Tachometer

The tachometer displays the engine speed in revolutions per minute (rpm). For a description of how Grade Braking affects vehicle speed while the Tow/Haul Mode is activated, see Tow/Haul Mode on page 9‑42 for more information.

If the vehicle is a hybrid, see the hybrid supplement for more information.
