OPERATION 125
Automatic Traction Control (ATC) (If Equipped)
Automatic Traction Control (ATC) provides improved traction on slippery surfaces by
reducing wheel spin. The system operates automatically as follows:
•
If a drive wheel starts to spin, ATC applies air pressure to the brake of the spinning
wheel. Doing this transfers engine torque to the wheels that have better traction.
•
If all drive wheels are spinning, ATC limits engine torque which, in turn, reduces wheel
spin to provide improved traction.
When ATC automatically becomes active, the ATC indicator lamp turns on to alert the
operator. The lamp turns off when the wheel(s) stops spinning.
Heavy Mud/Snow Function (If Equipped)
ATC may also include a heavy mud/snow function which allows the operator to activate
ATC when additional traction is needed. This function is activated with the ATC mode
switch which is located on the dashboard. The heavy mud/snow function increases available
traction by increasing permissible wheel spin.
When the operator selects the heavy mud/snow function, the ATC indicator lamp blinks
continuously. The ATC lamp stops blinking when the ATC mode switch is turned off.
GOOD DRIVING HABITS
Weight Ratings
Do not overload the vehicle. The gross vehicle mass (GVM) and gross combination mass
(GCM) for a given model may vary due to the tyres, wheels/rims, suspensions, axles and/or
frame of a specific vehicle. For safety and durability reasons, do not exceed the GVM and
GCM’s listed on your vehicle’s Certification Label.
Instruments
Glance at the instruments frequently. When problems develop, take prompt steps to correct
them.
