ECONOMICAL
DRIVING
For economical driving, there are some
technical requirements that have to be
met. The prerequisite for low fuel
consumption is a properly adjusted
engine. In order to achieve longer life of
the vehicle and the most economical
operation, we recommend you to have
the vehicle checked at regular intervals
in accordance with the service
standards.
Fuel economy and generation of
exhaust gas and noise are highly
influenced by personal driving habits as
well as the particular operating
conditions. The following points should
be observed in order to minimize wear
of brakes, tyres and engine as well as
to reduce environmental pollution.
Accelerating and decelerating
Drive according to traffic conditions,
and avoid sudden starts, sudden
acceleration, and sudden braking, as
they will increase fuel consumption.
Shifting
Shift only at an appropriate speed and
engine speed. Always use the highest
shift position possible.
The transfer shift lever or the drive
modeselector should be set to “2H”
when driving 4WD vehicles on normal
roads and express ways to obtain best
possible fuel economy.City traffic
Frequent starting and stopping
increases the average fuel
consumption. Use roads with smooth
traffic flow whenever possible. When
driving on congested roads, avoid use
of a low shift position at high engine
speeds.
Idling
The vehicle consumes fuel even during
idling. Avoid extended idling whenever
possible.
Speed
At higher the vehicle speed, more fuel is
consumed. Avoid driving at full speed.
Even a slight release of the accelerator
pedal will save a significant amount of
fuel.
Tyre inflation pressure
Check the tyre inflation pressures at
regular intervals. Low tyre inflation
pressure increases road resistance and
fuel consumption. In addition, low tyre
pressures adversely affect tyre wear
and driving stability.
Cargo loads
Do not drive with unnecessary articles
in the luggage compartment. Especially
during city driving where frequent
starting and stopping is necessary, the
increased weight of the vehicle will
greatly affect fuel consumption. Also
avoid driving with unnecessary luggage
or carriers, etc., on the roof; theincreased air resistance will increase
fuel consumption.
Cold engine starting
Starting of a cold engine consumes
more fuel. Unnecessary fuel
consumption is also caused by keeping
a hot engine running. After the engine is
started, commence driving as soon as
possible.
Cooler or air conditioning
The use of the air conditioner will
increase the fuel consumption.
146
STARTING AND DRIVING

NOTE In the following cases, the
“Start&Stop” indicator lamp will turn off
and the engine will not stop
automatically.
After the engine restarts
automatically, the vehicle speed has not
exceeded approximately 5 km/h.
After the engine start, approximately
30 seconds or more have not elapsed.
After the engine restarts
automatically, the vehicle stops again
within 10 seconds.
Engine coolant temperature is low.
Ambient temperature is low.
When the heater is operated, vehicle
indicator temperature is not still hot
enough.
Air conditioner is operating and
passenger compartment has not
sufficiently cooled.
Demister switch is pressed. Refer to
“Demisting of the windscreen and door
windows: for quick demisting”.
When the air conditioner is operated
in AUTO mode where the temperature
control is set to the max. hot or the
max. cool (for vehicles with automatic
climate air conditioning).
When the diesel particulate filter
(DPF) automatically burns away trapped
particulate matter (PM).
Electric power consumption is high,
such as when the rear window demister
or other electrical components areoperating or the blower speed is set to
a high setting.
Battery voltage or battery
performance is low.
Check engine warning lamp is
illuminated or the
indicator lamp is
blinking.
On 4WD vehicles, the drive
mode-selector in “4H” or “4L” (Easy
select 4WD), “4HLc” or “4LLc” (Super
select 4WD II).
NOTE In the following cases, the
engine will not stop automatically even
if “Start&Stop” indicator lamp turn on.
Push the accelerator pedal
Brake booster vacuum pressure is
low
Operate the steering wheel
Parking on steep hill
NOTE Do not rest your foot on the
clutch pedal while driving because this
will cause detection of clutch pedal
switch malfunction and blinking of the
Start&Stop OFF indicator, and the
Start&Stop system will not operate.
NOTE If the Start&Stop system
operates while the air conditioner is
operating, both the engine and the air
conditioning compressor will stop.
Therefore, only the blower will operate,
the windows may start to fog up. If this
occurs, press the demister switch to
restart the engine. Refer to “Demister
switch”.NOTE If the windows become fogged
up each time the engine is stopped, we
recommend you to deactivate the
Start&Stop system by pressing the
“Start&Stop OFF” switch. Refer to “To
deactivate”.
NOTE If the air conditioner is operating,
set the temperature control higher to
lengthen the time that the engine is
stopped automatically.
Automatically restarting the engine
Depress the clutch pedal while the
gearshift lever is in the “N” (Neutral)
position. The indicator lamp turns off
and the engine restarts automatically.
NOTE Do not move the gearshift lever
to a position other than the “N” (Neutral)
position or do not release the clutch
pedal while the engine is restarting
automatically. The starter motor will
stop and the engine will not restart
automatically.
NOTE If the engine does not restart
automatically or if the engine stalls, the
charge warning lamp and check engine
warning lamp will illuminate. If this
occurs, the engine will not restart even
if the clutch pedal is depressed again.
While depressing the brake pedal, fully
depress the clutch pedal and turn the
ignition switch to the “START” position
or press the engine switch to start the
engine. For details, refer to “Starting
and stopping the engine”.

Passing acceleration
To gain extra acceleration in “D” (DRIVE)
position, push the accelerator to the
floor. The A/T will automatically
downshift.
In sports mode, downshifts do not take
place when the accelerator is
depressed all the way to the floor.
Waiting
For short waiting periods, such as at
traffic signals the vehicle can be left in
gear and held stationary with the
service brake. For longer waiting
periods with the engine running, place
the selector lever in the “N” (NEUTRAL)
position and apply the parking brake,
while holding the vehicle stationary with
the service brake.
132)
Parking
To park the vehicle, first bring it to a
complete stop, fully engage the parking
brake, and then move the selector lever
to the “P” (PARK) position.
If you are going to leave the vehicle
unattended, always switch off the
engine and carry the key.
On a slope, be sure to apply the
parking brake before moving the
selector lever to the “P” (PARK)
position. If you move the selector lever
to the “P” (PARK) position before
applying the parking brake, it may be
difficult to disengage the selector lever
from the “P” (PARK) position when next
you drive the vehicle, requiring
application of a strong force to the
selector lever to move from the “P”
(PARK) position.
When the A/T makes no speed
change
If the transmission does not change
speeds while driving, or your vehicle
does not pick up enough speed when
starting on an uphill slope, it may be
that there is something unusual
happening in the transmission, causing
a safety device to activate. Immediately
have your vehicle checked by a Fiat
Dealership as soon as possible.
1. If your vehicle has difficulty moving
uphill, shift the selector lever into 2nd
gear of the sports mode. This method
might not work depending on the
transmission malfunction.2. Once the vehicle is moving on a level
road, move the selector lever back to
“D” (DRIVE).
When the selector lever position display
in the instrument panel blinks, it means
that there is an abnormal condition in
the transmission. Refer to “When the
selector lever position display blinks”.
IMPORTANT
115)Always depress the brake pedal when
shifting the selector lever into a gear from
the “P” (PARK) or “N” (NEUTRAL) position.
Never put your foot on the accelerator
pedal while shifting the selector lever from
the “P” (PARK) or “N” (NEUTRAL) position.
116)Never shift into the “P” (PARK) or “R”
(REVERSE) position while the vehicle is in
motion to avoid a transmission damage.
117)Never move the selector lever to the
“N” (NEUTRAL) position while driving. A
serious accident could occur since you
could accidentally move the lever into the
“P” (PARK) or “R” (REVERSE) position or
you will lose engine braking.
118)On a gradient, the engine should be
started in the “P” (PARK) position, not in the
“N” (NEUTRAL) position.
119)To prevent rolling, always keep your
foot on the brake pedal when the vehicle is
in “N” (NEUTRAL) position, or when shifting
into or out of “N” (NEUTRAL) position.
120)To prevent transmission damage,
never shift into the “D” (DRIVE) position
from the “R” (REVERSE) position while the
vehicle is in motion.

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
“2WD/4WD operation indicator lamp
and low-range indicator lamp”.

NOTE If the low range lamp blinks
when you attempt to make a “4HLc” —
“4LLc” selection, a “4HLc” — “4LLc”
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.
NOTE The ESC function is suspended
while “4LLc” is selected
indicator
lamp is illuminated while these functions
are suspended. It does not indicate a
problem. When “2H” or “4H” or “4HLc”
is selected, this lamp goes out and
function again. Refer to “ESC indicator
lamp, ESC OFF indicator lamp”.
140)
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).
4. To deactivate the rear differential
lock, press the rear differential lock
switch (B).

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

143)Use the rear differential lock only as an
emergency measure when the vehicle is
stuck and cannot be freed with the transfer
shift lever or the drive mode-selector in “4L”
or “4H” position (Easy Select 4WD) or in
“4LLc” or “4HLc” position (Super Select
4WD II). Deactivate the rear differential lock
immediately after using it.4 WHEEL DRIVE
OPERATION
By selecting 4-wheel drive, both axles
of the vehicle are rigidly connected with
each other. This improves the traction
characteristics. When turning sharp
corners or moving forward and
backward repeatedly, however, the
drive line is stressed, which is felt as a
braking effect. A 4-wheel drive vehicle
can accelerate more quickly and
smoothly.
However, note that the braking distance
is not shorter than that of a rear-wheel
drive vehicle.
When using 4-wheel drive on rough
roads (snow, mud, sand, etc.), it is
important to operate the vehicle
correctly.
NOTE The driving posture should be
more upright and closer to the wheel
than usual; adjust the seat to a good
position for easy steering and pedal
operation. Be sure to wear the seat
belt.
NOTE After driving on rough roads,
check each part of the vehicle and
wash it thoroughly with water. Refer to
“Vehicle care” and “Inspection and
maintenance following rough road
operation”.Driving on dry paved road and
highway
Select “2H” position (Easy Select 4WD),
“2H” or “4H” position (Super Select
4WD II) to drive on the dry paved road.
Especially on dry highway, never select
the “4H” or “4L” position (Easy Select
4WD), “4HLc” or “4LLc” position (Super
Select 4WD II).
144)
Driving on snowy or icy roads
Set the drive mode-selector to “4H”
position (Easy Select 4WD), “4H” or
“4HLc” position in accordance with the
road conditions (Super Select 4WD II)
and then gradually depress the
accelerator pedal for a smooth start.
Keep the pressure on the accelerator
pedal as constant as possible, and
drive at low speed.
NOTE The use of snow tyres and/or
tyre chains is recommended.
NOTE Maintain a safe distance
between vehicles, avoid sudden
braking, and use engine braking
(downshifting).
145)
Driving on sandy or muddy roads
Set the drive mode-selector to “4H” or
“4L” position (Easy Select 4WD),
“4HLc” or “4LLc” position (Super Select
4WD II) and then gradually depress the
accelerator pedal for a smooth start.
Keep the pressure on the accelerator
181

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

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.
