Instrument cluster
■Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help improve fuel
efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when vehicle
operation and driving conditions are the same.
■Outside temperature display
●In the following situations, the correct outside temperature may not be displayed, or the
display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has changed suddenly (at the entrance/exit of agarage, tunnel, etc.)
●When “--” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to your Lexus dealer.
■Customization
Settings (e.g. on/off operation of the ECO lamp) can be changed.
(Customizable features: →P. 5 9 1 )
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer 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. 565)

146
CT200h_OM_OM76174U_(U)4-1. Before driving
WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
●The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the hybrid system. Turning the hybrid system off
while driving will not cause loss of steering or braking control, however, power assist
to the steering will be lost. This will make it more difficult to steer smoothly, so you
should pull over and stop the vehicle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the vehicle in
the normal way: → P. 5 2 1
●Use engine braking (shift position B instea d of shift position D) to maintain a safe
speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effective-
ness. ( →P. 1 6 3 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or not before driving at such speeds.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your
ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly,
steering control may be affected.

Observe the following precautions.
Failure to do so may result in death or serious injury.
■When shifting the shift position
●Do not let the vehicle roll backward while a forward driving position is selected, or roll
forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift position to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift position to N while the vehicle is moving will disengage the hybrid
system. Engine braking is not available with the hybrid system disengaged.
●Be careful not to change the shift position with the accelerator pedal depressed.
Changing the shift position to any positions other than P or N may lead to unex-
pected rapid acceleration of the vehicle that may cause an accident and result in
death or serious injury.
After changing the shift position, make sure to confirm the current shift position dis-
played on the shift position indicator inside the meter.
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the shift position is any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while stopped with the “READY” indicator is illuminated, and apply
the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, alwa ys depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as
this may restrain driving torque.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift position to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the follo wing situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 5 4 7 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission, etc.
●Lubricant condition for the bearings and susp ension joints (where possible), and the
function of all joints, bearings, etc.
If the shift control system is damaged by floodin g, it may not be possible to shift the shift
position to P, or from P to other positions. When the shift position cannot be changed
from P to any other position, the front wheels will lock, and you will be unable to tow the
vehicle with the front wheels on the ground, as the front wheels may be locked. In this
case, transport the vehicle with both front wheels or all four wheels lifted.

Power (ignition) switch
Check that the parking brake is set.
Firmly depress the brake pedal.
Check that the power switch indicator turns green. If the indicator does not turn
green, the hybrid system cannot be started.
When the shift position is N, the hybrid system cannot start. Shift the shift position to P
when starting the hybrid system. (
→P. 1 6 3 )
Press the power switch.
Continue depressing the brake pedal
until the hybrid system is completely
started.
The hybrid system can be started from
any power switch mode.
Check that the “READY” indicator is illuminated.
If the “READY” indicator changes from a flashing light to a solid light and the buzzer
sounds, the hybrid system is starting normally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if the engine is stopped.
(The gasoline engine starts or stops automatically in accordance with the state of the
vehicle.)

■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply engine brak-
ing.
• When the vehicle is driven at high speeds, compared to ordinary gasoline-fueled vehi- cles, 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 contin uously in the B position, fuel efficiency will become low. Usu-
ally, select the D position.
■When driving with cruise control or dynamic radar cruise control activated
Even if switching the driving mode to sport mo de with the intent of enabling engine brak-
ing, engine braking will not activate because cruise control or dynamic radar cruise con-
trol 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. 5 6 1 )
■After recharging/reconnecting the 12-volt battery

■Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features: →P. 5 9 1 )
WA R N I N G
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in engine braking may cause th e vehicle to spin or skid, resulting in an
accident.
■For the shift lever
Do not remove the shift lever knob or use anything but a genuine Lexus shift lever
knob. Also, do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing unexpected
accidents to occur when the vehicle is in motion.
■P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for example, directly
before stopping the vehicle), the vehicle may stop suddenly when the shift position
switches to P, which could lead to an accident.

CT200h_OM_OM76174U_(U)4-6. Driving tips
◆Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check
traffic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆Highway driving
Control and maintain the vehicle at a cons tant speed. Before stopping at a toll
booth or similar, allow plenty of time to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out until it
and the interior of the vehicle are warm, it will consume fuel. Fuel consumption
can be improved by avoiding overuse of the heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on dry roads
can lead to poor fuel economy. Use tires that are appropriate for the season.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeatedly warm up, which can lead to excess
fuel consumption.
