■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)

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.

Driving
WA R N I N G
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.
