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
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-

Maintenance and care
Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as that
already in the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following
situations, oil consumption may increase, and engine oil may need to be refilled
in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle or
after replacing the engine
If low quality oil or oil of an inappropriate viscosity is used
When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
When leaving the engine idling for a long time, or when driving frequently
through heavy traffic

Used engine oil
Used engine oil contains potentially harmful contaminants which may cause
skin disorders such as inflammation and skin cancer, so care should be taken
to avoid prolonged and repeated contact. To remove used engine oil from
your skin, wash thoroughly with soap and water.

fied and equipped professional, service station or auto parts store for informa-
tion concerning recycling or disposal.
Do not leave used engine oil within the reach of children.

Maintenance and care
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the hybrid system is cold.
Engine coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line. (P. 628)
Power control unit coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line. (P. 628)
Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35C [-31F])
For more details about coolant, contact any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for leaks
in the cooling system.

Check the radiator and condenser and clear away any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their
condition, have your vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the cap
is removed, causing serious injuries, such as burns.
NOTICE
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion pro-
tection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
Radiator and condenser
WA R N I N G
When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause serious
injuries, such as burns.
When the electric cooling fans are operating
Do not touch the engine compartment.
The electric cooling fans may keep rotating for about 3 minutes even after 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. Be sure the power switch is off when working near the electric cooling
fans or radiator grille.
