style. Aftermarket wheels can cause
sensor damage. Do not use
aftermarket tire sealants or balance
beads, as damage to the sensors may
result.
• The system can temporarily
experience radio-electric interference
emitted by devices using similar
frequencies.
• After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve
stem and damage the TPMS internal
sensor.
NOTE:
•Driving on a significantly
underinflated tire causes the tire to
overheat and may lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an
accurate tire pressure gage, even if
under-inflation has not reached thelevel to trigger illumination of the
TPMS light
.
•Seasonal temperature changes will
affect tire pressure, and the TPMS
will monitor the actual tire pressure
in the tire.
Viewing Messages on the
Display
By pressing repeatedly the “MODE”
button of the control panel on left
side of the steering column, the user
can access the information page that
shows the pressure values of each tire
(“Tire Pressure” screen page: see
paragraph "TFT Display: Screen Pages"
in chapter "Instrument Cluster" of
section "Dashboard Instruments and
Controls").
If system faults or low pressure is
detected on a not indentified tire,"Check Tire Pressure" or "TPMS
Malfunction" pop-up message will be
displayed for 10 seconds. The
amber warning light will
permanently illuminate on the right
side of the instrument cluster display.
With a malfunction detected, the "Tire
Pressure" screen page will not be
available while will be available the
calibration screen page.
The “Tire Pressure” screen page
becomes available again, until the
malfunction is corrected.
Low Tire Pressure Conditions
The signal transmitted by the ECU
activates messages and symbols on the
TFT display with two priority levels
corresponding to the following
thresholds:
• Soft Warning: if the pressure is 10%
lower than the rated pressure;
• Hard Warning: if the pressure is 17%
lower than the rated pressure.
The system refers to the rated pressure
acquired after calibration.
The two alarm thresholds for
monitoring the tire pressure
respectively activate the following
alerts:
• “Check tire pressure” illuminates on
the display when the pressure of one

with the key removed to the ignition
switch.
• Remember that passing other
vehicles when driving uphill is slower
and thus requires more free distance
on the road. If you are being
overtaken on a hill, slow down and
allow the other vehicle to pass.
Driving on Snow or Ice
Please consider some general advice
for driving in these conditions, listed
below.
• Maintain a very moderate speed.
• Fit snow chains or specific tires if the
road is covered with snow: see the
paragraphs “Tires – General
Information” in this section.
• We recommend you to activate the
“ICE” drive mode (see chapters
“Drive Mode” in this section).
• During the winter season, even
apparently dry roads can have icy
sections. Be careful when crossing
bridges, viaducts and roads that have
little exposure to the sun and are
bordered by trees and rocks. They
may be icy.
• Keep an ample safe distance from
the vehicles in front of you.
• Avoid sharp braking, sharp changes
in direction and rapid acceleration.Rapid acceleration on snow covered
or icy surfaces may cause the driving
wheels to pull erratically to the right
or left. This phenomenon occurs
when there is a difference in the
surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces
is dangerous. Unequal traction can
cause sudden pulling of the rear
driving wheels. You could lose control
of the vehicle and possibly have a
collision. Accelerate slowly and
carefully whenever there is likely to be
poor traction (ice, snow, wet mud,
loose sand, etc.).
Driving through Flooded
Sections
Driving through more than a
centimeters deep shallow standing
water section will require extra
caution to ensure passenger safety and
prevent damage to your vehicle.
WARNING!
Do not drive on or across a road or
path where water is flowing and/or
rising (as in storm run-off). Flowing
water can wear away the road or path
surface and cause your vehicle to sink
into deeper water. Furthermore,
flowing and/or rising water can carry
your vehicle away swiftly. Failure to
follow this warning may result in
injuries that are serious or fatal to
you, your passengers, and others
around you.
Although your vehicle is capable of
driving through shallow standing
water, consider the following Caution
and Warning before doing so.
CAUTION!
• Always check the depth of the
standing water before driving
through it. Never drive through
standing water that is deeper than
the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road
or the path that is under water and if
there are any obstacles in the way

Using the Compact Spare
Wheel (for versions/markets
where provided)
Upon request, the vehicle may come
equipped with a compact spare wheel
(emergency wheel), jack and tools for
replacing a wheel.
The compact spare wheel is stored in
the trunk and housed in a bag: it is
supplied deflated in order to limit the
amount of space occupied. An electric
compressor is also provided for
inflating.
The bag covering the compact spare
wheel has a side pocket containing
the protective bag for the standard
wheel that has been removed along
with a pair of gloves.
In the event of a tire puncture,
proceed as follows.
• Stop the vehicle in a place that does
not constitute a danger to traffic
and where the wheel can be
changed safely. The vehicle must be
level and on firm ground.
• Select the P (Park) mode and then
engage manually the electric
parking brake and turn the key in
the ignition switch toSTOP (OFF)
position.

• Remove from the compressor case
the inflation hose and the cable with
a plug for the power outlet.
• Unscrew the valve cap of the
compact spare wheel and screw the
fitting of the inflation hose onto the
valve.
• Insert the plug in one of the
available power outlets fitted in the
trunk or passenger compartment.
• Turn the key in the ignition switch in
MAR (ON)position.
• Turn the compressor on by pressing
the switch.
• Stop the compressor pressing switch
again, when the pressure indicated
by the gage reaches the
recommended level (see “Tire
Inflation Pressure” in section
“Features and Specifications”) and
screw the cap on the compact spare
wheel valve.
CAUTION!
• In order to obtain a more accurate
reading, the compressor should be
switched off when checking the tire
pressure of the compact spare wheel
on the pressure gage.
• Do not run the compressor for more
than 20 minutes: there is a risk it
could overheat. Also, prolonged
power absorption may discharge the
battery, subsequently preventing the
engine from starting.
• The compressor has been designed
exclusively to inflate compact spare
wheels; do not use it to inflate air
mattresses, dinghies etc.
• Fit the adapter on the wrench.
Extend the wrench as shown, then
loosen by approximately one turn,the five bolts on the wheel to be
changed.
• Open the jack partially, releasing and
turning the control lever clockwise.
• Place the jack near the wheel to be
