In a severe frontal impact, the front airbag sensors detect
deceleration
and the system triggers the front airbag inflators.
In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side and curtain shield airbag inflators and/or the curtain shield
airbag inflator. At this time, a chemical reaction in the inflators
quickly fills the airbags with nontoxic gas to help restrain the
forward or lateral motion of the occupants.
When the SRS airbag operates, it produces a fairly loud noise
and release some smoke and residue along with nontoxic
gas. This does not indicate a fire. This gas is normally
harmless; however, for those who have delicate skin, it may
cause a minor skin irritation. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Parts of the airbag module (steering wheel hub, dashboard,
front seats, parts of the front and rear pillars and roof side) may
be hot for several minutes, but the airbags themselves will not
be hot. The airbags are designed to inflate only once.
A crash severe enough to inflate the driver and front passenger
airbags may break the windshield as the vehicle buckles. In
vehicles with a front passenger airbag, the windshield may
also be damaged by absorbing some of the force of the
inflating airbag.
CAUTION
 The SRS airbag system is designed only as a
supplement to the primary protection of the driver
side and front and rear outside passenger side seat
belt systems. The front and rear outside seat
occupants can be killed or seriously injured by the
inflating airbags if they do not wear the available seat
belts properly. During sudden braking just before a
collision, an unrestrained driver, front passenger or
rear outside passenger can move forward or
sideways into direct contact with or close proximity
to the airbag which may then deploy during the
collision. To ensure maximum protection in an
accident, the driver and all passengers in the vehicle
must wear their seat belts properly. Wearing a seat
belt properly during an accident reduces the chances
of death or serious injury or being thrown out of the
vehicle. For instructions and precautions
concerning the seat belt system, see “Seat belts” on
page 106.
 Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. 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 seat of the vehicle and properly restrained.
The rear seat is the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see “Child restraint” on page 131 .

COMFORT ADJUSTMENT
134INSTALLATION WITH 3POINT TYPE SEAT BELT
(A) Infant seat installation
An infant seat is used in rearfacing position only.
CAUTION

Never install a rearfacing child restraint system on
the front passenger seat because the force of the
rapid inflation of the front passenger airbag can
cause death or serious injury to the child.

COMFORT ADJUSTMENT
135
If your driving position is not satisfactory, install the
child restraint system on the rear right seat.1. Run the lap and shoulder belt through or around the infant
seat following the instructions provided by its manufacturer
and inserting the tab into the buckle taking care not to twist the
belt. Keep the lap portion of the belt tight.
CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt are not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally, it cannot
protect your child from injury. Contact your Lexus
dealer immediately. Do not use the child restraint
system until the seat belt is fixed.

2. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retracted even slightly, it cannot be
extended.
To hold the infant seat securely, make sure the belt is in the lock
mode before letting the belt retract.3. While pressing the infant seat firmly against the seat
cushion and seatback, let the shoulder belt retract as far as it
will go to hold the infant seat securely.

COMFORT ADJUSTMENT
137
CAUTION
Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its manufacturer.
4. To remove the infant seat, press the bucklerelease button
and allow the belt to retract completely. The belt will move
freely again and be ready to work for an adult or older child
passenger.

IN CASE OF AN EMERGENCY
263
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if you
hear a loud knocking or pinging noise, the engine has
probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in “P” and apply the
parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign
of steam or coolant. Your engine could have been seriously
damaged already. Call your Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is sign of
very high pressure.
B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning.
Check the following.
 Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in the
acceptable range, turn off the engine and call your Lexus
dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or your
vehicle overheats again, have it checked as soon as possible
by your Lexus dealer.

DOITYOURSELF SERVICEPRECAUTIONS
If you perform maintenance yourself, be sure to follow the
correct procedure given in this section.
You should be aware that improper or incomplete servicing
may result in operating problems.
Performing doityourself maintenance during the warranty
period may affect your warranty coverage. Read the separate
Lexus Warranty statement for details and suggestions.
This section gives instructions only for those items that are
relatively easy for an owner to perform. As explained in
Section 5, there are still a number of items that must be
performed by a qualified technician with special tools.
For information on tools and parts for doityourself
maintenance, see “Parts and tools” on page 291.
Utmost care should be taken when working on your vehicle to
prevent accidental injury. Here are a few precautions that you
should be especially careful to observe:
CAUTION
 When the engine is running, keep hands, clothing,
and tools away from the moving fan and engine drive
belt. (Removing rings, watches, and ties is
advisable.)
 Right after driving, the engine compartment the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. will be hot. So be
careful not to touch them. Oil and other fluids may
also be hot.
 Do not smoke, cause sparks or allow open flames
around fuel or the battery. Their fumes are
flammable.
 Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or
other solid supports.
 Be sure that the ignition is off if you work near the
electric cooling fans or radiator grille. With the
ignition on, the electric cooling fans will
automatically start to run if the engine coolant
temperature is high and/or the air conditioning is on.
 Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
