Starting and operating
pery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost
and the risk of an accident increased.
The following table shows the maximum speeds that
are possible with each different gear.
Never exceed the speed limit below for each gear po-
sition except for brief acceleration in an emergency.
The tachometer’s needle (if so equipped) will enter the
red area if these speeds are exceeded. Failure to ob-
serve this precaution can lead to excessive engine
wear and poor fuel economy. mph (km/h)
Never exceed posted speed limits. „
Driving tips
Do not drive with your foot resting on the clutch pedal
and do not use the clutch to hold your vehicle at a
standstill on an upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the shift lever.
This may cause wear on the transmission compo-
nents.
When it is necessary to reduce vehicle speed due to
slow traffic, turning corners, or driving up steep hills,
downshift to a lower gear before the engine starts to
labor.
On steep downgrades, downshift the transmission to
4th, 3rd or 2nd gear as necessary; this helps to main-
tain a safe speed and to extend brake pad life.
In this way, the engine provides a braking effect. Re-
member, if you “ride” (over use) the brakes while de-
scending a hill, they may overheat and not work prop-
erly.
The engine may, on rare occasions, knock when the
vehicle rapidly accelerates or rapidly pulls away from
a standstill. This phenomenon does not indicate a
fault.

Starting and operating
Power steering
Do not hold the steering wheel at the fully
locked position left or right for more than five
seconds. This may damage the power steering
pump.
The power steering system operates only when the
engine is running.
If you lose power steering assist because the engine
stops or the system fails to function, you can steer but it will take much more effort.
NOTE
Right after the engine has been started and before
it has warmed up, you may hear a noise coming
from areas adjacent to the power steering pump
which is located at the right-front area of the en-
gine compartment. This noise is normal. It does
not indicate power steering system trouble.
Braking „ Braking tips
Never rest your foot on the brake pedal while
driving. This can cause dangerous overheating
of the brakes and needless wear on the brake
pads and linings.
T When the brakes get wet
When driving in rain or after washing the vehicle, the
brakes may get wet. As a result, brake stopping dis-
tance will be longer. To dry the brakes, drive the vehi-
cle at a safe speed while lightly depressing the brake
pedal to heat up the brakes. T Use of engine braking
Remember to make use of engine braking in addition
to foot braking. When descending a grade, if only the
foot brake is used, the brakes may start working im-
properly because of brake fluid overheating, caused
by overheated brake pads. To help prevent this, shift
into a lower gear to get stronger engine braking.

Starting and operating
– CONTINUED –
TBraking when a tire is punctured
Do not depress the brake pedal suddenly when a tire
is punctured. This could cause a loss of control of the
vehicle. Keep driving straight ahead while gradually
reducing speed. Then slowly pull off the road to a safe
place. „ Brake system
T Two separate circuits
Your vehicle has two separate circuit brake systems.
Each circuit works diagonally across the vehicle. If one
circuit of the brake system should fail, the other half of
the system still works. If one circuit fails, the brake
pedal will go down much closer to the floor than usual
and you will need to press it down much harder. And a
much longer distance will be needed to stop the vehi- cle. T Brake booster
The brake booster uses engine manifold vacuum to
assist braking force. Do not turn off the engine while
driving because that will turn off the brake booster, re-
sulting in poor braking power.
The brakes will continue to work even when the brake
booster completely stops functioning. If this happens,
however, you will have to push the pedal much harder than normal and the braking distance will increase. „
Disc brake pad wear warning indica- tors
The disc brake pad wear warning indicators on the
disc brakes give a warning noise when the brake pads
are worn.
If a squeaking or scraping noise is heard from the disc
brakes while braking, immediately have your vehicle
checked by your SUBARU dealer.

Driving tips
Driving tipsNew vehicle break-in driving – the
first 1,000 miles (1,600 km)
The performance and long life of your vehicle are de-
pendent on how you handle and care for your vehicle
while it is new. Follow these instructions during the
first 1,000 miles (1,600 km):y
Do not race the engine. And do not allow engine
speed to exceed 4,000 rpm except in an emergency.y Do not drive at one constant engine or vehicle
speed for a long time, either fast or slow. y Avoid starting suddenly and rapid acceleration, ex-
cept in an emergency. y Avoid hard braking, except in an emergency.
The same break-in procedures should be applied to a
newly installed or overhauled engine or when brake
pads or brake linings are replaced with new ones.
Fuel economy hints
The following suggestions will help to save your fuel. y Select the proper gear position for the speed and
road conditions. y Avoid sudden acceleration or deceleration. Always
accelerate gently until you reach the desired speed.
Then try to maintain that speed for as long as possible. y Do not pump the accelerator and avoid racing the
engine. y Avoid unnecessary engine idling.
y Keep the engine properly tuned.
y Keep the tires inflated to the correct pressure shown
on the tire placard, which is located under the door
latch on the driver’s side. Low pressure will increase
tire wear and fuel consumption.y Use the air conditioner only when necessary.
y Keep the front and rear wheels in proper alignment.
y Avoid carrying unnecessary luggage or cargo.

Driving tips
y
Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads.y Do not drive or park over or near flammable materi-
als such as dry grass or fallen leaves, as they may
burn easily. The exhaust system is very hot while the
engine is running and right after engine stops. This
could create a fire hazard. y After driving through tall grass, mud, rocks, sand,
rivers, etc., check that there is no grass, bush, paper,
rags, stones, sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from the under-
body. If the vehicle is used with these materials
trapped or adhering to the underbody, a mechanical
breakdown or fire could occur.y Secure all cargo carried inside the vehicle and make
certain that it is not piled higher than the seatbacks.
During sudden stops or jolts, unsecured cargo could
be thrown around in the vehicle and cause injury. Do
not pile heavy loads on the roof. Those loads raise the
vehicle’s center of gravity and make it more prone totip over. y If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and move
the selector lever back and forth between “D” and “R” repeatedly. Do not race the engine. For the best pos-
sible traction, avoid spinning the wheels when trying to
free the vehicle. y
When the road surface is extremely slippery, you
can obtain better traction by starting the vehicle with
the transmission in 2nd than 1st (both for MT and AT). y Never equip your vehicle with tires larger than those
specified in this manual. y Wash the vehicle’s underbody after off-road driving.
Suspension components are particularly prone to dirt
buildup, so they need to be washed thoroughly.y Frequent driving of an AWD vehicle under hard-driv-
ing conditions such as rough roads or off roads will ne-
cessitate more frequent replacement of engine oil,
brake fluid and transmission oil than that specified in
the maintenance schedule described in the “Warranty
and Maintenance Booklet”.
Remember that damage done to your SUBARU while
operating it off-road and not using common sense pre-
cautions such as those listed above is not eligible for
warranty coverage.

Depress the pedal with a force of approximately 66 lbs
(294 N, 30 kg) and measure the distance between the
upper surface of the pedal pad and the floor.
When the measurement is smaller than the specifica-
tion, or when the pedal does not operate smoothly,
contact with your SUBARU dealer. Clutch pedal (Manual transmission
vehicles)
Check the clutch pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. „
Checking the clutch function
Check the clutch engagement and disengagement.
1. With the engine idling, check that there are no ab-
normal noises when the clutch pedal is depressed,
and that shifting into 1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal slowly to
check that the engine and transmission smoothly cou-
ple without any sign of slippage.
