death. Never run the engine in an enclosed
area that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑30.
{WARNING:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake firmly set. The
vehicle can roll. Do not leave the vehicle when the
engine is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you
are on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. See Shifting Into Park on page 3‑27.
If parking on a hill and pulling a trailer, see Towing a
Trailer on page 5‑25.
Mirrors
Automatic Dimming Rearview Mirror
The vehicle may have an automatic dimming inside
rearview mirror with OnStar®and/or a compass
display. Automatic dimming reduces the glare from the
headlamps of the vehicle behind you. The dimming
feature comes on and the indicator light illuminates
each time the vehicle is started.
Vehicles with OnStar have three additional control
buttons located at the bottom of the mirror. See your
dealer for more information on the system and how to
subscribe to OnStar. See the OnStar
®owners guide for
more information about the services OnStar provides.
O(On/Off): Press to turn the dimming feature and/or
compass display on or off.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror. Use a
soft towel dampened with water.

Side Blind Zone Alert (SBZA)
If the vehicle has the Side Blind Zone Alert (SBZA)
system, seeSide Blind Zone Alert (SBZA)on
page 3‑36.
Park Tilt Mirrors
If the vehicle has memory mirrors, the outside mirrors
have park tilt mirrors . This feature tilts the driver's side
and passenger side mirror to a factory programmed
position when the vehicle is in R (Reverse). This feature
may be useful in allowing you to view the curb when
you are parallel parking.
When the vehicle is shifted out of R (Reverse) and
either a five second delay has occurred, or the ignition
is turned to LOCK/OFF, the driver and passenger side
mirrors return to their original position.
See DIC Vehicle Customization
on page 4‑58for more
information.
Outside Convex Mirror
{WARNING:
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 the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror's surface is curved so more can be seen from the
driver seat.
Outside Heated Mirrors
For vehicles with heated mirrors:
<(Rear Window Defogger): Press to heat the
mirrors.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking Assist
(URPA) system, it operates at speeds less than 8 km/h
(5 mph), and assists the driver with parking and
avoiding objects while in R (Reverse). The sensors on
the rear bumper are used to detect the distance to an
object up to 2.5 m (8 ft) behind the vehicle, and at least
25 cm (10 in) off the ground.
{WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
.Objects that are below the bumper,
underneath the vehicle, or too close or far
from the vehicle.
.Children, pedestrians, bicyclists, or pets.(Continued)
WARNING: (Continued)
If you do not use proper care before and while
backing, vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle's mirrors.
How the System Works
URPA comes on automatically when the shift lever
is moved into R (Reverse). A single tone sounds to
indicate the system is working.
URPA operates only at speeds less than
8 km/h (5 mph).
An obstacle is indicated by audible beeps. The interval
between the beeps becomes shorter as the vehicle gets
closer to the obstacle. When the distance is less than
30 cm (12 in) the beeps are continuous.
To be detected, objects must be at least 25 cm (10 in)
off the ground and below trunk level. Objects must
also be within 2.5 m (8 ft) from the rear bumper. This
distance may be less during warmer or humid weather.

The system can be disabled through the Driver
Information Center (DIC). See“Park Assist”under
DIC Operation and Displays
on page 4‑42for more
information.
When the System Does Not Seem to
Work Properly
SERVICE PARK ASSIST: If this message occurs, take
the vehicle to your dealer to repair the system.
PARK ASSIST OFF: If the URPA system does not
activate due to a temporary condition, the message
displays on the DIC, see DIC Operation and Displays
on page 4‑42for more information. This can occur
under the following conditions:
.The driver disables the system.
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, see Washing
Your Vehicle on page 6‑102.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle. Once the object is removed, URPA
will return to normal operation.
.A tow bar is attached to the vehicle.
.The vehicle's bumper is damaged. Take the vehicle
to your dealer to repair the system.
.Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 40 km/h (25 mph), take the vehicle to your dealer.
Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the
system.
{WARNING:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
.Vehicles outside the side blind zones which
may be rapidly approaching.
.Pedestrians, bicyclists, or animals. (Continued)
3-36

Black plate (37,1)Buick Lucerne Owner Manual - 2011
WARNING: (Continued)
Failure to use proper care when changing lanes
may result in damage to the vehicle, injury,
or death. Always check the outside and rearview
mirrors, glance over your shoulder, and use the
turn signal before changing lanes.
When the system detects a vehicle in the side blind
zone, amber SBZA displays will light up in the side
mirrors. This indicates that it may be unsafe to change
lanes. Before making a lane change, always check the
SBZA display, check the outside and rearview mirrors,
look over your shoulder for vehicles and hazards, and
use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of approximately one
lane over from both sides of the vehicle, 3.5 m (11 ft).
This zone starts at each side mirror and goes back
approximately 5 m (16 ft). The height of the zone is
approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) off
the ground.
The SBZA detection zones do not change if the vehicle
is towing a trailer. So be extra careful when changing
lanes while towing a trailer.

Black plate (38,1)Buick Lucerne Owner Manual - 2011
How the System Works
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside mirror displays
will briefly 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 flash 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). See
Driver Information Center (DIC)
on
page 4‑42for 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.
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.
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,
see Washing Your Vehicle
on page 6‑102. If the DIC still
displays the SIDE BLIND ZONE SYS. UNAVAILABLE
message after cleaning the bumper, see your dealer.

Lane Departure Warning (LDW)
The vehicle may have a Lane Departure Warning
(LDW) system. Read this entire section before using the
system.
{WARNING:
The Lane Departure Warning (LDW) system does
not steer the vehicle and is only an aid to help
you stay in your driving lane. The LDW system
may not:
.Provide you with enough time to avoid a lane
change collision.
.Be loud enough for you to hear the warning
beeps.
.Work properly under bad weather conditions
or if the windshield is not kept clean.
.Detect lane markings and will not detect road
edges.
.Warn you that your vehicle is crossing a lane
marking if the system does not detect the lane
marking.(Continued)
WARNING: (Continued)
LDW will indicate the system is working whenever
it detects either the left or right lane marking. So if
you depart on the side of the lane that LDW is not
detecting, LDW will not warn you.
If you do not carefully maintain your vehicle
position within the lane, vehicle damage, injury,
or death could occur. Even with LDW, always
keep your attention on the road and maintain
proper vehicle position within the lane. Always
keep the windshield clean and do not use LDW in
bad weather conditions.
When the vehicle crosses a detected lane marking, the
LDW symbol will flash and you will hear three beeps.
LDW will not warn you if the turn signal is on or if you
make a sharp maneuver. Before making a lane change,
check the vehicle's mirrors, glance over your shoulder
for vehicles and hazards, and start the turn signal
before changing lanes.
3-40

Black plate (41,1)Buick Lucerne Owner Manual - 2011
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 briefly 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 flash 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 under
DIC Vehicle Customization
on page 4‑58for 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, see Washing Your Vehicle
on
page 6‑102.
LDW warnings may occasionally occur due to tar
marks, shadows, cracks in the road, or other road
imperfections. This is normal system operation, the
vehicle does not need service.

Floor Mats
{WARNING:
If a floor mat is the wrong size or is not properly
installed, it can interfere with the accelerator pedal
and/or brake pedal. Interference with the pedals
can cause unintended acceleration and/or
increased stopping distance which can cause a
crash and injury. Make sure the floor mat does not
interfere with the accelerator or brake pedal.
Use the following guidelines for proper floor mat usage.
.The original equipment floor mats were designed
for your vehicle. If the floor mats need replacing, it
is recommended that GM certified floor mats be
purchased. Non-GM floor mats may not fit properly
and may interfere with the accelerator or brake
pedal. Always check that the floor mats do not
interfere with the pedals.
.Use the floor mat with the correct side up. Do not
turn it over.
.Do not place anything on top of the driver side
floor mat.
.Use only a single floor mat on the driver side.
.Do not place one floor mat on top of another.
The driver side floor mat is held in place by two hooks.
Removing and Replacing the Floor Mats
1. Pull up on the rear of the mat to remove it from the hooks.
2. Reinstall the floor mat by lining up the openings in the floor mat over the hooks and push it down into
position.
