Before driving
PRIUS v_U (OM47784U)
■
Air conditioning on/off
Switch the air conditioning ( ) to off when it is not needed.
Doing so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce t he burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consump-
tion.
Also, as snow tires can cause lar ge amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover,
frequently driving s hort distances will ca use the engine to
repeatedly warm up, which can lead to poor fuel consumption.

When driving
CAUTION
■Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread
pattern and total load capacity. In addition, make sure that the tires are
inflated to the recommended tire inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Maintenance and care
Vehicle exterior
ItemsCheck points
Doors • Do the doors operate smoothly?
Engine hood • Does the engine hood lock sys-
tem work properly?
Fluid leaks • There should not be any signs of
fluid leakage after the vehicle has
been parked.
Tires • Is the tire inflation pressure cor-
rect?
• The tires should not be dam- aged or excessively worn.
• Have the tires been rotated according to the maintenance
schedule?
• The wheel nuts should not be loose.
CAUTION
■ If the hybrid system is operating
Turn the hybrid system off and ensure that there is adequate ventilation
before performing maintenance checks.

Installing tire pressure warning valves and transmittersWhen replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be regi stered in the tire pressure warn-
ing computer and the tire pressure warning system must be initial-
ized. Have tire pressure warning valve and transmitter ID codes
registered by your Toyota dealer. ( P. 392)
■ Tire pressure warning system
Your vehicle is equipped with a tire pressure warning system
that uses tire pressure warning valves and transmitters to detect
low tire inflation pressure before serious problems arise.
( P. 451)
The compact spare tire is not equipped with a tire pressure
warning valve and transmitter.
