WARNING
If the Steering Angle Sensor is not re-
calibrated, the Yaw Control system will
not function properly. A uncalibrated
sensor could result in a loss of control
of your vehicle which can lead to an
accident involving death or personal
injury.
Retarders
Ideally, you should always slow your
vehicle with your retarder (where permitted
by law) and use your service brakes only
for stopping completely. Operating this way
will greatly prolong the life of your brakes.
Various retarders are available, which
function against the engine, driveline, or
transmission. These are devices that use
your engine’s power to slow down your
vehicle. They save wear and tear on your
service brakes and can be a safety feature,
too, because they can keep your brakes
from overheating.
WARNING
Do not use any of the vehicle’s retard-
ers in any situation that requires an im-
mediate stop and/or in situations of
poor traction (such as wet, icy or snow
covered roads). Trying to use the re-
tarder instead of the service brakes
may cause a loss of vehicle control,
which may result in an accident involv-
ing death or personal injury.
WARNING
The service brakes must be used in an
emergency. The retarder alone might
not stop you fast enough to prevent an
accident. Failure to comply may result
in death, personal injury, equipment or
property damage.
The retarder is NOT intended as the
primary brake for the vehicle, nor is it an
emergency brake. The retarder only helps
the service brakes by using pressure to
slow the drivetrain. Use the service brakes
for quick stops. Do not use the retarder
when operating on road surfaces with poor
traction (such as wet, icy, or snow covered
roads or gravel). Retarders can cause the
wheels to skid on a slippery surface.
We recommend that you do not use your
engine retarder to slow down when you are
bobtailing or pulling an empty trailer.
This vehicle may have a transmission
retarder. Take your foot off the throttle and
operate the retarder switch. When you do
not need full retarder effect, you can apply
it intermittently (off and on) to cause
gradual or partial slowing. Continuous
application of your retarder will cause your
hydraulic fluid to get hotter. Intermittent
application will help prevent overheating.
