(with shoulder belt height adjustment)
Adjust the head restraint so that the upper portion
of the shoulder belt is located as close as possible to
the middle of the shoulder. The head restraint can
be tilted forward by hand.
Note:
To prevent the backrest from touching the soft top
storage compartment cover when the seat is moved
back, the backrest will automatically move to a more
upright position.
When reclining the backrest, the seat will automatically
move forward to prevent the backrest from touching the
soft top storage compartment cover.
Wa r n i n g !
When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle.The power seats can also be operated with a door
open. Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may cause
serious personal injury.
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.Never ride in a moving vehicle with the backrest
reclined.
Sitting in an excessively reclined position can be
dangerous. You could slide under the seat belt in a
collision. If you slide under it, the belt would apply
force at the abdomen or neck. That could cause
serious or even fatal injuries. The backrest and seat
belt provide the best restraint when the wearer is
in an upright position and the belt is properly
positioned on the body.The rear storage area should never be occupied by
passengers since the vehicle is a 2 seater.
Fu rth ermore, there i s a ri sk of inju ry i n the rear by
adjusting the power assisted front seats.Never place hands under seat or near any moving
parts while a seat is being adjusted.

When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time, or if the battery charge is low. When this occurs,
the indicator lamp in the switch will blink (both
indicator lamps blink during rapid seat heating mode).
The seat heaters will switch on again automatically as

Seat belts and integrated restraint system
Your vehicle is equipped with lap-shoulder seat belts,
emergency tensioning retractors for the seat belts, as
well as airbags and knee bolsters.
Seat belts
Important!
Laws in most states and all Canadian provinces require
seat belt use.
All states and provinces require use of child restraints
that comply with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a lap-
shoulder belt.
For your safety and that of your passenger we strongly
recommend their use.
Note:
For cleaning and care of the seat belts, see page 265.
Wa r n i n g !
The seat belts provide protection only with the
backrest locked in place. If the seat belt warning
lamp< does not go out, but is instead lit
continuously, then a backrest is not engaged in its
lock.Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessi vely reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.

Wa r n i n g !
Failure to wear and properly fasten and position
your seat belt greatly increases your risk of
injuries and their likely severity in an accident.
You and your passenger should always wear seat
belts.If you are ever in an accident, your injuries can be
considerably more severe without your seat belt
properly buckled. Without your seat belt buckled,
you are much more likely to hit the interior of the
vehicle or be ejected from it. You can be seriously
injured or killed.In th e sam e c rash, th e possibility of injury or death
is lessened if you are wearing your seat belt.Never let more people ride in the vehicle than there
are seat belts available. Be sure everyone riding in
the vehicle is correctly restrained with a separate
seat belt.
