deformed, or the vehicle was involved in an 
accident that was not severe enough to 
cause the SRS side airbags and curtain 
shield airbags to inflate.
●The pad section of the steering wheel, front 
passenger airbag cover or lower portion of 
the instrument panel is scratched, cracked, 
or otherwise damaged.
●The surface of the seats with the side air-
bag is scratched, cracked, or otherwise

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the airbags. Failure to do so may 
cause death or serious 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. The National 
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver airbag is th e first 2 - 3 in. (50 - 75 mm) of inflation, 
placing yourself 10 in. (250 mm) 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 breastbone. If you sit less than 10 in. (250 mm) 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. Al though vehicle designs vary, many driv-
ers can achieve the 10 in. (250 mm) distan ce, 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, ti lt it downward. This points the airbag 
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering  wheel, and your view of the instrument 
panel controls.

CAUTION
■SRS airbag precautions
●If breathing becomes difficult after the SRS airbag has 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 possible  to prevent skin irritation. 
●If the areas where the SRS airbags are stored, such as the steering wheel pad and 
front pillar garnish, are damaged or cracked, have them replaced by your Lexus 
dealer.
●Do not place anything, such as a cushion, on the front passenger’s seat. Doing so 
will disperse the passenger’s weight, wh ich prevents the sensor from detecting 
the passenger’s weight properly. As a result, the SRS front passenger airbag may 
not deploy in the event of a collision.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the followin g modifications with-
out consulting your Lexus dealer. The  SRS airbags may malfunction or deploy 
(inflate) accidentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replac ement of the steering wheel, instrument 
panel, dashboard, seats or seat upholstery,  front, side and rear pillars or roof side 
rail
●Repairs or modifications of the front fender , front bumper, or side of the occupant 
compartment
●Installation of snow plows, winches, etc.  to the front grille (bull bars, kangaroo bar 
etc.)
●Modifications to the vehi cle’s suspension system
●Installation of electronic devices such as mobile two-way radios or CD players
●Modifications to your vehicle for a person with a physical disability

CAUTION
■When driving the vehicle
●Do not shift the shift lever to “N” while the vehicle is moving.
Doing so may cause the engine brake not to operate properly and lead to an 
accident.
●Do not turn the hybrid system off while driving.  
The power steering and brake actuator will  not operate properly if the hybrid sys-
tem is off.
●Use engine braking (downshift) to maintain a safe speed when driving down a 
steep hill.  
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( P. 144)
●When stopped on an inclined surface, use the brake pedal and parking brake to 
prevent the vehicle from rolling backwa rd or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when 
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering  wheel, the seat, or the inside or outside 
rear view mirrors while driving. 
Doing so may result in a loss of vehicle  control that can cause accidents that may 
result in death or serious injury.
●Always check that all passengers’ arms, heads or other parts of their bodies are 
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do 
not drive over 85 mph (140 km/h) unless  your vehicle has high-speed capability 
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and 
possible injury. Be sure to consult a tire dealer to determine whether the tires on 
your vehicle are high-speed capability tires or not before driving at such speeds.
●The driver should pay attention to pedest rians when the vehicle is powered only 
by the electric motor (traction motor). Because there is no engine sounds, the 
pedestrians may misjudge the vehicle’s movement.

NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together 
to hold the vehicle on a hill.
■When parking the vehicle
Always put the shift lever in “P”. Failure to do so may cause the vehicle to move or 
the vehicle may accelerate suddenly if the accelerator pedal is accidentally 
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long 
time.  
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc. 
■If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed. 
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced 
front braking power. As a result, the discs  may wear more quickly than conventional 
brake discs. Therefore, when replacing the brake pads, Lexus 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 
that of the brake discs are exceeded.
