Operation
WARNING
Never programme the auxiliary heater so that
it sw it
ches itself on and is running in an en-
closed space or an area with no ventilation.
The auxiliary heater exhaust fumes contain
carbon monoxide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death. Operating instructions
The auxiliary heater exhaust system located
belo
w the
v
ehicle must be kept clear of snow,
mud and other objects. The exhaust fumes
must be able to exit freely. The emissions
generated by the auxiliary heater are re-
moved via an exhaust pipe fitted underneath
the vehicle.
On heating the vehicle interior, depending on
the outside temperature, the warm air is first
directed at the windscreen and then to the
rest of the vehicle interior through the air
vents. Directing the diffusers – towards the
windows for example – can affect air distribu-
tion.
When will the auxiliary heater not be activa-
ted?
● The auxiliary heater requires about as
much po w
er as the dipped beam headlights.
If the 12-volt battery charge is too low, the auxiliary heater switches off automatically
and cannot
be sw
itched on. This avoids prob-
lems when starting the engine.
● The heating must be activated every time
you want
to set off. Similarly, the departure
time must reactivate each time.
● The control lamp (fuel l
evel indicator)
lights up. Note
● Noise s
will be heard while the auxiliary
heater is running.
● When the air humidity is high and the in-
side temper
ature low, condensation from the
heating and ventilating system may evapo-
rate when the auxiliary heater is switched on.
In this case, steam may be released from un-
derneath the vehicle. This does not mean
that there is a vehicle malfunction.
● If the vehicle is tilted, e.g. if parked on a
slope, the operation of
the auxiliary heater
may be restricted if the fuel tank level is low
(just above the reserve level).
● If the auxiliary heater is used a number of
times f
or a long period of time, the 12-volt
battery will lose its charge. To recharge the
battery, the vehicle must be driven for a num-
ber of kilometres from time to time. As a
guideline: The journey should last approxi-
mately as long as the heater was connected.
● At temperatures below +5°C (+41°F), the
auxili
ary heater may switch itself on automat-
ically when the engine is switched on. The auxiliary heater is switched off again after a
cer
t
ain time.180
Operation
WARNING
● Never ru n the en
gine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
extr eme lo
ad conditions until the engine has
reached its normal operating temperature,
otherwise this can damage the engine. For the sake of the environment
Do not warm up the engine by idling it. You
shoul d driv
e off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it i
s difficult to turn the ignition key to
the position 2 , turn the steering wheel to
both side s
to release the steering lock.
● When starting from cold, the engine may be
a little noisy
for the first few seconds until oil
pressure has built up in the hydraulic valve
lifters. This is quite normal, and no cause for
concern.
● If the vehicle battery is disconnected and
reconnect
ed, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up.
● Vehic
les with automatic gearbox: depend-
ing on the cou
ntry, after switching off the ig-
nition, you can only remove the ignition key if the selector lever is in position “P” (parking
lock). Ne
xt, the sel
ector lever is locked. Switching off the engine with the key

ossible vehicle theft is prevented with the
steering lock engaged. WARNING
● Never sw it
ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury. ●
Never r emo
ve the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
leav
e the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
loa d f
or a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
After the engine is switched off the radiator
fan m a
y run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation. 182

Avoid carrying unnecessary loads
Giv en th
at
every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. At speeds of 100-120
km/h (62-75 mph), this will save 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off
any unneeded electrical devices. Devices that
use a lot of electricity includes the blower at
a high setting, the rear window heating or
the seat heating*.
Power management
This sy
stem helps to ensure reliable
starting The power management controls the distribu-
tion of
el
ectric
al energy and thus helps to en-
sure that there is always enough power avail-
able to start the engine. If a vehicle with a conventional electrical sys-
tem is
left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of
the battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynamic
power management.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sen-
sors detect the battery voltage, battery cur-
rent and battery temperature. This enables
the system to calculate the current power lev-
el and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is switched off. The system takes the battery di-
agnosi
s data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
● Neither is the po
wer management system
able to overcome the given physical limits.
Please remember that the power and useful
life of the battery are limited.
● When there is a risk that the vehicle will
not st
art, the alternator power failure or low
battery charge level warning lamp will be
shown ››› page 119. Flat battery

Operation
Short trips, city traffic and low temperatures
al l
p
lace a heavy load on the battery. In these
conditions a large amount of power is con-
sumed, but only a small amount is supplied.
The situation is also critical if electrical devi-
ces are in use when the engine is not run-
ning. In this case power is consumed when
none is being generated.
In these situations you will be aware that the
power management 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
syst
em*.
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 alternator 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.

The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.
Additional information about vehicles with
Adaptive Cruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again. Note
● In v ehic
les with an automatic gearbox, you
can control whether the engine should switch
off or not by reducing or increasing the brake
force applied. While the vehicle remains stop-
ped, the engine will not stop if the brake ped-
al is slightly pressed, in traffic jams with fre-
quent stopping and starting for example. As soon as strong pressure is applied to the
brak
e ped
al, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes

The engine does not switch off
Before the stopping phase, the system veri-
fies whether certain conditions are met. The
engine does not switch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required t
emperature for the Start-Stop
