SERVICING AND MAINTENANCE

212

(Continued)
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 an 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, 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 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 204.
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.
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 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 position. The fan is
temperature controlled and can start at any
time the ignition is in the ON position.
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.

(Continued)
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the respon
-
sibility of the manufacturer and may void or not
be covered under New Vehicle Limited Warranty.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the engine,
emissions, and fuel system components.
Problems that result from running CNG or LP are
not the responsibility of the manufacturer and
may void or not be covered under the New
Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic
additive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system
performance in some vehicles. The manufacturer
recommends that gasoline without MMT be used
in your vehicle. The MMT content of gasoline may
not be indicated on the gasoline pump; therefore,
you should ask your gasoline retailer whether the
gasoline contains MMT. MMT is prohibited in
Federal and California reformulated gasoline.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of TOP TIER Detergent
Gasoline is recommended. Visit

www.toptiergas.com
for a list of TOP TIER
Detergent Gasoline retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials
intended for gum and varnish removal may
contain active solvents or similar ingredients.
These can harm fuel system gasket and
diaphragm materials.
FUEL SYSTEM CAUTIONS
NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being
assessed against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage the
emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the catalytic
converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc-
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle performance
problems resulting from the use of such fuels
or additives is not the responsibility of the
manufacturer and may void or not be
covered under the New Vehicle Limited
Warranty.
