If you drive at speeds above 40 mph (60 km/h) and lane markings are detected, symbol : is highlighted. Lane Keeping Assist is ready for use.
When Standard is selected, no warning vibration occurs if: Ryou switch on the turn signals. In this event, the warnings are suppressed for a certain period of time.
Ra driving safety system intervenes, such as
ABS, BAS or ESP®.
When Adaptive is selected, no warning vibration occurs if: Ryou switch on the turn signals. In this event, the warnings are suppressed for a certain period of time.
Ra driving safety system intervenes, e.g.
ABS, BAS or ESP®.
Ryou accelerate hard, e.g. kickdown. Ryou brake hard. Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend. In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognizes certain conditions and warns you accordingly. The warning vibration occurs earlier if: Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a
freeway.
Rthe system recognizes solid lane markings. The warning vibration occurs later if: Rthe road has narrow lanes. Ryou cut the corner on a bend.

Useful information
i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.
i Read the information on qualified specialist workshops: (Y page 24).
Important safety notes
G WARNING If you operate information systems and communication equipment integrated in the vehicle while driving, you will be distracted from traffic conditions. You could also lose control of the vehicle. There is a risk of an accident. Only operate the equipment when the traffic situation permits. If you are not sure that this is possible, park the vehicle paying attention to traffic conditions and operate the equipment when the vehicle is stationary. G WARNING If the instrument cluster has failed or malfunctioned, you may not recognize function restrictions in systems relevant to safety. The operating safety of your vehicle may be impaired. There is a risk of an accident. Drive on carefully. Have the vehicle checked at a qualified specialist workshop immediately.
You must observe the legal requirements for the country in which you are currently driving when operating the on-board computer. The on-board computer only shows messages or warnings from certain systems in the
multifunction display. You should therefore make sure your vehicle is operating safely at all times. Otherwise, a vehicle that is not operating safely may cause an accident. For an overview, see the instrument panel illustration (Y page 29).
Displays and operation Instrument cluster lighting The lighting in the instrument cluster, in the displays and the controls in the vehicle interior can be adjusted using the brightness control knob. The brightness control knob is located on the bottom left of the instrument cluster (Y page 29). X Turn the brightness control knob clockwise
or counter-clockwise. If the light switch is set to Ã, T or L, the brightness is dependent upon the brightness of the ambient light.
i The light sensor in the instrument cluster
automatically controls the brightness of the multifunction display. In daylight, the displays in the instrument cluster are not illuminated.
Coolant temperature display G WARNING Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.
Displays and operation 187
! A display message is shown if the coolant
temperature is too high. If the coolant temperature is over 248 ‡(120 †), do not continue driving. The engine will otherwise be damaged.
The coolant temperature gage is in the instrument cluster on the right-hand side. Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 248 ‡ (120 †).
Tachometer ! Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer indicates the engine's overrevving range. The fuel supply is interrupted to protect the engine when the red band is reached.
Outside temperature display You should pay special attention to road conditions when temperatures are around freezing point. The outside temperature display is in the multifunction display. Changes in the outside temperature are displayed after a short delay.
Speedometer with segments The segments in the speedometer indicate which speed range is available. RCruise control activated (Y page 157): The segments light up from the stored speed to the maximum speed.
RDISTRONIC PLUS activated (Y page 159):
One or two segments in the set speed range light up.
RDISTRONIC PLUS detects a vehicle in front:
The segments between the speed of the vehicle in front and the stored speed light up.

Possible causes/consequences and M Solutions ABS (Anti-lock Braking System), ESP® (Electronic Stability Program), BAS (Brake Assist), the HOLD function and hill start assist are temporarily unavailable. COLLISION PREVENTION ASSIST may also have failed. In addition, the ÷, å and ! warning lamps light up in the instrument cluster. ATTENTION ASSIST is deactivated. Possible causes are: RSelf-diagnosis is not yet complete. RThe on-board voltage may be insufficient. G WARNING The brake system continues to function normally, but without the functions listed above.
