2010 CHEVROLET IMPALA climate control

Compass CalibrationThe compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle
in circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers,
or other industrial structures, if possible.
If CAL should ever appear in the DIC display, the
compass should be calibrated.
If the DIC display does not show a heading, for example,
N for North, or the heading does not change after making
turns, there may be a strong magnetic field interfering
with the compass. Such interference may be caused by a
magnetic CB or cell phone antenna mount, a magnetic
emergency light, magnetic note pad holder, or any other
magnetic item. Turn off the vehicle, move the magnetic
item, then turn on the vehicle and calibrate the compass.To calibrate the compass, use the following procedure:
Compass Calibration Procedure1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is located. See “Compass
Variance (Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the vehicle information button until
PRESS
V
TO CALIBRATE COMPASS displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle in tight circles at less
than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION COMPLETE
for a few seconds when the calibration is complete.
The DIC display will then return to PRESS
V
TO
CALIBRATE COMPASS.

REMOTE KEY LEARNING ACTIVEThis message displays while you are matching a
Remote Keyless Entry (RKE) transmitter to your vehicle.
See “Matching Transmitter(s) to Your Vehicle” under
Remote Keyless Entry (RKE) System Operation
on page 3-4andDIC Operation and Displays on
page 4-37for more information.REPLACE BATTERY IN REMOTE KEYThis message displays when the battery in the Remote
Keyless Entry (RKE) transmitter needs to be replaced.
To replace the battery, see “Battery Replacement” under
Remote Keyless Entry (RKE) System Operation on
page 3-4.RIGHT REAR DOOR OPENThis message displays when the passenger side rear
door is not closed properly. Make sure that the door
is closed completely.SERVICE A/C (Air Conditioning)
SYSTEMThis message displays when the electronic sensors that
control the air conditioning and heating systems are
no longer working. Have the climate control system
serviced by your dealer/retailer if you notice a drop
in heating and air conditioning efficiency.
SERVICE AIR BAGThis message displays when there is a problem with
the airbag system. Have your vehicle serviced by your
dealer/retailer immediately. SeeAirbag Readiness
Light on page 4-24for more information.SERVICE BATTERY CHARGING
SYSTEMThis message displays when there is a problem with the
generator and battery charging systems. Driving with this
problem could drain the battery. Turn off all unnecessary
accessories. Stop and turn off the vehicle as soon as it is
safe to do so. Have the electrical system checked by your
dealer/retailer immediately.SERVICE BRAKE SYSTEMThis message displays when service is required on the
brake system. Have the brake system serviced by
your dealer/retailer as soon as possible. The brake
system warning light also appears on the instrument
panel cluster when this message appears on the DIC.
SeeBrake System Warning Light on page 4-27.

Blizzard ConditionsBeing stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Assistance Program on page 8-7.To
get help and keep everyone in the vehicle safe:•
Turn on theHazard Warning Flashers on page 4-3.
•
Tie a red cloth to an outside mirror.{
WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
•
Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
•
Check again from time to time to be sure
snow does not collect there.
WARNING: (Continued)
WARNING: (Continued)
•
Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
•
Fully open the air outlets on or under the
instrument panel.
•
Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3-31.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine off
and close the window most of the way to save heat.

Uniform Tire Quality GradingQuality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:Treadwear 200 Traction AA
Temperature AThe following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters
of 10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.Traction – AA, A, B, CThe traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
