90Instruments and controlsCaution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays the level in the fuel tank.
Control indicator o illuminates if the
level in the tank is low.
Never run the fuel tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified fuel tank capacity.
Engine coolant temperature
gauge
Displays the coolant temperature.
50:engine operating temperature
not yet reached90:normal operating temperature130:temperature too high
Control indicator o illuminates if
coolant temperature is too high. Switch off engine immediately.
Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
Engine oil level monitor
The state of the engine oil level is
displayed in the Driver Information
Centre for a few seconds following
the service information after switching
on the ignition.
A proper state of oil level is indicated
by a message.
If oil level is low, I flashes and a
message is indicated, accompanied
by the H indicator. Confirm oil level
by using the oil dipstick and top up
engine oil respectively.
Engine oil 3 203.
A fault of measurement is indicated
by a message. Check oil level
manually by using the dipstick.
96Instruments and controlsIlluminates when the engine is
running
Stop, switch off engine.Caution
Coolant temperature too high.
Check coolant level immediately
3 204.
If there is sufficient coolant, consult a workshop.
Preheating
! illuminates yellow.
Preheating of diesel engine is
activated. Only activates when
outside temperature is low. Start the
engine when control indicator
extinguishes.
Starting the engine 3 137.
Exhaust filter % or H illuminates yellow.
The exhaust filter requires cleaning.
Continue driving until the control
indicator extinguishes.
Illuminates temporarily Start of saturation of the exhaust filter.
Start cleaning process as soon as
possible by driving at a vehicle speed
of at least 40 mph.
Illuminates constantlyIndication of a low additive level. Seek
the assistance of a workshop.
Exhaust filter 3 142.
AdBlue
Y flashes or illuminates yellow.
Illuminates yellow The remaining driving range is
between 370 mph and 1500 mph.
Flashes yellow
The remaining driving range is
between 0 and 370 mph.AdBlue level is low. Refill AdBlue
soon to avoid prevention of the
engine start. Up to 10 l of AdBlue can
be added.
AdBlue 3 143.
Deflation detection system
w illuminates or flashes yellow.
Illuminates
Tyre pressure loss in one or more
wheels. Stop immediately and check
tyre pressure.
Flashes
Fault in system. Consult a workshop.
Deflation detection system 3 221.
Engine oil pressure
I illuminates red.
Illuminates when the ignition is
switched on and extinguishes shortly
after the engine starts.
Vehicle care201Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Cold protection covers
In order to prevent the accumulation
of snow at the radiator cooling fan, it is recommended to install removable
protection covers.
The protection covers must be
professionally installed, consult a
workshop.
Caution
The protection covers must be removed when one of the
following conditions occur:
● The ambient temperature is abbove 10 °C.
● When the vehicle is towed.
● The vehicle is driven at speeds
above 75 mph.
Vehicle storage
Storage for a long period of timeIf the vehicle is to be stored for several
months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, well ventilated place. Engage first or
reverse gear or set selector lever to P. Prevent the vehicle from
rolling.
● Do not apply the parking brake.● Open the bonnet, close all doors and lock the vehicle.
● Disconnect the clamp from the negative terminal of the vehicle
battery. Note that all systems are
not functional, e.g. anti-theft
alarm system.
Putting back into operation When the vehicle is to be put back into
operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Initialize the power
windows 3 39.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the engine oil level.
● Check the coolant level.
● Fit the number plate if necessary.
204Vehicle careWe recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.
Capacities 3 254.
Fit the cap on straight and tighten it.
Engine coolant
The factory filled coolant provides
freeze protection down to approx.
-37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 242.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
MIN mark. Top up if the level is low.
9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
Vehicle care205the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 242.
Brakes In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe DANGER and MAX marks.
If fluid level is below DANGER seek
the assistance of a workshop.
Brake and clutch fluid 3 242.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
