The 2WD/4WD operation indicator
lamp will blink during shifting process
from “4H” to “4L” or vice versa, as the
transfer passes through the neutral
position. Be sure to operate the drivemode-selector until the 2WD/4WD
operation indicator lamp illuminates
again.
When parking, apply the parking brake
before stopping the engine and make
sure that the 2WD/4WD operation
indicator and the low range lamp are
not blinking during shifting process
between “4H” <–> “4L”. Otherwise, the
vehicle could unexpectedly move even
if the automatic transmission is in the
“P” (PARK) position.
If, after a “4H” <–> “4L” selection has
been made, the 2WD/4WD operation
indicator continues blinking and the
desired range is not actually selected,
return the drive mode selector to its
previous position. Place the steering
wheel in the straight ahead position,
drive the vehicle forward, and release
the accelerator pedal. Next, hold down
the clutch pedal (with manual
transmission) or place the selector lever
in the “N” (NEUTRAL) position (with
automatic transmission) and make the
range selection again.
If the low range lamp blinks when you
attempt to make a “4H” <–> “4L”
selection, a “4H” <–> “4L” selection
cannot be made. Stop the vehicle and
release the accelerator pedal. Next,
hold down the clutch pedal (with
manual transmission) or place the
selector lever in the “N” (NEUTRAL)position (with automatic transmission)
and make the range selection again.

selected, this lamp goes out and
function again. Refer to “ESC indicator
lamp, ESC OFF indicator lamp”.
136)
IMPORTANT
133)The “4L” range gives maximum torque
for low-speed driving on steep slopes, as
well as sandy, muddy, and other difficult
surfaces. On vehicles with automatic
transmission, do not exceed speeds of
approximately 70 km/h in “4L” range.
134)Do not drive your vehicle in the “4H”
or “4L” on dry paved roads and highways.
Doing so may result in excessive tyre wear,
increased fuel consumption, and possible
noise generation. It may also increase the
differential oil temperature, which may
damage the drive system. Further, the drive
train will be subjected to excessive loading,
resulting in oil leakage, component seizure,
or other serious problems. On dry paved
roads and highways, drive the vehicle in
“2H” only.
135)Do not operate the drive
mode-selector while the rear wheels of the
vehicle are slipping on snow or ice.

136)If a problem is detected in the transfer
system, a safety device will activate. The
2WD/4WD operation indicator blinks (twice
per second), and transfer shifting will
become impossible. Park your vehicle in a
safe place, turn off the engine for a few
moments. Restart the engine. The lamp
should resume normal operation. If the
lamp continue to blink, have the vehicle
checked by a Fiat Dealership as soon as
possible.SUPER SELECT 4WD II
(where provided)
Shifting to rear-wheel drive or 4-wheel
drive can be made by operating the
drive mode-selector (A). Set the drive
mode-selector to an appropriate
position according to the road surface
conditions. In addition, the 2WD/4WD
operation indicator lamp and low-range
indicator lamp indicates the drive
mode-selector setting state. Refer to

IMPORTANT
137)The “4LLc” range gives maximum
torque for low-speed driving on steep
slopes, as well as sandy, muddy, and other
difficult surfaces. On vehicles with
automatic transmission, do not exceed
speeds of approximately 70 km/h in “4LLc”
range.
138)Do not drive your vehicle in the
“4HLc” or “4LLc” position on dry paved
roads and highways. Doing so may result in
excessive tyre wear, increased fuel
consumption, and possible noise
generation. It may also increase the
differential oil temperature, which may
damage the drive system. Further, the drive
train will be subjected to excessive loading,
resulting in oil leakage, component seizure,
or other serious problems. On dry paved
roads and highways, drive the vehicle in
“2H” or “4H” only.
139)Do not operate the drive
mode-selector while the rear wheels of the
vehicle are slipping on snow or ice.
140)If a problem is detected in the transfer
system, a safety device will activate. The
front and rear wheel lamps will go out, the
centre differential lock lamp will blink rapidly
(twice per second), and transfer shifting will
become impossible fig. 277. Park your
vehicle in a safe place, turn off the engine
for a few moments. Restart the engine. The
lamp should resume normal operation. If
the lamps continue to blink, have the
vehicle checked by a Fiat Dealership as
soon as possible.
REAR DIFFERENTIAL
LOCK
(where provided)
If one wheel starts to spin freely and the
vehicle becomes stuck and cannot be
freed even using 4-wheel drive, the rear
differential lock switch (A) can be used
to activate the rear differential lock for
extra traction.
Operating the rear differential lock
1. Bring the vehicle to a complete stop.
2. Move the drive mode-selector to
“4L” or “4H” position (Easy select
4WD), “4LLc” or “4HLc” position (Super
select 4WD II).
3. To activate the rear differential lock,
press the rear differential lock switch
(A).

pedal as constant as possible, and
drive at low speed.
146) 147)
239)
NOTE Avoid sudden braking,
acceleration, and turning; such
operations could result in the vehicle
becoming stuck.
NOTE If the vehicle becomes stuck in
sandy or muddy roads, it can often be
moved a rocking motion. Move the
selector lever rhythmically between the
“D” (DRIVE) and “R” (REVERSE)
position (with manual transmission,
between 1st and Reverse), while
applying slight pressure to the
accelerator pedal.
NOTE It is recommended to start the
vehicle with parking brake partially, but
not completely, applied by slightly
pulling the parking brake lever. After the
vehicle has become free, do not forget
to release the parking brake.
NOTE If it is necessary to drive in
extremely muddy conditions, the use of
tyre chains is recommended. Because
the extent of muddy conditions is
difficult to judge and the vehicle could
become bogged down very deeply,
operation should be at a low speed. If
possible, get out of the vehicle and
check the conditions ahead before
proceeding.NOTE Driving over roads in coastal
areas or roads on which anti-skid
preparations have been spread can
cause rust on the vehicle; wash the
vehicle thoroughly as soon as possible
after such use.
Climbing sharp grades
Set the drive mode-selector to “4L”
position (Easy Select 4WD), “4LLc”
position (Super Select 4WD II) to
maximize the engine torque.
240) 241)
NOTE Choose as smooth a slope as
possible with few stones or other
obstacles.
NOTE Before attempting to drive up
the slope, walk up it to confirm that the
vehicle can handle the grade.
Descending sharp grades
Set the drive mode-selector to “4L”
position (Easy Select 4WD), “4LLc”
position (Super Select 4WD II), use the
engine brake (downshifting) and
descend slowly.
242)
NOTE When descending a sharp
grade, if the brakes are applied
suddenly because of an obstacle
encountered, control of the vehicle
could be lost. Before descending the
slope, walk down it and confirm the
path.NOTE Before descending a grade, it is
necessary to choose the appropriate
gear. Avoid changing gears or
depressing the clutch while descending
the grade.
NOTE FCA is not responsible to the
operator for any damage or injury
caused or liability incurred by the
improper and negligent operation of a
vehicle. All techniques of vehicle
operation described herein depend on
the skill and experience of the operator
and other participating parties and any
deviation from the recommended
operation instructions above is at their
own risk.
Turning sharp corners
When turning a sharp corner in “4H” or
“4L” position (Easy Select 4WD),
“4HLc” or “4LLc” position (Super Select
4WD II) at low speed, a slight difference
in steering may be experienced similar
to as if the brakes were applied. This is
called tight corner braking and results
from each of the 4 tyres being at a
different distance from the corner.
Crossing a stream
4-wheel drive vehicles are not
necessarily waterproof. If the electrical
circuits become wet, further operation
of the vehicle will be impossible;
therefore, avoid crossing streams
unless absolutely necessary. If crossing
a stream is unavoidable, use the
following procedure:
182
STARTING AND DRIVING

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.

10. Tighten the nuts crisscross in 2 or
3 steps until each nut has been
tightened securely.
Tightening torque
Steel wheel: 137 to 157 Nm
Aluminium wheel: 118 to 137 Nm
(Achieved by applying a force at the
end of the wheel nut wrench supplied
with the vehicle. Steel wheel: 510 to
580 N; Aluminium wheel: 440 to 500 N)
322)
11. Lower the jack all the way and
remove it.
170) 171)
NOTE Occasionally when the vehicle is
jacked up, the grooved portion of the
designated point will not come off.
When this happens, rock the vehicle to
lower the ram.
If the jack is difficult to remove by hand,
insert the jack handle (M) into the
bracket (N). Then using the handle,
remove the jack.
12. Press the piston down all the way,
and turn the release valve clockwise as
far as possible.
13. Check your tyre inflation pressure.
The correct pressures are shown on the
door label. See the illustration.

NOTE Confirm that the hanger disc is
securely fitted in the wheel disc hole
when the wheel is just lifted off the
ground.
3. After winding up the spare wheel
sufficiently, make sure it is not loose (the
tightening torque should be
approximately 40 Nm (achieved by
applying a force of 200 N at the end of
the wheel nut wrench) then withdraw
the jack handle.
4. Have your damaged tyre repaired as
soon as possible.
327) 328) 329)
To store the tools, jack and jack
handle
Reverse the removing procedure when
storing the jack, jack handle and wheel
nut wrench. Refer to “Tools, jack and
jack handle”.
WARNING
302)It is extremely dangerous to attempt
to change a wheel on the side of the
vehicle next to the driving lane: make sure
that the vehicle is at a sufficient distance
from the road, to avoid being run over.
303)Use the jack only to replace wheels
on the vehicle with which it is supplied or
on other vehicles of the same model. Never
use the jack for other purposes, such as
lifting other car models. Never use the jack
to carry out repairs under the vehicle.
Incorrect positioning of the jack may cause
the lifted vehicle to fall. Do not use the jack
for loads higher than those shown on the
label.
304)Have the wheel repaired and refitted
as soon as possible. Do not apply grease
to the bolt threads before fitting: they could
come unscrewed.
305)The spare wheel supplied (for
versions/markets, where provided) is
specific for your vehicle. Therefore, it must
not be used on other models. Do not use
spare wheels of other models on your
vehicle. The wheel bolts are specific for
your vehicle: do not use them on different
models and do not use bolts from other
models on your car.
306)Use your hazard lights, warning
triangle, etc. to show that your vehicle is
stationary according to the regulations in
force. Passengers should get out of the
vehicle, particularly if it is heavily loaded,
and wait for the wheel to be changed away
from the traffic.Apply the handbrake. in the event of a
wheel change on a slope or on unsurfaced
roads, put any object as stop under the
wheels.
307)Be sure to apply chocks or blocks to
the correct tyre when jacking up the
vehicle. If the vehicle moves while jacked
up, the jack could slip out of position,
leading to an accident.
308)The pressure should be periodically
checked and maintained at the specified
pressure while the tyre is stowed. Driving
with an insufficient tyre pressure can lead
to an accident. If you have no choice but to
drive with an insufficient tyre pressure,
keep your speed down and inflate the tyre
to the correct pressure as soon as
possible. (Refer to “Tyre inflation
pressures”).
309)Set the jack only at the positions
shown here. If the jack is set at a wrong
position, it could dent your vehicle or the
jack might fall over and cause personal
injury.
310)Do not use the jack on a tilted or soft
surface. Otherwise, the jack might slip and
cause personal injury. Always use the jack
on a flat, hard surface. Before setting the
jack, make sure there are no sand or
pebbles under the jack base.
