Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel consumption. Use a tire that is appropriate
for the season.
Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid car-
rying unnecessary luggage. Installing a large roof rack can also cause
poor fuel consumption.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically when
cold, warming up the engine is unnecessary. Moreover, frequently driv-
ing short distances will cause the engine to repeatedly warm up, which
can lead to poor fuel consumption.

Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again. (How-
ever, depending on the location of the electronic key, the key may be
detected as being in the vehicle. In this case, vehicle may be unlocked.)
Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the vehicle battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver’s door.
In this case, take hold of the driver’s door handle, or use the wireless
remote control or the mechanical key, to unlock the doors.

Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situ-
ations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system, wireless remote con-
trol and engine immobilizer system from operating properly.
(Way of coping: P. 619)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal 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 key (that emit radio waves) is being used nearby
When carrying the electronic key together with the following devices that
emit radio waves
• A portable radio, cellular phone, cordless phone or other wireless com-
munication 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 metallic objects are attached to
the rear window
When the electronic key is placed near a battery charger or electronic
devices

Notes for the entry function
Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, luggage cover (if
equipped) or floor, or in the door pockets, glove box, accessory box of
the instrument panel, or in/near the front cup holder when:
• Except hybrid vehicle: the engine is started or “ENGINE START
STOP” switch modes are changed.
• Hybrid vehicle: the hybrid system is started or “POWER” switch
modes are changed.
Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave
reception conditions, it may be detected by the antenna outside the cabin
and the door will become lockable from the outside, possibly trapping the
electronic key inside the vehicle.
As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
Even if the electronic key is not inside the vehicle, it may be possible to
start the engine (except hybrid vehicle) or hybrid system (hybrid vehicle)
if the electronic key is near the window.
The doors may unlock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash when the electronic key is
within the effective range. (The door will automatically be locked after
approximately 30 seconds if the doors are not opened and closed.)
Gripping the door handle when wearing a glove may not unlock the door.
If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Use the wireless remote control to
unlock the doors.)
A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door
handle again.

Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
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 function may
not operate.)
If the smart entry & start system does not operate properly
Locking and unlocking the doors: Use the mechanical key. (P. 619)
Starting the engine (except hybrid vehicle) or the hybrid system (hybrid
vehicle): P. 619
Electronic key battery depletion
The standard battery life is 1 to 2 years.
If the battery becomes low, an alarm will sound in the cabin when the
engine (except hybrid vehicle) or the hybrid system (hybrid vehicle)
stops. (P. 575)
As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. (P. 505)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) 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
