240the shift paddle twice in rapid succes-
sion.
If the temperature of the transmis-
sion fluid becomes too high, the “AT
OIL TEMP” warning light will illumi-
nate. Immediately stop the vehicle in a
safe place and let the engine idle until
the warning light turns off.▼ Temporary manual mode driving
While driving with the select lever in “D”, if
a shift paddle is operated, the gear can
temporarily be selected. In this case, “M”
and the selected gear number will be
displayed on the combination meter. (If
the engine speed approaches close to the
red zone, an upshift will automatically be
performed.)1) Upshift
2) Downshift
The selected gear, from “M1” to “M6”, will
be displayed on the combination meter.NOTE In the following situations, tempo-
rary manual mode will be cancelled. - When the vehicle speed is low
- When the accelerator pedal is
depressed continuously for a
certain amount of time or more
- When the accelerator pedal is
depressed heavily
- When the select lever is shifted
to a position other than “D”
- When the “+” shift paddle switch
is held down for a period of time
When a downshift is attempted at a
vehicle speed where a downshift is not
possible (when the engine speed
would enter the red zone if a downshift
is performed), the downshift warning
buzzer will sound to inform the driver
that a downshift cannot be performed.■ Driving TipsNOTEIf the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.
 On a road surface where there is a risk
of wheelspin (for example, a snow- or gravel covered road), you can start off

from a standstill safely and easily by first
selecting Snow mode.
 Always apply the foot or parking brake
when the vehicle is stopped in the “D” or
“R” position.
 Make sure to apply the parking brake
when parking your vehicle. Do not hold
the vehicle with only the transmission.
 Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D” position. Use the brake instead.
 The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
malfunction.

Maintenance and Service11
– CONTINUED –
11-12. Differential Gear OilIt is not necessary to check the gear oil
level. Check that there are no cracks,
damage or leakage. However, the oil
inspection should be performed according
to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
Consult your SUBARU dealer for details.■ Recommended Grade and
ViscosityEach oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
"Manual Transmission and Differential
Gear Oil" P383.
11-13. Manual Transmission OilIt is not necessary to check the transmis-
sion oil level. Check that there are no
cracks, damage or leakage. However,
have the oil inspected by your SUBARU
dealer according to the maintenance
schedule in the “Warranty and Mainte-
nance Booklet”. Consult your SUBARU
dealer for details.■ Recommended Grade and
ViscosityEach oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
"Manual Transmission and Differential
Gear Oil" P383.
11-14. Brake Fluid■ Checking the Fluid Level
CAUTION
Using a differential gear oil other
than the specified oil may cause a
decline in vehicle performance.
WARNING
 Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake
fluid gets in your eyes, immedi-
ately flush them thoroughly with
clean water. Fo r safety, when
performing this work, wearing
eye protection is advisable. Brake fluid absorbs moisture
from the air. Any absorbed mois-
ture can cause a dangerous loss
of braking performance. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
CAUTION
 When adding brake fluid, be
careful not to allow any dirt into
the reservoir. Never splash the brake fluid over
painted surfaces or rubber parts.
Alcohol contained in the brake
fluid may damage them.

■Manual Transmission and Differential Gear Oil*1: The indicated oil quantity is only a guideline. The necessary quantity for replacement may differ slightly depending on the temperature and other
factors. After refilling the gearbox wi th oil, the oil level should be checked.
*2: For more details about maintenance and service, refer to the indicated section.
*3: The vehicle is filled at the factory.
*4: This type of manual transmission oil can be used. However, using this type of oil will increase fuel consumption.
If oil other than “Manual Transmission Gear Oil LV 75W” is used, the following may be experienced:
 The overall performance and function of the transmission may be adversely affected.
 Rattling noises may occur during id ling and fuel consumption may increase.
Never use different brands together.
*5: Using a differential gear oil other than “D ifferential Gear Oil LX” may cause noise, vibrations and increased fuel consumpti on. Never use different
