NOTE
This light also comes on when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it clicks. Make sure no thing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your au-
thorized SUBARU dealer immediately. T If the light is blinking:
If the light is blinking while driving, an en-
gine misfire condition has been detected
which may damage the emission control
system.
To prevent serious damage to the emis-
sion control system, you should do the fol-
lowing.y Reduce vehicle speed.
y Avoid hard acceleration.
y Avoid steep uphill grades.
y Reduce the amount of cargo, if possi-
ble.y Stop towing a trailer as soon as possi-
ble. The CHECK ENGINE warning light may
stop blinking and come on steadily after
several driving trips. You should have
your vehicle checked by an authorized
SUBARU dealer immediately. „
Charge warning light
If this light comes on when the engine is
running, it may indicate that the charging
system is not working properly.
If the light comes on while driving or does
not go out after the e ngine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good con-
dition but the light remains on, contact
your nearest SUBARU dealer immediate- ly. „ Oil pressure warning
light
If this light comes on when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system is not working properly.
If the light comes on while driving or does
not go out after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil
is at the proper level but the light remains
on, contact your nearest SUBARU dealer
immediately. „

warning light (AT vehi-
cles)
The AT oil temperature warning light
comes on when the ignition switch is
turned to the “ON” position and goes out
after approximately two seconds.
If this light comes on when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light comes on while driving, it is un-
necessary to stop the vehicle, but avoid
driving up steep grades or in stop and go
traffic. „ Low tire pressure warn-
ing light (if equipped)
When the ignition switch is turned to the
“ON” position, the low tire pressure warn-
ing light will come on for approximately 2
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.

7-30 Starting and operating
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 ad-
justs the engine’s output and the wheels’
respective braking forces to help maintain
traction and directional control. yTraction 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
steady illumination of the Vehicle Dynam-
ics Control operation indicator light. y 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.
NOTE y Slight twitching of the brake pedal may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or st
eering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm. y When driving off immediately after
starting the engine, a short-lived oper-
ation noise may be noticed coming
from the engine compartment. This
noise is generated as a result of a
check being performed on the Vehicle
Dynamics Control system and is nor- mal.y Depending on the timing of activa-
tion of the brakes, certain situations
may occur just after driving off where
the brake pedal seems to exhibit a jolt-
ing motion. This too is a consequence
of the Vehicle Dynamics Control opera-
tional check and is normal.y In the circumstances listed in the fol-
lowing, the vehicle may be more unsta-
ble than it feels to the driver. The Vehi-
cle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault. yon gravel-covered or rutted roads
y on unfinished roads
y when the vehicle is towing a trailer
y when the vehicle is fitted with snow tires or winter tires
y Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly dif-
ferent compared to that for normal con-
ditions. y Even if the vehicle is equipped with a
Vehicle Dynamics Control system, it is
important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand).
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the ve-
hicle in such a condition. y It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with Ve-
hicle Dynamics Control. y All four wheels shou ld 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-matching tires are used, it is
quite possible that the Vehicle Dynam-
ics Control system will be unable to op-
– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to the
driver’s side door pillar.

NOTE
For better fuel economy, do not carry
unneeded cargo. „Vehicle capacity weight
The load capacity of your vehicle is deter-
mined 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 be-
longings, any optional equipment such as
a trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer.
yWhen you carry something inside
the vehicle, secure it whenever
you can to prevent it from being
thrown around inside the vehicle
during sudden stops, sharp turns
or in an accident.
yDo not pile heavy loads on the
roof. These loads raise the vehi-
cle’s center of gravity and make it
more prone to tip over.
ySecure lengthy items properly to
prevent them from shooting for-
ward and causing serious injury
during a sudden stop.
yNever exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle han-
dles. This could result in loss of
control and cause personal injury.
Also, overloading can shorten the
life of your vehicle.
yDo not place anything on the rear
shelf behind the rear seatback (for
Sedan) or the extended luggage
cover (for Station wagon). Such
items could tumble forward in the
event of a sudden stop or a colli-
sion. This could cause serious in-
jury.
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.

„GVWR and GAWR (Gross Ve-
hicle Weight Rating and
Gross Axle Weight Rating)
Certification label
The certification label attached to the driv-
er’s side door shows GVWR (Gross Vehi-
cle 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, fu-
el, driver, all passengers, luggage, any
optional equipment and trailer tongue
load. Therefore, the GVW changes de-
pending on the situation.
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, ei-
ther 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 load
s 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 vehi-
cle 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 high-
er load range than the originals do not in-
crease the GVWR and GAWR limitations. „
Roof rail and crossbar (if
equipped)
1) Crossbar kit
800237
y For cargo carrying purposes, the
roof rail must be used together
with a roof crossbar kit and the
appropriate carrying attachment.
The roof rail must never be used
alone to carry cargo. Otherwise,
damage to the roof or paint or a
dangerous road hazard due to
loss of cargo could result.

NOTE
Before each use of the roof crossbar,
make sure the four T-30 crossbar
clamp screws have been checked, and
retightened if necessary to 35 lbf·in (4.0
N·m, 0.41 kgf·m), as outlined in Step #5
above.Trailer hitch (if equipped)
The trailer hitch is designed to tow a Class
1 rated load. The maximum gross trailer
weight and maximum gross tongue weight
are indicated in the following table.
When you tow a trailer, follow the instruc-
tions in the next section “Trailer towing”.
y Never exceed the maximum
weight specified for the trailer
hitch. Exceeding the maximum
weight could cause an accident
resulting in serious personal inju-
ries. Permissible trailer weight
changes depending on the situa- tion. Refer to th e next section
“Trailer towing” for possible rec-
ommendations and limitations.
y 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 haza rd if the trailer
separates from the hitch due to
coupling damage or hitch ball
damage.
y Be sure to check the hitch pin and
safety pin for positive locking placement before towing a trailer.
If the ball moun t comes off the
hitch receiver, the trailer could get
loose and create a traffic safetyhazard.
y Use only the ball mount supplied with this hitch. Use the hitch only
as a weight carrying hitch. Do not
use with any type of weight dis-
tributing hitch.

Connecting a trailer
1. Remove the receiver cover from the
hitch receiver tube. Then insert the ball
mount into the hitch receiver tube.
2. Insert the hitch pin into the hole on the
hitch receiver tube so that the pin passes
through the ball mount. 3. Insert the safety pi
n into the hitch pin
securely.
4. Pull the ball mount to make sure it does
not come off the hitch receiver.
1) Hitch ball installation point
2) Hooks for safety chains 5. Use only a hitch ball that is appropriate
for the ball mount and your trailer. The
hitch ball must be securely installed on the
ball mount.
6. Connect your trailer to the hitch ball.
7. Connect the trailer and the hitch with
safety chains that will hold the trailer’s
maximum gross weight. The chains
should cross under the trailer tongue to
prevent the tongue from dropping onto the
ground in case it should disconnect from
the hitch ball. Allow su
fficient slack in the
chains taking tight-turn situations into ac- count; however, be ca reful not to let them
drag on the ground.

er’s wire harness.
9. Confirm proper function of the hitch
wire harness by individually activating the
brake, right turn signal, left turn signal,
stop, and parking lights on the trailer.
NOTE
Always disconnect the trailer wire har-
ness before launching or retrieving awatercraft. „
When you do not tow a trailer
y Remove the ball mount from the hitch
receiver tube and insert the receiver cover
onto the hitch receiver tube. y Place the dust cap over the four-pin
connector of the hitch wire harness to pro-
tect against possible damage. y Occasionally lubricate terminals of the
four-pin connector using the terminal
grease.
Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safe-
ty and satisfaction depend upon proper
use of correct equipment and cautious op-
eration of your vehicle. Seek the advice of
your SUBARU dealer to assist you in pur-
chasing a hitch and other necessary tow-
ing equipment appropriate for your vehi-
cle. In addition, be sure to follow the in-
structions on correct installation and use
provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for in-
juries or vehicle damage that result from
trailer towing equipment, or from any er-
rors or omissions in the instructions ac-
companying such equipment or for your
failure to follow the proper instructions. „ Warranties and maintenance
SUBARU warranties do not apply to vehi-
cle damage or malfunction caused by trail-
er towing. If you use your vehicle to tow a
trailer, more frequent maintenance will be

to “Maintenance schedule under severe
driving conditions” in the “Warranty and
Maintenance Booklet”.)
Under no circumstances should a trailer
be towed with a new vehicle or a vehicle
with any new powertrain component (en-
gine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles
(1,600 km) of driving. „
