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.

attention to road and traffic conditions. Do not continue driving
under any circumstances.
XSecure the vehicle against rolling away (Ypage 153).

(Canada only) warning
lamps are lit while the

ABS (Anti-lock Braking System) is deactivated due to a malfunc-
tion. Therefore, BAS (Brake Assist), COLLISION PREVENTION

function and hill start assist are also deactivated, for example.
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 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 an increased risk of skidding and an accident.

If the ABS control unit is malfunctioning, other systems may also
not be available, e.g. the navigation system.

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 26).
Loading guidelines
GWARNING
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.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load:
RNever exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle
identification plate on the B-pillar of the
driver's door.
RThe cargo compartment is the preferred
place to carry objects.
RPosition heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible.
RThe load must not protrude above the
upper edge of the seat backrests.
RAlways place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
RAlways place the load behind unoccupied
seats if possible.
RUse the cargo tie-down rings and the parcel
nets to transport loads and luggage.
RUse cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
RHook in the cargo net when loading.
RThe maximum load capacity of the stowage
well under the cargo compartment floor is
55 lbs (25 kg).
RSecure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection.
!Do not position the load on one part of the
folding cargo compartment floor only. The
maximum load capacity of the folding cargo
compartment floor is 220 lbs (100 kg). Dis-
tribute the weight evenly to avoid damaging
the cargo compartment floor. Place a solid
board under the load if necessary. Please
note that the load on the cargo compart-
ment floor will be increased when the load
is lashed down.

Important safety notes
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction.
242Stowage areas
Stowage and features

RAlways stow objects so that they cannot be
thrown around in such situations.
RAlways make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces before
starting a journey.
RStow and secure objects that are heavy,
hard, pointed, sharp-edged, fragile or too
large in the cargo compartment.
Observe the loading guidelines (Ypage 242).
