Fuel; Fuel Additives - Chevrolet 2012 Malibu Owner's Manual

When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
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, this message
displays on the DIC. This can occur
under the following conditions:
.
The driver has disabled 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 Exterior Care
on page 9‑70.
.
The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
.
An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed,
URPA will return to normal
operation.
.
The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.
Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Driving and Operating

Fuel

Use of the recommended fuel is
an important part of the proper
maintenance of this vehicle, keeps
the engine clean, and maintains
optimum vehicle performance.

Fuel Additives

Petrol should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly.
Some petrol does not contain
sufficient quantities of additive to
keep fuel injectors and intake valves
clean. To make up for this lack of
detergency, it is recommended that
GM Fuel System Treatment PLUS
(GM Part No. 88861011) be added
to the fuel tank at every engine oil
change or every 15 000 km,
whichever occurs first.
