The mechanical key can only be
inserted in one direction, as the key
only has grooves on one side. If the
key cannot be inserted in a lock
cylinder, turn it over and re-attempt
to insert it.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the entry
function does not operate properly,
you will need the mechanical key.
The following keys are provided with the vehicle.

08_IS F_U_(L/O_0711)
■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start from
operating properly:
(Ways of coping: →P. 3 8 6 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When another wireless key (that emits radio waves) is being used nearby
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
●If window tint with a metallic content or metallic objects are attached to the rear

■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.

●The vehicle is locked/unlocked using the mechanical key. ( →P. 3 8 6 )
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The battery becomes depleted even if
the electronic key is not used.) If the smart access system with push-button start
or the wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. ( → P. 3 1 6 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field.
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Glass top ranges
•Table lamps
■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected correctly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not function.)
