ECU SUBARU CROSSTREK 2017 1.G Repair Manual

!Trailer lights
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’s electrical
system and cause a malfunction of
your vehicle’s lighting system.
Connection of trailer lights to your vehi-
cle’s electrical system requires modifica-
tions to the vehicle’s lighting circuit to
increase its capacity and accommodate
wiring changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals and the brake
lights each time you connect a trailer to
your vehicle.
!Tires
WARNING
Never tow a trailer when the tem-
porary spare tire is used. The tem-
porary spare tire is not designed to
sustain the towing load. Use of the
temporary spare tire when towing
can result in failure of the spare tire
and/or less stability of the vehicle.
Make sure that all the tires on your vehicleare properly inflated. Refer to“Tires”F12-
8.
Trailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer manufacturer’s
specifications. Also check federal, state,
province and/or other applicable regula-
tions.
In the event your vehicle gets a flat tire
when towing a trailer, ask a commercial
road service representative or profes-
sional to repair the flat tire.
If you carry a regular size spare tire in your
vehicle or trailer as a precaution against
getting a flat tire, be sure that the spare
tire is firmly secured.
&Trailer towing tips
CAUTION
.For models equipped with the
BSD (Blind Spot Detection) and
RCTA (Rear Cross Traffic Alert)
driving support systems, when
towing a trailer, press the BSD/
RCTA OFF switch to deactivate
the system. The system may not
operate properly due to the
blocked radar waves. For details
about the BSD/RCTA OFF switch,refer to“BSD/RCTA OFF switch”
F7-55.
.Never exceed 45 mph (72 km/h)
when towing a trailer in hilly
country on hot days.
.When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent when compared to normal
operation. For safety’s sake, you
should employ extra caution
when towing a trailer and you
should never drive at excessive
speeds. You should also keep the
following tips in mind:
.When parking on a steep slope
with a trailer attached to your
vehicle, the braking power of the
parking brake may not be suffi-
cient since stronger braking
power is needed.
!Before starting out on a trip
.Check the towing regulations for trailer
or caravan vehicles that vary by state/
region. Failure to comply with the proce-
dures set forth will not only compromise
your safety, but will also negate your
insurance coverage and/or may violate
the state road and traffic acts and regula-
tions.
Driving tips/Trailer towing
–CONTINUED–8-23

Driving tips/Trailer towing
.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 rests horizon-
tally 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 rating and 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 learnthe“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 of
control.
.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 your
vehicle.
.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 promptly begin
decelerating your vehicle at a gradual
pace..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 your nearest SUBARU
dealer.
