The yellow tire pressure monitor warning lamp (pressure loss/malfunction) is lit.
The tire pressure monitor has detected a loss of pressure in at least one of the tires.
G WARNING
Tire pressures that are too low pose the following hazards: R they may burst, especially as the load and vehicle speed increase.
R they may wear excessively and/or unevenly, which may greatly impair tire trac-
tion.
R the driving characteristics, as well as steering and braking, may be greatly
impaired.
There is a risk of an accident.

General notes
The multimedia system section in this Opera-
tor's Manual describes the basic principles for
operation. More information can be found in the Digital Operator's Manual. Important safety notes
G
WARNING
If you operate information systems and com-
munication equipment integrated in the vehi- cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle. There is a risk of an acci-
dent.
Only operate this equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle 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 yield signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rules and regulations
The multimedia system may give incorrect nav-
igation recommendations if the actual street/
traffic situation does not correspond with the
digital map's 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. Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use this feature instead of con-
sulting the map display for directions. Looking
at the icons or map display can distract you from
traffic conditions and driving, and increase the
risk of an accident.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equip-
ment and meets the FCC radio frequency (RF)
Exposure Guidelines in Supplement C to OET65.
This equipment has very low levels of RF energy that is deemed to comply without maximum
permissive exposure evaluation (MPE). How-
ever, it is recommended to install it at a distance
of at least 8 inches (approx. 20 cm) between the
radiation source and a person's body (not
including limbs such as hands, wrists, feet and
legs). G
WARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop. 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. Function restrictions

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, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
DANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the tail- gate is open while 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 tailgate. Never drive with the tailgate
open. 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 burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occupants and luggage/cargo.
Do not exceed the load limit or permitted grossvehicle weight rating (GVWR) for your vehicle.
The gross load limit and the GVWR are specified
on the vehicle identification plate on the B-pillar
of the driver's door (Y page 362).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and rear axles. The specifications for GVWR and GAWR
are on the vehicle identification plate on the B-
pillar of the driver's door (Y
page 362).
Observe the notes on loading the vehicle
(Y page 362).
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a
load:
R Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
R The cargo compartment is the preferred place
to carry objects.
R Position heavy loads as far forward as possi-
ble and as low down in the cargo compart-
ment as possible.
R The load must not protrude above the upper
edge of the seat backrests.
R Always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place.
R Always place the load behind unoccupied
seats if possible.
R Use the cargo tie-down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of the load.
R Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges for
protection. Stowage spaces
Important safety notes G
WARNING
If you transport objects in the vehicle interior and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction. Stowage areas

anchorages, the Top Tether anchorages could be pulled out during braking, abrupt changes
in direction or in the event of an accident. The load could slip, tip over or be flung around and
thereby hit vehicle occupants. There is a risk
of injury.
Only use the cargo tie down rings when secur-
ing a load.
Observe the following notes on securing loads: R Secure the load using the cargo tie-down
rings.
R Distribute the load on the cargo tie-down
rings evenly.
R Do not use elastic straps or nets to secure a
load, as these are only intended as an anti-slip protection for light loads. R
Do not route tie-downs across sharp edges or
corners.
R Pad sharp edges for protection. There are four cargo tie-down rings

cargo compartment.
Bag hook G
WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of lug-
gage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.
Only hang light objects on the bag hooks.
Never hang hard, sharp-edged or fragile
objects on the bag hooks.
! The bag hook can bear a maximum load of
