Press the “ON•OFF” button to
activate the cruise control.
Radar cruise control indicator will
come on and a message will be shown
on the multi-information display.
Press the button again to deactivate
the cruise control.
Accelerate or decelerate the

While the vehicle is in vehicle-to-vehi-
cle distance control mode, if the lever
is released when vehicle speed is less
than 30 mph (50 km/h) and a vehicle
ahead can be detected, the vehicle
will start following the vehicle ahead at
a set speed of 30 mph (50 km/h).

■Temporary cancelation of the LKA system functions
If any of the following occurs, the LKA system functions will be temporarily canceled.
The functions will resume after the necessary operating conditions have returned.
●The steering wheel is turned as far as necessary to cause the vehicle to change
lanes.
●When the system detects no-handed driving. (The lane keeping assist function will
be temporarily canceled, but the lane departure warning function will continue.)
●The turn signal lever is operated.
●The vehicle speed deviates from the operating range of the LKA system functions.
(The buzzer will beep twice when the lane keeping assist function is being can-
celed.)
●When the lane lines cannot be recognized while driving.
●When the wiper switch is in the high speed position or is set to “AUTO” mode with
the wipers operating at high speed. (The la ne keeping assist function will be tempo-
rarily canceled, but the lane departure warning function will continue.)
●If the vehicle crosses a line for approximately half a minute or more. (The lane keep-
ing assist function will be temporarily canceled, but the lane departure warning
function will continue.)
●When the lane departure warning function is activated.
The lane departure warning function will not operate again for several seconds
after it has been activated, even if the vehicle leaves the lane again.
■The lane departure warning
It may be difficult to feel the sensory warning depending on the road conditions.
■No-handed driving warning
If the steering wheel is not operated for approximately 15 seconds on a straight road
or approximately 5 seconds on a curve, the buzzer will beep twice, indicators on the
multi-information display will flash, and the lane keeping assist function will be tem-
porarily canceled. If you drive the vehicle with your hands lightly touching the steer-
ing wheel, this may also be detected as no-handed driving.

Eco drive mode
Use Eco drive mode to help achieve low fuel consumption during trips
that involve frequent accelerating.
When in comfort mode and the driving mode select switch is turned to the left,
the “ECO MODE” indicator comes on in the multi-information display.
Also, the driving mo de is automati-
cally displayed on the “Side Display”.

■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air
conditioning system to enhance fuel efficiency ( P. 336). To improve air condition-
ing performance, adjust the fan sp eed or turn off Eco drive mode.
■Sport mode automatic deactivation
Sport mode is automatically deactivated if th e power switch is turned off after driving
in sport mode.

4-6. Driving tips
■Using Eco drive mode
When using Eco drive mode, the torque corresponding to the acceler-
ator pedal depression amount can be generated more smoothly than it
is in normal conditions. In addition, the operatio n of the air conditioning
system (heating/cooling) will be mini mized, improving the fuel econ-
omy. ( P. 283)
■Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of Hybrid
System Indicator within Eco area. ( P. 103)
■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 decelerati on, 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 for-
ward 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 acceler-
ator and gently apply the brakes. A greater amount of electrical energy
can be retained when slowing down.
Hybrid vehicle driving tips
For economical and ecological drivin g, pay attention to the following

Select: Move the knob in the
desired direction.
Enter: Press the knob.
■Screen display during low temperatures
When the ambient temperature is extremely low, screen response may be delayed
even if the Remote Touch is operated.

CAUTION
■When using the Remote Touch
●Do not allow fingers, fingernails or hair to become caught in the Remote Touch as
this may cause an injury.
●Be careful when touching the Remote Touch in extreme temperatures as it may
become very hot or cold due to the temperature inside the vehicle.
NOTICE
■To prevent damage to the Remote Touch
●Do not allow the Remote Touch to come into contact with food, liquid, stickers or
lit cigarettes as doing so may cause it to change color, emit a strange odor or stop
functioning.
●Do not subject the Remote Touch to excessive pressure or strong impact as the
knob may bend or break off.
●Do not allow coins, contact lenses or other such items to become caught in the
Remote Touch as this may cau se it to stop functioning.
●Items of clothing may rip if they become caught on the Remote Touch knob.
●If your hand or any object is on the Remote Touch knob when the power switch is
turned to ACCESSORY mode, the Remote Touch knob may not operate prop-
erly.

3485-3. Using the air conditioning system and defogger
LS600hL_U(OM50E41U)
■Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to prioritize
fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/cooling
capacity
●Fan speed restricted when automatic mode is selected
To improve air conditioning performanc e, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode
The air conditioning control of Eco drive mode can be changed to the same setting
as that used in normal drive mode. (Customizable features P. 564)
■Using the automatic mode
Fan speed is adjusted automatically in a ccordance with the temperature setting and
ambient conditions. As a result, the following may occur:
●Immediately after the “AUTO” switch is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around th e upper body when the heater is on.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunn els or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicl e interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

3505-3. Using the air conditioning system and defogger
LS600hL_U(OM50E41U)
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and
accumulate in the air condit ioning system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditio ning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immedi- ately after the air conditioning system is started in automatic mode.
■Air conditioning filter
 P. 4 6 9
■Customization
Settings (e.g. exhaust gas sensor se nsitivity, etc.) can be changed.
(Customizable features P. 5 6 4 )
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outs ide air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the hybrid
system is off.
