Power heater
Power heater can be operated when
The engine is running.
Normal characteristics of power heater operation
The following cases do not indicate a malfunction.
When the power heater is turned on or off, some white smoke and a
slight odor may be emitted from the power heater exhaust that is located
under the floor.
When the power heater is being used under extremely cold conditions,
vapor may be visible from its exhaust.
When the power heater is turned off, you may hear a sound in the engine
compartment for about 2 minutes until the power heater turns off com-
pletely.
After the heater is off
We recommend not restarting the heater for 10 minutes after you turn it off.
Otherwise, a noise may be heard as the heater ignites.
When refueling your vehicle
The heater must be off.
This feature is used to keep the cab warm in cold conditions.

CAUTION
To prevent burns or damage on your vehicle
NOTICE
To prevent damage to your vehicle
Do not turn the heater on and off repeatedly in 5 minute intervals as this
can shorten the life of the heater components. If the engine must be turned
on and off repeatedly within short intervals (such as when the vehicle is
being used for delivery purposes), turn the heater off.
Do not modify or open the heater without consulting any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional. This may cause a heater malfunction or even a fire.
Be careful not to splash water or spill liquid directly on the heater or on
the heater fuel pump. This may cause the heater to malfunction.
Keep the intake and exhaust pipes of the heater free from water, snow, ice,
mud, etc. If the pipes become clogged, this can cause the heater to mal-
function.
If you notice anything unusual, such as a fluid leak, smoke or poor opera-
tion, turn off the heater and have your vehicle checked by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
Do not touch the heater or its exhaust
pipe as they are hot. You may burn
yourself.
Keep flammable items such as fuel
away from the heater and its exhaust
pipe, as this may cause a fire.

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.

Engine oil consumption
The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
A new engine consumes more oil.
When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level
accurately.
Oil consumption: Max. 1.0 L per 1,000 km (1.1 qt./600 miles, 0.9 Imp.
qt./600 miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every
1000 km (600 miles), contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
After changing the engine oil (IS220d and IS200d)
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer (P. 171) when the engine is
running.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE
START STOP” switch to IGNITION ON mode (but do not start the
engine because otherwise the reset mode will be cancelled). Con-
tinue to press and hold the button until the trip meter displays
“000000”.
