rear differential lock
234) 235)
236)
237) 238)
WARNING
234)If the “4L” or “4H” position (Easy
Select 4WD), “4LLc” or “4HLc” position
(Super Select 4WD II) is selected along
with the rear differential lock, the following
phenomena appear and it is very
dangerous. Please be sure to release the
rear differential lock on normal roads.
235)If the rear differential lock is used by
mistake when driving on a paved road:
With the rear differential lock on, the power
to drive the vehicle straight ahead
becomes very strong, which may make it
difficult to turn the steering wheel.
236)If the rear differential lock is used by
mistake when turning a curve or making a
right or left turn at a crossing or the like:
The vehicle is unable to make a turn and
may go straight ahead.237)If the rear differential lock is used by
mistake except when making an
emergency escape on snow or frozen
road: It becomes difficult to make a steady
turn.
238)In the case where the condition of the
road is different for the right tyre to drive
from the left tyre (such as one tyre on a
paved road and the other on ice), direction
of the vehicle may change abruptly when
engine braking or accelerating. Do not use
the rear differential lock except when
making an emergency escape on a snow
or frozen road, but drive with 4WD.
IMPORTANT
141)Operate the rear differential switch
after the wheels are stopped. Operating the
switch with the wheels turning may cause
the vehicle to dart in unexpected directions.
142)If a problem is detected in the rear
differential lock system, a safety device will
activate. The rear differential lock indicator
lamp will blink rapidly (twice per second),
and the rear differential lock will deactivate.
Park your vehicle in a safe place, turn off
the engine for a few moments. Restart the
engine. It is safe to continue driving if the
lamps resume normal operation. If the rear
differential lock indicator lamp blinks when
the rear differential lock is reactivated, have
the vehicle checked by a Fiat Dealership as
soon as possible.

STARTING AND DRIVING

1 – Check depths of a stream and
geographical features before attempting
to cross a stream and ford the stream
where the water is as shallow as
practicable.
2 – Set the drive mode-selector to “4L”
position (Easy Select 4WD), “4LLc”
position (Super Select 4WD II).
3 – Drive slowly at a speed of
approximately 5 km/h to avoid
splashing too much water.
148) 149)
Inspection and maintenance
following rough road operation
After operating the vehicle in rough road
conditions, be sure to perform the
following inspection and maintenance
procedures:
Check that the vehicle has not been
damaged by rocks, gravel, etc.
Carefully wash the vehicle with water.
Drive the vehicle slowly while lightly
depressing the brake pedal in order to
dry out the brakes. If the brakes still do
not function properly, contact a Fiat
Dealership as soon as possible to have
the brakes checked.
Remove the insects, dried grass, etc.
clogging the radiator core and the A/T
oil cooler.
After crossing a stream, be sure to have
the following items inspected at a Fiat
Dealership and take the necessary
measures:
Check the brake system and, if
necessary, have it serviced.
Check the engine, transmission,
transfer, and differential oil or grease
level and turbidity. If the oil or grease is
milky, it indicates water contamination.
Replace it with new oil or grease.
Grease the propeller shaft.
Check the inside of the vehicle. If
ingress of water is found, dry the carpet
etc.
Inspect the headlamps. If the
headlamp bulb is flooded with water,
have the headlamp drained off.
IMPORTANT
144)Selecting “4H” or “4L” position (Easy
Select 4WD), “4HLc” or “4LLc” position
(Super Select 4WD II) to drive on dry paved
road will increase the fuel consumption with
possible noise generation and early tyre
wear. It may also 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.
145)Avoid sudden braking, sudden
acceleration, and sharp turning; such
operations could cause skidding and
spinouts.146)Do not force the vehicle or drive
recklessly on sandy surfaces. In
comparison with normal road surfaces, the
engine and other drive-system components
are put under excessive strain when driving
on such a surface, and this could lead to
accidents.
147)If any of following conditions occur
while the vehicle is being driven,
immediately park your vehicle in a safe
place and follow these procedures: the
needle in the temperature gauge
approaches the overheating zone. Refer to
“Engine overheating”; automatic
transmission fluid temperature warning
lamp comes on. Refer to “When the A/T
(automatic transmission) fluid temperature
warning lamp comes on”.
148)Never cross a stream where the water
is deep. Do not change gears while
crossing the stream. Frequent crossing of
streams can adversely affect the life span
of the vehicle; we recommend you to take
the necessary measures to prepare,
inspect, and repair the vehicle.
149)After crossing a stream, apply the
brakes to be sure they are functioning
properly. If the brakes are wet and not
functioning properly, dry them out by
driving slowly while lightly depressing the
brake pedal. Inspect each part of the
vehicle carefully.
183

WARNING
239)When attempting to rock your vehicle
out of a stuck position, be sure that the
area around the vehicle is clear of people
and physical objects. The rocking motion
may cause the vehicle to suddenly launch
forward or backward, causing injury or
damage to nearby people or objects.
240)Go straight up. Do not try to traverse
across a steep slope.
241)If you begin to lose traction, ease off
the accelerator pedal and gently turn the
steering wheel alternatively left and right to
regain adequate traction again.
242)Avoid snaking down a sharp grade.
Descend the grade as straight as possible.
CAUTIONS ON
HANDLING OF
4 WHEEL DRIVE
VEHICLES
Tyres and wheels
Since the driving torque can be applied
to the 4 wheels, the performance of the
vehicle when operating in 4-wheel drive
is greatly affected by the condition of
the tyres.
Pay close attention to the tyres.
Install specified tyres on all wheels.
Refer to “Tyres and wheels”.
Be sure to the appropriate tyre
inflation pressure according to no cargo
or cargo. Refer to “Tyre inflation
pressures”.
Be sure to fit all 4 tyres and wheels of
the same size and type. When
replacement of any of the tyres or
wheels is necessary, replace all of them.
All tyres should be rotated whenever
the wear difference between the front
and rear tyres is recognizable.
Good vehicle performance cannot be
expected if there is a difference in wear
between tyres. Refer to “Tyre rotation”.
Check the tyre inflation pressure
regularly.
150)
Towing
If towing is necessary, we recommend
you to have it done by a Fiat Dealership
or a commercial tow truck service. In
the following cases, transport the
vehicle using a tow truck.
The engine runs but the vehicle does
not move or abnormal noise is
produced.
Inspection of the vehicle’s underside
reveals that oil or some other fluid is
leaking.
If a wheel gets stuck in a ditch, do not
try to tow the vehicle. Please contact
your Fiat Dealership or a commercial
tow truck service for assistance.
Only when you cannot receive a towing
service from a Fiat Dealership or
commercial tow truck service, tow your
vehicle carefully in accordance with the
instructions given in “Towing”.
NOTE The regulations concerning
towing may differ from country to
country. It is recommended that you
obey the regulations of the area where
you are driving your vehicle.
184
STARTING AND DRIVING

151)
Jacking up a 4-wheel drive vehicles
243)
Clutch operation
Quick or slight clutch engagement
made while the engine is running at
high speed will cause damage to the
clutch and transmission because the
tractive force is very great. Operate the
pedal slowly and positively.
IMPORTANT
150)Always use tyres of the same size,
same type, and same brand which have no
wear differences. Using the tyres which
differ in size, type, brands or the degree of
wear or the inappropriate tyre inflation
pressure, will 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.
151)Transport the vehicle with the driving
wheels on a carriage (Type C or D) as
illustrated. Never try to tow with the front or
rear wheels on the ground (Type A or B) as
illustrated. This could result in damage to
the drivetrain, or unstable towing.
WARNING
243)Do not crank the engine while jacking
up the vehicle. The tyre on the ground may
turn and the vehicle may roll off the jack.
BRAKING SYSTEM
All the parts of the brake system are
critical to safety. We recommend you to
have the vehicle checked at regular
intervals according to the service
booklet.
244)
Brake system
The service brake is divided into two
brake circuits. And your vehicle is
equipped with power brakes. If one
brake circuit fails, the other is available
to stop the vehicle. If your vehicle
should lose the power assist for some
reason, the brakes will still work.
In these situations even if the brake
pedal moves down to the very end of
its possible stroke or resists being
depressed, keep depressing the brake
pedal down harder and further than
usual; stop driving as soon as possible
and have the brake system repaired.
245) 246)
Warning lamp
The brake warning lamp illuminates to
indicate a fault in the braking system.
Refer to “Brake warning lamp”.
When brakes are wet
Check the brake system while driving at
a low speed immediately after starting,
especially when the brakes are wet, to
confirm they work normally.
288AHE100182
185

A film of water can be formed on the
brake discs or brake drums and
prevent normal braking after driving in
heavy rain or through large puddles, or
after the vehicle is washed. If this
occurs, dry the brakes out by driving
slowly while lightly depressing the brake
pedal.
When driving downhill
It is important to take advantage of the
engine braking by shifting to a lower
shift position while driving on steep
downhill roads in order to prevent the
brakes from overheating.
247)
Brake pads and linings
Avoid hard braking situations. New
brakes need to be broken-in by
moderate use for the first 200 km.
The disc brakes are provided with a
warning device which emits a shrieking
metallic sound while braking if the brake
pads have reached their wear limit. If
you hear this sound, have the brake
pads replaced.
248) 249)
WARNING
244)Avoid driving habits that cause heavy
braking as it causes brake overheating and
fade.245)Do not turn off the engine while your
vehicle is in motion. If you turn off the
engine while driving, the power assistance
for the braking system will stop working
and your brakes will not work effectively.
246)If the power assist is lost or if either
brake hydraulic system stops working
properly, have your vehicle checked
immediately by an Authorized Dealership.
247)Do not leave any objects near the
brake pedal or let a floor mat slide under it;
doing so could prevent the full pedal stroke
that would be necessary in an emergency.
Make sure that the pedal can be operated
freely at all times. Make sure the floor mat
is securely held in place.
248)Driving with worn brake pads will
make it harder to stop, and can cause an
accident.
249)If the power assist is lost or if either
brake hydraulic system stops working
properly, have your vehicle checked
immediately.
CRUISE CONTROL
(where provided)
Cruise control is an automatic speed
control system that keeps a set speed.
It can be activated at approximately
40 km/h or more.
250) 251)
152) 153) 154)
NOTE Cruise control may not be able
to keep your speed on uphills or
downhills. Your speed may decrease on
a steep uphill. You may use the
accelerator pedal if you want to stay at
your set speed. Your speed may
increase to more than the set speed on
a steep downhill. You have to use the
brake to control your speed. As a
result, the set speed driving is
deactivated.

by the condition described in “To
deactivate”, you can resume the
previously set speed by push up the
RES + switch (C) while driving at a
speed of approximately 40 km/h or
higher.
Type 1
Type 2Under either of the following conditions,
however, using the switch does not
allow you to resume the previously set
speed. In these situations, repeat the
speed setting procedure:
The CRUISE CONTROL ON/OFF
switch is pressed.
The ignition switch is turned OFF or
the operation mode is put in OFF.
Indicator lamp go off.
WARNING
250)If the device is faulty, turn ring nut A to
O, check the condition of the fuse and
contact a Fiat Dealership.
251)When travelling with the device active,
never move the gear lever to neutral.
252)On vehicles equipped with A/T,
although the set speed driving will be
deactivated when shifting to the “N”
(NEUTRAL) position, never move the
selector lever to the “N” (NEUTRAL)
position while driving. You would have no
engine braking and could cause a serious
accident.
IMPORTANT
152)When you do not wish to drive at a
set speed, turn off the cruise control for
safety.
153)On vehicles with M/T, do not move the
gearshift lever to the “N” (Neutral) position
while driving at a set speed without
depressing the clutch pedal. The engine will
run too fast and might be damaged.
154)Do not use cruise control when driving
conditions will not allow you to stay at the
same speed, such as in heavy traffic or on
roads that are winding, icy, snow-covered,
wet, slippery, on a steep downhill slope.
155)When the set speed driving is
deactivated automatically in any situation
other than those listed above, there may be
a system malfunction. Press the CRUISE
CONTROL ON/OFF switch to turn off the
cruise control and have your vehicle
inspected by a Fiat Dealership.

255)
To resume
The Speed Limiter memorizes the set
speed when system has been
deactivated, the Speed Limiter can
resume by push up the RES(C).Type 1
Type 2
However, the Speed Limiter
immediately starts controlling and the
vehicle decreases as if an accelerator
pedal is closed fully, when the vehicle
speed is higher than the set speed.
256)
IMPORTANT
156)Because the system does not use
service brake (hydraulic brake), the vehicle
speed may exceed the set speed on the
downhill.
WARNING
253)There is a possibility for the Speed
Limiter to allow abrupt acceleration
corresponding to accelerator pedal
position. So be careful of the abrupt
acceleration.
254)Be careful about over speed.
255)There is a possibility for the Speed
Limiter to allow abrupt acceleration
corresponding to accelerator pedal
position when the Speed Limiter is
deactivated. Be careful.
256)There is a possibility to occur jerk,
depending on a running resistance. Be
careful.
