lock only engages with the vehicle sta-
tionary and at speeds of up to 5 km/h
(3 mph). At speeds of over 5 km/h (3 mph)
the lever lock is automatically deactivated in
position N.
The selector lever lock is not engaged if the
selector lever is moved quickly through posi-
tion N (e.g. when shifting from R to D). This
makes it possible, for instance, to rock the
vehicle “backwards and forwards” if it is
stuck. The selector lever lock engages auto-
matically if the brake pedal is not depressed
and the lever is in position N for more than
about two seconds.
Interlock button
The interlock button on the selector lever
handle prevents the driver from inadvertently
engaging certain gears. Press the button in
to disengage the selector lever lock. The se-
lector lever positions in which the interlock
button has to be pressed are shown in the il-
lustration, highlighted in colour ››› Fig. 198.
Safety interlock for ignition key
If the vehicle does not have electronic brak-
ing, and depending on the country, once the
ignition has been turned off, the key may be
removed only if the gear selector is in posi- tion P. While the key is not in the ignition, the
selector l
ever is locked in position P. Note
● If the sel ect

or lever lock does not engage,
there is a fault. The transmission is interrup-
ted to prevent the vehicle from accidentally
moving. Follow the procedure below in order
for the selector lever lock to engage again:
–With a 6-speed gearbox: press the brake
pedal and release it again.
– With a 7-speed gearbox: press the brake
pedal. Move the selector lever to posi-
tion P or N and subsequently engage a
gear.
● Despite a gear being engaged, the vehicle
does not
move forwards or back. Proceed to
the next mode:
– When the vehicle does not move in the
required direction, the system may not
have the gear range correctly engaged.
Press the brake pedal and engage the
gear range again.
– If the vehicle still does not move in the
required direction, there is a system mal-
function. Seek specialist assistance and
have the system checked. Engaging gears with the triptonic

o a norm
al level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 280 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that 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 he
ating*.
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 batt
er

y 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-
agnosis 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. »

Shor
t
trip

s, city traffic and low temperatures
all place 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 s

tarting 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 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 electric
al 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.

Introduction WARNING
● Bec au

se of the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard! 202

Driving
●
Do not ap p
ly wax underneath the vehicle
around the area of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  r
e-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
3 App
lies to vehicles with petrol engine
The
vehicle must only be used with unleaded
petrol, otherwise the catalytic converter will
be irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
Diesel particulate filter 3 App
lies to vehicles with diesel engine
The die
sel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may benoticed because the engine idle speed in-
cr
e

ases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The
rise in temperature causes the soot on the fil-
ter to burn. On completion of the cleaning
the warning lamp will switch off. If the warn-
ing lamp does not switch off, go immediately
to a specialised workshop to rectify the prob-
lem.
Engine management*  This warning lamp monitors the engine man-
ag
ement
sy

stem for petrol engines.
The warning lamp  (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Take the vehi- cle to a specialised workshop as soon as
poss

ible and have the engine checked.

ible. WARNING
● Ev en w

ith four-wheel drive, you should al-
ways adjust your speed to suit the condi-
tions. Do not let the extra safety features
tempt you into taking any risks when driving.
Risk of accident!
● The braking capability of your vehicle is
limited by
the tyres' grip. It is therefore no
different from a car without four-wheel drive.
So do not be tempted to drive too fast on firm
or slippery roads just because the vehicle
still has good acceleration in these condi-
tions. Risk of accident!
● On wet roads bear in mind that the front
wheels m
ay start to “aquaplane” and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as occurs with a front-wheel drive car.
For this reason you should always choose a
driving speed suitable for the road condi-
tions. Risk of accident! Driver assistance systems

● 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 remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-

Once connected, the Auto Hold function as-
sists the driver in keeping the vehicle station-
ary at repeated intervals or for a certain peri-
od of time with the engine running, for exam-
ple, when going up a slope, when stopped at
traffic lights or in heavy traffic with intermit-
tent stops.
When connected, the Auto Hold function au-
tomatically prevents the vehicle from rolling
when stationary without pressing the brake
pedal. After detecting that the vehicle is stationary
and the brake ped

al has been released, the

driver can lift their foot off the brake pedal.
When the driver touches the accelerator ped-
al or accelerates slightly to continue driving,
the Auto Hold function releases the brake.
The vehicle moves according to the slope of
the road.
If the vehicle is stationary and one of the con-
ditions required by the Auto Hold function is
impaired, it disconnects itself and the but-
ton's control light goes out ››› Fig. 202. The
