Service and Maintenance
Components requiring lubrication
and fluid check shown in this
manual are typical representations.
Caution
Use of the incorrect fluids and
lubricants may damage the
vehicle and the damages may not
be covered by the vehicle
warranty. Always use the correct
fluids and lubricants. See
Recommended Fluids and
Lubricants
Wipe clean all dirt and debris from
grease fittings before applying
grease. If the fitting is not cleaned,
dirt can be pushed into the
component with the grease. Always
fill grease to the point where old
grease and contaminants are forced
out from the part and only new
grease comes out. If a fitting does
not accept lubrication due to
damage or internal stoppage,
replace with a new fitting. Remove
excess grease from fittings and
other surfaces after applying
grease.
