stop start SUBARU WRX 2016 Workshop Manual

Starting and operating/Hill start assist system (models without electronic parking brake system)
1) Starting forward facing uphill
2) Starting backward facing downhill
A) Brake pedal (both MT models and CVT
models)
B) Clutch pedal (MT models only)
In both these cases, the Hill start assist
system operates under the following con- ditions.
. when the clutch pedal is depressed
while the brake pedal is also depressed
(MT models)
. when the vehicle has stopped with the
brake pedal depressed (CVT 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 “ LOCK ” / “ OFF ” position
. while the Hill start assist warning light/7-50

Starting and operating/Cruise control
(S#) mode is selected, the select lever/
gear position indicator will change
from the current gear position indica-
tion to the “ D ” indication.
& To temporarily cancel the
cruise controlThe cruise control can be temporarily
canceled in the following ways.
. Press the “ CANCEL ” button.
. Depress the brake pedal.
. Depress the clutch pedal (MT models
only).
WARNING
For CVT models, you can cancel the
cruise control by shifting the select
lever into the “ N ” position. However, do not shift the lever into the “ N ”
position while driving except in case
of emergency. If the select lever is
shifted into the “ N ” position, the
engine brake will no longer work.
This could result in an accident.
The cruise control set indicator in the
combination meter disappears when the
cruise control is canceled.
To resume the cruise control after it has
been temporarily canceled and with vehi-
cle speed of approximately 20 mph (30
km/h) or more, press the “ RES/SET ”
switch to the “ RES ” side to return to the
original cruising speed automatically.
The cruise control set indicator in the
combination meter will automatically ap-
pear at this time. & To turn off the cruise control There are two ways to turn off the cruise
control:
. Press the cruise control main button
again.
. Turn the ignition switch to the “ ACC ” or
“ LOCK ” / “ OFF ” position (but only when the
vehicle is completely stopped).
& To change the cruising speed ! To increase the speed (by the “ RES/
SET ” switch)
Press the “ RES/SET ” switch to the “ RES ”
side and hold it until the vehicle reaches
the desired speed. Then, release the
switch. The vehicle speed at that moment
will be memorized and treated as the new
set speed.7-54

! Lane Change Assist (LCA)
1) Operating range
The system notifies the driver of vehicles
approaching at a high speed in the
neighboring lanes. If the system detects
a vehicle approaching at a high speed in
the neighboring lanes, it warns the driver
of dangers by illuminating the BSD/RCTA
approach indicator light(s) on the outside
mirror(s). If the driver operates the turn
signal lever in the direction where the
BSD/RCTA approach indicator light is
illuminating, the system warns the driver
of dangers by flashing the BSD/RCTA
approach indicator light. ! Rear Cross Traffic Alert (RCTA)
1) Operating range
The system notifies the driver of another
vehicle approaching from either side when
driving in reverse. This feature helps the
driver check the rear and side areas of the
vehicle when moving backward.
If the system detects a vehicle approach-
ing from either side while moving back-
ward, it warns the driver of dangers in the
following way.
. The BSD/RCTA approach indicator
light(s) on the outside mirror(s) flashes.
. A warning buzzer sounds. & System operation ! Operating conditions
The BSD/RCTA will operate when all of
the following conditions are met.
. The ignition switch is in the “ ON ”
position.
. The BSD/RCTA warning indicator and
BSD/RCTA OFF indicator are turned off.
. The vehicle is driven at speeds above
6 mph (10 km/h) (except when reversing).
. The shift lever/select lever is in the “ R ”
position (when reversing).
The BSD/RCTA will not operate in the
following situations.
. The BSD/RCTA OFF indicator ap-
pears.
. The vehicle speed is below 6 mph (10
km/h) even when the BSD/RCTA OFF
indicator does not appear (except when
reversing).
NOTE . In the following cases, the BSD/
RCTA will stop operating and the
BSD/RCTA warning indicator will ap-
pear. If the BSD/RCTA warning indica-
tor appears, have your vehicle in-
spected at a SUBARU dealer as soon
as possible.

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

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/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

Driving tips/Loading your vehicle
& Tire chains CAUTIONTire chains cannot be used on your
vehicle because of the lack of
clearance between the tires and
vehicle body.
NOTE When tire chains cannot be used, use
of another type of traction device (such
as spring chains) may be acceptable if
use on your vehicle is recommended
by the device manufacturer, taking into
account tire size and road conditions.
Follow the device manufacturer ’ s in-
structions, especially regarding max-
imum vehicle speed.
To help avoid damage to your vehicle,
drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and
use it on the front wheels only. Always
use the utmost care when driving with
a traction device. Overconfidence be- cause you are using a traction device
could easily lead to a serious accident.
& Rocking the vehicle If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between
“ 1 ” / “ D ” and “ R ” repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than in 1st (MT models and CVT
models).
If your vehicle is a CVT model, for
information about holding the transmission
in the 2nd position, refer to “ Selection of
manual mode ” F 7-26. Loading your vehicle WARNINGNever allow passengers to ride on a
folded rear seatback or in the trunk.
Doing so may result in serious
injury.
WARNING
. Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor as8-10

In case of emergency/Moonroof – if the moonroof does not close
Moonroof (if equipped) – if
the moonroof does not close If the moonroof does not close, we
recommend that you have the system
checked by a SUBARU dealer.
If your vehicle is involved in
an accident CAUTIONIf your vehicle is involved in an
accident, be sure to inspect the
ground under the vehicle before
restarting the engine. If you find that
fuel has leaked on the ground, do
not try to restart the engine. The fuel
system has been damaged and is in
need of repair. Immediately contact
the nearest automotive service facil-
ity. We recommend that you consult
your SUBARU dealer.
Your vehicle has a fuel pump shut off
system. To minimize the risk of fire due to
fuel leakage when the engine stalls or an
airbag inflates upon collision, the system
stops supplying fuel to the engine.
Perform the following procedures to re-
start the engine after the system is
activated.
Models without “ keyless access with
push-button start system ” :
1. Turn the ignition switch to the “ LOCK ”
or “ ACC ” position.
2. Restart the engine. Models with “ keyless access with
push-button start system ” :
1. Turn the push-button ignition switch to
the “ ACC ” or “ OFF ” position.
2. Restart the engine.

Maintenance and service/Maintenance precautions
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU. & Before checking or servicing
in the engine compartment WARNING. Always stop the engine and apply
the parking brake to prevent the
vehicle from moving.
. Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after
the engine has stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. When the ignition switch is in the
“ ON ” position, the cooling fan
may operate suddenly even
when the engine is stopped. If
your body or clothes come into
contact with a rotating fan, that
could result in serious injury. To
avoid risk of injury, perform the
following precautions.
– Models with push-button start
system:
Always turn the push-button
ignition switch to the “ OFF ”
position and confirm that the operation indicator on the
switch is turned off. Then take
the access key out from the
vehicle.
– Models without push-button
start system:
Always remove the key from
the ignition switch.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option) temporarily place
that system in the service mode
to prevent it from unexpectedly
starting the engine.11-4
