Multi-terrain Select Control
Some operating conditions have been changed for the multi-terrain select so that it can be used while the CRAWL control is activated. The CRAWL control is activated when the accelerator pedal is released and the multi-terrain select is activated in the "AUTO" mode when the accelerator pedal is depressed.
When the CRAWL control is deactivated, one of the 5 road modes of "MUD & SAND" "LOOSE ROCK" "MOGUL" "ROCK & DIRT" and "ROCK" can be selected with the mode selector switch.
The "AUTO" mode will be selected automatically when the CRAWL control is activated.
| Multi-terrain Select Road Mode | Transfer Drive Mode | Control | |
|---|---|---|---|
| A-TRC | Control Results | ||
| Mud and Sand | L4 | The wheels are allowed to slip more than usual. | Outputs a large amount of drive force and suppresses deceleration feeling by assuming that the vehicle is driving on a soft, slippery road surface. |
| Loose Rock | L4 | The wheels are allowed to slip more than usual. | Outputs a large amount of drive force and suppresses deceleration feeling by assuming that the vehicle is driving on slippery or loose-graveled uphill slopes. |
| Mogul | L4 | The wheels are made to grip more than usual. | Suppresses deceleration feeling to achieve smooth driving on hills while improving LSD function by assuming that the vehicle is driving on a highly bumpy road surface. |
| Rock and Dirt | L4 | The wheels are made to grip more than usual. | Gives the wheels grip and improves the LSD function by assuming that the vehicle is driving on a highly bumpy road surface. |
| Rock | L4 | The wheels are made to grip more than usual. | Gives the wheels grip and improves the LSD function by assuming that the vehicle is driving on a highly bumpy road surface. |
| Auto | L4 | The control is optimized in response to the vehicle speeds set in the CRAWL control. | An optimum Active TRC will automatically be selected by further depressing the accelerator pedal to add more traction force while running with the CRAWL control activated. |

Console Switch
The designs of the CRAWL ON/OFF switch, turn assist ON/OFF switch, CRAWL speed/MTS mode select switch, and VSC OFF switch have been altered and they are built into the integration control and panel assembly (console module switch), integrating them on the console and allowing the driver to keep his/her driving posture when using those traction and drive related switches.
