Problems with the fuel and fuel tank
If your vehicle is losing fuel, the fuel lines or thefuel tank are defective.
XTurn the SmartKey immediately to position 0
in the ignition lock and remove it.
XDo not restart the engine under any circum-
stances.
XConsult a qualified specialist workshop.
If the fuel tank has been run dry, after refueling
carry out the following steps:
XBefore starting the engine: switch on the igni-
tion three or four times.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 117).
The % preglow indicator lamp in the instru-
ment cluster lights up briefly.
XOnce the %preglow indicator lamp goes
out, turn the SmartKey to position 3in the
ignition lock and release it as soon as the
engine is running.
You can start the diesel engine without preglow
when the engine is warm.
Diesel Exhaust Fluid (DEF)
Important safety notes
!Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or
thin it with tap water. The exhaust gas after-
treatment may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of additives
or tap water leads to the loss of the New
Vehicle Limited Warranty.
!If DEF comes into contact with a painted or
aluminum surface, wash the surface off
immediately with plenty of water.
!DEF is not a diesel additive and must not be
mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of DEF
will not be covered by the New Vehicle Limi-
ted Warranty.
iIf the outside temperature is below 12 ‡
(Ò11 †) it may be difficult to top up. If the DEF
is frozen and there is an active warning indi- cator, topping up may not be possible. Park
the vehicle in a warm place, e.g. in a garage,
until the DEF has become liquid again. Top-
ping up is then possible again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the tank activated) and then stop the vehicle
for at least 30 seconds. The level is then
shown correctly.
You will find further information on DEF in the
"Service products" section (
Ypage 273).

126Refueling
Driving and parking

Always park your vehicle safely and according to
legal requirements and secure it against rolling
away.
To ensure that the vehicle is properly secured
against rolling away unintentionally:
Rthe parking brake must be firmly applied
Rthe selector lever must be in positionPand
the key must be removed from the ignition
lock
Ron steep uphill or downhill gradients, the front
wheels must be turned towards the curb
Rthe rear axle must be secured, e.g. with a
wheel chock, on steep uphill or downhill gra-
dients
Use the wheel chock (
Ypage 129) to do so.
If you leave the vehicle parked for more than
three weeks:
Rconnect the batteries to a trickle charger or
Rdisconnect the vehicle's starter battery or
Rswitch off the electrical system using the bat-
tery main switch (Ypage 116) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con-
dition of charge every three weeks, since
standby power consumption can drain the bat-
tery. If the battery voltage is lower than 12.2 V,
the battery must be charged. Otherwise, the
battery may be damaged by exhaustive dis-
charging.
Be sure to observe the notes on disconnecting
and chargi ng th
e batteries under "Bat-
tery“ (Ypage 223). You can obtain information
about trickle chargers from a qualified specialist
workshop.
Parking brake
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking brake
when the vehicle is stationary.

uation and beready to brake.
GWAR NING
The distance warning function cannot always
clearly identify objects and co mplex traff ic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Alwa ys pay careful attention to the traff icsit-
uation and donot rely solely on the distance
warning function.
Operation
The distance warning function can help you to
minimize the risk of a front-end collision with a
vehicle ahead or reduce the effects of such a
collision. Ifthe distance warning function
detects that there isa risk of a collision, you will
be warned visually and acoustically. Without
your intervention, the distance warning function
cannot prevent a collision.
The distance warning function willissue a warn-
ing at speeds of around 20 mph (30 km/h)or
more if:
Ryou approach a vehicle ahead of you very
quickly. You will then hear an intermittent
warning tone and the red ·warning lamp
in the instrument cluster flashes.
XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action provided it is safe to do
so.
Driving systems139
Driving and parking
Z

If you want the distance warning function to
assist you, the function must be activated and
operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of around 45 mph (70 km/h), the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision, the
system will alert you both visually and acousti-
cally.
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt on the sensors or anything else covering
the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
Activating/deactivating the distance
warning function
When you switch on the engine, the distance
warning function switches on after a few sec-
onds.
XTo deactivate: press theæbutton

Adaptive Brake Assist
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 53).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rto stationary obstacles
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.

Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt on the sensors or anything else covering
the sensors
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rnarrow and short vehicles, e.g. motorcycles
or bicycles
Rvery wide lanes
Rnarrow lanes
Rvehicles not driving in the middle of their lane
Rbarriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area approx-
imately 10 ft (3.0 m) behind your vehicle and
approximately 1.6 ft (0.5 m) to 11.5 ft (3.5 m)
each side of it. The monitoring range behind the
vehicle may also be larger depending on the sit-
uation.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane. Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, for exam-
ple trucks, for a prolonged time.
The two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear-moun- ted cycle racks or overhanging loads. Following
a severe impact or in the event of damage to the
bumper, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work prop- erly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
:Yellow indicator lamp and red warning lamp
If yellow indicator lamp :lights up:
Ryou are driving at less than 20 mph (30 km/h)

RBlind Spot Assist is malfunctioning
Blind Spot Assist is active from a speed of
20 mph (30 km/h). If a vehicle is detected in the
blind spot monitoring range, red warning
lamp :on the corresponding side lights up.
This warning occurs when a vehicle enters the
blind spot monitoring range from behind or from
the side. When you overtake a vehicle, the warn- ing only occurs if the difference in speed is less
than 14 mph (22 km/h).
Yellow indicator lamp :goes out if reverse gear
is engaged. Blind Spot Assist is then deactiva-
ted.

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of a camera at the top of
the windshield. Lane Keeping Assist detects
lane markings on the road and warns you before
you leave your lane unintentionally.
:Lane Keeping Assist camera
Lane Keeping Assist supports you from speeds
of approximately 40 mph(60 km/h).
If Lane Keeping Assist detects lane markings,
the à indicator lamp in the instrument clus-
ter lights up green. Lane Keeping Assist is opera-
tional.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of accident
nor override the laws of physics. Lane Keeping
Assist cannot take into account road, weather or traffic conditions. Lane Keeping Assist is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, braking in
good time and for staying in your lane.

DSR (Downhill Speed Regulation)
Important safety notes
Observe the notes on braking in the section on
"Driving and parking". If you fail to adapt your
driving style or you are inattentive, DSR can nei-
ther reduce the risk of accident nor override the laws of physics. DSR cannot take road, weather
and traffic conditions into account. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time.
General notes
DSR supports you with the LOW RANGE trans-
mission ratio when you are driving downhill off-
road and on construction sites. DSR maintains a
preset speed for you on downhill gradients by
applying the brakes as required. Maintaining the
speed is dependent on the road surface condi-
tions and the downhill gradient and cannot
therefore be guaranteed in all situations.
You can set the speed to between 2.5 mph
(4 km/h) and 11 mph (18 km/h) using the brake
and accelerator pedals or the cruise control
lever.
RIf the vehicle is stationary, or its speed is less
than 2.5 mph (4 km/h) the speed is set to
2.5 mph (4 km/h).
RIf you drive faster than 11 mph (18 km/h) off-
road, DSR switches to standby mode. DSR
remains activated, but does not brake auto-
matically.
RIf you drive downhill slower than 11 mph
(18 km/h), DSR sets the speed to the previ-
ously set speed.
RDSR switches off automatically if you drive
faster than 28 mph (45 km/h).
