tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body.
Remember to drive with care at all times
regardless of the type of tires on your
vehicle.&Tire chains
CAUTION
You cannot use tire chains on your
vehicle because of the lack of clear-
ance between the tires and vehicle
body.NOTEEven though you cannot use tire
chains, use of another type of traction
device (such as spring chains) may be
acceptable if use on your vehicle is
recommended by the device manufac-
turer, taking into account tire size and
road conditions. Follow the device
manufacturer’s instructions, especially
regarding maximum vehicle speed.
To help avoid damage to your vehicle,drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and
use it on the front wheels only. Always
use the utmost care when driving with a
traction device. Overconfidence be-
cause you are using a traction device
could easily lead to a serious accident.
&Rocking the vehicleIf you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between
“1”/“D”and“R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission in
2nd than in 1st (MT models and CVT
models).
If your vehicle is a CVT model, for
information about holding the transmissionin the 2nd position, refer to“Selection of
manual mode”F7-25.

.Do not tow a trailer.
.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant.
.Safely park your vehicle on the
roadside so that you do not
obstruct the flow of traffic and
so that you are able to seal the flat
tire without being in danger.
.Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the vehi-
cle will not move.
.Stop the engine before sealing
the flat tire.
.Turn on the hazard warning
flasher while sealing the flat tire.
.Do not attempt to remove foreign
objects like nails or screws that
have penetrated the tire. Leave
them as they are.

.Remember that the flat tire repair
kit only provides temporary mo-
bility. Regulations concerning
tire repair after usage of flat tire
repair kit may differ from country
to country. We recommend that
you consult your SUBARU dealer
or tire dealer for advice.
.Store the flat tire repair kit safely
and secure it in the cargo area.
Storing it anywhere in the pas-
senger compartment is not advi-
sable because it could strike an
occupant in the event of a sudden
stop or collision and cause injury.

Engine overheating
WARNING
Never attempt to remove the radiator
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 cool-
ant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.&If steam is coming from the
engine compartment.Turn off the engine and get everyone
away from the vehicle until it cools down.
.Contact an authorized SUBARU deal-
er.
&If no steam is coming from the
engine compartment1. Keep the engine running at idling
speed.
2. Open the engine hood to ventilate the
engine compartment. Refer to“Engine
hood”F11-9.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.Temperature gauge
1) Normal operating rangeIf temperature gauge stays in the over-
heated zone, turn off the engine. Refer to
“Temperature gauge”F3-11.4. After the engine has fully cooled down,
check the coolant level in the reserve tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
NOTEFor details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-17.
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.
