Clearing the System
Unless information is deleted out of the in‐vehicle
Bluetooth system, it will be retained indefinitely. This
includes all saved name tags in the phonebook and
phone pairing information. For information on how to
delete this information, see the above sections on
Deleting a Paired Phone and Deleting Name Tags.

Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of the
vehicle's radio by learning a portion of the Vehicle
Identification Number (VIN). The radio does not operate
and LOCKED displays if the radio is stolen or moved to
a different vehicle.
When the when the ignition is in the off position, a
blinking red light on the upper left side of the radio
indicates that THEFTLOCK
®is armed.

Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
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. For better radio
reception, most AM radio stations boost the power
levels during the day, and then reduce these levels
during the night. 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.
FM Stereo
FM signals only reach about 10 to 40 miles
(16 to 65 km). 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.

For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive.
Medical research shows that alcohol in a person's
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking —driver or
passenger —is in a crash, that person's chance of
being killed or permanently disabled is higher than if
the person had not been drinking.Control of a Vehicle
The following three systems help to control the vehicle
while driving —brakes, steering, and accelerator. At
times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road
can provide. Meaning, you can lose control of the
vehicle. See Traction Control System (TCS)
on
page 5‑6and Active Handling System on page 5‑8.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. See Accessories and
Modifications on page 6‑3.

Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a brake assist feature that responds to
emergency braking by generating additional pressure
and engaging the ABS. When this happens, the brake
pedal will feel easier to push. Just hold the brake pedal
down firmly and let the system work for you. You might
feel the brakes vibrate or notice some noise, but this is
normal. The brakes will return to normal operation after
the brake pedal is released.
Brake assist cannot compensate for unsafe driving
practices and braking effectiveness, itself, depends on
the condition of the road, tires, and brakes and
vehicle mass.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine
power (by closing the throttle and managing engine
spark) to limit wheel spin.
The TRACTION SYSTEM ACTIVE message displays
on the Driver Information Center (DIC) when TCS is
limiting wheel spin. See DIC Warnings and Messages
on page 4‑52. The system may be heard or felt while it
is working, but this is normal.
If cruise control is being used when TCS begins to limit
wheel spin, the cruise control will automatically
disengage. Cruise control may be reengaged when
road conditions allow. See Cruise Control on page 4‑7.

The SERVICE
TRACTION SYSTEM
message and the
TCS warning light will
come on if there is a
problem with TCS.
See DIC Warnings and
Messages on page 4‑52.
When this light and the SERVICE TRACTION SYSTEM
message are on, the system will not limit wheel spin.
Adjust your driving accordingly.
TCS automatically comes on whenever the vehicle is
started. To limit wheel spin, especially in slippery road
conditions, the system should always be left on.
TCS can be turned off if needed. To turn the system off,
press the button located
on the console.
The system can be turned on or off at any time by
pressing the ACTIVE HANDLING button. The DIC will
display the appropriate message when the button
is pushed.
Notice: When traction control is turned off,
or Competitive Driving Mode is active, it is possible
to lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is
possible to cause damage to the transmission.
Do not attempt to shift when the drive wheels do not
have traction. Damage caused by misuse of the
vehicle is not covered. See the warranty book for
additional information.
Adding non‐dealer/non-retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications
on page 6‑3for more information.

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

This knob is located on
the center console. Turn it

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.
