Engine revolutions counter
The red zone of the rev counter scale ⇒page 10, fig. 2 indicates the range in
which the engine control unit begins to li mit the engine speed. The engine control
unit restricts the engine speed to the steady limit value.
Shift into the next higher gear or select the selector lever position D of the auto-
matic gearbox before reaching the red zone of the rev counter scale.
Avoid high engine speeds during the driving time and before the engine has been
warmed up to operating temperature ⇒page 187.
For the sake of the environment
Shifting up early helps yo u save fuel and reduce the operating noise of your
vehicle.
Speedometer
Warning against excessive speeds*
An acoustic warning signal will sound wh en the vehicle speed exceeds 120 kilome-
tres per hour. The acoustic warning signal will switch off again when the vehicle
speed goes below this speed limit.
Note
This function is only valid for some countries.
Coolant temperature gauge
The coolant temperature gauge ⇒page 10, fig. 2 operates only when the igni-
tion is switched on.
In order to avoid any damage to the engine , please pay attention to the following
notes regarding the temperature ranges: Cold range
If the pointer is in the left-hand area of
the scale it means that the engine has not
yet reached its operating temp erature. Avoid running at high engine speeds, at full
throttle and at severe engine loads.
The operating range
The engine has reached its operating temperature as soon as the pointer moves
into the mid-range of the scale. The pointe r may also move further to the right at
high engine loads and high outside temperatures. This is not critical provided the
warning symbol
in the instrument cluster does not flash.
If the symbol
in the instrument cluster flashes it means that either the coolant
temperature is too high or the coolant level is too low. Observe the guidelines
⇒ page 31, “Coolant temperature/ Coolant quantity ”.
WARNING
Pay attention to the warning notes ⇒page 209, “Working in the engine
compartment” before opening the bonn et and inspecting the coolant level.
Caution
Additional headlights and other attached co mponents in front of the fresh air inlet
impair the cooling efficiency of the coolant. There is then a risk of the engine over-
heating at high outside temper atures and high engine loads!
Fuel gauge
The fuel gauge ⇒page 10, fig. 2 only operates when the ignition is switched on.
The fuel tank has a capacity of ab out 60 litres. The warning symbol
in the instru-
ment cluster lights up when the pointer reaches the reserve marking. There are now
about 9 litres of fuel remaining in the tank. This symbol is a reminder for you, that
you must refuel .
The following will be displayed in the information display*: Please refuel! (Please refuel!)

Switching off the hazard warning light system is switched on will cause all of the
turn signal lights as well as both indicator lights to flash.
Further information about the turn signal system ⇒page 60.
Fog lights
The warning light comes on when the fog lights are operating ⇒page 57.
Main beam
The indicator light comes on when the main beam is selected or also when the
headlight flasher is operated.
Further information about the main beam ⇒page 60.
Low beam
The warning light comes on when low beam is selected ⇒page 53.
Rear fog light
The warning light comes on when the rear fog lights are operating ⇒ page 58.
Cruise control system*
The warning light lights up, when operating the speed regulating system.
Failure of the light bulbs
The warning light comes on if a light bulb is damaged:
•up to 2 seconds after the ignition is switched on;
•when switching on the defective light bulb.
The following text e.g will be displayed in the information display*: Check front right dipped beam!
The rear side lights and the licence plate lighting require several light bulbs. The
indicator light
only lights up if all light bulbs of the licence plate lighting or the
parking light (in one rear light unit) are defe ctive. Check regularly the function of the
light bulbs.
Adaptive headlights*
If the warning light flashes for 1 minute while driving or after switching on the
ignition and a warning signal sounds, a fault of the adaptive headlights is
confirmed.
Further information ⇒page 56.
Diesel particle filter* (diesel engine)
If the warning light comes on, this means that soot has accumulated in the
diesel particle filter because of the frequent short distances.
In order to clean the diesel particle filter, the vehicle should be driven at an even
speed of at least 60 km/h at engine speeds of 1 800 - 2 500 rpm for at least 15
minutes or until the warning light goes ou t with the 4th or 5th gear engaged (auto-
matic gearbox: position S) when the traffi c situation permits it. This increases the
exhaust temperature and the soot deposited in the diesel particle filter is burnt.
Always pay attention to the valid speed limits ⇒.
The warning light
goes out after the successful cleaning of the diesel particle
filter.
If the filter is not properly cleaned, the warning light
does not go out and the
warning light begins to flash. In the information display* appears Diesel-
particle Owner's manual . Afterwards the engine contro l unit shifts the engine into
the emergency mode, which only has a re duced power output. After switching the
ignition off and on again the warning light
comes on.

tion, the low beam is switched off automati cally and only the side lights come on.
On models fitted with right-hand steering the position of certain switches differs
from that shown in ⇒fig. 41 . The symbols which mark the switch positions are
identical, however.
WARNING
Never drive with side lights on - risk of accident! The side lights are not
bright enough to light up the road suffic iently in front of you or to be seen by
other oncoming traffic. In this case, always switch on the low beam when it
is dark or if visibility is poor.
Note
•An audible warning will sound if you wi thdraw the ignition key and open the
driver's door when the vehicle lights are still on.
•The acoustic warning signal is switched off over the door contact when the
driver's door is closed (ignition off). The vehicle can be parked with the side lights
on.
•If the car is parked for a lengthy period , we recommend switching off all lights,
or leaving only the parking lights switched on.
•The switching on of the described lights should only be undertaken in accord-
ance with the legal requirements.
•If a fault occurs in the light switch , the low beam comes on automatically
•In the event of cool or humid weather co nditions, the headlights can be misted
up from inside.
−The temperature difference between interior and external area of the head-
light lenses is decisive.
− When the driving lights are switched on , the light outlet surfaces are free
from mist after a short period. The headlight lenses can possibly mist up at the
border areas.

•You can change the illumination period for the Coming Home Function by
means of the information display*.
Leaving Home Function
This function makes it possible to switch on the lights when approaching
the vehicle.
Switching on Leaving Home Function
– Unlock the vehicle with the radio remote control - the lights come on.
Depending on equipment fitted the function Leaving Home switches on the
following lights:
•Parking lights,
•Low beam,
•Entry lighting in the exterior mirrors,
•Licence plate light.
Leaving Home Function
The function Leaving Home is controlled wi th the light sensor in the mount of the
interior rear mirror. If the light intensity is higher than the set value of the light
sensor, the Leaving Home Func tion is not switched on after unlocking the vehicle
with the radio remote control.
After unlocking the vehicle with the radio re mote control, the lights come on for 30
seconds. The Leaving Home Function is al so switched off after the ignition is
switched on and after locking the vehicle.
If no door is opened within 30 seconds, the lights go out and the vehicle is locked
automatically.
Note
•If the Leaving Home Function is switched on constantly, the battery will be
heavily discharged particularly in short-haul traffic.
•The switching on of the described lights should only be undertaken in accord-
ance with the legal requirements.
•You can change the illumination period for the Leaving Home Function by
means of the information display*.
Adaptive head lights (AHL)*
Switch on Adaptive headlights (AHL)*
– Turn the light switch ⇒page 54, fig. 42 into position
.
The outer illumination switches on if:
•the light sensor recognizes the low light intensity,
•no reverse gear is engaged,
•the operation “tourist light” is not switched on.
The light sensor switches on the full ou ter illumination at low light intensity,
System AHL* makes it possible to change the length and width of illumination of
the headlight. The length and width of illumination changes automatically in rela-
tion to the vehicle speed and the use of the windscreen wiper.
System AHL* operates in the following modes.
Mode out of town
The mode “out of town” is a basic mode. The dispersion of the cone of light in front
of the vehicle is similar to the low beam. Th e mode is active if none of the following
modes are active.
Mode rain
In the mode “rain” the dispersion of the cone of light in front of the vehicle is wider
and the width of illumination is shorter, so that during bad weather (rain) the
dazzling of the oncoming drivers can be re duced. The mode is activated at speeds
of 15 - 70 km/h and if the windscreen wi pers continuously operate for a period of
time longer than 2 minutes. The mode is deactivated when dropping below or
exceeding the set speed limit or if the windscreen wipers have been switched off for
a period of time longer than 8 minutes.

Headlamp range adjustment*
Once the low beam is switched on you can then adapt the range of
the headlights to the load of the vehicle.
– Turn the control dial ⇒fig. 45 until you have adjusted the low beam
so that oncoming traffic is not dazzled.
Settings
The positions correspond approximat ely to the following vehicle loads:
Front seats occupied, luggage compartment empty.
All seats occupied, lugg age compartment empty.
All seats occupied, lugg age compartment laden.
Driver seat occupied, luggage compartment laden.
Caution
Set the headlight beam adjustment in such a way as to avoid dazzling oncoming
traffic.
Note
The Bi-Xenon bulbs* adapt automatically to the load and driving state of the vehicle
(e.g. speed, accelerating, braking) when the ignition is switched on and when driving. Vehicles which are not equipped
with Bi-Xenon bulbs* do not have a
manual headlight rang e adjustment control.
Switch for hazard warning lights
–Press switch ⇒ fig. 46 to switch the hazard warning light system on
or off.
All the turn signal lights on the vehicle flash at the same time when the hazard
warning light system is switched on. The indicator light for the turn signals and the
indicator light in the switch also flash at the same time. You can also switch on the
hazard warning light system if the ignition is switched off.
The hazard warning light system is switched on automatically if an airbag is
deployed in the event of an accident.
Please comply with any legal requirements when using the hazard warning light
system.
Note
Switch on the hazard warning light system if, for example:
•you encounter traffic congestion,
•your vehicle breaks down or an emergency situation occurs.

•If there is an obstacle on the windscre en, the wiper will try to push away the
obstacle. If the obstacle cont inues to block the wiper, the wiper stops after 5 cycles,
in order to avoid a damage to the wiper. Remove the obstacle and and switch on
the wiper again.
Headlight cleaning system*
The headlights are being cleaned after the windscreen has been sprayed for the first
time and fifth time, the low beam or ma in beam are switched on and the wind-
screen wiper lever was he ld in the position ⇒page 65, fig. 58 for about 1
second.
The headlight washer nozzles are moved forward out of the bumper by the water
pressure for cleaning the headlights.
You should remove stubborn dirt (such as insect residues) from the headlight
lenses at regular intervals, for example when refuelling. Please refer to the following
guidelines.
You should remove any snow from the fixt ures of the washer nozzles and clear ice
in winter with a de-icing spray in order to ensure proper operation of the cleaning
system.
Replacing wiper blades fo r the windscreen wipers
One cannot fold out the wiper arms in the rest position from the wind-
screen. Before replacing the wiper arms you must put them into the
service position.
Service position for changing wiper blades
– Close the bonnet.
– Switch the ignition on and then again off.
– Then press the windscreen wiper lever in the position ⇒page 65,
fig. 58 within 10 seconds - the wiper arms move into the service posi-
tion.
Taking off the wiper blade
– Fold windscreen wiper arm away from the windscreen.
– Press the locking button, in order to unlock the wiper blade and pull off in the direction of arrow ⇒fig. 59 .
Attaching a wiper blade
– Push the wiper blade until it locks up to the stop.
– Check whether the wiper blade is correctly attached.
– Fold the windscreen wiper arm back onto the windscreen.
The wiper arms return to the rest position after switching on the ignition and
changing the position of the window wiper lever or when driving at a speed greater
than 6 km/h.
Wiper blades in proper condition are esse ntial to obtain good visibility. Wiper
blades should not be allowed to become dirtied by dust, insect remains and
preserving wax.
Juddering or smearing of the wiper blades could then be due to wax residues left
on the windscreen by vehicle washing in automatic vehicle wash systems. It is
therefore important to degrease the lips of the wiper blades after every pass
through an automatic vehicle wash system .
