Drive Start Control [12/2022 - ]: Procedure
- PAST ACTIVATION CONFIRMATION
- Check if the customer operated the vehicle in a way that would cause the drive start control to operate.
Activation conditions
- Pattern A (When all of the following conditions are met, control starts.)
- The accelerator pedal is open by approximately 1/5 or more.
- The shift lever is moved from P to any forward position D (Including other forward shift positions) or R.
- Pattern B (When all of the following conditions are met, control starts.)
- The accelerator pedal is open by approximately 1/5 or more.
- The shift lever is moved from R to any forward position D (Including other forward shift positions), any forward position D (Including other forward shift positions) to R, or N to R.
HINT:
Depending on the situation, the shift position may not be changed.
Items Controlled
- Hybrid system output is restricted.
Deactivation Conditions
- The accelerator pedal is released.
- The shift lever is in P or N.
HINT:
- The hybrid system output restricted level differs between Pattern A and Pattern B.
- During sudden start restraint control, hybrid system output is adjusted based on the road gradient.
- Drive start control is not activated when TRC is turned off.
- Control will also not operate under the following conditions. (if equipped)
- When TRAIL mode is on
- When multi-terrain select is selected
- Control will also not operate under the following conditions. (if equipped)
