! Gross Axle Weight (GAW) and
Gross Axle Weight Rating (GAWR)
Gross Axle Weight The total weight applied to each axle
(GAW) must never exceed the Gross Axle
Weight Rating (GAWR). The front and rear
GAWs can be adjusted by relocating
passengers and luggage inside the vehi-
cle. The front and rear GAWR are also
shown on the certification label.
Certification label
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
WARNING
If the trailer is loaded with more
weight in the back of trailer ’s axle
than in the front, the load is taken off
the rear axle of the towing vehicle.
This may cause the rear wheels to
skid, especially during braking or
when vehicle speed is reduced dur-
ing cornering, resulting in over-
steer, spin out and/or jackknifing.
Ensure that the trailer tongue load is from
8 to 11 percent of the total trailer weight
and does not exceed the maximum value
of 200 lbs (90 kg).
NOTE
For vehicles with trailer brakes, the
trailer tongue load exceeds 200 lbs (90
kg) when calculated at 8% of the
maximum total trailer weight.
Even in this case, the maximum value
is 200 lbs (90 kg).
1) Jack
2) Bathroom scale
The tongue load can be weighed with a
bathroom scale as shown in the following
illustration. When weighing the tongue
load, be sure to position the towing
coupler at the height at which it would be
during actual towing, using a jack asshown.
F: Front
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; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute the load as evenly
as possible on both the left and rightsides.
Be sure that all cargo is firmly secured to
prevent a change in weight distribution
while driving. &
Trailer hitches
WARNING
Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is
dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your
vehicle and cause corrosion around
the drilled hole.
CAUTION
. Do not modify the vehicle ex-
haust system, brake system, or
other systems when installing a
hitch or other trailer towingequipment.
. Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.

8-28Driving tips
! Before starting out on a trip
. Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. . Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable. . Check that the tire pressures are
correct.. Check that the vehicle and trailer are
connected properly. Confirm that
–the trailer tongue is connected
properly to the hitch ball. – the trailer lights connector is con-
nected properly and trailer ’s brake
lights illuminate when the vehicle ’s
brake pedal is pressed, and that the trailer ’s turn signal lights flash when
the vehicle ’s turn signal lever is oper-
ated. – the safety chains are connected
properly.– all cargo in the trailer is secured
safety in position.– the side mirrors provide a good
rearward field of view without a sig- nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. ! Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss ofcontrol. . Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate enginerevolution. . Avoid uneven steering, sharp turns and
rapid lane changes.. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit yourvehicle. . Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down immediately but gradually. .
When passing other vehicles, consid-
erable distance 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 practice. 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
dealer.
