8-6 Climate Controls
Sensors
The solar sensor, located on top
of the instrument panel near the
windshield, monitors the solar heat.
The climate control system uses
the sensor information to adjust
the temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
If the sensor is covered, the
automatic climate control system
may not work properly.
Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
Use the thumbwheels near the air
vents to control the amount of
airflow or to shut off the airflow.
Operation Tips
.Keep all outlets open whenever
possible for best system
performance.
.Keep the paths under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Maintenance
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
SeeMaintenance Schedule on
page 11‑3.
See your dealer regarding
replacement of the filter.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑9.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a yellow
loop. See Engine Compartment
Overview on page 10‑6 for the
location of the engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.

10-10 Vehicle Care
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN withthe engine off.
2. Press the DIC MENU button on the turn signal lever to enter the
Vehicle Information Menu. Use
the thumbwheel to scroll through
the menu items until you reach
REMAINING OIL LIFE.
3. Press the SET/CLR button to reset the oil life at 100%.
4. Turn the ignition to LOCK/OFF.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off and the REMAINING
OIL LIFE 100% message is
displayed. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.
Automatic Transmission
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 and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information.
Black plate (11,1)Buick Verano Owner Manual - 2012 - CRC - 1/10/12
Vehicle Care 10-11
Change the fluid and filter at the
intervals listed inMaintenance
Schedule on page 11‑3, and be
sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
Engine Air Cleaner/Filter
See Engine Compartment Overview
on page 10‑6 for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
scheduled maintenance intervals
and replace it at the first oil change
after each 80 000 km (50,000 mi)
interval. See Maintenance Schedule
on page 11‑3 for more information.
If you are driving in dusty/dirty
conditions, inspect the filter at each
engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains covered with dirt, a new
filter is required.
To inspect or replace the engine air
cleaner/filter:
1. Remove the six screws that secure the cover on.
2. Lift off the cover. 3. Inspect or replace the engine air
cleaner/filter.
4. Align the filter correctly.
5. Install the cover by lowering it over the filter and secure with
the screws.
{WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
