Part B: Owner Checks and Services

These owner checks and services should be performed
at the intervals specified to help ensure vehicle safety,
dependability, and emission control performance.
For your safety and that of others, any of the
safety-related components that may have been
damaged in an accident should be checked and any
needed repairs made before operating the vehicle.
At the minimum, these routine checks should be made
every 6 months or 10 000 km (6,000 miles), whichever
occurs first. Whenever repairs are needed, have them
completed before operating the vehicle.
Air brake system reservoirs should be drained daily and
any electric air compressor should be drained weekly.
See Brakes on page 5 33.
