• Removable or pivoting ball bars generally do not cause parking aid issues when in the stowed position.

Installation Procedure

Step 1: Access Rear Vehicle Area

Prepare the rear of the Ford C-Max for tow bar installation.

Step 2: Mount Chassis Brackets

Attach the main chassis mounting brackets (labeled 'a') to the vehicle frame using the specified hardware. Torque: 20 ± 2 Nm.

Step 3: Attach Tow Bar Frame

Secure the main tow bar frame to the chassis brackets using M10x45 bolts. Fasten the frame further with M10x40 bolts.

Step 4: Install Side Supports

Mount the side support brackets to the vehicle frame using M10x45 bolts. Torque: 64 Nm.

Step 5: Final Frame Fastening

Complete the frame assembly by attaching remaining components with M10x40 bolts. Torque: 64 Nm.

Step 6: Install Tow Ball Assembly

Attach the tow ball and coupling mechanism (part 2) to the tow bar frame using M12x75 bolts. Torque: 95 Nm.

Step 7: Initial Checks

Perform checks at 0 km and 1000 km after installation.
