134 Operating the climate control system
The auxiliary heating/ventilation automati- cally adjusts to changes in temperature and weather conditions. For this reason, the aux- iliary heating could switch from ventilation mode to heating mode or from heating mode to ventilation mode. The auxiliary heating switches off when the engine is switched off. The auxiliary ventila- tion switches off when you turn the key to key position 2(Y page 143). The auxiliary heating switches off automati- cally after 30 minutes. You cannot use the auxiliary ventilation to cool the vehicle interior to a temperature lower than the outside temperature.
Before switching on X Turn the key to position 2 in the ignition
lock (Y page 143).
X Set the desired temperature. Auxiliary heating or ventilation can also be switched on if the manually set climate con- trol is activated. Optimum comfort can be attained when the system is set to automatic mode. Set the temperature to 22 †. The auxiliary heating/ventilation can be acti- vated or deactivated using the remote control or the button on the centre console. The on-board computer can be used to spec- ify up to three departure times, one of which may be preselected (Y page 224).
Auxiliary heating Important safety notes G DANGER If the exhaust pipe is blocked or sufficient ventilation is not possible, toxic exhaust fumes can enter the vehicle, especially car- bon monoxide. This is the case, e.g. in enclosed spaces, or if the vehicle is stuck in snow. There is a risk of fatal injuries. You should switch off the auxiliary heating in enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is stuck in snow and you must leave the auxiliary heating running, keep the exhaust pipe and the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open a window on the side of the vehicle away from the wind. G WARNING When the auxiliary heating is switched on, parts of the vehicle can become very hot. Flammable material such as leaves, grass or twigs may ignite if they come into contact with hot parts of the exhaust system for extended periods. There is a risk of fire. When the auxiliary heating is switched on, make sure that no flammable material can come into contact with hot vehicle compo- nents.
! Operating the auxiliary heating/ventila- tion draws on the vehicle battery. After you have heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehi- cle interior to the set temperature. This occurs without using the heat of the running engine. The auxiliary heating is operated directly using the vehicle's fuel. For this rea- son, the fuel tank must be at least ¼ full to ensure that the auxiliary heating functions.

Useful information
i This Owner's Manual describes all mod- els, series and optional equipment for your vehicle that were available at the time of going to press. National variations are pos- sible. Note that your vehicle may not be equipped with all of the functions descri- bed. This is also the case for systems and functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24).
Running-in notes Important safety notes New brake pads/linings and discs that have been replaced only achieve optimum braking effect after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal.
The first 1500 km If you treat the engine with sufficient care from the very start, you will be rewarded with excellent performance for the remainder of the engine's life. RDrive at varying vehicle speeds and engine
speeds for the first 1500 km.
RAvoid overstraining the vehicle during this
period, e.g. driving at full throttle.
RChange gear in good time, before the rev counter needle is Ô of the way to the red area of the rev counter.
RDo not shift down a gear manually in order
to brake.
Vehicles with automatic transmission: RTry to avoid depressing the accelerator
pedal beyond the point of resistance (kick- down).
After 1,500 km, you may gradually bring the vehicle up to full road and engine speeds.
Additional running-in notes for AMG vehicles: RDo not drive at speeds above 140 km/h for
the first 1,500 km.
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
i You should also observe these notes on running-in if the engine or parts of the drive train on your vehicle have been replaced.
Driving Important safety notes G WARNING Objects in the driver's footwell may restrict the clearance around the pedals or block a depressed pedal. This jeopardises the oper- ating and road safety of the vehicle. There is a risk of an accident. Stow all objects securely in the vehicle so that they do not get into the driver's footwell. Always fit the floormats securely and as pre- scribed in order to ensure that there is always sufficient room for the pedals. Do not use loose floormats and do not place several floor- mats on top of one another. G WARNING Unsuitable footwear can hinder correct usage of the pedals, e.g.: Rshoes with thick soles Rshoes with high heels Rslippers There is a risk of an accident. Wear suitable footwear to ensure correct usage of the pedals. 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
Driving 143
more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. G WARNING If the parking brake has not been fully released when driving, the parking brake can: Roverheat and cause a fire Rlose its hold function. There is a risk of fire and an accident. Release the parking brake fully before driving off.
! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only set the automatic transmission to the respective drive positions when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. Otherwise, you could damage the drive train.
! AMG vehicles: avoid full-load operation and engine speeds greater than 5000 rpm when the engine is cold. This helps to pro- tect the engine and avoids uncomfortable driving.

Manual transmission Gear lever ! Only engage gear when the clutch pedal
is depressed.
! When shifting to 5th and 6th gear, you must press the shift lever to the right. Oth- erwise, you could shift unintentionally into 3rd or 4th gear and damage the engine or transmission. If you shift down at too high a speed (trans- mission braking), this can cause the engine to overrev, leading to engine damage. Do not use the clutch bite point to keep the vehicle stationary on uphill gradients. There is otherwise a risk of damaging the clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing
a trailer, you must shift into gear 1, 2 or 3
in good time. This uses the engine's braking effect. This relieves the load on the brake system and prevents the brakes from over- heating and wearing too quickly.Gear lever Reverse gear 1 to 6 Forward gears

A Neutral
No power is transmitted from the engine to the drive wheels. Releasing the brakes will allow you to move the vehicle freely, e.g. to push it or tow it. If ESP® is deactivated or faulty: only shift the transmission to posi- tion N if the vehicle is in danger of skidding, e.g. on icy roads. When you switch off the engine, the automatic transmission automati- cally shifts into neutral N.
7 Drive
The automatic transmission changes gear automatically. All forward gears are available.
Changing gear The automatic transmission shifts to the indi- vidual gears automatically when it is in trans- mission position D. Gearshifting is deter- mined by: Rthe selected drive program (Y page 155) Rthe position of the accelerator pedal Rthe road speed
Driving tips Accelerator pedal position Your style of driving influences how the auto- matic transmission shifts gear: Rlittle throttle: early upshifts Rmore throttle: late upshifts
Holding the vehicle stationary on uphill gradients G WARNING If the clutch overheats, the electronic man- agement system is automatically deactivated.
This interrupts the power transmission. The vehicle may, for example, roll backwards on gradients. There is a risk of an accident. Never hold the vehicle stationary on uphill gradients by depressing the accelerator.
The clutch may overheat if you hold the vehi- cle stationary on uphill gradients by depress- ing the accelerator pedal. If the clutch over- heats, a warning tone sounds. All vehicles (except AMG vehicles): the Stop vehicle Shift to P Leave engine running display message appears in the mul- tifunction display. You will only be able to continue your journey once the clutch has cooled down and the display message in the multifunction display has disappeared. AMG vehicles: the Trans. oil overhea‐ ted Drive on with care display message appears in the multifunction display. Do not hold the vehicle stationary on uphill gradients by depressing the accelerator pedal. Instead, only ever hold the vehicle sta- tionary on uphill gradients by: Rdepressing the brake pedal Ractivating the HOLD function Rengaging the electric parking brake
Kickdown AMG vehicles: it is only possible to use kick- down in temporary manual drive program M. For further information on the manual drive program M, see (Y page 156). Use kickdown for maximum acceleration: X Depress the accelerator pedal beyond the
pressure point. The transmission shifts to a lower gear depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached. The automatic transmission shifts back up.

In drive program M, you can change gear yourself using the steering wheel gearshift paddles. If you pull the left or right steering wheel gear- shift paddle when in automatic drive program E (drive program C on AMG vehicles) or S, the automatic transmission shifts into drive pro- gram M for a limited time. Depending on which gearshift paddle is pulled, the auto- matic transmission immediately shifts into the next gear down or up. AMG vehicles: you can activate drive pro- gram M RACE START (Y page 181) using the steering wheel gearshift paddles. i You can only change gear with the steer- ing wheel gearshift paddles when the trans- mission is in position D.

Automatic drive program Drive program E (drive program C on AMG vehicles) is characterised by the following: Rcomfort-oriented engine settings. Roptimal fuel consumption resulting from the automatic transmission shifting up sooner.
Rthe vehicle pulling away more gently in
forward and reverse gears unless the accel- erator pedal is depressed fully.
Rincreased sensitivity. This improves driving
stability on slippery road surfaces, for example.
Rthe automatic transmission shifting up sooner. This results in the vehicle being driven at lower engine speeds and the wheels being less likely to spin.
Drive program S is characterised by the fol- lowing: Rsporty engine settings. Rthe automatic transmission shifting up
later.
Ras a result of the later automatic transmis- sion shift points, the fuel consumption pos- sibly being higher.
Manual drive program Introduction In manual drive program M, you can change gear yourself by using the steering wheel gearshift paddles. For this, the transmission must be in position D. The gear currently selected and engaged is shown in the multi- function display. Manual drive program M differs from drive programs E (drive program C on AMG vehi- cles) and S with regard to spontaneity, responsiveness and smoothness of gear changes.

Activating the manual drive program Activating permanently X Press the program selector button
(Y page 155) repeatedly until M appears in the multifunction display. Manual drive program M remains active until drive program E (drive program C on AMG vehicles) or S is engaged.
Activating temporarily X Pull the right or left steering wheel gearshift
paddle (Y page 156). M is shown in the multifunction display. Manual drive program M is temporarily active. Depending on which gearshift pad- dle is pulled, the automatic transmission immediately shifts into the next gear down or up.
i When manual drive program M is activa- ted via the steering wheel gearshift pad- dles, the temporarily active manual drive program M will be deactivated automati- cally after a limited time, if the driving sit- uation permits. The automatic transmis- sion switches to the previously activated drive program E (drive program C on AMG vehicles) or S. When driving on downhill gradients, the temporarily active manual drive program M will only be deactivated if the accelerator pedal is depressed while the vehicle is rolling downhill.
Shifting up X Pull the right-hand steering wheel gearshift
paddle (Y page 156). The automatic transmission shifts up to the next gear.
i All vehicles (except AMG vehicles): in order to prevent engine damage the auto- matic transmission automatically shifts up: Rif the maximum engine speed on the cur-
rently engaged gear is reached and Ryou depress the accelerator pedal.
AMG vehicles: ! In manual gearshift program M, the auto- matic transmission does not shift up auto- matically even when the engine limiting speed for the current gear is reached. When the engine limiting speed is reached, the fuel supply is cut to prevent the engine from overrevving. You must make sure that the engine speed does not reach the red area of the rev counter. Otherwise, there is a risk of engine damage.

Deactivating the manual drive program X Press the program selector button (Y page 155) repeatedly until E or S appears in the multifunction display.
Deactivating the temporary manual drive program X Pull and hold the right steering wheel gear- shift paddle until the automatic transmis- sion shifts into the last active automatic drive program E (drive program C on AMG vehicles) or S.
i When manual drive program M is deacti- vated, the automatic transmission in auto- matic drive program E (drive program C on AMG vehicles) or S may shift from the cur- rent gear into a higher or lower gear. This is dependent on the position of the accel- erator pedal, speed and load.
Before the engine speed reaches the red area, an upshift indicator will be shown in the mul- tifunction display. X If the colour in the speedometer multifunc- tion display changes to red and the UP dis- play message is shown, shift up a gear.
Downshifting X Pull the left-hand steering wheel gearshift
paddle (Y page 156). The automatic transmission shifts down to the next gear.
i If you slow down or stop without shifting
down, the automatic transmission auto- matically shifts down.
i For maximum acceleration, pull the left- hand steering wheel gearshift paddle until the transmission selects the optimum gear for the current speed.
i If the engine exceeds the maximum
engine speed when shifting down, the auto- matic transmission protects against engine damage by not shifting down.
Kickdown AMG vehicles: it is only possible to use kick- down in temporary manual drive program M. You can also use kickdown for maximum acceleration in manual drive program M. X Depress the accelerator pedal beyond the
pressure point. The transmission shifts to a lower gear depending on the engine speed.
X Shift back up once the desired speed is
reached.
i During kickdown, you cannot shift gears using the steering wheel gearshift paddles.
i If you apply full throttle, the automatic transmission shifts up to the next gear when the maximum engine speed is reached. This prevents the engine from overrevving.

Refuelling Important safety notes G WARNING Fuel is highly flammable. If you handle fuel incorrectly, there is a risk of fire and explo- sion. You must avoid fire, naked flames, creating sparks and smoking. Switch off the engine and, if applicable, the auxiliary heating before refuelling. G WARNING Fuels are poisonous and hazardous to health. There is a danger of injury. Do not swallow fuel or let it come into contact with skin, eyes or clothing. Do not inhale fuel vapours. Keep fuels out of the reach of chil- dren. If you or others come into contact with fuel, observe the following: RWash the fuel off any affected areas of skin
with water and soap immediately.
RIf you get fuel in your eyes, rinse them thor- oughly with clean water immediately. Seek immediate medical attention.
RIf fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
RChange any clothing that has come into
contact with fuel immediately. G WARNING Electrostatic charge can cause sparks and thereby ignite fuel vapours. There is a risk of fire and explosion. Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump nozzle. This discharges any electrostatic charge that may have built up. G WARNING Vehicles with a diesel engine: If you mix diesel fuel with petrol, the flash point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running, components in the exhaust system may over- heat unnoticed. There is a risk of fire. Never refuel with petrol. Never add petrol to diesel fuel.
