The intelligent Dynamic Road Sign Display technology cannot overcome the laws of 
physics, and functions only within the limits of the system. Do not let the extra 
convenience afforded by Dynamic Road Sign Display tempt you into taking any risks when 
driving, as this can cause accidents. The system is not a substitute for the full 
concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic 
conditions.
•Poor visibility, darkness, snow, rain and fog can cause road signs to be not displayed 
or be incorrectly displayed by the system.
•If the camera's field of view is dirty, covered or damaged, the function of the Dynamic 
Road Sign Display system may be impaired.
WARNING
Driving recommendations and traffic symbols displayed by the Dynamic Road Sign 
Display system may differ from the current traffic situation.
•Not all road signs can be recognised by the system and displayed correctly.
•Road signs and traffic regulations have priority over the recommendations and 
displays provided by the Dynamic Road Sign Display system.

Coolant temperature display
Fig. 21 In the instrument cluster: coolant temperature display (illustrationyf .
Driving when the fuel level is too low can lead to the vehicle coming to a standstill in 
traffic, potentially causing accidents and serious injuries.
•When the fuel level is too low, the fuel supply to the engine could be irregular, 
especially when driving up or down hills and inclines.
•The steering, all driver assist systems and brake support systems will not function if 
the engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
•Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel 
and breaking down.
WARNING
Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt 
fuel to enter the exhaust system. The catalytic converter or diesel particulate filter could be 
damaged as a result!

Front airbags
Fig. 44 Location and deployment zone of the driver front airbag.
Fig. 45 Location and deployment zone of the front passenger front airbag.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
In conjunction with the seat belts, the front airbag system gives the front occupants additional 
protection for the head and chest in the event of a severe frontal collision. Always keep as far away 
from the front airbag as possible ⇒ Sitting position. This allows the front airbags to inflate fully 
when triggered, thus providing maximum protection.
The front airbag for the driver is located in the steering wheel ⇒ Fig. 44 and the front airbag for the 
front passenger is located in the dash panel ⇒ Fig. 45. The airbag locations are identified by the 
text AIRBAG.
The areas inside the red lines are covered by the front airbags when deployed (deployment zoneyf   
You must never leave or attach any objects in these areas ⇒. Any factory-fitted accessories will 
not be struck if the driver and front passenger front airbags are deployed.
Once triggered, the airbag inflates at high speed.
•Always leave the deployment zones of the front airbags clear.
•Never attach any objects, such as drink or telephone holders, to the covers of the 
airbag modules or anywhere in the airbag module deployment zone.
•No other people, animals or objects may be carried between the occupants of the front 
seats and the airbag deployment zone. Ensure that children and passengers keep to 
this rule.
•Do not attach any objects, e.g. mobile navigation devices, to the windscreen above the 
front airbag on the front passenger side.
•Do not cover or stick anything on the steering wheel hub or the soft plastic surface of 
the airbag unit in the dash panel on the front passenger side, and do not modify them 
in any way.
DANGER
The front airbags are deployed in front of the steering wheel ⇒ Fig. 44 and dash panel 
⇒ Fig. 45.
•When driving, always hold the steering wheel with both hands on the outside of the 
ring at the 9 o'clock and 3 o'clock positions.
•Adjust the driver seat so that there is at least 25 cm between your breastbone and the 
hub of the steering wheel. Contact a qualified workshop if your physical build makes 
this impracticable.
•Adjust the front passenger seat so that the distance between the passenger and the 
dash panel is as large as possible.
WARNING 

The 12-volt vehicle battery will discharge if the hazard warning lights are left on over a long 
period of time – even when the ignition is switched off.
Depending on the vehicle equipment, the brake lights flash rapidly if you brake sharply or 
initiate full braking at a speed of more than 80 km/h (50 mphyf   7 K L V  L V  D  S D U W L F X O D U O \  H I I H F W L Y H  Z D \  R I

WARNING 

Seats and head restraints
Front seats
 Introduction
This chapter contains information on the followingsubjects:
⇒ Mechanically adjusting the front seat
⇒ Electrically adjusting the front seat
⇒ Folding the front passenger seat backrest forwards
The following section describes the options for adjusting the front seats. Always ensure that the 
correct sitting position is adjusted ⇒ Sitting position.
Incorrect use of the steering column position adjustment and incorrect adjustment of the 
steering wheel can cause serious or fatal injuries.
•After adjusting the steering column, always move lever ⇒ Fig. 77① up so that it 
engages securely. This prevents the steering column from moving spontaneously 
while the vehicle is in motion.
•Never adjust the steering wheel when the vehicle is in motion. If you determine that a 
readjustment is necessary, stop the vehicle safely and adjust the steering wheel to the 
correct position.
•The steering wheel must always point towards the chest and not towards the face. This 
ensures that the driver front airbag provides maximum protection in the event of an 
accident.
•While driving, always keep both hands on the outside of the steering wheel at the 9 
o'clock and 3 o'clock positions⇒ Fig. 78. This reduces the risk of injury if the driver 
front airbag is triggered.
•Never hold the steering wheel at the 12 o'clock position, or in any other manner, e.g. on 
the hub of the steering wheel. If the driver front airbag is triggered, you could receive 
severe injuries to the arms, hands and head.
