Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as once a month or before a long
trip. The best time to check the engine oil level is approxi-
mately five minutes after a fully warmed engine is shut off.
Do not check oil level before starting the engine after it has
sat overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground, and
approximately five minutes after a fully warmed engine is
shut off, will improve the accuracy of the oil level readings.
Maintain the oil level between the range markings on the
dipstick. The safe range is indicated by a crosshatch zone.
Adding 1 quart (0.9 Liters) of oil when the reading is at the
low end of the indicated range will result in the oil level at
the full end of the indicator range.

Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.

WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.

vals exceed 10,000 miles (16,000 km), twelve months or

350 hours of engine run or idle time is generally only a
concern for fleet customers.
