Driving
●
The brak in
g capability of your vehicle is
limited by the tyres' grip. It is therefore no
different from a car without four-wheel drive.
So do not be tempted to drive too fast on firm
or slippery roads just because the vehicle
still has good acceleration in these condi-
tions. Risk of accident!
● On wet roads bear in mind that the front
wheels m
ay start to “aquaplane” and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as occurs with a front-wheel drive car.
For this reason you should always choose a
driving speed suitable for the road condi-
tions. Risk of accident! 207

ssions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops or is
stopping; for example when stopping at traf-
fic lights. The ignition remains switched on
during the stopping phase. The engine auto-
matically switches back on when required. In
this situation, the light of the START ENGINE STOP button stays on
1)
.
As soon a
s
the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Further information about the Start-Stop sys-
tem can be found in the Easy Connect sys-
tem: by pressing the button in the Vehi-
cle status menu.
B a
s
ic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fas-
tened. ●
The bonnet mus
t be closed.
● The engine must have reached a minimum
servic
e temperature.
● The reverse gear must not be engaged.
● The vehicle must not be on a very steep
slope. WARNING
● Never sw it
ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop sys
tem is switched off when working in
the engine compartment ››› page 210. CAUTION
The Start-Stop system must always be
swit c
hed off when driving through flooded
areas ››› page 210. Stopping/Starting the engine
Vehicles with a manual gearbox
– Before stopping the vehicle or when it is
stop
ped, put it into neutral and release the
clutch pedal. The engine will switch off. The
warning lamp will appear on the instru-
ment panel display. The engine may stop
before the vehicle comes to a halt in the
deceleration phase (at 7 km/h).
– When the clutch pedal is pressed the en-
gine wil
l start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox – Use the foot brake to bring the vehicle to a
stop and k
eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp will appear in the
display. The engine may stop before the ve-
hicle comes to a halt in the deceleration
phase (at 7 km/h or 2 km/h, depending on
the vehicle’s gearbox).
– When you take your foot off the brake pedal
the engine wi
ll start up again. The warning
lamp will switch off. In vehicles with the Au-
to Hold* system, when the system is active,
the engine will not start if you remove your
foot from the brake pedal. The car starts
when you press the accelerator pedal. 1)
Only in vehicles with Keyless Access.

Additional information related to the auto-
m atic
g
earbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.
Additional information about vehicles with
Adaptive Cruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again. Note
● In v ehic
les with an automatic gearbox, you
can control whether the engine should switch
off or not by reducing or increasing the brake
force applied. While the vehicle remains stop-
ped, the engine will not stop if the brake ped-
al is slightly pressed, in traffic jams with fre-
quent stopping and starting for example. As soon as strong pressure is applied to the
brak
e ped
al, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes
The system can interrupt the Start-Stop mode
fr
equently
f
or different reasons.
The engine does not switch off
Before the stopping phase, the system veri-
fies whether certain conditions are met. The
engine does not switch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required t
emperature for the Start-Stop
mode.
● The interior temperature selected for the air
conditioner ha
s not yet been reached.
● The interior temperature is very high/low.
● Defrost function button activated
›› ›
page 51.
● The parking aid* is switched on. ●
The batt er
y is very low.
● The steering wheel is overly turned or is be-
ing turned.
● If
there is a danger of misting.
● After engaging reverse gear.
● In case of a very steep gradient.
The indication
is shown on the instrument
panel display, and in addition, the driver in-
formation system* shows, .
The engine starts by itself
During a stopping phase the normal Start-
Stop mode can be interrupted in the follow-
ing situations: The engine restarts by itself
without involvement from the driver.
● The interior temperature differs from the
value select
ed on the air conditioner.
● Defrost function button activated
›››
page 51.
● The brake has been pressed several times
consec
utively.
● The battery is too low.
● High power consumption. Note
In vehicles with an automatic gearbox, if the
select or l
ever is placed in position D, N or S
after engaging reverse gear, the vehicle must
be driven at a speed faster than 10 km/h (6 » 209

Hill Descent Control (HDC) De s
cription and operation 3 V
alid for vehicles: 4Drive
Hi
ll Descent Control limits the speed on steep
descents by automatically braking all four
wheels, both when moving forward and in re-
verse. As the anti-lock brake system remains
active, it prevents the wheels from locking. In
vehicles with manual transmission, the Hill
Descent Control adapts the theoretical speed
without slowing the engine below its idling
speed. After starting the descent of a slope below
30 km/h (18 mph), speed i
s
limited to a min-
imum of 2 km/h (1 mph) and a maximum of
30 km/h (18 mph). When appropriate, the
driver may increase or decrease the speed
within the limit by pressing the accelerator or
the brake. At this point the function is inter-
rupted and, if necessary, it is then reactiva-
ted.
Even so, it is imperative that the surface
guarantees sufficient adhesion. For this rea-
son, the Hill Descent Control will not fulfil its
function when, for example, descending a
slope with a frozen or slippery surface.
Hill Descent Control is available when the
dash panel display shows the message .
Hill Descent Control automatically intervenes
if the following conditions are met:
● The vehicle engine is running.
● The Offroad driving profile has been selec-
ted ›
›› page 242. Driving at a speed below 30
km/h (18 mph) (the message is shown on
the dash panel display).
● The slope of the descent is at least 10%
when driving f
orward and 9% when driving in
reverse.
● The brake and the accelerator are not
pres
sed.
Hill Descent Control is deactivated on press-
ing the brake and the accelerator or if the
slope is below 5%. The function may be

remains on when the Auto Hold function is
connected.
Once connected, the Auto Hold function as-
sists the driver in keeping the vehicle station-
ary at repeated intervals or for a certain peri-
od of time with the engine running, for exam-
ple, when going up a slope, when stopped at
traffic lights or in heavy traffic with intermit-
tent stops. When connected, the Auto Hold function au-
tomatic
ally prevents the vehicle from rolling
when stationary without pressing the brake
pedal.
After detecting that the vehicle is stationary
and the brake pedal has been released, the
Auto Hold function holds the vehicle. The
driver can lift their foot off the brake pedal.
When the driver touches the accelerator ped-
al or accelerates slightly to continue driving,
the Auto Hold function releases the brake.
The vehicle moves according to the slope of
the road.
If the vehicle is stationary and one of the con-
ditions required by the Auto Hold function is
impaired, it disconnects itself and the but-
ton's control light goes out ››› Fig. 185. The
electronic parking brake connects automati-
cally, if necessary, to park the vehicle safe-
ly ››› .

The Auto Ho l
d function cannot always keep
the vehicle stationary uphill or downhill or
stop it sufficiently, for example, on slippery

Use of the cruise control could cause acci-
dents and sev
ere injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the dis
tance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpav
ed roads.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
contro
l system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the pr
evailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a c
onstant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. WARNING
