GETTING TO KNOW YOUR VEHICLE

Tachometer
The Tachometer indicates the engine
Revolutions Per Minute (RPM).
Adjusting Instrument Panel Lighting
(Brightness Sensor)
Inside the Tachometer there is a light
sensor capable of detecting light and
adjusting the brightness of the
instrument panel and the Connect
system display.
Engine Oil Temperature
Gauge
The digital indicator monitors the
temperature of the engine oil and starts
supplying indications when the oil
temperature reaches approximately
122° F (50°C).Under normal usage, the temperature
should remain around the middle of the
digital scale according to the working
conditions.
The
warning light will turn on to
signal the excessive increase of the
engine oil temperature.
In the event of excessive engine oil
temperature, stop the engine
immediately and contact an authorized
dealer.
Fuel Level Gauge
The digital fuel gauge monitors the
amount of fuel in the tank.
When the
warning light turns on, a
message is displayed, and a chime is
sound when 2.38 Gallons (9.0 L) of fuel
are left in the tank. Note:
If the low fuel warning light turns
on, refuel the vehicle at your nearest
fuel station.
Caution!
Do not travel with the fuel tank almost
empty: any gaps in fuel supply could
damage the catalytic converter.
Speedometer
The speedometer shows the vehicle
speed in miles per hour and/or
kilometers per hour (mph/km/h).

Warning LightWhat It Means What To Do
REAR FOG LIGHT
The warning light switches on when the rear fog light is
activated.
OBD / INJECTION SYSTEM FAILURE
In normal conditions, when the ignition is cycled to ON,
the warning light switches on, but it should switch off as
soon as the engine is started.
The operation of the warning light may be checked by the
traffic police using specific devices. Comply with the laws
and regulations of the country where you are driving.
Injection System Failure
If the warning light remains on, or it switches on while
driving, the injection system is not working properly. The
warning light on constantly signals a malfunction in the
supply/ignition system which could cause high exhaust
emissions, a possible loss of performance, poor
driveability and high consumption.
The warning light switches off if the malfunction
disappears, but is still stored by the system.Under these conditions, the vehicle can continue
travelling at moderate speed but without demanding
excessive effort from the engine or high speed.
Prolonged use of the car with the warning light on
constantly may cause damage. Contact an authorized
dealer as soon as possible.
Catalytic Converter Damaged
If the warning light flashes, it means that the catalytic
converter may be damaged. Release the accelerator pedal to lower the speed of the
engine until the warning light stops flashing. Continue at
moderate speed, trying to avoid driving conditions that
may cause further flashing and contact an authorized
dealer as soon as possible.

STARTING AND OPERATING

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!
Turn vehicle off and disconnect the fan
motor lead before working near the radiator
cooling fan.
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.
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 is hot.
Engine Coolant Check
Check the engine 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 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

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
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
malfunctioning and may require immediate
service. Contact your 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.
Note:
Intentional tampering with the
emissions control system can result in
civil penalties being assessed against
you.
