Driving
Turbo Engine Vehicle
Handling Precautions
The turbocharger is a high-precision device designed to obtain greater horsepower
by delivering a large volume of compressed ai r into the engine using a turbine driven
by the engine’s exhaust gas pressure. • When the engine is cold just afte r starting, avoid hard or sudden
acceleration.
• Always replace the engine oil and en gine oil filter according to the
Maintenance Minder TM
.
The turbine rotates at very high speed s over 100,000 rpm and its temperature
reaches over 1,292°F (700°C). It is lubricated and cooled by engine oil.
If you fail to replace the engine oil and filter at the scheduled distance or interval,
deteriorated engine oil may cause failure such as sticking and abnormal noise of the
turbine bearing.
1Turbo Engine Vehicle
The scheduled maintenance intervals for replacing
the engine oil and filt er is indicated on the
Maintenance Minder TM
. Follow the information of
when to replace them.

Safety When Performing Maintenance
Some of the most important safety precautions are given here. However, we cannot
warn you of every conceivable hazard that can arise in performing maintenance.
Only you can decide whether you should perform a given task. • To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood and hatch.
uHeat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
uOnly operate the engine if th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
uMake sure your vehicle is parked on le vel ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
uMake sure to let the power system, including the engine and exhaust system,
cool thoroughly before touching vehicle parts.
• Be aware that moving parts can injure you.
uDo not activate the power system unle ss instructed, and keep your hands and
limbs away from moving parts. When the power system is on, the engine can
automatically start, or the radiator fa n may start operating without the engine
running.
