indicator off, the temperature of the
rear passenger compartment is
synchronized to the driver's side set
temperature. You will see the AUTO
SYNC on the system display of the

temperature if you set the
temperature control below the
outside temperature.Recirculation ButtonWhen the indicator in the button is
on, air from the vehicle's interior is
sent throughout the system again.
When the indicator is off, air is
brought in from the outside of the
vehicle (fresh air mode).
The outside air intakes for the
climate control system are at the
base of the windshield. Keep this
area clear of leaves and other debris.
The system should be left in fresh air
mode under almost all conditions.
Keeping the system in recirculation
mode, particularly with the A/C off,
can cause the windows to fog up.

Sunlight and Temperature
SensorsTo regulate the interior temperature
and humidity, the climate control
system has two sensors. A sunlight
sensor is located in the top of the
dashboard and a temperature/
humidity sensor is next to the
steering column. Do not cover the
sensors or spill any liquid on them.

Dust and Pollen Filter
This filter removes the dust and
pollen that is brought in from the
outside through the climate control
system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message on the multi-
information display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the flow from
the climate control system becomes
less than usual.Cleaning the Seat Belts
If your seat belts get dirty, use a soft
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air-dry before
you use the vehicle.Dirt build-up around the openings of
the seat belt anchors can cause the
belts to retract slowly. Wipe the
openings with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.

●Are you using the proper starting
procedure? Refer toStarting the
Engine on page339.●Do you have fuel? Check the fuel
gauge; the warning indicator may
not be working.●There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses (see
page440).
If you find nothing wrong, you will
need a qualified technician to find the
problem. See Emergency Towing on
page446. Jump Starting
Although this seems like a simple
procedure, you should take several
precautions.
A battery can explode if you do
not follow the correct
procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
You cannot start your vehicle by
pushing or pulling it.
To Jump Start Your Vehicle:1. Open the hood, and check the physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.If a battery sits in extreme cold, the
electrolyte inside can freeze. Attempting
to jump start with a frozen battery can
cause it to rupture.
2. Turn off all the electricalaccessories: heater, A/C, climate
control, audio system, lights, etc.
Put the transmission in neutral or
Park, and set the parking brake.

4. If the temperature gauge stays atthe red mark, turn off the engine.
5. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page446).
6. If you do not find an obvious leak, check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the
temperature gauge, or lower,
before checking the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off. 9. Start the engine and set the
climate control to AUTO at ‘‘Hi. ’’
Add coolant to the radiator up to
the base of the filler neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see Emergency
Towing on page446).
11. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.
