■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent refilling, have it checked by your SUBARU dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its
appearance.
●It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pressure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

5-2. Steps to take in an emergency
BRZ_U
(Comes on in
yellow) Cruise control indicator light
Indicates a malfunction in the cruise control system.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your SUBARU dealer as soon as possible.
■ SRS airbag system warning light
→ P. 129
■ Electric power steering warning light (warning buzzer)
The electric power steering warning light may come on and the warning
buzzer may sound when the voltage is low or the voltage drops.
WARNING
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.

*: 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:
API grade
SN (Resource Conserving) or SN PLUS (Resource Conserving)
ILSAC multigrade engine oil
GF-5
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 or SN PLUS)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion: “RESOURCE
CONSERVING” means that the
oil has fuel saving and environ-
mental protection capabilities.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Specification Advisory Com-
mittee) Certification Mark is
displayed on the front of the con-
