For your safety, make sure you have
a clear view through all the windows
befo re driving.
When the indicator in the button is
on, the front passenger’s and rear
passenger compartment
temperatures cannot be set
separately from the driver’s.
Airflow
is divided between
the floor and corner vents and the
defroster vents at the base of the
windshield.
This button directs the main airflow
to the windshield for faster
defrosting. It also overrides any
mode selection you may have made.
When you select , the system
au tomatically switches to fresh air
mode and turns on the A/C. For
faster defrosting, manually set the
fanspeed tohigh.You canalso
increase airflow to the windshield by
closing the corner vents on the
dashboard. To close the vents, rotate
the wheel under each corner vent.
When you turn off by
pressing the button again, the
system returns to its former settings.
This button turns the rear window
def ogger of f and on (see page ).
Pushing this button also turns the
power mirror heaters on and of f .
Use the mode control button to
select the vents the air flows from.

When the indicator in this button is
off, the temperature of the rear
passenger compartment is
synchronized to the driver’s side set
temperature. If the AUTO mode is
selected on the f ront control panel,
you will see the AUTO SYNC on the
rear system display. When the
indicator in this button is on, the
temperature of the rear passenger
compartment can be adjusted withthe rear temperature control buttons.
A passenger can also adjust the fan
speed and airf low.
You can use the rear control panel
when the indicator in the REAR
button on the f ront control panel is
on. Pressing any control button on
the rear control panel turns on the
rear button indicator on the f ront
control panel.

temperature. You will see the AUTO
SYNC on the system display of the
rear control panel.
To set the temperature of the rear
passenger compartment to a
dif f erent value then the driver’s side,
press the REAR button, then press
either temperature control buttons
on the back of the center console.
The word ‘‘SYNC’’ in the display
goes out. You can also adjust the
rear temperature without pressing

To 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 liquid or spray
chemical cleaners on the sensors. Sunlight and T emperature

If your seat belts get dirty, use a sof t
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 bef ore
you use the vehicle.
Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.
This f ilter removes the dust and
pollenthatisbroughtinfromthe
outside through the climate control
system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message in the multi-
inf ormation 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 f low f rom
theclimatecontrolsystembecomes
less than usual.

Are you using the proper starting
procedure? Refer to
on page .
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 page ).
Ifyoufindnothingwrong,youwill
need a qualified technician to find
the problem. See
on page . Although this seems like a simple
procedure, you should take several
precautions.
You cannot start your vehicle by
pushing or pulling it.
Put the transmission in neutral or
Park, and set the parking brake. Turn of f all the electrical acces-
sories: heater, A/C, climate
control, audio system, lights, etc. 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 f rozen, do not try
jump starting until it thaws.

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.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

If the temperatu re gauge stays at
the red mark, turn off the engine.
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
on page ). Start
the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). 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.
Put the radiator cap back on
tightl y. Run the engine, and check
the temperatu re gauge. If it goes
back to the red mark, the engine
needs repair (see on page ).
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.
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
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 tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.

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.

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example: The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices, and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades. Unif orm T ire Quality Grading
