Changing up a gear in time reduces fuel con-
sumption and noi se. Rev counter
The rev counter indicates the number of en-
gine rev
o

lutions per minute ››› Fig. 122 1 .
Tog ether w
ith the gear-change indicator, the
rev counter offers you the possibility of using
the engine of your vehicle at a suitable
speed.
The start of the red zone on the dial indicates
the maximum engine speed which may be
used briefly when the engine is warm and af-
ter it has been run in properly. Before reach-
ing this range, you should change to a higher
gear for vehicles with a manual gearbox or for
automatic gearboxes put the selector lever in
“D” or take your foot off the accelerator ped-
al.
We recommend that you avoid high revs and
that you follow the recommendations on the
gear-change indicator. Consult the additional
information in ›››
 page 42, Gear-change
indicator. CAUTION
Never allow the rev counter needle
›› ›

Fig. 122 1 to go into the red zone on the scale for more than a very brief period, other-

Fuel - Natural Gas level 3 Valid in vehicles equipped with natural gas engine
(GNC)
Fig. 126
Instrument panel: Natural gas gauge The gauges
››
› Fig. 126 and ››› Fig. 125 only
work when the ignition is on. When the dis-
play reaches the reserve mark, the lower LED
lights up in red and the control lamp  ap-
pears. When the fuel level is very low, the
lower diode flashes in red.
● The green warning lamp  ›››
Fig. 126 1 lights up when the vehicle is running in natu-
r
al
g
as operating mode.
● The green warning lamp  1 turns off
when the n at
ur

al gas is exhausted. The en-
gine changes to operate with petrol.
● The yellow control lamp  lights up when
the re
serve level has been reached. Things to note
If the v

ehicle is left parked for a long time im-
mediately after refuelling, the natural gas lev-
el indicator may not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af-
ter a cooling phase just after refuelling.
Control lamps
Warning and c
ontrol lamps Read the additional information carefully
› ›
›

 page 47.
The control and warning lamps are indicators
of warnings, ››› , faults
››
› or certain func-
tion s.
Some c

ontrol and warning lamps come
on when the ignition is switched on, and
switch off when the engine starts running, or
while driving.
Depending on the model, additional text
messages may be viewed on the instrument
panel display. These may be purely informa-
tive or they may be advising of the need for
action ›››
page 114, Instruments.
Depending upon the equipment fitted in the
vehicle, instead of a warning lamp, some- times a symbol may be displayed on the in-
strument p

anel.
When certain control and warning lamps are
lit, an audible warning is also heard. WARNING
If the warning lamps and messages are ignor-
ed, the v ehic

le may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps or text
mess
ages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure th
at there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and al
low it to cool.
● In any vehicle, the engine compartment is a
hazar
dous area and could cause severe inju-
ries ››› page 270. CAUTION
Failure to heed the control lamps and text
mes s

ages when they appear may result in
faults in the vehicle. 119

Description Read the additional information carefully
›› ›

 page 15
The vehicle can be locked and unlocked via
the central locking system. There are several
methods, depending on the vehicle equip-
ment:
● key with remote control ››
›

page 127 ,
● lock on driver door (emergency opening
›››
 page 15) or
● interior central locking switch ›››

page 128.
Unlocking one side of the vehicle only
When you lock the vehicle with the key, the
doors and the rear lid are locked. When you
open the door, you can either unlock only the
driver door, or all the vehicle doors. To select
the required option, use Easy Connect*
››› page 128.
Auto Lock*
The Auto Lock function locks the doors and
the rear lid when the vehicle exceeds a speed
of about 15 km/h (9 mph). The vehicle is unlocked again when the igni-
tion key i

s removed. Alternatively, the vehicle
can also be unlocked via the central locking
switch or by pulling one of the inside door
handles. The Auto Lock function can be
switched on and off on the sound system or
on the Easy Connect* system ››› page 128.
In the event of an accident in which the air-
bags inflate, the doors will be automatically
unlocked to facilitate access and assistance.
Anti-theft alarm system*
If the anti-theft alarm system senses interfer-
ence with the vehicle it triggers an audible
and visible alarm.
The anti-theft alarm system is automatically
switched on when locking the vehicle. It
switches off when the vehicle is unlocked
from a distance.
When the driver door is unlocked with the
key, you should switch on the ignition within
15 seconds. Otherwise the alarm will be trig-
gered. On some export versions, the alarm is
triggered immediately when you open a door.
To deactivate the alarm, press the  button
on the remote control key, or switch on the
ignition. After a certain time, the alarm will
automatically switch off.
Switch off the vehicle interior monitoring and
tow-away protection if you wish to prevent the alarm from being triggered accidentally
››› page 135.
Turn signals
The turn signals will flash twice when the ve-
hicle is unlocked and once when the vehicle
is locked.
If it does not flash, this indicates that one of
the doors, the rear lid or the bonnet is not
closed correctly.
Accidental lock-out
The central locking system prevents you from
being locked out of the vehicle in the follow-
ing situations: ● If the driver door is open, the vehicle can-
not be lock
ed with the central locking switch
››› page 128.
Lock the vehicle with the remote control key,
when all the doors and the rear lid have been
closed. This prevents the accidental locking
of the vehicle. WARNING
Do not leave anyone (especially children) in
the v ehic

le if it is locked from the outside and
the anti-theft security system* is enabled, as
the doors and windows cannot then be
opened from the inside. Locked doors could
delay assistance in an emergency, potentially
putting lives at risk. » 125

Opening and closing
Childproof lock 3 Applies to vehicles with 5 doors:
Fig. 139
Childproof lock on the left hand side
door . The childproof lock prevents the rear doors
fr
om bein
g opened fr
om the inside. This sys-
tem prevents minors from opening a door ac-
cidentally while the vehicle is running.
This function is independent of the vehicle
electronic opening and locking systems. It
only affects rear doors. It can only be activa-
ted and deactivated manually, as described
below:
Activating the childproof lock
– Unlock the vehicle and open the door in
which y

ou wish to activate the childproof
lock.
– With the door open, rotate the groove in
the door usin

g the ignition key, clockwise
for the left hand side doors ››› Fig. 139 and anti-clockwise for the right hand side
doors.
De

– Unlock the vehicle and open the door
whose chi

ldproof lock you want to deacti-
vate.
– With the door open, rotate the groove in
the door usin

g the ignition key, anti-clock-
wise for the left hand side doors ››› Fig. 139
and clockwise for the right hand side
doors.
Once the childproof lock is activated, the
door can only be opened from the outside.
The childproof lock can be activated or deac-
tivated by inserting the key in the groove
when the door is open, as described above.
Anti-theft alarm system* Des
cription The anti-theft alarm makes it more difficult to
br
e
ak

into the vehicle or steal it.
The anti-theft alarm is automatically turned
on when the vehicle is locked with the key.
● The turn signal light will flash twice on
opening and deactiv
ating the alarm. ●
The turn sign
al light will flash once on clos-
ing and activating the alarm.
When does the system trigger an alarm?
The anti-theft alarm siren will be triggered for
about 30 seconds accompanied by sound
and optical (flashing) warning signals and
will be repeated about ten times when the
vehicle is locked and the following unauthor-
ised actions are attempted:
● Opening a door that is mechanically un-
locked u
sing the vehicle key without switch-
ing on the ignition in the next 15 seconds (in
certain markets, such as the Netherlands,
there is no 15 second waiting time and the
alarm is activated immediately on opening
the door).
● A door is opened.
● The bonnet is opened.
● The rear lid is opened.
● When the ignition is switched on with a
non-authorised k
ey.
● When the vehicle battery is disconnected.
● Movement inside the vehicle (in vehicles
with interior monit
oring ››› page 135).
● When the vehicle is towed (in vehicles with
anti-tow sy
stem ››› page 135).
● When the vehicle is raised (in vehicles with
anti-to w sy

Safety

Operation
In norm al mode
(D), the g
e arbox automatical-
ly selects the best gear ratio. This depends
on the engine load, the road speed and the
dynamic gear control programme (DCP).
Sport mode (S) must be selected for a sporty
driving style. This setting makes use of the
engine's maximum power output. When ac-
celerating the gear shifts will be noticeable.
Press the brake pedal to move the selector
lever from N to D/S when the vehicle is sta-
tionary or at speeds below 3 km/h (2 mph)
››› .
Under c er
t

ain circumstances (e.g. when driv-
ing in mountains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 193, in order to manually select gear
ratios to suit the driving conditions. WARNING
● Tak e c

are not to accidentally press the ac-
celerator pedal when the vehicle is stopped.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident.
● Never move the selector lever to R or P
when driving. F
ailure to follow this instruc-
tion could result in an accident.
● With selector lever in any position (except
P) the vehic
le must always be held with the
foot brake when the engine is running. This is
because an automatic gearbox still transmits power even at idling speed, and the vehicle
tend
s

to “creep”. The accelerator pedal must
on no account be pressed inadvertently when
a gear is engaged with the vehicle stationary.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident.
● While you are selecting a gear and the vehi-
cle i
s stopped with the engine running, do
not accelerate. Failure to follow this instruc-
tion could result in an accident.
● As a driver you should never leave your ve-
hicle if
the engine is running and a gear is en-
gaged. If you have to leave your vehicle while
the engine is running, you must apply the
handbrake and engage the parking lock (P).
● To avoid accidents, apply the handbrake
and put the sel
ector lever in position P before
opening the bonnet and working on the vehi-
cle with the engine running. Please always
observe the important safety warnings
››› page 270, Working in the engine compart-
ment. Note
● If the sel ect

or lever is moved accidentally
to N when driving, release the accelerator and
let the engine speed drop to idling before se-
lecting gear range D or S again.
● Should the power supply to the selector
lever be int
errupted in position P, the selector
lever will be locked. If this should happen the
manual release can be used ›››
