When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the drivetrain, cause driveability issues, and possibly cause
damage.
CAUTION
If your vehicle is not equipped with a compact spare tire, your vehicle will be equipped with a Tire Mobility Kit.

It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if colder temperatures are expected soon. Tires typically loose 7 kPa (1 psi) for every 7°C (12°F) temperature drop. If extreme temper-
ature variations are expected, recheck your tire pressure as necessary to keep them properly inflated.
An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan to drive a high-altitude area, check the tire pressures in advance. If necessary, inflate them to a prop-
er level (Air inflation per altitude: +10 kPa/1 km (+2.4 psi/1 mile)).

Specifications and Reporting Safety Defects
The vehicle identification number
(VIN) is the number used in register-
ing your car and in all legal matters
pertaining to its ownership, etc.
The number is punched on the floor
under the passenger seat. To check
the number, open the cover.The VIN is also on a plate attached
to the top of the dashboard. The
number on the plate can easily beseen through the windshield from
outside.
The vehicle certification label attached
on the driver's side center pillar gives
the Vehicle Identification Number(VIN).

FCEV : Fuel Cell Electric Vehicle

H2
An FCEV is an electric vehicle which is driven using the electricity generated from the fuel cell.
The power system of the FCEV is composed of the following:
- The fuel cell stack which generates the electricity
- The device which controls the heat generated after supplying the hydrogen and air for chemical reaction of the stack
- The inverter which converts the DC created from the stack to AC
- The traction motor which generates propelling power using the supplied AC- Air processing system- Fuel processing system
The hydrogen tanks that stores the hydrogen supplied to the fuel cell can be fueled at 70 MPa. ❈FCEV is Fuel Cell Electric Vehicle
