tow bar BUICK LUCERNE 2009 Owner's Manual

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, seeWashing Your
Vehicle on page 5-96.
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/retailer 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
15 mph (25 km/h), take the vehicle to your dealer/retailer.

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 oor carpet and carpeted oor mats.
For any soil, always try to remove it rst 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.
