deviation between expected and
actual yaw rates.
• Gusty winds are strong enough to
cause significant side forces on the
vehicle and any towed vehicles.
To maximize the effectiveness of ESC:
• Loads must be properly secured
and evenly distributed at all times.
• Drivers need to exercise extreme
caution at all times, and avoid sharp
turns, sudden steering inputs or
abrupt lane changes at high speeds,
particularly if:
• The vehicle hauls loads that
could shift,
• The vehicle or load has a high or
off-set center of gravity (CG)
when loaded, or
• The vehicle tows doubles or
triples.
The ESC system was specifically
calibrated and validated only for your
vehicle’s original factory-built configuration.
If your vehicle’s chassis components are
altered (for example; a wheelbase
extension or reduction, tag axle addition or
removal, tractor to truck conversion or
steering system component change) the
ESC system must be disabled immediately
by a qualified mechanic.
WARNING!
Failure to disable ESC "Electronic Stability
Control" when modifying a vehicle could re-
sult in a loss of vehicle control possibly re-
sulting in an accident involving death or per-
sonal injury.
WARNING!
For vehicles equipped with ESC" Electronic
Stability Control" do not replace the vehi-
cle’s steering wheel with an aftermarket or
different part number than originally sup-
plied. Using a different steering wheel could
cause ESC to malfunction causing a loss of
vehicle control possibly resulting in an acci-
dent involving death or personal injury.
Whenever maintenance or repair work is
performed to the steering mechanism,
linkage, gear, adjustment of the wheel
track, or if the steering angle sensor is
replaced or the steering wheel is changed
or re-centered, the Steering Angle Sensor
must be re-calibrated.
WARNING!
If the Steering Angle Sensor is not recali-
brated, the Yaw Control system will not
function properly. A uncalibrated sensor
could result in a loss of control of your vehi-
cle 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.
