tion system and irregular engine operation. If
the indicator light is illuminated, contact an
authorized dealer as soon as possible to
bleed the system. If the above indications
come on immediately after refuelling, water
has probably been poured into the tank:
switch the engine off immediately and con -

Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle must
be serviced before any emissions tests can
be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an acci-
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

IF ENGINE FAILS TO START
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme Cold
Weather” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and
hold it there. Crank the engine for no more than
15 seconds. This should clear any excess fuel in
case the engine is flooded. Leave the ignition in
the RUN position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically and
will decrease as the engine warms up.

Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
Damage to the fuel system or emission
control system could result from using an
improper fuel filler cap. A poorly fitting cap
could let impurities into the fuel system.
Also, a poorly fitting aftermarket cap can
cause the “Malfunction Indicator Light

WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable under
certain conditions and be hazardous or explo -
