The Saris Guardian is a trunk-mounted bike rack designed for standard bike frames. It is not intended for use with tandem or recumbent bicycles, nor for off-road use. Always follow the Saris vehicle compatibility guide to ensure the rack fits your specific vehicle. Do not mount the rack to any type of trailer or RV, including Class B vehicles.

Assembly
The rack requires minimal assembly. Ensure the main frame is unfolded and locked into position. Use the provided clevis pins to secure the arms in one of the three adjustment positions (1, 2, or 3) to achieve the proper fit for your vehicle. Ensure the arms are positioned slightly above level.

Installation
To install the rack on your vehicle:
- Ensure the vehicle is clean where the rack feet will rest.
- Hook the attachment straps to the support hinge line of your trunk or hatch.
- Never attach hooks to glass, unsupported plastic, or roof racks.
- Rest the lower legs on the license plate area or the metal of the trunk. Never rest them on lights, glass, or plastic.
- Tighten all straps securely.
Loading Bikes
When loading bicycles:

- Load the heaviest or largest bike first, closest to the vehicle.
- Ensure bike tires are not directly behind the exhaust pipe to prevent heat damage.
- Use the provided straps to secure the bike frame to the cradles.
- Re-tighten all straps once the bikes are loaded.
- If bike wheels are not parallel to the ground, or if the bike is a full-suspension model, use the optional Bike Beam accessory.
- Remove all loose items from the bike, such as child seats, baskets, locks, lights, and pumps, before driving.
Maintenance
Each use:
- Wipe down the trunk rack feet.
- Avoid letting the rack feet touch the ground.
