Additional Electric Heater (If Equipped)
The additional electric heater ensures more rapid pas-
senger compartment heating.
It activates in cold weather conditions, if the following
conditions are verified:
•outside temperature low;
• engine coolant temperature low;
• engine on;
• fan speed set to 1st speed;
• Temperature Control knob turned completely clock-
wise to red section.
The heater is switched off when at least one of the
conditions above is no longer verified.
NOTE: The power of the electric heater is modulated
according to the battery voltage.CAUTION!
Failure to follow these cautions can cause damage
to the heating elements:
• Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft
cloth and a mild washing solution, wiping paral-
lel to the heating elements. Labels can be peeled
off after soaking with warm water.
• Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of
the window.
• Keep all objects a safe distance from the window.
System Maintenance
In winter, the climate control system must be turned on
at least once a month for about 10 minutes.
Have the system inspected at an authorized dealership
before the summer.
NOTE: The system uses R-1234yf coolant which does
not pollute the environment in the event of accidental
leakage. Under no circumstances is the use of R-134a
allowed.

NOTE:The system will not automatically sense the
presence of fog, mist or ice on the windshield. DE-
FROST mode must be manually selected to clear the
windshield and side glass.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is func-
tioning properly and the proper amount, type, and
concentration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes, in fresh air
with the blower setting on high. This will ensure ad-
equate system lubrication to minimize the possibility of
compressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower
speed. Do not use the Recirculation mode without A/C
for long periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves.
Leaves collected in the air intake may reduce airflow,
and if they enter the plenum, they could plug the water
drains. In winter months, make sure the air intake is
clear of ice, slush, and snow.
A/C Air Filter
The climate control system filters out dust and pollen
from the air. Contact your authorized dealer to service
your A/C air filter, and to have it replaced when needed.

appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
WARNING!
•The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction af-
forded by prevailing road conditions. ESC cannot
prevent all accidents, including those resulting
from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also can-
not prevent collisions resulting from loss of ve-
hicle control due to inappropriate driver input for
the conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.
• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling

characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that reduces the
effectiveness of the ESC system can increase the
risk of loss of vehicle control, vehicle rollover,
personal injury and death.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come on
when the ignition switch is turned to the
MAR (ACC/ON/RUN) position for four sec-
onds. If the ESC Activation/Malfunction Indicator
Light comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread
depth becomes a 1/16 of an inch (1.6 mm). When the
tread is worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement Tires” in this
section for further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
• Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle
maintenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire fail-
ure. You could lose control and have a collision
resulting in serious injury or death.

CAUTION!(Continued)
•Do not drive for a prolonged period on dry
pavement.
• Observe the traction device manufacturer ’s in-
structions on the method of installation, operat-
ing speed, and conditions for use. Always use the
suggested operating speed of the device manufac-
turer ’s if it is less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare
tire.
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season
type tires. Rotation will increase tread life, help to
maintain mud, snow and wet traction levels, and con-
tribute to a smooth, quiet ride. Refer to the “Maintenance Schedule” for the proper
maintenance intervals. The reasons for any rapid or
unusual wear should be corrected prior to rotation
being performed.
The suggested rotation method is the “forward cross”
shown in the following diagram. This rotation pattern
does not apply to some directional tires that must not be
reversed.

(20°C) and the measured tire pressure is 27 psi (186
kPa), a temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 23 psi (159 kPa). This
tire pressure is sufficiently low enough to turn on the
Tire Pressure Monitoring Telltale Light. Driving the
vehicle may cause the tire pressure to rise to approxi-
mately 27 psi (186 kPa), but the Tire Pressure Monitor-
ing Telltale Light will still be on. In this situation, the
Tire Pressure Monitoring Telltale Light will turn off only
after the tires are inflated to the vehicle’s recommended
cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System (TPMS) sensor to become inoperable.
(Continued)
CAUTION! (Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealership to have your sensor function
checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.

NOTE:Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with
the engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
• Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
ADDING FUEL
1. Open the fuel filler door.
2. There is no fuel filler cap. A flapper door inside the
pipe seals the system.
3. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper door while
refueling.
NOTE: Only the correct size nozzle opens the latches
allowing the flapper door to open.
4. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is full.
5. Remove the fuel nozzle and close the fuel door.
