◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are appro-
priate for the season.
◆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
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeatedly
warm up, which can lead to excess fuel consumption.

Winter driving tips
●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 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 chains match
the size of the tires.
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 windshield.
● Check for and remove any excess ice 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 man-
ner appropriate to the prevailing weather conditions.

■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 tire chains on the rear
tires.
● Install tire chains on front tires as tight ly as possible. Retighten chains after
driving 0.5 - 1.0 km (1/4 - 1/2 mile).
● Install tire chains following the instru ctions provided with the tire chains.
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 specified size.
● Maintain the recommended level of air pressure.
● Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified 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 vehicle 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 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 vehicle con-
trol is maintained.
■ When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move
unexpectedly, possibly resulting in an accident.

2865-1. Using the air conditioning system and defogger
PRIUS +_OM_OM47B24E_(EE)■
When the outside temperature is low
The dehumidification function may not operate even when is pressed.
■ Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. ( →P. 480)
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air condi tioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
■ Air conditioning filter
→ P. 357
■ Customization
Settings (e.g. A/C auto switching operation) can be changed.

WARNING
■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■ When cleaning the windshield (vehic les with rain-sensing windshield
wipers)
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.

Maintenance and care
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota dealers or repairers or other duly
qualified and equipped professionals. For repairs and services covered by
your warranty, please visit an authorized Toyota dealer or repairer, who will
use genuine Toyota parts in repairing any difficulties you may encounter.
There can also be advantages in utilizing authorized Toyota dealers or repair-
ers for non-warranty repairs and services, as members of the Toyota network
will be able to expertly assist you with any difficulties you may encounter.
Your Toyota dealer or repairer, or another duly qualified and equipped profes-
sional will perform all of the scheduled maintenance on your vehicle reliably
and economically due to their experience with Toyota vehicles.
■ Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
●Engine missing, stumbling or pinging
● Appreciable loss of power
● Strange engine noises
● A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
● Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
● Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
● Vehicle pulls to one side when driven straight on a level road
● Strange noises related to suspension movement
● Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature c ontinually higher than normal ( →P. 391, 457)
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
