prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.

When working on the engine compartment ●
Keep hands, clothing and tools away from the moving fans and engine drive belt.●
Be careful not to touch the engine, radiator , exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.●
Do not leave anything that may burn easi ly, 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
and battery fumes are flammable.●

Maintenance and care ■
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following: ●
Reduced fuel efficiency●
Reduced driving comfort and tire life●
Reduced safety●
Damage to the drive train
If a tire needs frequent inflating, have it checked by your Lexus dealer.■
Instructions for checking tire pressure
When checking tire inflation pressure, observe the following: ●
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading.●
Always use a tire pressure gauge.
The appearance of the tire can be mislea ding. In addition, tire inflation pressure
that is even just a few pounds off can degrade ride and handling.●
Do not reduce tire inflation pressure after driving. It is normal for tire inflation
pressure to be higher after driving.●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
