7-13. Vehicle Stability Control (VSC)/TRAC System■
Vehicle Stability Control
(VSC) System
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Stability Control (VSC) system
adjusts the engine’s output and the
wheels’ respective braking forces to help
maintain traction and directional control.
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 indicated by
flashing of the Vehicle Stability Control
(VSC) operation indicator light.NOTE In the following circumstances, the
vehicle may be less stable than it feels
to the driver. The Vehicle Stability
Control (VSC) system may therefore
operate. Such operation does not indi-
cate a system malfunction. - On gravel-covered or rutted
roads
- On unfinished roads
- When the vehicle is towing a
trailer - When the vehicl
e is fitted with
snow tires or winter tires
 Activation of the Vehicle Stability
Control (VSC) system will cause opera-
tion of the steering wheel to feel
slightly different compared to that for
normal conditions.
 It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Stability Control (VSC) system.
 Always turn off th e engine before
replacing a tire as failure to do so may
render the Vehicle Stability Control
(VSC) system unable to operate
correctly.
■
TRAC System
The TRAC system 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 indicated by flashing of
the Vehicle Stability Control (VSC) opera-
tion indicator light. The TRAC system is
also equipped with the brake LSD func-
tion.
WARNING
 Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.

Parking Your Vehicle
2567-16. Parking Your Vehicle■
Parking Brake
To set the parking brake, depress the
brake pedal firmly and hold it down until
the parking brake lever is fully pulled up.To release the parking brake, pull the
lever up slightly, press the release button,
then lower the lever while keeping the
button pressed.
When the parking brake is set while the
engine is running, the parking brake
warning light illuminates. After starting the
vehicle, be sure that the warning light has
turned off before the vehicle is driven.
Refer to "Brake System Warning Light"

P140.
■
Parking Tips
When parking your vehicle, always
perform the following items.
 Apply the parking brake firmly.
 For MT models, put the shift lever in the
“1” (1st) for upgrade or “R” (Reverse) for a
downgrade.
 For AT models, put the select lever in
the “P” (Park) position.
Never rely on the mechanical friction of
the transmission alone to hold the vehicle.
WARNING
 Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent oper-
ation of the vehicle. Also, on hot
or sunny days, the temperature in
a closed vehicle could quickly
become high enough to cause
severe or possibly fatal injuries to
people.Do not park the vehicle over flam-
mable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near 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, occupants in the
vehicle could die from carbon
monoxide (CO) contained 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.
702782
The braking power of the parking
brake may not be sufficient when
stronger braking power is needed
(e.g., when parking on a steep
slope while towing a trailer).

Hill Start Assist System
258In both these cases, the Hill start assist
system operates under the following
conditions.
 The clutch pedal is depressed while the
brake pedal is also depressed (MT
models).
 The vehicle has stopped with the brake
pedal depressed (AT models).
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the clutch pedal
(MT models only) and accelerator pedal
(all models).
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.
When starting backward facing uphill
 When starting forward facing downhill
 While the parking brake is applied
 While the ignition switch is in the “ACC”
or “OFF” position 
While the Hill start assist indicator light
is illuminated. Refer to "Hill Start Assist
Indicator Light" P150.
When using the Hill start assist system, a
braking effect may be felt even after the
brake pedal has been released. However,
for MT models, this braking effect should
disappear once the clutch pedal is
released.
NOTEA slight jolt may be felt when the vehi-
cle begins to move forward after being
reversed.
701109
CAUTION
The braking power of the Hill start
assist system may not be sufficient
when strong braking power is
needed (e.g., when towing a trailer).

RCTA will stop operating and the BSD/
RCTA warning indicator will appear. - When a malfunction occurs in
the system, including the BSD/
RCTA approach indicator light
 If the BSD/RCTA warning indicator
appears, exercise proper caution. For
details, refer to "BSD/RCTA Warning
Indicator" 
P274.
 In the following cases, the BSD/
RCTA will temporarily stop operating
(or may stop operating) and the BSD/
RCTA OFF indicator will appear. - When the radar sensor becomes
significantly misaligned (If the orien-
tation of the radar sensor is shifted
for any reason, readjustment is
required. Have the sensor adjusted
at a SUBARU dealer.)
- When a large amount of snow or
ice sticks to the rear bumper surface
around the radar sensors
- When the vehicle is driven on a
snow-covered road or in an environ-
ment in which there are no objects
around (such as in a desert) for a
prolonged period of time
- When the temperature around
the radar sensors increases exces-
sively due to long driving on uphill
grades in the summer, etc. - When the temperature around
the radar sensors becomes
extremely low
- When the vehicle battery voltage
lowers
- When the vehicle voltage
exceeds the battery voltage rating
The BSD/RCTA will resume operation
once these conditions are corrected,

may have difficulty detecting the
following vehicles and objects. - Small motorcycles, bicycles,
pedestrians, stationary objects on
the road or road side, etc.
- Vehicles with body shapes that
the radar may not reflect (vehicles
with lower body height such as a
trailer with no cargo and sports
cars)
- Vehicles that are not
approaching your vehicle even
though they are in the detection area
(either on a neighboring lane to the
rear or beside your vehicle when
reversing) (The system determines
the presence of approaching vehi-
cles based on data detected by the
radar sensors.)
- Vehicles traveling at signifi-
cantly different speeds
- Vehicles driving in parallel at
almost the same speed as your
vehicle for a prolonged time
- Oncoming vehicles
- Vehicles in a lane beyond the
neighboring lane
- Vehicles travelling at a signifi-
cantly lower speed that you are
trying to overtake
 On a road with extremely narrow
lanes, the system may detect vehicles

weight of the driver and all passengers,
their belongings, and any optional equip-
ment.■
GVWR and GAWR (Gross
Vehicle Weight Rating and
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.

Flat Tires
308Do not use tire chains on a sealed
tire.Do not tow a trailer.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant.Safely park your vehicle on the
roadside so that you do not
obstruct the flow of traffic and so
that you are able to seal the flat
tire without being in danger.Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the
vehicle will not move.Stop the engine before sealing
the flat tire.Turn on the hazard warning
flasher while sealing the flat tire.Do not attempt to remove foreign
objects like nails or screws that
have penetrated the tire. Leave
them as they are. Never leave the flat tire repair kit
unattended while in use.Only one tire can be repaired with
one bottle of sealant.
The tires can be repaired when
the ambient temperature is −22 °F
( − 30 °C) or higher.
CAUTION
 Remember that the flat tire repair
kit only provides temporary
mobility. Regulations concerning
tire repair after usage of flat tire
repair kit may di ffer from country
to country. We recommend that
you consult your SUBARU dealer
or tire dealer for advice. Store the flat tire repair kit safely
and secure it under the floor of
the trunk. Storing it anywhere in
the passenger compartment is
not advisable because it could
strike an occupant in the event of
a sudden stop or collision and
cause injury. Use the flat tire repair kit with
original vehicle tires only.Do not keep the air compressor
operating for more than 10
minutes, otherwise there is a risk
of overheating.The temperature of the air
compressor may become high.
Be careful not to burn yourself.
When raining, take measures to
prevent the air compressor from
being exposed directly to the
rain. Exposing to rain may cause
a malfunction.Do not use air compressors other
than the one in the repair kit.
Using an air compressor other
than the one in the repair kit may
damage the tires.Do not disassemble or modify the
air compressor to enable the use
of a power supply or a battery
other than DC 12 V.If a temporary puncture repair is
performed with the repair kit, the
Tire Pressure Monitoring System
(TPMS) (if equipped) may not
operate normally.

Vehicle Load Limit – How to
Determine
The load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the vehicle
placard attached to the driver’s side
B-pillar. Locate the statement “
The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs
”
on your vehicle’s placard.
The vehicle placard also shows
seating capacity of your vehicle.
The total load capacity includes the
total weight of driver and all passen-
gers and their belongings, any
cargo, any optional equipment such
as a trailer hitch, roof rack or bike
carrier, etc., and the tongue load of
a trailer. Therefore cargo capacity
can be calculated by the following
method. Cargo capacity = Load limit
− (total
weight of occupants + total weight of
optional equipment)
For information about vehicle
loading, refer to
"Loading Your Vehicle"

P297.▼
Calculating total and load
capacities varying seating
configurations
Calculate the available load
capacity as shown in the following
examples:
Example 1A Vehicle capacity weight of the
vehicle is 800 lbs (363 kg), which is
indicated on the vehicle placard with
the statement “The combined
weight of occupants and cargo
should never exceed 363 kg or 800
lbs”.
For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
CAUTION
Your vehicle is neither
designed nor intended to be
used for trailer towing. There-
fore, never tow a trailer with
your vehicle.
