NOTICE  
The future performance and reliabil-  
ity of the engine depends on the care  
and restraint exercised during its  
early life. It is especially important to  
observe the following precautions  
during the first 960 km (600 miles) of  
vehicle operation.  
• After starting, do not race the  
engine. Warm it up gradually.  
• Avoid prolonged vehicle operation  
at a constant speed. Moving parts  
will break in better if you vary your  
speed.  
• Start off from a stop slowly. Avoid  
full throttle starts.  
• Avoid hard braking, especially  
during the first 320 km (200 miles)  
of driving.  
• Do not drive slowly with the trans-  
axle in a high gear.  
• Drive the vehicle at moderate  
engine speeds.

WARNING  
• Fasten your seat belts at all times.  
Even though air bags are equipped  
at the front seating positions, the  
driver and all passengers should  
be properly restrained at all times,  
using the seat belts provided. Refer  
to “Seat belts and child restraint  
systems” section for instructions  
on proper use of the seat belts.  
• Never drive under the influence of  
alcohol or other drugs. Alcohol and  
drugs can seriously impair your  
ability to drive safely, greatly  
increasing the risk of injury to  
yourself and others. You should  
also avoid driving when you are  
tired, sick, irritated or under stress.

The purpose of the catalytic converter is to  
minimize the amount of harmful pollutants  
in your vehicle’s exhaust. Use of leaded  
fuel in vehicles equipped with catalytic  
converters is prohibited, because lead  
deactivates the pollutant-reducing compo-  
nents of the catalyst system.  
The converter is designed to last the life of  
the vehicle under normal usage and when  
unleaded fuel is used. No special mainte-  
nance is required on the converter. How-  
ever, it is very important to keep the engine  
properly tuned. Engine misfiring, which can  
result from an improperly tuned engine,  
may cause overheating of the catalytic  
converter. This may result in permanent

heat damage to the catalytic converter and  
other vehicle components.  
Improving fuel economy  
The following instructions will help you  
improve fuel economy.  
NOTICE  
To minimize the possibility of cata-  
lytic converter or other vehicle dam-  
age:  
• Maintain the engine in the proper  
operating condition.  
• In the event of an engine malfunc-  
tion, particularly one involving  
engine misfire or other apparent  
loss of performance, have the vehi-  
cle serviced promptly.  
• Do not turn off the engine or inter-  
rupt the ignition when the transaxle  
is in gear and the vehicle is in  
motion.  
• Do not try to start the engine by  
pushing or towing the vehicle, or  
coasting down a hill.  
• Do not idle the engine with any  
spark plug wires disconnected or  
removed, such as during diagnos-  
tic testing.  
• Do not idle the vehicle for pro-  
longed periods if idling seems  
rough or there are other malfunc-  
tions.  
Avoid excessive idling  
If you park your vehicle for more than one  
minute, stop the engine and start it again  
later. When warming up a cold engine, do  
not allow the engine to idle or apply full  
throttle until the engine has reached oper-  
ating temperature. Allow the engine to  
warm up by driving.  
54G584S  
Avoid fast starts  
Fast starts away from lights or stop signs  
will consume fuel unnecessarily and  
shorten engine life. Start off slowly.  
WARNING  
Be careful where you park and drive;  
the catalytic converter and other  
exhaust components can get very  
hot. As with any vehicle, do not park  
or operate this vehicle in areas where  
combustible materials such as dry  
grass or leaves can come in contact  
with a hot exhaust system.  
Avoid unnecessary stops  
Avoid unnecessary deceleration and stop-  
ping. Try to maintain a moderate, steady  
speed whenever possible. Slowing down  
and then accelerating again uses more  
fuel.  
Keep a steady cruising speed  
Drive at a constant speed that road and  
traffic conditions will permit.  
• Do not allow the fuel tank to get  
near the empty level.
