The tyre pressure monitor has detected a loss of pressure in at least one of the
tyres.
G WARNING
Underinflated tyres pose the following risks:
R the tyres may burst, especially as the load and vehicle speed increase
R the tyres may wear excessively and/or unevenly, which may greatly impair tyre
traction
R the driving characteristics, as well as steering and braking, may be greatly
impaired
There is a risk of an accident.
X Stop the vehicle without making any sudden steering or braking manoeuvres.
Pay attention to the traffic conditions as you do so.

General notes
The section on the multimedia system in this
manual describes the basic principles for oper-
ation. More information can be found in the Dig-
ital Owner's Manual. Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the multimedia system.
The multimedia system calculates the route to
the destination without taking the following into
account, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rules and regulations
The multimedia system may give incorrect driv-
ing recommendations if the actual road/traffic
situation does not correspond with the digital
map data.
For example:
R a diverted route
R the road layout or the direction of a one-way
street has been changed
For this reason, you must always observe road
and traffic rules and regulations during your
journey. Road and traffic rules and regulations
always have priority over multimedia system
driving recommendations. G
WARNING
Modifications to electronic components, their software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic components carried out at a qualified special-
ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid. Function restrictions
For safety reasons, some functions are restric-
ted or unavailable while the vehicle is in motion.
You will notice this, for example, because either you will not be able to select certain menu items
or a message will appear to this effect. Operating system
Overview
General notes Wearing polarised sunglasses may impair your
ability to read the display.
The display has an automatic temperature-con-
trolled switch-off feature. The brightness is
automatically reduced if the temperature is too
high. If necessary, the display may temporarily
switch off completely.
Cleaning instructions !
Do not touch the display. The display has a
very sensitive high-gloss surface; there is a
risk of scratching. If you have to clean the
screen, however, use a mild cleaning agent
and a soft, lint-free cloth. 284

General notes Correct functioning of the navigation system
depends, amongst other things, on GPS recep-
tion. In certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
multi-storey car parks.

WARNING
SD cards are small parts. They can be swal-
lowed and cause choking. This poses an
increased risk of injury or even fatal injury.
Keep the SD card out of the reach of children. If a SD card is swallowed, seek medical atten-
tion immediately.
! If you are no longer using the SD card, you
should remove it and store it outside the vehi-
cle. High temperatures can damage the card.
Inserting an SD card
The SD card slot is located in the stowage com- partment under the armrest.
X Insert the SD card into the SD card slot until
the SD card engages. The side with the con-
tacts must face downwards.

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the boot
lid is open when the engine is running, espe-
cially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the boot lid. Never drive with the boot lid
open. G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
note the following when transporting a load:
R never exceed the maximum gross vehicle
weight or the permissible axle loads for the
vehicle (including occupants).
R the boot is the preferred place to store
objects.
R position heavy loads as far forwards as pos-
sible and as low down in the boot as possible. R
the load must not protrude above the upper
edge of the seat backrests.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently strong and
wear-resistant lashing material. pad sharp
edges for protection.
i Lashing material is available at any qualified
specialist workshop. Stowage compartments
Important safety notes G
WARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cupholders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. There is a risk of injury, particularly in the event of sudden
braking or a sudden change in direction.
R Always stow objects so that they cannot be
thrown around in such situations.
R Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
R Close the lockable stowage spaces before
starting a journey.
R Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the boot.

bench seat
Important safety notes G
WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for- wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt cannot protect as intended and
could result in additional injury.
R Objects or loads in the boot cannot be
restrained by the seat backrest.
This poses an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged before every trip.
! When folding the rear seat backrest for-
wards, ensure that there are no items lying on the seat cushions. These items could other-
wise be damaged or could themselves dam-
age the rear seats.
Observe the loading guidelines (Y page 296).
The left-hand and right-hand rear seat backrests can be folded down separately to increase the
boot capacity. 298

Cup holders
Important safety notes G
WARNING
The cup holder cannot secure a drinks con-
tainer in place during a journey. If you use a
cup holder during a journey, the drinks con-
tainer could be flung around and liquid could
be spilt. Vehicle occupants could come into
contact with the liquid and, in particular, be
scalded by hot liquid. You could be distracted
from the traffic situation and lose control of
the vehicle. There is a risk of an accident and
injury.
Only use the cup holder when the vehicle is
stationary. Only place containers of a suitable size in the cup holder. Seal the container, in
particular when it contains hot liquid. G
