m/k/a995MK Vehicles with manual gearbox: change from first to second gear immediately
after setting off. Change to higher gears rapidly.
m/k/a995MK Vehicles with DSG dual clutch gearbox: accelerate slowly and avoid using the
kickdown function.
Gear-change indicator ⇒ Gear-change indicator.
Eco driving profile ⇒ Driving profile selection and 4MOTION Active Control.
Avoid full throttle
Never fully use the maximum speed of the vehicle. Driving at excessive speeds, e.g. above 130
km/h on the motorway, will increase air resistance and thus the amount of force needed to move
the vehicle.
Reduce idling
Drive off immediately with low revs. If you are stopped for a long period, do not allow the engine to
idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine will switch off automatically when the
vehicle is stopping and when the vehicle is stationary ⇒ Start/stop system .
Refuel with moderation
A full fuel tank increases the weight of the vehicle. A fuel tank that is half to three quarters full is
sufficient for urban journeys in particular.
Avoid short journeys
A cold engine has a very high fuel consumption. The optimum operating temperature is reached
only after driving a few miles. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter ⇒ Fig. 116. Plan journeys economically and combine short distances.
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service
life of the vehicle.
Observe the correct tyre pressures
An inadequate tyre pressure does not just mean greater wear, but also increases the rolling
resistance of the tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the vehicle load. Observe the information on the tyre pressure
sticker ⇒ Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System ⇒ Tyre monitoring systems.
Use low viscosity engine oil
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and
spread better and more quickly, especially for cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
In order to keep the drag coefficient of the vehicle as low as possible, remove attachments and
add-on parts such as ski, bicycle or roof carriers after use.
Save electrical energy
The alternator is driven by the engine and generates power for convenience consumers such as the
air conditioning system, window heating and ventilation. Saving electrical energy is easy, e.g.:
•At high ambient temperatures, ventilate the car before starting a journey and drive a short
distance with open window. Only then switch on the air conditioning system.
•Switch off convenience systems as soon as they have served their purpose.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.
WARNING
Conditions that require a manual engine start
The engine must be started manually under the following conditions:
•If the driver door is opened.
•If the bonnet is opened.
Activating and deactivating the start/stop system manually
•Press the button in the centre console ⇒ Fig. 121 to deactivate the system. If the
start/stop system has been deactivated, the indicator lamp in the button lights up.
•Press the button in the centre console again ⇒ Fig. 121 to reactivate the system.
The instrument cluster shows the status of the start/stop system every time the button is
pressed.
If the start/stop system has switched the engine off, it will start again as soon as the system has
been deactivated manually with the button.
Always deactivate the start/stop system manually when driving through water.
Start/stop mode when Adaptive Cruise Control (ACC) is active
The engine will be switched off after the Adaptive Cruise Control (ACC) has brought the vehicle to a
standstill via an active braking intervention ⇒ Adaptive Cruise Control (ACC).
m/k/a995MKVehicles with DSG dual clutch gearbox: when the Adaptive Cruise Control
(ACC) is active, the DSG dual clutch gearbox can shift into coasting mode and the engine can be
switched off with the engine-off coasting function.
In the following instances, the engine will restart when the Adaptive Cruise Control (ACC) is active:
•If the accelerator is depressed.
•When the Adaptive Cruise Control (ACC) has resumed speed and automatic distance control.
•If the vehicle ahead has moved on.
•If the Adaptive Cruise Control (ACC) is deactivated and the vehicle driving in front moved away.
Troubleshooting
The engine stop function may be deactivated if the temperature is above around 38°C (100°F).
In some cases, it may be necessary to restart the engine manually. Follow any
corresponding messages on the instrument cluster display.
The start/stop function is activated automatically if the Eco driving profile is selected on
vehicles with driving profile selection ⇒ Driving profile selection and 4MOTION Active Control.
Always deactivate the start/stop system manually when driving through water.
Manual gearbox: selecting a gear
®
Never switch off the engine or the ignition while the vehicle is in motion. This can lead to a
loss of vehicle control, accidents and serious injuries.
•The airbags and belt tensioners will not work if the ignition is switched off.
•The brake servo will not work when the engine is switched off. That is why more
pressure on the brake pedal is needed to brake the vehicle when the engine is
switched off.
•The power steering will not work when the engine is not running. More power is
needed to steer the vehicle when the engine is switched off.
•When the ignition is switched off, the steering lock may activate and you will no longer
be able to steer the vehicle.
•The start/stop system must be deactivated if work is to be carried out in the engine
compartment.
WARNING
If the start/stop system is used in very high outside temperatures over a long period, the
12-volt vehicle battery can be damaged.
NOTICE
Fig. 122 Gear shift pattern of a 6-speed manual gearbox.
Select a forward gear
The positions of the individual driving gears are shown on the gearshift lever ⇒ Fig. 122.
•Fully depress and hold the clutch pedal.
•Move the gear lever to the required position ⇒.
•Release the clutch to engage.
In some countries, the clutch pedal will have to be depressed fully in order to start the engine.
Selecting reverse gear
•Reverse gear should only be selected when the vehicle is stationary.
•Fully depress and hold the clutch pedal ⇒.
•Move the gear lever to the neutral position and push down.
•Push the gearshift lever fully to the left and then to the front in the reverse gear position
⇒ Fig. 122Ⓡ.
•Release the clutch to engage.
Shifting down
You should always select the next immediate gear when shifting down a gear whilst the vehicle is in
motion. The engine revs should not be too high when doing this ⇒. Damage to the clutch and
the gearbox could occur if at high speeds or high engine revs one or more gears are skipped when
shifting down gear, even if the clutch is not released when doing this ⇒.
Kickdown
On vehicles with speed limiter ⇒ Speed limiter, the kickdown function allows the stored speed limit
to be intentionally exceeded, e.g. when overtaking.
When the accelerator is fully depressed, the speed limiter regulator is temporarily switched off when
the vehicle exceeds the stored speed.
Once the vehicle returns to a speed below the stored speed and the accelerator is no longer fully
depressed, speed limiter regulation becomes active again.
When the Eco driving profile is selected in vehicles with driving profile selection ⇒ Driving profile
selection and 4MOTION Active Control and the accelerator is depressed fully beyond the pressure
point, the engine output is automatically regulated to ensure maximum vehicle acceleration.
Troubleshooting
Clutch does not transmit the entire engine torque. If necessary, remove foot from clutch pedal.
The clutch can overheat, for example if the vehicle pulls off regularly, travels at a crawl for long
periods, or in stop and go traffic. Overheating is indicated by the warning lamp and in some cases
by additional warning lamps and a text message in the instrument cluster display. An acoustic
warning may also be given ⇒.Clutch is defective. Drive on carefully! Seek expert
assistance. Failure to do so could result in considerable damage to the clutch.
When the engine is running, the vehicle will start to move as soon as a gear is engaged
and the clutch released. This also applies when the electronic park brake has been
switched on.
•Never engage reverse gear while the vehicle is in motion.
WARNING
Shifting gears incorrectly to a lower gear can lead to a loss of control of the vehicle, which
can cause accidents and serious injuries.

engine load, your individual driving style and the speed of the vehicle.
– Changing driving modes
The change between positions D and S is carried out by tapping the selector lever once to the rear
out of selector lever position D/S⇒ Fig. 123. The selector lever will always return to selector lever
position D/S.
Using this function it is possible to access the Tiptronic option from both the Sport programme S
and from the Normal programme D⇒ Changing gear using Tiptronic.
Selector lever lock
The selector lever lock in selector lever position P or N prevents gears from being engaged
unintentionally, which would cause the vehicle to move.
To release the selector lever lock, switch on the ignition and press the brake pedal. Then press the
lock button in the selector lever handle in the direction of the arrow ⇒ Fig. 123.
The selector lever lock is not engaged if the selector lever is moved quickly through position N, e.g.
when shifting from reverse to D/S. This makes it possible, for instance, to rock the vehicle
backwards and forwards if it is stuck in snow or mud. The selector lever lock engages automatically
if the brake pedal is not depressed and the lever is in position N for more than approximately
1 second and the vehicle is travelling no faster than approximately 5 km/h (3 mph).
•Gently push the selector lever forwards ⊕ or back ㊀ to shift gear up or down ⇒ Fig. 124.

Driving with DSG dual clutch gearbox
The gearbox changes the forward gears up and down automatically.
Driving down hills
The steeper the gradient, the lower the gear you will need. Lower gears increase the braking effect
of the engine. Never allow the vehicle to roll down mountains or hills in the neutral position N.
•Reduce your speed.
•Push the selector lever from position D/S to the right into the Tiptronic gate ⇒ Changing gear
using Tiptronic.
•Gently push the selector lever to the rear to change down gear.
•OR: shift down using the paddles on the steering wheel ⇒ Changing gear using Tiptronic.
Stopping and pulling away on an uphill gradient
The steeper the uphill gradient, the lower the gear you will need.
If you wish to stop the vehicle or pull away when driving uphill you should use the Auto Hold
function ⇒ Electronic parking brake.
When you stop the vehicle on an incline and the vehicle remains in gear, the vehicle must always
be prevented from rolling by depressing the brake pedal or by applying the electronic parking brake.
The brake pedal or the electronic parking brake should not be released until you pull away ⇒.
Coasting with DSG dual clutch gearbox
In coasting mode, the momentum of the vehicle can be used to save fuel in conjunction with a
foresighted driving style. With the engine-off coasting function, the engine is not just disengaged,
but is also switched off. The engine no longer brakes the vehicle – the vehicle can roll for a longer
distance. The function is available only in the selector lever position D/S and at speeds of
approximately 30 – 130 km/h (18 mph – 80 mph).
An automatic engine start may take place in order to ensure reliable engine restarting and to
guarantee the power supply of the vehicle electrical system.
Triggering coasting
•Select the Eco driving profile from the driving profile selection menu ⇒ Driving profile selection
and 4MOTION Active Control.
•Remove your foot from accelerator pedal. The engine is disengaged and runs in coasting mode.
The vehicle rolls without the braking effect of the engine. The engine is automatically switched
off on vehicles with engine-off coasting function.
Cancelling coasting mode
•Depress the brake pedal briefly.
•OR: depress the accelerator or brake pedal briefly.
•OR: pull a paddle towards the steering wheel.
•OR: press the selector lever to the Tiptronic position.
Kickdown
The kick down function enables maximum acceleration in the selector lever position D/S or in the
Tiptronic position.
•When accelerating, the gearbox automatically shifts up to the next gear shortly before
the maximum permitted engine speed is reached.
•When shifting down a gear manually, the gearbox will not change gear until the engine
can no longer be overrevved.
NOTICE
®
®
If the accelerator pedal is depressed fully, the gearbox will automatically shift to a lower gear,
depending on the speed and engine revs. This will make use of the full vehicle acceleration.
The gearbox does not shift up to the next gear until the engine reaches the maximum engine speed
for the gear.
When the Eco driving profile is selected in vehicles with driving profile selection ⇒ Driving profile
selection and 4MOTION Active Control and the accelerator is depressed fully beyond the pressure
point, the engine output is automatically regulated to ensure maximum vehicle acceleration.
Launch Control Programme
The Launch Control programme gives the vehicle maximum acceleration from a standing start in
vehicles with a DSG dual clutch gearbox.
•Switch off TCS ⇒ Brake support systems.
•Depress and hold the brake pedal with your left foot.
•In selector lever position D/S, select position S. Alternatively, select the Tiptronic position or in
vehicles with driving profile selection select the Sport driving profile ⇒ Driving profile selection
and 4MOTION Active Control.
•With your right foot, depress the accelerator until the engines speed reaches approximately
3,200 rpm.
•Take your left foot off the brake ⇒. The vehicle will start with maximum acceleration.
•Switch the TCS back on after acceleration.
Troubleshooting
®
Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads.
This can cause you to lose control of the vehicle, which can lead to accidents and serious
injuries.
•Always adjust your driving style in accordance with the flow of traffic.
•Only use kickdown or fast acceleration if visibility, weather, road and traffic conditions
permit, and other road users are not put at risk due to the acceleration and the driving
style.
•Please note that the driven wheels could start to spin and the vehicle could skid if the
traction control system (TCS) is switched off, especially if the road is slippery.
•Switch the traction control system (TCS) back on after acceleration.
•Only use the launch control programme, if the road and traffic conditions allow for it.
•You should never endanger other road users through the acceleration of your vehicle
or through your driving style.
WARNING
Never ride the brake pedal. Do not overuse the brake pedal. Constant braking will cause
the brakes to overheat. This can considerably reduce the brake effect, increase the
braking distance and, in certain circumstances, cause the brake system to fail completely.
WARNING
•If you stop the vehicle on an incline, do not attempt to stop it from rolling back by
depressing the accelerator while a position is still selected. The dual clutch gearbox
DSG could overheat and be damaged.
•Never allow the vehicle to roll in position N, particularly if the ignition is switched off.
The DSG dual clutch gearbox will not be lubricated and could be damaged.
•m/k/a995MK Vehicles with Launch Control Programme: accelerating with the
Launch Control programme places heavy strain on all vehicle components. This can
lead to higher rates of wear.
NOTICE
®
®
•Never let the brakes rub by applying light pressure to the brake when it is not
necessary to brake. This will increase levels of wear.
•Before driving down a long, steep gradient, reduce your speed and select a suitable
recuperation level. This will make use of the electric drive braking effect and relieve the
load on the brakes. The brakes could otherwise overheat and possibly fail. The brakes
should only be used to slow or stop the vehicle.
NOTICE
•In addition, if the cruise control system or Adaptive Cruise Control (ACC) is switched off:
if the vehicle speed is less than approximately 80 km/h (50 mph) or the brake pedal is
depressed.
•In addition, if the cruise control system or Adaptive Cruise Control (ACC) is active: if the
stored speed is exceeded.
Deactivating downhill speed control automatically:
•If the downhill gradient becomes less steep.
•OR: if the gearbox shifts up a gear because the engine speed is higher than approximately
4,500 rpm.
•Or in addition if the cruise control system or Adaptive Cruise Control (ACC) is active: if
the stored speed can be maintained.
Hill Descent Control
When Hill Descent Control is active, the indicator lamp lights up white.
When Hill Descent Control is not active, the indicator lamp lights up grey. The system is
switched on, but is not regulating.
The Hill Descent Control system automatically brakes all four wheels to limit the speed when driving
forwards and reversing on steep downhill gradients. The wheels will not lock as the anti-lock brake
system remains active. In vehicles with a manual gearbox, Hill Descent Control adjusts the target
speed so that the engine speed does not drop below the idling speed.
If you enter a downhill slope travelling at a speed under 30 km/h (18 mph), the vehicle speed will be
limited to a speed between min. 2 km/h (1 mph) and max. 30 km/h (18 mph). The driver can use the
accelerator pedal and the brakes to alter the speed in this range. The control speed will be set
again as soon as the driver takes their foot off the accelerator or brake pedal.
However, this can work only if the tyres have sufficient grip on the road. Hill Descent Control
cannot work on an icy or slippery slope, for example.
Hill Descent Control is automatically activated if the following conditions are met:
•The engine is running.
•The Off-road driving profile is selected ⇒ Driving profile selection and 4MOTION Active
Control.
•The speed is under 30 km/h (18 mph) (the function display is visible on the instrument
cluster display).
•The downhill gradient is at least 10 %.
•You do not brake or accelerate.
The Hill Descent Control function will be deactivated when the downhill gradient is less than 5 %.
The intelligent downhill speed control technology cannot overcome the laws of physics,
and functions only within the limits of the system. Never allow the extra convenience
afforded by pull-away assist systems to tempt you into taking any risks when driving.
•Unintentional vehicle movements can cause serious injury.
•The downhill speed control cannot replace the full concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•Downhill speed control cannot hold the vehicle in all hill start situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).
WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if this is not
ensured.
•The downhill speed control is only a support function and may not be able to brake the
vehicle sufficiently in all situations when driving downhill.
•The vehicle may become faster despite the downhill speed control being in operation.
WARNING
Steering
Information on steering
The steering should be locked every time you leave the vehicle to make it more difficult for the
vehicle to be stolen.
Steering
The power steering is not hydraulic. It is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy
supply while steering.
In vehicles with driving profile selection, the selected driving profile can affect the behaviour of the
power steering ⇒ Driving profile selection and 4MOTION Active Control.
Electronic steering column lock in vehicles with starter button
The steering column will be locked if the driver door is opened and the ignition is switched off. For
this, the vehicle should be stationary and, if necessary, the gear selector lever should be in position
P.
If the ignition is not switched off until after the driver door is opened, the electronic steering column
will only be locked when the vehicle is locked using the vehicle key or the sensor in the door
handle.
Mechanical steering column lock (steering lock) in vehicles with an
ignition lock
The steering column is locked if the vehicle key is removed from the ignition lock when the vehicle
is stationary. Turn the steering wheel slightly until the steering lock clicks into place.
Insert the vehicle key into the ignition lock to unlock the steering lock. Turn the steering wheel
slightly to take the load off the steering lock mechanism. Hold the steering wheel in this position and
turn the ignition on.
Electromechanical steering
The power steering provided by the electromechanical steering system automatically adjusts to the
vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
only functions when the engine is running.
You will need considerably more strength than normal to steer the vehicle if the power steering is
reduced or has failed completely.
Counter steering assistance
Counter steering assistance provides the driver with power steering in critical driving situations.
Additional steering power helps the driver when counter steering ⇒.
The intelligent Hill Descent Control technology cannot overcome the laws of physics, and
functions only within the limits of the system. Never allow the extra convenience afforded
by pull-away assist systems to tempt you into taking any risks when driving.
•Unintentional vehicle movements can cause serious injury.
•The Hill Descent Control cannot replace the full concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•A Hill Descent Control System may not be able to always hold the vehicle on uphill
gradients or brake it sufficiently on all slopes going downhill (e.g. if the ground is
slippery or icy).
WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if this is not
ensured.
•The Hill Descent Control system is only a support function and may not be able to
brake the vehicle sufficiently in all situations when driving downhill.
•The vehicle may accelerate despite the Hill Descent Control system.
WARNING
