●The limits of tire gripping performance have been exceeded.
●If the vehicle hydroplanes while driving at high speed while the road is wet or
slick.
■Stopping distance when the ABS is activated will exceed that of normal condi -
tions
The ABS is not designed to shorten the v
ehicle’s stopping distance. Always main -
tain a safe distance between you and the vehicle in front of you, particularly in the
fo
llowing situations.
• When driving on dirt, gravel or snow-covered roads
• When driving with tire chains
• When driving over bumps in the road
• When driving over roads with potholes or uneven roads

CAUTION
■Pre-collision system limitations
●The Pre-Collision System is designed to help reduce the crash speed and dam-
age in certain frontal collisions only. It is not a collision avoidance system and is
no
t a substitute for safe and attentive driving. System effectiveness depends on
many factors, such as speed, dr iver input and road conditions.
●The sensor is able to detect objects in front of the vehicle within 10 degrees on
either side. If the object is out of range, or there is little to no millimeter wave
reflection, the sensor will not detect the object.
●Even if the system is operative in a collisio n, unless the seat belts are worn and the
brake pedal is depressed, the pre-collision seat belts and brake assist system will
operate.
■Failure Warning
If an error is detected, the master warn i
ng light comes on, a warning tone sounds
and the following warning message appears on the multi-information display.
