capacity to avoid a collision. In these condi-
tions, the ABS and DSTC systems provide the
best possible braking effect while helping to
maintain stability.
NOTE
The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger compartment temperature due to strong
sunlight, etc. If this occurs, the audible
warning signal will be used, even if it has
been deactivated in the menu system.
WARNING
• In certain situations, the system cannot
provide warnings or warnings may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian or a vehicle ahead.
• Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
• The sensor system has a limited range
for pedestrians and provides warnings
and braking effect most effectively at
speeds up to 30 mph (50 km/h). For sta-
tionary or slow-moving vehicles, the
system functions best if your vehicle’s
speed is below approximately 45 mph
(70 km/h).
• Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions or in poor visibility.
The Collision Warning system uses the same
radar sensors as Adaptive Cruise Control. For
more information on the radar sensor and its
limitations, see page 144.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 160). This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
WARNING
• The system is not activated at speeds
under approx. 2 mph (4 km/h). There-
fore, it will not brake your vehicle if you
approach a vehicle ahead at very low
speed, such as when parking.
• The driver's actions always have high-
est priority and override the Collision
Warning system. This means that the
system will not intervene in situations
where the driver is actively steering,
braking or pressing the accelerator
pedal, even if a collision is imminent.
• When Auto-brake has prevented a col-
lision with a stationary object, your vehi-
cle will remain at a standstill for approx.
1.5 seconds. If your vehicle has been
braked for a moving vehicle ahead, your
vehicle's speed will be reduced to the
same speed as that vehicle's.
