The defogger only works when the
ignition is in ON/RUN. The defogger
turns off if the ignition is in the ACC/
ACCESSORY or LOCK/OFF
position.
Do not drive the vehicle until all the
windows are clear.
Caution
Do not use a razor blade or sharp
object to clear the inside rear
window. Do not adhere anything
to the defogger grid lines in the
rear glass. These actions may
damage the rear defogger.
Repairs would not be covered by
the vehicle warranty.
Rear Heating System
If equipped, the rear heating system
lets you 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 the vehicle.
AUX :The thumbwheel for this
system is on the instrument panel
below 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.
Q(High) : This position supplies the
most amount of heat to the rear
seating area.
c(Medium) : This position
supplies half the amount of heat to
the rear seating area.
R(Low) : This position supplies the
least amount of heat to the rear
seating area.
9(Off) : This turns the rear
heating system off.
Rear Climate Control
System
If equipped with a rear heating and
air conditioning system, it controls
the temperature, fan speed, and air
delivery for the rear seat
passengers only. The front climate
control panel is in the overhead
console between the driver and
front passenger.

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.
2(Floor) : Air is directed to the
floor outlets.
Be sure to keep the area under the
front seats clear of any objects so
that the air inside of the vehicle can
circulate effectively.

254 Vehicle Care
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.
Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. See Tire
Pressure 0256.
Curb Weight
:The weight of a
motor vehicle with standard and
optional equipment including the

282 Vehicle Care
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.
Caution
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
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Have the vehicle towed on a flatbed
car carrier or a wheel lift tow truck. If
a wheel lift tow truck is used, the
drive wheels cannot contact the
road while the vehicle is being
towed. A wheel dolly must be used
to lift all drive wheels off the ground.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
