It is permissible to add 3 psi to the standard tire pressure specification if colder temperatures are expect- ed soon.
Tires typically loose 1psi (7kPa) for every 12°F temperature drop. If extreme temperature 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 : +2.4 psi/1 mile)
NOTICE
When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.

To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ -
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year's time, they can offer significant cost and energy savings.

3: If the ACEA C2 engine oil is not available in your country, you are able to use ILSAC GF-3 (or above) or ACEA A3 (or above).

Recommended SAE Viscosity
Number
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.

*1: For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 0W-20 (API SN (or above) or ACEA
C2). However, if the engine oil is not available in your country,
select the proper engine oil using the engine oil viscosity chart.
10W-30
0/5W-20, 0/5W-30
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy and cold weather performance,
however, higher viscosity engine oils are required for satisfactory lubrication
in hot weather.
Using oils of any viscosity other than those recommended could result in
engine damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.

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 be
seen through the windshield from
outside.
The vehicle certification label
attached on the driver's side center
pillar gives the Vehicle Identification
Number (VIN).
