Coolant temperature gauge
The coolant temperature gauger=> page 10,
Fig. 3@ 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
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 on the infotainment display, the coolant tem­
perature is too high r=> page 14.
10 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
assista nee.
i 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.
Fuel gauge
The gauge @only works when the ignition is
switched on. If there is less than 7 litres of fuel in
the tank, a red LED will light up and the indicator
lamp I]] will appear r=> page 18. The LED will
flash in red if the fuel level is very low.

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 °( (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 sufficient­
ly (this does not apply to the defrost setting).
� Adjusting the blower speed
The rotary control @ can be used to adjust the
blower speed in small steps. You should leave
the blower on at a low setting to prevent the win­
dows from misting up and to ensure that the ve­
hicle interior is constantly ventilated. You can ad­
just the blower speed manually. Press the !AUTO!
button for automatic control of the blower
speed.

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.
{(D 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.

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 will
otherwise start moving immediately 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.

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 by a warning lamp
• ¢page 14. However, we recommend that it
should be checked occasionally.
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
G13 TL 774
J
G12++ TL 774 G
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

Downloaded from www.Manualslib.com manuals search engine Checking
and topping up fluids
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
system -risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­
tance.

brake fluid level
� Read off the brake fluid level on the brake fluid
reservoir ¢page 246, Fig. 214. The brake fluid
level must be between the MIN and MAX marks
¢_A.
The brake fluid level is also automatically moni­
tored.
Having brake fluid changed
Have the brake fluid changed regularly by a quali­
fied workshop.
A WARNING
- If the brake fluid level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired -risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!
CD CAUTION
- If the brake fluid level is above the MAX
mark, brake fluid may escape via the cap on
the reservoir in certain circumstances and
cause damage to the vehicle.
- Brake fluid must not be allowed to come in­
to contact with the vehicle's body, other­
wise it will attack the paintwork.
Battery General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by a qualified
workshop ¢ ,& .
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
