WARNING
●Never use a rear-facing child restraint system on the front passenger seat when the airbag manual on-off switch
is on. ( P.46) The force of the rapid inflation of the front passenger airbag can cause
death or serious injury to children in the event of an accident.
●There is a label(s) on the passenger side sun visor, indicating it is forbidden to attach a rear-facing child restraint
system to the front passenger seat. Details of the label(s) are shown in the illustration below.

WARNING
WARNING
■When installing a child restraint sys-
tem
●Only put a forward-facing child
restraint system on the front seat when unavoidable. When installing a for-
ward-facing child rest raint on the front passenger seat, move the seat as far back as possible. Failing to do so may
result in death or serious injury if the airbags deploy (inflate).
●Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat, front or rear pillars or roof side rails from which the SRS side airbags or
SRS curtain shield airbags deploy even if the child is seated in the child restraint system. It is dangerous if the
SRS side and curtain shield airbags inflate, and the impact could cause death or serious injury to the child.
●When a junior seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away from the child’s neck, but not so that it
could fall off the child’s shoulder.
●Use child restraint system suitable to the age and size of the child and install it to the rear seat.

4-5. Using the driving support systems
■ECB (Electronically Controlled
Brake System)
The electronically controlled system
generates braking force correspond-
ing to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the
brakes are applied suddenly, or if the
brakes are applied while driving on a
slippery road surface
■Brake assist
Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning on
slippery road surfaces
■Secondary Collision Brake (if
equipped)
When the airbag sensor detects a colli-
sion, the brakes and brake lights are
automatically controlled to reduce the
vehicle speed and that helps reduce
the possibility of further damage due to
a secondary collision.
■TRC (Traction Control)
Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
■Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
■VGRS (Variable Gear Ratio Steer-
ing) (if equipped)
Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement
■DRS (Dynamic Rear Steering) (if
equipped)
Contributes to the turning characteris-
tics and responsiveness of the vehicle
by slightly adjusting the rear wheel
angle of the vehicle in accordance with
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel
■AVS (Adaptive Variable Suspen-
sion System)
By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
Driving assist systems
To keep driving safety and perfor-
mance, the following systems oper-
ate automatically in response to
various driving situations. Be aware,
however, that these systems are
supplementary and should not be
relied upon too heavily when oper-
ating the vehicle.

4-5. Using the driving support systems
Driving
■EPS, VGRS and DRS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be heard. This does not indicate a malfunction.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch
is turned off
●If only the TRC system is turned off, the
TRC will turn on when vehicle speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed increases.
■Secondary Collision Brake operating
conditions
The vehicle speed is approximately 10 km/h
(6 mph) or more and the airbag sensor detects a collision. (The Secondary Colli-sion Brake will not operate when the vehicle
speed is below approximately 10 km/h [6 mph].)
■Secondary Collision Brake automatic
cancellation
The Secondary Collision Brake is automati-
cally canceled in the following situations:
●The vehicle speed drops below approxi-
mately 10 km/h (6 mph)
●A certain amount of time elapses during
operation
●The accelerator pedal is depressed a
large amount
■If “Check Secondary Collision Brake system” is displayed on the multi-infor-mation display
The system may be malfunctioning. Have the vehicle inspected at any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Reduced effectiveness of the EPS sys-tem
The effectiveness of the EPS system is
reduced to prevent the system from over- heating when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive steering input or stop the vehicle and turn
the engine off. The EPS sys- tem should return to normal within 10 min-utes.
■Operating conditions of emergency
brake signal
When the following three conditions are
met, the emergency brake signal will oper- ate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h
(35 mph).
●The brake pedal is depressed in a manner
that cause the system to judge from the vehicle deceleration that this is a sudden braking operation.
■Automatic system cancelation of emer-
gency brake signal
The emergency brake sign al will turn off in
any of the following situations:
●The emergency flashers are turned on.
●The brake pedal is released.
●The system judges from the vehicle deceleration that is not a sudden braking
operation.
WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick roads.

occur synchronized with the operation of the airbag system. (If the vehicle is bumped from behind, etc.)
●The airbag may not inflate even in case
of an accident, if it does not involve high impact. In such cases, the system may not make emergency calls auto-
matically. The system may also not make automatic emergency calls even if the airbag has been inflated. If any of
these should occur, please report to the Public Safety Answering Point (PSAP) by operating the “SOS” but-
ton.
●For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mishandling of th e steering wheel, which may lead to unexpected acci-
dents. Stop the vehicle and confirm the safety of the area before making the Emer-
gency Call.
●When changing fuses, please use fuses that correspond to the described stan-dard.
If you use fuses other than those described, it may cause ignition or smoke in the circuit and may lead to a
fire.
