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 affe cting operation
The smart access system with push-button st art uses weak radio wa ves. In the following
situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-but ton start, wireless remote
control and engine immobilizer sy stem from operating properly.
(Ways of coping:  P. 518)●

Near a TV tower, electric power plant, gas st ation, radio station, la rge display, airport or
other facility that generates strong radio wave s or electrical noise●
When carrying a portable radio, cellular phone, cordless phone or other wireless com-
munication device ●
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
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems ●

Operation of each component
RC F_U ■
Note 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 near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened.
• The electronic key is on th e instrument panel, rear pack age tray or floor, or in the
door pockets or glove box when the engine is started or engine switch modes are
changed. ●
Do not leave the electronic key on top of th e 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 an d the doors will become lockable from the
outside, possibly trapping the electronic key inside the vehicle. ●
As long as the electronic key is within th e effective range, the doors may be locked or
unlocked by anyone. However, only the door s detecting the electronic key can be used
to unlock the vehicle. ●
Even if the electronic key is not inside the vehicle, it may be possible to start the engine
if the electronic key is near the window. ●
The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash, when th e electronic key is with in the effective range.
(The doors will automatically be locked af ter approximately 60 seconds if the doors
are not opened and closed.) ●
If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.) ●
Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation. ●
When the lock operation is performed using the lock sensor, recognition signals will be
shown up to two consecutive times. After this, no recognition signals will be given.●
If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. In this case, follow th e following correction
procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle. (Take
care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. (  P. 158)●
If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the mult i-information display and a buzzer will
sound outside the vehicle. To turn of f the alarm, lock both side doors.●
The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again. ●
A sudden handle operation or a handle operation immediately after entering the effec-
tive range may prevent the doors from bein g unlocked. Touch the door unlock sensor
and check that the doors are unlocked before pulling the door handle again.●
Unlocking the vehicle may take more time if another electronic key is within the effec-
tive range.

Driving in the rain ●
Drive carefully when it is ra ining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery. ●
Drive carefully when it starts to rain, beca use the road surface will be especially slip-
pery. ●
Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and th e road surface, preventing the steering and
brakes from operating properly. ■
Engine speed while driving
In the following conditions, th e engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indica te sudden acceleration.●
The vehicle is judged to be driving uphill or downhill ●
When the accelerato r pedal is released●
When the brake pedal is depressed while sport mode is selected ■
Restraining the engine output (Brake Override System)●
When the accelerator and brake pedals are depressed at the same time, the engine
output may be restrained. ●
A warning message is displayed on the mult i-information display while the system is
operating. (  P. 477)■

RC F_U WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
If a brake pad wear warning message is displayed (RC F)
Have the brake pads visually checked and replaced by your Lexus dealer as soon as
possible.
Rotor damage may result if the pads are not replaced when needed.
Moderate levels of the brake pad and disc wear allow enhanced braking power. As a
result, the discs may wear more quickly than conventional brake discs. Therefore, when
replacing the brake pads, Lexu s recommends that you also have the thickness of the
discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded. ■
When the vehicle is stopped ●
Do not race the engine.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident. ●
In order to prevent accidents due to the ve hicle 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 r acing 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.
