■Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
■Conditions affecting operation
The smart access system with push-button start, wireless remote control and engine
immobilizer system use weak radio waves. In the following situations, the communication
between the electronic key and the vehicle ma y be affected, preventing the smart access
system with push-button star t, wireless remote control and engine immobilizer system
from operating properly. (Ways of coping: P. 684)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that generates strong radio wave s or electrical noise
●When the electronic key is in contact with, 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
• Portable radio, cellular phone, cordle ss phone or other wireless communication
devices
• Another vehicle’s electronic key, another electronic key of your vehicle, or a wireless
key that emits radio waves
• Personal computers or person al 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
●When the vehicle is parked in a pay parking spot where radio waves are emitted
Press twice while pressing and holding .
Confirm that the electronic key indicator flashes
4 times.
While the battery-saving mode is set, the smart
access system with push
-button start cannot be

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the shift lever is in any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake as neces-
sary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, alwa ys depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, sp ray cans, or soft drink cans in the vehicle
when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cau se the plastic lenses and plastic mate-
rial of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the
vehicle, and may also cause a short circui t in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as
the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windsh ield or windows. Do not place containers
such as air fresheners on th e instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, ca using a fire in the vehicle.
●Do not leave a door or window open if th e curved glass is coated with a metallized
film such as a silver-colored one. Reflecte d sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the engine and lock the
vehicle.
Do not leave the vehicle unattend ed while the engine is running.
If the vehicle is parked with the shift leve r in P but the parking brake is not set, the
vehicle may start to move, possibly leading to an accident.
●Do not touch the exhaust pipes while the engine is running or immediately after turn-
ing the engine off.
Doing so may cause burns.
