2006 SUBARU LEGACY automatic transmission

7-38 Starting and operating
yDepress the clutch pedal (manual trans-
mission vehicles only). y Shift the selector leve r into the “N” posi-
tion (automatic transmission vehicles
only). y Shift the shift lever into neutral position
(manual transmission vehicles only).
The “ ” indicator light in the combina-
tion meter goes off when the cruise control
is cancelled. To resume the cruise control after it has
been temporarily canceled and with vehi-
cle speed of approximately 20 mph (32
km/h) or more, push the control lever up-
ward in the “RES/ACC” direction to return
to the original cruising speed automatical-ly.
The “ ” indicator light in the combina-
tion meter will automatically come on at
this time. „ To turn off the cruise control
There are two ways to turn off the cruise
control: y Push the main switch again.
y Turn the ignition switch to the “ACC” or
“LOCK” position (but only when the vehi-
cle is completely stopped). „
To change the cruising speed
T To increase the speed (by control le-
ver)
Push the control lever upward in the
“RES/ACC” direction and hold it until the
vehicle reaches the desired speed. Then,
release the control lever. The vehicle
speed at that moment will be memorized
and treated as the new set speed.
When the difference between the actual
vehicle speed and the set speed is less
than 4 mph (6.8 km/h), the set speed can
be increased 1 mph (1.6 km/h) each time
by pressing the control lever upward in the
“RES/ACC” direction quickly within 0.25 second. T
To increase the speed (by accelera-tor pedal)
1. Depress the accelerator pedal to accel-
erate the vehicle to the desired speed.
2. Push the control lever downward in the
“SET/COAST” direct ion once. Now the
desired speed is set and the vehicle will
keep running at that speed without de-
pressing the accelerator pedal.
NOTE
If the difference between the actual ve-
hicle speed when the control lever is
pushed downward and the speed last
time you set is less than 4 mph (6.8 km/
h), the vehicle speed will be lowered by
1 mph (1.6 km/h). This occurs because
the cruise control system unit regards
this lever operation as that intended to
decrease the vehicle speed.

squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the ru bber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes be-
cause they may damage the paint of the
vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing temper-
ature varies according to how much it is di-
luted, as indicated in the following table.
In order to prevent freezing of washer flu-
id, check the freezing temperatures in the
table above when adjusting the fluid con-
centration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside tem-
perature, it may freeze and block the noz-zles.
T
Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and dan-
gerous.
While warming up the vehicle before driv-
ing, check that the accelerator pedal,
brake pedal, and all other controls operatesmoothly.
Clear away ice and snow that has accu-
mulated under the fenders to avoid mak-
ing steering difficult. During severe winter
driving, stop when and where it is safe to do so and check under the fenders period-
ically. T
Parking in cold weather
Do not use the parking brake when park-
ing for long periods in cold weather since
it could freeze in that position. Instead, ob-
serve the following.
1. Place the shift lever in “1” or “R” for
manual transmission vehicles, and in “P”
for automatic trans mission vehicles.
2. Use tire stops under the tires to prevent
the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them.
When the vehicle has been left parked af-
ter use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the brake system, which could cause poor
braking action. Check for snow or ice

100% –49 °F (–45 °C)
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
inappropriate, sprayed washer fluid
may freeze on the windshield and
obstruct your view, and the fluid
may freeze in the reservoir tank.
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.

8-12 Driving tips
require the use of tire chains, in which
case put the chains on the front wheels
only. Use only SAE class S type chains
that are of the correct size for your tires so
as not to damage the vehicle body or sus-
pension.
When driving with tire chains, drive at
speeds below 19 mph (30 km/h). When a
temporary spare tire is on a front wheel,
replace the temporary spare tire with the
rear tire on the same side of the vehicle,
and then fit chains on the front tires.
Always use the utmost care when driving
with tire chains – overconfidence because
you are driving with tire chains could eas-
ily lead to a serious accident. „ Rocking the vehicle
If you must rock the ve hicle to free it from
snow, sand, or mud, depress the acceler-
ator pedal slightly and move the selector
lever back and forth between “D” and “R”
repeatedly. Do not race the engine. For
the best possible traction, avoid spinning
the wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
Refer to the “Automatic transmission – 4- speed” and “Automatic transmission – 5-
speed” section in chapter 7 for information
on holding the transmission in 2nd posi-
tion.Loading your vehicle
Never allow passengers to ride on a
folded rear seatback, in the trunk or
in the cargo area. Doing so may re-
sult in serious injury.
y
Never stack luggage or other car-
go higher than the top of the seat-
back because it could tumble for-
ward and injure passengers in the
event of a sudden stop or acci-
dent. Keep luggage or cargo low,
as close to the floor as possible.

sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts. yWhen driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3.
NOTE
With AT vehicles, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D” posi-
tion than in the manual mode position. y If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission fluid to overheat. T
Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-
sion) and shut off the engine.

In case of emergency 9-3
The temporary spare tire is smaller and
lighter than a conventional tire and is de-
signed for emergency use only. Remove
the temporary spare tire and re-install the
conventional tire as soon as possible be-
cause the spare tire is designed only for
temporary use.
Check the inflation pressure of the tempo-
rary spare tire periodically to keep the tire
ready for use. The correct pressure is 60
psi (420 kPa, 4.2 kgf/cm 2
).
When using the temporary spare tire, note
the following.y Do not exceed 50 mph (80 km/h).
y Do not put a tire chain on the temporary
spare tire. Because of the smaller tire
size, a tire chain will not fit properly. y Do not use two or more temporary
spare tires at the same time. y Do not drive over obstacles. This tire
has a smaller diameter, so road clearance
is reduced. 1) Tread wear indicator bar
2) Indicator location mark
y When the wear indicator appears on the
tread, replace the tire. y The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel.
NOTE
If your vehicle is an AWD type with an
automatic transmission but is neither a
Turbo model nor a 3.0-liter model, de-
activate its All-Wheel-Drive capability
as follows: Before driving your vehicle
with the temporary spare tire, put a
spare fuse inside the FWD connectorlocated in the engi ne compartment and
confirm that the “ ” warning
light comes on. The All-Wheel-Drive
capability of the vehicle has now been
deactivated. After re -installing the con-
ventional tire, remove the spare fuse
from the FWD connector in order to re-
activate All-Wheel Drive.
Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechani-
cal damage to the
drive train of your
vehicle.

9-4 In case of emergency
Flat tires
If you have a flat tire while driving, never
brake suddenly; keep driving straight
ahead while gradually reducing speed.
Then slowly pull off the road to a safe
place. „Changing a flat tire
1. Park on a hard, level surface, whenev-
er possible, then stop the engine.
2. Set the parking brake securely and
shift a manual transmission vehicle in re-
verse or an automatic transmission vehi-
cle in the “P” (Park) position.
3. Turn on the hazard warning flasher and
have everyone get out of the vehicle.
4. Put wheel blocks at the front and rear
of the tire diagonally opposite the flat tire. Sedan
1) Jack handle
2) Spare tire
3) Jack and tool bucket
y
Do not jack up the vehicle on an
incline or a loose road surface.
The jack can come out of the jack-
ing point or sink into the ground
and this can result in a severe ac-
cident.
yUse only the jack provided with
your vehicle. The jack supplied
with the vehicle is designed only
for changing a tire. Never get un-
der the vehicle while supporting
the vehicle with this jack.
yAlways turn off the engine before
raising the flat ti re off the ground
using the jack. Never swing or
push the vehicle supported with
the jack. The jack can come out of
the jacking point due to a jolt and
this can result in a severe acci-
dent.

„Using a flat-bed truck
This is the best way to transport your vehi-
cle. Use the following procedures to en-
sure safe transportation.
1. Shift the selector lever into the “P” po-
sition for automatic transmission vehicles
or “1st” for manual transmission vehicles. 2. Pull up the parking brake lever firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out. „
Towing with all wheels on the ground
1. Check the transmission and differential
oil levels and add oil to bring it to the upper
level if necessary.
2. Release the parking brake and put the
transmission in neutral.
Use the rear tie-down hooks only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip off
the hooks, possibly causing a dan-
gerous situation.

yNever turn the ignition switch to
the “LOCK” position while the ve-
hicle is being towed because the
steering wheel and the direction
of the wheels will be locked.
900254
yRemember that the brake booster
and power steering do not func-
tion when the engine is not run-
ning. Because the engine is
turned off, it will take greater ef-
fort to operate the brake pedal and
steering wheel.
y If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
y Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the en-
gine running.
y For vehicles with automatic trans-
mission, the traveling speed must
be limited to less than 20 mph (30
km/h) and the traveling distance
to less than 31 miles (50 km). For
greater speeds and distances,
transport your vehicle on a flat-
bed truck.
