When driving
WARNING
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
●The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase.
Have your brakes fixed immediately.
CAUTION
■Pre-driving check
Trapping small animals in the cooling 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.
■When driving the vehicle
Vehicles with an automatic transmission
●If the accelerator and brake pedals are depressed at the same time, driv-
ing torque may be restrained. This is not a malfunction.
●Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.

160 2-1. Driving procedures
CAUTION
Vehicles with a manual transmission
●If the accelerator and brake pedals are depressed at the same time, driv-
ing torque may be restrained. This is not a malfunction.
●Do not shift gears unless the clutch pedal is fully depressed. After shifting,
do not release the clutch pedal abruptly. Doing so may damage the clutch,
transmission and gears.
●Observe the following to prevent the clutch from being damaged.
• Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
• Do not use any gear other than the 1st gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
• Do not use the clutch to hold the vehicle when stopping on an uphill
grade.
Doing so may damage the clutch.
●Do not shift the shift lever to R when the vehicle is still moving. Doing so
may damage the clutch, transmission and gears.
●Do not release the clutch pedal too quickly. Doing so may damage the
transmission.
■When parking the vehicle (vehicles with an automatic transmission)
Always shift the select lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is acci-
dentally depressed. Also set the parking brake.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
●On vehicles with an automatic transmission, 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.

When driving
CAUTION
■Replacement of brake pad and lining
If you continue to drive despite the scraping noise from the audible brake
pad wear indicator, it will result in the need for costly brake rotor repair or
replacement.
■Breaking-in of new brake pads and linings
Pulling the parking brake lever too forcefully may cause the rear wheels to
lock. To avoid this, be certain to pull the lever up slowly and gently.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire (oP. 382)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your SUBARU dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible) and the function of all joints, bearings, etc.

■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■When the keyless access with push button start system indicator light
flashes in yellow
The system may be malfunctioning. Have the vehicle inspected by your
SUBARU dealer immediately.

to “ON” mode, and start the engine after waiting at least 10 seconds. Idling
may be unstable immediately after the engine starts, however, this is not a
malfunction. The keyless access with push button start
system indicator light (green) will flash
quickly.
