Plug-in hybrid system
The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the we ather,
the outside temperature, usage con ditions of electrical components
and the number o f occupants.
The distance that can be driven in EV mode can be extended if t he fol-
lowing is performed:
● Maintain a safe distance from t he vehicle in front and avoid un nec-
essary acceleration and deceleration
● Accelerate and decelerate the v ehicle as smoothly as possible
● Drive at moderate speeds as much as possible and maintain a con -
stant speed
● Set the air conditioning to a moderate temperature and turn the “A/C”
switch (
*1 • *2) off when it is not needed
● Use tires of the specified size and maintain the specified tire pres-
sure
● Use the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will in crease substantially when drivin g on a
highway in EV mode.
● Do not add unnecessary w eight to the vehicle
*1: Vehicles with 7-inch display
*2: Vehicles with 11.6-inch display
The following indicate that charging has been carried out prope rly.
● The charging indicator turns off
● The Hybrid battery (traction battery) status indicators illumin ate for
approximately 15 seconds. ( P. 104)
● “Charging Complete” is displayed on the multi-information displ ay
when starting off ( P. 130)
Regardless of the type of power source or whether the charging timer
function is used, charging is c ompleted if the above can be confirmed.

Driving
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to roa d con-
ditions.
Park the vehicle and shift the shift position to P and block th e wheel
under the vehicle without setting the parking brake. The parkin g brake
may freeze up, preventing it fro m being released. If the vehicle is
parked without setting the parking brake, make sure to block th e
wheels.
Failure to do so may be dangerous because it may cause the vehi cle
to move unexpectedly, possi bly leading to an accident.
Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain
0.12 in. (3.0 mm)
1.18 in. (30.0 mm)
0.39 in. (10.0 mm)
Cross chain 0.16 in. (4.0 mm)
0.98 in. (25.0 mm)
0.55 in. (14.0 mm)
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always chec k local regulations before installing
chains.

■Tire chain installation
Observe the following precautions when installing and removing chains:
● Install and remove tire chains in a safe location.
● Install tire chains on the front tires only. Do not install tir e chains on the rear
tires.
● Install tire chains on front tires as tightly as possible. Reti ghten chains after
driving 1/4 - 1/2 mile (0.5 - 1.0 km).
● Install tire chains following the instructions provided with th e tire chains.
■ Consumption of fuel and electricity
In cold temperatures, resistance of the parts of a vehicle (tra nsmission, tires,
etc.) generally increases, resulting in increase of energy cons umption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of this vehicle is also lik ely to become
worse in cold temperatures.
WARNING
■ Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
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 acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tir e chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that v ehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert with steering control).
■ When parking the vehicle
When parking the vehicle without applying the parking brake, ma ke sure to
chock the wheels. If you do not chock the wheels, the vehicle m ay move
unexpectedly, possibly resulting in an accident.

■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. 482)
■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.

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that hav e been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

When trouble arises
■Emergency tire puncture repair kit
●The emergency tire puncture repair kit is for filling the car tire with air.
●The sealant has a limited life span. The expiry date is marked on the
bottle. The sealant should be repl aced before the expiry date. Contact
your Toyota dealer for replacement.
●The sealant stored in the emergency tire puncture repair kit ca n be used
only once to temporarily repair a single tire. If the sealant i n the bottle
and other parts of t he kit have been used a nd need to be replaced, con-
tact your Toyota dealer.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -4 0°F
(-40°C) to 140°F (60°C).
●The kit is exclusively designed for size and type of tires orig inally
installed on your vehicle. Do not use it for tires that a diffe rent size than
the original ones, or for any other purposes.
●If the sealant gets on yo ur clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immedi ately wipe
away the sealant with a wet cloth.
●During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
●Do not use to che ck or to adjust the tire pressure.
