4-1. Before driving
CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move
the shift lever or depress the accelerator pedal, this could cause an accident or fire
due to engine 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 brake booster (gasoline vehicles) or brake actuator (hybrid vehicles) does
not operate, do not follow other vehicles closely and avoid hills 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. Have your brakes
fixed immediately.
●Gasoline vehicles only: Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●Gasoline vehicles: The brake system consists of 2 individual hydraulic systems; if
one of the systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. Have your brakes fixed immediately.
Hybrid vehicles: The brake system consists of 2 or more individual hydraulic sys-
tems; if one of the systems fails, the other(s) will still operate. In this case, the brake
pedal should be depressed more firmly than usual and the braking distance will
increase. Have your brakes fixed immediately.

4-6. Driving tips
Hybrid vehicle driving tips (hybrid vehicles)
When using Eco drive mode, the torque corresponding to the accelerator
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 economy.
(→P. 311)
The Eco-friendly driving is possible by keeping the indicate of Hybrid Sys-
tem Indicator within Eco area. ( →P. 1 0 0 )
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel consumption. Check traffic reports before leav-
ing 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.
For economical and ecological drivin g, pay attention to the following

■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the micro dust and pollen filter is turned off.
■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning sy stem is controlled as follows to priori-
tize 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 performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
■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 conditioning system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning 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.
