Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the 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 installation 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 equipment, or from any
errors or omissions in the instructions
accompanying such equipment or for your
failure 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 maintenance
will be required due to the additional load. (Refer to
“Maintenance schedule under
severe driving conditions ”in the “Warranty
and Maintenance Booklet ”.)
Under no circumstances should a trailer
be towed with a new vehicle or a vehicle
with any new powertrain component (en-
gine, 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 explained in the following.
Exceeding the maximum load limits
could cause personal injury and/or
vehicle 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 accepta- ble.
! Total trailer weight
Total trailer weight
The total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum weight. ! Legacy
The total trailer weight must not exceed
1,000 lbs (453 kg). ! Outback
The maximum total trailer weight is in-
dicated in the following tables. Driving tips

9-12In case of emergency
Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place.
& If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down. & If no steam is coming from
the engine compartment
For details about how to check the coolant
level or how to add coolant, refer to“ Engine coolant ”F 11-18.
1. Keep the engine running at idlingspeed.
2. Open the hood to ventilate the engine compartment. Refer to
“Engine hood ”
F 11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the coolant temperature high warning
light illuminates, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the “MIN ”
mark, add coolant up to the “MAX ”mark.
Refer to “Engine coolant ”F11 - 1 8 f o r
details.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it. TowingWARNING
Never tow AWD vehicles (including
AT, MT and CVT) with the front
wheels raised off the ground while
the rear wheels are on the ground,
or with the rear wheels raised off the
ground while the front wheels are on
the ground. This will cause the
vehicle to spin away due to the
operation or deterioration of the
center differential.
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following

Continuously variable trans-
mission fluid
There is no continuously variable trans-
mission fluid level gauge. It is unneces-
sary to check the continuously variable
transmission fluid level. However, if ne-
cessary, we recommend that you consult
your SUBARU dealer for inspection. Front differential gear oil
(AT and CVT models) &
Checking the oil level
NOTE
There are no differential oil level
gauges for CVT models.
1) Yellow handle
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the level gauge, wipe it clean,
and insert it again.
1) Upper level
2) Lower level
3. Pull out the level gauge again and
check the oil level on it. If it is below the
lower level, add oil to bring the level up to
the upper level.
CAUTION
Be careful not to spill front differ-
ential gear oil when adding it. If oil
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.

&Recommended grade and viscosity

oils and additives. Never use different
brands together.

Remove the plug from the filler hole and
check the oil level. The oil level should be
kept even with the bottom of the filler hole. If the oil level is below the bottom edge of
the hole, add oil through the filler hole to
raise the level.
CAUTION
. Be careful not to spill rear differ-
ential gear oil when adding it. If
rear differential gear oil touches
the exhaust pipe, it may cause a
bad smell, smoke, and/or a fire. If
rear differential gear oil gets on
the exhaust pipe, be sure to wipe
it off.
. If the vehicle requires frequent
refilling, there may be an oil leak.
If you suspect a problem, have
the vehicle checked at your
SUBARU dealer.
