■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
→P. 4 8 6
■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.

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 imme-
diately 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 accumulated 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 getting in the
vehicle.
Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
