Operation
Engine cold
If only the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard.
Normal temperature
If in normal operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 203. CAUTION
● To ensure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
››› page 77 as a guide. ●
Additional lights and other accessories in
front of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
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 re-
duce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Gas

››› Fig. 82 only work when
the ignition i s
switched on. When the display
reaches the reserve mark, the lower diode
lights up in red and the control lamp  ap-
pears ››› page 66. When the fuel level is very
low

, the lower diode flashes in red. The yellow control lamp 
lights up when the
reserve level has been reached.
The green warning lamp 
lights up when the
vehicle is running in natural gas operating
mode.
The green warning lamp 
switches off when
the natural gas is exhausted. The engine
changes to operate with petrol.
Problem:
If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

Driver assistance systems
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● Apply the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the engine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subjected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. CAUTION
● Never let the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is advisable to reduce speed and select a
lower gear. This makes use of engine braking and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously.
Note
● If the brake servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories such as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S,
D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If you do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or use the hand brake immediately.
● When following a line of traffic uphill, if you
want to prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. » 147

W ork
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). Al-
ways observe the warnings listed below and
follow all general safety precautions. The en-
gine compartment of the vehicle is a poten-
tially hazardous area
››› . WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place
the lever in neutral; if it has an automatic
gearbox, place the selector lever in position
P.
● Wait for the engine to cool down.
● Keep children away from the engine com-
partment.
● Never spill liquids used for vehicle opera-
tion on the engine compartment, as these
may catch fire (e.g. the antifreeze in coolant). 198

Checking and refilling levels
●
Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
● If working inside the engine compartment,
remember that, even when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury.
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion 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.
● If it is necessary to work in the engine com-
partment while the engine is running, the ro-
tating components (for example, poly-V belt,
alternator, radiator fan) and the high voltage
ignition system are an additional hazard.
● Observe the following additional warnings
if work on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening, oth-
erwise this can 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 in the area where it was parked, have
your vehicle inspected at the workshop. Note
On right-hand drive vehicles* some of the
containers/reservoirs mentioned below are
located on the other side of the engine com-
partment. Opening the bonnet
Read the additional information carefully
›››  page 10
The bonnet is released from inside the vehi-
cle.
Check that the windscreen wiper arms are
not unfolded. Otherwise the paint may be
damaged.
The bonnet can only be unlocked when the
driver door is open. WARNING
Never open the bonnet if you see steam or
drips of coolant being released from the en-
gine compartment. Failure to comply could
result in burns. Wait until no steam or coolant
can be seen before opening the bonnet. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay before pressing it
back into its support.
– Carefully close the bonnet.
– Press the bonnet down until it locks into
place.
– Make sure that the bonnet catches onto its
clasp. Do not press down too hard › › › .
WARNING
● For safety reasons the bonnet must always
be completely closed when the vehicle is
moving. Therefore, after closing the bonnet,
always check that the locking element is
properly engaged. This is the case if the bon-
net is flush with the adjacent body panels.
● Should you notice that the bonnet is not
safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet. Failure to follow this instruction
could result in an accident. 199
