Display priorities
Advanced parking assist indication in the DIC can be inhibited by vehicle
messages with a higher priority. After
approving the message by pressing
the SET/CLR button on the turn signal
lever, advanced parking assist
instructions appear again and the
parking manoeuvre can be continued.
Deactivation
The system is deactivated by:
■ a long press of button D
■ parking manoeuvre successfully ended
■ driving faster than 18 mph during parking slot search
■ driving faster than 5 mph during parking guidance
■ driver interference on steering wheel detected■ exceeding number of maximumgear changes: eight cycles when
parallel parking or five cycles when
perpendicular parking
■ switching off the ignition
Deactivation by the driver or by the
system during manoeuvring will be
indicated by Parking Deactivated on
the display. Additionally, an acoustic
signal sounds.
Fault
A message appears when:
■ there is a fault in the system
■ the driver did not successfully complete the parking manoeuvre
■ the system is not operational
■ any of the deactivation reasons described above apply
If an object is detected during parking instructions, Stop is indicated on the
display. Removing the object will
resume the parking manoeuvre. If the
object is not removed, the system will
be deactivated. A long press of button
D will activate the system and
search for a new parking slot.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 must 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

Driving and operating165
An 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.
As soon as the 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 indication
Traffic signs are displayed on the
page Traffic sign detection in the
Driver Information Centre. Choose
Vehicle via the Menu button and
select Traffic sign detection with the
adjuster wheel on the turn signal lever
3 93.
When another page on the Driver
Information Centre menu was
selected and then Traffic sign
detection page is chosen again, the
last recognised traffic sign will be displayed.
Alert function
Once activated, speed limit and no
passing signs are displayed as pop-
up alerts in the DIC.

172Driving and operating
The permitted trailer loads apply up tothe specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 % for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving on roads with slight inclines (less than
8 %, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is specified on the identification plate3 226.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (55 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 70 kg for the 5-
door vehicle and 60 kg for the 3-door vehicle, the gross vehicle weight
rating by 55 kg.
If the permitted rear axle load is
exceeded a maximum speed of
60 mph applies. If lower national
maximum speeds are specified for
trailer operation, they must be
complied with.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The coupling ball bar is stowed in a
bag in the spare wheel well and
secured to the lashing eyes in the
load compartment.
When inserting, fit protective cap over
rotary knob with key.
Page 177 of 249
Driving and operating1759Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball
bar
Insert the key in the lock and unlock
the coupling ball bar.
Push the rotary knob onto the
coupling ball bar and rotate right while pressed down until it engages. Pull
out the ball bar downwards.
Insert sealing plug in opening for
coupling ball bar. Fold away socket.
Trailer stability assist If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is selectively braked until the snaking
ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Control 3 145.

Accessories and vehicle
modifications
We recommend the use of genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or
guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps may be damaged.
Vehicle storage
Storage for a long period of time If the vehicle is to be stored for severalmonths:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve the rubber seals.
■ Fill up fuel tank completely.
■ Change the engine oil.
■ Drain the washer fluid reservoir. ■ Check the coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park the vehicle in a dry, well ventilated place. Engage first orreverse gear or set selector lever to P . Prevent the vehicle from rolling.
■ Do not apply the parking brake.

Vehicle care199Wheels and tyresTyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 237.
Tyre size 185/60 R 15 is only
permitted as winter tyre.In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.

Directional tyres must be mounted so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey. Do not forget the spare
wheel.
This also applies to vehicles with tyre pressure monitoring system.
Unscrew the valve cap.
