– CONTINUED –
yDo not allow the retractor to roll up the seat-
belt too quickly. Otherwise, the metal tongue
plates may hit against the trim, resulting in
damaged trim. y Have the seatbelt fully rolled up so that the
tongue plates are neatly stored. A hanging
tongue plate can swing and hit against the trim
during driving, causing damage to the trim. „
Seatbelt maintenance
To clean the seatbelts, use a mild soap and lukewarm
water. Never bleach or dye the belts because this
could seriously affect their strength.
Inspect the seatbelts and attachments including the webbing and all hardware periodically for cracks, cuts,
gashes, tears, damage, loose bolts or worn areas. Re-
place the seatbelts even if only minor damage is
found.
y Keep the belts free of polishes, oils, chemi-
cals and particularly battery acid. y Never attempt to make modifications or
changes that will prevent the seatbelt from op-
erating properly.
