EXPLANATION OF MAINTENANCE ITEMS
T
he following descriptions are
provided to give you a better
understanding of the maintenance
items that should be performed on your
vehicle. The scheduled maintenance log
indicates at which mileage/time intervals
each item should be performed. Please
note that many maintenance items should
be performed only by a qualified technician.
For further information on maintenance
items you can perform yourself, see the
“Maintenance and Care” section of the
Owner’s Manual.
Automatic Transmission Fluid
Inspect or replace at specified intervals.
When performing inspections, check each
component for signs of leakage. If you
discover any leakage, have it repaired by
a qualified technician immediately.
Ball Joints and Dust Covers
Check the suspension and steering
linkage ball joints for looseness and
damage. Check all dust covers for
deterioration and damage. Replace
any deteriorated or damaged parts.
A qualified technician should perform
these operations.
Brake Lines and Hoses
Visually inspect for proper installation.
Check for chafing, cracks, deterioration
and signs of leakage. Replace any
deteriorated or damaged parts. A qualified
technician should perform these operations.
Brake Linings/Drums and
Brake Pads/Discs
Check the brake linings (shoes) and
drums for scoring, burning, fluid leakage,
broken parts and excessive wear. Check
the pads for excessive wear and the discs
for runout, excessive wear and fluid
leakage. Replace any deteriorated or
damaged parts. A qualified technician
should perform these operations.
Cabin Air Filter
Replace at specified intervals. Driving in
heavy traffic, on dirt roads or in urban,
desert or dusty areas may shorten filter’s
life. More frequent replacement may
be necessary.
Drive Belts
Inspect for cracks, excessive wear and
oiliness. Check the belt tension and adjust
if necessary. Replace the belts if they
are damaged.
