CT200h_OM_OM76102E_(EE)
When the outside temperature is low
The dehumidification function may not operate even when “A/C” is pressed or
“A/C” is selected.
Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. (P. 658)
Ventilation and air conditioning odors
To let fresh air in, set the air conditioning system to the outside air mode.
During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
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.
Air conditioning filter
P. 527
Customization
Settings (e.g. A/C automatic mode switch operation) can be changed.
(Customizable features: P. 650)

When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
When cleaning the windshield (vehicles with rain-sensing windshield wipers)
When the upper part of the windshield where the raindrop sensor is located is
touched by hand
When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into the
raindrop sensor
Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.

4887-2. Maintenance
CT200h_OM_OM76102E_(EE)
Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Lexus dealers or repairers or other duly qual-
ified and equipped professionals. For repairs and services covered by your war-
ranty, 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 profes-
sional will perform all of the scheduled maintenance on your vehicle reliably and
economically due to their experience with Lexus vehicles.
Does your vehicle need repairs?
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 condition-
ing system 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 imme-
diately.)
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. 570, 583)
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 possi-
ble. Your vehicle may need adjustment or repair.

Maintenance and care
WA R N I N G
The engine compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or seri-
ous injury, observe the following precautions.
When working on the engine compartment
Make sure that the indicator on the power switch and the “READY” indicator
are both off.
Keep hands, clothing and tools away from the moving fan.
Be careful not to touch the engine, power control unit, radiator, exhaust mani-
fold, 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. Fuel fumes are
flammable.
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, consult
a doctor.
When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is
high. (P. 502)
Safety glasses
Wear safety glasses to prevent flying or falling 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 refilling, it may indicate a serious problem.

Maintenance and care
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
Checking the engine oil
Park the vehicle on level ground. After warming up the engine and
turning off the hybrid system, wait more than 5 minutes for the oil to
drain back into the bottom of the engine.
Holding a rag under the end,
pull the dipstick out.
Wipe the dipstick clean.
Flat dipstick: Reinsert the dipstick fully.
Non-flat dipstick: Reinsert the
dipstick fully with its protrud-
ing areas ( in the illustra-
tion) pointing towards engine.
