WARNING:The collision warning system’s brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle’s brakes. The brake pedal must be pressed
just like for any typical braking situation.
Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor, located behind a
fascia cover near the driver side of
the lower grille, have been
obstructed. When the radar signals
are obstructed, a vehicle ahead
cannot be detected and the Collision
Warning system will not function.
The following table lists possible causes and actions for this message
being displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain, spray, snow, or fog is
interfering with the radar signalsDo not use the Collision Warning
System in these conditions
because it may not detect, warn,
or respond to potential collisions
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signalsDo not use the Collision Warning
System in these conditions
because it may not detect, warn,
or respond to potential collisions

CHANGING THE TIRES
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensor, refer toChanging tires with TPMSin theTires,
Wheels and Loadingchapter. Replace the spare tire with a road tire as
soon as possible.
WARNING:The use of tire sealants may damage your Tire
Pressure Monitoring System and should not be used.
WARNING:Refer toTire Pressure Monitoring System (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.

WARNING:Failure to follow these guidelines could result in an
increased risk of loss of vehicle control, injury or death.
