namics Control is no guarantee
that full vehicle control will be
maintained at all times and under
all conditions, its activation
should be seen as a sign that
the speed of the vehicle should
be reduced considerably.
. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle, have an inspection of
that system performed by an
authorized SUBARU dealer.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly:
– All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all
four tires.
– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to
the driver ’ s side door pillar.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary
spare tire, the effectiveness of the Vehicle Dynamics Con-
trol system is reduced and
this should be taken into ac-
count when driving the vehi-
cle in such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
. The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely ne-
cessary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to the road surface condition.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine ’ s output and the
wheels ’ respective braking forces to help
maintain traction and directional control.
. Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
flashing the Vehicle Dynamics Control
operation indicator light.
. Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels ’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.

Driving tips/Winter driving
or ice buildup on the suspension,
disc brakes and brake hoses
underneath the vehicle. 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
antifreeze 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
the fuel tank filled to capacity. & Driving on snowy and icy
roads To 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) ” F 7-36 and “ Vehicle Dynamics
Control system ” F 7-38.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control. CAUTIONAvoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’ s intake system and may
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 blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blades are completely thawed.
Refer to “ Climate control ” F 4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to “ Defog-
ger and deicer ” F 3-112.
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 ” F 3-103.8-8

In case of emergency/Towing
Towing If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following
procedures for safety. WARNINGNever tow AWD models (both CVT
and MT models) 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.
& Towing and tie-down hooks The towing hooks should be used only in
an emergency (e.g., to free a stuck vehicle
from mud, sand or snow).
CAUTION
. Use only the specified towing
hook and tie-down hook. Never
use suspension parts or other
parts of the body for towing or
tie-down purposes.
. To prevent deformation to the
front bumper and the towing
hook, do not apply excessive
lateral load to the towing hook. Front towing hook:
1. Take the towing hook, screwdriver and
wheel nut wrench out of the tool bucket.
2. Cover the tip of a flat-head screwdriver
with vinyl tape or cloth so that it will not
scratch the bumper. Insert the flat-head
screwdriver into the cutout of the cover
and pry open the cover.9-12

position for CVT models. Shift 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.
CAUTIONIf your vehicle has a front under-
spoiler and rear underspoiler (both
optional), be careful not to scrape
them when placing the vehicle on
the carrier and when removing the
vehicle from the carrier. & Towing with all wheels on the
ground
1. Release the parking brake and put the
transmission in the “ N ” /neutral position.
2. The ignition switch should be in the
“ ON ” position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.
WARNING
. Never turn the ignition switch to
the “ LOCK ” / “ OFF ” position while
the vehicle is being towed be-
cause the steering wheel and the
direction 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 will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION. If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
. For CVT models, the traveling
speed must be limited to less
than 20 mph (30 km/h) and the
traveling distance to less than 31
miles (50 km). For greater speeds
and distances, transport your
vehicle on a flat-bed truck. In case of emergency/Towing

Appearance care/Corrosion protection
Corrosion protection Your SUBARU has been designed and
built to resist corrosion. Special materials
and protective finishes have been used on
most parts of the vehicle to help maintain
fine appearance, strength, and reliable
operation.
& Most common causes of
corrosionThe most common causes of corrosion
are:
. The accumulation of moisture retaining
dirt and debris in body panel sections,
cavities, and other areas.
. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelerated on the vehicle
when:
. It is exposed to road salt or dust control
chemicals, or used in coastal areas where
there is more salt in the air, or in areas
where there is considerable industrial
pollution.
. It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
. Dampness in certain parts of the vehicle remains for a long time, even
though other parts of the vehicle may be
dry.
. High temperatures will cause corrosion
to parts of the vehicle which cannot dry
quickly due to lack of proper ventilation.
& To help prevent corrosion Wash the vehicle regularly to prevent
corrosion of the body and suspension
components. Also, wash the vehicle
promptly after driving on any of the
following surfaces.
. roads that have been salted to prevent
them from freezing in winter
. mud, sand, or gravel
. coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind
of maintenance and treatment if you need assistance.
Repair chips and scratches in the paint as
soon as you find them.
Check the interior of the vehicle for water
and dirt accumulation under the floor mats
because that could cause corrosion.
Occasionally check under the mats to
make sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated
garage. In such a garage, corrosion can
be caused by dampness. If you wash the
vehicle in the garage or put the vehicle
into the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, and hood latch should
be inspected and lubricated periodically.10-4

the tires. The resulting loss of
vehicle control could lead to an
accident.
& Wheel balance Each wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance causes
the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle ’ s straight-line stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not
correctly balanced, have them checked
and adjusted by your SUBARU dealer.
Also have them adjusted after tire repairs
and after tire rotation.
CAUTION
Loss of correct wheel alignment
causes the tires to wear on one side
and reduces the vehicle ’ s running
stability. Contact your SUBARU
dealer if you notice abnormal tire
wear. NOTE The suspension system is designed to
hold each wheel at a certain alignment
(relative to the other wheels and to the
road) for optimum straight-line stability
and cornering performance.
& Wear indicators
1) New tread
2) Worn tread
3) Tread wear indicator
Each tire incorporates a tread wear
indicator, which becomes visible when
the depth of the tread grooves decreases
to 0.063 in (1.6 mm). A tire must be
replaced when the tread wear indicator
appears as a solid band across the tread. WARNINGWhen a tire ’ s tread wear indicator
becomes visible, the tire is worn
beyond the acceptable limit and
must be replaced immediately. With
a tire in this condition, driving at
high speeds in wet weather can
cause the vehicle to hydroplane.
The resulting loss of vehicle control
can lead to an accident.
NOTE For safety, inspect tire tread regularly
and replace the tires before their tread
wear indicators become visible. Maintenance and service/Tires and wheels

vehicle (bringing the number of
occupants to three), and a child
restraint system weighing 11 lbs (5
kg) is installed in the vehicle for the
child to use, the calculations are as
follows: 1.
Calculate the total weight.
2.
Calculate the available load ca-
pacity. 3.
The total weight now exceeds
the capacity weight by 22 lbs (10
kg), so the cargo weight must be
reduced by 22 lbs (10 kg) or more.
& Determining compatibility of
tire and vehicle load capaci-
ties
The sum of four tires ’ maximum
load ratings must exceed the max-
imum loaded vehicle weight
( “ GVWR ” ). In addition, sum of the
maximum load ratings of two front
tires and of two rear tires must
exceed each axle ’ smaximum
loaded capacity ( “ GAWR ” ). Original
equipment tires are designed to
fulfill those conditions.
The maximum loaded vehicle
weight is referred to Gross Vehicle
Weight Rating (GVWR). And each axle ’ s maximum loaded capacity is
referred to Gross Axle Weight Rat-
ing (GAWR). The GVWR and each
axle ’ s GAWR are shown on the
vehicle certification label affixed to
the driver ’ s door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehi-
cle ’ s suspension, axles and other
parts of the body.
Therefore, this means that the
vehicle cannot necessarily be
loaded up to the tire ’ s maximum
load rating on the tire sidewall.
& Adverse safety conse-
quences of overloading on
handling and stopping and
on tires
Overloading could affect vehicle
handling, stopping distance, and
vehicle and tire performance in the
following ways. This could lead to
an accident and possibly result in
severe personal injury.Consumer information and Reporting safety defects/Tire information
