2006 GMC SAVANA climate control

Rear Heating System
Your vehicle may have a rear heating system that
allows you to adjust the amount of air flowing into the
rear of the vehicle, from the front-seating area. This
feature works with the main climate-control system in
your vehicle.
REAR HEAT:The thumbwheel for this system is
located to the left of the audio system.
9(Fan):Turn the thumbwheel up or down to increase
or decrease the amount of heated air sent to the
rear-seating area.HI:Turn the thumbwheel to this position to supply
the most amount of heat to the rear-seating area.
LO:Turn the thumbwheel to this position to supply
the least amount of heat to the rear-seating area.
OFF:Turn the thumbwheel to this position to turn
the rear heating system off.
Rear Air Conditioning and Heating
System
Your vehicle may have a rear heating and
air-conditioning system. This system regulates the
temperature, the fan speed and the air delivery for the
rear-seat passengers only. It also works with the
main climate-control system in your vehicle.
Front Climate Control Panel
3-21

Use this control panel when you would like to maintain
a separate temperature setting. Adjust the direction
of the airflow or adjust the fan speed for the rear seat
passenger(s).
If your vehicle has a 135 inch (343 cm) wheelbase, a
rear control panel for this system is located in the
second row behind the driver in the rear of your vehicle.
A rear seat passenger can use this control panel to
personally adjust the temperature, the direction of the
airflow and the fan speed for the rear seating area.
The fan knob located on the front climate control panel
must be turned to REAR CNTL to allow a rear seat
passenger to use the control panel in the rear seating
area. Performing this action disables the front control
panel. To return control to this panel, move the fan knob
out of REAR CNTL.
Turn the center knob clockwise or counterclockwise
to change the direction of the airflow in the rear
seating area.To change the current mode, select one of the following:
H(Vent):Use this mode to direct air to the upper
outlets, with a little air directed to the floor outlets.
2(Floor):Use this mode to direct most of the air to
the floor outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to HIGH, MED (Medium) or LOW to
increase or decrease the fan speed in the rear-seating
area. Turn the knob to OFF to turn off the fan.
Temperature Control:To increase or decrease the
temperature for the rear of the vehicle, turn the
right knob located on the climate-control panel.
The air-conditioning system on the main climate control
panel must be turned on to direct cooled air to the
rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin
temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.

system, seeClimate Control System on page 3-17.

Driving with a Trailer
{CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide (CO) could come into your vehicle.
You can not see or smell CO. It can cause
unconsciousness or death. SeeEngine
Exhaust on page 2-26. To maximize your safety
when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum air
because it only recirculates the air inside
your vehicle. See Climate Control System
in the Index.Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.

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 (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, 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. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
