Seat belt tensioners, if the system determines
that deployment can offer additional protec-
tion for the vehicle occupants in this situation
R Windowbags on the driver's and front-
passenger side in certain situations if the
vehicle overturns and if the system deter-
mines that deployment can offer additional
protection to that provided by the seat belt
i Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other.
How the airbag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
R frontal collision
R side impact
R overturn PRE-SAFE
®
(anticipatory occupant
protection)
Introduction In certain hazardous situations, PRE-SAFE
®
takes pre-emptive measures to protect the vehi-
cle occupants.
Important safety notes !
Make sure that there are no objects in the
footwell or behind the seats. There is a risk
that the seats and/or the objects could be
damaged when PRE-SAFE ®
is activated.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. Always
adapt your driving style to suit the prevailing
road and weather conditions and maintain a
safe distance from the vehicle in front. Drive
carefully. Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under- steers or oversteers severely
R on vehicles with DISTRONIC PLUS: if Adaptive
Brake Assist intervenes powerfully
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected:
R the front seat belts are pre-tensioned
R if the vehicle skids, the side windows are
closed
R vehicles with the memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavourable
position
If the hazardous situation passes without result- ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back slightly
when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" (Y page 38). Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact: R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the electri-
cally adjustable steering wheel is raised when
the driver's door is opened 48

Running-in notes
Important safety notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective-
ness is not reached until the end of this teach-in process.
Brake pads/linings and discs that either are new or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. The first 1,500 km
The more you treat the engine with sufficient
care at the start, the more satisfied you will be
with the engine performance later on.
Observe the following notes on running-in the
engine: R you should therefore drive at varying road
speeds and engine speeds for the first
1,500 km.
R drive the vehicle mainly in drive program Cfor
the first 1,500 km.
R do not drive at speeds above 140 km/h for
the first 1,500 km.
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R do not exceed Ôof the maximum permitted
engine speed for each gear.
R in manual mode Mand temporary manual
drive program, shift up in good time.
R do not perform a RACE START.
R do not shift down a gear manually in order to
brake.
R try to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1,500 km, you can increase the engine
speed gradually and accelerate the vehicle to
full speed.
You should also observe these notes on running- 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
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. Driving

Connect the cable provided in the luggage
compartment to the trickle charger.
X Connect the trickle charger to 12 V socket :.
Consult the manufacturer's operating instruc- tions on how to do so.
The tailgate can be closed, even if a trickle
charger is connected. Make sure that the con-
nector for both the connector cables is outside
of the vehicle.
The connector can then separate if the vehicle is
moved, even if you forget to disconnect the con- nector cables. This prevents damaging the
cables and the trickle charger.
A trickle charger connected to 12 V socket :
only maintains the current charge level of the
vehicle's electrical system battery. If the vehi-
cle's electrical system battery is discharged, it
needs to be charged with a battery charger. Driving tips

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 rec-
ommended tyre pressure.
X Remove unnecessary loads.
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 Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. Brakes
Important safety notes G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Shift to a lower gear in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine, so less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do
not park the vehicle immediately. Drive on for a
short while. This allows the airflow to cool the
brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effectiveness.
To do this, brake more firmly from a higher
speed while paying attention to the traffic con-
ditions. This improves the grip of the brakes. Driving tips

After a short period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
The electric parking brake secures the vehicle
automatically if the HOLD function is activated,
the vehicle is stationary and:
R the driver's seat belt is not fastened and the
driver's door is open
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function
R a system fault occurs
R the power supply is insufficient
If the electric parking brake is not operational, a
horn will sound at regular intervals. The HOLD
function must then be deactivated.
If a malfunction occurs, the transmission may
also be shifted to position Pautomatically.
The Brake immediately Brake immediately message may also
appear in the multifunction display.
X Immediately depress the brake pedal firmly
until the warning message on the multifunc-
tion display goes out.
The HOLD function is deactivated. A horn will
sound at regular intervals if you turn off the
engine, take off your seat belt or open the driv-
er's door when the HOLD function is activated.
The horn alerts you to the fact that the HOLD
function is still activated. If you attempt to lock the vehicle, the tone becomes louder. The vehi-cle cannot be locked until you have deactivated
the HOLD function.
i Once you have switched off the engine, you
cannot restart it until you have deactivated
the HOLD function. RACE START
Important safety notes i
RACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, outside
of public road use.
RACE START enables optimum acceleration
from a standing start. For this, a suitably high-
grip road surface is required, along with the
tyres and vehicle being in good condition. G
WARNING
If you use RACE START, individual tyres may
get into a spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
i Observe the safety notes on driving safety
systems (Y page 54).
Be sure to read the safety notes and informa-
tion on ESP ®
(Y page 57).
Activation conditions You can activate RACE START if:
R the doors are closed
R the engine is running and the engine and
transmission are at operating temperature.
This is the case when the oil temperature
gauge in the multifunction display is shown in white (Y page 167).
R ESP ®
is functioning correctly (Y page 58)
R the steering wheel is in the straight-ahead
position
R the vehicle is stationary and the brake pedal is
depressed sufficiently (left foot)
R the transmission is in position D
R drive program S,S+ orRACE is selected
(Y page 108)
Activating RACE START i
When manual mode (Y
page 115) is active,
the transmission automatically shifts up to
RACE START in the drive program. This func-
tion supports maximum acceleration with
RACE START. After going through an acceler- ating process once from a stationary position,
this function is automatically deactivated.
X Depress the brake pedal with your left foot
and keep it depressed.
X Pull and hold both steering wheel gearshift
paddles.
