A WARNING
-Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between your vehicle and other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twisting roads and
when road conditions are poor (such as
ice, fog, grave l, heavy rain and hydro ­
planing) -risk of accident .
- Turn off the cruise control temporari ly
when entering turn lanes, highway exit lanes or in construction zones.
- Please note that inadvertently "rest ing "
yo ur foot on the accelerator peda l causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acce leration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is sw itched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
[~jlQ~i4 (US models) I ii (Canad ian mod­
els) is on.
The brake lights illuminate as soon as the brakes decelerate automat ically .

ahead reduces the t ime and distance
available to br ing your vehicle to a safe

good judgment, and select a safe follow- ing distance for the traffic, road and
weather conditions.

Braking guard uses radar sensors and a video
camera . It a lso functions within the lim its of
the system whe n adapt ive cruise control is
switched off .
What can braking guard do? When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if y our own veh icle is traveling at a
high speed and approaching a veh icle up
ahead that is moving more slowly . Bra king
g ua rd does not react if i t cannot detect th e
si tuation.
The system advises you of va rious situations:
- The distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will not be able to avoid a col lisio n. The indicator
light
I i n the display comes on .
- The approach warning is g iven when a de­
tected vehicle up ahead in yo ur lane is mov ­
i ng much more slowly tha n you are o r if it
b rakes sha rply . When this wa rning is given,
i t may only be possib le to av oid a collision

co llision.
- The system can initiate maximum brak ing
short ly before a co llision

at high speeds occurs only in vehicles with
adapt ive cr uise control and side assist (pre
sense plus).
- If the brak ing g uard senses that yo u are not
