Section 2 Features and Controls
2-1

Outside Automatic Dimming Mirror
If the vehicle is equipped with this feature, the driver’s
side mirror will adjust for the glare of headlamps behind
you. This feature is controlled by the on and off
settings on the automatic dimming rearview mirror.
SeeAutomatic Dimming Rearview Mirror with OnStar
®
on page 2-37.
Outside Curb View Assist Mirror
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist mirror
feature. This feature will allow the passenger’s side
mirror to tilt to a factory programmed position when the
vehicle is in REVERSE (R). This feature may be
useful in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of REVERSE (R) and
a ve-second delay has occurred, the passenger’s side
mirror will return to its original position.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used.
This feature can be enabled/disabled through the
Driver Information Center (DIC). SeeDIC Vehicle
Personalization on page 3-68for more information.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger’s side mirror is convex. A convex mirror’s
surface is curved so more can be seen from the
driver’s seat. This mirror does not have a dimming
feature.
Outside Heated Mirrors
When you operate the rear window defogger, it also
warms both outside mirrors to help clear them of fog or
ice. SeeDual Climate Control System on page 3-30
for more information.

HomeLink®Wireless Control
System Operation
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow Steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
Internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.

Ultrasonic Parking Assist
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at speeds
less than 3 mph (5 km/h). URPA can help you avoid
colliding with objects such as parked vehicles. The
system can detect objects 5 feet (1.5 m) behind your
vehicle and tell you how close those objects are to your
rear bumper.{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.

The traction control system monitors the front brake rotor
temperature. If the traction control system comes on
while the front brake rotors are hot due to heavy use of
braking or previous traction control, the TRACTION
SUSPENDED message will be displayed – but the
system will not turn off right away. It will wait until there is
no longer a current need to limit wheel spin. The
TRACTION READY message should appear when the
brake rotors are no longer hot and the traction control
system will resume normal operation.
Continuous Variable Road Sensing
Suspension (CVRSS)
Your vehicle may have a Continuous Variable Road
Sensing Suspension (CVRSS). CVRSS automatically
adjusts the ride of your vehicle. Automatic ride control is
achieved through a computer used to control and
monitor the suspension system. The controller receives
input from various sensors to determine the proper
system response. If the controller detects a problem
within the system, the DIC will display a SERVICE
SUSPENSION SYS message. SeeDIC Warnings and
Messages on page 3-60for more information. If this
message appears, have your vehicle serviced at
your dealership.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Magnetic Speed Variable Assist
Steering System
This system continuously adjusts the effort you feel
when steering at all vehicle speeds. It provides ease
when parking, yet a rm, solid feel at highway speeds.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your vehicle’s
hazard warning ashers. SeeHazard Warning Flashers
on page 3-6for more information.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.When your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information will tell you next how to use
the jack and change a tire.
