When all the side doors and back door
are unlocked simultaneously with a key,
the front personal lights and engine switch
light will come on and remain on for about
15 seconds before fading out. (For details,
see “Front personal lights” on page 179
and “Engine (ignition) switch light” on
page 181 in Section 1−5.)
If the back door opener does not operate,
see “If you cannot operate back door
opener” on page 494 in Section 4.
If the battery is disconnected or run
down, the back door will be automatically
locked after you reconnect, replace or re-
charge the battery. Be careful not to lock
your keys in the vehicle.

strap can be used to make the reach
easier.

try pulling it up to make sure it is secure-
ly closed.

ing. This not only keeps the luggage
from being thrown out but also pre-
vents exhaust gases from entering
the vehicle.

dampers, do not apply any force,
paint or let any other foreign matter
on them.

CAUTION
Avoid reclining the seatback any
more than needed. The seat belts pro-
vide maximum protection in a frontal
or rear collision when the passengers
are sitting up straight and well back
in the seats. If you are reclined, the
lap belt may slide past your hips and
apply restraint forces directly to the
abdomen or your neck may contact
the shoulder belt. In the event of a
frontal collision, the more the seat is
reclined, the greater the risk of death
or personal injury.
For access to the third seat, perform
the following procedure.
Fold down the seatback while pulling the
seatback angle adjusting lever or strap
and swing up the seat.
After passengers are in, return the seat
until it locks securely, and lift up the seat
back by pulling the lever or strap.
CAUTION
After returning the seat, make sure
the seat is securely locked by push-
ing forward and rearward on the top
of the seatback or by trying to pull
up the edge of the bottom cushion.
Failure to do so will prevent seat belt
from operating properly.
