The main SRS airbag system and Pop Up Hood components are shown above.
The SRS airbag system and Pop Up Hood are controlled by the airbag sensor
assembly. As the airbags deploy, a chemical reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the occupants.
When the Pop Up Hood is activated, a non-toxic gas is released due to a chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: P. 53)

WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS 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 seri-
ous injury especially if the driv er is very close to the airbag.
Since the risk zone for the driver’s airbag 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 breastbone. 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 com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, 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 recommend ed above, while still maintaining control
of the foot pedals, steering wheel, and your view of the instrument panel controls.

■“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in the sys-
tem. Have the vehicle inspected by any au thorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
●Neither “ON” nor “OFF” comes on.
●The indicator light does not change when the airbag manual on-off switch is switched
to “ON” or “OFF”.
WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint 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 system 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.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driven within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the front bumper. Also, depending on the impact
conditions or vehicle speed, the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may operate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or falling object
Pop Up Hood operational conditions
WARNING
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has oper-
ated will further raise the h ood and may cause an injury.
Do not drive with the hood raised, as doing so may block the driver’s vision, possibly
causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be lowered by
hand, doing so may deform the hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus retailer or Lexus authorized repairer , or any reliable repairer. If the Pop Up
Hood has operated, stop the vehicle in a safe place and contact authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift-
ers may be hot and burn you.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
Exhaust gases include harmful carbon monox ide (CO), which is colorless and odorless.
Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehicle even when the trunk lid is closed, open the
windows and have the vehicle inspected at any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
engine.
●Do not leave the vehicle with the engine on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
●Do not leave the engine running in an area with snow build-up, or where it is snowing.
If snowbanks build up around the vehicle while the engine is running, exhaust gases
may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack caused
by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by any authorized Le xus retailer or Lexus authorized repairer,
or any reliable repairer.

WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on when
you start the engine, this could mean that these systems are not available to help pro-
tect you in an accident, which could result in death or serious injury. Have the vehicle
inspected by any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer immediately if this occurs.
