Driving tips Short journeys ! Vehicles with a diesel particle filter: if the vehicle is mostly driven for short dis- tances, it is possible that malfunctions may occur during the automatic cleaning of the diesel particle filter. This may lead to fuel collecting in the engine oil and cause engine failure. Therefore, if you frequently

drive short distances, you should take a 20
minute trip on a motorway or rural road at least every 500km.Brakes 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 On long and steep downhill gradients, espe- cially if the vehicle is laden or towing a trailer, you must select shift range 1, 2 or 3 (Y page 153) in good time. i This also applies if you have activated
cruise control or SPEEDTRONIC.
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. If you need additional braking, depress the brake pedal repeatedly rather than continuously.
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.
If the brakes have been subjected to a heavy load, do not stop the vehicle immediately, but drive on for a short while. This allows the air- flow 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. This improves the grip of the brakes.
Wet road surfaces If driving in heavy rain for a prolonged period of time without braking, there may be a delayed reaction from the brakes when brak- ing for the first time. This may also occur after the vehicle has been washed. 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.
Limited braking performance on salt- treated roads If you drive on salt-treated roads, a layer of salt may form on the brake discs and pads. This can increase the braking distance con- siderably. RApply the brakes occasionally in order to prevent any salt build-up. Ensure that you do not endanger other road users when doing so.
RCarefully depress the brake pedal at the end of the journey and when starting the next journey.
RMaintain a much greater distance to the
vehicle in front.
166 Driving tips
New brake pads/linings New brake pads/brake pads and discs that have been replaced only achieve optimum braking effect after several hundred kilome- tres of driving. Compensate for the reduced braking effect 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.
High-performance brake system for AMG vehicles The high-performance brake system is designed for high loads. This may lead to noise when braking. This is dependent on: Rspeed Rbraking force Renvironmental conditions, such as temper-
ature and humidity.
The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driv- ing style and operating conditions. For this reason, it is impossible to state a mileage (service life) that will be valid under all circumstances. An aggressive driving style will lead to high wear. You can obtain further information about this from your Mercedes- Benz Service Centre.
Parking brake G WARNING If you must brake the vehicle with the parking brake, the braking distance is considerably longer and the wheels could lock. This increa- ses the risk of skidding and an accident.
Only use the parking brake to brake the vehi- cle when the service brake is faulty. Do not apply the parking brake too firmly. If the wheels lock, release the parking brake until the wheels begin turning again.
When you apply the parking brake to brake the vehicle, the brake lamps do not light up. If you drive on wet roads or dirt-covered sur- faces, road salt and/or dirt could get into the parking brake. In order to prevent corrosion and a reduction in the braking power of the parking brake, observe the following: Rpull the parking brake upwards with the
release button depressed from time to time before beginning the journey (Y page 164).
Rdrive for approximately 100 m at a maxi-
mum speed of 20 km/h.
Tyre traction G WARNING Whereas the vehicle can be fully controlled at a certain speed on dry roads, you must reduce your speed on wet or icy roads to achieve the same road safety. You could otherwise cause an accident. Pay particular attention to the road conditions at temperatures around freezing point. If ice has formed on the road surface (e.g. from fog), a thin film of water rapidly forms on the ice when you brake, considerably reduc- ing tyre traction. Drive with particular care in such weather conditions.
Driving on slippery surfaces ! If possible, do not let the drive wheels spin. Otherwise, you could damage the drive train.
X Engage the differential locks if necessary
(Y page 204).
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 60 cm
Ryou should drive no faster than walking
pace
Off-road fording ! The water depth must not exceed 60 cm. Note that the possible fording depth is less in flowing water.
! Under no circumstances should you
accelerate before entering the water. The bow wave could cause water to enter and damage the engine and neighbouring assemblies.
! Do not open any of the vehicle's doors while fording. Otherwise, water could get into the vehicle interior and damage the vehicle's electronics and interior equip- ment.
Driving tips
167
The fording depth must not exceed 60 cm when the vehicle is loaded and ready to drive. Loaded and ready to drive means: a full tank, all fluids topped up and the driver is in the vehicle. i You may only drive through freshwater. RObserve the safety notes (Y page 169) and the general notes (Y page 169) on off-road driving.
REstablish how deep the water is and the
characteristics of the body of water before fording.
RSwitch off the air-conditioning system. RDeactivate the auxiliary heating. RShift the transfer case to LOW
RANGE(Y page 201).
REngage the differential locks, if necessary
RRestrict the shift range to 1 or
(Y page 204).

RAvoid high engine speeds. REnter and exit the water at a flat place and
at a steady walking pace.
RDrive slowly and at a constant speed
through the water.
RDo not stop and do not switch off the
engine.
RWater offers a high degree of resistance, the ground is slippery and, in some cases, unstable. Therefore, it is difficult and dan- gerous to pull away in the water.
REnsure that a bow wave does not form as
you drive.

Parking the vehicle after heavy loads on the engine ! Vehicles with a diesel engine: your
vehicle's exhaust gas turbocharger may get very hot under heavy engine load, e.g. dur- ing: Rtrailer towing Rlonger motorway journeys at high speed Rlonger journeys through mountainous
terrain
X Let the engine run for approximately
another two minutes while the vehicle is stationary before switching off the engine. This way, the exhaust gas turbocharger can cool down more effectively.
Winter driving General notes 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. G WARNING If you have fitted snow chains to the front wheels, they may scrape against the vehicle body or chassis components. This could cause damage to the vehicle or the tyres. There is a risk of an accident. To avoid hazardous situations: Rnever fit snow chains on the front wheels Rfit snow chains to the rear wheels in pairs.
At the onset of winter, have your vehicle win- terproofed at a qualified specialist workshop. Observe the notes in the "Winter operation" section (Y page 319).
Driving with summer tyres Observe the notes in the "Winter operation" section (Y page 319).
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.
You should drive particularly carefully on slip- pery road surfaces. Avoid sudden accelera- tion, steering and braking manoeuvres. If the vehicle threatens to skid or cannot be stopped when moving at low speed: X Move the transmission to position N. X Try to bring the vehicle under control by
using corrective steering.
i For more information on driving with
snow chains, see (Y page 320).
Off-road driving Important safety notes G WARNING If you drive up a steep incline at an angle or turn on a steep incline, the vehicle could slip sideways, tip and overturn. There is a risk of an accident. When driving up an incline, drive into the line of fall (upwards or downwards in a straight line) and do not turn.
! G 350 BlueTEC:
The level in the AdBlue® tank needs to be sufficiently high to compensate for driving at extreme angles when driving off-road. Before driving off-road, make sure that the tank contains a minimum of ten litres.
When driving off-road, sand, mud and water, possibly mixed with oil, for example, could get into the brakes. This may lead to a reduction in braking performance or total brake failure as a result of increased wear. The braking characteristics will vary, depending on the substances that get into the brakes. Clean the brakes after driving off-road. If you notice grinding noises or a reduction in braking per- formance, have the brake system checked at a qualified specialist workshop immediately. Adapt your driving style to the altered braking characteristics. Driving off-road increases the possibility of damage to the vehicle, which may cause assemblies or systems to fail. Adapt your driving style to the conditions of the terrain. Drive carefully. Have vehicle damage rectified immediately at a qualified specialist work- shop.

Observe the following when on hilly roads: RDo not shift the transmission to position
N.
RIf the gradient is too steep for your vehicle,
back up in reverse gear.
RDo not continuously depress the brake
pedal, as doing so could cause you to lose control.
General notes H Environmental note Protection of the environment is of primary importance. Treat nature with respect. Observe all prohibiting signs.
Read this section before driving your vehicle off-road. Practise by travelling over more gen- tle off-road terrain first. The following driving systems are specially adapted to off-road driving: R4ETS (Y page 62) RTransfer case (Y page 201) RDifferential locks (Y page 204) Observe the following notes: Rstop your vehicle and, if necessary, shift the
transfer case to LOW RANGE(Y page 202) before driving off- road.
RAMG vehicles: to shift the transfer case to
LOW RANGE, deactivate the ECO start/ stop function (Y page 146).
Rengage the differential locks, if necessary
(Y page 204)
i ABS, 4ETS, ESP® and BAS are deactivated
while the differential locks are engaged. This allows the front wheels to lock briefly, so that they can dig into a loose surface. However, please note that locked wheels skid and can no longer steer.
170 Driving tips
RCheck that items of luggage and loads are
stowed safely and are well secured (Y page 271).
RTo avoid damaging the vehicle, make sure there is always sufficient ground clearance. RAlways keep the engine running and in gear
when driving on a downhill gradient.
RAlways keep the engine running and in gear
when driving on a slope.
RDrive slowly and evenly, if necessary at
walking pace.
REnsure that the wheels are in contact with
the ground at all times.
RDrive with extreme care on unknown off-
road routes where visibility is poor. For safety reasons, get out of the vehicle first and survey the off-road route.
RCheck the depth of water before fording
rivers and streams.
RWhen fording, do not stop and do not
switch off the engine.
RLook out for obstacles such as rocks, holes,
tree stumps and furrows.
RAlways keep the doors, the rear door or tailgate (G-Class Cabriolet), the side win- dows and the sliding sunroof closed while the vehicle is in motion.
RSwitch off cruise control and variable
SPEEDTRONIC.
RDo not stray from marked routes or paths. RAdapt your speed to the terrain. The
rougher, steeper or more ruts on the ter- rain, the slower your speed should be. RDrive slowly and at a constant speed
through the water. Ensure that a bow wave does not form as you drive.
ROn sand, drive quickly to overcome the roll- ing resistance. Otherwise, the vehicle could dig itself into the sand.
RDo not jump with the vehicle as this will
interrupt the vehicle's propulsion.
RAvoid high engine speeds. Drive at appro-
priate engine speeds.
RAlways check the vehicle for damage after
off-road driving.
i Information about retrofitting special all- terrain tyres is available from any qualified specialist workshop.
i Do not use the HOLD function when driv- ing off-road, on steep uphill or downhill gra- dients or on slippery or loose surfaces. The HOLD function cannot hold the vehicle on such surfaces.
Checklist before driving off-road ! If the engine oil warning lamp lights up during the journey, stop the vehicle in a safe place as soon as is possible. Check the engine oil level. The warning given by the engine oil warning light must not be ignored. Continuing your journey when the symbol is shown may result in engine dam- age.
X Engine oil level: check the engine oil and
top it up if necessary. Only then does the engine receive enough oil when the vehicle is standing on a steep incline.
X G 350 BlueTEC: have the AdBlue® level
checked at a qualified specialist workshop (Y page 160).
X Tyre-change tool kit: check that the jack
is working and make sure you have the wheelbrace, a robust tow cable and a fold- ing spade in the vehicle.
X Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the wheels/tyres.
X Replace any missing valve caps. X Replace dented or damaged wheels. X Carry a sound spare wheel.
Checklist after driving off-road Driving over rough terrain places greater demands on your vehicle than driving on nor- mal roads. After driving off-road, check the vehicle. This allows you to detect damage promptly and reduce the risk of an accident to yourself and other road users. X Shift the transfer case to HIGH
RANGE(Y page 202).
X Disengage the differential locks
(Y page 204).
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates. X Clean the wheels and tyres with a water jet
and remove any foreign objects.
X Clean the wheels, tyres, wheel arches and
the vehicle underside with a water jet; check for any foreign objects and damage.
X Check whether twigs or other parts of
plants have become trapped. These increase the risk of fire and can damage fuel pipes, brake hoses or the rubber bel- lows of the axle joints and propeller shafts.
X After the trip, examine without fail the
entire undercarriage, wheels, tyres, brakes, bodywork structure, steering, chassis and exhaust system for damage.
X After driving for extended periods across sand, mud, gravel, water or in similarly dirty conditions, have the brake discs, wheels, brake pads/linings and axle joints checked and cleaned.
X If you notice strong vibrations after off-road
driving, check for foreign objects in the wheels and drive train and, if necessary, remove them. Foreign objects can disturb the balance and cause vibrations.
Driving tips

Driving on sand Observe the following rules when driving on sand: RShift the transfer case to LOW
RANGE(Y page 202).
RAvoid high engine speeds. RLimit the shift range of the automatic trans-
mission according to the off-road condi- tions.
RDrive quickly to overcome the rolling resist- ance. Otherwise, the vehicle could dig itself into the sand.
RDrive in the tracks of other vehicles if pos- sible. Make sure that the ruts are not too deep, that the sand is firm enough and that your vehicle has sufficient ground clear- ance.
Tyre ruts and gravel roads ! Check that the ruts are not too deep and that your vehicle has sufficient clearance. Otherwise, your vehicle could be damaged or bottom out and get stuck.
Observe the following rules when driving along ruts in off-road terrain or on roads with loose gravel: RShift the transfer case to LOW
RANGE(Y page 202).
RAvoid high engine speeds. RObserve the safety notes (Y page 169) and the general notes (Y page 169) on off-road driving.
RRestrict the shift range of the automatic
transmission to 1(Y page 153).
RDrive slowly. RWhere ruts are too deep, drive with the
wheels on one side on the middle section of turf if possible.
Driving over obstacles ! Obstacles could damage the floor of the vehicle or components of the chassis. Ask passengers for guidance when driving over

RAccelerate gently and make sure that the
wheels are gripping.
RAvoid high engine speeds, except when driving on sandy and muddy routes with high driving resistance.
RWhen driving down a slope, use the braking
power of the engine. Observe the engine speed; do not overrev the engine.
RSelect a shift range appropriate to the gra-
dient.
RBefore tackling steep downhill gradients,
select shift range 1(Y page 153).
RAlways check the brakes after driving off-
road.
Maximum gradient-climbing capability On good road surfaces and with the LOW RANGE gear selected, the maximum gradi- ent-climbing capability is 80%. i If the load on the front axle is reduced
when pulling away on a steep uphill slope, the front wheels have a tendency to spin. 4ETS recognises this and brakes the wheels accordingly. The rear wheel torque is increased and it is easier to pull away.
Hilltops When driving up an uphill gradient, slightly reduce pressure on the accelerator immedi- ately before reaching the brow of the hill. Make use of the vehicle's own impetus to travel over the brow. This style of driving prevents: Rthe vehicle from lifting off the ground on the
brow of a hill
Rloss of traction Rthe vehicle from travelling too quickly down
the other side.
Driving downhill RBefore tackling steep downhill gradients,
select shift range 1(Y page 153).

This way you use the engine's braking effect to reduce the speed. If this is not sufficient, brake gently. When doing so, make sure that the vehicle is facing in the direction of the line of fall.
RObserve the notes on driving in mountain-
ous terrain (Y page 173).
RDrive slowly. RDo not drive at an angle down steep
inclines. Steer into the line of fall and drive with the front wheels aligned straight. Oth- erwise, the vehicle could slip sideways, tip and overturn.
RCheck that the brakes are working normally
after a long downhill stretch.
Driving systems Cruise control Important safety notes G WARNING The brake pedal moves when cruise control brakes the vehicle. A foot in the area under the brake pedal could become trapped. The movement of the pedal, and therefore the vehicle's ability to brake, may be restricted by objects in the area under the brake. There is a risk of an accident and injury. Do not place your foot under the brake pedal. Keep the area under the brake pedal free from obstructions.
If you fail to adapt your driving style, cruise control can neither reduce the risk of acci- dent nor override the laws of physics. Cruise control cannot take account of road, weather and traffic conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Adjust your driving style to the traffic conditions. Only engage cruise control when the current road, weather and traffic conditions permit it to be done safely. Drive carefully and maintain a suitable distance to the vehicle in front.
174 Driving systems
Do not use cruise control: Rin traffic conditions that do not allow you
to drive at a constant speed, e.g. heavy traffic, on winding roads or off-road
Ron slippery road surfaces. Braking or accel- erating could 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
General notes Cruise control maintains a constant road speed for you. 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. 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.

SPEEDTRONIC Important safety notes 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 you fail to adapt your driving style, SPEED- TRONIC can neither reduce the risk of acci- dent nor override the laws of physics. SPEED- TRONIC cannot take account of road, weather and traffic conditions. SPEEDTRONIC 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 lane. Only engage SPEEDTRONIC when the current road, weather and traffic conditions permit it to be done safely. Drive carefully and main- tain a suitable distance to the vehicle in front.
General 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. i The speed indicated in the speedometer
may differ slightly from the limit speed stored.

wards B.
or X Briefly press the cruise control lever in the
direction of arrow A. LIM indicator lamp ; in the cruise control lever goes out. Variable SPEEDTRONIC is deactivated. Cruise control is selected.
It is not possible to deactivate variable SPEEDTRONIC by braking. Variable SPEEDTRONIC is deactivated auto- matically if you depress the accelerator pedal beyond the pressure point (kickdown), but only if your current speed does not differ by more than 20 km/h from the stored speed. G 350 BlueTEC: you will hear a warning tone.
Permanent SPEEDTRONIC You can use the on-board computer to limit the speed permanently to a value between 160 km/h(e.g. for driving on winter tyres) and the maximum speed (Y page 223). 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 you fail to adapt your driving style, DIS- TRONIC PLUS can neither reduce the risk of accident nor override the laws of physics. DISTRONIC PLUS cannot take account of road, weather and traffic conditions. DIS- TRONIC PLUS is only an aid. You are respon- sible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Only engage DISTRONIC PLUS when the current road, weather and traffic conditions permit it to be done safely, and adapt your driving style accordingly. Drive carefully and maintain a suitable dis- tance to the vehicle in front. If DISTRONIC PLUS detects a risk of collision but cannot sufficiently decelerate the vehicle in order to maintain the set distance, you will

be warned visually and acoustically. DIS- TRONIC PLUS cannot prevent a collision with- out your intervention. An intermittent warn- ing tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately in order to increase the distance from the vehicle in front, or take evasive action, provided it is safe to do so. DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. Therefore, always pay attention to traffic conditions even when DISTRONIC PLUS is activated. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. If DISTRONIC PLUS is activated, the vehicle brakes automatically in certain situations. This can happen unexpectedly, especially when towing or in a car wash. There is a risk of an accident. In these or similar situations, deactivate DISTRONIC PLUS. If you want DISTRONIC PLUS to assist you, the following activation conditions must be fulfilled (Y page 184) and the radar sensor system must be operational.
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. On long and steep downhill gradients, espe- cially 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 DISTRONIC PLUS detects a slower-moving vehicle in front, your vehicle is braked in order to maintain the preset distance to the vehicle in front.
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, DISTRONIC operates in the speed range between 0 km/h and 200 km/h. Do not use DISTRONIC PLUS on roads with steep gradients.

When driving at speeds below 30 km/h, you can activate DISTRONIC PLUS if the vehicle in front has been detected and is shown in the multifunction display. If the vehicle in front is no longer detected and displayed, DIS- TRONIC PLUS switches off and you will hear a tone. X Briefly pull the cruise control lever towards

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. 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.
