Button Start SystemRefer to "Operating Range for Push-
Button Start System" P125.■ General Precautions When
Starting Engine
NOTEIt may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This
difficulty is caused by the electroni-
cally controlled throttle’s self-diag-
nosis function. To overcome it, keep
the ignition switch in the “ON” position
for approximately 10 seconds before
starting the engine.
 Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
 After the engine starts, the engine
speed will be kept high.
CAUTION
Small animals trapped in the cool-
ing fan and belt of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
WARNING
Never start the engine from
outside the vehicle. It may result
in an accident. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide
poisoning.
 Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
 If the engine is stopped during
driving, the catalyst may overheat
and burn. When starting the engine, be sure
to sit in the driver’s seat.

Driving Tips8

8-8. Winter Driving■Operation during Cold
WeatherCarry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that
contains an antifr eeze solution. Do not
use engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
If you fill the windshield washer tank with
a fluid with a different concentration from
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.-Ride-Handling- Braking- Speedometer/Odometer cali-
bration- Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
 In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a
seat belt. The driver and all your
passengers should fasten their
seatbelts before st arting to drive
in order to minimize the chance of
serious injury or death. Do not make sharp turns or quick
maneuvers unless absolutely
unavoidable. Such actions are
dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
 Whenever strong crosswinds are
present, slow do wn sufficiently to
maintain control of your vehicle. Never to drive through pools and
puddles, or roads flooded with
water. Water entering the engine
air intake or the exhaust pipe or
water splashing onto electrical
parts may damage your vehicle
and may cause it to stall. In this
case, contact your SUBARU
dealer immediat ely. Regardless
of its depth, it can wash away the
ground from under your tires,
resulting in possible loss of trac-
tion and even vehicle rollover.
CAUTION
After driving on gravel roads or
rough roads, check the undercar-
riage of the vehicle body for any
damage, deformation, or paint
removal. If you notice any irregulari-
ties, contact a SUBARU dealer for
an inspection as soon as possible.

Refer to "Hazard Warning Flasher"
 P127.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and
freezing temperatures. Blades of this type
give superior wiping performance in
snowy conditions. Be sure to use blades
that are suitable for your vehicle.NOTEWhen the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.■ Corrosion ProtectionRefer to "Corrosion Protection" P334.
■ Snow Tires
In winter, it may be possible to enhance
performance through use of tires
designed specifically for winter driving
conditions.
If you choose to install winter tires on your
vehicle, be sure to use the correct tire size
and type.
You must install four winter tires that are of
the same size, construction, brand and
load range and you should never mix
radial, belted bias or bias tires since this
may result in dangerous handling charac-
teristics. When you choose a tire, make
sure that there is enough clearance
between the tire and vehicle body.
CAUTION
During high-speed driving, non-
freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the
vehicle speed.
WARNING
 When replacing or installing
winter tire(s), all four tires must
be the same for the following
items.
(a) Size(b) Speed symbol(c) Load index(d) Circumference(e) Construction(f) Manufacturer(g) Brand (tread pattern)(h) Degrees of wearFor items (a) to (c), you must
obey the specification that is
printed on the tire inflation pres-
sure label. The ti re inflation pres-
sure label is located on the
driver’s center pillar.If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.

 Do not use a combination of
radial, belted bias or bias tires
since it may cause dangerous
handling characteristics and lead
to an accident.

weight of the driver and all passengers,
their belongings, and any optional equip-
ment.■ GVWR and GAWR (Gross
Veh icle Weight Rating an d
Gross Axle Weight Rating)Certification labelThe certification label attached to the
driver’s side center pillar shows GVWR
(Gross Vehicle Weight Rating) and
GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must
never exceed the GVWR. GVW is the
combined total of weight of the vehicle,
fuel, driver, all passengers, luggage, and
any optional equipment. Therefore, the
GVW changes depending on the situation. In addition, the tota
l weight applied to
each axle (GAW) must never exceed the
GAWR. The front and rear GAWs can be
adjusted by relocating luggage inside the
vehicle.
Even if the total weight of your luggage is
lower than the vehicl e capacity weight,
either front or rear GAW may exceed the
GAWR, depending on the distribution of
the luggage.
When possible, the load should be evenly
distributed throughout the vehicle.
If you carry heavy loads in the vehicle, you
should confirm that GVW and front and
rear GAWs are within the GVWR and
GAWR by putting your vehicle on a
vehicle scale, found at a commercial
weighing station.
Do not use replacement tires with a lower
load range than the originals because
they may lower the GVWR and GAWR
limitations. Replacement tires with a
higher load range than the originals do not
increase the GVWR and GAWR limita-
tions.
8-10. Trailer TowingSUBARU assumes no responsibility for
injuries or vehicle damage that may result
from trailer towing, from any trailer towing
equipment or from any errors or omissions
in the instructions accompanying such
equipment. SUBARU warranties do not
apply to vehicle damage or malfunction
caused by trailer towing.

CAUTION
Your vehicle is neither designed nor
intended to be used for trailer tow-
ing. Therefore, never tow a trailer
with your vehicle.

Maintenance Precautions
340NOTESUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against per-
forming these services on a SUBARU
vehicle. Non-SUBARU approved flush-
ing systems use chemicals and/or sol-
vents which have not been tested or
approved by SUBARU. SUBARU war-
ranties do not cover any part of the
vehicle which is damaged by adding or
applying chemicals and/or solvents
other than those approved or recom-
mended by SUBARU.
■ Before Checking or
Servicing in the Engine
Compartment
■When Checking or Servicing
in the Engine Compartment
Do not tamper wi th the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. NEVER
use a circuit tester for these
wiring. If your SRS airbag or
seatbelt pretensioner needs
service, consult your nearest
SUBARU dealer. Check the inside of the engine
compartment to see if there are
any cloths and tools left. If they
are left inside, they may be a
cause of malfunction and fire.
WARNING
 Always stop the engine and apply
the parking brake to prevent the
vehicle from moving. Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after the
engine is stopped. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire. When the ignition switch is in the
“ON” position, the cooling fan
may operate suddenly even when
the engine is stopped. If your
body or clothes come into
contact with a rotating fan, that
could result in serious injury. To
avoid risk of injury, always turn
the push-button i gnition switch to
the “OFF” position and confirm
that the operation indicator on
the switch is turn ed off. Then take
the access key fob out from the
vehicle.
 Before performing any servicing
on a vehicle equipped with a
remote engine start system
temporarily place that system in
the service mode to prevent it
from unexpectedly starting the
engine.
