Unbraked (no trailer brakes): 750 kg.

| 2009–2013 | 1,400 | 720 |
| 2013–2017 | 1,600 | 690 |
| 2017–2020 | 1,600 | 710 |

Towing capacity is the manufacturer-rated maximum for the model's strongest variant in each generation, not an average across trims — a base engine will tow less than the figure shown. Cars with an implausible source-data towing figure relative to their own kerb weight are excluded rather than shown with a guessed correction.
