2018 Alfa Romeo 4C Spider tires

•Driving on a significantly under-inflated tire causes
the tire to overheat and can 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 mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the Tire Pressure Monitoring
Telltale Light.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
Base System
This is the TPMS warning indicator located in
the instrument cluster. The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure
levels. Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an acoustic signal will be
activated, and the “Check left or right front/rear tire”
text message will display when one or more of the four
active road tire pressures are low. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each
tire to the vehicle’s recommended cold placard pressure
value. The system will automatically update and the
98 SAFETY

Tire Pressure Monitoring Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a
system fault is detected, the “TIRE PRESSURE MONI-
TORING UNAVAILABLE” text message will display. If
the ignition key is cycled, this sequence will repeat
providing the system fault still exists. The Tire Pressure
Monitoring Telltale Light will turn off when the fault
condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Your vehicle may be equipped with a compact
spare wheel and tire assembly.
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure
warning limit, upon the next ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will still turn ON due to the low tire.
3.
However, after driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid.
4. This occurs for each subsequent ignition key cycle, a chime will sound and the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid.

SAFETY 99

5. Once you repair or replace the original road tire andreinstall it on the vehicle in place of the compact
spare tire, the TPMS will update automatically and
the Tire Pressure Monitoring Telltale Light will turn
OFF, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

Here are some simple steps you can take to minimize
the risk of harm from a deploying air bag:
1. Children 12 years old and under should always ride buckled up in a vehicle with a rear seat.
100 SAFETY

WARNING!(Continued)
•NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator, brake, or
clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the
floor and check the floor mat fasteners are secure
to the vehicle carpet. Fully depress each pedal to
check for interference with the accelerator, brake,
or clutch pedals then re-install the floor mats.
• It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using the
floor mat fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights
and exterior lights while you work the controls. Check
turn signal and high beam indicator lights on the
instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking
for fuel, coolant, oil, or other fluid leaks. Also, if
gasoline fumes are detected or if fuel, or brake fluid
leaks are suspected. The cause should be located and
corrected immediately.

SAFETY 135

Fault Indication
Parking sensor failures, if any, will be indicated when
REVERSE gear is engaged by the switching on of the
warning light in the instrument cluster display.
General Warnings
When parking, take the utmost care over obstacles that
may be above or under the sensor.
Under certain circumstances, objects close to the vehicle
are not detected by the system and could therefore
cause damage to the vehicle or be damaged themselves.
Some conditions may influence the performance of the
parking sensors:
• The presence of ice, snow, mud or multiple layers of
paint on the sensor surface may cause reduced
sensitivity of the sensor itself and therefore reduce
the system performance.
• Mechanical interference (e.g washing the vehicle,
rain, strong wind, hail) may cause the sensor to
detect a non-existent obstacle (“echo interference”).
• The presence of ultrasonic systems (e.g. pneumatic
brake systems of trucks or pneumatic drills) near the
vehicle could alter the signals sent by the sensor. •
The variation in sensor position, caused by variation
in ride (due to suspension component wear), chang-
ing tires, overloaded vehicle, or tuning that lowers
the vehicle, for example, may affect parking sensor
system performance.
NOTE: The sensor must be free from mud, dirt snow or
ice in order for the system to operate correctly. Be
careful not to scratch or damage the sensors while
cleaning them. Avoid using dry, rough or hard cloths.
The sensors must be washed using clean water, with the
addition of car shampoo if necessary. When using
special washing equipment such as high pressure jets or
steam cleaning, clean the sensors very quickly keeping
the jet more than 4 inches (10 cm) away. Also, do not
apply stickers to the sensors.
WARNING!
Drivers must be careful when backing up even
when using the Parking Sensor system. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing up. You
are responsible for the safety of your surroundings

158 STARTING AND OPERATING

Traction
When driving on wet or slushy roads, it is possible for
a wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
•Slow down during rainstorms or when the roads are
slushy.
• Slow down if the road has standing water or
puddles.
• Replace tires when tread wear indicators first become
visible.
• Keep tires properly inflated.
• Maintain sufficient distance between your vehicle
and the vehicle in front of you to avoid a collision in
a sudden stop.
Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not eliminate,
the amount of wheel slip across a given axle for
improved handling.
Driving Through Water
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s 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.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cau-
tions and Warnings before doing so.

Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Frequent fluid level checks are not required, but have
your authorized dealer check the fluid level as specified
in the Maintenance Schedule to ensure proper transmis-
sion function and longevity. The transmission has no
dipstick, but your authorized dealer can check your
transmission fluid level using special service tools. If
you notice fluid leakage or transmission malfunction,
visit your authorized dealer immediately to have the
transmission fluid level checked. Operating the vehicle
with an improper fluid level can cause severe transmis-
sion damage.
Fluid Changes
Under normal operating conditions, the fluid installed
at the factory will provide satisfactory lubrication for
the life of the vehicle. However, change the fluid if it
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
RAISING THE VEHICLE
In the case where it is necessary to raise the vehicle, go
to an authorized dealer or service station.
