OPERATING THE BRAKE SYSTEM
ESP May Reduce the Vehicle Speed
Automatically
To
minimize unexpected deceleration
and reduce the risk of a collision the
operator must:
• Avoid aggressive driving
maneuvers, such as sharp
turns or abrupt lane changes at
high speeds, which might trigger
the stability system.
• Always operate the vehicle safely,
drive defensively, anticipate
obstacles and pay attention
to road, weather, and trafc
conditions. ABS, ATC, and ESP
stability systems are no substitute
for prudent, careful driving.
Towing
Doubles or Triples May
Reduce the Effectiveness of
Stability Systems
ESP is
designed and optimized for
trucks and for tractors that tow single
trailers. If a tractor equipped with
ESP is used to power multiple trailer
combinations (known as “doubles” or
“triples”) the effectiveness of the ESP
system may be greatly reduced.
WARNING!
Exercise extreme care when tow-
ing doubles or triples with a vehicle
equipped with Electronic Stability Pro
-
gram. Excessive speed and aggres-
sive maneuvers, such as sharp turns,
sudden steering inputs or abrupt lane
changes should be avoided because
these maneuvers could cause loss of
vehicle control possibly resulting in an
accident involving death or personal
injury.
Limitations of Stability Systems
The ESP
stability system’s
effectiveness may be greatly reduced
if:
• The load shifts due to improper
retention, accident damage or the
inherently mobile nature of some
loads (for example, hanging meat,
live animals or partially laden
tankers).
• The vehicle has an unusually high
or off-set center of gravity (CG).
• One side of the vehicle drops off
the pavement at an angle that is
too large to be counteracted by a
reduction in speed.
• The vehicle is used to haul double
or triple trailer combinations.
• If very rapidly winding steering
inputs are inputted at high speeds.
