– CONTINUED –
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 andtheir belongings, any optional equipment such as a
trailer hitch, roof rack or bike carrier, etc., and the
tongue load of a trailer.
The tire information label also shows recommended
tire inflation pressure under full loading and trailer
towing conditions. Adjust tire inflation pressures
according to the loading conditions. For the tire inflation pressures, refer to the
“Tires and wheel ”
section in Chapter 11. GVWR and GAWR (Gross Vehicle
Weight Rating and Gross Axle WeightRating)
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

Trailer lights
Connection of trailer lights to your vehicle ’s electrical
system requires modifications to the vehicle ’s light-
ing circuit to increase its capacity and accommo-
date wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU
dealer. Check for proper operation of the turn sig-nals, the brake lights and parking lights each timeyou hitch up.
CAUTION
Direct splicing or other improper connection
of trailer lights may damage your vehicle ’s
electrical system and cause a malfunction ofyour vehicle ’s lighting system.
Tires
Make sure that all the tires on your vehicle are prop-
erly inflated to the pressure specified on the tire
placard located on the left center pillar of your ve-hicle.
Trailer tire condition, size, load rating and proper
inflation pressure should be in accordance with the trailer manufacturer
’s specifications.
In the event your vehicle gets a flat tire when towing
a trailer, ask a commercial road service to repair the
flat tire.
If you carry a regular size spare tire in your vehicle
or trailer as a precaution against getting a flat tire,
be sure that the spare tire is firmly secured.
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not
designed to sustain the towing load. Use ofthe temporary spare tire when towing canresult in failure of the spare tire and/or less
stability of the vehicle.
Trailer towing tips
CAUTION
Never exceed 45 mph (72 km/h) when tow-
ing a trailer in hilly country on hot days. When towing a trailer, steering, stability,
stopping distance and braking performancewill be different from normal operation. For

Temporary spare tire (if equipped)
The temporary spare tire is smaller and lighter than
a conventional tire and is designed for emergency
use only. Remove the temporary spare tire and re-
install the conventional tire as soon as possible be-
cause the spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare
tire periodically to keep the tire ready for use. The
correct pressure is 60 psi (4.2 kg/cm2
, 420 kPa) .
When using the temporary spare tire, note the fol-lowing: Do not exceed 50 mph (80 km/h).
Do not put a tire chain on the temporary spare tire.
Because of the smaller tire size, a tire chain will not
fit properly. Do not use two or more temporary spare tires at
the same time. Do not drive over obstacles. This tire has a smaller
diameter, so road clearance is reduced.
