SAFETY
78
General Information
This vehicle has systems that operate on
radio frequency that comply with Part 15 of
the Federal Communications Commission
(FCC) rules and with Industry Canada Stan
-
dards RSS- GEN/210/220/310.
Operation is subject to the following two
conditions:
1. The device may not cause harmful inter
-
ference.
2. The device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modifications to any of these
systems by other than an authorized service
facility could void authorization to use this
equipment.
Tire Pressure Monitoring System (TPMS)
This vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that sends the
inflation pressure information of each tire to
the control unit, and will signal the driver in
the event of insufficient tire pressure.
Tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will
also decrease. Tire pressure should always
be set based on cold inflation tire pressure.
This is defined as the tire pressure after the
vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire infla
-
tion pressure must not exceed the maximum
inflation pressure molded into the tire side
-
wall. Refer to “Tires” in “Servicing And
Maintenance” for information on how to
properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is
driven. This is normal, and there should be
no adjustment for this increased pressure.
The TPMS will signal the driver if pressure
falls below the warning limit for any reason,
including the effects of low temperature and
normal loss of pressure from the tire.
The TPMS will stop indicating insufficient
tire pressure when pressure is equal to or
greater than the prescribed cold inflation
level. Therefore, if insufficient tire pressure
is indicated by the (
) warning light
displaying in the instrument cluster,
increase the inflation pressure up to the
prescribed cold inflation value.
The system will automatically update, and
the “Tire Pressure Monitoring Telltale Light”
will turn off once the system receives the
updated tire pressures. 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.
Operating Example
For example, your vehicle may have a recom
-
mended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa).
If the ambient temperature is 68°F (20°C),
and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F
The system may activate, assessing the
trajectory of the vehicle, for the presence
of reflecting metal objects different from
other vehicles, such as safety barriers,
road signs, barriers before parking lots,
tollgates, level crossings, gates, railways,
objects near road constructions sites or
higher than the vehicle (e.g. a fly-over).
In the same way, the system may inter
-
vene inside multi-story parking lots or
tunnels, or due to a glare on the road
surface. These possible activations are a
consequence of the real driving scenario
coverage by the system and must not be
regarded as faults.
The system has been designed for road
use only. If the vehicle is driven on a
track, the system must be deactivated to
avoid unnecessary warnings. Automatic
deactivation is signaled by the dedicated
warning light/symbol switching on in the
instrument panel (refer to the instruc
-
tions in the "Warning Lights And
Messages On The Instrument Panel" in
"Getting To Know Your Instrument
Panel" for further information).
