We recommend that towing be done only by an Authorized Mazda Dealer or a commercial tow-truck service.
Proper lifting and towing are necessary to prevent damage to the vehicle. Government and local laws must be followed.
A towed vehicle usually should have its drive wheels (front wheels) off the ground. If excessive damage or other conditions prevent this, use wheel dollies.

When towing with the rear wheels on the ground, release the parking brake.
