switches, a two-position On/Off Switch to activate the
engine brake, and a two-position HI-LO Switch to
control the amount of engine braking.

To turn the two-position On/Off Switch on, raise the
paddle. When the two-position switch is on, an
amber LED (light-emitting diode) illuminates inside
the switch.

To turn the two-position HI-LO Switch on high, raise
the paddle (at the HI-LO icon). To turn the two-
position HI-LO Switch on low, lower the paddle (at
the ENG BRK legend). See

Fig. 4.18

.

A three-position switch is used on MBE900 engines
equipped with both the regular engine brake and the
constant-throttle (decompression) brake. It works the
same as the two-position HI-LO switch, except that
there is a third (off) position when the switch is left at
its normal position.

The engine brake turns off automatically or when the
clutch pedal is pressed. On vehicles without a clutch
pedal, the brake pedal can be used to deactivate the
engine brake. For more information about engine
brake operation, see

Chapter 7

.

When the panel lights are on, the HI-LO icon is back-
lit in amber on the HI-LO switch. On both switches,

the ENG BRK legend is backlit in green when the
panel lights are on.

Exhaust Brake Switch, Optional

The optional exhaust brake is controlled by a dash-
mounted rocker switch to help slow the vehicle when
the accelerator is released. See

Chapter 7

under the

heading "Exhaust Braking System, Optional" for addi-
tional information.

To turn the exhaust brake on, press on the upper
part of the rocker (at the light inside the switch). The
exhaust brake turns off automatically. See

Fig. 4.19

or

Fig. 4.20

.

When the exhaust brake switch is on, an amber LED
illuminates inside the switch. When the panel lights
are on, the EXHST BRK legend is backlit in green.

To turn cruise control on, press the upper half of the On/
Off (rocker) switch. To turn cruise control off, press the
lower half of the On/Off (rocker) switch.
