Gross Vehicle Weight (GVW) and Gross Vehicle
Weight Rating (GVWR)
Gross Vehicle Weight
The Gross Vehicle Weight (GVW) must never exceed
the Gross Vehicle Weight Rating (GVWR).
Gross Vehicle Weight (GVW) is the combined total of
the weight of the vehicle, driver, passengers, luggage,
trailer hitch, trailer tongue load and any other optional
equipment installed on your vehicle. Therefore, the
GVW changes depending on the situation. Determine
the GVW each time before going on a trip by putting
your vehicle and trailer on a vehicle scale. Certification label
GVWR is shown on the certification plate located on
the driver’s side door jamb.

Gross Axle Weight (GAW) and Gross Axle
Weight Rating (GAWR)
GrossAxleWeight
The total weight applied to each axle (GAW) must nev-
er exceed the Gross Axle Weight Rating (GAWR). The
front and rear GAWs can be adjusted by relocating
passengers and luggage inside the vehicle. The front
and rear GAWR are also shown on the certification
plate.
To check both GVWR and GAWR and to confirm that
the total weight and weight distribution are within safe
driving limits, you should have your vehicle and trailer
weighed at a commercial weighing station. Be sure that all cargo is firmly secured to prevent a
change in weight distribution while driving.
Tongue load
Tongue load
Ensure that the trailer tongue load is from 8 to 11 per-
cent of the total trailer weight and does not exceed the
maximum value of 200 lbs (90 kg).

1) Jack
2) Bathroom scale
The tongue load can be weighed with a bathroom
scale as shown in the illustration above. When weigh-
ing the tongue load, be sure to position the towing cou-
pler at the height at which it would be during actual
towing, using a jack as shown. F: Front of vehicle
The tongue load can be adjusted by proper distribution
of the load in the trailer. Never load the trailer with
more weight in the back than in the front; approximate-
ly 60 percent of the trailer load should be in the front
and approximately 40 percent in the rear. Also, distrib-
ute the load as evenly as possible on both the left and
right sides.
Be sure that all cargo is firmly secured to prevent a
change in weight distribution while driving.

Connecting a trailer
Trailer brakes
If your trailer’s total weight (trailer weight plus its cargo
weight) exceeds 1,000 lbs (453 kg), the trailer is re-
quired to be equipped with its own brake system. Elec-
tric brakes or surge brakes are recommended, and
must be installed properly. Check that your trailer’s
brakes conform with Federal, state/province and/or
other applicable regulations. Your SUBARU’s brake
system is not designed to be tapped into the trailer’s
hydraulic brake system. Please ask your SUBARU
dealer and professional trailer supplier for more infor-
mation about the trailer’s brake system.
Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. Do not directly connect your trailer

Driving tips

Side mirrors
After hitching a trailer to your vehicle, check that the
standard side mirrors provide a good rearward field of
view without significant blind spots. If significant blind
spots occur with the vehicle’s standard side mirrors,
use towing mirrors that conform with Federal, state/
province and/or other applicable regulations. Trailer lights
Connection of trailer lights to your vehicle’s electrical
system requires modifications to the vehicle’s lighting
circuit to increase its capacity and accommodate wir-
ing changes. To ensure the trailer lights are connected
properly, please consult your SUBARU dealer. Check for proper operation of the turn signals, the brake
lights and parking lights each time you hitch up.
Direct splicing or other improper connection of
trailer lights may damage your vehicle

ally.
When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
Backing up with a trailer is difficult and takes prac-
tice. When backing up with a trailer, never accelerate
or steer rapidly. When turning back, grip the bottom of
the steering wheel with one hand and turn it to the left
for a left turn, and turn it to the right for a right turn. If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs performed immediately by the nearest SUBARU deal- er.
Driving on grades
Before going down a steep hill, slow down and shift
into lower gear (if necessary, use 1st gear) in order to
utilize the engine braking effect and prevent overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts. When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating. When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all vehicles)
and AT OIL TEMP warning light (for AT vehicles) since
the engine and transmission are relatively prone to
overheating under these conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3. If your vehicle has an automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or foot
brake. That may cause the transmission fluid to over-
heat. Also, if your vehicle is equipped with an automat-
