8-6 Climate Controls
Rear Climate Control Panel
A. Fan Control
B. Air Delivery Mode Control
C. 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: 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.

(B) Tire Width:The three‐digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(C) 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 C 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.
(D) 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. (E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Load Range
:Load Range.
(G) 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
steering, power brakes, 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 that is located between
the plies and the tread. Cords
may be made from steel or other
reinforcing materials.

Notice:Your vehicle uses the
unpainted radio antenna bracket
as a remote negative (−) terminal.
Move the antenna coax 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
your vehicle. The repairs would
not be covered by the 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. Notice:
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other or
other metal.
Jumper Cable Removal
A. Unpainted Metal Part or Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and Remote
Negative (−) Terminals
C. Dead Battery or Remote Positive (+) Terminal
