celed.
QSystem maintenance
The vehicle has a maintenance-free type
immobilizer system.
QConditions that may cause the system to
malfunction
OIf the grip portion of the key is in contact with a metallic object
OIf the key is in close proximity to or touch-
ing a key registered to the security sys-
tem (key with a built-in transponder chip)
of another vehicleImmobilizer system
The vehicle’s keys have built-in
transponder chips that prevent the
hybrid system from starting if a key
has not been previously registered
in the vehicle’s on-board computer.
Never leave the keys inside the
vehicle when you leave the vehicle.
This system is designed to help pre-
vent vehicle theft but does not guar-
antee absolute security against all
vehicle thefts.

Before driving
QBattery-saving function
The battery-saving function will be acti-
vated in order to prevent the electronic key
battery and the 12-volt battery from being
discharged while the vehicle is not in opera-
tion for a long time.
OIn the following situations, the smart
access system with push-button start may
take some time to unlock the doors.
• The electronic key has been left within
approximately 6 ft. (2 m) of the outside of
the vehicle for 10 minutes or longer.
• The smart access system with push-but-
ton start has not been used for 5 days or
longer.
OIf the smart access system with push-but-
ton start 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 han-
dle, or use the wireless remote control or
mechanical key, to unlock the doors.
QTurning an electronic key to battery-
saving mode
OWhen battery-saving mode is set, battery
depletion is minimized by stopping the
electronic key from receiving radio
waves.
Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button
start cannot be used. To cancel the func-
tion, press any of the electronic key but-
tons.
OElectronic keys that will not be used for
long periods of time can be set to the bat-
tery-saving mode in advance.
QConditions affecting operation
The smart access system with push-button
start uses weak radio waves. In the follow-
ing situations, the communication between
the electronic key and the vehicle may be
affected, preventing the smart access sys-
tem with push-button start, wireless remote
control and immobilizer system from oper-
ating properly.
(Ways of coping:  P.389)

3867-2. Steps to take in an emergency
One of the following may be the cause
of the problem:
The electronic key may not be func-
tioning properly. ( P.390)
 There may not be sufficient fuel in
the vehicle’s tank.
Refuel the vehicle. ( P.174)
 There may be a malfunction in the
immobilizer system. ( P.67)
 There may be a malfunction in the
steering lock system.
 The hybrid system may be malfunc-
tioning due to an electrical problem
such as electronic key battery
depletion or a blown fuse. However,
depending on the type of malfunc-
tion, an interim measure is available
to start the hybrid system.
 For vehicles sold in except Canada:
There is a possibility that the tem-
perature of the hybrid battery (trac-
tion battery) is extremely low
(approximately below -22°F [-
30°C]). ( P.63, 148)
WARNING
QSpeed limit when using the compact
spare tire
Do not drive at speeds in excess of 50
mph (80 km/h) when a compact spare
tire is installed on the vehicle.
The compact spare tire is not designed
for driving at high speeds. Failure to
observe this precaution may lead to an
accident causing death or serious injury.
QAfter using the tools and jack
Before driving, make sure all the tools
and jack are securely in place in their
storage location to reduce the possibility
of personal injury during a collision or
sudden braking.
NOTICE
QBe careful when driving over bumps
with the compact spare tire installed
on the vehicle
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires. Be
careful when driving over uneven road
surfaces.
QDriving with tire chains and the com-
pact spare tire
Do not fit tire chains to the compact
spare tire.
Tire chains may damage the vehicle
body and adversely affect driving perfor-
mance.
QWhen replacing the tires
When removing or fitting the wheels,
tires or the tire pressure warning valve
and transmitter, contact your Lexus
dealer as the tire pressure warning valve
and transmitter may be damaged if not
handled correctly.

Reasons for the hybrid system not
starting vary depending on the situ-
ation. Check the following and per-
form the appropriate procedure:
