TTongue load
Tongue load
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, espe-
cially during braking or when vehicle speed is
reduced during cornering, resulting in over-
steer, spin out and/or jackknifing. 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 below. 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
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. „
Trailer hitches
Never drill the frame or under-body of your ve-
hicle to install a commercial trailer hitch. If you
do, dangerous exhaust gas, water or mud may
enter the passenger compartment through the
drilled hole. Exhaust gas contains carbon mon-
oxide, a colorless and odorless gas which is
dangerous, or even lethal, if inhaled. Also, drill-
ing the frame or under-body of your vehicle
could cause deterioration of strength of your
vehicle and cause corrosion around the drilled
hole.
yDo not modify the vehicle exhaust system,
brake system, or other systems when installing
a hitch or other trailer towing equipment. y Do not use axle-mounted hitches as they can
cause damage to the axle housing, wheel bear-
ings, wheels or tires.
Choose a proper hitch for your vehicle and trailer.

speed. You should also keep the following tips
in mind:
T Before starting out on a trip
y Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are appar-
ent, do not tow the trailer.y Check that the vehicle sits horizontally with the trail-
er 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 con-
firm that the load and its distribution are acceptable. y Check that the tire pressures are correct.
y 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 connected properly
and trailer’s brake lights illuminate when the vehi-
cle’s brake pedal is pressed, and that the trailer’s
turn signal lights flash when the vehicle’s turn signal
lever is operated.
– 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 significant blind spot. y
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. T Driving with a trailer
y 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 of control.y Avoid abrupt starts and sudden accelerations. If
your vehicle has a manual transmission, always start
out in first gear and release the clutch at moderate en-
gine revolution. y Avoid uneven steering, sharp turns and rapid lane
changes. y Slow down before turning. Make a longer than nor-
mal 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 your vehicle. y Crosswinds will adversely affect the handling of
your vehicle and trailer, causing 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 gradu-
ally. y 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
y 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. y 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. T
Driving on grades
y 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.y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating.y 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. y 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-
ic transmission, avoid driving with the gear selector le-
ver in “D” when towing a heavy trailer to prevent fluid

overheating. A lower gear should be used. T
Parking on a grade
Always block the wheels under both vehicle and trailer
when parking. Apply the parking brake firmly. You
should not park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you should take the
following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under both the
vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb the load.
4. Apply the regular brakes and then apply the park-
ing brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmission)
or “P” (automatic transmission) and shut off the en-
gine.

NOTE
[Automatic transmission vehicle not equipped
with VDC (Vehicle Dynamics Control) and not
equipped with SPORTSHIFT] Before driving your
vehicle with the temporary spare tire, put a spare
fuse inside the FWD connector located in the en-
gine compartment and confirm that the Front-
wheel drive warning light comes on. The all wheel
drive capability of the vehicle has now been deac- tivated. After re-installing the conventional tire, re-
move the spare fuse from the FWD connector in
order to reactivate all wheel drive.

Flat tires
yDo not jack up the vehicle on an incline or a
loose road surface. The jack can come out of
the jacking point or sink into the ground and
this can result in a severe accident. y Use only the jack provided with your vehicle.
The jack supplied with the vehicle is designed
only for changing a tire. Never get under the ve-
hicle while supporting the vehicle with thisjack. y Always turn the engine off before raising the
flat tire off the ground using the jack. Never
swing or push the vehicle supported with the
jack. The jack can come out of the jacking point
due to a jolt and this can result in a severe acci-
dent. y Do not use oil or grease on the wheel studs or
nuts when the spare tire is installed. This could
cause the nuts to become loose and lead to an
accident.
If you have a flat tire while driving, never brake sud-
denly; keep driving straight ahead while gradually re- ducing speed. Then slowly pull off the road to a safe
place.
1. Park on a hard, level surface, whenever possible,
then stop the engine.
2. Set the parking brake securely and shift a manual
transmission vehicle in reverse or an automatic trans-
mission vehicle in the “P” (Park) position.
3. Turn on the hazard warning flasher and have ev-
eryone get out of the vehicle.
4. Put wheel blocks at the front and rear of the tire di-
agonally opposite the flat tire.
