When driving
BRZ_U
However, even when in manual mode, the gears will be automatically
changed in the following situations:
●
When vehicle speed drops (downshift only).
● When engine oil temperature is high and engine speed rises close
to the red zone.
■When moving the select lever out of P
If the select lever is pushed sideways before the brake pedal is depressed,
select lever operation may not be possible. Depress the brake pedal before
shifting the select lever out of P.
■ Downshifting restrictions warning buzzer
If downshifting operations are performed at a vehicle speed by which down-
shifting is not possible (when downshifting will cause the engine speed to
enter the red zone), a buzzer will sound to warn the driver that downshifting
cannot be performed.
■ When driving with cruise control activated
Downshifting can be performed even when using cruise control. After down-
shifting, the set speed continues. ( →P. 188, 190)
■ Sport mode
● In sport mode, lower gears are used and gears change at a higher
engine speed.
● If sport mode is changed to while the select lever is in the M position, the
“SPORT” indicator will come on but sport mode controls will not be car-
ried out. Shift the select lever to the D position.
● Sport mode cannot be changed to when driving with cruise control acti-
vated.
■ Snow mode
To prevent slipping, 1
st gear cannot be selected when in snow mode.
■ Sport mode and snow mode automatic deactivation
In the following situations, the driving mode is automatically deactivated:
● When the engine is turned off after driving in sport mode or snow mode.
● When cruise control is activated while driving in sport mode.

Engine coolant temperature
gauge
Displays the engine coolant tem-
perature.
If the engine coolant temperature
gauge needle/indicator enters the
red zone, a buzzer will sound and
a warning message will be dis-
played.
Engine oil temperature gauge
Displays the engine oil tempera-
ture.
Vo l t m e t e r
Displays the charging voltage.
As voltage displayed may
be different from the actual
battery voltage, use the volt-
meter as a guideline.
●Pressing and holding will turn the range value display on the
engine coolant temperature gauge display on/off.

WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working in the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles without a keyless access with push button start system: Be sure the
engine switch is off. With the engine switch in the “ON” position, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. ( →P. 361)
Vehicles with a keyless access with push button start system: Be sure the
push-button ignition switch is off. With the push-button ignition switch in
“ON” mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. ( →P. 361)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
CAUTION
■If you remove the air cleaner element
Driving with the air cleaner element removed may cause excessive engine
wear due to dirt in the air. Also a backfire could cause a fire in the engine
compartment.

Engine oilWith the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to
drain back into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check
the oil level.
When checking the oil, look at both sides of the dipstick and use the
lower measurement to determine the level of oil.
Wipe the dipstick and reinsert it fully. Low

■
Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.

■ Engine oil consumption
Some engine oil will be consumed while driving. The rate of consumption
can be affected by such factors as transmission type, driving style, terrain
and temperature. Under the following conditions, oil consumption can be
increased and thus require refilling between maintenance intervals:
● When the engine is new and within the break-in period
● When the engine oil is of lower quality
● When the incorrect oil viscosity is used
● When engine braking is employed (repeatedly)

5-2. Steps to take in an emergency
BRZ_U
Stop the vehicle immediately.
The following warning indicates the possibility of damage to the vehi-
cle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your SUBARU dealer.
Warning lightWarning light/Details
Charging system warning light Indicates a malfunction in the vehicle’s charging system.
Low engine oil pressure warning light Indicates that the engine oil pressure is too low.
(Flashes or illu- minates in red) High engine coolant temperature warning light (if
equipped)
Indicates that the engine is almost overheating. ( →P. 479)
As the engine coolant temperature increases, this warning
light will change from flashing to constantly illuminated.

Lubrication system
*: The engine oil capacity is a reference quantity to be used when changingthe engine oil. Warm up and turn off the engine, wait more than 5 minutes,
and check the oil level on the dipstick.
■ Engine oil selection
Always use SUBARU approved engine oil. For details, we recom-
mend that you contact your SUBARU dealer.
If approved engine oil is unavailable, another motor oil of matching
quality can also be used.
Oil grade:
ILSAC GF5 multigrade engine oil
API classification SN with the words “RESOURCE CONSERVING”
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN)

oil has fuel saving and environ-
mental protection capabilities.
