■Tire Pressure Monitoring
System (TPMS) (If Equipped)Low tire pressure warning lightThe tire pressure monitoring system
provides the driver with the warning
message indicated by sending a signal
from a sensor that is installed in each
wheel when tire pressure is severely low.
The tire pressure mo nitoring system will
activate only when the vehicle is driven.
Also, this system may not react immedi-
ately to a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
702780
WARNING
 If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
Otherwise an accident involving
serious vehicle damage and
serious personal injury could
occur.
(1) Keep driving straight ahead
while gradually reducing
speed.(2) Slowly pull off the road to a
safe place.(3) Check the pressure for all
four tires and adjust the pres-
sure to the CO LD tire pres-
sure shown on the vehicle
placard on the center pillar on
the driver’s side.If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, replace it
with a spare tire as soon as pos-
sible.
 When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately one minute.
This indicates the TPMS is unable
to monitor all four road wheels.
Contact your SUBARU dealer as
soon as possible for tire and
sensor replacement and/or
system resetting. When a tire is repaired with liquid
sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid
sealant is used, contact your
nearest SUBARU dealer or other
qualified service shop as soon as
possible. Make sure to replace
the tire pressure warning valve
and transmitter when replacing
the tire. You may reuse the wheel
if there is no damage to it and if
the sealant residue is properly
cleaned off.
If the light illuminates steadily
after blinking for approximately
one minute, promptly contact a
SUBARU dealer to have the sys-
tem inspected.

9-4. Jump Starting■ Battery Precautions
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
702781
WARNING
 Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you, thor-
oughly flush the exposed area
with water immedi ately. Get med-
ical help if the fluid has entered
your eyes.If battery fluid is accidentally
swallowed, imme diately drink a
large amount of milk or water,
and obtain immediate medical
help.Keep everyone including chil-
dren away from the battery.
 The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting. Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
 Whenever working on or around a
battery, always wear suitable eye
protectors, and remove metal
objects such as rings, bands or
other metal jewelry. Be sure the jumper cables and
clamps on them do not have
loose or missing insulation. Do not jump start unless cables in
suitable condition are available. A running engine can be
dangerous. Keep your fingers,
hands, clothing, hair and tools
away from the cooling fan, belts
and any other moving engine
parts. Removing rings, watches
and ties is advisable. Jump starting is dangerous if it is
done incorrectly. If you are
unsure about the proper proce-
dure for jump starting, consult a
competent mechanic.

■How to Jump Start1. Make sure the booster battery is 12
volts and the negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and
accessories.
4. Connect the jumper cables exactly in
the sequence illustrated.

1) Connect one jumper cable to the posi-tive (+) terminal on the discharged
battery.
2) Connect the other end of the jumper
cable to the positive (+) terminal of the
booster battery.
3) Connect one end of the other cable to
the negative ( −) terminal of the booster
battery.
4) Connect the other end of the cable to
the strut mounting nut.Make sure that the cables are not near
any moving parts and that the cable
clamps are not in contact with any other
metal.
5. Start the engine of the vehicle with the
booster battery and run it at moderate
speed. Then start the engine of the
vehicle that has the discharged battery.
6. When finished, carefully disconnect
the cables in exactly the reverse order.

Engine Overheating

In Case of Emergency9
– CONTINUED –
9-5. Engine Overheating■If Steam Is Coming from the
Engine CompartmentTurn off the engine and get everyone
away from the vehicle until it cools down.
■ If No Steam Is Coming from
the Engine Compartment1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment. Refer to "Engine Hood"
 P343.
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 temperature gauge stays in the over-
heated zone, turn off the engine.
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 "Eng ine Coolant" P349.
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

counterclockwise 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.
WARNING
Never 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 coolant,
which could burn you very seri-
ously.
CAUTION
If the engine overheats, the engine
speed or the vehicle speed may be
reduced. Stop the vehicle in a safe
place immediately.

WARNING
Never tow vehicles 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 dam-
age or cause an accident.

324holes, return the plugs to their original
places.■Using a Flat-Bed Truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P” posi-
tion for AT models. Sh ift the shift lever into
the 1st position for MT models.
2. Apply the parking brake firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
■ Towing with All Wheels on
the Ground
WARNING
Use the rear tie-down holes only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip out
of the holes, possibly causing a
dangerous situation.
900488
CAUTION
Transport by flat -bed truck may
cause the headlights to become
misaligned. In such a case, have the
headlight alignment checked by a
SUBARU dealer after transporting
the vehicle by flat-bed truck.
WARNING
 Never turn the ignition switch to
the “OFF” position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it w ill take greater
effort to operate the brake pedal
and steering wheel.
