Tips for driving with DISTRONIC PLUS General notes Pay particular attention in the following traffic situations: RCornering, going into and coming out of a

bend

RVehicles traveling on a different line

The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late. Vehicles traveling on a different line

DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short.

186 Driving systems

Other vehicles changing lanes

example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Crossing vehicles

DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles

DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road, because of its narrow width. The distance to the vehicle in front will be too short. Obstructions and stationary vehicles

DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally.

HOLD function General notes The HOLD function can assist the driver in the following situations: Rwhen pulling away, especially on steep

slopes

Rwhen maneuvering on steep slopes Rwhen waiting in traffic The vehicle is kept stationary without the driver having to depress the brake pedal. The braking effect is canceled and the HOLD function deactivated when you depress the accelerator pedal to pull away.

Vehicle level Important safety notes G WARNING When the vehicle is being lowered, people could become trapped if their limbs are between the vehicle body and the wheels or underneath the vehicle. There is a risk of injury. Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches when the vehicle is being lowered.

The vehicle lowers when you press the button for selecting the suspension tuning or the AMG button. The vehicle also lowers if it is stationary. ! If Sport or Sport + suspension tuning has

been selected, the vehicle's ground clearance decreases. Make sure that no objects become trapped or that the vehicle does not become damaged, for example, on the curb.

i The vehicle level may change visibly at the

rear axle if you park the vehicle and the outside temperature changes. If the temperature drops, the vehicle level lowers; with an increase in temperature, the vehicle level rises.

Changing the rear axle ride height This function is only available for the CLS 63
AMG 4MATIC. The vehicle level at the rear axle depends on the selected suspension tuning and the vehicle speed. The vehicle level at the rear axle changes during the journey depending on the selected suspension tuning: RComfort: +0.4 in (+10 mm) RSport + and Sport: -0.6 in (-15 mm) When switching from Comfort to Sport or Sport +, the rear axle lowers by approximately 1.0 in (25 mm). When switching from Sport or Sport + to Comfort, the rear axle raises by approximately 1.0 in (25 mm). This level change also takes place when the vehicle is stationary. If you drive faster than 105 mph (170 km/h), the rear axle ride height is set to a medium level. This increases driving safety and reduces air resistance. If you then drive at speeds below 93 mph (150 km/h), the rear axle ride height is readjusted to the selected suspension tuning.

Load compensation The vehicle can compensate differences in the vehicle level by raising or lowering the rear axle. This is the case, for example, if people get out or if luggage is being loaded. Load compensation takes place if: Ra door or the trunk lid/tailgate is opened Rthe parked vehicle is unlocked For larger level changes, the engine must be running.

4MATIC (permanent four-wheel drive) If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor override the laws of physics. 4MATIC cannot take account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. If a drive wheel spins due to insufficient grip: ROnly depress the accelerator pedal as far

as necessary when pulling away.

RAccelerate less when driving. ! Never tow the vehicle with one axle

raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground.

i In wintry driving conditions, the maximum

effect of 4MATIC can only be achieved if you use winter tires (M+S tires), with snow chains if necessary.

4MATIC ensures that all four wheels are permanently driven. Together with ESP®, it improves the traction of your vehicle whenever a drive wheel spins due to insufficient grip.

PARKTRONIC Important safety notes PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is only an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. When maneuvering, parking or pulling out of a parking space, make sure that there are no persons, animals or objects in the area in which you are maneuvering. ! When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects. The sensors may not detect snow and other objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic car wash, the compressed-air brakes on a truck or a pneumatic drill could cause PARKTRONIC to malfunction. PARKTRONIC may not function correctly on uneven terrain.

PARKTRONIC is activated automatically when you: Rswitch on the ignition Rshift the transmission to position D, R or N Rrelease the parking brake PARKTRONIC is deactivated at speeds above 11 mph (18 km/h). It is reactivated at lower speeds. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper.

194 Driving systems

Range of the sensors General notes PARKTRONIC does not take objects into consideration that are: Rbelow the detection range, e.g. people,

animals or objects

Rabove the detection range, e.g.

overhanging loads, truck overhangs or loading ramps.

: Sensors in the front bumper, left-hand

specialist workshop.

The PARKTRONIC sensors are dirty or there is interference. X Clean the PARKTRONIC sensors (Y page 315). X Switch the ignition back on. The problem may be caused by an external source of radio or ultrasound waves. X See if PARKTRONIC functions in a different location.

Active Parking Assist General notes Active Parking Assist is an electronic parking aid with ultrasound. It measures the road on both sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering intervention can assist you during parking. You may also use PARKTRONIC (Y page 193).

Important safety notes Active Parking Assist is merely an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. Make sure that no persons, animals or objects are in the maneuvering range. When PARKTRONIC is switched off, Active Parking Assist is also unavailable.

G WARNING The vehicle swings out when parking and in doing so could cross into the opposite lane. This could result in a collision with another road user. There is a risk of an accident. Pay attention to other road users when parking. Stop the vehicle if necessary or cancel the Active Parking Assist parking procedure.

! If unavoidable, you should drive over

obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires.

Active Parking Assist may possibly indicate parking spaces which are not suitable for parking, for example: Rwhere parking or stopping is prohibited Rin front of driveways or entrances and exits Ron unsuitable surfaces

Driving systems

197

Parking tips: ROn narrow roads, drive as close to the

parking space as possible.

RParking spaces that are littered or

overgrown might be identified or measured incorrectly.

RParking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly.

RSnowfall or heavy rain may lead to a parking

space being measured inaccurately.

RPay attention to the PARKTRONIC

(Y page 195) warning messages during the parking procedure.

RYou can intervene in the steering procedure

to correct it at any time. Active Parking Assist will then be canceled.

RWhen transporting a load which protrudes

from your vehicle, you should not use Active Parking Assist.

RNever use Active Parking Assist when snow

chains are installed.

RMake sure that the tire pressures are

always correct. This has a direct influence on the parking characteristics of the vehicle.

Use Active Parking Assist for parking spaces: Rthat are parallel to the direction of travel Rthat are on straight roads, not bends Rthat are on the same level as the road, e.g.

not on the pavement

Detecting parking spaces Objects located above the height range of Active Parking Assist will not be detected when the parking space is measured. These are not taken into account when the parking procedure is calculated, e.g. overhanging loads, tail sections or loading ramps of goods vehicles. G WARNING If there are objects above the detection range, Active Parking Assist may turn prematurely.

You may cause a collision as a result. There is a risk of an accident. If there are objects above the detection range, stop and deactivate Active Parking Assist.

For further information on the detection range (Y page 194). Active Parking Assist does not support you with parking spaces parallel to the direction of travel if: Rthe parking space is on a curb Rthe parking space appears blocked to the

system, for example, by foliage or grass paving blocks

Rthe area that the vehicle needs to

maneuver is too small

Rthe parking space is bordered by an

obstacle, such as a tree, a post or a trailer

Example: detected parking space : Detected parking space on the left ; Parking symbol = Detected parking space on the right Active Parking Assist is switched on automatically when driving forwards. The system is operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the system independently locates and measures parking spaces on both sides of the vehicle. Active Parking Assist will only detect parking spaces: Rthat are parallel to the direction of travel Rthat are at least 59 in (1.5 m) wide Rthat are at least 51 in (1.3 m) longer than

your vehicle

When driving at speeds below 19 mph (30 km/h), you will see parking symbol as a

198 Driving systems

status indicator in the instrument cluster. When a parking space has been detected, an arrow towards the right or the left also appears. By default, Active Parking Assist only displays parking spaces on the front- passenger side. Parking spaces on the driver's side are displayed as soon as the turn signal on the driver's side is activated. When parking on the driver's side, this must remain switched on until you acknowledge the use of Active Parking Assist by pressing the a button on the multifunction steering wheel. i Take note that Active Parking Assist

cannot measure the size of parking spaces that are at right angles to the direction of travel. You must decide for yourself whether the vehicle will fit in the parking space.

A parking space is displayed while you are driving past it, and until you are approximately 50 ft (15 m) away from it.

Parking G WARNING Active Parking Assist merely aids you by intervening actively in the steering. If you do not brake there is a risk of an accident. Always apply the brakes yourself when maneuvering and parking.

ATTENTION ASSIST Important safety notes ATTENTION ASSIST is only an aid to the driver. It might not always recognize fatigue or increasing inattentiveness in time or fail to recognize them at all. The system is not a substitute for a well-rested and attentive driver.

General notes ATTENTION ASSIST helps you during long, monotonous journeys, such as on highways. It is active in the range between 50 mph (80 km/h) and 112 mph (180 km/h). If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests you take a break. ATTENTION ASSIST assesses your level of fatigue or lapses in concentration by taking the following criteria into account: Ryour personal driving style, e.g. steering

characteristics

Rjourney details, e.g. time of day and length

of journey

The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Rif the road condition is poor, e.g. if the

surface is uneven or if there are potholes

Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration

Rif you are predominantly driving slower than 50 mph (80 km/h) or faster than 112 mph (180 km/h)

Rif you are currently using COMAND or

making a telephone call with it

Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed

204 Driving systems

Warning and display messages in the multifunction display X Activate ATTENTION ASSIST using the on-

board computer (Y page 228). If ATTENTION ASSIST is active, you will be warned no sooner than 20 minutes after your journey has begun. You then hear an intermittent warning tone twice and the Attention Assist: Drowsiness detected message appears in the multifunction display.

X If necessary, take a break. X Press the a button to confirm the

message.

On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break, you will be warned again after 15 minutes at the earliest. The precondition for this is that ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration. When ATTENTION ASSIST is deactivated, the À symbol and OFF appear in the multifunction display in the assistance graphics display when the engine is running. ATTENTION ASSIST is reset when you continue your journey and starts assessing your tiredness again if: Ryou switch off the engine. Ryou take off your seat belt and open the

driver's door, e.g. for a change of drivers or to take a break.

Night View Assist Plus Important safety notes Night View Assist Plus is only an aid and is not a substitute for attentive driving. Do not rely on the Night View Assist Plus display. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Drive carefully and always adapt

your driving style to suit the prevailing road and traffic conditions. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to snow,

rain, fog or spray

Rthe windshield is dirty, fogged up or

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

Ron bends, on uphill gradients or downhill

gradients

Pedestrian recognition may be impaired or inoperative if: Rpedestrians are partially or entirely

obscured by objects, e.g. parked vehicles Rthe silhouette of the pedestrian in the Night

View Assist Plus display is incomplete or interrupted, e.g. by powerful light reflections

Rpedestrians do not contrast adequately

from the background

Rpedestrians are not in an upright position,

e.g. sitting, squatting or lying

In addition to the illumination provided by the normal headlamps, Night View Assist Plus uses infrared light to illuminate the road. Night View Assist Plus camera : picks up the infrared light and displays a monochrome image in COMAND. The image displayed in COMAND corresponds to a road lit up by high- beam headlamps. This enables you to see the road's course and any obstacles in good time. If pedestrian recognition is activated, pedestrians recognized by the system are

Driving systems

205

highlighted in the Night View Assist Plus display. Light from the headlamps of oncoming vehicles does not affect the Night View Assist Plus display in the multifunction display. This is also the case if you cannot switch on the high-beam headlamps due to oncoming traffic. i Infrared light is not visible to the human

eye and therefore does not glare. Night View Assist Plus can therefore remain switched on even if there is oncoming traffic.

Activating Night View Assist Plus Activation conditions You can only activate Night View Assist Plus if: Rthe SmartKey is in position 2 in the ignition

lock.

Rit is dark. Rthe light switch is in the à or L

position.

Rreverse gear has not been engaged. Activating Night View Assist Plus

X Make sure that COMAND is switched on. X Press button :.

The Night View Assist Plus display appears in the COMAND display.

You can read about how to adjust the brightness of the COMAND display in the COMAND operating instructions.

i The infrared headlamps only switch on

when the vehicle is being driven at speeds of approximately 6 mph (10 km/h). This means that you do not have the full visual range while the vehicle is stationary and cannot check whether Night View Assist Plus is working.

Pedestrian recognition

: Night View Assist Plus display ; Pedestrian recognized = Framing ? Symbol for active pedestrian recognition i Animals are not recognized by pedestrian

recognition.

Night View Assist Plus is able to recognize pedestrians by typical characteristics, e.g. a silhouette in the shape of a person. Pedestrian recognition is then switched on automatically: Rif Night View Assist Plus is activated Rif you are driving faster than approximately

6 mph (10 km/h)

Rthe surroundings are dark, e.g. when driving outside built-up areas without street lighting

If pedestrian recognition is active, symbol ? appears. If pedestrians are detected, they are highlighted with framing =. If the pedestrian recognition system has brought a pedestrian to your attention, look through the windshield to evaluate the situation. The actual distance to objects and

206 Driving systems

pedestrians cannot be gaged accurately by looking at a screen. It may be the case that objects are highlighted as well as pedestrians.

Fogged up or dirty windshield G WARNING Always remember that you must concentrate primarily on driving the vehicle. A driver's attention to the road must always be his/her primary focus when driving. For your safety and the safety of others: stop the vehicle before attempting to clean fogged up windows or the windshield area in front of the Night View Assist Plus camera. Please remember that when your vehicle is traveling at a speed of only 30 mph (approximately 50 km/h) it covers a distance of 44 ft (approximately 14 m) per second.

If the windshield in front of the camera is fogged up or dirty on the inside or outside, the Night View Assist Plus display is affected. X To defrost: check the automatic air

conditioning settings (Y page 140) and fold down the camera cover (Y page 316).

X To defrost the inside of the windshield: fold down the camera cover (Y page 316) and clean the windshield (Y page 314).

Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 207) and Lane Keeping Assist (Y page 209).

Blind Spot Assist General notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from a speed of approximately 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lanes, you will also receive a visual and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes.

For Blind Spot Assist to assist you, the radar sensor system must be operational. Important safety notes G WARNING Blind Spot Assist does not react to: Rvehicles overtaken too closely on the side,
