NOTE:
•
Changing the FCW status to “Only Warning” pre-
vents the system from providing limited active brak-
ing, or additional brake support if the driver is not
braking adequately in the event of a potential frontal
collision, but maintains the audible and visual
warnings.
•
Changing the FCW status to “Off” prevents the sys-
tem from providing autonomous braking, or addi-
tional brake support if the driver is not braking
adequately in the event of a potential frontal
collision.
•
The system will retain the last setting selected by
the driver after ignition shut down.
•
FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects not in
the path of the vehicle, stationary objects that are
far away, oncoming traffic, or leading vehicles with
the same or higher rate of speed.
•
FCW will be disabled like ACC, with the unavailable
screens.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW Limited
Functionality” or “ACC/FCW Limited Functionality Clean
Front Windshield” momentarily, there may be a condi-
tion that limits FCW functionality. Although the vehicle
is still drivable under normal conditions, the active
braking may not be fully available. Once the condition
that limited the system performance is no longer pres-
ent, the system will return to its full performance state.
If the problem persists, see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster dis-
plays:
•
ACC/FCW Unavailable Service Required
•
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal condi-
tions, have the system checked by an authorized
dealer.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
NOTE:
For vehicles equipped with run flat tires, when the
TPMS indicates a tire pressure of 14 psi (96 kPa) or
lower, always check tire pressure and replace the tire at
the first opportunity. At inflation pressure of or below 14
psi (96 kPa) the tire is in the Run Flat mode of opera-
tion. In this condition, it is recommended that a vehicle
keep a maximum speed of 50 mph (80 km/h) for a
maximum distance of 50 miles (80 km). The manufac-
turer does not recommend using the run flat feature
while driving a vehicle loaded at full capacity or towing
a trailer.
The TPMS will warn the driver of a low tire pressure
based on the vehicle recommended cold tire pressure.
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 pres-
sure 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.
See
page 284 on how to properly inflate the vehi-
cle’s tires.
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 recom-
mended 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). This tire pressure is sufficiently low enough
to turn on the TPMS Warning Light. Driving the vehicle
