4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accel-
erator pedal depression amount
can be generated more smoothly
than it is in normal conditions. In
addition, the operation of the air
conditioning system (heating/cool-
ing) will be minimized, improving
the fuel economy. ( P. 3 3 0 )
The Eco-friendly driving is possible
by keeping the indicate of Hybrid
System Indicator within Eco area.
( P.96, 102)
Shift the shift lever to D when
stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift
lever to P when parking. When
using the N, there is no positive
effect on fuel consumption. In the
N, the gasoline engine operates but
electricity cannot be generated.
Also, when using the air condition-
ing system, etc., the hybrid battery
(traction battery) power is con-
sumed.
 Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accelera-
tion and deceleration will make
more effective use of the electric
motor (traction motor) without
having to use gasoline engine
power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (traction
battery) power, resulting in poor
fuel consumption. Battery power
can be restored by driving with
the accelerator pedal slightly
released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical energy
can be regenerated when slowing
down.
Repeated acceleration and decel-
eration, as well as long waits at traf-
fic lights, will lead to bad fuel
economy. Check traffic reports
before leaving and avoid delays as
much as possible. When driving in

Driving
Use fluids that are appropriate to
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 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
Winter driving tips
Carry out the necessary prepa-
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents. Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the 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 accidents.Failure to do so may result in the vehi-
cle being unable to be driven safely, and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains
being used, or 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road sur-faces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-ing operations that cause sudden
engine braking.
●Slow down sufficiently before enter-
ing a curve to ensure that vehicle control is maintained.
●Do not use LTA (Lane Tracing Assist) system. (if equipped)
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer or legitimate tire retailers.This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning valves and transmitters.

the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated 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 exte-
rior 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.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and shift the
shift lever to P without setting the
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park-
ing brake, make sure to block the
wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
 If the vehicle is parked without
setting the parking brake, con-
firm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position without depressing the
brake pedal. If the shift lever can be
shifted from P, there may be a prob-
lem with the shift lock system. Have
the vehicle inspected by any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer
or legitimate tire retailers immedi-
ately.
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
