Operation of each component
GS350_200t_GS F_OM_OM30E87E_(EE)
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and engine immobilizer system
from operating properly. (Ways of coping: →P. 5 8 8 )
●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 the electronic key is in contact wi th, or is covered by the following metallic
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 other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key together with the following devices that emit radio
waves
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or me tallic objects are attached to the rear win-
dow
●When the electronic key is placed near a battery charger or electronic devices
Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.

■Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily drops, the
electric power steering system warning light may come on and the warning buzzer may
sound.
■When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check that the tire infla-
tion pressure is at the specifie d level and carry out initialization.
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural air
leaks and tire inflation pressure changes caused by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning light
will not turn off even though the flat tire has been replaced with the spare tire.
Vehicles with full-size spare tire: The spare tire is also equipped with a tire pressure warn-
ing valve and transmitter. The tire pressure warn ing light will turn on if the tire inflation
pressure of the spare tire is low. If a tire go es flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
