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-
lo w) Power steering operation re-
duced. The steering system should be
chec
k
ed by a Technical Service
as soon as possible.
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
specialised workshop. The vehicle battery was dis-
connect
ed and h
as been re-
connected. Drive for a short distance at 15 –
20 km/h.

You should obtain professional
assistance. Several warning and control lamps should light up for a few seconds when
the ignition is
sw
itched. This signals that the lamp is working properly. They
will switch off after a few seconds. WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or m a
y cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps and text messages when they appear
ma y
result in faults in the vehicle. Information on the steering Steering column electronic lock
If the driv
er's
door is opened before the ignition is switched off, the steering
column electronic lock is activated via the ignition key or the sensor built
into the door handle.

To prevent theft, we recommend you lock the steering before leaving the ve-

With the po
w
er steering system, the assisted steering function automatical-
ly adjusts according to the vehicle speed, the steering torque and the wheel

You should remember that you will need considerably more power than nor-
mal to steer the vehicle if the power steering is not working correctly or not
at all.
Counter steering assistance system
The counter steering assistance system helps the driver in critical situa-
tions. Additional steering power helps the driver when counter steering.

169
Driving WARNING
The counter steering assistance system combined with ESC (ESP) helps
the driver t o s
teer the vehicle in critical driving conditions. At all times, it
is the driver who steers the vehicle. The counter steering system does
not steer the vehicle.

eerin
g wheel adjust-
ment.
Adjust the steering wheel before your trip and only when the vehicle is sta-
tionary
.
● Push the lever ⇒ fig. 126 1 downwards.
● Adjust the steering wheel so that you can hold onto the steering wheel
with both h and
s on the outside of the ring at the 9 o'clock and 3 o'clock
positions and your arms slightly bent.
● Push the lever firmly upwards until it is flush to the steering column
⇒ . WARNING
Incorrect use of the steering wheel adjustment function and an incorrect
adju s
tment of the steering wheel can result in severe or fatal injury.
● After adjusting the steering column, push the lever 1 firmly upwards
to en s
ure the steering wheel does not accidentally change position while
driving.
● Never adjust the steering wheel while the vehicle is in motion. If you
need to adju
st the steering wheel while the vehicle is in motion, stop
safely and make the proper adjustment.
● The adjusted steering wheel should be facing your chest and not your
face so a
s not to hinder the driver's frontal airbag protection in the event
of an accident.
● When driving, always hold the steering wheel with both hands on the
outside of
the ring at the 9 o'clock and 3 o'clock positions to reduce inju-
ries when the driver's frontal airbag deploys.
● Never hold the steering wheel at the 12 o'clock position or in any oth-
er manner (e.g. in the c
entre of the steering wheel). In such cases, if the
driver's airbag deploys, you may sustain injuries to your arms, hands and
head.

s could even result in the loss of control causing an accident with
serious consequences.
● The assisted braking and steering systems, the airbag system, safety
belts and c
ertain safety equipment are only active while the engine is
running.
● The engine should only be switched off when the vehicle is at a
stand
still. WARNING
While the engine is running or starting it could help reduce the risk of se-
rious injur
y.
● Never start or leave the engine running in poorly ventilated or closed
spac
es. Exhaust gas contains carbon monoxide, a toxic, colourless and
odourless gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
● Never leave the vehicle unattended if the engine is running. The vehi-
cle c
ould move off suddenly or something unexpected could happen re-
sulting in damage and serious injury.
● Never use start boosters. Cold start sprays could explode or increase
the engine speed u
nexpectedly.

Driving WARNING
The components of the exhaust system reach very high temperatures.
This c
ould cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in cont
act with flammable materials (such as wood, leaves, spilled
fuel, dried grass, etc).
● Do not apply additional underseal or anti-corrosion coatings to the
exhau
st pipes, catalytic converter, heat shields or the diesel particulate
filter.

Key not authorised for the vehicle
If a k ey
which is not authorised for this vehicle is inserted in the ignition
lock, it can be removed as follows:
● Automatic gearbox: the key cannot be removed from the ignition lock.
Pres
s and release the selector lever locking button. Key can be removed
from the vehicle.
● Manual gearbox: Remove the key from the ignition. WARNING
Unsuitable or careless use of the vehicle key could result in serious in-
jury .
● A
lways take all the keys with you whenever you leave the vehicle. The
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.
● For automatic gearbox vehicles the key
can only be removed from the ig-
nition lock if the gear selector lever is in position P. In this case, press and
release the selector lever locking button. Starting the engine Complete operations only in the sequence given:
