Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 27). Running-in notes
Important safety notes
New brake pads/brake pads and discs that
have been replaced only achieve optimum
braking effect after several hundred kilome-
tres of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedal. The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, before the rev
counter needle is Ôof the way to the red
area of the rev counter.
R Do not shift down a gear manually in order
to brake. Vehicles with automatic transmission:
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain.
After 1,500 km, you may gradually accelerate
the vehicle to full road and engine speeds.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardised. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Fit the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats. G
WARNING
Unsuitable footwear can hinder correct usage
of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake 146

boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train. Key positions
Key g
To remove the key
1 Power supply for some consumers, such
as the windscreen wipers
2 Ignition (power supply for all consumers)
and drive position
3 To start the engine The steering wheel is locked when the key is
removed from the ignition lock.
i
If the key does not belong to the vehicle,
it can still be turned in the ignition lock.
However, the ignition will not be switched
on. The engine cannot be started.
KEYLESS-GO General notes
R
Do not keep the KEYLESS-GO key with:
-electronic devices, e.g. a mobile phone
or another key
- metallic objects, e.g. coins or metal film
- metallic objects, e.g. a metal case
This can affect the function of the key with
KEYLESS-GO.
Vehicles with KEYLESS-GO are equipped with
a key featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
The Start/Stop button must be inserted in the
ignition lock and the key must be in the vehi-
cle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately. Driving

Parking
Important safety notes
G
WARNING
If flammable materials such as leaves, grass
or twigs are exposed to prolonged contact to
parts of the exhaust system that heat up, they
could ignite. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's equip-
ment. There is a risk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unsupervised in the vehicle.
! A moving vehicle can lead to damage to
the vehicle or damage to the drive train.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied.
R on vehicles with manual transmission,
engage first gear or reverse gear. R
on vehicles with automatic transmission,
the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on uphill or downhill gradients, the front
wheels must be turned towards the kerb. Switching off the engine
Important safety notes G
WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of
an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.

with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and existing conditions. Con-
sumption can be significantly influenced by
your driving style. Example: ECO display
The ECO display consists of three bars:
R acceleration
R smooth driving
R coasting
The percentage count is the mean value of the
three bar values. The three bars and the mean
value begin at the value of 50%. A higher per-
centage count indicates a more economical
driving style.
The ECO display does not indicate the actual
fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption figure in l/100 km.
In addition to driving style, the consumption
is affected by many other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers These factors are not included in the ECO dis-
play.
The evaluation of your driving style takes the
following three categories into consideration:
Acceleration (evaluation of all accelera-
tion processes) The bar fills up: The bar empties:
Moderate accelera-
tion, especially at
higher speeds Sporty acceleration
Smooth driving (assessment of driving
behaviour at all times)
The bar fills up: The bar empties:
Constant speed and
avoidance of unnec-
essary acceleration
and deceleration Fluctuations in
speed
Coasting (assessment of all deceleration
processes)
The bar fills up: The bar empties:
Anticipatory driving,
keeping your dis-
tance and early
release of the accel-
erator: the vehicle
can coast without
use of the brakes Frequent braking
i
An economical driving style involves driv-
ing with a moderate engine speed.
To achieve a higher value in the categories
"acceleration" and "smooth driving":
R observe the gearshift recommendation.
R drive the vehicle in drive program E(vehi-
cles with automatic transmission).
i On long journeys at a constant speed, e.g.
on the motorway, only the bar for "smooth
driving" will change. 166
