automatic SUBARU TRIBECA 2006 1.G Service Manual

7-8 Starting and operating
Stopping the engine
The ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
Automatic transmission
The automatic transmission is electroni-
cally controlled and provides 5 forward
speeds and 1 reverse speed. Also, it has
a manual mode and a SPORT mode.
NOTE yWhen the engine coolant tempera-
ture is still low, your vehicle’s automat-
ic transmission will up-shift at higher
engine speeds than when the coolant
temperature is sufficiently high in or-
der to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor-
mal timing after the engine has warmed
up.y Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
which the on-board computer has col-
lected and stored in memory to allow
Do not stop the engine when the ve-
hicle is moving. This will cause loss
of power to the power steering and
the brake booster, making steering
and braking more difficult. It could
also result in accidental activation
of the “LOCK” position on the igni-
tion switch, causing the steering
wheel to lock.
Do not shift from the “P” or “N” po-
sition into the “D” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle to
jump forward or backward. y Shift into the “P” or “R” position
only after the vehicle is complete-
ly stopped. Shifting while the ve-
hicle is moving may cause dam-
age to the transmission.
y Do not race the engine for more
than five seconds in any position
except the “N” or “P” position
when the brake is set or when
chocks are used in the wheels.
This may cause the automatic
transmission fluid to overheat.
yAvoid shifting from one of the for-
ward driving positions into the
“R” position or vice versa until the
vehicle has completely stopped.
Such shifting may cause damage
to the transmission.
y When parking the vehicle, first se-
curely apply the parking brake
and then place the selector lever
in the “P” position. Avoid parking
for a long time with the selector le-
ver in any other position as doing
so could result in a dead battery.

7-10 Starting and operating
TD (Drive)
This position is for normal driving.
The transmission automatically shifts into
a suitable gear from 1st to 5th according to
the vehicle speed and the acceleration
you require.
When more acceleration is required in this
position, press the accelerator pedal fully
to the floor and hold that position. The
transmission will automatically downshift
to 4th, 3rd, 2nd or 1st gear. When you re-
lease the pedal, the transmission will re-
turn to the original gear position.
To use the SPORT mode, move the lever
from this position into the manual gate.
To use the manual mode, move the lever
from this position into the manual gate
then move it toward the “+” and “–” ends. V While climbing a grade
When driving up a hill, undesired upshift to
4th or 5th gear is prevented from taking
place when the accelerator is released.
This minimizes the chance of subsequent downshifting to a lower gear when accel-
erating again. This prevents repeated up-
shifting and downshifting resulting in a
smoother operation of the vehicle.
NOTE
The transmission may downshift to
2nd or 1st gear, depending on the way
the accelerator pedal is pressed to ac-
celerate the vehicle again. V
While going down a hill
When you are descending a hill or any
other slope while braking with the “SPORT” mode selected, the transmis-
sion may downshift to 4th or 3rd gear de-
pending on how hard you depress the
brake pedal, causing engine braking to
work. Reacceleration for a short time will
cause the transmission to upshift normal- ly.
NOTE y A 5th-to-4th automatic downshift will
not occur at speeds above 78 mph (126
km/h) and a 4th-to-3rd automatic down-
shift will not occur at speeds above 53
mph (86 km/h).y Automatic downshifts to 4th or 3rd
may occur even when driving on a level
road depending on conditions, such as
how hard you depress the brake pedal. „
Selector lever reverse inhibit-
ing function
This function prevents accidental move-
ment of the selector lever to the “R” posi-
tion while the vehicle is moving.
The function becomes operational when
the vehicle reaches a speed of approxi-
mately 6 mph (10 km/h). Once operation-
al, it prevents the selector lever from being
moved from the “N” position to the “R” po-
sition. When the vehicle speed drops be-
low 6 mph (10 km/h), the function is can-
celed. The selector lever can then be
moved to the “R” and “P” positions.
When the ignition switch has been turned
to the “OFF” position, movement of the se-
lector lever from the “N” position to the “R”
position is possible for a limited time peri-
od and then becomes impossible. Also,
the selector lever cannot be moved to the
“R” position when it has been placed in the
“P” position and then placed again in the
“N” position. When movement of the se-
lector lever from the “N” position to the “R”
position has become impossible, turn the
ignition switch back to the “ON” position
then move the selector lever to the “P” po-
sition. Pressing the selector lever release
button also makes it possible to move the
selector lever to the “P” position at this
time.
Do not drive the vehicle with the se-
lector lever in the “N” (neutral) posi-
tion. Engine braking has no effect in
this condition and the risk of an ac-
cident is consequently increased.

7-12 Starting and operating
Gearshifts can be performed using the se-
lector lever.
Shift to the next-higher gear by briefly
pushing the selector lever toward the “+”
end of the manual gate.
Shift to the next-lower gear by briefly pull-
ing the selector lever toward the “–” end of
the manual gate.
NOTE
Please read the following points care-
fully and bear them in mind when usingthe manual mode. yWhen the temperature of the engine
oil is higher than normal, warning
beeps are emitted and the shift posi-
tion indicator shows “–”. If these warn-
ings are issued, deselect the manual
mode to protect the engine from dam- age. y
The transmission does not automati-
cally shift up in the manual mode. Per-
form gearshifts in accordance with
road conditions so that the tachometer
needle does not enter the red zone. If
the engine speed reaches a predeter-
mined level, a fuel-cut function will op-
erate. Shift up if this happens. Also, the
transmission may automatically shift
up to protect the engine. y If you attempt to shift down when the
engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible. y If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond. y You can perform a skip-shift (for ex-
ample, from 4th to 2nd) by operating
the selector lever twice in rapid suc-
cession. y The transmission automatically se-
lects 1st gear when the vehicle stops
moving. y If the temperature of the automatic
transmission fluid becomes too high,
the “AT OIL TEMP” warning light will
come on and upshifts to 5th gear will
not be possible. Immediately stop the vehicle in a safe place and let the en-
gine idle until the warning light goes off.
„ Maximum speeds
The following tables show the maximum
speeds that are possible with each differ- ent gear.
When down shifting, it is important to con-
firm that the current vehicle speed is not in
excess of the Maximum Allowable Speed
700309
When down shifting, ensure that the
vehicle is not travelling at a speed
exceeding the Maximum Allowable
Speed for the gear which is about to
be selected. Failure to observe this
precaution can lead to engine over-
revving and this in turn can result in
engine damage.
In addition, sudden application of
engine braking caused by down
shifting when the vehicle is travel-
ling on a slippery surface can lead to
wheel locking; as a consequence,
control of the vehicle may be lost
and the risk of an accident in-
creased.

of the gear which is about to be selected.
Never exceed posted speed limits.
NOTE y In order to prevent over-revving dur-
ing acceleration of the vehicle, the
transmission will automatically shift to
the next highest gear if the Maximum
Allowable Speed for the current gear is
exceeded.y Similarly, in order to prevent over-
revving during deceleration of the vehi-
cle, the transmission will remain in the
current gear if the speed of the vehicle
is in excess of the Maximum Allowable
Speed for the gear to which the selec-
tor lever has been moved. „ Driving tips
y On a road surface where there is a risk
of wheelspin (for example, a snow- or
gravel-covered road), you can pull away
from a standstill safely and easily by first selecting the 2nd gear of the manual mode. y
Always apply the foot or parking brake
when the vehicle is stopped in the “D” or
“R” position. y Always set the parking brake when
parking your vehicle. Do not hold the vehi-
cle with only the transmission. y Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D” position. Use the brake instead. y 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
problem. y A slight reduction in output torque may
occur before the engine warms up. „
SPORT mode
SPORT mode is used when power is
needed for rapid acceleration or for uphill
driving. To select this mode, move the se-
lector lever from the “D” position to the
manual gate.

The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. This helps prevent the loss of steering
control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h). „
ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound ofABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition. „
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately twoseconds.
This is an indication that the ABS system
is working properly.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal. y The warning light comes on right af-
ter the engine is started but goes out
immediately, remaining off. y The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h). y The warning light comes on during
driving, but it goes out immediately
and remains off.
When driving with an insufficient battery
y
When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the op-
eration of the ABS system.
If the warning light behaves as fol-
lows, the ABS system may not be
working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.

yThe warning light does not come
on when the ignition switch is
turned to the “ON” position.
y The warning light comes on when
the ignition switch is turned to the
“ON” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12 km/h).
y The warning light comes on dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.

7-28 Starting and operating
The vehicle will maintain the desired
speed.
Vehicle speed can be temporarily in-
creased while driving with the cruise con-
trol activated. Simply depress the acceler-
ator pedal to accelerate the vehicle. When
the accelerator pedal is released, the ve-
hicle will return to and maintain the previ-
ous cruising speed. „To temporarily cancel the
cruise control
There are three ways to cancel the cruise
control temporarily: y Pull the control lever in the “CANCEL”
direction. y Depress the brake pedal. y
Shift the selector lever into the “N” posi-
tion.
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.

Recommended winter (snow) tire size
P255/55R18 stud less
„ Tire chains
Driving on snowy grades or icy roads may
require the use of tire chains, in which
case put genuine SUBARU spring chains
on the front wheels only. Genuine
SUBARU spring chains are available from
your SUBARU dealer. These chains can
be installed on “all season tires” as origi-
nal equipment. Never install them on win- ter (snow) tires.
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 vehicle 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.
Refer to the “Automatic transmission” sec-
tion in chapter 7 for information on holding
the transmission in 2nd position.
Loading your vehicle
Tire chains cannot be used on tires
listed in the following because of
lack of clearance between the tires
and vehicle body.
All model: P255/55R 18 winter (snow) tires
Never allow passengers to ride on a
folded rear seatback or in the cargo
area. Doing so may result 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.

Driving tips 8-25
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 and AT OIL TEMP warning light
since the engine and transmission are rel-
atively prone to overheating under these
conditions. 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
The temperature of engine coolant is
less likely to rise to the OVERHEAT
zone in the “D” position than in the
manual mode position. y Avoid using the accelerator pedal to
stay stationary on an uphill slope instead
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 “P” and shut off the engine.

10-2 Appearance care
Appearance careExterior care „WashingNOTE
When having your vehicle washed in
an automatic car wash, make sure be-
forehand that the car wash is of suit-
able type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the ve-
hicle at least once a month to avoid con-
tamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required.
If you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowed
to dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft cloth. TWashing the underbody
Chemicals, salts and gravel used for deic-
ing road surfaces are extremely corrosive,
accelerating the corrosion of underbody components, such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders, and suspension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-sion.
After driving off-road or muddy or sandy
roads, wash the mud and sand off the un-
derbody.
Carefully flush the suspension and axle
parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
NOTE
Be careful not to damage brake hoses,
sensor harnesses, and other parts
when washing suspension compo-
nents. T
Using a warm water washer
y Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle. y Do not wash the same area continuous-
ly. y If a stain will not come out easily, wash
by hand. Some warm water washers are
y
When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes, drive
the vehicle at a safe speed while
lightly pressing the brake pedal to
heat up the brakes.
y Do not wash the engine compart-
ment and areas adjacent to it. If
water enters the engine air intake,
electrical parts or the power steer-
ing fluid reservoir, it will cause en-
gine trouble or faulty power steer-
ing respectively.
y Since your vehicle is equipped
with a rear wiper, automatic car-
wash brushes could become tan-
gled around it, damaging the wip-
er arm and other components.
Ask the automatic car-wash oper-
ator not to let the brushes touch
the wiper arm or to fix the wiper
arm on the rear window glass with
adhesive tape before operating
the machine.
