Test conditions and procedures

All of the following conditions should be satisfied when the drive test is carried out.
1. Engine coolant temperature: 80°C (176°F) or higher (when engine is fully warmed up)
2. Outside air temperature: 5°C (41°F) or higher
3. A/T condition:
  - Selector lever position: D range
  - Overdrive switch: ON
  - Power/economy changeover switch: Power
Carry out one trip monitoring according to the following drive pattern (from starting of the engine until ignition is turned off). (Takes approximately 10 minutes.)
1. After the engine is fully warmed up, turn the ignition switch to OFF.
2. Start the engine, accelerate to between 56 - 64 km/h (35 - 40 mph) and drive at this speed for 300 seconds or more. Then stop the vehicle. Braking and throttle operations can be carried out during this time.
3. After stopping the vehicle, let the engine run at idle for 300 seconds or more, and then turn the ignition switch to OFF. The vehicle should be set to the following condition for idling.
  - A/C switch: OFF
  - Lights, electric cooling fan and all accessories: OFF
  - Transmission: Neutral (A/T for P range)
  - Steering wheel: Straightforward position

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
