Tire Pressure Monitoring System (Tpms) - Maserati GranTurismo Owner's Manual

Understanding the Vehicle
Tire Pressure Monitoring
System (TPMS)
The Tire Pressure Monitoring System
(TPMS) will warn the driver of a low
2
tire pressure according to the vehicle
recommended cold pressure indicated
on the table "Tire Inflation Pressure" in
section "Technical Specifications" and
on the label applied on the rear driver
door's ledge (only for vehicles on the
Australian market).
Tire pressure should always be set
based on cold inflation tire pressure.
The cold tire inflation pressure must not
exceed the maximum inflation pressure
moulded into the tire sidewall. Check
"Tires Information" in this section for
information on how to properly inflate
the tires.
The tire pressure will also increase as
the vehicle is driven - this is normal and
there is no adjustment required when
this occurs.
The TPMS will warn the driver of a low
tire pressure if the tire pressure falls
below the low-pressure warning limit for
any reason, including low temperature
effects and natural pressure loss of the
tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition persists and will not turn
52
off until the tire pressure is equal or
above the recommended cold inflation
pressure. Once the low tire pressure
warning light illuminates, you
must increase the tire pressure to the
recommended cold inflation pressure in
order for the TPMS light
The system will automatically update
and the TPMS light will turn off once
the system acquires the correct tire
pressure.
The vehicle may need to be driven for up
to 20 minutes above 24 km/h (15 mph)
in order for the TPMS to acquire and
process the updated setting.
For example: If your vehicle (stationary
for more than three hours) may have a
recommended cold inflation pressure
of 2.1 bar. If the ambient temperature
is 20°C (68°F) and the measured tire
pressure is 1.8 bar, a temperature drop
to 7°C (12°F) will decrease the tire
pressure to approximately 1.6 bar. This
tire pressure is sufficiently low to turn
ON the TPMS Light
vehicle may cause the tire pressure
to rise to approximately 1.8 bar, but
the TPMS light
situation, the TPMS light
to turn off.
OFF only after the tires are inflated to the
vehicle's recommended cold inflation
pressure value.
WARNING!
The TPMS warns the driver that the
tire pressure has decreased. This
warning does not exempt the driver
from periodically checking the tires and
from complying with the prescribed tire
pressure levels.
CAUTION!
•
The TPMS has been optimised for the
original equipment tires and wheels.
TPMS pressures and warning have
been established for the tire size
equipped on your vehicle. Undesirable
system operation or sensor damage
may occur when using replacement
equipment that is not of the same size,
type, and/or style. Aftermarket wheels
can cause sensor damage. Do not use
aftermarket tire sealants or balance
beads if your vehicle is equipped with a
