page 102).

SmartKey and start the engine without in-
serting the SmartKey in the starter switch.
Pull an outside door handle.
All turn signal lamps flash once.
An acoustic signal sounds once.
The locking knobs in the doors
move up.
The anti-theft alarm system is dis-
armed.
Get in the vehicle.
For more information, see “SmartKey with
KEYLESS-GO*” (
page 105).
i
Opening a door causes the window on that
door to open slightly. They will return to the up
position when the door is closed.
!
The side windows will not open or close if
the battery is discharged or the windows are cov-
ered with ice. As a result, you may no longer be
able to properly close the door. Do not attempt
to force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.
Warning!
G
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.i
To unlock the vehicle, the SmartKey with
KEYLESS-GO must be outside the vehicle, no fur-
ther than approximately 3 feet (1 meter) away
from the door.

Adjusting
Adjusting
SeatsWarning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
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 seat
backrest in an excessively reclined position
as this 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 fatal injuries. The seat back and seat belts
provide the best restraint when the wearer
is in a nearly upright position and belts are
properly positioned on the body.
Warning!
G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 48).
Observe the following points:
Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel.
Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far to the rear as pos-
sible, consistent with ability to properly
operate controls.
Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.
Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open. Therefore, do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could re-
sult in an accident and/or serious personal
injury.
