BAS PLUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic.
BAS PLUS may not detect narrow vehicles
such as motorcycles and vehicles driving on
a different line.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked at a Mercedes-Benz Service Centre.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor system, the braking
system remains available with full brake
boosting effect and BAS. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS *,the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 96).ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the äwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the ä warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
! Vehicles with 4MATIC* may not be towed
with the front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ESP ®
trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect when the trailer begins to lurch.

i If the battery voltage is too low, the seat
heating may switch off. Folding bench seat* in the luggage
compartment (Estate)
The folding bench seat in the luggage com-
partment is only suitable for persons no more
than 1.40 m tall and weighing a maximum of
50 kg.
The maximum permissible weight may be
reduced by extensive optional extras, vehicle
load and trailer towing. Observe the maxi-
mum gross vehicle weight and the permissi-
ble axle load, which can be found on the vehi-
cle identification plate (Y page 332).The combined luggage cover and net must be
fitted if you are using the folding bench seat. G
Risk of injury
The rear seat backrests must be locked in the
upright position if you are using the folding
bench seat in the luggage compartment.
Only drive when the head restraints in the
folding bench seat are adjusted to the correct
position. Make sure that the centre of the
head restraint supports the seat occupant's
head at about eye level. This can reduce the
risk of injury to a child in the event of an acci-
dent.
Ensure that the seat belt sits correctly on the
body and that it is engaged in the seat belt
buckle.
Never leave children unsupervised in the vehi-
cle. This applies even if they are secured in a
child restraint system.
Secure children as recommended; see "Chil-
dren in the vehicle" section. G
Risk of injury
Only replace damaged covers with genuine
covers.
Make sure that items of luggage and other
objects are sufficiently secured in the luggage
compartment.
Otherwise, the load could injure someone in
the event of sharp braking, a sudden change
in direction or an accident.

passenger
The 7 seat belt warning lamp in the instru-
ment cluster reminds you that all occupants
should fasten their seat belts. It is either lit
continuously or flashes. Additionally, there
may be a warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases as soon as the driver
and front passenger have fastened their seat
belts.
For certain countries only: regardless of
whether the driver or the front passenger
already have their seat belt fastened, the
7 seat belt warning lamp lights up for six
seconds after the engine has been started. It
then goes out if both the driver and the front
passenger have fastened their seat belt.

belt warning lamp (Y page 286). Belt height adjustment
You can adjust the seat belt height on the
driver's seat and the front-passenger seat.
Estate: you can also adjust the belt height on
the outer rear bench seats.

Parking
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle with the key removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances come into contact
with easily ignitable material such as dry grass
or petrol. Otherwise, the flammable material
may ignite and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied
R on vehicles with manual transmission,
engage first gear or reverse gear
R on vehicles with automatic transmission*,
the transmission must be in position Pand
the key must be removed from the ignition
lock
R on steep uphill or downhill gradients, turn
the front wheels towards the kerb
Parking brake X
To apply: depress parking brake ;firmly.

Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking will then require significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.
