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 the 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 pedalscomfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm)
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 recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

Installing child restraints
Follow the child restraint system manufacturer's instructions. Firmly
secure child restraints to the rear seats using the LATCH anchors or a seat
belt. Attach the top tether strap when installing a child restraint.
The lap/shoulder belt can be used if your child restraint system is not com-
patible with the LATCH (Lower Anchor s and Tethers for Children) system.
Child restraint LATCH anchors
LATCH anchors are provided
for the outside rear seats. (But-
tons displaying the location of
the anchors are attached to the
seats.)
Seat belts equipped with a child
restraint locking mechanism
(ALR/ELR belts except driver’s
seat belt) (→P. 6 5 )
Anchor bracket (for top tether
strap)
Anchor brackets are provided
for all rear seats.

Maintenance and care
IS350/250_U
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not apply water. Excellent
results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→ P. 9 8 )
Electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or severe injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver's view and leading to an accident, resulting in
death or serious injury.

CAUTION
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts
contain lead and lead compounds. Observe the following precautions when han-
dling the battery.
●When working with the battery, always wear safety glasses and take care not to
allow any battery fluids (acid) to come into contact with skin, clothing or the vehi-
cle body.
●Do not lean over the battery.
●In the event that battery fluid comes into contact with the skin or eyes, immedi-
ately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can be
received.
●Always wash your hands after handling the battery support, terminals, and other
battery-related parts.
●Do not allow children near the battery.
NOTICE
■To prevent damaging the vehicle
Do not pull- or push-start the vehicle, because the three-way catalytic converter
may overheat and become a fire hazard.
■When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fan or any
of the belts when connecting or disconnecting them.
