The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer a risk of collision
R there is no longer an obstacle detected in
front of your vehicle STEER CONTROL
General notes STEER CONTROL is only available in vehicles
without 4MATIC.
STEER CONTROL helps you by transmitting a noticeable steering force to the steering
wheel in the direction required for vehicle
stabilisation.
This steering support is provided in particular
if:
R both right wheels or both left wheels are on
a wet or slippery road surface when you
brake
R the vehicle starts to skid
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 74).
No steering support is provided from STEER
CONTROL, if:
R ESP ®
is malfunctioning
R the steering is faulty
If ESP ®
is malfunctioning, you will be assisted
further by the electrical power steering. Protection against theft
Immobiliser
The immobiliser prevents your vehicle from
being started without the correct key. X
To activate with the key: remove the key
from the ignition lock.
X To activate with KEYLESS-GO start-
function or KEYLESS-GO: switch the igni-
tion off and open the driver's door.
X To deactivate: switch on the ignition.
When leaving the vehicle, always take the key with you and lock the vehicle. Anyone can
start the engine if a valid key has been left
inside the vehicle.
i The immobiliser is always deactivated
when you start the engine. ATA (Anti-Theft Alarm system)

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
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle has been delivered or after repairs. Full sys-
tem effectiveness is not reached until the end
of this teach-in procedure.
Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres 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 road 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 When changing gears manually, change up
in good time, before the rev counter needle
reaches Ôof the way to the red area of the
rev counter. R
Do not shift down a gear manually in order
to brake.
R Vehicles with automatic transmission: try
to avoid depressing the accelerator pedal
beyond the point of resistance (kickdown).
After 1,500 km, you may gradually accelerate the vehicle to full road and engine speeds.
You should also observe these notes on run-
ning-in if the engine or parts of the drive train
on your vehicle have been replaced.
Always observe the applicable speed limit. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another. 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 180

Automatic transmission
Important safety notes
G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate. 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.
Bear in mind that power transmission
between the engine and the transmission is
interrupted when the engine is switched off.
For this reason, shift the automatic transmis-
sion to Pwhen the engine is switched off and
the vehicle is stationary. Apply the electric
parking brake to prevent the vehicle from roll- ing away.

tions for hybrid vehicles (Y page 269). DIRECT SELECT lever

WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G

Emergency braking
The vehicle can also be braked during an
emergency by using the electric parking
brake.
X While driving, push handle :of the elec-
trical parking brake (Y page 209).
The vehicle is braked as long as you keep
handle :of the electric parking brake
depressed. The longer the electric parking
brake handle :is depressed, the greater the
braking force.
During braking:
R a warning tone sounds
R the Release park. brake

When the vehicle has been braked to a stand- still, the electric parking brake is applied. Parking up the vehicle
If you leave the vehicle parked up for longer
than four weeks, the battery may be damaged by exhaustive discharging and further dam-
aged in the event of this occurring again.
X Disconnect the battery or connect it to a
trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked up for longer
than six weeks, it may suffer from lack of use.
X Visit a qualified specialist workshop and
seek advice.

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.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tyres should always be inflated to the
recommended tyre pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Service Booklet or by the service interval
display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic, on
short journeys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists
you in achieving the most economical driving
style for the selected settings and prevailing
conditions. Consumption can be significantly influenced by your driving style. Driving tips
