As
aresult, BAS PLUS may not intervene in all
critical situations. There is arisk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensor soranythin gelse
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R an arrow vehicle travelin ginfront, e.g. a

Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensor schecked at aqualified
specialist workshop. This also applies to
collisions at low speeds where ther eisno
visible damage to the fron tofthe vehicle.
Braking assistance To prevent
acollision with the vehicle in front,
BAS PLUS calculates the brake force
necessary if:
R you approach an obstacle, and
R BAS PLUS has detected arisk of collision
When driving at aspeed under 20 mph
(30 km/h):ify ou depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at aspeed greater than
20 mph (30 km/h):ify ou depress the brake
pedal sharply, BAS PLUS automatically raises
the brake pressure to avalue adapted to the
traffic situation.
If BAS PLUS demands particularly high
braking force, preventative passenger protection measures (PRE-SAFE
®
)a re
activated simultaneously.
X Keep the brake pedal depressed until the
emergenc ybraking situation is over.
ABS prevent sthe wheels from locking.
BAS PLUS is deactivated and the brakes

Pulling away
Automatic transmission G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor
R,t he vehicle could pull away suddenly. There
is ar isk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do
not simultaneously accelerate.
! Ifaw arning tone sounds and the
Release Park. Brake message appears
in the multifunction display,t he parking
brake is still applied. Release the parking
brake.
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position Dor R.
X Release the parking brake (Y page 169).
X Release the brake pedal.
X Carefullyd epress the accelerator pedal.
i It is only possible to shift the transmission
from position Pto the desired position if
you depress the brake pedal. Only then is
the parking lock released. If you do not
depress the brake pedal, you can move the
DIRECT SELECT lever but the parking lock
remains engaged.
i The vehicle locks centrally once you have
pulleda way.The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic
locking feature (Y page 232).
i Upshifts take place at higher engine
speeds after acold start. This helps the
catalytic converter to reach its operating
temperature more quickly. Hill starta
ssist G
WARNING
After ashort time, hill start assist will no
longer brake your vehicle and it could roll
away. There is arisk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for ashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
X Take your foot off the brake pedal.
The vehicle is then held for about asecond.
X Pull away.
Hill start assist will not function if:
R you are pulling away on alevel road or on
ad ownhill gradient.
R the transmission is in position N.
R the parking brake is applied.
R ESP ®

Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped under certain conditions.
The engine start
sautomatically when the
driver wants to pull away again. The ECO

reduce the fuel consumption and emissions
of your vehicle. 150

and, if applicable, the auxiliary heating before
refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is arisk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children. If you or others come into contact with fuel,
observe the following:
R
Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If fuel is swallowed, seek medical
assistance without delay.Don ot induce
vomiting.
R Immediately change out of clothin gwhich

X Remove unnecessary loads.
X Remove roof racks whe nthey are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.

Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment. The possibility of
aserious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, only have work on the engine carried
out by qualified and authorized Mercedes-

The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the

sensor system. DISTRONIC PLUS brakes
automaticallysot hat the set speed is not
exceeded.
Change into alower gear in good time on long
and steep downhill gradients. This is
especially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is arisk
of ac ollision, you will be warned visually and
acoustically.D ISTRONIC PLUS cannot
prevent acollision without your intervention.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately in
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and 120 mph (Canada:
200 km/h). If avehicle is driving in front of
you, it operates in the speed range between
0m ph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
