◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) off when it is
not needed. Doing so can help reduce excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on th e
air conditioning system and reduc e electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the heated steering w heel (if equipped) and seat heat-
ers is effective. ( P. 5 2 6 )
● Using the Remote Air Conditioning System ( P. 522) while the
charging cable is connected to the vehicle can reduce electrici ty
consumption immediately after st arting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode a nd
setting “Climate Prep” to “On” c an reduce electricity consumption
immediately after starting off by operating air conditioning be fore
charging is completed. ( P. 157)

◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If t here is
improper tire inflation pressur e in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead t o increased fuel and electricity consumptio n.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing 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,
warming up is not necessary.

Winter driving tips
●Use fluids that are appropriate t o the prevailing outside tempera-
tures. • Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspect the condition of the 12-volt bat-
tery.
● 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 cha ins match
the size of the tires.
Perform the following accordi ng to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to p revent 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 ic e or snow that may have accu-
mulated 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 vehicle in winter. Always drive the vehicle in a ma n-
ner appropriate to the prevailing weather conditions.

■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Si nce summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in sno w and to
be adequate for driving in most winter conditions as well as fo r use
year-round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season tires fall short in acceleration and handling performanc e com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as t he originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construct ion. Do not install studded tires without
first checking local regulations for possible restrictions. Sno w tires
should be install ed on all wheels. ( P. 495)
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
