Wireless remote control battery depletion
The standard battery life is 1 to 2 years. (The battery becomes depleted
even if the wireless remote control is not used.) If the wireless remot\
e control
function does not operate, the battery may be depleted. Replace the battery
when necessary. ( P. 577)
■ If the wireless remote control does not operate
Locking and unlocking the doors: Use the key. ( P. 49)
■ Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
■ Alarm (if equipped)
Using the wireless remote control to lock the door will set the alarm sy\
stem.
(P. 117)
■ Conditions affecting operation
The wireless remote control function may not operate normally in the follow-
ing situations.
●Near a TV tower, radio station, electr ic power plant, airport or other facil-
ity that generates strong radio waves
● When carrying a portable radio, cell ular phone or other wireless commu-
nication device
● When multiple wireless keys are in the vicinity
● When the wireless key has come into contact with, or is covered by a
metallic object
● When a wireless key (that emits radio waves) is being used nearby
● When the wireless key has been left near an electrical appliance such as
a personal computer
■ When riding in an aircraft
When bringing a wireless remote control onto an aircraft, make sure you do
not press any buttons on the wireless remote control while inside the aircraft
cabin. If you are carrying a wireless remote control in your bag etc, ensure
that the buttons are not likely to be pressed accidentally. Pressing a button
may cause the wireless remote control to emit radio waves that could inter-
fere with the operation of the aircraft.

72 1-3. Adjustable components (seats, mirrors, steering wheel)
■Retained accessory power
Each memorized position (except for the tilt and telescopic steering column)
can be activated within 30 seconds after the driver’s door is opened, even if
the key is not in the engine switch.
■ If any position memory button is pushed while the adjustments are
being made
The operation will stop. To reactivate the system, push the button (“1” or “2”)
again.
■ If the battery is disconnected
The memorized positions must be reset because the computer’s memory is
erased when the battery is disconnected.
CAUTION
■Seat adjustment caution
Take care during seat adjustment that the seat does not strike the rear pas-
senger or squeeze your body against the steering wheel.
If this happens, you can stop the movement by pressing another seat posi-
tion memory button.

652 5-2. Steps to take in an emergency
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine is turned
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ When the battery is removed or discharged
●The moon roof must be initialized. ( P. 107)
● Flex-fuel vehicles: The information recorded in the computer will be
cleared, which may cause the engine to run roughly and reduce driving
performance for a while when the engine is first started. In this case, wait
until the engine runs normally.
If the vehicle is running on E85, the engine may stall.
In this case, restart the engine, repeatedly if necessary.
● Make sure that the key is not inside the vehicle when recharging or
replacing the battery. The key may be locked in the vehicle if the alarm is
activated. ( P. 118)
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
