Fig. 3 CD only works when the ignition is switched
on. In order to avoid possible damage to the en­
gine, please read the following notes for the dif­
ferent temperature ranges.
Engine cold
If the LEDs are still in the left-hand range of the
display, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine
loads.
Normal temperature
In normal operation the LEDs will settle some­
where in the centre of the dis play once the en­
gine has reached operating temperature. The
LEDs may also extend further into the right-hand
range of the display when the engine is working
8 hard
at high outside temperatures. This is no
cause for concern provided the warning lamp.

the red LEDs reach the right-hand part of the dis­
play and the warning lamp.
appears in the dis­
play, the coolant temperature is too high
¢page 12.
CD CAUTION
- 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
Diesel 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.

the coolant level¢ page 224.
- If the coolant level is too low, add more coolant
¢ page 225. Do not drive on until the warning
lamp has gone out.
- If the coolant level is correct, the overheating
may be caused by a malfunction of the radiator
fan. Do not drive on. Obtain professional assis­
tance.
• Coolant temperature: too high. Let engine
run with vehicle stationary
Let the engine cool down by running it at idling
speed for a few minutes.
A WARNING
- Never open the bonnet if you can see or hear
steam or coolant escaping from the engine
compartment; there is a risk of being scal­
ded. Wait until you can no longer see or
hear escaping steam or coolant.
- The engine compartment of any motor vehi­
cle is a dangerous place. Before carrying out
any work in the engine compartment,
switch off the engine and allow it to cool
down. Please observe the important safety
warnings ¢ page 220, Working on compo­
nents in the engine compartment.

for automatic air conditioner
Applies to vehicles: with automatic air conditioner
Fig. 65 Automatic air conditioner: Controls
The rotary controls, the buttons in the rotary con­
trols and the switches are used to control the
functions. The functions can be switched on and
off by pressing the buttons. The LED in the corre­
sponding button lights up when the function is
switched on.
We recommend pressing the !AUTO! button and
setting the temperature to 22 °C (72 °F). The air
conditioner is fully automatic, and will maintain
the desired temperature at a constant level. The
temperature of the air supplied to the interior,
the blower speed and the air distribution are
regulated automatically. When the heater is on,
the blower normally only switches to a higher
speed once the coolant has warmed up suff icient­
ly (this does not apply to the defrost setting).
Key-coded settings: The automatic air condition­
er settings are automatically stored and assigned
to the remote control key which is being used.

WARNING
- Never run the engine in confined spaces.
The exhaust gases are toxic -risk of poison­
ing!
- Never switch off the engine until the vehicle
is stationary.
- The brake servo and the power steering sys­
tem work only when the engine is running.
You need more strength to steer and brake
the vehicle when the engine is switched off.
This would mean a greater risk of accidents
and serious injury, because you cannot steer
and brake in the normal manner.
Avoid high engine speeds, full throttle and ex­
treme load conditions until the engine has
reached its normal operating temperature;
otherwise this can damage the engine.
{:!)) Note
- When starting from cold the engine may be
a little noisy for the first few seconds until
oil pressure has built up in the hydraulic
tappets. This is quite normal and no cause
for concern.
- If you leave the 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.

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 power
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.
CD CAUTION
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.
(1'> Note
After the engine is stopped the radiator fan
may run on for up to 10 minutes, even if the
ignition is switched off. The fan may also start
running again after some time if the coolant
temperature rises due to a build-up of heat,

.... -
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, especially when working
on the battery.
- 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.
- 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.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle
could otherwise start moving immediately
and possibly cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Always disconnect the battery.
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
CD 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. Checking
and topping up fluids
® 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.

Depending on how you drive and the conditions
in which the car is used, oil consumption can be
up to 0.5 Ltr./1000 km. Oil consumption is Likely
to be higher for the first 5000 km. For this rea­
son the engine oil Level must be checked at regu­
lar intervals, preferably when filling the tank and
before a journey.

_& WARNING
- Ensure that no oil comes into contact with
hot engine components when topping up:
this could cause a fire.
- Wash your skin thoroughly if it comes into
contact with engine oil.
CD CAUTION
- The oil Level must never be above area 0, as
this may result in damage to the catalytic
converter or to the engine. Contact a qua Li-
224 fied
workshop to extract the engine oil if
necessary
- No additives should be used with engine oil.
Any damage caused by the use of such addi­
tives would not be covered by the factory
warranty.
@ For the sake of the environment
- Never pour oil down drains or into the
ground.
- Always observe statutory requirements
when disposing of empty oil canisters.
Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant Level is monitored via a warning Lamp
on the infotainment display ¢page 12. However,
we re com mend that it shou Ld be checked occa­
sionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter .
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.
Coolant additive Specification

ble: G12+
The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too Low, the coolant
can freeze and cause engine damage.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.
Topping up coolant
Fig. 214 Engine compartment: Cap of coolant expansion
tank
Checking coolant level
.. Park
your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan­
sion tank ¢ page 222, Fig. 211. When the en­
gine is cold, the coolant level should be be­
tween the marks. When the engine is warm, it
may be slightly above the top mark. Checking
and topping up fluids
Topping up coolant
Impor tant: The coolant expansion tank must not
be empty ¢(D.
.. Wait for the engine to cool down.
.. Cover the cap on the expansion tank with a
cloth, and carefully unscrew the cap anti-clock­
wise ¢ .&_ .
.. Add coolant in the correct concentration
¢ page 224 up to the top mark.
.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- 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!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys­
tem -risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .
