●Collision from the rear
●Vehicle rollover
For Russia and Kazakhstan: The SRS curtain shield airbags do not ge nerally inflate if the
vehicle is involved in a rear collision, if it pitches end over end, or if it is involved in a low-speed side or low-speed frontal colli-
sion.
●Collision from the rear
●Pitching end over end
■When to contact any authorized Lexus retailer or Lexus authorized repairer, or
any reliable repairer
In the following cases, the vehicle will
require inspection and/or repair. Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer
as soon as possible.
●Any of the SRS airbags have been
inflated.
●The front of the vehicle is damaged or
deformed, or was involv ed in an accident that was not severe enough to cause the SRS front airbags to inflate.
●A portion of a door or its surrounding area is damaged, deformed or has had a hole made in it, or the vehicle was
involved in an accident that was not severe enough to cause the SRS side and curtain shield airbags to inflate.
●The pad section of the steering wheel, dashboard near the front passenger air-
bag or lower portion of the instrument panel is scratched, cracked, or otherwise damaged.
●The surface of the seats with the SRS side
airbag is scratched, cracked, or other- wise damaged.

inside is scratched, cracked, or otherwise damaged.
WARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags. Failure to do so may cause death or seri-ous injury.
●The driver and all passengers in the
vehicle must wear their seat belts properly.The SRS airbags are supplemental
devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.Since the risk zone for the driver’s air-
bag is the first 50 - 75 mm (2 - 3 in.) of inflation, placing yourself 250 mm (10 in.) from your driver airbag provides
you with a clear margin of safety. This distance is measured from the center of the steering wheel to your breast-
bone. If you sit less than 250 mm (10 in.) away now, you can change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) distance, even with the driver seat
all the way forward, simply by reclining the back of the seat somewhat. If reclining the back of your seat makes it
hard to see the road, raise yourself by using a firm, non-slippery cushion, or raise the seat if your vehicle has that
feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag toward your chest instead of your head
and neck.
The seat should be adjusted as recom-
mended above, while still maintaining
control of the foot pedals, steering wheel,
and your view of the instrument panel
controls.
●The SRS front passenger airbag also
deploys with considerable force, and can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passen- ger seat should be as far from the air-bag as possible with the seatback
adjusted, so the front passenger sits upright.

For safety and security
WARNING
●Improperly seated and/or restrained infants and children can be killed or seriously injured by a deploying airbag.
An infant or child who is too small to use a seat belt should be properly secured using a child restraint system.
Lexus strongly recommends that all infants and children be placed in the rear seats of the vehicle and properly
restrained. The rear seats are safer for infants and children than the front pas-senger seat. ( P.48)
●Do not sit on the edge of the seat or
lean against the dashboard.
●Do not allow a child to stand in front of
the SRS front passenger airbag unit or sit on the knees of a front passenger.
●Do not allow the front seat occupants to hold items on their knees.
●Do not lean against the door, the roof side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seat toward the door or put their head or hands outside the vehi-cle.
●Do not attach anything to or lean any-thing against areas such as the dash-
board, steering wheel pad and lower portion of the instrument panel. These items can become projectiles
when the SRS driver, front passenger and knee airbags deploy.

1-1. For safe use
WARNING
●Do not attach anything to areas such as a door, windshield, side window, front or rear pillar and roof side rail.
●Do not hang coat hangers or other hard objects on the coat hooks. All of
these items could become projectiles and may cause death or serious injury, should the SRS curt ain shield airbags
deploy.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to remove it.
●Do not use seat accessories which
cover the parts where the SRS side air- bags inflate as they may interfere with inflation of the SRS airbags. Such
accessories may prevent the side air- bags from activating correctly, disable the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components or the doors. Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component
parts immediately after the SRS air- bags have deployed (inflated) as they may be hot.
●If breathing becomes difficult after the
SRS airbags have deployed, open a door or window to allow fresh air in, or leave the vehicle if it is safe to do so.
Wash off any residue as soon as possi- ble to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad
and front and rear pillar garnishes are damaged or cracked, have them replaced by any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.
■Modification and disposal of SRS air-bag system components
Do not dispose of your vehicle or per- form any of the following modifications
without consulting any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer. The SRS airbags
may malfunction or deploy (inflate) acci- dentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or
replacement of the steering wheel, instrument panel, dashboard, seats or seat upholstery, front, side and rear pil-
lars, roof side rails, door panels, door trims or door speakers
●Modifications to the door panel (such
as making a hole in it)
●Repairs or modifications of the front fender, front bumper, or side of the occupant compartment
●Installation of a grille guard (bull bars,
kangaroo bar, etc.), snow plows, winches or roof luggage carrier
●Modifications to the vehicle’s suspen-sion system
●Installation of electronic devices such
as mobile two-way radios (RF-trans- mitter) and CD players

For safety and security
WARNING
■When installing a child restraint sys- tem
For safety reasons, always install a child restraint system in a rear seat. In the event that the rear seat cannot be used,
the front seat can be used as long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment (inflation) may cause serious
injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off sys- tem is set to “ON”.If it is left off, the airbag may not deploy in
the event of an accident, which may result in serious injury or even death.
Riding with children
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the window lock switch to
avoid children operating the
power window accidentally.
( P.152)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, seats
etc.
WARNING
■When children are in the vehicle
Never leave children unattended in the vehicle, and never allow children to have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the windows or other features of the vehicle. In addi-
tion, heat build-up or extremely cold temperatures inside the vehicle can be fatal to children.

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.
