■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends that maintenance service operations as well as ot her inspections and repairs be carried out by authorized Lexus dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an authorized Lexus dealer or repairer, who will use genuine Lexus parts in repairing any difficulties youmay encounter. There can also be advantages in utilizing authorized Lexus dealers or
repairers for non-warranty repa irs and services, as members of the Lexus network will be able to expertly assist you with any difficulties you may encounter.

perform all of the scheduled maintenance on your vehicle reliably and economically due to their experience with Lexus vehicles.

●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air conditioning sys-
tem after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor,vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal ( P. 666)
If you notice any of these clues, take your vehicle to any authorized Lexus dealer or repairer, or another duly qualified and equipp ed professional as soon as possible. Your vehicle may need adjustment or repair.

WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe the following precautions.
■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-
sive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur- faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
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. ( P. 607)
■Safety glasses
Wear safety glasses to prevent flying or fa lling material, fluid spray, etc., from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high.If the reservoir needs frequent refillin g, it may indicate a serious problem.
