Where to go for service?
In order to maintain your vehicle in the highest possible condition, Lexus
recommends that all repairs and service operations be carried out by autho-
rized 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 you may encounter. There can also be advantages
in utilizing authorized Lexus dealers or repairers for non-warranty repairs
and services, as members of the Lexus network will be able to expertly
assist you with any difficulties you may encounter.
Your Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional service department will perform all of the scheduled maintenance
on your vehicle - reliably and economically due to their experience with
Lexus vehicles.
Does your vehicle need repair?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
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 after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monox-
ide 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 driving 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
If you notice any of these clues, take your vehicle to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional, as
soon as possible. Your vehicle may need adjustment or repair.

4-3. Do-it-yourself maintenance
IS250/220d/200d_EE
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. 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 or 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.
Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
When working near the electric cooling fan or radiator grille
Be sure the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the
electric cooling fan may automatically start to run if the air conditioning is
on and/or the coolant temperature is high. (P. 415)
CAUTION
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in the eyes.

NOTICE
If you remove the air cleaner
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air. Also, a backfire could cause a fire in the engine compart-
ment.
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 refilling, it may indicate a serious problem.
