SAFETY 253
Changing the PEB status to “Off” deactivates
the system, so no warning or active braking will
be available in case of a possible frontal
collision with the pedestrian/cyclist.
NOTE:
The PEB system will retain the last setting
selected by the driver after ignition shut down.
The system will not reset to the default setting
when the vehicle is restarted.
Intersection Collision Assist (ICA) —
If Equipped
ICA uses three front radar sensors located in
the front fascia/bumper, to detect oncoming
vehicles from the front or side when driving
through an intersection. When the system
determines that a collision is probable, the
driver will attempt to mitigate a possible
collision by decelerating the vehicle. The system
will also provide audible warnings and visual
warnings (shown in the instrument cluster). If
the driver determines acceleration is needed to
avoid a collision, when the accelerator is
pressed ICA will cancel.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire
pressure based on the vehicle recommended
cold tire pressure Ú page 395.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will 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
tire pressure will also increase as the vehicle is
driven — this is normal and there should be no
adjustment for this increased pressure.
For information on how to properly inflate the
vehicle’s tires, see Ú page 364.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the low
pressure warning threshold for any reason,
including low temperature effects, or natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at
or above recommended cold tire pressure.
Once the low tire pressure warning has been
illuminated, the tire pressure must be increased
to the recommended cold tire pressure in order
for the TPMS Warning Light to be turned off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
The system will automatically update and the
TPMS Warning 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.
For example, your vehicle has a recommended
cold (parked for more than three hours) tire
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 (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa).
