IN CASE OF EMERGENCY

204

4. Disconnect the positive (+) end of thejumper cable from the positive (+) post of
the vehicle with the discharged battery.
If frequent jump starting is required to start
your vehicle, you should have the battery and
charging system inspected at an authorized
dealer.
Bump Starting
Never jump start the engine by pushing,
towing or coasting downhill.

NOTE:

You cannot start a vehicle with an automatic
transmission by pushing it.
ENGINE OVERHEATING
If your vehicle is overheating, it will need to be
serviced at an authorized dealer.
Engine overheating may occur in situations
such as (but not limited to) extreme environ -
mental temperatures or frequent engine
stops/starts. If the engine becomes over -heated, the Engine Temperature Warning
Light in the instrument cluster will illuminate
along with a dedicated message
Ú

page 79.
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.
NOTE:

If the cooling fan does not operate while the
engine is running, the engine temperature
will increase. Stop the engine and contact
an authorized dealer.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be seri
-
ously damaged unless repairs are made.
Contact an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s
battery, even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in long
enough without engine operation, the
vehicle’s battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
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.

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 use the vehicle if irregular idling or
operating conditions are experienced.
Cooling System
Coolant Check
Your vehicle has two cooling systems and both
need to be checked to ensure they are at
proper fill levels
Ú
page 214.
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 for any
build-up of insects, leaves or other debris.
Should it be dirty, clean 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.

NOTE:

Before removing the coolant reservoir cap,
wait for the system to cool down.
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.
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 pres
-
sure 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 automat -
ically 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. 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 over -
heated engine. Heat causes pressure to
build up in the cooling system. To prevent
scalding or injury, do not remove the pres -
sure 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.

Topping Up / Draining / Flushing The Engine/
Intercooler Coolant
If the engine coolant (antifreeze) is dirty, have
cleaning and flushing carried out at an autho
-
rized dealer.
For the correct servicing intervals

Ú
page 209.

NOTE:

For topping off, and proper coolant specifi -
cations
Ú
page 263.
Do not use pure water, alcohol-based cool -
ants, 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. Disposal of Used Coolant
Disposal of engine/intercooler coolant is
subject to legal requirements. Contact the
appropriate body to determine local regula
-
tions.

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 the
front of the hood. This is a normal phenom -
enon 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 compo -
nents; for this operation, contact an autho -
rized dealer.

For the correct servicing intervals

Ú page 209.
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 reser-
voir (in the engine compartment)
completely closed.
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.
WARNING! (Continued)
WARNING!
Use only manufacturer's recommended
brake fluid
Ú
page 263. 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.
