HB0382
The load capacity of your vehicle is determined by
weight, not by available cargo space. The maximum
load you can carry in your vehicle is shown as the
Vehicle Capacity Weight on the tire information label
attached to the driver ’s side door jamb. It includes
the total weight of driver and all passengers and their belongings, any optional equipment such as a
trailer hitch, roof rack or bike carrier, etc., and the
tongue load of a trailer.
GVWR and GAWR (Gross Vehicle
Weight Rating and Gross Axle WeightRating)
HGS028CA
The certification plate attached to the driver ’s side
door jamb shows GVWR (Gross Vehicle Weight Rat-
ing) and GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must never ex- ceed the GVWR. GVW is the combined total of
weight of the vehicle, fuel, driver, all passengers,
luggage, any optional equipment and trailer tongue
load. Therefore, the GVW changes depending on
the situation. The GVWR equals Curb Weight (actual weight of your vehicle – including standard equip-
ment, fluids, emergency tools and spare tire assem-

for the trailer hitch. Exceeding the maximum weight could cause an accident resulting inserious personal injuries. Permissible trailerweight changes depending on the situation.Refer to the next section “Trailer towing ” for
possible recommendations and limitations. Trailer brakes are required when the towing
load exceeds 1,000 lbs. (453 kg). Be sure yourtrailer has safety chains and that each chainwill hold the trailer ’s maximum gross weight.
Towing trailers without safety chains could create a traffic safety hazard if the trailer sepa- rates from the hitch due to coupling damageor hitch ball damage. Be sure to check the hitch pin and safety pin

for positive locking placement before towing a
trailer. If the ball mount comes off the hitch re-
ceiver, the trailer could get loose and create atraffic safety hazard.Use only the ball mount supplied with this

hitch. Do not use with any type of weight dis- tributing hitch.
Connecting a trailer
1. Remove the receiver cover from the hitch receiv-
er tube. Then insert the ball mount into the hitch re- ceiver tube.

5. Use only a hitch ball that is appropriate for the
ball mount and your trailer. The hitch ball must be
securely installed on the ball mount.
6. Connect your trailer to the hitch ball.
7. Connect the trailer and the hitch with safetychains that will hold the trailer ’s maximum gross
weight. The chains should cross under the trailer
tongue to prevent the tongue from dropping onto the
ground in case it should disconnect from the hitch
ball. Allow sufficient slack in the chains taking tight –
turn situations into account; however, be careful not
to let them drag on the ground.

Trailer towing
Your car is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a
trailer puts additional loads on your car ’s engine, dri-
vetrain, brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety and sat-
isfaction depend upon proper use of correct equip-
ment and cautious operation of your vehicle. Seekthe advice of your SUBARU dealer to assist you in
purchasing a hitch and other necessary towing
equipment appropriate for your vehicle. In addition,
be sure to follow the instructions on correct installa-
tion and use provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for injuries or
vehicle damage that result from trailer towing equip-
ment, or from any errors or omissions in the instruc- tions accompanying such equipment or for your fail-
ure to follow the proper instructions. Warranties and maintenance
SUBARU warranties do not apply to vehicle damage or malfunction caused by trailer towing. If you use
your vehicle to tow a trailer, more frequent mainte-
nance will be required due to the additional load. (Refer to
“Maintenance schedule under severe driv-
ing conditions ” in the “Warranty and Maintenance
Booklet”.)
Under no circumstances should a trailer be towedwith a new vehicle or a vehicle with any new power-
train component (engine, transmission, differential, wheel bearings, etc.) for the first 1,000 miles (1,600 km) of driving. Maximum load limits
WARNING
Never exceed the maximum load limits ex-
plained below. Exceeding the maximum loadlimits could cause personal injury and/or ve-hicle damage.
CAUTION
Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs (453 kg) total weight. Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make sure the load and its distribution in your
vehicle and trailer are acceptable.
