ENGINE BRAKE
WARNING
A vehicle speed retarding device (such as
engine brake) is not intended to replace the
service brake systems on your vehicle nor
intended to bring your vehicle to a stop. A
vehicle speed retarding device is only
intended to reduce the speed of your vehicle
under certain conditions.
Several types of engine brake can be installed
or are standard on certain engines. All are
used to reduce wear on the vehicle brake
linings.
WARNING
When descending significant grades, use the
service brake as little as possible. If the
engine does not slow the vehicle to a safe
speed, apply service brake and shift to a
lower range. Let the engine (and engine
brake) slow the vehicle. Keep brakes cool and
ready for emergency stopping.
VOLVO ENGINE BRAKE (VEB)
On vehicles equipped with the Volvo Engine
Brake (VEB), the engine brake mode is by
default, set to the AUTO mode
at vehicle
start-up.
When running in AUTO mode, the engine
brake is gradually applied to 100% of the
braking power when the driver
pushes the
brake pedal . Since AUTO mode will not
reduce vehicle momentum unless the brakes
are applied, it will have no impact on fuel
consumption.
The driver can also choose two other modes
using the steering wheel switches; Engine brake
LOW
and engine brake HIGH .
When set to the engine brake LOW mode,
50% of the engine brake power will be applied
when the driver
releases the accelerator
pedal . Using engine brake HIGH will apply
100% of the braking power.
It must be noted that since engine brake LOW
and engine brake HIGH will reduce
vehicle speed upon release of the throttle pedal,
they may negatively impact fuel consumption if
used for extended periods of time.
On vehicles equipped with an engine brake
switch, it is possible to deactivate the engine
brake (OFF mode). To do so, the driver must
