■
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 the 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 consumption.
Also, as snow tires can cause large 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 car-
rying 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 driv-
ing short distances will cause 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. 390)
■ 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. 449)
The compact spare tire is not equipped with a tire pressure
warning valve and transmitter.

Maintenance and care
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating front and rear tires which have different tire infla-
tion pressures
● When changing the tire size
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
Park the vehicle in a safe pl ace and turn the “POWER” switch
off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 502)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure level.
Turn the “POWER” switch to ON mode.

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage.
●A tire goes flat repeatedly or c
annot be properly repaired due to the
size or location of a cut or other damage.
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
driving for about 20 minutes, the tire pressure warning light blinks for
1 minute and stays on to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAW R) of either the front axle or the
rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. ( P. 508)
