2007 SUBARU IMPREZA WRX transmission

8-26Driving tips
safety’s sake, you should employ
extra caution when towing a
trailer and you should never
speed. You should also keep the
following tips in mind:
! Before starting out on a trip
. Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. . Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable. . Check that the tire pressures are
correct.. Check that the vehicle and trailer are
connected properly. Confirm that
–the trailer tongue is connected
properly to the hitch ball. – the trailer lights connector is con-
nected properly and trailer ’s brake
lights illuminate when the vehicle ’s
brake pedal is pressed, and that the trailer ’s turn signal lights flash when
the vehicle ’s turn signal lever is oper-
ated. –
the safety chains are connected
properly. – all cargo in the trailer is secured
safely in position.– the side mirrors provide a good
rearward field of view without a sig-
nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. ! Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss ofcontrol. . Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate engine revolution. . Avoid uneven steering, sharp turns and
rapid lane changes.. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit yourvehicle. .
Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down
immediately but gradually. . When passing other vehicles, consid-
erable distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.
1) Left turn
2) Right turn
. Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right

for a right turn. .If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed
immediately by the nearest SUBARU
dealer. ! Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
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. . When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. . 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
conditioner and stop the vehicle at the
nearest safe place. Refer to the “Engine
overheating ”section in chapter 9, and
“ Warning and indicator lights ”section in
chapter 3. .
If your vehicle has an automatic trans-
mission, 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. . If your vehicle has an automatic trans-
mission, place the selector lever as follows:
Uphill slopes: “D ”position
Downhill slopes: A low-speed gear posi-
tion to use engine braking ! Parking on a grade
Always block the wheels under both
vehicle 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
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply 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. Driving tips

9-4In 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 safeplace. &Changing a flat tire
WARNING
. Do not jack up the vehicle on an
incline or a loose road surface.
The jack can come out of the
jacking point or sink into the
ground and this can result in a
severe accident.
. Use only the jack provided with
your vehicle. The jack supplied
with the vehicle is designed only
for changing a tire. Never get
under the vehicle while support-
ing the vehicle with this jack. .
Always turn off the engine before
raising the flat tire 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 severeaccident.
1. Park on a hard, level surface, when-
ever possible, then stop the engine.
2. Set the parking brake securely and
shift a manual transmission vehicle in
reverse or an automatic transmission
vehicle 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.

2) Jack handle
3) Spare tire

apply excessive lateral load to the
towing hook.
Tie-down hooks:
1) Tie-down hook
2) Towing and tie-down hook
CAUTION
. Use only the specified towing
hook and tie-down hook. Never
use suspension parts or other
parts of the body for towing or
tie-down purposes.
. Never use the tie-down hook on
the underside of the vehicle
closest to the muffler for towingpurposes.
& Using a flat-bed truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the selector lever into the “P ”
position for automatic transmission vehi- cles 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.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), be careful not to scrape
them when placing the vehicle on
the carrier and when removing the
vehicle from the carrier. In case of emergency

9-14In case of emergency
&Towing with all wheels on the ground
1. Check the transmission and differen-
tial 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.
3. The ignition switch should be in the “Acc ”position while the vehicle is being
towed.
4. Take up slack in the towline slowly to
prevent damage to the vehicle.
WARNING
. Never turn the ignition switch to
the “LOCK ”position while the
vehicle is being towed because the steering wheel and the direc-
tion of the wheels will be locked.
. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION
. If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
. Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the
engine running.
. For vehicles with automatic
transmission, 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. Rear gate
–if the rear gate
cannot be unlocked
In the event that you cannot unlock the
rear gate by operating the power door
locking switches or the remote keyless
entry system, you can unlock it from inside
the cargo area.
1. Remove the access cover at the
bottom-center of the rear gate trim.
2. Locate the rear gate lock release lever
behind the rear gate trim panel.
