, BAS, the HOLD function and hill start assist are temporarily unavailable.
Adaptive Brake Assist may also have failed.
ATTENTION ASSIST is deactivated.
Self-diagnosis is not yet complete.
G WARNING
The braking performance of the electric motor using recuperative braking may be
either reduced or not effective. If you do not make an additional effort to apply the brake yourself, the braking effect may not be sufficient. If necessary, counteract
the reduced regenerative braking effect by applying the brake yourself.
The brake system continues to function normally, but without the functions listed
above.
The braking distance in an emergency braking situation can thus increase.
If ESP ®
is not operational, ESP ®
is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
X Carefully drive a suitable distance, making slight steering movements at a speed
above 12 mph (20 km/h).
The functions mentioned above are available again when the warning lamp goes
out.
If the warning lamp is still on: X Observe the additional display messages in the multifunction display.
X Drive on carefully.
X Visit a qualified specialist workshop immediately. 00240049

The red restraint system warning lamp is lit while the drive system is running.
The restraint system is malfunctioning.
G WARNING
The air bags or Emergency Tensioning Devices may either be triggered uninten-
tionally or, in the event of an accident, may not be triggered.
There is an increased risk of injury.
X Observe the additional display messages in the multifunction display.
X Drive on carefully.
X Contact a qualified specialist workshop and have the restraint system checked.

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 while driving, you will be distracted from
traffic conditions. You could also lose control of the vehicle. There is a risk of an accident.
Only operate the 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.
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. Function restrictions

Cargo tie-down rings General notes
Observe the following notes on securing loads:
R Observe the loading guidelines (Y page 207).
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.

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
6.6lbs (3kg) and should not be used to secure
a load. 0043
Bag hook Cargo compartment cover
Important safety notes G
WARNING
On its own, the cargo compartment cover
cannot secure or restrain heavy objects,
items of luggage and heavy loads. You could
be hit by an unsecured load during sudden
changes in direction, braking or in the event of an accident. There is an increased risk of
injury or even fatal injury.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping over, e.g. by
using tie downs, even if you are using the
cargo compartment cover.
! When loading the vehicle, make sure that
you do not stack the load in the cargo com-
partment higher than the lower edge of the
side windows. Do not place heavy objects on top of the cargo compartment cover.
! When removing and installing the cargo
compartment cover, ensure that its end caps do not scrape the light-colored parts of the
vehicle.
The cargo compartment cover is located behind the rear bench seat backrest. 212

Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character- istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
You will find information on the maximum roof
load in the "Technical data" section
(Y page 286).
An incorrectly secured roof carrier or roof load
may become detached from the vehicle. You
must therefore ensure that you observe the roof
carrier manufacturer's installation instructions.
