■
Driving in the rain
● Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be
especially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road
surface, preventing the steering and brakes from operating properly.
■ Breaking in your new Toyota
To extend the life of the vehicle, the following precautions are recommended
to observe:
● For the first 180 miles (300 km):
Avoid sudden stops.
● For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 462)
■ For efficient use
● Put the shift lever into “D” when driving
In the “N” position, the gasoline engine operates but electricity cannot be
generated.
The hybrid battery (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
● Drive your vehicle smoothly
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the traction motor without
having to use gasoline engine power.

124 2-1. Driving procedures
PRIUS_U_(OM47614U)
●Avoid repeated acceleration
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
● Push the “P” position switch when parking
In the “N” position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the “N” position for an extended period of the
time may discharge the hybrid battery. The vehicle cannot run if the
hybrid battery is discharged.
■ Normal characteristics after turning off the hybrid system
Approximately five hours after the hybrid system is turned off, you may hear
sound coming from under the vehicle for several minutes. This is because
the fuel evaporation leakage check is performed. It does not indicate a mal-
function.

136 2-1. Driving procedures
PRIUS_U_(OM47614U)
■If the hybrid system does not start
The hybrid system immobilizer system may not have been deactivated.
(P. 82)
■ If the “READY” light does not come on
If the “READY” light does not come on when you press the power switch with
the shift lever in “P” and the brake pedal pressed, contact your Toyota dealer
immediately.
■ When the “POWER” switch in dicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Toy-
ota dealer immediately.
■ Auto power OFF function
The “POWER” switch will automatically turn OFF when left in ACCESSORY
mode for 1 hour or more.
■ Electronic key battery depletion
 P. 4 4
■ When the electronic key battery is discharged
 P. 392
■ Conditions affecting operation
 P. 4 2
■ Leak detection pump
Several hours after the engine is turned off, you may hear a sound coming
from underneath the luggage compartment for several minutes.
This is normal operation and does not indicate a malfunction.

gency. If the hybrid system stops while the vehicle is being driven, this could
lead to an unexpected accident.

Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods if the hybrid system is not operating.

ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of 12 volt battery electrolyte.
● 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.

CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
■To prevent 12 volt battery discharge
Do not leave the automatic air conditioning system on longer than necessary
when the hybrid system is not operating.
