Driving tips General notes G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving.
ECO display The ECO display provides feedback on how economical your driving characteristics are. The ECO display assists you in achieving the most economical driving style for the selec- ted settings and prevailing conditions. Con- sumption can be significantly influenced by your driving style.
Example: ECO display The ECO display consists of three bars: RAcceleration RConstant RCoasting The percentage count is the mean value of the three bar values. The three bars and the mean value begin at the value of 50%. A higher per- centage count indicates a more economical driving style. The ECO display does not indicate the actual fuel consumption and a fixed percentage count in the ECO display does not indicate a fixed consumption figure.
Driving tips
165
In addition to driving style, the consumption is affected by many other factors, such as: Rload Rtyre pressure Rcold start Rchoice of route Rthe use of electrical consumers These factors are not included in the ECO dis- play. The evaluation of your driving style takes the following three categories into consideration: RAcceleration (evaluation of all accelera- tion processes): - The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration RConstant (assessment of driving behav- iour at all times): - The bar fills up: constant speed and
avoidance of unnecessary acceleration and deceleration
- The bar empties: fluctuations in speed RCoasting (assessment of all deceleration processes): - The bar fills up: anticipatory driving,
keeping your distance and early release of the accelerator. The vehicle can coast without use of the brakes
- The bar empties: frequent braking
i An economical driving style involves driv-
ing at a moderate engine speed. To achieve a higher value in the categories Acceleration and Constant: Robserve the gearshift recommendation. Rdrive the vehicle in drive program E (vehi-
cles with automatic transmission). i On long journeys at a constant speed, e.g. on the motorway, only the bar for Con‐ stant will change. i The ECO display summarises the driving characteristics from the start of the journey to its completion. Therefore, there are
166 Driving tips
dynamic changes in the bars at the start of a journey. During a prolonged driving time, these changes are smaller. For more dynamic changes, perform a manual reset. For further information on the ECO display, see (Y page 212).
Braking Important safety notes G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. This increases the risk of skidding and having an accident. Do not shift down for additional engine brak- ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle and when towing a trailer. For vehicles with auto- matic transmission, you need to have selec- ted manual drive program M(Y page 156). i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS- TRONIC PLUS.
This will use the braking effect of the engine, so less braking will be required to prevent the vehicle from gaining speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. i Briefly depressing the accelerator pedal
on downhill gradients while the manual drive program M is temporarily activated (vehicles with automatic transmission): the automatic transmission may switch back to the last active automatic drive program E or S. The automatic transmission may shift
to a higher gear. This can reduce the engine's braking effect.
Heavy and light loads G WARNING The braking system can overheat if you leave your foot on the brake pedal while driving. This increases the braking distance and could even cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Do not simultaneously depress both the brake pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to the brake pads.
If heavy demands are made on the brakes, do not park the vehicle immediately. Drive on for a short while. This allows the airflow to cool the brakes more quickly. If the brakes have been used only moderately, you should occasionally test their effective- ness. To do this, brake more firmly from a higher speed, paying attention to traffic con- ditions. This improves the grip of the brakes.
Wet road surfaces If you have driven for a long time in heavy rain without braking, there may be a delayed reac- tion from the brakes when braking for the first time. This may also occur after a car wash or after driving through deep water. You have to depress the brake pedal more firmly. Maintain a greater distance from the vehicle in front. After driving on a wet road or having the vehi- cle washed, brake firmly while paying atten- tion to the traffic conditions. This will warm up the brake discs, thereby drying them more quickly and protecting them against corro- sion.
Driving tips
167
Limited braking performance on salt- treated roads If you drive on salted roads, a layer of salt residue may form on the brake discs and brake pads. This can result in a significantly longer braking distance. RBrake occasionally to remove any possible
salt residue. Make sure that you do not endanger other road users when doing so. RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
New brake pads/linings New and replaced brake pads and discs only reach their optimum braking effect after sev- eral hundred kilometres of driving. Compen- sate for this by applying greater force to the brake pedal. For safety reasons, Mercedes-Benz recom- mends that you only have brake pads/linings fitted to your vehicle which have been approved for Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake pads/linings which have not been approved for Mercedes-Benz vehicles or which are not of an equivalent quality could affect your vehicle's operating safety.
Driving on wet roads Aquaplaning If water has accumulated to a certain depth on the road surface, there is a danger of aqua- planing occurring, even if: Ryou are driving at low speeds Rthe tyres have adequate tread depth For this reason, do not drive in tyre ruts and brake carefully.
Driving on flooded roads ! Bear in mind that vehicles travelling in front or in the opposite direction create waves. This may cause the maximum per- missible water depth to be exceeded. These notes must be observed under all circumstances. You could otherwise dam- age the engine, the electronics or the trans- mission.
If you have to drive on stretches of road on which water has collected, please bear in mind that: Rthe maximum permissible fording depth in
still water is 25 cm
Ryou should drive no faster than walking
pace
Winter driving General notes G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. This increases the risk of skidding and having an accident. Do not shift down for additional engine brak- ing on a slippery road surface. G DANGER If the exhaust pipe is blocked or adequate ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle becomes trapped in snow. There is a risk of fatal injury. If you leave the engine or the auxiliary heating running, make sure the exhaust pipe and area around the vehicle are clear of snow. To ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not facing into the wind.
168 Driving systems
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Winter operation" section (Y page 320).
Driving with summer tyres Observe the notes in the "Winter operation" section (Y page 320).
Slippery road surfaces G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. This increases the risk of skidding and having an accident. Do not shift down for additional engine brak- ing on a slippery road surface.
If the vehicle threatens to skid or cannot be stopped when moving at low speed: X Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip- pery road surfaces. Avoid sudden accelera- tion, steering and braking manoeuvres. The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Changes in the outside temperature are dis- played after a short delay. Indicated temperatures just above the freez- ing point do not guarantee that the road sur- face is free of ice. The road may still be icy, especially in wooded areas or on bridges. You should pay special attention to road condi- tions when temperatures are around freezing point. i For more information on driving with
snow chains, see (Y page 321).
Driving systems Cruise control Important safety notes If you fail to adapt your driving style, cruise control can neither reduce the risk of an acci- dent nor override the laws of physics. Cruise control cannot take into account road, weather or traffic conditions. Cruise control is only an aid. You are responsible for the dis- tance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in the lane. Do not use cruise control: Rin road and traffic conditions which do not
allow you to maintain a constant speed (e.g. in heavy traffic or on winding roads).
Ron smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose traction and the vehicle could then skid.
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow.
If there is a change of drivers, advise the new driver of the speed stored.
General notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. You must select a lower gear in good time on long and steep downhill gradients, especially if the vehicle is laden or towing a trailer. For vehi- cles with automatic transmission, you need to have selected manual drive program M(Y page 156). By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Use cruise control only if road and traffic con- ditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 30 km/h.

you shift into position N while driving. If cruise control is deactivated, you will hear a warning tone. You will see the Cruise control off message in the multifunction display for approximately five seconds. i The last speed stored is cleared when you
switch off the engine.
SPEEDTRONIC Important safety notes SPEEDTRONIC brakes automatically so that you do not exceed the set speed. On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must select shift range 1, 2 or 3 in good time. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If you need additional braking, depress the brake pedal repeatedly rather than continu- ously. If you fail to adapt your driving style, SPEED- TRONIC can neither reduce the risk of an accident nor override the laws of physics. SPEEDTRONIC cannot take into account road, weather or traffic conditions. SPEED- TRONIC 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 stay- ing in the lane. If there is a change of drivers, advise the new driver of the speed stored.
General notes You can set a variable or permanent limit speed: Rvariable for speed limits, e.g. in built-up

Shortly before the stored speed is reached, it appears in the multifunction display. Permanent SPEEDTRONIC remains active, even if variable SPEEDTRONIC is deactivated. You cannot exceed the stored limit speed, even if you depress the accelerator pedal beyond the pressure point (kickdown).
DISTRONIC PLUS Important safety notes G WARNING DISTRONIC PLUS does not react to: Rpeople or animals Rstationary obstacles on the road, e.g. stop-
ped or parked vehicles
Roncoming and crossing traffic As a result, DISTRONIC PLUS may neither give warnings nor intervene in such situations. There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake. G WARNING DISTRONIC PLUS cannot always clearly iden- tify other road users and complex traffic sit- uations. In such cases, DISTRONIC PLUS may: Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor intervene Raccelerate unexpectedly There is a risk of an accident. Continue to drive carefully and be ready to brake, in particular when warned to do so by DISTRONIC PLUS. G WARNING DISTRONIC PLUS brakes your vehicle with up to 40% of the maximum braking force. If this braking force is insufficient, DISTRONIC PLUS warns you visually and audibly. There is a risk of an accident.
In such cases, apply the brakes yourself and try to take evasive action.
! If DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automati- cally in certain situations. To prevent dam- age to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in the follow- ing or other similar situations: Rwhen towing the vehicle Rin the car wash
If you fail to adapt your driving style, DIS- TRONIC PLUS can neither reduce the risk of an accident nor override the laws of physics. DISTRONIC PLUS cannot take road and weather conditions or traffic conditions into account. DISTRONIC PLUS 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 the lane. Do not use DISTRONIC PLUS: Rin road and traffic conditions which do not
allow you to maintain a constant speed (e.g. in heavy traffic or on winding roads).
Ron smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose traction and the vehicle could then skid.
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow.
DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. In particular, the detection of obstacles can be impaired by: Rdirt on the sensors or anything else cover-
ing the sensors
Rsnow or heavy rain Rinterference by other radar sources Rthe possibility of strong radar reflections,
for example, in multi-storey car parks
If DISTRONIC PLUS no longer detects a vehi- cle in front, it may unexpectedly accelerate to the speed stored.
174 Driving systems
This speed can: Rbe too high for a filter lane or a slip road Rbe so high in the right lane that you pass
vehicles driving on the left
Rbe so high in the left lane that you pass
vehicles driving on the right
If there is a change of drivers, advise the new driver of the speed stored.
General notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the dis- tance to the vehicle detected in front. DIS- TRONIC PLUS brakes automatically so that the set speed is not exceeded. You must select a lower gear in good time on long and steep downhill gradients, especially if the vehicle is laden or towing a trailer. For this, you need to have selected manual drive program M(Y page 166). By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If a slower-moving vehicle is detected in front, DISTRONIC PLUS brakes your vehicle. It maintains the preset distance to the vehicle in front. If DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. Without your intervention, DIS- TRONIC PLUS cannot prevent a collision. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately to increase the distance to the vehicle driving in front, or take evasive action, provided it is safe to do so. The radar sensor system is switched off auto- matically in the vicinity of radio telescope facilities (Y page 350). For DISTRONIC PLUS to assist you when driv- ing, the radar sensor system must be: Ractivated (Y page 223) Roperational
i In some countries you must deactivate the radar sensor system (Y page 223). For further information about the radar sen- sor system; see (Y page 350).
DISTRONIC PLUS is automatically deactiva- ted if: Ryou are driving slower than 25 km/h and
there is no longer a vehicle in front or
Rthe vehicle ahead has not been detected If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control in the speed range between 30 km/h and 200 km/h. If a vehicle is driving in front of you, it operates in the speed range between 0 km/h and 200 km/h. Do not use DISTRONIC PLUS on roads with steep gradients.

Activating To activate while driving: you can only acti- vate DISTRONIC PLUS at speeds below 20 km/h if the vehicle in front is detected and shown in the multifunction display. If the vehi- cle in front is no longer detected and dis- played, DISTRONIC PLUS switches off and you will hear a tone. X Briefly pull the cruise control lever towards
you ? or press it up : or down A. DISTRONIC PLUS is activated.
X Press the cruise control lever repeatedly up : or down A until the desired speed is set.
X Remove your foot from the accelerator
pedal. Your vehicle adapts its speed to that of the vehicle in front, but only up to the desired stored speed.
When driving at speeds below 30 km/h, you can only activate DISTRONIC PLUS if the vehi- cle in front has been detected and is shown in the multifunction display. If the vehicle in front is no longer detected and displayed, DISTRONIC PLUS switches off and you will hear a tone. i If you do not fully release the accelerator pedal, the DISTRONIC PLUS inactive message appears in the multifunction dis- play. The set distance to a slower-moving vehicle in front will then not be maintained. You will be driving at the speed you deter- mine by the position of the accelerator pedal.
Displaying DISTRONIC PLUS in the speedometer
176 Driving systems
When DISTRONIC PLUS is activated, one or two segments ; in the set speed range light up. i For design reasons, the speed displayed in the speedometer may differ slightly from the speed set for DISTRONIC PLUS.
If DISTRONIC PLUS detects a vehicle in front, segments ; between speed of the vehicle in front : and stored speed = light up.

i You will see the stored speed for approx-
imately five seconds when you activate DISTRONIC PLUS.
Activating at the current speed/last stored speed G WARNING If you call up a stored speed and this is dif- ferent from the current speed, the vehicle accelerates or brakes. If you do not know
what the stored speed is, the vehicle may accelerate or brake unexpectedly. There is a risk of an accident. Take the traffic conditions into account before calling up the stored speed. If you do not know what the stored speed is, store the desired speed again.
X Briefly pull the cruise control lever
(Y page 174) towards you ?.
X Remove your foot from the accelerator
pedal. DISTRONIC PLUS is activated. The first time it is activated, the current speed is stored. Otherwise, it sets the vehicle cruise speed to the previously stored value.
Setting a speed Keep in mind that it may take a brief moment until the vehicle has accelerated or braked to the set speed.

speed
; To store the current speed or a lower
speed
X Press the cruise control lever up : for a higher speed or down ; for a lower speed. X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored. DISTRONIC PLUS is activated and adjusts the vehicle's speed to the new speed stored.
X To adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control lever up : or down ; to the pressure point. The last stored speed increases or decrea- ses in 1 km/h increments.
X To adjust the set speed in 10 km/h
increments: press the cruise control lever briefly up : or down ; beyond the pres- sure point. The last stored speed increases or decrea- ses in 10 km/h increments.
i DISTRONIC PLUS is not deactivated if you depress the accelerator pedal. If you accel- erate to overtake, DISTRONIC PLUS adjusts the vehicle's speed to the last speed stored after you have finished over- taking.
Setting the specified minimum distance You can set the specified minimum distance for DISTRONIC PLUS by varying the time span between one and two seconds. With this func- tion, you can set the minimum distance that DISTRONIC PLUS keeps to the vehicle in front, dependent on vehicle speed. You can see this distance in the multifunction display (Y page 175). i Make sure that you maintain the mini- mum distance to the vehicle in front as required by law. Adjust the distance to the vehicle in front if necessary.

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 vehi- cle 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 carriage- way, because of its narrow width. The dis- tance to the vehicle in front will be too short. Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta- cles or stationary vehicles. If, for example, the
DISTRONIC PLUS may detect vehicles that are crossing your lane by mistake. Activating DISTRONIC PLUS at traffic lights with cross- ing traffic, for example, could cause your vehi- cle to pull away unintentionally.
