Electrical power socket* Introduction
Electrical equipment can be connected to the socket in the vehicle.
Connected equipment must be in perfect condition and show no signs of
faults.
Additional information and warnings:
● Cigarette lighter ⇒ page 115
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Improper use of the socket or electrical devices could lead to a fire and
cause serious injuries.
● Never leave children unsupervised in the vehicle. The socket and
equipment connected to it can be used when the ignition is switched on.
● Should a connected electrical device overheat, switch it off and un-
plug it immediately.
CAUTION
● To avoid damage to the vehicle's electrical system, never connect equip-
ment that generates electrical current, such as solar panels or battery charg-
ers, to the 12 Volt sockets in order to charge the vehicle's battery.
● Only use accessories with approved electromagnetic compatibility ac-
cording to current regulations. ●
To avoid damage due to voltage variations, switch off all appliances con-
nected to the 12 V socket before switching the ignition on or off and before
starting the engine.
● Never connect an appliance to the 12 Volt socket that consumes more
than the power indicated in watts. Exceeding the maximum power absorp-
tion could damage the vehicle's electrical system.
For the sake of the environment
Do not leave the engine running when the vehicle is at a standstill.
Note
Using electrical appliances with the engine stopped and the ignition switch-
ed on will drain the battery.
Note
Unshielded equipment can cause interference on the radio system equip-
ment and the vehicle's electrical system.
Note
If electrical equipment is used near an aerial, you may observe interference
in the reception of AM stations. 

WARNING
Switching off the engine while driving makes stopping the vehicle diffi-
cult. As a consequence you may lose control of the vehicle and there is a
risk of serious accident.
● The assisted braking and steering systems, the airbag system, safety
belts and certain safety equipment are only active while the engine is
running.
● The engine should only be switched off when the vehicle is at a
standstill.
WARNING
While the engine is running or starting it could help reduce the risk of se-
rious injury.
● Never start or leave the engine running in poorly ventilated or closed
spaces. Exhaust gas contains carbon monoxide, a toxic, colourless and
odourless gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
● Never leave the vehicle unattended if the engine is running. The vehi-
cle could move off suddenly or something unexpected could happen re-
sulting in damage and serious injury.
● Never use start boosters. Cold start sprays could explode or increase
the engine speed unexpectedly. 

WARNING
Unsuitable or careless use of the vehicle key could result in serious in-
jury.
● Always take all the keys with you whenever you leave the vehicle. The
engine could accidentally be started and electrical equipment such as
the windows could accidentally be operated resulting in serious injury.
● Never leave children or disabled people alone in the vehicle. They
could be trapped in the vehicle in an emergency and will not be able to
get themselves to safety. For example, depending on the time of the
year, temperatures inside a locked and closed vehicle can be extremely
high or extremely low resulting in serious injuries and illness or even
death, particularly for young children.
● 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.
Note
● If the key is left in the ignition lock with the engine off for long periods,
the vehicle battery will run flat.
● For automatic gearbox vehicles the key can only be removed from the ig-
nition lock if the gear selector lever is in position P. In this case, press and
release the selector lever locking button. 

Do not allow floor mats or other objects to obstruct the free passage of the
pedals.
Floor mats should leave the pedal area vacant and unobstructed and be cor-
rectly secured in the footwell zone. In the event of failure of a brake circuit, the brake pedal must be pressed
harder than normal to brake the vehicle.
WARNING
Objects falling into the driver's footwell could prevent use of the pedals.
This could lead the driver to lose control of the vehicle, increasing the
risk of a serious accident.
● Make sure the pedals can be used at all times, with no objects rolling
underneath them.
● Always secure the mat in the footwell.
● Never place other mats or rugs on top of the original mat supplied by
the factory.
● Ensure that no objects can fall into the driver's footwell while the ve-
hicle is in motion.
CAUTION
The pedals must always have free and unobstructed passage to the floor.
For example, in case of a fault in the brake circuit, the brake pedal will need
to be pressed further to stop the vehicle. To press the brake pedal down fur-
ther will require more force than usual. 

Using Tiptronic
● Place the lever in the position D to the left on the Tiptronic shift gate M
⇒ 
in Automatic gearbox: engaging a gear on page 130.
● Press the lever forwards + or backwards – to move up or down a gear
⇒ Fig. 89.
● Place the lever back to the position M to the left on the Tiptronic shift
gate, to leave Tiptronic mode ⇒ 
in Automatic gearbox: engaging a gear
on page 130.
With the lever in the position D, and pressing forwards +
or backwards –the Tiptronic programme can be selected
M.
CAUTION
● When accelerating, the gearbox automatically shifts up into the next
gear shortly before the maximum engine speed is reached.
● When reducing speed manually, the gear box only shifts gear when the
engine can no longer exceed the maximum engine speed. 
Driving with an automatic gearbox
The gearbox changes up or down gears automatically as the vehicle moves.
Driving down hills
The steeper the gradient, the lower the gear you will need to select. The low-
est gears increase the engine braking work. Never go down hills with the se-
lector lever in neutral N.
● You should reduce speed accordingly.
● Place the lever in the position D to the left on the Tiptronic shift gate M
⇒  page 130.
● Gently pull the selector lever back –
to change down a gear. Starting when going up a slope
The steeper the gradient, the lower the gear you will need.
When stopping on a slope with a gear range engaged, the vehicle must be
prevented from rolling backwards by always pressing the brake pedal or
pulling the handbrake lever up. When starting, release the brake pedal or
the handbrake ⇒ 
.
Kickdown
The kickdown system provides maximum acceleration when the gear selec-
tor lever is in the position D, or in the Tiptronic position M.
When the accelerator pedal is pressed right down, the automatic gearbox
will shift down to a lower gear, depending on road speed and engine speed.
This takes advantage of the maximum acceleration of the vehicle ⇒ 
.
When the accelerator is pressed to the floor, the automatic gearbox shifts to
the next gear only after the engine reaches the specified maximum engine
speed.
WARNING
Rapid acceleration can cause loss of traction and skidding, especially on
slippery ground. This could cause loss of control of the vehicle resulting
in an accident and serious injury.
● Always adapt your driving style to suit the flow of traffic.
● Only use the kickdown function or rapid acceleration if visibility,
weather, road and traffic conditions so permit.
● Never put other road users in danger by accelerating or with your
driving style.
CAUTION
If you stop on a hill with a gear range engaged, do not try to prevent the
vehicle from rolling back by pressing on the accelerator. Otherwise, the au-
tomatic gearbox may overheat causing damage. 
