be performed only by a qualied 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 specied intervals.
When performing inspections, check each
component for signs of leakage. If you
discover any leakage, have it repaired by
a qualied 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 qualied technician should perform
these operations.
Brake Lines and Hoses
Visually inspect for proper installation.
Check for chang, cracks, deterioration
and signs of leakage. Replace any
deteriorated or damaged parts. A qualied
technician should perform these operations.
Brake Linings/Drums and
Brake Pads/Discs
Check the brake linings (shoes) and
drums for scoring, burning, uid leakage,
broken parts and excessive wear. Check
the pads for excessive wear and the discs
for runout, excessive wear and uid
leakage. Replace any deteriorated or
damaged parts. A qualied technician
should perform these operations.
Cabin Air Filter
Replace at specied intervals. Driving in
heavy trafc, on dirt roads or in urban,
desert or dusty areas may shorten lter’s
life. More frequent replacement may
be necessary.
