Guidance

Engage lower gear

TGS505

Illustrative image — The manual draws this code sharing one image with sibling code(s) GS505 — shown as printed, not isolated to TGS505 alone.

Where

On the left-hand side of the road.

Purpose

To warn that, because of a steep descent, it is necessary to engage a lower gear.

Action

If you are driving a heavy motor vehicle, engage a lower gear so that the vehicle will move down the descent more slowly. • If the lower gear does not have the desired effect, engage an even lower gear to keep the speed constant and protect the brakes against overheating.
