CAUTION

Caution indicates an unsafe practice that could result in damage to the product. A caution advisory is in black type on a white background with a black border.

Note: Note indicates a procedure, practice, or condition that must be followed in order for the vehicle or component to function in the manner intended.

Addendum 1

Automatic Traction Control (ATC) (If Equipped)

W3089687	W3089688

ATC Functionally

Automatic Traction Control (ATC) provides improved traction on slippery surfaces by reducing wheel spin. If a drive wheel starts to spin the system operates automatically as follows:

ATC applies air pressure to the brake of the spinning wheel. Doing this transfers engine torque via the axle differential to the wheels that have better traction. Brake control is active at vehicle speed up to 25 MPH.

ATC limits engine torque which, in turn, reduces wheel spin to provide improved traction. The driver may override torque control by further pressing the accelerator pedal. Engine torque is active at all vehicle speeds.

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.

ATC OFF (If Equipped)

ATC may also include the “ATC OFF” option that is selectable to the driver via the ATC OFF switch which is located on the dashboard.

When this function is activated with the ATC OFF mode switch which is located on the dashboard, the ATC OFF function will turn off the Automatic Traction Control (ATC) by allowing torque to be applied to all drive wheel as required by the driver and will not reduce wheel spin by applying the brakes or reducing engine torque.

When the operator selects the heavy ATC OFF function, the ATC indicator lamp be on continuously to indicate that the Automatic Traction Control (ATC) is not available. The ATC lamp will turn off when the ATC OFF mode switch is turned off.

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.

When this function is activated, with the ATC MUD/SNOW 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.

Towing Information

Towing a Vehicle Equipped with mDRIVE Transmission

Vehicles Equipped with AMT-D (mDRIVE) without Towing Alternative Procedure

Note: Refer to label on the driver door to check if vehicle is equipped with Towing Alternative Procedure.

Addendum 3

W4093877

If the vehicle is not equipped with the Towing Alternative Procedure, the driveshaft must be disconnected to tow the vehicle.

CAUTION

Failure to disconnect the drive axle shaft(s) or lift the drive wheels off the ground before towing or pushing the vehicle can cause serious transmission damage.

DANGER

If the driveshaft has been disconnected for towing, DO NOT reuse bearing retainer bolts or stamped strap bolts, or stamped straps. Reuse of bearing retainer bolts or stamped strap bolts, or stamped straps can cause driveline failure, which can result in separation of the driveline from the vehicle.

A separated driveline can result in property damage, serious personal injury or death.

4 Addendum

Vehicles Equipped with AMT-D (mDRIVE) and with Towing Alternative Procedure

Note: This procedure is not intended to replace the standard towing procedures and must only be used when it is not possible to follow the standard procedures.

If the vehicle cannot have the driveshaft removed and is equipped with Towing Alternative Procedure, the vehicle can be towed without the removal of the driveshaft. This procedure allows the vehicle to be removed from toll-ways, bridges, and tunnels without disconnecting the driveshaft.

CAUTION

At the earliest possible time, the vehicle should be configured for standard towing by disconnecting the axle shaft. Failure to disconnect the drive axle shaft(s) or lift the drive wheels off the ground before towing or pushing the vehicle can cause serious transmission damage.

Note: Refer to label on the driver door to check if vehicle is equipped with towing alternative procedure. Also, some vehicles have had the transmission control module (TCM) software updated to add the towing alternative procedure.

When the Towing Alternative Procedure is used, 3rd gear and High Range is engaged which enables the oil pump to rotate during towing. Towing gear 3 HR will be engaged if the following conditions are met:

•Transmission in neutral position

•Vehicle moves forward faster than a set limit for a number of seconds

•Engine is not running

•Air pressure to the transmission must be greater than 700 kPa (100 psi). Air should be supplied continuously from the towing vehicle.

•Ignition ON and power provided to the TCM

•Battery voltage must be 12 volts or higher for proper TCM function

•No transmission air pressure diagnostic trouble codes (DTC)

Addendum 5

CAUTION

Reverse towing is not allowed when Towing Alternative Procedure is used. Reverse towing can damage the transmission.

CAUTION

Do not use the Towing Alternative Procedure if the vehicle has been in an accident that has compromised the oil cooling lines or cooler or if the vehicle is being towed for transmission failure. Using this procedure may result in further damage to the equipment.

This procedure should NOT be used in the following situations.

•Vehicle power and or air supply cannot be verified to the transmission or cannot be consistently supplied from the towing vehicle if moving longer distances.

•Heavy frontal damage to the radiator assembly on vehicles that have the transmission oil cooler in the bottom tank of the radiator, and the cooler lines are compromised. Towing with broken lines will pump all the oil out of the transmission and further damage the equipment.

•Complaints involving transmission failure that requires towing.

•Active air pressure DTC in the Instrument Cluster for the transmission.

6 Addendum

Towing

Note: During towing, the main switch and parking lamps shall be lit if the electrical system of the vehicle is functioning.

Lifting The Front Suspension

W7001301

Note: When the vehicle is towed with the front suspension lifted, the steering lock must be released.

CAUTION

When the driving wheels are still in contact with the ground the axle drive shaft must always be removed in order not to damage the gearbox.

If the half shafts have to be removed, if the rear axle has been damaged for example, the hubs must always be provided with close fitting covers. Sand and dirt could otherwise find their way in and cause considerable damage.

T0006670

Disconnect the propeller shaft from the rear axle and fix it securely to the chassis, or remove the entire propeller shaft.

Addendum 7

ABS

Note: During towing with the front suspension lifted, a fault code for “abnormal sensor signal front” is set in the ABS system. This should be considered during the next service, when the ABS fault codes are checked.

The fault code is deleted with the service tool, please refer to the service information for the ABS system.

Lifting The Rear Suspension

Note: When the vehicle is towed with the rear suspension lifted, the steering wheel must be locked with the steering lock, or lashed.

Method: This method is preferred when the proper equipment is not available to perform the wheel lift method and is necessary for wreckers not equipped with an under lift system.

Unloading

Always unload the vehicle before lifting the rear suspension, if circumstances allow it.

The vehicle is unloaded to reduce the axle loading on the towing vehicle, limit the loading on the vehicle's lifting points and minimize the risk of damage to the load which could occur during towing.

If it is not possible to unload the vehicle where it is, it can be towed a short distance to a suitable place where unloading can take place.
