2011 Mercedes-benz CL Class Owners Manual

Rthe windshield is dirty, fogged up or

covered, for instance by a sticker, in the vicinity of the camera.

Rthe lane markings are worn away, dark or

covered up, e.g. by dirt or snow.

Rthe distance to the vehicle in front is too

small and the lane markings thus cannot be detected.

Rthe lane markings on the road are unclear,

e.g. near roadworks.

Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge.

Rthe road is narrow and winding. Active Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

Warning vibration in the steering wheel A warning can be given when a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds. 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.

No warning vibration occurs if: Ryou clearly and actively steer, brake, or

accelerate.

Ryou cut the corner on a sharp bend. Ra driving safety system intervenes, such as

ABS, BAS or ESP®.

Ryou switch on the turn signals. In this event, the warnings are suppressed for a certain period of time.

Lane-correcting brake application If you leave your lane, under certain circumstances the vehicle will brake briefly on one side. This is designed to help you bring the vehicle back into the original lane. This function is available in the range between 40 mph and 120 mph (60 km/h and 200 km/h). A lane-correcting brake application can only be made after driving over a solid, recognizable lane marking. Before this, a warning must be emitted by means of intermittent vibration in the steering wheel. In addition, a lane with lane markings on both sides must be recognized. The brake application also slightly reduces driving speed. If a lane-correcting brake application occurs, the following message appears in the multifunction display:

i A further lane-correcting brake

application can only occur after your vehicle has returned to the original lane. G Warning Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the lane-

Active Lane Keeping Assist does not detect road and traffic conditions. An inappropriate brake application may be interrupted at any time if you: Rsteer slightly in the opposite direction Ruse a turn signal Rclearly brake or accelerate A lane-correcting brake application is interrupted automatically if: Ra driving safety system intervenes, such as

ESP®, PRE-SAFE® Brake or Active Blind Spot Assist.

Rlane markings can no longer be recognized. Activating Active Lane Keeping Assist

the on-board computer . Symbol : appears in the instrument cluster.

If you drive at speeds above 40 mph (60 km/h) and lane markings are detected, symbol : is displayed in green. Active Lane Keeping Assist is ready for use.

correcting brake application is not sufficient to bring your vehicle back to the original lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. Active Lane Keeping Assist does not detect road and traffic conditions. Always make sure that there is sufficient distance to the side for other traffic or obstacles. In rare cases, unclear markings or particular structures on the roadway can be recognized as solid lane markings. An inappropriate brake application, e.g. after intentionally driving over a solid lane marking, may be interrupted at any time by steering slightly in the opposite direction. Active Lane Keeping Assist cannot take account of weather conditions. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

No lane-correcting brake application occurs if: Ryou clearly and actively steer, brake, or

accelerate.

Ryou cut the corner on a sharp bend. Ryou switch on the turn signals. Ra driving safety system intervenes, such as

ESP®, PRE-SAFE® Brake or Active Blind Spot Assist.

Ryou have adopted a sporty driving style with

high cornering speeds or high rates of acceleration.

RESP® is deactivated. Rthe transmission is not in position D. Ra loss of tire pressure or a defective tire has

been detected and displayed.

Vehicle equipment

i This manual describes all the standard and optional equipment of your vehicle which was available at the time of purchase. Country-specific differences are possible. Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions.

Important safety notes

You will find an illustration of the instrument cluster in the "At a glance" section (Y page 32). G Warning A driver's attention to the road and traffic conditions must always be his/her primary focus when driving. For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely. Bear in mind that at a speed of just 30 mph (approximately 50 km/h ), your vehicle is covering a distance of 44 feet (approximately 14 m) every second. G Warning! No messages will be displayed if either the instrument cluster or the multifunction display is inoperative. As a result, you will not be able to see information about your driving conditions, such as Rspeed Routside temperature Rwarning/indicator lamps Rmalfunction/warning messages Rfailure of any systems Driving characteristics may be impaired.

If you must continue to drive, do so with added caution. Contact an authorized Mercedes- Benz Center as soon as possible. G Warning Malfunction and warning messages are only indicated for certain systems and are intentionally not very detailed. The malfunction and warning messages are simply a reminder with respect to the operation of certain systems. They do not replace the owner's and/or driver's responsibility to maintain the vehicle's operating safety. Have all required maintenance and safety checks performed on the vehicle. Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages.

Displays and operation Coolant temperature gauge 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.

The coolant temperature gauge is in the instrument cluster on the left-hand side. Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 248 ‡ (120 †). ! If the coolant temperature is too high a

display message is shown.

Displays and operation 329

If the coolant temperature rises above 248 ‡(120 †), do not drive any further as this could damage the engine.

Tachometer The red band in the tachometer indicates the engine's overrevving range. ! Do not drive in the overrevving range, as

this could damage the engine.

The fuel supply is interrupted to protect the engine when the red band is reached.

Outside temperature display The outside temperature display is in the multifunction display. G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

Changes in the outside temperature are displayed after a short delay.

Operating the on-board computer The on-board computer is activated as soon as you turn the key to position 2 in the ignition lock. You can control the multifunction display and the settings in the on-board computer using the buttons on the multifunction steering wheel.
