steering FIAT FULLBACK 2016 1.G Service Manual

WARNING
281)If the vehicle is towed with the ignition
switch in the “ON” position or the operation
mode in ON and only the front wheels or
only the rear wheels raised off the ground,
the active traction control system may
operate, resulting in an accident.
282)If your vehicle equipped with the
Active Stability & Traction Control system
(ASTC), if the vehicle is towed with the
ignition switch in the “ON” position or the
operation mode in ON and only the front
wheels or only the rear wheels raised off
the ground, the active traction control
system may operate, resulting in an
accident.
283)Avoid sudden braking, acceleration
and steering wheel movements; such
driving operation could cause damage to
the towing hook or towing rope. People in
the vicinity could be injured as a result.284)When going down a long slope, the
brakes may overheat, reducing
effectiveness. Have your vehicle transport
by a tow truck.
285)The person in the vehicle being towed
must pay attention to the brake lamps of
the towing vehicle and make sure the rope
never becomes slack.
286)Do not use flexible cables for towing
and avoid jerking. During towing
operations, make sure that the fastened
joint does not damage adjoining
components.
287)When towing the vehicle comply with
the specific rules of the Highway Code
regarding the towing device and the
behaviour on the road.
288)Do not start the engine while towing
the vehicle.
289)Towing must be made exclusively on
roads/streets; the device must not be used
to recover the vehicle if it got off the road.
290)Towing must not be made for getting
past significant obstacles on the road (e.g.
heaps of snow or material on the road
surface).
291)Towing must take place with the two
vehicles (one towing, the other towed)
aligned as much as possible; towing by
roadside assistance vehicles, too, must
take place with the two vehicles aligned as
much as possible.
IMPORTANT
138)This vehicle must not be towed by a
tow truck using sling lift type equipment
(Type A) as illustrated. Using a sling lift will
damage the bumper and front end.
139)On 4WD vehicles, be sure to set the
drive mode-selector to “2H” position and
transport the vehicle with the driving wheels
on a carriage (Type D or E) as illustrated.
Never try to tow with the drive
mode-selector in “4H” or “4L” positions
(easy select 4WD), “4H”, “4HLc” or “4LLc”
positions (super select 4WD II) and with the
front or rear wheels on the ground (Type B
or C) as illustrated. This could result in the
driving system damage or vehicle may
jump at the carriage. If you cannot set the
drive mode-selector to “2H” position or the
transmission is malfunctioning or damaged,
transport the vehicle with the all wheels on
a carriage (Type D or E) as illustrated.
140)On 2WD vehicles, if the transmission
is malfunctioning or damaged, transport the
vehicle with the driving wheels on a
carriage (Type C, D or E) as illustrated.
141)If you tow the vehicles with automatic
transmission with the driving wheels on the
ground (Type B) as illustrated, make sure
that the towing speed and distance given
below are never exceeded, causing
damage to the transmission. Towing speed:
30 km/h Towing distance: 80 km For the
towing speed and the towing distance,
follow the local driving laws and
regulations.

142)Never tow an automatic transmission
vehicle with the front wheels up (and the
rear wheels on the ground) (Type B) when
the automatic transmission fluid level is low.
This may cause serious and expensive
damage to the transmission.
143)When the engine is not running, the
brake booster and power steering pump do
not operate. This means higher brake
depression force and higher steering effort
are required. Therefore, vehicle operation is
very difficult.
144)Do not leave the ignition switch in the
“LOCK” position or the operation mode in
OFF. The steering wheel will lock, causing
loss of control.
145)On vehicles with super select 4WD II,
when you are going to tow another vehicle,
set the drive mode-selector to “4H”
position. Selecting “2H” drive may increase
the differential oil temperature, resulting in
possible damage to the driving system.
Further, the drive train will be subjected to
excessive loading possibly leading to oil
leakage, component seizure, or other
serious faults.OPERATION UNDER
ADVERSE DRIVING
CONDITIONS
On a flooded road
Avoid flooded roads. Water could enter
the brake discs, resulting in temporarily
ineffective brakes. In such cases, lightly
depress the brake pedal to see if the
brakes operate properly. If they do not,
lightly depress the pedal several times
while driving in order to dry the brake
pads.
When driving in rain or on a road with
many puddles a layer of water may
form between the tyres and the road
surface. This reduces a tyre’s frictional
resistance on the road, resulting in loss
of steering stability and braking
capability.
To cope with this, observe the following
items:
(a) Drive your vehicle at a slow speed.
(b) Do not drive on worn tyres.
(c) Always maintain the specified tyre
inflation pressures.On a snow-covered or frozen road
When driving on a snow-covered or
frozen road, it is recommended that you
use snow tyres or snow traction device
(tyre chains). Refer to the “Snow tyres”
and “Snow traction device (tyre chains)”
sections.
Avoid high-speed operation, sudden
acceleration, abrupt brake application
and sharp cornering.
Depressing the brake pedal during
travel on snowy or icy roads may cause
tyre slippage and skidding. When
traction between the tyres and the road
is reduced the wheels may skid and the
vehicle cannot readily be brought to a
stop by conventional braking
techniques. Braking will differ,
depending upon whether you have
anti-lock brake system (ABS). If you do
have ABS, brake by pressing the brake
pedal hard, and keeping it pressed. If
you do not have ABS, pump the brake
pedal with short rapid jabs, each time
fully applying and fully releasing for
greatest effect.
Allow extra distance between your
vehicle and the vehicle in front of you,
and avoid sudden braking.
Accumulation of ice on the braking
system can cause the wheels to lock.
Pull away from a standstill slowly after
confirming safety around the vehicle.

IN CASE OF EMERGENCY

Fuse replacement
294) 295) 296) 297) 298)
147)
1. Before replacing a fuse, always turn
off the electrical circuit concerned and
place the ignition switch in the “LOCK”
position or put the operation mode in
OFF.
2. Remove the fuse puller (A) from the
inside of the fuse block in the engine
compartment.
3. Referring to the fuse load capacity
table, check the fuse pertaining to the
problem.B. Fuse is OK
C. Blown fuse
NOTE If any system does not function
but the fuse corresponding to that
system is normal, there may be a fault
in the system elsewhere. We
recommend you to have your vehicle
checked.
4. Insert a new fuse of the same
capacity by using the fuse puller into
the same place at the fuse block.
WARNING
294)If the newly inserted fuse blows again
after a short time, we recommend you to
have the electrical system checked to find
the cause and rectify it.
295)Never use a fuse with a larger
capacity than specified or a substitute
(such as a cable or foil). Doing so could
cause the circuit wires to overheat and
create a fire.
296)Never replace a blown fuse with metal
wires or other material.
297)Before replacing a fuse, make sure
that the ignition key has been removed and
that all the other services are switched off
and/or disengaged.
298)If a general protection fuse for safety
systems (airbag system, braking system),
power unit systems (engine system,
transmission system) or steering system
blows, contact a Fiat Dealership.
