Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention has to be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and
142Driving and operating
When the system detects a vehicle inthe side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber
warning symbol B will light up in the
relevant exterior mirror. If the driver
then activates the turn signal, the
warning symbol B starts flashing
amber as a warning not to change
lanes.
Side blind spot alert is active from
speeds of 6 mph up to 87 mph.
Driving faster than 87 mph deactives
the system, indicated by low lighting warning symbols B in both exterior
mirrors. Reducing the speed again
will extinguish the warning symbols. If a vehicle is then detected in the blindzone, the warning symbols B will
illuminate as normal on the relevant
side.
When the vehicle is started, both
exterior mirror displays will briefly
come on to indicate that the system is
operating.
The system can be activated or
deactivated in the Info-Display,
vehicle personalisation 3 97.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zonesThe detection zones start at the rear
bumper and extend approx.
3 metres rearwards and to the sides. The height of the zone is approx.
between 0.5 metres and 2 metres off
the ground.
Side blind spot alert is designed to ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.Fault
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions

In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.

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 relevant setting on the page Tyre
load in the Driver Information Centre,
3 86.
Tyre pressure monitoring
system The tyre pressure monitoring system
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.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information Centre
with Uplevel-Display.
The menu can be selected with the
buttons on the turn signal lever.
Press the MENU button to select the
Vehicle Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
Vehicle care173
A detected low tyre pressure
condition is indicated by the control
indicator w 3 84.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 206.
After inflating, driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for getting low
pressure. Check tyre pressure.
Vehicle messages 3 92.
If the tyre pressure must be reduced or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these tyres. Control indicator w
illuminates. For the further three tyres the system remains operational.
The use of commercially-available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor; replacevalve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition according tyre information label or
tyre pressure chart 3 206, and select
the according setting in the menu Tire
Load in the Driver Information Centre,
Vehicle Information Menu 3 86.

Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
12 mph. In this case $ can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process a warning message is
displayed in the Driver Information
Centre.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving tyre temperature and pressure increase.The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than
2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
192Vehicle care
After the underbody is washed, checkthe underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Rear carrier system
Clean the rear carrier system with a
steam-jet or high-pressure jet cleaner
at least once a year.
Operate the rear carrier system
periodically if not in regular use, in
particular during winter.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light- coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.
