■Before programming HomeLink®
During programming, it is possible
that garage doors, gates, or other
devices may operate. For this rea-
son, make sure that people and
objects are clear of the garage door
or other devices to prevent injury or
other potential harm.
 It is recommended that a new bat-
tery be placed in the remote control
transmitter for more accurate pro-
gramming.
 Garage door opener motors manu-
factured after 1995 may be
equipped with rolling code protec-
tion. If this is the case, you may need
a stepladder or other sturdy, safe
device to reach the “Learn” or
“Smart” button on the garage door
opener motor.

Steps 1 through 3 must be performed
within 60 seconds, otherwise the indi-
cator light will stop flashing and pro-
gramming will not be able to be
completed.

If the system will not start even after multi-
ple attempts, contact your Lexus dealer.
If any washer does not work or the
warning message appears on the
multi-information display, the washer
tank may be empty. Add washer fluid.

3347-2. Steps to take in an emergency
RC F Owner's Manual
5Start the engine of the second vehi-
cle. Increase the engine speed
slightly and maintain at that level for
approximately 5 minutes to
recharge the battery of your vehi-
cle.
6 Open and close any of the door of
your vehicle with the engine switch
off.
7 Maintain the engine speed of the
second vehicle and start the engine
of your vehicle by turning the
engine switch to IGNITION ON
mode.
8 Once the vehicle’s engine has
started, remove the jumper cables
in the exact reverse order from
which they were connected.
Once the engine starts, have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
■Starting the engine when the battery is
discharged
The engine cannot be started by push-start-
ing.
■To prevent battery discharge
●Turn off the headlights and the audio sys-
tem while the engine is off.
●Turn off any unnecessary electrical com-
ponents when the vehicle is running at a
low speed for an extended period, such
as in heavy traffic.
■Charging the battery
The electricity stored in the battery will dis-
charge gradually even when the vehicle is
not in use, due to natural discharge and the
draining effects of certain electrical appli-
ances. 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.)
■When recharging or replacing the bat-
tery
●In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
battery is discharged. Use the wireless
remote control or the mechanical key to
lock or unlock the doors.
●The engine may not start on the first
attempt after the battery has recharged
but will start normally after the second
attempt. This is not a malfunction.
●The engine switch mode is memorized by
the vehicle. When the battery is recon-
nected, the system will return to the
mode it was in before the battery was dis-
charged. Before disconnecting the bat-
tery, turn the engine switch off.
If you are unsure wh at mode the engine
switch was in before the battery dis-
charged, be especially careful when
reconnecting the battery.
■When replacing the battery
●Use a battery that conforms to European
regulations.
●Use a battery that tha case size is same as
the previous one (LN3), 20 hour rate
capacity (20HR) is equivalent (70Ah) or
greater, and performance rating (CCA)
is equivalent (592A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not
used is a short time, battery may dis-
charge and the engine may not be able to
start.
●For details, consult your Lexus dealer.
