coolant temperature SUBARU LEGACY 2017 6.G Owners Manual

Instruments and controls/Meters and gauges
&Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “Engine overheating ”F9-
13.
& ECO gauge
1) U.S. spec. models
2) Except U.S. spec. models
The ECO gauge shows the difference
between the average rate of fuel con-
sumption since the trip meter was last
reset and the current rate of fuel con-
sumption.
The ECO gauge indicates the current fuel efficiency as shown in the following chart.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
NOTE
.Engine oil, engine coolant, brake
fluid, washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
. When towing a trailer, refer to “Trai-
ler hitch (Outback —if equipped) ”F 8-
19.
Starting and stopping the
engine (models without
push-button ignition switch)
& General precautions when
starting/stopping engine
WARNING
. Never start the engine from out-
side the vehicle (except when
using the remote engine start
system). It may result in an
accident.
. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
. Do not start the engine near dry
foliage, paper, or other flam-
mable substances. The exhaust
pipe and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
. If the engine is stopped during driving, the catalyst may over-
heat and burn.
. When starting the engine, be sure
to sit in the driver ’s seat (except
when using the remote engine
start system).
NOTE
. Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
. For a short time after the engine has
started, the engine speed is kept high.
When the warm-up is completed, the
engine speed lowers automatically.
. On rare occasions, it may be difficult
to start the engine depending on the
fuel and the usage condition (repeated
driving of a distance in which the
engine has not warmed up sufficiently).
In such a case, it is recommended that
you change to a different brand of fuel.
. On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly
such as a rapid start-up and a rapid
acceleration. This is not a malfunction.
. The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.

rapidly pulls away from a standstill. This
phenomenon does not indicate a problem.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.
WARNING
Do 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 lurch forward or backward.
CAUTION
. Observe the following precau-
tions. Failure to observe these
precautions could cause damage
to the transmission.
– Shift into the “P ” or “R ” posi-
tion only after the vehicle has
completely stopped.
– Do not shift from the “D ”
position into the “R ” position
or vice versa until the vehicle
has completely stopped.
. 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 rearward
by inertia with the select lever set
in a forward driving position or
move the vehicle forward by
inertia with the select lever set
in the “R ” position. Doing so may
result in an unexpected accident
or malfunction.
. 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.
Starting and operating/Continuously variable transmission
–CONTINUED –7-25

Starting and operating/X–mode (Outback CVT models)
(40 km/h) or more while the X-mode is
activated, a buzzer will sound once and
the X-mode will be deactivated.
. While the engine is running, if any of
the following conditions is met, the X-
mode will be deactivated. In this case, it
is not possible to activate the X-mode.
–The CHECK ENGINE warning
light/malfunction indicator light illu-
minates.
– The AT OIL TEMP warning light
flashes.
– The ABS warning light illumi-
nates.
– The Vehicle Dynamics Control
warning light illuminates.
. If the engine could overheat be-
cause of a temperature increase of the
engine coolant, it may not be possible
to activate the X-mode. Even while the
X-mode is activated, the X-mode will be
deactivated when the engine coolant
temperature increases.
& Hill descent control function
The hill descent control function will be in
standby mode when the X-mode is acti-
vated and the vehicle speed is less than
approximately 12 mph (20 km/h).
The function will operate when the vehicle
speed is less than approximately 12 mph (20 km/h) and the accelerator ratio is less
than approximately 10%.
The function will turn off when the vehicle
speed is more than approximately 12 mph
(20 km/h) and the accelerator pedal is
depressed.
CAUTION
The braking power of the hill des-
cent control function may not be
sufficient when strong braking
power is needed (e.g., when towing
a trailer (Outback)).
NOTE
.
Even while the hill descent control
function is operating, you can vary the
vehicle speed by using the brake pedal
or accelerator pedal.
. During braking by the hill descent
control function, the hill descent con-
trol indicator will flash.
. The hill descent control function is
operable regardless of the gradient of
the road.
. The hill descent control function
may be considered normal when the
following conditions occur.
–An operating sound is heard
briefly from the engine compart-
ment while the hill descent control function is operating.
–
The sensation of depressing the
brake pedal is different, (harder
than usual etc.) when the brake
pedal is depressed during hill des-
cent control function operation.
! Hill descent control indicator
This indicator appears while the hill
descent control function is in the standby
mode. It flashes while the function is
operating. It will disappear when the
function is in the disabled mode. When
this function is changed from operational
to non-operational, it will disappear when
the vehicle speed reaches more than
approximately 18 mph (30 km/h).

Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place.
& If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
&If no steam is coming from
the engine compartment
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-15.
1. Keep the engine running at idling
speed. 2. Open the hood to ventilate the engine
compartment. Refer to
“Engine hood ”
F 11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the “LOW”
mark, add coolant up to the “FULL ”mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Towing
WARNING
Never tow AWD vehicles with the
front wheels raised off the ground
while the rear wheels are on the
ground, or with the rear wheels
raised off the ground while the front
wheels are on the ground. This will
cause the vehicle to spin away due
to the operation or deterioration of
the center differential.
If towing is necessary, SUBARU recom-
mends it be done by your SUBARU dealer
or a commercial towing service.
In case of emergency/Engine overheating

Maintenance and service/Cooling system
Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap is
removed.
CAUTION
.Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top off the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or type, the maintenance interval is
shortened to that of the mixing
coolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
1) Normal operating range
If the radiator cooling fan does not operate
even when the engine coolant tempera- ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to
“Temperature gauge ”
F 3-12.
Check the fuse and replace it if necessary.
Refer to “Fuses”F 11-38 and “Fuses and
circuits ”F 12-10. If the fuse is not blown,
have the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.

CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
thepipingistoolowfortheoutside
temperature, it may freeze and block the
nozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
Replacement of wiper blades
Grease, wax, insects, or other materials
on the windshield or the wiper blade
results in jerky wiper operation and streak-
ing on the glass. If you cannot remove the
streaks after operating the windshield
washer or if the wiper operation is jerky,
clean the outer surface of the windshield
(or rear window) and the wiper blades
using a sponge or soft cloth with a neutral
detergent or mild abrasive cleaner. After
cleaning, rinse the windshield and wiper
blades with clean water. The windshield is
clean if beads do not form when you rinse
the windshield with water.
CAUTION
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
. When you wish to raise the
passenger-side wiper arm, first
raise the driver-side wiper arm.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting in
scratches.
