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 oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. (P.333)
The Eco-friendly driving is pos-
sible by keeping the indicator of
Hybrid System Indicator within
Eco area. ( P.98, 102)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N position,
there is no positive effect on fuel
consumption. In the N position,
the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air
conditioning system, etc., the
hybrid battery (traction battery)
power is consumed.

Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration 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 (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery 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
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic

3444-6. Driving tips
Perform the following according
to the driving conditions:
Do not try to forcibly open a
window or move a wiper that
is frozen. 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 accumulated on the air
inlet vents in front of the wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated 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. Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.

Park the vehicle and move
the shift lever to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels.
Failure to do so may be dan-
gerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an
accident.
When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift lever to P. ( P.243)
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.
 If the vehicle is parked without
setting the parking brake,
confirm 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
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from your Toyota
dealer 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.

depressing the brake pedal. If the
shift lever can be shifted from P,
there may be a problem with the
shift lock system. Have the vehi-
cle inspected by your Toyota
dealer immediately.
Vehicles with 17-inch or 18-
inch tires
Use the tire chains of correct
size and type.
Use SAE Class “S” type radial
tire chains, with the exception of
radial cable chains or V-bar type
chains.
Vehicles with 20-inch tires
Tire chains cannot be mounted.
Snow tires should be used
instead.
Regulations regarding the use
of tire chains vary depending on
location and type of road.
Always check local regulations
before installing chains.
■Tire chain installation
Observe the followi ng 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 tire chains on
the rear tires.
●Install tire chains on front tires as
tightly as possible. Retighten
chains after drivi ng 1/4 - 1/2 mile
(0.5 - 1.0 km).
●Install tire chains following the
instructions provided with the tire
chains.
WARNING
■When parking the vehicle
When parking the v ehicle without
applying the parking brake, make
sure to chock the wheels. If you
do not chock the wheels, the vehi-
cle may move unexpectedly, pos-
sibly resulting in an accident.

When trouble arises
The following may indicate a
problem with your transmission.
Contact your Toyota dealer or
commercial towing service
before towing. 
The hybrid system warning
message is shown on the
multi-information display and
the vehicle does not move.
 The vehicle makes an abnor-
mal sound.
From the front (2WD models)
Release the parking brake.
Turn automatic mode off.
( P.244)
From the front (AWD models)
Use a towing dolly under the
rear wheels.
NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
●Do not tow the vehicle from the
rear when the power switch is
off. The steering lock mecha-
nism is not strong enough to
hold the front wheels straight.
●When raising the vehicle,
ensure adequate ground clear-
ance for towing at the opposite
end of the raised vehicle. With-
out adequate clearance, the
vehicle could be damaged while
being towed.
■To prevent damage to the
vehicle when towing with a
sling-type truck
Do not tow with a sling-type truck,
either from the front or rear.
■Recreational towing (behind
motor home, etc.)
Never dinghy tow your vehicle to
prevent causing serious damage
to the AWD system and transmis-
sion. ( P.230)
