8-6 Climate Controls
Rear Climate Control Panel
1. Fan Control
2. Air Delivery Mode Control
3. Temperature Control
For vehicles with a rear climate
control panel, it is located overhead
behind the driver and front
passenger, centered in front of the
second row. To adjust the rear
climate control panel settings by a
rear seat passenger, the front
climate control panel fan knob must be in the AUX position. The fan
speed, air delivery mode, and
temperature can then be adjusted.
AUX (Auxiliary):
Turn the fan knob
on the front climate control panel to
AUX to let rear seat passengers use
the control panel in the rear seating
area. This disables the front control
panel. To return control to the front
panel, move the fan knob out
of AUX.
9(Off): Turns the system off.
9(Fan Control): Turn clockwise
or counterclockwise to increase or
decrease the fan speed in the rear
seating area.
Temperature Control: Turn
clockwise or counterclockwise to
increase or decrease the
temperature in the rear
seating area.
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 remains at cabin
temperature.
Air Delivery Mode Control: Turn
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): Air is directed to the
upper outlets, with some directed to
the floor outlets.

(3) Aspect Ratio:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item 3 of the light truck
(LT-Metric) tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter
:Diameter of
the wheel in inches.
(6) Load Range
:Load Range. (7) Service Description
:The
service description indicates the
load index and speed rating of a
tire. If two numbers are given as
in the example, 120/116, then
this represents the load index for
single versus dual wheel usage
(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load. This
does not apply to Goodyear
LT225/75R16 G949 RSA and
Goodyear LT225/75R16 G933
RSD commercial truck tires; see
the dual tire and single tire
maximum load and load range
letter designations on the tire
sidewall.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.
Belt
:A rubber coated layer of
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.

it to the positive (+) terminal of
the good battery. Use a remote
positive (+) terminal if the vehicle
has one.
7. Now connect the black negative (−) cable to the
negative (−) terminal of the good
battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative (−) terminal
on the vehicle with the dead
battery. On your van, use the
unpainted radio antenna bracket
as a remote negative (−)
terminal.
8. Connect the other end of the
negative (−) cable to the
negative (−) terminal location on
the vehicle with the dead battery.
On your van, use the unpainted
radio antenna bracket as a
remote negative (−) terminal.
{Caution
The vehicle uses the unpainted
radio antenna bracket as a
remote negative (-) terminal.
Move the antenna coaxial cable
out of the way before clamping
the negative jumper cable to the
fixed antenna bracket. Avoid
touching the negative cable clamp
to the air conditioning line. Failure
to do either of these could
damage the vehicle. The repairs
would not be covered by the
vehicle warranty.
9. Now start the vehicle with the good battery and run the engine
for a while.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.
