battery SUBARU WRX 2016 Workshop Manual

– When a temporary spare tire
is installed
– When your vehicle is towed
– When the vehicle is stopped
with the manual mode se-
lected
NOTE . A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. When the vehicle is stuck
in snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.
. The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the “ LOCK ” / “ OFF ” position. How-
ever, the initial LSD torque will be
minimized when the battery is discon-
nected and reconnected.
. During cornering or when making
turns (especially when going into the
garage), the rotational difference be-
tween the front and rear wheels may cause a braking effect accompanied by
vibration and noise. This does not
indicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times occurs depending on the driving
condition, however, it does not indicate
a problem.
. Use the center differential indicator
only as a rough indication of the initial
LSD torque.
. If you operate the center differential
control switch while quickly accelerat-
ing or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differ-
ential and does not indicate a problem.
& Temporary release When the driver stops the vehicle and
pulls the parking brake lever after manu-
ally setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver ’ s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored. Continuously variable trans-
mission The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNINGDo not shift from the “ P ” or “ N ”
position into the “ D ” or “ R ” position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION. Shift into the “ P ” or “ R ” position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
. Do not race the engine for more
than 5 seconds in any position
except the “ N ” or “ P ” position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
. Never move the vehicle rearwardStarting and operating/Continuously variable transmission
– CONTINUED –7-23

Starting and operating/Continuously variable transmission
by inertia with the select lever set
in a forward position or move the
vehicle forward by inertia with
the select lever set in the reverse
position. Doing so may result in
an unexpected accident or mal-
function.
. Do not shift from the “ D ” position
into the “ R ” position or vice
versa until the vehicle has com-
pletely stopped. Such shifting
may cause damage to the trans-
mission.
. When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the “ P ” position. Do not park for
a long time with the select lever
in any other position as doing so
could result in a dead battery.
NOTE . When the engine coolant tempera-
ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automatically
shift to the normal timing after the
engine has warmed up. . Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
. When driving a CVT model under
continuous heavy load conditions such
as when climbing a long, steep hill, the
engine speed or the vehicle speed may
automatically be reduced. This is not a
malfunction. This phenomenon results
from the engine control function main-
taining the cooling performance of the
vehicle. The engine and vehicle speed
will return to a normal speed when the
engine is able to maintain the optimum
cooling performance after the heavy
load decreases. Driving under a heavy
load must be performed with extreme
care.
. The continuously variable transmis-
sion is a chain type system that
provides superior transmission effi-
ciency for maximum fuel economy. At
times, depending on varying driving
conditions, a chain operating noise
may be heard that is characteristic of this type of system.

system, including the BSD/RCTA
approach indicator light
. In the following cases, the BSD/
RCTA will temporarily stop operating
(or may stop operating) and the BSD/
RCTA warning indicator will appear.
The BSD/RCTA will resume operation
once these conditions are corrected,
and the BSD/RCTA warning indicator
will disappear. However, if the BSD/
RCTA warning indicator has appeared
for a prolonged time, have the system
inspected at a SUBARU dealer as soon
as possible.
– When the radar sensor becomes
significantly misaligned (If the or-
ientation of the radar sensor is
shifted for any reason, readjust-
ment is required. Have the sensor
adjusted at a SUBARU dealer.)
– When a large amount of snow or
ice sticks to the rear bumper sur-
face around the radar sensors
– When the vehicle is driven on a
snow-covered road or in an envir-
onment in which there are no
objects around (such as in a desert)
for a long time
– When the temperature around
the radar sensors increased exces-
sively due to long driving on uphill
grades in summer, etc. – When the temperature around
the radar sensors becomes extre-
mely low
– When the vehicle battery voltage
lowers
– When the vehicle battery be-
comes overvoltage
. The detectability of the radar sen-
sors is restricted. The BSD/RCTA de-
tection may be impaired and the sys-
tem may not operate properly under the
following conditions.
– When the rear bumper around
the radar sensors is distorted
– When ice, snow or mud adheres
to the rear bumper surface around
the radar sensors
– When stickers, etc. are affixed on
the areas of the radar sensors on
the rear bumper
– During adverse weather condi-
tions such as rain, snow or fog
– When driving on wet roads such
as snow-covered roads and
through puddles
. The radar sensors may not detect or
may have difficulty detecting the fol-
lowing vehicles and objects.
– Small motorcycles, bicycles, pe-
destrians, stationary objects on the
road or road side and 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 approach-
ing your vehicle even though they
are in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when rever-
sing) (The system determines the
presence of approaching vehicles
based on data detected by the radar
sensors.)
– Vehicles traveling at significantly
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
driving in a lane next to the neighbor-
ing lane.7-58

Driving tips/Driving precaution
conditions than a two wheel drive vehicle.
There is little difference in handling,
however, 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 recom-
mended 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
“ Warranty 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 ”
F 9-12. Driving precaution Water 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
weather Carry 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
temperatures 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 after-
wards 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.8-6

Jump starting WARNING. Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you,
thoroughly flush the exposed
area with water immediately. Get
medical help if the fluid has
entered your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and obtain immediate medical
help.
Keep everyone including chil-
dren away from the battery.
. The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.
. Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
. Whenever working on or around
a battery, always wear suitable eye protectors, and remove metal
objects such as rings, bands or
other metal jewelry.
. Be sure the jumper cables and
clamps on them do not have
loose or missing insulation.
Do not jump start unless cables
in suitable condition are avail-
able.
. A running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away
from the cooling fan, belts and
any other moving engine parts.
Removing rings, watches and
ties is advisable.
. Jump starting is dangerous if it
done incorrectly. If you are un-
sure about the proper procedure
for jump starting, consult a com-
petent mechanic.
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables. & How to jump start 1. Make sure the booster battery is 12
volts and the negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and
accessories.
4. Connect the jumper cables exactly in
the sequence illustrated. In case of emergency/Jump starting

nance item is almost due. For details,
refer to “ Maintenance settings ” F 3-79.Maintenance precautions When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize yourself
with the information provided in this
section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
. Testing of an All-Wheel Drive
model must NEVER be per-
formed on a single two-wheel
dynamometer or similar appara-
tus. Attempting to do so will
result in transmission damage
and in uncontrolled vehicle
movement and may cause an
accident or injuries to persons
nearby.
. Always select a safe area when
performing maintenance on your
vehicle. . Always be very careful to avoid
injury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, battery
acid.
. Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
. Always use the proper tools and
make certain that they are well
maintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support the
vehicle.
. Never keep the engine running in
a poorly ventilated area, such as
a garage or other closed areas.
. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only
by your SUBARU dealer.
. Wear adequate eye protection toMaintenance and service/Maintenance schedule
