Published availability and qualifications

Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Enter an authorized off-road area, assess the surface and select H4 or L4 under the transfer-system rules.
- 02
Press the MTS switch and confirm its indicator illuminates.
- 03
Turn MODE SELECT: choose Auto, Sand, Mud or Rock in L4, or Auto, Dirt, Sand, Mud or Deep Snow in H4.
- 04
Confirm the displayed mode before proceeding slowly, then cancel MTS when returning to normal roads.
Important limits
- Multi-Terrain Select is for off-road driving and cannot extend the GX's tire, clearance or stability limits.
- The terrain labels are guidance only; actual pitch, slipperiness and surface shape can make another approach safer.
Quick checks.
- ✓If the expected mode is absent, verify whether H4 or L4 is selected because their lists differ.
- ✓If the indicator will not illuminate or a warning persists, return to a safe surface, cancel the system and arrange Lexus inspection.
