been pressed
TRC cannot be operated. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid system is
started, just after the vehicle begins to move, if the brake pedal is depressed
forcefully or repeatedly, or 1-2 minutes after the hybrid system is stopped. This
sound does not indicate that a malfunction has occurred in any of these systems.
Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering input over an extended period of time.
The steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the hybrid system off. The
EPS system should return to normal within 10 minutes.
Automatic reactivation of TRC system
After turning the TRC system off, the system will be automatically re-enabled in
the following situations:
When the power switch is turned off
The TRC will turn on when vehicle speed increases
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge from
the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.
The brake pedal is released.
The system judges from the vehicle deceleration that is not a sudden braking
operation.

Hybrid vehicle driving tips
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelera-
tor 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, improving the fuel econ-
omy. (P. 267)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicator needle of
Hybrid System Indicator within Eco area. (P. 107)
Shift lever operation
Shift the shift position to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift position to P when parking. When
using the N position, there is no positive effect on fuel consumption. In
the N position, the gasoline engine operates but electricity cannot be
generated. Also, when using the air conditioning system, etc., the
hybrid battery (traction battery) power is consumed.
Accelerator pedal/brake pedal operation
Drive your vehicle smoothly. Avoid abrupt acceleration and deceler-
ation. Gradual acceleration and deceleration will make more effec-
tive use of the electric motor (traction motor) without having to use
gasoline engine power.
Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the acceler-
ator pedal slightly released.
When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be retained when slowing
down.
For economical and ecological driving, pay attention to the following
points:
2824-6. Driving tips
CT200h_OM_OM76102E_(EE)
Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel economy. Check traffic reports before leav-
ing and avoid delays as much as possible. When driving in a traffic
jam, gently release the brake pedal to allow the vehicle to move for-
ward slightly while avoiding overuse of the accelerator pedal. Doing so
can help control excessive gasoline consumption.
Highway driving
Control and maintain the vehicle at a constant 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 condition-
ing 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
inflation 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 distances will cause the engine to repeatedly warm up,
which can lead to excess fuel consumption.

Winter driving tips
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect the condition of the 12-volt battery.
Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match the size
of the tires.
Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away the
water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the
windshield.
Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or
on the brakes.
Remove any snow or mud from the bottom of your shoes before get-
ting in the vehicle.
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.

Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or seri-
ous injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit specified
for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and
may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden acceleration, abrupt steering, sudden braking and shifting oper-
ations that cause sudden engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle control
is maintained.
When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move unex-
pectedly, possibly resulting in an accident.
NOTICE
Repairing or replacing snow tires (vehicles with the tire pressure warning sys-
tem)
Request repairs or replacement of snow tires from any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional or legitimate
tire retailers.
This is because the removal and attachment of snow tires affects the operation
of the tire pressure warning valves and transmitters.
Fitting tire chains (vehicles with the tire pressure warning system)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
