StabiliTrak®System
The vehicle may have a vehicle
stability enhancement system called
StabiliTrak. It is an advanced
computer-controlled system that
assists with directional control of the
vehicle in difficult driving conditions. StabiliTrak activates when the
computer senses a difference
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure to the
vehicle brakes to help steer the
vehicle in the intended direction.
StabiliTrak comes on automatically
whenever the vehicle is started.
To assist with directional control
of the vehicle, the system should
always be left on.
When StabiliTrak activates,
d
flashes on the instrument panel.
A noise may be heard or vibration
may be felt in the brake pedal.
This is normal. Continue to steer the
vehicle in the intended direction.
See
Traction Control System (TCS)/
StabiliTrak
®Light on page 5‑18 for
more information. If a problem is detected with
StabiliTrak, SERVICE
STABILITRAK is displayed on the
Driver Information Center (DIC).

indicate that URPA is off. The
message disappears after a short
period of time.
Turning the System On and Off
The URPA system can be turned on
and off using the park assist button
located next to the radio.
The park assist button lights up

URPA defaults to the on setting
each time the vehicle is started.
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 Driver
Information Center (DIC) on
page 5‑22 for more information.
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 10‑77.
.An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed and
URPA detects no objects of
interest, the URPA will return to
normal operation.
.The vehicle's 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.
If the system is still disabled after
checking all conditions listed above
and driving forward at least 40 km/h
(25 mph), take the vehicle to your
dealer.

Notice:Use only engine oil that
is approved to the dexos
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos
specification will show the dexos
symbol on the container. Failure
to use the recommended engine
oil or equivalent can result in
engine damage not covered by
the vehicle warranty. If you are
unsure whether the oil is
approved to the dexos
specification, ask your service
provider.
Use of Substitute Engine Oils if
dexos is unavailable: In the event
that dexos‐approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil
displaying the API Starburst symbol
and of SAE 5W-30 viscosity grade.
Use of oils that do not meet the
dexos specification, however, may
result in reduced performance under
certain circumstances. Specification (2.0L Turbo Engine)
Use and ask for engine oils with
the dexos certification mark. Oils
meeting the requirements of the
vehicle should have the dexos
certification mark on the container.
This certification mark indicates that
the oil has been approved to the
dexos specification.
This vehicle was filled at the factory
with dexos‐approved engine oil.
Notice:
Use only engine oil
that is approved to the dexos
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine
oils approved to the dexos
specification will show the dexos
symbol on the container. Failure
to use the recommended engine oil or equivalent can result in
engine damage not covered
by the vehicle warranty. If you
are unsure whether the oil
is approved to the dexos
specification, ask your service
provider.
Use of Substitute Engine Oils if
dexos is unavailable for top‐up
only: Engine oil not meeting the
dexos specification or equivalent
should not be used for an oil
change. In the event that
dexos‐approved engine oil is not
available for maintaining proper oil
level, however, you may use
substitute engine oil displaying
the API Starburst symbol and of
SAE 5W-30 viscosity grade.
Extensive use of oils that do not
meet the dexos specification,
however, may result in reduced
performance or engine damage
under certain circumstances.

Black plate (12,1)Buick Regal Owner Manual - 2011
10-12 Vehicle Care
Maintaining the proper oil level is
very important. However, if you use
a substitute oil for any reason, we
recommend that you perform a
complete oil change back to dexos
as soon as possible to protect the
engine and maintain the engine's
peak performance.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity oils such as
SAE 10W‐30, 10W‐40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below−29°C(−20°F), an SAE 0W-30 oil should
be used. An oil of this viscosity
grade will provide easier cold
starting for the engine at extremely
low temperatures. When selecting
an oil of the appropriate viscosity
grade, be sure to always select an
oil that meets the required
specification, dexos. See
“Specification”
earlier in this section
for more information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos
specification and displaying the
dexos certification mark are all that
is needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.

Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer service department and have
it repaired as soon as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer
service department. Contact your
dealer for additional information.
The procedure can be found in the
service manual. To purchase a
service manual, see Service
Publications Ordering Information
on page 13‑11.
Change the fluid and filter at the
intervals listed in Scheduled
Maintenance on page 11‑2, and be sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑6.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer service department and
have it repaired as soon as
possible. See
Recommended Fluids
and Lubricants on page 11‑6 for the
proper fluid to use.
Hydraulic Clutch
For vehicles with a manual
transmission, it is not necessary to
regularly check brake/clutch fluid
unless there is a leak suspected.
Adding fluid will not correct a leak.
A fluid loss in this system could
indicate a problem. Have the
system inspected and repaired.
