Child seat belt usage
The seat belts of your vehicle are principally designed for persons of adult
size.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle's seat belt. (P. 121)
When the child becomes large enough to properly wear the vehicle's seat
belt, follow the instructions on P. 74 regarding seat belt usage.
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will acti-
vate for the first collision, but will not activate for the second or subsequent
collisions.
Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for seat belt replacement or installation.
CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
Wearing a seat belt
Ensure that all passengers wear a seat belt.
Always wear a seat belt properly.
Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
Lexus recommends that children be seated in the rear seat and always use
a seat belt and/or an appropriate child restraint system.
Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
Do not wear the shoulder belt under your arm.
Always wear your seat belt low and snug across your hips.

Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for further information when replacing tires or

Selecting tire chains
Tire chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire size.

When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed
suitable to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to P (automatic
transmission) or 1 or R (manual transmission) without setting

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of han-
dling control.
Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diame-
ter, rim width, and inset
*.
Replacement wheels are available at any authorized Lexus
dealer or repairer, or another duly qualified and equipped pro-
fessional.
*: Conventionally referred to as “offset”.
Lexus does not recommend using:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Aluminum wheel precautions
Use only Lexus wheel nuts and wrenches designed for use
with your aluminum wheels.
When rotating, repairing or changing your tires, check that
the wheel nuts are still tight after driving 1600 km (1000
miles).
Be careful not to damage the aluminum wheels when using
tire chains.

CAUTION
When replacing wheels
Do not use wheels that are a different size from those recommended in the

IS250/220d/200d_EE
Installing the spare tire
Remove any dirt or foreign
matter from the wheel contact
surface.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is
in motion, and the tire may
come off the vehicle.
Install the spare tire and loosely tighten each wheel nut by
hand by approximately the same amount.
Vehicles with a compact spare tire
Tighten the nuts until the
tapered portion comes into
loose contact with the disc
wheel seat.
Vehicles with a full-size spare tire
Turn the nuts until the washers
come into contact with the
wheel.

Emergency tire puncture repair kit
The sealant has a limited lifespan. The expiry date is marked on the bot-
tle. The sealant should be replaced before the expiry date. Contact any
authorized Lexus dealer, tire dealer or repairer, or another duly qualified
and equipped professional for replacement.
The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant in the bottle
and other parts of the kit have been used and need to be replaced, contact
any authorized Lexus dealer, tire dealer or repairer, or another duly qual-
ified and equipped professional.
The sealant can be used when the outside temperature is from -30C (-
22F) to 60C (140F).
The kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that are a different size
than the original ones, or for any other purpose.
If the sealant gets on your clothes, it may stain.
If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immediately wipe
away the sealant with a wet cloth.
During operation of the kit, a loud operation noise is produced. This does
not indicate a malfunction.
