ABS (Anti-lock Brake System)
WARNING
Always use the utmost care in driving – overconfidence because
you are driving with an ABS equipped vehicle could easily lead to a serious accident.
CAUTION
The ABS system does not always decrease stopping distance.
You should always maintain a safe following distance from othervehicles. When driving on badly surfaced roads, gravel roads, icy road,
or over deep newly fallen snow, stopping distances may be long-er for a vehicle with the ABS system than one without. When driv-ing under these conditions, therefore, reduce your speed and
leave ample distance from other vehicles. When you feel the ABS system operating, you should maintain
constant brake pedal pressure. Do not pump the brake pedal
since doing so may defeat the operation of the ABS system.
The ABS system p revents the loc k-up of wheels whic h may oc c ur d uring
sud d en b raking or b raking on slip p ery road surfac es . This help s p revent
the loss of steering c ontrol and d irec tional stab il ity c aused b y wheel
loc k-up .
When the ABS system is op erating , you may hear a c h attering noise or
feel a slig ht vib ration in the b rake p ed al. This is normal when the ABS
op erates.
The ABS system will not op erate when the vehic le sp eed is b elow
ap p roximately 6 mp h (10 km/h).
ABS system self-check
You may feel a slig ht shoc k in the b rake p ed al and hear the op erating
sound of ABS from the eng ine c omp artment just after the vehic le is

7-24started . This is c aused b y an automatic func tional
test of the ABS sys-
tem b eing c arried out and d oes not ind ic ate any ab n ormal c ond ition.
ABS warning light
HB4010GA
The ABS warning lig ht c omes on when the ig nition sw itc h is turned to
the “ON ” p osition and g oes out after ab out two sec ond s.
This is an ind ic ation that the ABS system is workin g p rop erly.
CAUTION
If the warning light behaves as follows, the ABS system may not
be working properly.When the warning light is on, the ABS function shuts down; how-
ever, the conventional brake system continues to operate normal-
ly. The warning light does not come on when the ignition switch
is turned to the “ON” position.
The warning light comes on when the ignition switch is turned
to the “ON” position, but it does not go out even when the vehicle
speed exceeds approximately 8 mph (12 km/h). The warning light comes on during driving.
If these occur, have the ABS system repaired at the first available
opportunity by your SUBARU dealer.

7-26
Whenever suspension components, steering components, or
an axle are removed from a vehicle equipped with VDC, have an authorized SUBARU dealer perform an inspection of that system. The following precautions should be observed in order to
ensure that the VDC system is operating properly:
–All four wheels should be fitted with tires of the same size,
type, and brand. Furthermore, the amount of wear should bethe same for all four tires.– Keep the tire pressure at the proper level as shown on the
label attached to the vehicle ’s door pillar.
– Use only the special temporary spare tire to replace a flat
tire.
When d riving on slip p ery road s or making sud d en tur ns to avoid
ob stac les in the vehic le ’s p ath, c ertain situations may oc c ur where the
vehic le may slip sid eways or where the rear of the vehic le may swing
outward . When the VDC system d etermines either of t hese c irc um-
stanc es is ab out to oc c ur, it c ontrols — and op erates in c onjunc tion with
— the Anti-loc k Brake System and the Trac tion Contro l System to sup -
p ress sud d en c hang es in vehic le attitud e and motion , thus imp roving
d irec tional stab ility d uring d riving .
Anti-loc k Brake System (ABS) func tion:
The ABS c ontrols the b rake system elec tronic ally. I t p revents loc king
of the wheels so that d irec tional stab ility and ste ering wheel resp on-
siveness c an b e maintained even when b raking on sli p p ery surfac es.
In the unlikely event that a malfunc tion should oc c ur in the ABS, it will
still b e p ossib le to stop the vehic le using normal b raking .
Trac tion Control System (TCS) func tion:
The TCS limits sp inning of the d rive wheels on slip p ery surfac es; in
this, it help s ensure that an ap p rop riate d eg ree of trac tion and steer-
ing are maintained . The VDC op eration ind ic ator lig ht will turn on
when the TCS ac tivates. Vehic le Dynamic s Control
To assist in maintaining d irec tional stab ility, the VDC help s sup p ress
sid eways slip p ing of the vehic le when the steering wheel is turned
sud d enly or when c ornering on a slip p ery surfac e. T he VDC op eration

ind ic ator lig ht will flash on and off when this sys
tem ac tivates.
NOTE Slight twitching of the brake pedal may be felt when the VDC-sys-
tem operates; a small degree of vehicle or steering wheel shaking may also be noticed in this situation. These are normal effects of
VDC operation and are no cause for alarm. When driving off immediately after starting the engine, a short-
lived operation noise may be noticed coming from the enginecompartment. This noise is generated as a result of a check beingperformed on the VDC system and is normal. Depending on the timing of activation of the brakes, certain situa-
tions may occur just after driving off where the brake pedal seemsto exhibit a jolting motion. This too is a consequence of the VDCoperational check and is normal. Activation of the VDC system will cause operation of the steering
wheel to feel slightly different compared to that for normal condi-tions. Even if the vehicle is equipped with a VDC system, it is important
that winter tires be used when driving on snow-covered or icyroads. (All four wheels should be fitted with tires of the same sizeand brand). Furthermore, if snow chains are to be used, they shouldbe fitted on the front wheels. When a vehicle is fitted with snow
chains, however, the effectiveness of the VDC system is reduced
and this should be taken into account when driving the vehicle insuch a condition. It is always important to reduce speed when approaching a cor-
ner, even if the vehicle is equipped with VDC. All four wheels should be fitted with tires of the same size, type,
and brand; furthermore, the amount of wear should be the same for
all four tires. If these precautions are not observed and non-match-ing tires are used, it is quite possible that the VDC system will beunable to operate correctly as intended. Always turn off the engine before replacing a tire as failure to do
so may render the VDC system unable to operate correctly.

Parking your vehicle
WARNING
Never leave unattended children or pets in the vehicle. They
could accidentally injure themselves or others through inadver- tent operation of the vehicle. Also, on hot or sunny days, the tem-perature in a closed vehicle could quickly become high enoughto cause severe or possibly fatal injuries to them. Do not park the vehicle over flammable materials such as dry
grass, waste paper or rags, as they may burn easily if they comenear hot engine or exhaust system parts. Be sure to stop the engine if you take a nap in the vehicle. If
engine exhaust gas enters the passenger compartment, occu-pants in the vehicle could die from carbon monoxide (CO) con-tained in the exhaust gas.
CAUTION
Never drive while the parking brake is set because this will cause
unnecessary wear on the brake linings. Before starting to drive,always make sure that the parking brake has been fully released.
To set the p arking b rake, p ress the b rake p ed al fir mly and hold it d own
while fully p ulling up the p arking b rake lever.

8-12When the vehic le has b een left p arked after use on
road s heavily c ov-
ered with snow, or has b een left p arked d uring a sn owstorm, ic ing
may d evelop on the b rake system, whic h c ould c ause p oor b raking
ac tion. Chec k for snow or ic e b uild up on the susp en sion, d isc b rakes
and b rake hoses und erneath the vehic le.
If there is c aked snow or ic e, remove it, b eing c ar eful not to d amag e
the d isc b rakes and b rake hoses and ABS harness. n Refueling in cold weather
To help p revent moisture from forming in the fuel s ystem and the risk
of its freezing , use of an antifreeze ad d itive in t he fuel tank is rec om-
mend ed d uring c old weather.
Use only ad d itives that are sp ec ific ally d esig ned f or this p urp ose.
When an antifreeze ad d itive is used , its effec t las ts long er if the tank is
refilled whenever the fuel level reac hes half emp ty .
If your SUBARU is not g oing to b e used for an exten d ed p eriod , it is
b est to have the fuel tank filled to c ap ac ity. Driving on snowy and icy roads
WARNING
Do not use the cruise control on slippery roads such as snowy or icy roads. This may cause loss of vehicle control.
To p revent skid d ing and slip p ing , avoid sud d en b rak ing , ab rup t ac -
c eleration, hig h-sp eed d riving , and sharp turning w hen d riving on
snowy or ic y road s.
Always maintain amp le d istanc e b etween your vehic le and the vehic le
ahead of you to avoid the need for sud d en b raking .
To sup p lement the foot b rake, use the eng ine b rake effec tively to c on-
trol the vehic le sp eed . (Shift into a lower g ear wh en nec essary.)
Avoid shifting d own ab rup tly. Suc h b ehavior c an c au se the wheels to
loc k, p ossib ly lead ing to loss of vehic le c ontrol.
An anti-loc k b rake system (ABS) enhanc es your vehic le’s b raking p er-
formanc e on snowy and ic y road s. Refer to the “ABS (Anti-Loc k Brake
System) ” and “VDC (Vehic le Dynamic s Control) system ” sec tion in
c hap ter 7 for information on b raking on slip p ery su rfac es.

8-24Trailer hitch (if equipped)
WARNING
Never exceed the maximum weight specified for the trailer
hitch. Exceeding the maximum weight could cause an accident resulting in serious personal injuries. Permissible trailer weight
changes depending on the situation. Refer to the next section“ Trailer towing ” for possible recommendations and limitations.
Trailer brakes are required when the towing load exceeds
1,000 lbs. (453 kg). Be sure your trailer has safety chains and that
each chain will hold the trailer ’s maximum gross weight. Towing
trailers without safety chains could create a traffic safety hazardif the trailer separates from the hitch due to coupling damage orhitch ball damage. Be sure to check the hitch pin and safety pin for positive lock-
ing placement before towing a trailer. If the ball mount comes off
the hitch receiver, the trailer could get loose and create a trafficsafety hazard. Use only the ball mount supplied with this hitch. Use the hitch
only as a weight carrying hitch. Do not use with any type ofweight distributing hitch.
The trailer hitc h is d esig ned to tow a Class 1 rate d load . A maximum of
2,000 lbs. (906 kg) g ross trailer weig ht and a maximum of 200 lbs. (90
kg) g ross tong ue weig ht are p ermissib le for the traile r hitc h.
When you tow a trailer, follow the instruc tions in the next sec tion “Trailer
towing ”.
