Warning and indicator lamps in the instrument cluster
General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Therefore, some
indicator and warning lamps may light up or flash temporarily. This behavior is non-critical.
These warning and indicator lamps only indicate a malfunction if they light up or flash after the
drive system is started or during a journey.

lamps are lit while the
drive system is running.
ABS is temporarily unavailable. Therefore, BAS, COLLISION PRE-
VENTION ASSIST PLUS, ESP®, EBD (electronic brake force distri-
bution), the HOLD function and hill start assist are also deactiva-
ted, for example.
Possible causes are:
RSelf-diagnosis is not yet complete.
RThe on-board voltage may be insufficient.
ATTENTION ASSIST is deactivated.
GWARNING
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 regen-
erative braking effect by applying the brake yourself.
The brake system continues to function normally, but without the
functions listed above. The front and rear wheels could therefore
lock if you brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP
®is not operational, ESP®is unable to stabilize the vehicle.
There is a risk of an accident.
XCarefully drive a suitable distance, making slight steering move-
ments 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:
XObserve the additional display messages in the multifunction
display.
XDrive on carefully.
XVisit a qualified specialist workshop immediately.

Securing cargo
Cargo tie-down rings
General notes
Observe the following notes on securing
loads:
RObserve the loading guidelines
(
Ypage 242).
RSecure the load using the cargo tie-down
rings.
RDistribute the load on the cargo tie-down
rings evenly.
RDo not use elastic straps or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
RDo not route tie-downs across sharp edges or corners.
RPad sharp edges for protection. Cargo compartment
:Cargo tie-down rings
Bag hook
GWARNING
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.

Cargo compartment cover
Important safety notes
GWARNING
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.
Extending/retracting the cargo com-
partment cover
XTo extend: pull the cargo compartment
cover back by grab handle :and clip it into
retainers ;on the left and right.
XTo retract: unhook the cargo compartment
cover from retainers ;on the left and right
and guide it forwards by grab handle :
until it is fully retracted.
Installing/removing the cargo compart-
ment cover
XTo remove: make sure that the cargo com-
partment cover is rolled up.
XPush in the end cap of cargo compartment
cover :in the direction of the arrow on the
right or left-hand side using grip =on the

Roof carrier
Important safety notes
GWARNING
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
(
Ypage 338).
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.
Attaching the roof carrier
XOpen covers :carefully in the direction of
the arrow.
XFold covers :upwards.
XOnly secure the roof carrier to the anchor-
age points under covers :.
XObserve the manufacturer's installation
instructions.
Features
Cup holder
Important safety notes
GWARNING
The cup holder cannot hold a container secure
whilst traveling. If you use a cup holder whilst
traveling, the container may be flung around
and liquid may be spilled. The vehicle occu-
pants may come into contact with the liquid
and if it is hot, they may be scalded. You may
be distracted from the traffic conditions and
you could 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 use the cup holder for con-
tainers of the right size. Always close the con-
tainer, particularly if the liquid is hot.
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
