Inspection
conditions

• Engine coolant temperature at engine start: More than −10°C (14°F), less than 60°C

(140

°F)

• Intake air temperature: More than −10°C (14°F)

• Dropping of intake air temperature since engine start: Less than 10°C (18°F)

• Condition of CVT: Selector lever "D" range

Test
procedure

1. Start the engine with all the accessories switched OFF.
2. Drive the vehicle for 6 minutes at the following conditions. (During the monitor)

• Vehicle speed: More than 50 km/h (31 mph)

• Air flow rate: More than 10 g/sec

NOTE: The system is normal if engine coolant temperature will rise more than 77

• Condition of CVT: Selector lever "D" range

Test
procedure

1. Start the engine with all the accessories switched OFF.
2. Drive the vehicle at 50 km/h (31 mph) for 6 minutes.
