When the ignition is switched off, the seat heating and seat ventilation is also
switched off. If the engine is started again within 10 minutes, the driver's seat
heating and seat ventilation is automatically turned on again at the last set-
ting.WARNINGIf you have a subdued pain and/or temperature sensitivity, e.g. through
medication, paralysis or because of chronic illness (e.g. diabetes), we rec-
ommend not to use the seat heating. There may be difficult to heal burns. If
the seat heating is used, we recommend to make regular breaks in your
journey when driving long distances, so that the body can recuperate from
the stress of the journey. Please consult your doctor, who can evaluate
your specific condition.
CAUTION
The following instructions must be observed to avoid damage to the seats.■Do not kneel on the seats or otherwise apply concentrated pressure to them.■
Do not turn on any of the seat heaters if seats are not occupied.
■
Do not switch on the relevant seat heating if the seats have objects attached
to or placed on them, for example a child seat, a bag, etc.
■
When there are additional protective covers or protective covers mounted on
each of the seats, do not turn the seat heating on.
Note
If the on-board voltage decreases, the seat heating and ventilation switches
off automatically » page 216, Automatic load deactivation .

127
Stopping the engine
127
With the key in the ignition, the ignition can be switched on and off and the
engine can be started / stopped.
WARNING■ While driving with the engine stopped, the ignition must always be
switched on » page 127, Turn ignition on / off and start the engine .
■ With the ignition off, the steering may lock » page 127 - danger of an
accident!■
Do not withdraw the ignition key from the ignition lock until the vehicle
has come to a stop » page 134, Parking . Otherwise, the steering may lock -
danger of an accident!
■
Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury, accidents and dam-
age!
■
Never leave the vehicle unattended with the engine running - there is
risk of accident, damage or theft!
■
Never switch off the engine before the vehicle is stationary – risk of acci-
dent!
WARNING■ Never (e.g. in garages) run the engine in a closed place - there is the dan-
ger of poisoning and death!■
Do not leave any items (e.g. cloths or tools) in the engine compartment.
This presents a fire hazard and the risk of engine damage.
■
Never cover the engine with additional insulation material (e.g. with a
cover) – risk of fire!
CAUTION
■ Only start the engine when the engine and the vehicle are stationary - there
is a danger of starter and engine damage!■
Do not push-start the engine – risk of damaging the engine and the catalytic
converter. The battery from another vehicle can be used as a jump-start aid
» page 230 .
Note
Do not warm up the engine while the vehicle is stationary. If possible, start
your journey as soon as the engine has started. Through this, the engine rea-
ches its operating temperature faster.
Electronic immobilizer
Read and observe
and on page 126 first.
The electronic immobiliser (hereinafter referred to as the immobiliser) makesthe attempted theft or unauthorised use of your vehicle more difficult.
An electronic chip is integrated in the head of the key. The immobiliser is deac-
tivated with the aid of this chip when the key is inserted in the ignition lock.
As soon as the ignition key is removed from the ignition lock, the immobiliser is
automatically activated.
Operational problems
If the immobiliser components in the key fail, it is not possible to start the en-
gine. A message appears in the display of the instrument cluster to explain
that the immobiliser is active.
To start, use the other vehicle key or seek help from a specialist garage.
126Driving
Under certain circumstances (e.g. after switching off the ignition and opening
the driver's door), the steering is enabled only when the ignition is switched on
or the engine is started.WARNINGNever let the vehicle roll with locked steering lock - there is a risk of acci-
dent!

The ignition is switched on or off.
On vehicles fitted with a manual gearbox, the clutch pedal must not be de-
pressed while switching the ignition on or off, otherwise the system would try
to start.
On vehicles fitted with a automatic gearbox, the brake pedal must not be de-
pressed while switching the ignition on or off, otherwise the system would try
to start.
If the driver's door is opened while the ignition is on, an audible signal sounds
and the following message appears in the instrument cluster display.
Ignition switched on.IGNITION STILL ON
When leaving the vehicle always switch off the ignition.

Press the starter button » Fig. 162 on page 128 briefly – the engine starts au-
tomatically.
In vehicles with diesel engines after pressing the button, the glow plug warn-
ing light illuminates. The engine can be started after the indicator light goes
out.
Note
■ The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem.■
You should not switch on any major electrical components during the heat-
ing period otherwise the vehicle battery will be drained unnecessarily.
Switching off the engine

Press the button » Fig. 162 on page 128 briefly.
The engine and the ignition are switched off simultaneously.
Emergency shut-down
If necessary and in exceptional cases, the engine may even be turned off while
driving.
›
Press the starter button » Fig. 162 on page 128 for longer than 1 second or
twice within 1 second.
After the emergency stop of the engine, the steering lock will remain un-
locked.
CAUTION
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumula-
tion of heat when the engine is switched off.
Note
After switching off the ignition, the radiator fan may intermittently continue to
operate for approx. 10 minutes.129Starting-off and Driving

START-STOPsystem
Introduction
This chapter contains information on the following subjects:
Operation
131
Manually deactivating/activating the system
132
Information messages
132
The START-STOPsystem (hereinafter referred to as the system) reduces
CO 2emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
or is at a standstill (e.g. at the traffic lights), it turns off the engine and starts it
again when moving off.
The system function depends on many factors. Some of them are down to the
driver, while others are systemic and can neither be influenced nor identified.
For this reason, the system may react differently in situations which seem
identical from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even when it has previously been manually deactivated with the
button).
Note
If the engine has stopped due to the system, the ignition remains switched on.130Driving
