Performance Shifting
If the vehicle has this feature, it can detect a change in
driving patterns. If you make an aggressive driving
maneuver, the vehicle’s transmission automatically
shifts to the lowest possible gear to maximize vehicle
performance. The vehicle will automatically return
to normal operation when you return to normal driving
patterns.
Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver door.
To set the parking brake, hold the regular brake pedal
down, then push the parking brake pedal down.If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have the vehicle serviced.
A warning chime will sound if the parking brake is set, the
ignition is on, and the vehicle speed is greater than 5 mph
(8 km/h). The brake light will come on and stay on until
the parking brake is released. SeeBrake System
Warning Light on page 3-56for more information.
To release the parking brake, hold the regular brake
pedal down, then push the parking brake pedal down.
When you lift your foot off the parking brake pedal,
the pedal will follow your foot to the released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-28.

How the System Works
When the vehicle is started, both outside mirror displays
will briey come on to indicate that the system is
operating. While driving forward, the left or right side
mirror SBZA display will light up if a vehicle is detected
in that blind zone. If you activate a turn signal and a
vehicle has been detected on the same side, the SBZA
display will ash to give you extra warning not to
change lanes.
SBZA displays do not come on while the vehicle is
approaching or passing other vehicles. At speeds
greater then 20 mph (32 km/h), SBZA displays may
come on when a vehicle you have passed remains in
or drops back into the detection zone.SBZA can be disabled through the Driver Information
Center (DIC). SeeDriver Information Center (DIC)
on page 3-67for more information. If the SBZA
is disabled by the driver, the SBZA mirror displays
will not light up during normal driving.
When the System Does Not Seem To
Work Properly
Occasional missed alerts can occur under normal
circumstances and will increase in wet conditions.
The system does not need to be serviced due to an
occasional missed alert. The number of missed
alerts will increase with increased rainfall or road spray.
If the SBZA displays do not light up when the system
is on and vehicles are in the blind zone, the system may
need service. Take the vehicle to your dealer/retailer.
SBZA is designed to ignore stationary objects; however,
the system may occasionally light up due to guard
rails, signs, trees, shrubs, and other stationary objects.
This is normal system operation, the vehicle does
not need service. Left Side Mirror

SBZA does not operate when the left or right corners
of the rear bumper are covered with mud, dirt, snow, ice,
slush, or in heavy rainstorms. For cleaning instructions,
seeWashing Your Vehicle on page 5-90. If the DIC
still displays the SIDE BLIND ZONE SYSTEM
UNAVAILABLE message after cleaning the bumper,
see your dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to the vehicle, or a bicycle or object is extending out
to either side of the vehicle.
When SBZA is disabled for any reason other than the
driver turning it off, the driver will not be able to turn
SBZA back on using the DIC. The SIDE BLIND ZONE
ALERT ON option will not be selectable if the
conditions for normal system operation are not met.
Until normal operating conditions for SBZA are met,
you should not rely upon SBZA while driving.SBZA Error Messages

How the System Works
LDW uses a camera located between the inside rearview
mirror and the windshield to detect the lane markings.
@(Lane Departure Warning):To turn LDW on and off,
press the LDW control, located by the exterior headlamp
control. An indicator on the control will light to indicate
that LDW is on.
When the vehicle is started, the LDW symbol, located in
the instrument panel cluster, will briey come on to
indicate that the light is operational.LDW only operates at speeds of 35 mph (56 km) or
greater. If LDW is turned on when traveling at these
speeds, the LDW symbol will appear green if the system
detects a left or right lane marking. This symbol will
change to amber and ash and three beeps will sound if
you cross a detected lane marking without using the
turn signal.
If the LDW symbol does not appear, LDW is not currently
operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume underDIC Vehicle Customization on page 3-86
for more information.
When the System Does Not Seem To
Work Properly
The LDW symbol will not appear when the system is
having difficulty seeing the lines on the road or if
the view of the camera on the windshield is blocked
with mud, dirt, snow, ice, or slush, if the windshield
is damaged, or when weather limits visibility, such as
while driving in fog, rain, or snow conditions. This is
normal operation, the vehicle does not need service.
For cleaning instructions, seeWashing Your Vehicle
on page 5-90.
