FITTING
NOTE:
On 3 Door Models only - this towbar requires drilling of the top face of the bumper, which is visible when the rear
door is opened. The drilled holes are blanked off using rubber grommets supplied. This is the method suggested
by Suzuki.
An alternative is to remove the bumper, drill the top face of the rear panel as described below, and re-assemble the
bumper over the top of the Bolt heads (J) – slotting the bumper fixing holes as required to account for the top edge
of the bumper being higher due to the bolt heads underneath.
1. Remove towing eye.
2. Loosely attach Side Brackets (E) and (F) to chassis using fasteners (K) Note: May need to unclip wiring harness from
side of chassis rails to allow fitment.
On 3 door models only:
3. Completely remove the exhaust heat shield or just the two screws securing its rearmost edge, to gain access to the
existing Ø14 mounting holes located under each corner of the shield. (Fitters preference)
4. Using the diagram below, mark out and drill the top of the bumper (Ø30) and top of rear panel (Ø11) for fasteners (J)
5. Assemble Braces (B) to bottom of rear panel with fasteners & Bushes (J). Insert Bushes (J) from underside of rear panel.
6. Cover the exposed bolt heads by inserting the supplied Rubber Grommets into the holes drilled in the top face of the
bumper.
7. Secure Braces (B) to Side Brackets (E) and (F) using fasteners (L). (Note: not all fasteners (L) are required for 3 door
models)
8. Assemble fasteners (H).
9. Go to step 11.
On 5 door models only:
10. Assemble Side Arms (C) & (D) to Side Brackets (E) and (F) using fasteners (L), and to chassis rails using fasteners (G).
11. Assemble Cross Bar (A) to Side Brackets (E) and (F) using fasteners (M), use Bolt Caps to cover Nut and Bolt heads.

13. Fully Tighten all bolts, starting with bolts (K).
