Conversion to SI Units (Système International d'Unités)
-
All numerical values in this manual are based on SI units. Numbers shown in conventional units are converted from these values.
Rounding Off
-
Converted values are rounded off to the same number of places as the SI unit value. For example, if the SI unit value is 17.2 and the value after conversion is 37.84, the converted value will be rounded off to 37.8.
Upper and Lower Limits
-
When the data indicates upper and lower limits, the converted values are rounded down if the SI unit value is an upper limit and rounded up if the SI unit value is a lower limit. Therefore, converted values for the same SI unit value may differ after conversion. For example, consider 2.7 kgf/cm2 in the following specifications:
-
210—260 kPa {2.1—2.7 kgf/cm2, 30—38 psi}
-
270—310 kPa {2.7—3.2 kgf/cm2, 39—45 psi}
-
The actual converted values for 2.7 kgf/cm2 are 264 kPa and 38.4 psi. In the first specification, 2.7 is used as an upper limit, so the converted values are rounded down to 260 and 38. In the second specification, 2.7 is used as a lower limit, so the converted values are rounded up to 270 and 39.
Service Cautions
Injury/damage Prevention Precautions
Depending on the vehicle, the cooling fan may operate suddenly even when
the ignition is switched to off. Therefore, keep hands and tools away from the

Fog Lights
Use this switch to turn on the fog lights.
The fog lights will improve visibility at
night and during foggy conditions.
To turn the fog lights on, rotate the fog
light switch to the position.
The headlight switch must be in the
position before turning on the fog lights.

Security Setting (Type A)
If a passcode is set, the system cannot be
activated unless the passcode is input.
NOTE
Do this function only when parked. It is
too distracting to attempt while driving
and you may make too many errors to be
effective.

Power Steering
Power steering is only operable when
the engine is running. If the engine is
off or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult ...
