People who, because of medications, paraly-
si s

or chronic diseases (e.g. diabetes) cannot
perceive pain or temperature, or have a limi-
ted perception thereof, may suffer burns to
the back, buttocks or legs when using seat
heating, an occurrence that may entail a very
lengthy recovery period or from which it may
not be possible to recover fully. Seek medical
advice if you have doubts regarding your
health.
● People with limited pain and temperature
thresho
lds must never use seat heating. WARNING
If the fabric of the cushion is wet, this can ad-
ver sely

affect the operation of the seat heat-
ing, increasing the risk of burns.
● Make sure the seat cushion is dry prior to
usin
g the seat heater.
● Do not sit on the seat with clothing that is
wet or d
amp.
● Do not leave clothing that is wet or damp
on the seat. ●
Do not s pi

ll liquid on the seat. CAUTION
● To av oid d

amaging the heating elements of
the seat heaters, please do not kneel on the
seat or apply sharp pressure to a single point
on the seat cushion or backrest.
● Liquids, sharps objects and insulating ma-
teria
ls (e.g. covers or child seats) can damage
the seat heating.
● In the event of smells, switch off the seat
heating immedi
ately and have it inspected by
a specialised workshop. For the sake of the environment
The seat heating should remain on only when
needed. Otherw i

se, it is an unnecessary fuel
waste. Front centre armrest

››› page 169.
1.Press and hold the brake pedal until step 5 is
performed.
1a.In vehicles with a manual gearbox: press and
hold the clutch down until the engine starts.
2.Put the gearbox lever in neutral or the selector
lever in position P or N.
3.
Briefly press the starter button ››› Fig. 187 with-
out pressing the accelerator. For the engine to
start there must be a valid key in the vehicle.
After starting the engine, the light of the START ENGINE STOP
button changes to a fixed
light indicating that the engine has started.
4.If the engine does not start, stop and wait for
approx. 1 minute before trying again. If neces-
sary, perform an emergency start ››› page 170.
5.Disconnect the electronic parking brake when
you are about to start driving ››› page 172. WARNING
Never leave the vehicle with the engine run-
ning, e s

pecially if a gear or gear range is en-
gaged. The vehicle could then suddenly move
or something strange could happen that
would cause damage, fire or serious injury. WARNING
Cold start sprays could explode or cause a
sud den inc

rease in the engine speed.
● Never use sprays to cold start the engine. CAUTION
● The st ar

ter motor or the engine may be
damaged if you try to start the engine while
driving or if you restart it immediately after
switching it off.
● If the engine is cold, avoid high engine
speeds, p
ushing the engine too hard and rap-
id acceleration.
● Do not start the engine by pushing the ve-
hicle or t
owing it. Unburnt fuel could enter
the catalytic converter and damage it. Note
● Do not w ait

until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions. ●
Electric a

l components with a high power
consumption are switched off temporarily
when the engine starts.
● When starting with a cold engine, noise
level
s may briefly increase. This is quite nor-
mal, and no cause for concern.
● When the outside temperature is below
+5°C (+41°F), if the en
gine is diesel, some
smoke may appear under the vehicle when the fuel-operated auxiliary heater is on. Stopping the engine

Advice
In these situations you will be aware that the
po w
er m
anagement system is intervening to
control the distribution of electrical power.
When the vehicle is parked for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power manage-
ment will gradually shut off the electrical de-
vices one by one or reduce the amount of cur-
rent they are using. This limits the amount of
power consumed and helps to ensure relia-
ble starting even after a long period. Some
convenience functions, such as remote vehi-
cle opening, may not be available under cer-
tain circumstances. These functions will be
restored when you switch on the ignition and
start the engine.
With the engine switched off
For example, if you listen to the sound sys-
tem with the engine switched off the battery
will run down.
If the energy consumption means there is a
risk that the engine will not start, a text will
appear in vehicles with a driver information
system*.
This driver indicator tells you that you must
start the engine so that the battery can re-
charge. When the engine is running
Although the altern
ator generates electrical
power, the battery can still become dis-
charged while the vehicle is being driven.
This can occur when a lot of power is being
consumed but only a small amount supplied,
especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Checking and refilling levels

If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the
fuel tank is “full”. Do not try to put in more
fuel after the nozzle cuts out, as this will fill
the expansion chamber in the fuel tank.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. Further notes on fuel can be found at

Every 6 months it is necessary to run on pet-
rol until the control lamp switches off  and
then the tank must be refilled. This is neces-
sary to ensure that the system works proper-
ly, as well as the fuel quality required for driv-
ing with petrol.
