Important safety notes
G
WARNING
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is 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
WARNING
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol, for
example. Do not park the vehicle on dry grass-
land or harvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be firmly 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 uphill or downhill gradients, turn the
front wheels towards the kerb. Switching off the engine
Important safety notes G
WARNING
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking then requires significantly
greater effort.

General driving tips
Rolling with the engine switched off G
WARNING
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effor tto
steer and brake, and you could therefore lose
control of the vehicle and cause an accident. Driving short distances
! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This may lead to fuel
collecting in the engine oil and cause
engine failure. Therefore, if you frequently
drive short distances, you should take a 20
minute trip on a motorway or rural road at
least every 500km. Brakes
Important safety notes G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or,
on vehicles with automatic transmission,
select shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Heavy and light loads G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constan tslight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a shor twhile. This allows the air-
flow to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a 178

The following function is not operational
in all countries.
DISTRONIC PLU Suses additional information
from your navigation system so that it can
adaptt o certain traffic situations. This is the
case if, while following a vehicle, DISTRONIC
PLUS is active and you:
R approach or drive around a roundabout
R approach a T junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is based on the current
map data in the navigation system. Example: roundabout
The current speed is maintained:
R
approximately 10 seconds before the
roundabout/T junction and approximately
1.5 seconds when driving on a roundabout.
R approximately 12 seconds before reaching
a motorway exit and approximately
4 seconds after the motorway exit.
Afterwards, the vehicle accelerates back to
the set speed you specified.
Stopping G
WARNING
Never get out of the vehicle when DISTRONIC
PLUS is activated. DISTRONIC PLUS must also never be oper-
ated, activated or deactivated by a passenger
or from outside the vehicle.
DISTRONIC PLUS does not replace the park-
ing brake and must not be used for parking.
The DISTRONIC PLUS braking effect is can-
celled and the vehicle can start moving if:
R
DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If DISTRONIC PLUS detects that the vehicle
in front is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle
in front.T he specified minimum distance is
set using the control on the cruise control
lever.
Vehicles featuring automatic transmis-
sion with aselector lever
You will see a warning message in the multi-
function display if DISTRONIC PLUS is acti-
vated and:
