Maintenance
Safety When Performing MaintenanceSome of the most important safety precautions are given here.
However, we cannot warn you of every conc eivable hazard that can arise in 
performing maintenance. Only you can decide whether or not you should perform 
a given task.
• To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames 
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them causing a fire.
• To clean parts, use a commercially available degreaser 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.
u Only operate the engine if there is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on level ground, the parking brake is set, and 
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before 
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instructed, and keep your hands and limbs away 
from moving parts.
• Do not touch the IMA battery and wiring (orange).■
