Rear Climate Control System
The vehicle has a rear climate control system. The
base model includes air outlets in the rear of the center
console for cooling and under-seat air outlets for
heating. The temperature, amount of airflow, and the
air delivery mode is controlled automatically by the front
climate control system.
Some vehicles may have an optional climate control
panel for the rear passenger, located on the back of the
center console.

B. Air Delivery Mode ControlC. Heated Seat
D. Heated Seat
Indicator
9(Off) : Turns off the airflow to the rear seat
passengers. With the air delivery off there may be an
increase in the air rush sound of the front system.
Temperature Control: Turn clockwise or
counterclockwise to increase or decrease the
temperature.
Air Delivery Mode Control: Turn to change the
direction of the airflow for the rear seat passengers.
To change the current mode, select one of the following:
Y (Vent): Air is directed to the console outlets.
\ (Bi-Level): Air is directed to the console and the
floor outlets.
[ (Floor): Air is directed to the floor outlets.
The front climate control system automatically controls
the amount of airflow to the rear seat passengers,
regardless of optional equipment. Airflow to the rear
system turns off when defrost is selected on the front
climate control panel, in order to direct air to clear the
windshield.
z(Heated Seat): Press to turn on rear heated seats.
There are two buttons, each with three indicator lights,
located between the climate control knobs on the rear
climate control panel.
Keep the area under the front seats clear of any objects
so the air in the vehicle can circulate effectively.

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air filter. There are two types of filters
available. There is a standard dust filter that traps small
particles including pollen. There is, also, a dust/odor
filter available that traps dust and pollen and uses a
charcoal element to help reduce many offensive odors
from entering your vehicle. The filter will need to be
changed periodically. For information on when to
change the passenger compartment air filter, see
Scheduled Maintenance on page 7‑3.
Notice:Driving without a passenger compartment
air filter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
filter with a new one.
The access panel for the passenger compartment air
filter is located under the hood near the windshield,
on the passenger side of the vehicle. See Engine
Compartment Overview
on page 6‑13for more
information on location. See Doing Your Own Service
Work
on page 6‑5for information on doing your own
service work.
To access the passenger compartment air filter:
1. Pull back the rubber hood seal from the edge of the leaf screen vent cover.
2. Remove the three fasteners that hold the filter cover in place and slide the cover off.
3. To access the filter, remove the water deflector by lifting the outboard edge of the deflector to release
the retention tab.

BATTERY NOT CHARGING SERVICE
CHARGING SYS (System)
This symbol appears
with this message.
This message displays when a problem with the
charging system has been detected. Have your vehicle
serviced by your dealer.
BATTERY SAVER ACTIVE
This message displays when the system detects that
the battery voltage is dropping beyond a reasonable
level. The battery saver system starts reducing certain
features of the vehicle that may be noticeable. At the
point that the features are disabled, this message is
displayed. It means that the vehicle is trying to save the
charge in the battery.
Turn off all unnecessary accessories to allow the
battery to recharge.
The normal battery voltage range is 11.5 to 15.5 volts.
To monitor battery voltage on the DIC, press the
information button until BATTERY VOLTS displays.
BATTERY VOLTAGE HIGH
This symbol appears
with this message.
This message displays when the electrical charging
system is overcharging the battery. When the system
detects that the battery voltage is above an estimated
16 volts, this message displays.
To reduce the charging overload, use the vehicle's
accessories:
.Turn on the exterior lamps and radio.
.Set the climate control on AUTO and the fan speed
on the highest setting.
.Turn the rear window defogger on.
The normal battery voltage range is 11.5 to 15.5 volts
when the engine is running. To monitor battery voltage
on the DIC, press the information button until BATTERY
VOLTS displays.

Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Service
on page 8‑8. To get help
and keep everyone in the vehicle safe:
.Turn on the Hazard Warning Flasherson
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.
(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 3‑36.
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.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The 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.All Passenger Car Tires Must Conform to Federal
Safety Requirements In Addition To These
Grades.
Treadwear
The 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 (1½) 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, C
The 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.
