Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improv-
ing the fuel economy.
(P. 209)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. (P. 222)
When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic
reports before leaving and avoid delays as much as possible. When
encountering a delay, gently release the brake pedal to allow the
vehicle to move forward slightly while avoiding overuse of the
accelerator pedal. Doing so can help control excessive gasoline
consumption.
Highway driving
Control your speed and keep at a constant speed. Also, before stop-
ping at a toll booth or similar, allow plenty of time to release the
ldllhbkA fli

Starting off on a uphill
Firmly set the parking brake with the brake pedal
depressed, and then shift the shift position to D.
Release the brake pedal and gently depress the accelerator
pedal.
Release the parking brake.
When starting off on a uphill
The hill-start assist control is available. (P. 296)
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be
especially slippery.
Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.

CAUTION
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional
immediately.
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.
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, but the power assist to these systems will be lost. This will make
it more difficult to steer and brake, so you should pull over and stop the
vehicle as soon as it is safe to do so. However, in the event of an emer-
gency, such as if it becomes impossible to stop the vehicle in the normal
way: P. 6 4 6
Use engine braking (shift position B instead of shift position D) to main-
tain a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 207)

CAUTION
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 that can cause accidents,
resulting in death or serious injury.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
Abrupt changes from shift position D to B and rapid changes in the engine
speed could cause the vehicle to skid, resulting in an accident.
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 functioning properly. If the brakes on only one side are
wet and not functioning properly, steering control may be affected, result-
ing in an accident.
When changing the shift position
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 cause the
vehicle to accelerate abruptly, causing an accident and resulting in death or
serious injury.
After changing the shift position, make sure to confirm the current shift
position displayed on the shift position indicator inside the meter.

CAUTION
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked
in a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
When braking
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
If the electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns that require
braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will
increase.
The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the others will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. If this happens, do not continue to drive the vehicle. If the brake
system warning light (red indicator) comes on together with the buzzer
sound while driving, immediately stop the vehicle in a safe place and con-
tact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.

Cruise control can be set when
The shift position is in D.
Vehicle speed is above approximately 40 km/h (25 mph).
Accelerating after setting the vehicle speed
The vehicle can be accelerated normally. After acceleration, the set
speed resumes.
Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
Canceling and resuming the constant speed control
Pulling the lever toward
you cancels the constant
speed control.
The speed setting is also can-
celed when the brakes are
applied.

When driving
CT200h_OM_OM76067E_(EE)Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-
to-vehicle distance can also be set by operating the vehicle-to-vehicle
distance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automat-
ically decelerates your vehicle. When a greater reduction in vehicle
speed is necessary, the system applies the brakes. A warning tone
warns you when the system cannot decelerate sufficiently to prevent
your vehicle from closing in on the vehicle ahead.
Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes
in the speed of the vehicle ahead in order to maintain the vehicle-to-
vehicle distance set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than
the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient
automatic deceleration via the cruise control is not possible, the
display will flash and the buzzer will sound to alert the driver. An
example of this would be if another driver cuts in front of you
while you are following a vehicle. Apply the brakes to ensure an
appropriate vehicle-to-vehicle distance.
Warnings may not occur when
In the following instances, there is a possibility that the warn-
ings will not occur:
When the speed of the vehicle ahead matches or exceeds your
vehicle speed
When the vehicle ahead is traveling at an extremely slow
speed
Immediately after the cruise control speed was set
At the instant the accelerator is applied

CAUTION
Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your
vehicle and vehicles ahead by applying the brakes etc.
Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and
a designated vehicle traveling ahead. It is not a mechanism that allows
careless or inattentive driving, and it is not a system that can assist the
driver in low-visibility conditions. It is still necessary for driver to pay
close attention to the vehicle’s surroundings.
Assisting the driver to judge proper following distance
The dynamic radar cruise control determines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is appropriate or not. It is not capable of making any other type of
judgement. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of danger in
any given situation.
Assisting the driver to operate the vehicle
The dynamic radar cruise control has no capability to prevent or avoid a
collision with a vehicle traveling ahead. Therefore, if there is ever any
danger, the driver must take immediate and direct control of the vehicle
and act appropriately in order to ensure the safety of all involved.
