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 vehicle comes to a standstill.
● Apply the handbrake firmly ⇒ page 136.
● For an automatic gearbox, move the selector lever to position P.
● Switch off the engine and release the brake pedal.
● Remove the key from the ignition.
● If necessary, turn the steering wheel slightly to lock the steering.
● With a manual gearbox, engage the 1st gear on flat ground and slopes,
or even the reverse gear on hills, and release the clutch pedal.
● Ensure that all passengers leave the vehicle, especially children.
● When leaving the vehicle, take all keys with you.
● Locking the vehicle.
Additional information for steep slopes and hills
Before switching off the engine, rotate the steering wheel so that if the vehi-
cle should move then 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, spilled
fuel, dried grass, etc).
CAUTION
● Special care should be taken when parking in areas with high kerbs or
fixed barriers. Objects protruding from the ground may damage the bumper
or other parts of the vehicle during manoeuvres. To avoid damage, stop be-
fore the wheels touched the barrier or kerb.
● Special attention is required when driving through entrances, over
ramps, kerbs or other 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 (120 to 190 mph), the new brake pads have not
yet reached their maximum braking capacity, and need to be “run in” first
⇒ 
. The slightly reduced braking effect can be compensated for by in-
creasing pressure on the brake pedal. While running in, the full braking dis-
tance or emergency braking distance is larger then when the brake pads
have been run in. While running in, avoid full power braking or situations
requiring braking performance. For example, in heavy traffic.
The rate of wear of the brake pads depends to a great extent on the condi-
tions in which the vehicle is used and the way the vehicle is driven. If the
vehicle is used frequently in city traffic or for short trips or driven sport style,
visit a Specialised workshop regularly more frequently than advised in the
Maintenance Programme to have the brake pads checked.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). At higher
speed, “dry” the brakes as quickly as possible by braking gently several
times. Only do this without endangering vehicles behind you or any other
road users ⇒

Steering Introduction
The power steering* is not hydraulic but electromechanical. The advantage
of this 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 electromechanical steering system, the power steering function au-
tomatically adjusts according to the vehicle speed, the steering torque and
the wheel turning angle. The electromechanical steering only works when
the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 119
● Vehicle battery ⇒ page 193
● Tow-starting and towing away ⇒ page 276
WARNING
If the power steering is not working then the steering wheel is much
more difficult 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
steering may lock and it will not be possible to turn the steering wheel.

In the engine compartment
WARNING (Continued)
● Never open the bonnet if you see steam or coolant escaping from the
engine compartment. Hot vapours and coolant can cause serious burns.
Always wait until you cannot see or hear the sound of steam or coolant
coming from the engine compartment.
● Always allow the engine to cool down before opening the bonnet.
● Contact with hot elements of the engine and the exhaust system can
cause burns.
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Engage the handbrake and place the gear selector lever in P or the
gear stick in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the coolant expansion tank when the engine
is hot. Otherwise, coolant may spray out under pressure causing burns
and serious injury.
–After cooling, carefully and slowly unscrew the cap anticlockwise,
gently pressing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
● Never cause short circuits in the electrical system. The battery could
explode.
● To minimise the risk of electric shock and serious consequences
while the engine is running or starting the engine, note the following:
–Never touch the electrical wiring of the ignition system.
WARNING
In the engine compartment, there are rotating parts that could cause se-
rious injury.
● Never place your hands directly on or near the radiator fan. Touching
the rotor blades could seriously harm you. The ventilator works accord-
ing to the engine temperature and could start suddenly even when the ig-
nition is turned off and the key is removed.
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan
etc as well as from the high-voltage ignition system. Always work with
the utmost caution.
–Always make sure that no parts of your body, jewellery, ties, loose
clothing and long hair can be trapped by the rotating parts of the en-
gine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back and tie all items of loose clothing to your body to make
sure that they cannot be trapped by engine components.
– Take extreme caution when operating the accelerator and remain
attentive. The vehicle could move, even if the handbrake is applied.
● Always make sure you have not left any objects, such as cloths or
tools, in the engine compartment. If any object is left in the engine com-
partment, this could cause malfunctions, engine faults and even a fire. 
