PressurechamberOperation of the Auto Tensioner
WHEN THE BELT TENSION HAS INCREASED
(1) The tensioner arm pushes the piston in the direction shown
by
arrow @, causing the hydraulic pressure in the pressurechamber to build up.
(2) The check ball closes.
(3) The oil inthepressure chamber is compressed by the
piston, which causes a small amount of oil to gradually leak
through the clearance between the piston and cylinder into
the reservoir chamber. This causes the piston to move
slowly in the direction shown by arrow
@.
(4) The piston stops moving when the load in the direction @balances the spring tension, which determines the load,
i.e., tension, applied to the belt.
WHEN THE BELT TENSION HAS DECREASED
(1) The piston moves in the direction shown by arrow @I by the
spring tension.
(2) As the piston moves, the hydraulic pressure in the pressure
chamber becomes lower than that in the reservoir cham-
ber.
(3) The check ball opens.
(41 Oil enters the pressure chamber.
(5) The piston stops moving when the belt tension balances
the spring tension, which determines the tension applied to
the belt.

Rz3The front seats are sporty
highback seats with an
integral headrestraint that hold your body in place oncurves. The driver’s seat on the higher grade model
is provided with the lumbar support that is
adjust-able in four positions.The.driver’s seat slides 260 mm (10.2 in.) I230 mm
(9.1 in.) on the front passenger’s seat].
The front passenger’s seat can be folded down to
ensure easy egress/ingress for the rear-seat pas-
sengers.

REAR SEATR23u9ABThe rear seat is for two passengers, having low
seatback and contoured seat cushions. The seat-back can be folded down to give an additional
luggage c5mpartment space.There are cushion pockets at the center, into which
the rear seat belt buckles are stored when the
seatback is folded down.
