nition is switched on. In order to avoid possible
damage to the engine, please read the following
notes for the different temperature ranges.
Engine cold
If the LEDs are still in the lower range of the dis­
play, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine

loads.

Normal temperature
The LEDs will settle somewhere in the centre of
the display once the engine has reached operat­
ing temperature. If the warning lamp || lights
up in the instrument cluster display, the coolant
temperature is too high

- Additional lights and other accessories in
front of the air inlet reduce the cooling ef­
fect of the radiator. At high outside temper­
atures and high engine loads, there is a risk
of the engine overheating.
- The front spoiler also ensures proper distri­
bution of the cooling air when the vehicle is

moving.
If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Obtain professional
assistance.
® Note
Applies to: vehicles with diesel engine
These engines are so efficient that they may
not reach their full operating temperature in
very cold weather. This is quite normal and no
cause for concern.
Rev counter

The
rev counter indicates the number of engine
revolutions per minute.
The start of the red zone on the dial indicates the
maximum engine speed which may be used brief­
ly in all gears when the engine is warm and after
it has been run in properly. However, it is advisa­
ble to change up a gear or move the selector lev­
er to D/S (or
lift your
foot
off
the accelerator) be­
fore the needle reaches the red zone. •

Note
After the engine is stopped, the radiator fan
may remain on or turn itself back on for up to
10 minutes, even if the ignition is switched
off. This may occur for the following reasons:
- Residual heat has raised the coolant
tem­

perature.
- Direct sunlight has additionally heated up
the engine compartment while the engine is

warm.

- Applies to vehicles with diesel particulate
filter: The emission control system is hot
because of the regeneration process, even
though the engine has
not
yet reached oper­
ating temperature.

® For the sake of the environment
Do not warm up the engine by running it with
the car stationary. You should drive off imme­
diately whenever possible. This will help avoid
unnecessary exhaust emissions.
© Note
- Any noises which may be heard when the
engine is started are quite normal and no
cause for concern.
- If
you
leave your vehicle with the ignition
switched on, it will be switched off auto­
matically after
a
while. Please note that
electrical equipment such as the exterior
lighting will also be switched off.

Steering
lock15

The steering will be locked if
you
switch off the
engine with the ISTART ENGINE STOP| button,
move the selector lever to position P (on vehicles
with automatic gearbox*) and open the driver's
door. The steering lock acts as a theft deterrent.
Emergency Off function
If necessary in an emergency, the engine can be
switched off while the vehicle is still moving at
speeds of 7 km/h and above. To switch off the
engine, press the ISTART ENGINE STOP| button
twice in quick succession or hold it in for longer
than two seconds.
A WARNING
- Never switch off the engine until the vehicle
is stationary. Otherwise you may not have
the full benefit of the brake servo and pow­
er steering. You may need more strength to
steer and brake the vehicle than you nor­
mally would. This would mean a greater risk
of accidents and serious injury, because you
cannot steer and brake in the normal
man­

ner.
- Always take the key with you when you Leave
the vehicle. Otherwise the engine can be
started or power-operated equipment such
as the electric windows can be used. This
could result in serious injury.
- When parking, always move the selector
lever to position
P
to prevent the vehicle
from rolling back accidentally.
If the engine has been working hard for
a
long

time,
there is a risk of heat building up in the
engine compartment after the engine has
been switched off; this could cause engine
damage. For this reason, you should leave the
engine idling for about 2 minutes before
switching it off.

Parking aids
Parking aids
General notes
Applies to: vehicles with rear parking aid/parking system
plus/reversing camera/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicLe.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car

cépage
135.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicLe

^page
135.
The reversing camera uses the infotainment sys­
tem display to show a picture of the area behind
the vehicle captured by the camera. This picture
helps you to park the vehicle parallel or perpen­
dicular to the roadside. In addition, you are assis­
ted by the functions of the parking system plus

^>page
137.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicLe into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb
^>page
139. It
also includes the functions of the parking system
plus
^page
135 and additionally monitors the
area at the side of the vehicle
(f) ^page

Fig. 124.

A
WARNING
- Always watch the road and the area sur­
rounding the vehicLe. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­

vres.

- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system - risk of accident!
- The sensors and cameras have bLind spots in
which neither people nor objects are regis­

tered.
It is particularly important to ensure
that there are no small children or animals
near the vehicLe - risk of accident!
- Always keep a close watch on the area
around the vehicLe and make full use of the
rear-view mirrors.
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.

(T)
CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­

tures,
such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note
that
you will no longer
be warned about these obstacles.
- Remember to maintain sufficient clearance
from the kerb to avoid damaging the wheel

rims.

(T)
Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
-To familiarise yourself with the system, we
recommend
that
you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can change the display and adjust the
volume and pitch of the beeps

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­

ing.
This allows unburnt fuel to enter the exhaust

system,
which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehi­

cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!

Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area
oA-

A WARNING
- Switch off the engine.
-Switch off the ignition.

-Applythe
parking brake.
- On vehicles with manual gearbox place the
gear lever in neutral, on vehicles with auto­
matic gearbox move the selector lever to
position P.
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- Wait for the engine to cool down.
- Keep children away from engine compart­
ment.
- Never spill fluids on a hot engine. These
flu­

ids can cause a fire (e.g. radiator
anti­

freeze).
- Take care not to cause short circuits in the
electrical system.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off - risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive

belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart­
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi­
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other

fluids,
have your vehicle inspected in the
workshop.

- Never use washer fluid which contains paint
thinners or solvents as it can damage the
paintwork.
Service interval display

The
service interval display detects when the
next
service
is due
for
your vehicle.
There are two service interval dispLay levels:
- Inspection or oil change reminder: After a cer­
tain mileage, a service reminder will appear in
the instrument cluster dispLay each time the ig­
nition is switched on/off. The distance or time
remaining will be shown briefly.
- Inspection or oil change due: When your
vehi­

cle is due for an inspection, oil change or
both,

the corresponding reminder Inspection
due!,

Oil change due! or Oil change and inspection

due!
will appear briefly after you switch the ig­
nition on/off.

Service intervals.

Applies
to: vehicles with flexible oil change service
You cannot check the service interval on a new
vehicle until it has been driven for about 500 km.
Qualified workshops reset the service interval af­
ter the oil is changed. The distance to the next oil
change is initially displayed based on the driving
profile prior to the oil change. Your own personal
driving profile is used subsequently to calculate
the remaining distance. Frequent cold starts or
short trips place extra demands on the engine oil
with the result that the oil has to be changed
more often.
Resetting the display
Your qualified workshop resets the service inter­
val display after each service.
It is very important that you reset the oil change
dispLay if
you
change the oil yourself. The
next
oil
change will be due after
a
fixed service interval.

(J) CAUTION

- Do not reset the oil change interval display
unless you have changed the oil.
- Keeping to the correct service intervals is
crucial for the operation, service life and re­
sidual value of the vehicle (and especially
for the life of the engine). Services must al­
ways be carried out promptly, even if the
mileage is Low.
