tow bar BUICK LUCERNE 2010 Owner's Manual

URPA operates only at speeds less than 8 km/h
(5 mph). If the vehicle is above this speed, the red light
on the rear display will flash.
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.
A single beep will sound the first time an object is
detected between 1 m (40 in) and 2.5 m (8 ft) away.
Beeping will occur continuously when the vehicle is at
0.6 m (23 in) or closer to an object.
The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:Description Metric English
amber light 2.5 m 8 ft
amber/amber lights 1.0 m 40 in
amber/amber/red lights and continuous beeping for five seconds 0.6 m 23 in
amber/amber/red lights

beeping for five seconds 0.3 m 1 ft
The system can be disabled through the Driver
Information Center (DIC). See
“Park Assist”underDIC
Operation and Displays
on page 4‑47for more
information.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved
into R (Reverse). This occurs 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 6‑104.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached 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 25 km/h (15 mph), take the vehicle to your dealer.

Do not clean the vehicle using:
.A knife or any other sharp object to remove a soil
from any interior surface.
.A stiff brush. It can cause damage to the vehicle's
interior surfaces.
.Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
.Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide. Use only
mild, neutral-pH soaps.
.Too much cleaner that saturates the upholstery.
.Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle's interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on floor carpet and carpeted floor mats. For any
soil, always try to remove it first with plain water or club
soda. Before cleaning, gently remove as much of the
soil as possible using one of the following techniques:
.For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the paper
towel until no more can be removed.
.For solid dry soils: remove as much as possible
and then vacuum.
To clean: 1. Saturate a lint-free, clean white cloth with water or club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild soap solution and repeat the cleaning process that
was used with plain water.
