ENGINE OVERHEATING
Engine overheating may occur in
situations of extreme environmental
temperatures, frequent engine
stops/starts, or driving in heavy traffic.
If the engine becomes overheated, the
Engine Temperature Warning Light in the
instrument cluster will illuminate along
with a dedicated message. Refer to
"Warning Lights And Messages" in the
"Getting To Know Your Instrument Panel"
for more information.
In any of the following situations, you can
reduce the potential for overheating by
taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place
the transmission in NEUTRAL, but do not
increase engine idle speed.
Note: There are steps that you can take
to slow down an impending overheat
condition:
If your air conditioner (A/C) is on, turn
it off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
You can also turn the temperature
control to maximum heat, the mode
control to floor and the blower control to
high. This allows the heater core to act
as a supplement to the radiator and aids
in removing heat from the engine cooling
system.
Warning!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open the
hood until the radiator has had time to cool.
Never try to open a cooling system pressure
cap when the radiator or coolant bottle is
hot.
Caution!
Driving with a hot cooling system could
damage your vehicle. If temperature gauge
reads “H”, pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned
off until the pointer drops back into the
normal range. If the pointer remains on the
“H”, turn the engine off immediately, and call
for service.
If Steam Is Coming From The Engine
Compartment
Do not go near the front of the vehicle.
Stop the engine. Wait until the steam
dissipates. Then, open the hood and start
the engine.
If Neither Coolant Nor Steam Is
Escaping
Open the hood and idle the engine until it
cools.
Note:
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and contact your authorized
dealer.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Contact your authorized dealer.

Then, check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
Exhaust System
Adequate maintenance of the engine
exhaust system represents the best
protection against leaks of carbon
monoxide into the passenger
compartment.
If an unusual noise from the exhaust or
the presence of smoke in the passenger
compartment is identified, or if the
underbody or rear section of the vehicle
have been damaged, have the entire
exhaust system and adjoining bodywork
areas checked at your authorized dealer
to identify any components which are
broken, damaged, worn or have moved
from their correct fitting position.Open welding or loose connections may
permit exhaust gas to enter the
passenger compartment.
Have the exhaust system checked every
time the vehicle is raised. Replace the
components where necessary (for these
operations, contact an authorized
dealer).
In normal operating conditions, the
catalytic converter does not require
maintenance. To ensure that it operates
correctly, however, and prevent it from
getting damaged, it is extremely
important that the engine operates
perfectly.
To minimize the risk of damaging the
catalytic converter, proceed as follows:
Do not stop the engine or deactivate
the ignition with gear engaged and
vehicle in motion.
Do not attempt to start the engine by
bump starting.
Do not persist in using the vehicle if
idling is very irregular or the operating
conditions are very notably irregular.
Warning!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you.
A hot exhaust system can start a fire if
you park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system.
Do not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Cooling System
Warning!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open the
hood until the radiator has had time to cool.
Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when the
hood is raised. The fan starts automatically
and may start at any time, whether the
engine is running or not.
When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.

Coolant Check
Your vehicle has two cooling systems and
they both need to be checked to ensure
they are at proper fill levels. Refer to the
“Engine Compartment” section for the
locations.
Check the engine coolant and intercooler
coolant level every oil change or before
long trips.
If there are impurities in the engine
coolant, the system must be drained,
flushed and refilled: contact an
authorized dealer.
Check the front part of the condenser to
check for any build-up of insects, leaves
or other debris. Should it be dirty, clean it
by spraying delicately with water.
Check the hoses of the engine/
intercooler cooling system to ensure that
the rubber has not deteriorated and that
there are no cracks, tears, cuts or
obstructions in the expansion tank side
and radiator side connectors. Should
there be any doubt regarding leaks from
the system (e.g. if frequent top ups are
required), have the seal checked at an
authorized dealer.
With the engine off and at normal
operating temperature, check that the
cooling system radiator cap is closed
properly.
Warning!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated
engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or
injury, do not remove the pressure cap while
the system is hot or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Note: Before removing the coolant
reservoir cap, wait for the system to cool
down.
Topping Up / Draining / Flushing The
Engine/Intercooler Coolant
If the engine coolant (antifreeze) is dirty,
have cleaning and flushing carried out at
an authorized dealer.
See the "Maintenance Plan" for the
correct servicing intervals.
Note:
For topping up, use a fluid with the
same characteristics as those indicated
in the "Fluids And Lubricants" table (see
"Technical Specifications" chapter).
Do not use pure water, alcohol-based
coolants, corrosions inhibitors or
additional anti-rust products because they may be incompatible with the
engine coolant and cause the clogging of
the radiator. The use of propylene
glycol-based coolant is also not
recommended.
Engine Cooling/Intercooler System Cap
To prevent loss of engine coolant, make
sure that the expansion tank cap is
closed. If it is open, screw it completely
until you reach/hear the click.
Periodically check the cap and clean it
from any foreign bodies that may have
deposited on the external surface.
Warning!
Never add coolant with the engine hot or
overheated.
Do not attempt to cool an overheated
engine by loosening or removing the cap.
The heat causes a considerable increase in
pressure in the cooling system.
To prevent damage to the engine, only use
the engine cooling circuit caps provided.
Disposal Of Used Coolant
Disposal of engine/intercooler coolant is
subject to legal requirements: contact
the appropriate body to determine local
regulations.

SERVICING AND MAINTENANCE

Note:
To prevent the fluid from being
ingested by children or animals, do not
keep it in open containers or pour it on
the ground. If ingested, contact a doctor
immediately. Eliminate any traces of
fluid from the ground immediately.
When the vehicle stops after a short
trip, steam may be seen coming out from
front of the hood. This is a normal
phenomenon which is due to the
presence of rain, snow or a lot of
moisture on the surface of the radiator.
With engine and system cold, do not
top up with coolant beyond the
maximum level indicated on the
reservoir in the engine compartment.
Braking System
In order to guarantee the efficiency of
the braking system, periodically check its
components; for this operation, contact
an authorized dealer.
See the "Maintenance Plan" for the
correct servicing intervals.
Note: Driving with your foot resting on
the brake pedal may compromise its
efficiency, increasing the risk of
accidents. When driving, never keep your
foot on the brake pedal and don’t put
unnecessary strain on it to prevent the brakes from overheating: excess pad
wear may cause damage to the braking
system.
When an insufficient oil level is
detected, contact an authorized dealer
to have the system checked.
Always keep the cap of the brake
fluid reservoir (in the engine
compartment) completely closed.
Warning!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information. Using the wrong type of brake
fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder
reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake fluid
or fluid that has been in a tightly closed
container. Keep the master cylinder
reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly
during hard or prolonged braking, resulting
in sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to avoid
its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
Automatic Transmission
Use only a transmission oil with the same
characteristics as those indicated in the
"Fluids and Lubricants" table (see
"Technical Specifications" chapter).
Special Additives
Do not use any type of additive with the
automatic transmission oil. The
automatic transmission oil is a product
designed specially for this vehicle and its
performance may be compromised
through the use of further additives.
Caution!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such
damage is not covered by the New Vehicle
Limited Warranty.
