Driving SteeringIntroduction The power steering is not hydraulic but electromechanical. The advantage
of thi
s
steering system is that it disposes of hydraulic tubes, hydraulic oil,
the pump, filter and other components. The electromechanical system
saves fuel. While a hydraulic system requires oil pressure to be maintained,
electromechanical steering only requires energy when the steering wheel is
turned.
With the power steering system, the assisted steering function automatical-
ly adjusts according to the vehicle speed, the steering torque and the wheel
turning angle. The power steering only works when the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 170
● V
ehicle battery ⇒ page 288
● T
ow-starting and towing away ⇒ page 340WARNING
If the power steering is not working then the steering wheel is much
more diffic u
lt to turn and the vehicle more difficult to control.
● The power steering only works when the engine is running.
● Never allow the vehicle to move when the engine is switched off.
● Never remove the key from the ignition if the vehicle is in motion. The
steerin
g may lock and it will not be possible to turn the steering wheel. Control and warning lamps lights up Possible cause Solution
(red) Power steering faulty. The steering system should be
chec
k
ed by a Technical Service
as soon as possible.
(yel-

If, after restarting the engine
and driving for a short distance,
the yellow warning light no lon-
ger comes on, it will not be nec-
essary to take the vehicle to a

engine cou
ld accidentally be started and electrical equipment such as
the windows could accidentally be operated resulting in serious injury.
● Never leave children or disabled people alone in the car. They could
be trapped in the c
ar in an emergency and will not be able to get them-
selves to safety. For example, depending on the time of the year, temper-
atures inside a locked and closed vehicle can be extremely high or ex-
tremely low resulting in serious injuries and illness or even death, partic-
ularly for young children.
● Never remove the key from the ignition if the vehicle is in motion. The
steerin
g may lock and it will not be possible to turn the steering wheel. Note
● If the key is left in the ignition lock with the engine off for long periods,
the v
ehicle battery will run flat.

Driving WARNING
Cold start sprays could explode or cause a sudden increase in the engine
speed.
● Nev er u
se start boosters. CAUTION
● An attempt to start the engine while driving or starting the engine imme-
di at
ely after turning it off can cause damage to the engine or starter motor.
● When the engine is cold, avoid high revs and heavy acceleration and do
not mak
e the engine work hard.
● Do not push or tow start the engine. Sunburnt fuel could damage the
catalytic
converter. For the sake of the environment
Do not warm the engine at idle speed; start driving immediately if the visi-
bi lity
is OK. This helps the engine reach operating temperature faster and
reduces emissions. Note
● For example, if the key battery is very worn or flat, the engine cannot be
s t
arted with the starter button. In this case, remove the ignition button from
the lock and insert the key.
● Electrical components with a high power consumption are switched off
temporari
ly when the engine starts.
● When the engine is started cold, there may be strong vibrations for a few
moments for t
echnical reasons. This is quite normal, and no cause for con-
cern.
● At temperatures below +5°C (+41°F), smoke may be given off below the
vehicl
e when the additional heater is connected. Stopping the engine Complete operations only in the sequence given:
Step
1. Stopping the vehicle completely
⇒ .
2. Press the brake pedal and keep pressed until step 4 has been
comp
l
eted. 3. In automatic gearboxes, put the selector lever in position
P. 4. Connect the electronic parking brake
⇒ page 183. 5. Turn the key in the ignition lock to position
⇒ fig. 127 0 .
6. With a manual gearbox, put the vehicle in first or reverse gear.
WARNING
Never switch off the engine while the vehicle is moving. You may lose
contr o
l of the vehicle and there is a risk of serious accident.
● The airbags and belt tensioners do not work when the ignition is
switc
hed off.
● The brake servo does not work when the engine is not running. To
stop
, the brake pedal must be pressed with more force.
● As the power steering does not work if the engine is not running, you
wil
l need more strength to steer than normally.
● If the key is removed from the ignition, the steering may lock and it
wil
l not be possible to steer the vehicle. CAUTION
If the engine has been driven at high speed for a prolonged period of time,
it m a
y overheat when turned off. To avoid engine damage, allow the engine
to run for approximately two minutes in neutral before switching it off. Safety First Operating instructions Practical tips Technical Data

Trailer towing
Trailer electric socket
The electric c
onnection between vehicle and trailer is a 13-pin socket. If the
trailer plug has seven pins, an adapter cable must be used.
Trailer rear lights
Check the trailer rear lights to ensure they work correctly and remain legal.
Ensure that the trailer does not use more than the maximum power
⇒ page 233.
Trailer connected to the antitheft alarm:
● When a vehicle comes from the factory fitted with an antitheft alarm and
tow hit
ch.
● When the trailer is connected to the vehicle using the socket.
● When the vehicle and trailer electrical systems work correctly and are
not dam
aged.
● When the vehicle is locked using the vehicle key and the antitheft alarm
is t
urned on.
When the vehicle is locked, the alarm is triggered when the electrical con-
nection between the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system before connecting or disconnect-
ing a trailer. Otherwise, the tilt sensor may erroneously activate the alarm. WARNING
Erroneous or unsuitable connection of electric cables may supply energy
to the tr ai
ler causing an anomaly in the vehicle electronics that could re-
sult in an accident with serious consequences.
● All work on the electrical system must be carried out only by a spe-
cia
list workshop.
● Never connect the trailer's electric system to the electrical connec-
tions of
the rear lights or any other power sources. CAUTION
Do not leave the trailer connected to the vehicle when parked; places on its
sup por
t wheel or its supports. For example, when changing the load or a
puncture, the vehicle will be pushed up or down. The force acting on the
tow hitch and the trailer could damage the vehicle or the trailer. Note
● In case of a fault in the vehicle or trailer electrical system or in case of
pr o
blems with the antitheft alarm system, have the system checked by a
specialist workshop.
● If the trailer accessories use energy from the socket when the engine is
stop
ped, the battery will be discharged.
● For technical reasons, trailers fitted with rear LED lights cannot be con-
nected to the antithef
t alarm system.
● If the vehicle battery is running low, the electrical connection with the
trail
er is automatically cut.
● With the engine running, the electrical equipment on the trailer will con-
sume pow
er.

The trai
l
er weight is the load that the vehicle can pull ⇒ . The drawbar
loa d i
s the vertical weight of the trailer hitch on the tow hitch ball
⇒ page 240.
The figures for trailer weights and draw bar weights given on the data plate
of the towing bracket are for values of this model only. The correct figures
for your specific vehicle, which may be lower than these figures for the tow
hitch, are given in the registration documents. The instructions in the offi-
cial vehicle documents take precedence.
