The essentials
● Ret
urn al
l tools to their proper storing loca-
tion.
● If the replaced wheel does not fit in the
spar
e wheel housing, store it safely in the
luggage compartment ›››
 page 148.
● Check the tyre pressure of the newly moun-
ted tyr
e as soon as possible.
● In vehicles fitted with a tyre pressure indi-
cator
, adjust the pressure and store the read-
ing in the radio/Easy Connect system*
›››  page 259.
● Have the tightening torque of the wheel
bolts c
hecked as soon as possible with a tor-
que wrench (it should be 120 Nm). Mean-
while, drive carefully.
● Have the flat tyre replaced as quickly as
poss
ible.
Snow chains Use Snow chains should only be used on the
fr
on
t

wheels.
Check that they are correctly seated after
driving for a few yards; correct the position if
necessary, in accordance with the manufac-
turer's fitting instructions. Keep your speed
below 50 km/h. If there is a danger of being trapped despite
havin

g mounted the chains, it is best to disa-
ble the driving wheels (ASR) in the ESC
›››  page 180, Switching on/off the ESC
and ASR.
Snow chains will improve braking ability as
well as traction in winter conditions.
For technical reasons snow chains may only
be used with the following wheel rim/tyre
combination.
195/65 R15Chains with links of maximum 15 mm
205/55 R16Chains with links of maximum 15 mm
225/45 R17Chains with links of maximum 9 mm
225/40 R18Chains with links of maximum 9 mm Remove wheel covers and any integral trim
rin

or

e fitting snow chains.
Remove the chains when roads are free of
snow. Driving characteristics worsen, and the
wheels become damaged quickly and may
even be rendered unusable. Emergency towing of the vehi-

Operation
A cold engine consumes a disproportionate
amou nt
of
fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 256 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
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.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. This will save, at a speed
of 100-120 km/h (60-75 mph), 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off any unneeded electrical devices. Devices that
use a lot of
electricity includes the blower at
a high setting, the rear window heating or
the seat heating*. Driver assistance systems
Br ak
in
g and stability systems
Electronic Stability Control (ESC) The ESC helps to improve safety. It reduces
the tendency
t

o skid and improves the stabil-
ity and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehi-
cle by braking individual wheels or by reduc-
ing the engine torque. The warning lamp will
flash on the instrument panel when the ESC
is intervening .
ESC includes the Anti-lock brake system
(ABS), the brake assist system, the traction
control system (ASR), electronic differential
lock (EDL), electronic self-locking*, selective
torque control* and tractor-trailer sway miti-
gation*. ESC also helps stabilise the vehicle
by changing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer
the vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake ped-
al pulsate while the ABS is working.
178

Driver assistance systems
Brake assist system
The br ak
e a
ssist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. This helps the
car to start moving, accelerate or climb a gra-
dient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch
on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: Tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto- matically brake the towing vehicle within the
limits of the sy
stem and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” 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 in
Sport mode or disconnected. Multi-collision brake
In an accident, the mu
lti-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the
vehicle, as long as the accident has not dam-
aged the ESC, the brake hydraulics or the on-
board network.
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, EDL, el ectr

onic self-
locking differential or selective torque control
systems cannot exceed the limits imposed by
the laws of physics. Always bear this in mind, » 179

Safety

Operation
especially on wet or slippery roads. If you no-
tice the sy
s
tems cutting in, you should re-
duce your speed immediately to suit the road
and traffic conditions. Do not be encouraged
to take risks by the presence of more safety
systems. If you do, an accident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDL, electronic
self-locking and selective torque control sys-
tems cannot prevent accidents: risk of acci-
dents!
● Accelerate with caution on slippery surfa-
ces
(for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i

ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can mak
e noises when they intervene.
● If the warning lamp  lights up
, or  alter-
natively, there could be a fault ››› page 108. Switching on/off the ESC and ASR

eering.
Electro-mechanical power steering adapts
electronically to the speed of the car, torque
and turning angle.
If the power steering should fail at any time
or the engine is switched off (for instance
when being towed), the car can still be
steered. However, more effort than normal
will be required to turn the steering wheel.
