When driving
CT200h_OM_OM76067E_(EE)
About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
• When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
When driving with cruise control or dynamic radar cruise control activated
Even if switching the driving mode to sport mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
dynamic radar cruise control will not be canceled.
Automatically P position selection function
When the shift position is in a position other than P, pressing the “POWER”
switch with the vehicle stopped completely will cause the shift position to
change to P automatically, and then the “POWER” switch will turn off.
If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-
volt battery in this situation. (P. 633)
Sport mode automatic deactivation
Sport mode is automatically deactivated if the “POWER” switch is turned
off after driving in sport mode.
After recharging/reconnecting the 12-volt battery
P. 5 1 1
Customization
Settings (e.g. Reverse warning buzzer) can be changed.

Customization
Settings (e.g. on/off operation of the ECO lamp) can be changed.
(Customizable features P. 667)
NOTICE
To prevent damage to the engine and its components
Vehicles with tachometer: Do not let the indicator needle of the tachome-
ter enter the red zone, which indicates the maximum engine speed.
The engine may be overheating if the high coolant temperature warning
light comes on or flashes. In this case, immediately stop the vehicle in a
safe place, and check the engine after it has cooled completely. (P. 6 3 9 )

Maintenance and care
CT200h_OM_OM76067E_(EE)
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
conditioning system 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 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
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.
CAUTION
If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and
possible serious injury or death.
Handling of the 12-volt battery
12-volt battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands after
handling. (P. 508)

CT200h_OM_OM76067E_(EE)
Engine oil
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 illustration)
pointing towards engine.
Holding a rag under the end, pull the dipstick out and check
the oil level.

CT200h_OM_OM76067E_(EE)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.

Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality eth-
ylene 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%
deionized 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 reser-
voir 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.
CAUTION
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.
