Driving
grip on the front axle, resulting in understeer
or “l en
g
thening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected or the ESC is
in Sport mode.
Brake servo The brake servo increases the pressure you
ap
p
ly

to the brake pedal. It works only when
the engine is running .
If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
ext ern

al factors.
● Never let the vehicle coast with the engine
switc
hed off. Failure to follow this instruction
could result in an accident. The braking dis- tance is increased considerably when the
brak
e ser

vo is not active.
● If the brake servo is not working, for exam-
ple when the
vehicle is being towed, you will
have to press the brake pedal considerably
harder than normal. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hi l

l 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, ●
bes ide

s 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 y

ou 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 u
se the hand brake immediately.
● When following a line of traffic uphill, if you
want t
o prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. Note
The Official Service or a specialist workshop
can t el

l you if your vehicle is equipped with
this system. 157

 page 37
Certain versions of the model may include a
6-speed manual gearbox, and its diagram is
shown on the gearbox lever.
The reverse gear can only be engaged when
the car is stationary. When the engine is run-
ning and before engaging this gear, wait
about 6 seconds with the clutch pressed
down thoroughly in order to protect the gear-
box.
The reverse lights switch on when the reverse
gear is selected and the ignition is on. WARNING
● When the engine i s

running, the vehicle
will start to move as soon as a gear is engag-
ed and the clutch released.
● Never select the reverse gear when the ve-
hicle i
s in motion. Risk of accident. Note
● Do not r e

st your hand on the gear lever
while driving. The pressure of your hand
could cause premature wear on the selector
forks in the gearbox. ●
When ch an

ging gear, you should always
depress the clutch fully to avoid unnecessary
wear and damage.
● Do not “slip” the clutch to hold the vehicle
on a hill
. This causes premature wear and
damage to the clutch.
● Do not leave your foot on the clutch pedal;
although the pre
ssure may seem insignifi-
cant, it can cause the premature wear of the
clutch plate. Use the foot rest when you do
not need to change gear. Gear-change indicator

Operation
the engine. Avoid running the engine at high
s peed.
P eriodic
maintenance
Periodic maintenance work guarantees that,
before beginning a journey, you will not con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of
polluting exhaust gases, the engine and the
exhaust gas filtration systems should reach
the optimum operating temperature.
With the engine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres (2.5 miles). This is why we recom-
mend avoiding short trips whenever possi-
ble.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi/100 kPa) too
low, fuel consumption can increase by as much as 5%. Due to the greater rolling resist-
ance, under
-inflation also increases tyre wear
wear and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
A roof rack is often left in place for the sake
of convenience, even when it is no longer
needed. At a speed of 100 km/h (62 mph)
and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
blower at high speeds, the rear window heat-
ing or the seat heaters*. Note
● If y

our vehicle has Start-Stop, it is not rec-
ommended that you switch this function off.
● It is recommended that you close
the win-
dows when driving at more than 60 km/h
(37 mph).
● Do not drive with your foot resting on the
clutc
h pedal,, as the pressure can make the
plate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the car on a hill with the clutch,
use the foot
brake or hand brake, using the
latter to start. The fuel consumption will be
lower and you will prevent the clutch plate
from being damaged.
● On descents, use the engine brake, chang-
ing to the g
ear that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Engine management and ex-

WARNING
Never allow the vehicle to move with the en-
gine off f or an
y reason. You could lose control
of your vehicle. This could cause an accident
and serious injury.
● The brake servo does not work with the en-
gine off. Y
ou need more force to stop the vehi-
cle.
● Power steering does not work when the en-
gine is not
running. That is why it is much
more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving
through wat
er (fording streams, etc.). Note
● For v

ehicles with the Start-Stop function
and a manual gearbox, when the engine is
started, the clutch must be pressed.
● When the conditions for the Start-Stop
function ar
e not fulfilled, the instrument pan-
el displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than
270°, it wi
ll not be possible to start the vehi-
cle again. To start the vehicle, straighten the
steering wheel so that it is turned less than
270°.

OFF or turn the ignition off
if

the vehicle is
stationary. WARNING
It could be dangerous to use the cruise con-

stant speed.
● Do not use the cruise control system when
driving in den
se traffic, on roads with lots of
bends or on roads with poor conditions (with ice, slippery surfaces, loose grit or gravel), as
this
c

ould cause an accident.
● Always switch the cruise control system off
after u

● It is dangerous to use a set speed which is
too high for the c
urrent road, traffic or weath-

The cruise control cannot maintain a constant
s peed when de s

cending downhill. It will in-

Setting a higher speed
● Press the upper part of the rocker switch

will automatically restore the set speed. This
will not be the case, however, if the vehicle
speed exceeds the stored speed by more
than 10 km/h (6 mph) for longer than 5 mi-
