192Driving and operatingFollowing distanceindication
The following distance indication
displays the distance to a preceding
moving vehicle. The system uses,
depending on the vehicle equipment,
either the radar behind the radiator
grille or the front camera in the
windscreen to detect the distance of
a vehicle directly ahead in your lane.
It is active at speeds above 25 mph.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 116.
Press MENU on the turn signal lever
to select Vehicle Information Menu
X and turn the adjuster wheel to
choose following distance indication
page.
The minimum indicated distance is 0.5 s.
If there is no vehicle ahead or the
vehicle ahead is out of range, two
dashes will be displayed: -.- s.
Active Emergency Braking
Active emergency braking can help to reduce the damage from crashes with vehicles and obstacles directly
ahead, when a collision can no longer be avoided either by manual braking
or by steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert 3 188.
The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle speed) to calculate the probability of
a frontal collision.
Active emergency braking operates automatically above walking speed,
provided that Auto collision
preparation setting is not deactivated
in the vehicle personalisation menu
3 129.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist9Warning
This system is not intended to
replace the driver responsibility of driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver shall continue to apply the brake
pedal as the driving situation
dictates.

Driving and operating205An exclamation mark in a frame
indicates that there is an additional
sign detected which cannot be
recognised by the system.
The system is active up to a speed of
124 mph depending on the lighting
conditions. At night the system is
active up to a speed of 99 mph.
As soon as vehicle speed becomes
slower than 34 mph the display will be
reset and the content of the traffic sign page will be cleared, e.g. when
entering a city zone. The next
recognized speed indication will be
displayed.
Display indicationTraffic signs are displayed on the
page Traffic sign detection in the
Driver Information Centre, chosen via the adjuster wheel on the turn signal
lever 3 116.
When another function in the Driver Information Centre menu was
selected and then Traffic sign
detection page is chosen again, the
last recognised traffic sign will be
displayed.
After the traffic sign page is cleared
by the system, the following symbol is
indicated:The content of the traffic sign page is also cleared during driving by
pressing and holding SET/CLR on the
turn signal lever.
Pop-up function
Speed limits and no passing signs are
displayed as pop-ups on each page
of the Driver Information Centre.
Page 208 of 305

206Driving and operating
The pop-up function can be
deactivated on the traffic sign page by
pressing SET/CLR on the turn signal
lever.
Once the Settings page is displayed,
select Off to deactivate pop-up
function. Reactivated by selecting
On . When switching on the ignition,
pop-up function is deactivated.
Pop-up indication is displayed for
approx. 8 seconds in the Driver
Information Centre.
Fault
The traffic sign assistant system may
not operate correctly when:
● The area of the windscreen, where the front camera is
located, is not clean.
● Traffic signs are completely or partially covered or difficult to
discern.
● There are adverse environmental
conditions, e.g. heavy rain, snow,direct sunlight or shadows. In this
case No Traffic Sign Detection
due to Weather is indicated in the
Driver Information Centre.● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on traffic
signs (Wiener Übereinkommen
über Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.

Vehicle care247Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 277.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 288.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition. After adjusting tyre
pressure, switch on ignition and
select the appropriate setting on the
page Tyre load in the Driver
Information Centre, 3 116.
Tyre pressure monitoring system
The tyre pressure monitoring system
(TPMS) checks the pressure of all
four tyres once a minute when vehicle speed exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Centre.
The menu can be selected by the buttons on the turn signal lever.
Press MENU to select the Vehicle
Information Menu X .
