2010 BUICK LUCERNE warning

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 4‑36for 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.

Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is firmly set before you leave it. See
Parking
Brake
on page 3‑26for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then
it is difficult to shift out of P (Park). To prevent torque
lock, set the parking brake and then shift into P (Park).
To find out how, see “Shifting Into Park”in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).

Engine Exhaust
{WARNING:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to CO
can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airflow or tail pipes).
.The exhaust smells or sounds strange or
different.
.The exhaust system leaks due to corrosion or
damage.(Continued)
WARNING: (Continued)
.The vehicle’s exhaust system has been
modified, damaged or improperly repaired.

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains
Carbon Monoxide (CO) which cannot be seen or
smelled. It can cause unconsciousness and even
death. Never run the engine in an enclosed area
that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑31.
{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).

Side Blind Zone Alert (SBZA)
If the vehicle has the Side Blind Zone Alert (SBZA)
system, seeSide Blind Zone Alert (SBZA)on
page 3‑39.
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 4‑65for 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 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 if they are too close
or far from the vehicle
.Children, pedestrians, bicyclists, or pets.
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind (Continued)
WARNING: (Continued)
the vehicle before backing up. While backing, be
sure to look for objects and check the vehicle's
mirrors.
The display is located on
the rear shelf, below the
rear window, and can be
seen by looking over your
right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briefly
illuminates to indicate the system is working.
3-37

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.
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.
