■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driving
as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel andbattery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and corro-

water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the electric cooling fans may auto-matically start to run if the air conditioning is on and/or the coolant temperature is high.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drivetrain as well as dangerous han-
dling characteristics, which may lead to an acc ident resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns. Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Lexus.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle. Do not use tires if you do not know how they were used previously.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a compact spare
tire installed.
●Vehicles with an emergency tire puncture repa ir kit: Do not tow anything if a tire that has been repaired using the emergency tire puncture repair kit is installed. The load
on the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning re set switch without first adjusting the tire
inflation pressure to the specified level. Ot herwise, the tire pressure warning light may not come on even if the tire inflation pressu re is low, or it may come on when the tire inflation pressure is actually normal.
■Caution regarding interference with electronic devices (vehicles with the tire pres-sure warning system featuring a tire inflation pressure display function)
●Users of any electrical medical device other than implantable cardiac pacemakers,cardiac resynchronization therapy-pacemakers or implantable cardioverterdefibrillators should consult the manufacturer of the device for information about its
operation under the influence of radio waves. Radio waves could have unexpected effects on the operation of such medicaldevices.
●People with implantable cardiac pacemakers,cardiac resynchronization therapy-pacemak-ers or implantable cardioverter defibrillators
should not come within 450 mm (17.7 in.) of the tire pressure warning system initiators.The radio waves may affect the operation of

Vehicles with a spare tire
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressureimmediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust- ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change itwith the spare tire and have the flat tire repaired by the nearest authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose control of the steering wheel or the brakes.
Vehicles with an emergency tire puncture repair kit
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressureimmediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust- ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, repair theflat tire by using emergency tire puncture repair kit.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose control of the steering wheel or the brakes.
