In the following cases, contact your Lexus dealer as soon as
possible:
The front of the vehicle (shaded in the illustration) was
involved in an accident that was not severe enough to cause
the front seat belt pretensioners to operate.
 Either front seat belt pretensioner assembly or surrounding
area is scratched, cracked, or otherwise damaged.
SRS AIRBAGS
The SRS (Supplemental Restraint System) airbags are
designed to provide further protection for the driver, front
passenger and rear outside passengers in addition to the
primary safety protection provided by the seat belts.
SRS front airbags
In response to a severe fr ontal impact, the SRS front
airbags work together with the seat belts to help reduce
injury by inflating. The SRS front airbags help to reduce
injuries mainly to the driver’s or front passenger’s head or
chest caused by directly hitting the steering wheel or
dashboard.
The front passenger airbag is activated even with no
passenger in the front seat.

COMFORT ADJUSTMENT
11 6Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the
driver and front passenger when the SRS front
airbags are inflated.
Be sure to wear your seat belt properly.
CAUTION
The driver or front passenger who is too close to the
steering wheel or dashboard during airbag deployment
can be killed or seriously injured. Lexus strongly
recommends that:
 The driver sit as far back as possible from the
steering wheel while still maintaining control of the
vehicle.
 The front passenger sit as far back as possible from
the dashboard.
 All vehicle occupants be properly restrained using
the available seat belts.
SRS side airbags
In response to a severe side impact, the SRS side airbags
for the driver or front passenger work together with the
seat belts to help reduce injury by inflating. The SRS side
airbags help to reduce injuries mainly to the driver’s or
front passenger’s chest.
The SRS side airbag on the passenger seat is activated even
with no passenger in the front seat.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver and front passenger when the SRS side
airbags are inflated.
Be sure to wear your seat belt properly.

COMFORT ADJUSTMENT
11 7
CAUTION
SRS side airbags inflate with considerable force. To
avoid potential death or serious injury when they inflate,
the driver and front passenger must:
 Wear their seat belts properly.
 Remain properly seated with their back upright and
against the seat at all times.
SRS curtain shield airbags for front and rear outside
occupants
In response to a severe side impact, the SRS curtain
shield airbag on either side works together with the seat
belts by inflating. The SRS curtain shield airbags help to
reduce injuries mainly to the driver’s head, front
passenger’s head and rear outside passenger’s head.
The SRS curtain shield airbag is activated even with no
passenger in the front seat or rear seat.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver and front passenger when the SRS
curtain shield airbags are inflated.
Be sure to wear your seat belt properly.

COMFORT ADJUSTMENT
11 8
CAUTION
The SRS curtain shield airbags inflate with considerable
force. To avoid potential death or serious injury when
they inflate, the driver, front passenger and rear outside
passenger must:
 Wear their seat belts properly.
 Remain properly seated with their back upright and
against the seat at all times.
The indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS airbags are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
“Service reminder indicators and warning buzzers” on page 48
for instructions.)

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 .

STARTING AND DRIVING
220
To allow proper operation of your vehicle’s
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the trunk lid closed. Have the
cause immediately located and corrected.
BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, seat cushion angle,
seat cushion height, head restraint height and steering wheel
angle.
3. Vehicles with power adjustable pedals—Adjust the position
of the accelerator and brake pedals.
4. Adjust the inside and outside rear view mirrors.
5. Lock all doors.
6. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to “ON”, and check the fuel
gauge to see that you have sufficient fuel.
IGNITION SWITCH WITH STEERING
LOCK
“START” Starter motor on. The key will return to the
“ON” position when released.
For starting tips, see page 222.

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.
