•Loosen the two adjustable hub assemblies by untightening the two knobs. • Move the upper support leg until the SR3161/SR3152 is set approximately
to the same angle as in Step 2 that closely resembles your vehicle. Hold the
SR3161/SR3152 in place to check for correct adjustment. Only the upper
support leg may rest on glass. Tighten the hubs by tightening the two knobs.
The bike support arms should be angled slightly upward about 15°.

4 ATTACH UPPER HOOKS
• Once you have the SR3161/SR3152 assembled to its proper setting, place it on
the vehicle. Now attach the two upper hooks into the slot at the leading edge
of the trunk or hatch lid. Adjust the straps lengths so the SR3161/SR3152 stays
in place on the car in the desired position. The bike support arms should now
be tilted slightly upward as Step 3B.
CAUTION: Make sure that all the hooks are attached to metal, not fiberglass, plastic or glass.
5 ATTACH LATERAL HOOKS
• Position the lateral hooks to the outside edge of the trunk lip, hatch lip or
rear door lip. The hook location will be determined when the straps are under
tension. The straps should always be at a 90° angle from the attached edge.
6 ATTACH LOWER HOOKS
• Attach the two lower strap hooks, the preferred location is the bottom edge of the trunk/
hatch. If this location is not working, try the underside of the bumper (if the bumper is
secure enough), or metal frame members under the vehicle. Be sure that the strap is not
rubbing against sharp objects that could cut the straps. TIGHTEN ALL STRAPS.
•Left and right tow hooks under the vehicle.
•Holes or edge of the metal bumper, behind the plastic bumper cover.

7 MOUNTING BICYCLES ONTO YOUR TRUNK-MOUNTED BICYCLE CARRIER
• Place the bicycle(s) onto the SR3161/SR3152
support arms in the bicycle cradles. Make sure
to cover the pedal closest to the vehicle to help
prevent it from scratching the vehicle. Position
or placement direction of the bicycles will vary
according to the type of bicycle and size frame.
Secure the bicycle(s) to the SR3161/SR3152
support leg with the 80" strap.
• Making figure 8 shapes around the last bicycle
frame and the SR3161/SR3152 arms with the
80" strap (see illustration). We recommend to
use extra shock cord or rope on the bicycles to
prevent the wheels from turning and to prevent
the frames from swaying into each other. Do
not allow the bicycle tires to rest close to the
exhaust pipe to prevent them from melting.
RE-TIGHTEN ALL STRAPS AND HUB ASSEMBLIES
AS THE EXTRA LOAD OF PLACING THE BICYCLE(S)
ON THE SR3161/SR3152 MAY HAVE LOOSENED
THE STRAPS. Check the bicycle(s) and SR3161/
SR3152 at regular intervals during use, more
frequently on bumpy roads, and immediately if
the bicycle(s) shift position.
• For maximum security, we recommend that a
simple knot be tied at the end of the buckle.
The trunk-mounted bicycle carrier should be
removed when not in use to avoid additional
wear on both the vehicle and the carrier.
• Tighten the bottom straps while applying
pressure to the bike support arms. Check
for straps tightness, before and after adding
bicycles, tighten as necessary. For maximum
security, tie a simple knot at the end of the
buckle.
