of the controls are identical.
WARNING■ The activation of the lights should only be undertaken in accordance with
national legal requirements.■
The driver is always responsible for the correct settings and use of the
lights.
■
Never drive with only the side lights on! The side lights are not bright
enough to light up the road sufficiently in front of you or to be seen by oth-
er oncoming traffic. Therefore always switch on the low beam when it is
dark or if visibility is poor.
Note
■ The instruments are also illuminated when the side light or low beam light is
switched on.■
The headlights may mist up temporarily. When the driving lights are switched
on, the light outlet surfaces are free from mist after a short period, although
the headlight lenses may still be misted up in the peripheral areas. This mist
has no influence on the life of the lighting system.

Driving abroad
Read and observe
on page 48 first.
The low beam is set asymmetrically. It illuminates the side of the road on
which the vehicle is being driven to a greater extent.
When driving in countries with opposing traffic system (traffic on the left/
right), asymmetric headlight adjustment can dazzle oncoming traffic. In order
to avoid this, the headlights must be adjusted at a specialist garage.
Note
You can find out more information on adjusting the headlights at a specialist
garage.

51Lights and visibility

Avoid full throttle and high speeds
Fuel consumption will be halved if you drive at only three-quarters of the pos-
sible top speed of your vehicle.
Reducing idling
When the engine is switched off, such as when waiting in a traffic jam, the fuel economy is already greater after 30 - 40 s than the fuel quantity which is re-
quired for engine re-start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 118.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 1 l/100 km. At a speed of
100-120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Electrical consumers (e.g. seat heating, air conditioning and the like) only turn
on for as long as necessary.
Driving through water and driving off of made-up roads
Introduction
This chapter contains information on the following subjects:
Driving through water
83
Driving off paved roads
84WARNINGImmediately after driving through water, mud, slush and the like, braking
effectiveness will be temporarily impaired » page 78, Information on brak-
ing . For this reason, sudden and violent braking manoeuvres are to be
avoided - there is a risk of accident!Driving through waterFig. 83
Maximum permissible water lev-
el when driving through water
Read and observe on page 83 first.
The following instructions must be observed if vehicle damage is to be avoided when driving through water (e.g. flooded roads).
›
Therefore determine the depth of the water before driving through bodies of
water.
The water level must not reach above the web of the lower beam » Fig. 83.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle, which can
cause water to penetrate into the engine's air induction system or other parts
of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ Should water penetrate into the intake system of the engine, there is a
threat of serious damage being incurred by the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmission can be severely damaged.
■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through the body of water.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.
83Starting-off and Driving

The system is ready to intervene automatically in the following conditions.The engine is running.
The system is activated.
The travel speed is about 5-30 km/h.
The field of view of the laser sensor is not impaired.
If the system triggers automatic braking, the indicator symbol flashes
in the
display of the instrument cluster quickly.
Automatic braking interventions by the emergency brake function can be ter-
minated by pressing the clutch or the accelerator or by moving the steering
wheel.
The system can, for example, be affected in the following situations or not
be available.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
› Driving around “sharp” bends.
› When fully pressing down the accelerator pedal.
› When the laser sensor is dirty or obscured.
› When the vehicles are very dirty and have a low level of reflection.
If the system is not available or there is a system malfunction, the indicator
symbol flashes
slowly in the display of the instrument cluster.WARNING■
The windscreen may be neither blocked nor covered with dirt in the area
of the laser sensor. This can lead to impaired function of the sensor - risk of
accidents!WARNINGThe laser beam from the laser sensor can cause serious eye injuries. The la-
ser beam is not visible to the human eye.■
Never use optical devices, e.g. a range-finder camera or magnifying glass
to look into the laser sensor.
■
The laser beam can also be active when the system is disabled or is not
available.
CAUTION■ Remove the snow from the windscreen in the area of the laser sensor with a
hand brush and the ice with a solvent-free de-icing spray.■
If the laser sensor range on the windscreen has scratches, cracks, etc, re-
place the windscreen. Only use windscreens approved by the manufacturer.
■
When replacing the windscreen wiper blades, only use windscreen wiper
blades approved by the manufacturer.
Note
If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.
