the lanes are diverted, e.g. in motorway
roadworks
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip
under braking or acceleration. The vehi-
cle could start to skid.
R if the sensors are dirty or there is poor
visibility, e.g. due to snow, rain or fog.
Distance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. You may
not otherwise recognise dangers in time,
could cause an accident and injure yourself
and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to 180 km/
h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
depending on its speed. This cor-
responds to approximately 20% of your
vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient to avoid a
collision.

the vehicle in front becomes too small. i
If
you do not fully release the accelerator
pedal, the DISTRONIC override message
appears in the multi-function display. The
distance to a slower-moving vehicle in front
will not then be governed. You will be driv-
ing at the speed you determine by the posi-
tion of the accelerator pedal.

is not deactivated if you depress
the accelerator pedal. If you accelerate
briefly to overtake, Distronic adjusts the
vehicle's speed to the last speed stored
after you have finished overtaking.
i Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes. On long
downhill gradients, the automatic trans-
mission shifts down as a further measure. Making adjustments in 1 km/h incre-
ments X

When Distronic is activated, one or two seg-
ments in the set speed range light up.
i For design reasons, the speed displayed
in the speedometer may differ slightly from
the speed set for Distronic. 1
Segments
If Distronic detects a vehicle in front, the seg-
ments between the speed of the vehicle in
front and the stored speed light up. The
l distance warning lamp in the instru-
ment cluster lights up if the distance to the
vehicle in front is too small. G
Risk of accident
If Distronic detects a risk of collision with
the vehicle in front:

142 Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2 or 3 in good time. In this way you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. If you need addi-
tional braking, depress the brake pedal
repeatedly rather than continuously. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. You can set a variable or permanent limit
speed:
R
Variable for speed limits, e.g. in built-up
areas
R Permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
(Y page 144) G
Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic With the cruise control lever you can operate
cruise control, Distronic* and variable
Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R
LIM indicator lamp off: Cruise control or Distronic* is selected
R LIM indicator lamp lit:
variable Speedtronic is selected
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. 1

Variable Speedtronic is deactivated automat-
ically when you depress the accelerator pedal
beyond the pressure point (kickdown). but
only if your current speed does not differ by
more than 20 km/h from the stored speed.
You will hear a warning tone if this is the case.
G
Risk of accident
It is not possible to deactivate variable
Speedtronic by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent Speedtronic i
Permanent Speedtronic is only available
for certain countries.
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres)
and the maximum speed.
Shortly before the stored speed is reached, it
is shown in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). Setting permanent Speedtronic

148 Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It does not relieve you of the
responsibility to pay attention.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger yourself and others. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
Parktronic is an electronic parking aid. It indi-
cates visually and audibly the distance
between your vehicle and an object.
Parktronic is automatically activated when
you switch on the ignition and release the
parking brake.
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.1 Sensors in the front bumper
Range of the sensors
The sensors must be free of dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them.

Risk of injury
Never leave children unsupervised in the
vehicle. They could operate the sliding/tilt-
ing sunroof and injure themselves. Always
take the key with you when leaving the
vehicle, even if you only leave it for a short
time. G
Risk of injury
Make sure that nobody can become trap-
ped when you are opening and closing the
sliding/tilting sunroof. If danger threatens,
release the switch and push it briefly in any
direction to stop the sliding/tilting sunroof. G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that you
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the risk
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid-
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior.
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises.
i It is also possible to open and close the
sliding/tilting sunroof from the outside
using the "Summer opening" ( Y page 100)
and "Convenience closing" ( Y page 100)
features respectively. Controls
