above 41 °F
(+5 °().
-Always remember, even if the "snow­
f la ke" symbo l (ice warning) does not ap­
pear in the disp lay, black ice could be on
the road.
-Always reduce your speed and d rive with
special care in cold weather cond itions
when the chance of encountering icy road surfaces increases.
(j) Tips
- At temperatures below 14 °F (+ 5 °C) a

pear in the instrument cluster display
c:;, fig. 84 . The display may vary, depending on
the type of display in your vehicle . The indic a­
tor light . in the instrument cluster also illu­
minates.
The speed is kept constant
via an engine out­
put adjustment or active brake intervention .
8_ 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 contro l
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
plan ing) - risk of accident.
- Turn off the cruise control temporarily when enter ing turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the drive r's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched 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
m:lmi (US models)/ . (Canadian mod­
els) is on.
(D Tips
The brake lights illuminate as soon as th e
brakes decelerate automatically.

lever pressed down , you will alter your speed
in 5 mph (10 km/h) increments .
You can also press the accelerator pedal down
to increase your speed, e .g. if you want to
pass someone . The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however, you exceed your saved speed by
6 mph (10 km/h) for longer than 5 minutes,
the cruise control will turn off temporari ly.
