–Use tire stops under the tires
to prevent the vehicle from
moving.
.Never drive with the parking
brake applied. Doing so will
cause unnecessary wear on the
brake linings. Before driving off,
always make sure that the park-
ing brake has been released and
the brake system warning light
has turned off.
Your vehicle is equipped with an electronic
parking brake. You can apply/release the
parking brake by operating the parking
brake switch.
To apply:Depress the brake pedal and
pull up the parking brake switch.
To release:Press the parking brake
switch firmly while the ignition switch is in
the“ON”position and the brake pedal is
depressed.
When the parking brake is applied while
the ignition switch is in the“ON”position,
the electronic parking brake indicator light
and the indicator light on the parking brake
switch illuminate. Refer to“Brake system
warning light”F3-21.
NOTE.If you press the parking brake switch
under the following conditions, the
parking brake will not be released.
–The ignition switch is in the
“ACC”or“LOCK”/“OFF”position.
–You are not depressing the brake
pedal.
.The electronic parking brake system
uses motors to apply the parking brake.
Therefore, operating sounds from the
motors will be heard when applying or
releasing the parking brake. Make sure
that the motor sounds are heard when
applying or releasing the parking
brake.
.If you operate the parking brake
switch under the following conditions,
a chirp will sound and the electronic
parking brake indicator light will flash.
–when the electronic parking
brake system has a malfunction
–when the electronic parking
brake operation is prohibited tem-
porarily
.When you cannot release the park-
ing brake due to, for example, a system
malfunction, contact your SUBARU
dealer and have your SUBARU dealer
release the parking brake.
.If you stop operating the electronicparking brake switch midway or oper-
ate extremely slowly, the system may
detect an error and turn on the brake
system warning light. However, this
does not indicate a malfunction if the
brake system warning light turns off
after operating the switch.
.When the electronic parking brake
has not been used for a long period of
time, the electronic parking brake may
operate automatically after the ignition
switch is turned to the“LOCK”/“OFF”
position. This occurs due to checking
the proper operation of the electronic
parking brake and does not indicate a
malfunction.
.If you cannot release the electronic
parking brake due to the switch mal-
function, refer to the instructions de-
scribed in“Automatic release function
by accelerator pedal”F7-45.
After activating the electronic parking
brake, you may hear a short sound
several minutes after the electronic
parking brake indicator light illumi-
nates as the system confirms proper
engagement. This sound is different
from the apply and release sound.
This can occur:
–If the brakes are extremely hot.
–If the car is parked on a steep
incline.

New vehicle break-in driving–
the first 1,000 miles (1,600 km)The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
.Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency.
.Do not drive at one constant engine or
vehicle speed, either fast or slow.
.Avoid starting suddenly and rapid ac-
celeration, except in an emergency.
.Avoid hard braking, except in an emer-
gency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones.
Fuel economy hintsThe following suggestions will help to save
fuel.
.Select the proper gear position for the
speed and road conditions.
.Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long as possi-
ble.
.Do not pump the accelerator and avoid
racing the engine.
.Avoid unnecessary engine idling.
.Keep the engine properly tuned.
.Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on the
driver’s side. Low pressure will increase
tire wear and fuel consumption.
.Use the air conditioner only when
necessary.
.Keep the front and rear wheels in
proper alignment.
.Avoid carrying unnecessary luggage or
cargo.
.The indication of the ECO gauge shows
a reference for saving fuel. For details,
refer to“ECO gauge”F3-12.
Engine exhaust gas (carbon
monoxide)
WARNING
.Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
.Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from entering
the vehicle.
.Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
.Avoid remaining in a parked ve-
hicle for a lengthy time while the
engine is running. If that is un-
avoidable, then use the ventila-
tion fan to force fresh air into the
vehicle.
.Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
.If at any time you suspect that

Driving tips for AWD models
WARNING
.Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-
tions.
.Always use the utmost care in
driving–overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
.When you replacing or installing
tire(s), all four tires must be the
same for following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For the items (a) to (d), you must
obey the specification that isprinted on the tire placard. The
tire placard is located on the
bottom of driver’s door pillar.
If all of four tires are not the same
for items (a) to (h), there is a
possibility that serious mechan-
ical damage could occur to the
drive train of your car, and affect
the following.
—Ride
—Handling
—Braking
—Speedometer/Odometer
calibration
—Clearance between the body
and tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
CAUTION
If you use a temporary spare tire to
replace a flat tire, be sure to use the
original temporary spare tire stored
in the vehicle. Using other sizes may
result in severe mechanical damage
to the drive train of your vehicle.
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand. By
shifting power between the front and rear
wheels, SUBARU AWD can also provide
added traction during acceleration and
added engine braking force during decel-
eration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging the
AWD system, you should keep the follow-
ing tips in mind.
.An AWD model is better able to climb
steeper roads under snowy or slippery

conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure to
reduce your speed and maintain an ample
distance from other vehicles.
.Always check the cold tire pressure
before starting to drive. The recommended
tire pressure is provided on the tire
placard, which is located under the door
latch on the driver’s side.
.Frequent driving of an AWD vehicle
under hard-driving conditions such as
steep hills or dusty roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the“War-
ranty and Maintenance Booklet”.
–Engine oil
–Brake fluid
–Rear differential gear oil
–Manual transmission oil (MT mod-
els)
–Continuously variable transmission
fluid (CVT models)
–Front differential gear oil (CVT
models)
.There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to“Towing”
F9-21.
Driving precautionWater 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. Never attempt to
drive through rushing water; regardless of
its depth, it can wash away the ground
from under your tires, resulting in possible
loss of traction and even vehicle rollover.
Winter driving&Operation during cold weath-
erCarry 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 tem-
peratures 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 con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.

–When the vehicle has been left
parked during a snowstorm
Check for snow or ice buildup on
the suspension, disc brakes and
brake hoses underneath the ve-
hicle. If there is caked snow or
ice, remove it, being careful not
to damage the disc brakes and
brake hoses and ABS harness.
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the“1”or“R”position. For CVT models,
place the select lever in the“P”position.
2. Use tire stops under the tires to prevent
the vehicle from moving.
!Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an anti-
freeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used for
an extended period, it is best to have thefuel tank filled to capacity.
&Driving on snowy and icy
roadsTo prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle’s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to“ABS (Anti-lock Brake
System)”F7-35 and“Vehicle Dynamics
Control system”F7-37.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’sintakesystemandmay
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
!Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blade rubbers are not frozen to
the windshield.
If the wiper blade rubbers are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blade rubbers are completely
thawed. Refer to“Climate control”F4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blade rubbers. Refer to
“Defogger and deicer”F3-84.
When driving in snow, if frozen snow starts

to stick on the surface of the windshield
despite wiper operation, use the defroster
and the temperature set for maximum
warmth. After the windshield gets warmed
enough to melt the frozen snow on it, wash
it away using the windshield washer. Refer
to“Windshield washer”F3-74.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop the
vehicle at road side, use the hazard
warning flasher to alert other drivers. Refer
to“Hazard warning flasher”F3-8.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that are
suitable for your vehicle.
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.
NOTEWhen the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.&Corrosion protectionRefer to“Corrosion protection”F10-5.&Snow tires

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.

&Vehicle capacity weightVehicle placardThe load capacity of your vehicle is
determined by weight, not by available
cargo space. The maximum load you can
carry in your vehicle is shown on the
vehicle placard attached to the driver’s
side door pillar. It includes the total weight
of the driver and all passengers and their
belongings, any optional equipment such
as a roof rack or bike carrier, etc.
&GVWR and GAWR (Gross Ve-
hicle Weight Rating and
Gross Axle Weight Rating)Certification labelThe certification label attached to the
driver’s side doorjamb 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.
The GVWR equals Curb Weight (actual
weight of your vehicle–including standard
equipment, fluids, emergency tools and
spare tire assembly) plus the vehiclecapacity weight.
In addition, the total 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 vehicle 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 limita-
tions. Replacement tires with a higher load
range than the originals do not increase
the GVWR and GAWR limitations.
