TIPAs the smart key system uses
weak radio waves, the operating
range may be affected by the sur-
rounding environment.
 When the battery of the smart key
is discharged, the smart key may
not work or its operating range be-
come very small.
 If the smart key is turned off, the
vehicle will not recognize the
smart key even if it is within oper-
ating range.
 If the “ON/ ” switch,
“OFF/LOCK” switch, or “ / ”
switch are repeatedly pressed
when the smart key is out of range
or cannot communicate with the
vehicle, all switches will be tempo-
rarily disabled.
 Placing the smart key in the front
or rear storage compartment may
block communication between
the smart key and the vehicle. If
the rear trunk or front storage
compartment is locked with the
smart key inside, the smart key system may be disabled. The
smart key should always carried
on your person.
WARNING
EWA17952

The smart key shoul d b e carried
with you. Do not store it on the
vehicle.
 When the smart key is within
operatin g ran ge, exercise due
care because other people not
carryin g the smart key can start
the en gine an d operate the vehi-
cle.
EAU61647
Han dlin g of the smart key an d
mechanical keyIncluded with the vehicle is one smart
key (with a built-in mechanical key) and
one spare mechanical key with an
identification card. Keep the spare me-
chanical key and card separate from
the smart key. Should you lose or dam-
age the smart key, or when its battery
is discharged, the mechanical key will
serve as a back up. The seat can be
opened, the smart key system identifi-
cation number can be manually input,
and then the vehicle can be operated.
(See page 8-39.) We recommend that
you note down the i dentification
numb er in case of emer gency.
