TOUR : Use for normal city and highway driving.
This setting provides a smooth, soft ride.
SPORT : Use where road conditions or personal
preference demand more control. This setting provides
more “feel”, or response to the road conditions.
The setting can be changed at any time. Based on road
conditions, steering wheel angle and the vehicle speed,
the system automatically adjusts to provide the best
handling while providing a smooth ride. The Tour and
Sport modes will feel similar on a smooth road. Select a
new setting whenever driving conditions change.

Oils meeting these
requirements should have
the starburst symbol on
the container. This symbol
indicates that the oil has
been certified by the
American Petroleum
Institute (API).
This vehicle's engine was filled at the factory with a
Mobil 1
®synthetic oil meeting all requirements for this
vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
might 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 / Engine Oil
Flushes
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM Standard
GM4718M are all that is needed for good performance
and engine protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that indicates when to
change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not
on mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system must
be reset every time the oil is changed.
