Driving
●
Never use the handbrake to brake the vehi-
cle except in an emergency. The braking dis-
tance is considerably longer, because braking
is only applied to the rear wheels. Always use
the foot brake.
● Never drive with the handbrake gently ap-
plied. This can overheat the brake, affecting
the brakes system. This also causes prema-
ture wear on the rear brake pads.
● Never accelerate from the engine compart-
ment with the engine running and a gear en-
gaged. The vehicle could move, even if the
handbrake is applied. Note
If the vehicle moves at a speed superior to
6 km/h (4 mph) with the handbrake applied,
an audible warning is sounded. Parking
When parking your vehicle, all legal require-
ments should be observed.
To park the vehicle
Complete operations only in the sequence
given.
● Park the vehicle on a suitable surface ››› .
● Press and hold the brake pedal until the ve-
hicle comes to a standstill.
● Apply the handbrake firmly ››› page 90. ●
For an automatic gearbox, move the selec-
tor lever to position P
.
● Sw
itch off the engine and release the brake
pedal.
● Remove the key from the ignition.
● If necessary, turn the steering wheel slight-
ly to lock the steering.
● With a manual gearbox, engage 1st gear on
flat ground and slopes, or even reverse gear
on hills, and release the clutch pedal.
● Ensure that all passengers leave the vehi-
cle, especially children.
● When leaving the vehicle, take all keys with
you.
● Lock the vehicle.
Additional information for steep slopes and
hills
Before switching off the engine, rotate the
steering wheel so that if the vehicle should
move, it will be held by the kerb.
● On slopes, turn the front wheels so that
they are against the edge of the kerb.
● Uphill, turn the wheels towards the centre
of the road. WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire and considerable damage. ●
Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as wood,
leaves,dried grass, or spilled fuel). CAUTION
● Special care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam-
age the bumper or other parts of the vehicle
during manoeuvres. To avoid damage, stop
before the wheels touch the barrier or kerb.
● Special attention is required when driving
through entrances, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as
you drive over these objects. Information about the brakes
For the first 200 to 300 km, the new brake
pads
have not yet reached their maximum
br ak
ing capacity, and need to be “run in”
first ››› . The slightly reduced braking effect
can be compensated for by increasing pres-
sure on the brake pedal. While running in,
the f u
ll braking distance or emergency brak-
ing distance is larger then when the brake
pads have been run in. While running in,
avoid full power braking or situations requir-
ing braking performance. For example, in
heavy traffic. »

Safety
Operation
the driver control the vehicle due to the loss
of adherence with the road surface prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC* will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations
and uses the movements of the steering
made by the driver to maintain the vehicle
moving in the desired direction. If the vehicle
is driven at such a speed that it will leave the
road before ESC* can intervene then the sys-
tem cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock brake system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remove your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
braking force!
● Maintain vehicle direction when braking
fully.
● When the brake pedal is released or when
the brake force is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
e xpect
the ABS to reduce the braking dis-
tance under
any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively. ¡Do not lift your foot off the brake pedal!
When the br
ake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control system (ASR) or Traction
Control (TC)
In the event of wheelspin, the traction control
system ASR or TC reduces the engine torque
to match the amount of grip available. The
ASR or TC makes some situations easier, for
example, when starting, accelerating or go-
ing uphill, even in unfavourable road condi-
tions.
Electronic differential lock system (EDL)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel
and directs the power to the other one. To
prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or wet
ground can result in loss of vehicle control 1)
Depending on the version.

Operation
The City Safety Assist function is limited by
the laws of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
For example, the following driving situations
require special attention:
Driving through a bend
When entering or leaving a “long” bend, the
vehicle may decelerate when the radar sen-
sor detects a vehicle travelling in the adjoin-
ing lane ››› Fig. 91
A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The radar sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 91 B. This applies especially
to n
arrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system ›››
Fig. 92. To inter-
rupt dec
eleration you can accelerate, turn the
steering wheel or press the clutch. Malfunction in the radar sensor
If the radar sensor operation is impaired, for
example due to heavy rain, mist, snow or dirt,
the City Safety Assist system function is tem-
porarily switched off. On the instrument pan-
el display the control lamp
flashes.
When the fau
lt in the radar sensor has been
rectified, the City Safety Assist system func-
tion automatically becomes available. The
control lamp
switches off.
The following conditions could prevent the
City Safety Assist system from functioning:
● Tight bends.
● Accelerator pressed all the way down to the
floor.
● If the City Safety Assist system is switched
off or there is a fault ››› page 111.
● If the radar sensor is dirty, covered or over-
heated ››› page 112.
● In the event
of snow, heavy rain or dense
fog.
● If there are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● Very dirty vehicles with a low degree of re-
flection.
● Presence of thick dust. Hill driving assistant*
Operation 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 positions S
, D
or R in vehi-
cles with an automatic gearbox.
This system is also active when reversing up-
hill.

Operation
Vehicles with an automatic gearbox
● When the vehicle is at a standstill, depress
the brake or keep it pressed down. The en-
gine switches off.
● The engine will start again as soon as you
release the brake pedal.
● With the selector lever set to position N,
the en gine w
ill not start until a range of gears
is selected or the accelerator pedal is de-
pressed.
Important conditions for the engine to stop
automatically
● The driver's seat belt must be fastened.
● The driver door must be closed.
● The bonnet must be closed.
● The engine must have reached a minimum
temperature.
● The vehicle must have moved since the last
time the engine was stopped.
● The vehicle's battery must be sufficiently
charged.
● The battery temperature must not be too
low or too high.
● The vehicle must not be on a very steep
slope. Conditions for the engine to restart
automatically
The engine can be automatically restarted in
the following cases:
●
If the vehicle starts to moves.
● If the battery voltage drops.
Conditions requiring engine start-up using
the key
The engine has to be manually started in the
following cases:
● If the driver unbuckles his/her seat belt.
● If the driver door is opened.
● If the bonnet is opened.
Switching the Start-Stop system on and off
● Press the button situated in the centre
console ››› Fig. 93
.
● The button will light up when the Start-Stop
system is switched off.
The engine will start immediately if the vehi-
cle is in Stop mode when the system is
switched off by hand. WARNING
The smart technology included in the hill
hold cannot change the laws of physics. Do
not let the extra convenience afforded by the hill hold tempt you into taking any risks
when driving.
●
Any accidental movement of the vehicle
could result in serious injury.
● The hill hold is not a replacement for driver
awareness.
● Adjust your speed and driving style to visi-
bility, weather, road and traffic conditions.
● The hill hold cannot always keep the vehi-
cle at a standstill on a slope or brake suffi-
ciently when travelling downhill (e.g. on slip-
pery or frozen surfaces). WARNING
The brake servo and the electromechanical
steering do not work when the engine is
switched off.
● The vehicle must never be allowed to move
with the engine switched off.
● Disconnect the Start-Stop system before
working in the engine compartment. CAUTION
The vehicle's battery could be damaged if the
vehicle is used for long periods at very high
outside temperatures. Note
In some cases, it may be necessary to start
the engine by hand using the key. Refer to 116

–The vehicle is running in natural gas operating mode.–
a)
This only applies to vehicles with the fuel gauge on the dash panel display.
Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
In natural gas engines
The warning lamp lights up when both fuel
type
s (petrol and natural gas) have reached
reserve level.
The warning lamp lights up when the vehi-
cl
e is running in natural gas operating mode.
The 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 just after refuelling, the gas level
indicator does 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 pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note
The arrow next to the fuel pump symbol on

Advice
Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetrated through the tyre wall!
● You should obtain professional assistance
immediately.
Wear of tyres
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving style : Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out : The wheels on new vehicles
ar e b
alanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment checked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one side while driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
observing the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitoring system*
Fig. 117
Centre console: tyre monitor system
button The tyre control lamp compares wheel revolu-
tions and with it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp
lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 117 button must
be k ept
pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.

Emergencies
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 143.
● The b att
ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow starting
Introduction When towing or tow starting, respect the le-
gal requirements.
For technical reasons, it is not possible to
tow a vehicle if the battery is flat. WARNING
A vehicle with a flat battery should never be
towed.
● Never remove the key from the ignition
lock. Otherwise, the steering wheel lock
could suddenly lock. The vehicle would not
be controlled and a serious accident could
ensue. WARNING
When towing the vehicle, the handling and
braking efficiency change considerably.
Please observe the following instructions to
minimise the risk of serious accidents and in-
jury:
● As the driver of the vehicle being towed:
– The brake must be depressed must hard-
er as the brake servo does not operate.
Always remain aware to avoid collision
with the towing vehicle.
– More strength is required at the steering
wheel as the power steering does not op-
erate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and
brake gently.
