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 :
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: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: Air is directed to the upper outlets,
with some directed to the floor outlets.
2: 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.
For information on how to use the main
climate control system, see Climate Control
Systems 0119. For information on
ventilation, see Air Vents0123.
Air Vents
Use the outlets located near the center and
on the sides of the instrument panel to

Warning (Continued)
.Read and follow all the instructions on
the fuel pump island.
.Turn off the engine when refueling.
.Keep sparks, flames, and smoking
materials away from fuel.
.Do not leave the fuel pump
unattended.
.Avoid using electronic devices while
refueling.
.Do not re-enter the vehicle while
pumping fuel.
.Keep children away from the fuel
pump and never let children
pump fuel.
.Before touching the fill nozzle, touch a
metallic object to discharge static
electricity from your body.
.Fuel can spray out if the fuel cap is
opened too quickly. This spray can
happen if the tank is nearly full, and is
more likely in hot weather. Open the
fuel cap slowly and wait for any hiss
noise to stop, then unscrew the cap all
the way.
Turn the fuel cap counterclockwise to
remove. When refueling, hang the fuel cap
from the hook on the fuel door. Fully insert
and latch the fill nozzle, begin fueling.
{Warning
Overfilling the fuel tank by more than
three clicks of a standard fill nozzle may
cause:
.Vehicle performance issues, including
engine stalling and damage to the fuel
system.
.Fuel spills.
.Under certain conditions, fuel fires.Be careful not to spill fuel. Wait five seconds
after you have finished pumping before
removing the fill nozzle. Clean fuel from
painted surfaces as soon as possible. See
Exterior Care
0241. Reinstall the cap by
turning it clockwise until it clicks. Push the
fuel door closed.
{Warning
If a fire starts while you are refueling, do
not remove the fill nozzle. Shut off the
flow of fuel by shutting off the pump or
by notifying the station attendant. Leave
the area immediately.
Caution
If a new fuel cap is needed, get the right
type of cap from your dealer. The wrong
type of fuel cap may not fit properly,
may turn on the malfunction indicator
lamp, and could damage the fuel system
and emissions system. See Malfunction
Indicator Lamp (Check Engine Light) 076.

How to Add Coolant to the Recovery
Tank for Gasoline Engines
{Warning
Spilling coolant on hot engine parts can
burn you. Coolant contains ethylene
glycol and it will burn if the engine parts
are hot enough.
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,(Continued)
Warning (Continued)
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
Caution
Failure to follow the specific coolant fill
procedure could cause the engine to
overheat and could cause system
damage. If coolant is not visible in the
surge tank, contact your dealer.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the coolant
recovery tank.
How to Add Coolant to the Radiator
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system, (Continued)
Warning (Continued)
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If coolant is needed, add the proper mixture
directly to the radiator, but be sure the
cooling system is cool before this is done.
1. Remove the radiator pressure cap when the cooling system, including the
radiator pressure cap and upper radiator
hose, is no longer hot. Turn the pressure
cap slowly counterclockwise until it first
stops. Do not press down while turning
the pressure cap.
If a hiss is heard, wait for that to stop.
A hiss means there is still some
pressure left.
2. Keep turning the pressure cap, but now push down as you turn it. Remove the
pressure cap.

badly injured or killed if the vehicle slips
off the jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
Caution
Using a jack to raise the vehicle without
positioning it correctly could damage
your vehicle. When raising your vehicle
on a jack, be sure to position it correctly
under the frame and avoid contact with
the plastic molding.
5. Turn the wheel wrench clockwise to raise the vehicle. Raise the vehicle far enough
off the ground so there is enough room
for the spare tire to fit.
6. Remove all the wheel nuts.
7. Take the flat tire off of the mountingsurface.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
cause wheel nuts to become loose
over time. The wheel could come off
and cause a crash. When changing a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, a cloth
(Continued)
Warning (Continued)
or paper towel can be used; however,
use a scraper or wire brush later to
remove all rust or dirt.
8. Remove any rust or dirt from the wheel bolts, mounting surfaces, and spare
wheel.
{Warning

specification after replacing. Follow the
(Continued)
Warning (Continued)
torque specification supplied by the
aftermarket manufacturer when using
accessory locking wheel nuts. See
Capacities and Specifications0258 for
original equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To
avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper
sequence and to the proper torque
specification. See Capacities and
Specifications 0258 for the wheel nut
torque specification.
11. Use the wheel wrench to tighten the nuts firmly. Turn the wheel wrench
clockwise and in a crisscross sequence, as
shown.
