Seatback angle
To recline the seatback:
1. Lean forward slightly and lift up the seatback lever.
2. Carefully lean back on the seat and adjust the seatback to the position
you desire.
3. Release the lever and make sure the seatback is locked in place. (The lever
MUST return to its original position for
the seatback to lock.)
Reclining seatback
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the protection of
your restraint system (seat belts and air
bags) is greatly reduced by reclining your
seatback.
WARNING
NEVER ride with a reclined seatback
when the vehicle is moving.
Riding with a reclined seatback
increases your chance of serious or fatal
injuries in the event of a collision or
sudden stop.
Drivers and passengers should ALWAYS
sit well back in their seats, properly
belted, and with the seatbacks upright. Seat belts must be snug against your
hips and chest to work properly. When
the seatback is reclined, the shoulder
belt cannot do its job because it will not
be snug against your chest. Instead,
it will be in front of you. During an
accident, you could be thrown into the
seat belt, causing neck or other injuries.
The more the seatback is reclined,
the greater chance the passenger’s hips will slide under the lap belt or the
passenger’s neck will strike the shoulder belt.
ODN8039004
Seat cushion height
To change the height of the seat cushion: •
Push down on the lever several times,
to lower the seat cushion.
• Pull up on the lever several times, to
raise the seat cushion.

Seat Belt Restraint System
WARNING
Improperly positioned seat belts may
increase the risk of serious injury
in an accident. Take the following
precautions when adjusting the seat belt: • Position the lap portion of the seat
belt as low as possible across your
hips, not on your waist, so that it fits
snugly.
• Position one arm under the shoulder
belt and the other over the belt, as
shown in the illustration.
• Always position the shoulder belt
anchor into the locked position at the
appropriate height.
• NEVER position the shoulder belt
across your neck or face. Seat Belt-Driver’s 3-point system
with emergency locking retractor
OHI038140
To fasten your seat belt:
Pull the seat belt out of the retractor and
insert the metal tab (1) into the buckle
(2). There will be an audible “click” when
the tab locks into the buckle.
OHI038137
You should place the lap belt (1) portion
across your hips and the shoulder belt (2)
portion across your chest.
The seat belt automatically adjusts to the
proper length after the lap belt portion
is adjusted manually so that it fits snugly
around your hips. If you lean forward in
a slow, easy motion, the belt will extend
and move with you.
If there is a sudden stop or impact, the
belt will lock into position. It will also lock
if you try to lean forward too quickly.

Seats & Safety System

NOTICE
If you are not able to smoothly pull
enough of the seat belt out from the
retractor, firmly pull the seat belt out
and release it. After release, you will be
able to pull the belt out smoothly.
Height adjustment
You can adjust the height of the shoulder
belt anchor to one of the three different
positions for maximum comfort and
safety. The shoulder portion should be
adjusted so it lies across your chest and
midway over your shoulder nearest the
door, not over your neck. To adjust the
height of the seat belt anchor, lower
or raise the height adjuster into an
appropriate position.
„„Front seat
ODN8039072L
To raise the height adjuster, pull it up
(1). To lower it, push it down (3) while
pressing the height adjuster button (2).
Release the button to lock the anchor
into position. Try sliding the height
adjuster to make sure that it has locked
into position.
OHI038142
To release your seat belt:
Press the release button (1) in the locking buckle.
When it is released, the belt should
automatically draw back into the
retractor. If this does not happen, check
the belt to be sure it is not twisted, then try again.
Rear Seat Belt – Passenger’s 3-point
system with convertible locking
retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed
in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a convertible
retractor is also installed in the front
passenger seat position, NEVER place
any infant/child restraint system in the
front seat of the vehicle.
