Information messages
116
The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle phase, e.g. when stopped at traffic lights. The engine restarts automatically
where necessary.
The system can work only if the following basic conditions are met. The driver's door is closed.
The driver has fastened the seat belt. The bonnet is closed.The driving speed exceeded 4 km/h after the last stop.
No trailer is coupled.
WARNING■ The brake servo unit and power steering only operate if the engine is run-
ning.■
Never let the vehicle roll with the engine switched off.
CAUTION
Always deactivate the START-STOP system before driving through wa-
ter » page 108 .Note■
If the driver's seat belt is removed for more than 30 seconds or the driver's door
is opened during stop mode, the engine will have to be started manually.■
After manually starting the engine, automatic engine shut down is not possible
until the vehicle has travelled the required minimum distance for START-STOP mode.
■
Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out-
doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable
temperature for proper operation of the START STOP system.
■
If Climatronic is running in automatic mode, the engine may not switch off auto-
matically under certain conditions.
Starting/shutting down the engine

What influences the driving safety?First read and observe the introductory information and safety warn-ings
on page 123.
The driver is fully responsible for himself and his occupants. If your driving safety is effected, you place yourself and the oncoming traffic at risk.
The following guidelines must therefore be observed. › Do not become distracted from concentrating on the traffic situation, e.g. by
your passengers or mobile phone calls.
› Never drive when your driving ability is impaired, e.g. due to medication, alcohol
or drugs.
› Keep to the traffic regulations and the permissible speed limit.
› Always adjust the driving speed to the road, traffic and weather conditions.
› Take regular breaks on long journeys – at least every two hours.
Correct seated position
Introduction
This chapter contains information on the following subjects:
Correct seated position for the driver
125
Correct seated position for the front passenger
125
Correct seated position for the passengers in the rear seats
125
Examples of incorrect seated positions
125WARNINGGeneral information■The front seats and head restraints must be adjusted to match the body
size at all times and the seat belt must always be fastened properly to provide the most effective levels of protection to the passengers.■
If the occupant adopts an incorrect seated position, he is exposed to life-
threatening injuries, in case he is hit by a deployed airbag.
■
If the occupants on the rear seats are not sitting upright, the risk of injury is
increased due to incorrect routing of the seat belt.
■
The seat backrests must not be tilted too far back when driving, as this will
impair the function of the seat belts and of the airbag system – risk of injury!
WARNINGInformation for the driver■Always assume the correct seated position before setting off and do not
change this position while driving. Also advise your passengers to adopt the
correct seated position and not to change this position while the car is mov-
ing.■
Maintain a distance of at least 25 cm to the steering wheel. Not maintaining
this minimum distance will mean that the airbag system will not be able to
properly protect you - hazard!
■
When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel in
the 12 o'clock position or in any other way (e.g. in the middle or inner edge of
the steering wheel). In such cases, you could severely injure the arms, hands
and head when the driver airbag is deployed.
■
Ensure that there are no objects in the driver's footwell, as these may get
caught in the pedal apparatus when driving or braking. You would then no longer be able to operate the clutch, brake or acceleration pedals.
WARNINGInformation for the front seat passenger■Maintain a distance of at least 25 cm from the dash panel. Not maintaining
this minimum distance will mean that the airbag system will not be able to
properly protect you - there is a risk that you could be killed.■
Always keep your feet in the footwell when the car is being driven - never
place your feet on the instrument panel, out of the window or on the seats.
You will be exposed to increased risk of injury if it becomes necessary to apply
the brakes or in the event of an accident. You may suffer fatal injuries when
an airbag is deployed if you have adopted an incorrect seating position.

Jump-starting in vehicles with the START-STOP systemFig. 150
Engine compartment: Earth
First read and observe the introductory information and safety warn-ings on page 186.
The jump-start cable must only be connected to the engine earthing point on ve-
hicles with the START-STOP system » Fig. 150.
Towing the vehicle
Introduction
This chapter contains information on the following subjects:
Front towing eye
189
Rear towing eye
189
Vehicles with a tow hitch
189
Vehicles with manual transmission may be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
The following guidelines must be observed when towing.
Driver of the tow vehicle›Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.›
On vehicles with a manual transmission, only push down on the accelerator pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not locked and so that the turn signal lights, horn, windscreen wipers and windscreen washer system can
be used.
›
Take the vehicle out of gear or move the selector lever into position N if the ve-
hicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
CAUTION
■ Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-start
aid » page 186 , Jump-starting .■
If the gearbox no longer contains any oil because of a defect, your vehicle must
only be towed with the driven wheels raised clear of the ground or on a special
breakdown vehicle or trailer.
■
The vehicle must be transported on a special breakdown vehicle or trailer if it is
not possible to tow in the vehicle in the way described or if the towing distance is greater than 50 km.
■
To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
■
While towing, take care to avoid impermissibly high tensile forces or jerky loads.
There is always a risk of excessive stresses and damage resulting at the points to
which you attach the tow rope or tow bar when you attempt to tow a vehicle
which is not standing on a paved road.
■
Attach the tow rope or the tow bar to the towing eyes » page 189
or » page 189 to the detachable ball head of the towing equipment » page 117 .
