Driving hints  
Control of the vehicle  
Never coast with engine not  
running  
Many systems will not function in this  
situation (e.g. brake servo unit, power  
steering). Driving in this manner is a  
danger to yourself and others.  
Starting and operating  
New vehicle running-in  
Do not brake unnecessarily hard for  
the first few journeys.  
Steering  
If power steering assist is lost  
because the engine stops or due to a  
system malfunction, the vehicle can  
be steered but may require increased  
effort.  
During the first drive, smoke may  
occur because of wax and oil  
evaporating off the exhaust system.  
Park the vehicle in the open for a  
while after the first drive and avoid  
inhaling the fumes.  
During the running-in period, fuel and  
engine oil consumption may be  
higher.  
All systems function during an  
Autostop.  
Stop-start system 3 156.  
Idle boost  
Additionally, the cleaning process of  
the exhaust filter may take place more  
often.  
If charging of the vehicle battery is  
required due to battery condition, the  
power output of the generator must  
be increased. This will be achieved by  
an idle boost which may be audible.

A warning message also appears  
when exhaust filter has reached the  
maximum filling level. Start cleaning  
process immediately to avoid  
damage to the engine.  
Automatic cleaning process  
Engine exhaust  
The exhaust filter system filters soot  
particles out of the exhaust gases.  
The system includes a self-cleaning  
function that runs automatically  
during driving without any notification.  
The filter is cleaned by periodically  
burning off the soot particles at high  
temperature. This process takes

conditions and may take up to  
9 Danger  
Engine exhaust gases contain  
poisonous carbon monoxide,  
which is colourless and odourless  
and could be fatal if inhaled.  
If exhaust gases enter the interior  
of the vehicle, open the windows.

rectified by a workshop.  
Activate self-cleaning process  
Cleaning process is completed more  
quickly at high engine speeds and  
loads. Therefore, drive in lower gears  
than normal, and use manual gear

25 minutes. Typically it needs  
between 7 and 12 minutes. Autostop  
is not available and fuel consumption  
may be higher during this period. The  
emission of smells and smoke during  
this process is normal.  
Avoid driving with an open load  
compartment, otherwise exhaust  
gases could enter the vehicle.  
Exhaust filter  
System requires cleaning  
Under certain conditions, e.g. driving  
short distances, the system cannot  
clean itself automatically.  
If cleaning of the filter is required and  
if previous driving conditions did not  
enable automatic cleaning, it will be  
indicated by a warning message in  
the Driver Information Centre.  
The exhaust filter is a particle filter for  
diesel and petrol engines.  
Caution  
If possible, do not interrupt  
cleaning process. Drive until  
cleaning is completed to avoid the  
need for service or repair by a  
workshop.  
162  
Driving and operating  
Vehicles with petrol engine  
To activate cleaning process,  
continue driving, keep engine speed  
above 2500 rpm. Shift down if  
necessary.  
Drive dynamically at different engine  
speeds. Use engine brake for  
deceleration, if possible.  
In the event of misfiring, uneven  
engine running, a reduction in engine  
performance or other unusual  
problems, have the cause of the fault  
rectified by a workshop as soon as  
possible. In an emergency, driving  
can be continued for a short period,  
keeping vehicle speed and engine  
speed low.  
Cleaning process not possible  
If cleaning is not possible for any  
reason, control indicator Z  
illuminates and a warning message  
appears in the Driver Information  
Centre. Engine power may be  
reduced. Seek the assistance of a  
workshop immediately.  
Keep on driving until self-cleaning  
operation is complete and the display  
message disappears.  
Catalytic converter  
AdBlue  
General information  
The selective catalytic reduction  
(BlueInjection) is a method to  
substantially reduce the nitrogen  
oxides in the exhaust emission. This  
is achieved by injecting a Diesel  
Exhaust Fluid (DEF) into the exhaust  
system. The ammonia released by  
the fluid reacts with nitrous gases  
(NOx) from the exhaust and turns it  
The catalytic converter reduces the  
amount of harmful substances in the  
exhaust gases.  
Vehicles with diesel engine  
To activate cleaning process,  
continue driving, keep engine speed  
above 2000 rpm, ideally and  
continuously around 2500 rpm. Shift  
down if necessary.  
Keep on driving until self-cleaning  
operation is complete and the display  
message disappears.  
Caution  
Fuel grades other than those listed  
on pages 3 211, 3 278 could  
damage the catalytic converter or  
electronic components.  
Unburnt petrol will overheat and  
damage the catalytic converter.  
Therefore avoid excessive use of  
the starter, running the fuel tank  
dry and starting the engine by  
pushing or towing.

certain value, warnings similar to the  
range warnings will be displayed in  
the Driver Information Centre.  
Requests to have the exhaust system  
checked and finally the  
announcement of the prevention of  
an engine restart are displayed.  
These restrictions are a legal  
requirement.  
Whenever a filling pump with a  
nozzle for passenger cars is not  
available at a filling station, use only  
AdBlue bottles or canisters with a  
sealed refill adapter for refilling, to  
prevent splashback and overspill,  
and in order to ensure that the fumes  
from the tank are captured and do  
not emerge. AdBlue in bottles or  
canisters is available in many filling

Brake preparation system  
When approaching a vehicle ahead  
so quickly that a collision is likely, the  
brake preparation system slightly  
pressurises the brakes. This reduces  
the response time, when a manual or

Emergency automatic braking  
9 Warning  
9 Warning  
After activation of brake preparation  
system and just before the imminent  
collision, this function automatically  
applies limited braking to reduce the  
impact speed of the collision or  
prohibit a crash. Depending on the  
situation, the vehicle may  
automatically brake moderately or  
hard. This front automatic braking can  
only occur if a vehicle ahead is  
detected, indicated by the vehicle  
ahead indicator A 3 186.  
If equipped only with front camera the  
system operates up to a speed of  
50 mph.  
Below a speed of 25 mph the system  
can apply full braking.  
Emergency automatic braking may  
slow the vehicle to a complete stop to  
try to avoid a potential crash. If this  
happens, emergency automatic  
braking may engage the electric  
parking brake to hold the vehicle at a  
stop. To release press the electric  
parking brake button or firmly press  
the accelerator pedal.  
Emergency automatic braking is  
an emergency crash preparation  
feature and is not designed to  
avoid crashes. Do not rely on the  
system to brake the vehicle.  
Emergency automatic braking will  
not brake outside of its operating  
speed range and only responds to  
detected vehicles.  
Active emergency braking is not  
designed to apply hard  
autonomous braking or to  
automatically avoid a collision. It is  
designed to reduce the vehicle  
speed before a collision. It may not  
react for pedestrians or animals.  
After a sudden lane change, the  
system needs a certain time to  
detect the next preceding vehicle.  
The complete attention of the  
driver is always required while  
driving. The driver shall always be  
ready to take action and apply the  
brakes and steer to avoid  
collisions. The system is designed  
to work with all occupants wearing  
their seat belts.  
Forward looking brake assist  
In addition to the brake preparation  
system and emergency automatic  
braking, the forward looking brake  
assist function makes the brake assist  
more sensitive. Therefore, pressing  
the brake pedal less strongly results  
in immediate hard braking. This  
function helps the driver brake  
quicker and harder before the  
imminent collision.  
Intelligent Brake Assist  
If the vehicle is equipped with radar  
sensor Intelligent brake assist may  
activate when the brake pedal is  
applied quickly by providing a boost  
to braking based on the speed of  
approach and distance to a vehicle  
ahead.  
If equipped only with front camera the  
system operates up to a speed of  
52 mph.  
Driving and operating  
191  
Minor brake pedal pulsations or pedal  
movement during this time is normal  
and the brake pedal should continue  
to be applied as needed. Intelligent  
brake assist will automatically  
disengage only when the brake pedal  
is released.  
We recommend to deactivate the  
system or set it to alert only in the  
following cases:

9 Warning  
Intelligent brake assist may  
increase vehicle braking in  
situations when it may not be  
necessary. You could block the  
flow of traffic. If this occurs, take  
your foot off the brake pedal and  
then apply the brakes as needed.

9 Danger  
Fuel is flammable and explosive.  
No smoking. No naked flames or  
sparks.  
If you can smell fuel in your  
vehicle, have the cause of this  
remedied immediately by a  
workshop.  
A label with symbols at the fuel filler  
flap is indicating the allowed fuel  
types. In Europe the pump nozzles of  
the filling stations are marked with  
these symbols. Refuel only the  
allowed fuel type.  
The fuel filler flap can only be opened  
if the vehicle is unlocked. Release the  
fuel filler flap by pushing the flap.  
The fuel filler cap can be retained in  
the bracket on the fuel filler flap.  
Place the nozzle in straight position to  
the filler neck and press with slight  
force to insert.  
Petrol and Diesel refuelling  
To open, turn the cap slowly  
anticlockwise.  
Caution  
To refuel, switch on pump nozzle.  
After the automatic cut-off, the tank  
can be topped up by operating the  
pump nozzle a maximum of two more  
times.  
In case of misfuelling, do not  
switch on ignition.  
Fuel filler flap is located at right rear  
side of the vehicle.  
Caution  
Wipe off any overflowing fuel  
immediately.  
Driving and operating  
215  
To close, turn the fuel filler cap  
clockwise until it clicks.  
After topping-up, clean funnel from  
fuel remains and stow it away.  
Trailer hitch  
Close the flap and engage.  
General information  
Fuel filler cap  
Only use genuine fuel filler caps.  
Diesel-engined vehicles have special  
fuel filler caps.  
Only use towing equipment that has  
been approved for your vehicle.  
Entrust retrofitting of towing  
Misfuel inhibitor  
9 Warning  
equipment to a workshop. It may be  
necessary to make changes that  
affect the cooling system, heat  
shields or other equipment.  
Do not try to open the flap of the  
fuel filler neck manually on  
vehicles with misfuel inhibitor.  
The bulb outage detection function for  
trailer brake light cannot detect a  
partial bulb outage. E.g. in case of  
four bulbs with a power of 5 W each,  
the function only detects light outage  
when only a single 5 W bulb remains  
or none remain.  
Fitting of towing equipment could  
cover the opening of the towing eye.  
If this is the case use the coupling ball  
bar for towing. Always keep the  
coupling ball bar in the vehicle when  
not in use.  
Disregarding this could lead to  
trapping of the fingers.  
The misfuel inhibitor ensures that the  
flap of the fuel filler neck can only be  
opened by using the suitable fuel  
nozzle or a funnel for emergency  
refilling.  
In case of an emergency, refill with a  
canister. A funnel must be used to  
open the cap of the filler neck.  
The funnel may be stowed in the load  
compartment or the glovebox.  
Place the funnel in straight position to  
the filler neck and press with slight  
force to insert.

Driving and operating  
The permissible gross train weight  
must not be exceeded. This weight is  
specified on the identification plate  
3 274.  
Driving characteristics and  
towing tips  
Trailer towing  
Trailer loads  
Before attaching a trailer, lubricate  
the coupling ball. However, do not do  
so if a stabiliser, which acts on the  
coupling ball, is being used to reduce  
snaking movements.  
The permissible trailer loads are  
vehicle and engine-dependent  
maximum values which must not be  
exceeded. The actual trailer load is  
the difference between the actual  
gross weight of the trailer and the  
actual coupling socket load with the  
trailer coupled.  
The permissible trailer loads are  
specified in the vehicle documents. In  
general, they are valid for gradients  
up to 12%.  
The permissible trailer load applies  
up to the specified incline and at sea  
level. Since engine power decreases  
as altitude increases due to the air  
becoming thinner, therefore reducing  
climbing ability, the permissible gross  
train weight also decreases by 10%  
for every 1000 m of altitude. The  
gross train weight does not have to be  
reduced when driving on roads with  
slight inclines (less than 8%, e.g.  
motorways).  
Vertical coupling load  
The vertical coupling load is the load  
exerted by the trailer on the coupling  
ball. It can be varied by changing the  
weight distribution when loading the  
trailer.  
The maximum permissible vertical  
coupling load is specified on the  
towing equipment identification plate  
and in the vehicle documents. Always  
aim for the maximum load, especially  
in the case of heavy trailers. The  
vertical coupling load should never  
fall below 25 kg.  
During trailer towing do not exceed a  
speed of 50 mph. A maximum speed  
of 60 mph is only appropriate if an  
oscillation damper is used and the  
permissible gross trailer weight does  
not exceed the vehicle's curb weight.  
For trailers with low driving stability  
and caravan trailers, the use of an  
oscillation damper is strongly  
recommended.  
If the trailer starts snaking, drive more  
slowly, do not attempt to correct the  
steering and brake sharply if  
necessary.  
When driving downhill, drive in the  
same gear as if driving uphill and  
drive at a similar speed.  
Rear axle load  
When the trailer is coupled and the  
towing vehicle fully loaded, the  
permissible rear axle load (see  
identification plate or vehicle  
documents) may be exceeded by  
40 kg. If the permissible rear axle load  
is exceeded, a maximum speed of  
60 mph applies.  
Adjust tyre pressure to the value  
specified for full load 3 283.

Driving and operating  
Stow the coupling ball bar in the bag  
and secure by fixing the strap through  
the rear right lashing eye. Wrap  
around twice and tighten the strap to  
secure the bag.  
Trailer stability assist  
If the system detects snaking  
movements, engine power is reduced  
and the vehicle/trailer combination is  
selectively braked until the snaking  
ceases. While system is working keep  
steering wheel as still as possible.  
Trailer stability assist is a function of  
the Electronic Stability Control 3 173.
