Safety When Performing Maintenance
Some of the most important safe ty 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 and a ll High Voltage system related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the motor or the surrounding parts 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.
• The vehicle must be in a stationary condition.
u Make 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.
u Make sure to let the power system cool thoroughly before touching vehicle
parts.
• Be aware that moving parts can injure you.
u Do not activate the power system unless instructed to do so.
Keep your hands and limbs away from moving parts.

*1: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and
from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles.
*2: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. This requires transmission fluid changes more frequently than recommended by the Maintenance
Minder. If you regularly drive your vehicle under these conditions, have the transmission fluid changed
every 31,250 miles.
*3: If a Maintenance Minder message does not appear more than 3 years after the display for item 7 is reset, change the brake fluid and replace air cleaner element every 3 years.
