Collision Warning is on, the system will perform
a self-test each time the engine is started by
briefly illuminating the warning light. See page

When the engine is switched on, the Collision
Warning setting that was being used when it
was switched off will be the default setting.
NOTE

Warning distance .
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal .
WARNING
• The setting Short should only be used
in situations where traffic is light and
moving at low speeds.
• Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
• For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 149.
NOTE
• When Adaptive Cruise Control is used,
the warning light and signal will be used
by that function, even if the warnings
provided by Collision Warning have
been deactivated by the driver.
• In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting
Long has been selected.
Checking settings
The current Collision Warning settings can be
checked by pressing MY CAR on the center
console control panel and going to
Settings
Car settings Driver support systems

Limitations
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult to see.
For this reason, always activate the audible
warning signal.
Slippery driving conditions increase braking
distance, which can reduce the system's
