gine is running. When the engine off, you
must use more force to steer or brake
the vehicle. Because the usual steering
and brak ing capability is not avai lab le,
the risk of accidents or injur ies increases.
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies part ic­
ularly when children remain in the veh i­
cle. Otherwise the ch ild ren could start
the engine or operate electrical equip­
men t such as power w indows.
(D Note
- Avo id h igh engine speed, full throttle,

pedal has failed or the brake pedal is ob­
structed . Du ring emergency braking, your
vehicle will brake similar to heavy braking.
ESC and the assoc iated components (ABS,
ASR, EDL) cannot overcome the laws of
physics. In corners and w hen road or
weather conditions are bad, a full brake
application can cause the vehicle to skid or
the rear end to b reak away, which increas­
es the risk of an acc ident.
Hill hold
Applies to vehicles: with H ill Hold

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed .
The speed warning system war ns you if you
are exceeding the maximum speed that you
have set . You will hear a warning tone when
yo ur speed exceeds the stored value by ap­
proximate ly 3 mph (3 km/h). The . (U SA
models)/ . (Canada models) ind icator light
and the message
Speed limit e xceeded! ap­
pear in the instrument cluster display at the
same time. The./. indicator light turns ..,.

off when the speed decreases below the stor­
ed maximum speed.
Setting a thresho ld is recommended if yo u
wo uld like to be reminded when you reach a
certain maximum speed . Situations where you
may want to do so include d riving in a country
with a general speed limit or if there is a
specified max imum speed for winter tires.
@ Tips
Regard less of the speed warning system,
you shou ld always mon itor your speed us­
ing the speedometer and make sure you
are following the legal speed limit.
Setting the threshold
You con set, change and delete the threshold
in the MMI.
• Se lect : the
IMENU ! button> Car> System s*
control button > Driv er assist an ce > Speed
w arning .
You can set any thresho ld between 20 mph
(30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Appl ies to vehicles : with cruise con trol system
The c ruise control system makes i t possible to
d rive at a constant speed starting at lS mph
(20 km/h).
The speed is kept constant by modify ing en­
g ine power or through an a ct ive brake in ter ­
vention.
A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise contro l
should not be used in the c ity, in stop-
Dri vin g 85
and-go traffic, on winding roads and
when road cond itions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway
e xits or in construction zones.
- Please note that unconsc iously "resting"
your foot on the accelerator pedal p re­
vents t he cr uise control from b raking.
This is due to the control system be ing
over ridden by the dr iver's acceleration .
- If the re is a brake system malfunct ion
such as overheating when the spee d
warn ing system is switched on, the bra k­
ing f unction in the system w il l be deac ti­
vated . The remaining speed warning sys ­
tem fu nctions will remain active, as long
as the
Ill ( U SA mode ls) I l'I (Canada
models) indicator light is on.
(D Tips
- T he cr uise control system is ideal fo r
st retches wit h speed limits. The driver is
responsib le for adhering to the correct
speed.
- The cr uise control remains act ive when
shift ing gears.
- The b ra ke lights turn on when the b rakes
are act ivated.
