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.

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.
WARNING
•Gently push the selector lever forwards ⊕ or back ㊀ to shift gear up or down ⇒ Fig. 124.

selector lever is not in the Tiptronic gate.
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
•After manual release, carefully press the cover onto the centre console while ensuring that the
electrical wires are positioned correctly.
Emergency programme
There is a fault in the system if all the displays on the instrument cluster for the selector lever
positions have a light background. The DSG dual clutch gearbox is running in an emergency
programme. The vehicle can still be driven in the emergency programme, but only at reduced
speed and not in all gears.
In vehicles with a DSG dual clutch gearbox, you may no longer be able to select reverse gear.
In all cases you should have the DSG dual clutch gearbox checked by a qualified workshop
immediately.
Overheating of the DSG dual clutch gearbox
The DSG dual clutch gearbox can become too hot, for example, if the vehicle pulls off
frequently, drives at crawling speed for long periods, or in stop-and-go traffic. Overheating is
indicated by the warning lamp and in some cases by a text message in the instrument cluster
display. A signal tone may also be given. Stop the vehicle and allow the gearbox to cool down ⇒
.
The vehicle does not move forwards or backwards even though a position
has been selected
If the vehicle will not move in the required direction, the system may have selected the position
incorrectly. Depress the brake pedal and reselect the position.
If the vehicle still does not move in the required direction, there is a system fault. Seek expert
assistance and have the system checked.
Downhill speed control
If the vehicle is being held on the Auto Hold function, the green indicator lamp lights up.
Switch off Auto Hold if necessary ⇒ Auto Hold function.
The Hill Descent Control system in vehicles with a DSG dual clutch gearbox helps when braking
and travelling downhill ⇒. This system uses the braking power of the engine, rather than the
brakes directly.
The DSG dual clutch gearbox selects the best gear for the circumstances, depending on the
steepness of the hill and the current speed. The selector lever must be in position D/S. The downhill
speed control is not active in Tiptronic mode.
As the downhill speed control system can shift down only as far as third gear, it may be necessary
to activate the Tiptronic mode when driving down particularly steep inclines. When in Tiptronic
mode, select second or first gear manually in order to make use of the braking effect of the engine
and to relieve the load on the brakes.
The start/stop system is automatically deactivated as long as downhill speed control is active.
Activating downhill speed control automatically:
•If the downhill gradient is greater than approximately 6%.
•AND: if the selector lever is in position D/S.
®
®
®
®
®
Never move the selector lever out of the position P if the electronic parking brake is not
switched on. Otherwise the vehicle could move unexpectedly if it is stopped on an incline,
which could lead to accidents and serious injuries.
WARNING
The DSG dual clutch gearbox will become damaged if the vehicle is allowed to roll for a
long period of time or at a high speed (for example while being towed) with the selector
lever in position N and the engine switched off.
NOTICE
®
•If the display indicates that the gearbox is overheating for the first time, the vehicle will
have to be parked safely or driven faster than 20 km/h (12 mph).
•If the text message and signal tone are repeated every ten seconds, the vehicle must be
parked safely immediately and the engine switched off. Allow the gearbox to cool down.
•In order to prevent damage to the gearbox, you should not drive on until the acoustic
warning stops. You should not pull away or drive the vehicle at very low speeds while
the gearbox is overheated.
NOTICE
®
®
•Accelerate only to the speed you need to climb the slope. Too much acceleration can cause the
wheels to spin and lead to a loss of control of the vehicle. Too little acceleration increases the
probability of stalling the engine.
•Never attempt to stop or turn on a slope.
•Avoid allowing the engine to stall.
•Do not change gear or engage the clutch when climbing a slope.
•Use the Off-road display ⇒ Off-road display.
If you cannot continue to drive up a hill
•Never turn the vehicle around on an incline.
•If the engine has stalled, depress the footbrake and start the engine again.
•Select the reverse gear and reverse back in a straight line slowly.
•Use the foot brake to keep a constant speed until you have reached a safe place.
Driving downhill
Never exceed the inclination angle of the vehicle! If, in an emergency, you have to traverse the
slope when driving down it and the vehicle threatens to tip over, steer downhill along the maximum
gradient.
There is an increased risk of rolling over when driving downhill. Concentrate on steering the vehicle
in particular when driving downhill.
Use the off-road display on steep downhill stretches ⇒ Off-road display.
•Drive down steep inclines in first gear.
•Use the foot brake sparingly in order not to lose control of the vehicle.
•If it is possible and not dangerous, drive straight down the slope on the maximum gradient (in
the fall line).
•Do not press the clutch and do not select neutral.
Traversing a slope
Fig. 133 Steering downhill along the maximum gradient.
Never try driving up or down an incline if it is too steep for the vehicle. The vehicle could
slide away, tip over or roll.
•The gradient of the slope up or downhill may be no greater than the maximum
permissible gradient for the vehicle.
•Always drive up and downhill along the maximum gradient only.
•Never turn the vehicle when driving up or downhill. The vehicle could tip over or slide
away sideways.
•If the engine stops or if you cannot drive on for any reason: stop the vehicle and
depress the brake pedal. Start the engine again. Select the reverse gear, release the
brake pedal and using the engine braking effect to carefully reverse in a straight line
along the fall line. Keep the vehicle speed low and constant.
•If you are unable to start the engine, keep your foot steady on the brake pedal and
allow the vehicle to roll back down the track you made when driving up the hill. Keep
the vehicle speed low and constant.
•Never let the vehicle coast out of gear backwards down a slope. You could lose control
over the vehicle.
WARNING
Fig. 134 On steep slopes, you should always use the doors pointing up the hill to get out of the
vehicle.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Traversing a slope is one of the most dangerous off-road situations ⇒.
It may look harmless, but you should not underestimate the difficulty and danger of traversing a
slope. A vehicle could slide away, tip over or roll when in this position. This can cause severe or
fatal injuries for all vehicle occupants.
Check whether you can use a safer route before driving across a slope.
If you have to drive at an angle, make sure the ground is as firm as possible. The vehicle is more
likely to slip, dip and tip over on slippery or soft ground. Always be aware that uneven ground
makes the slope steeper. The vehicle could otherwise tip over and start to roll.
When driving across a slope, the wheels on the lower side of the vehicle must never enter dips or
hollows. The wheels on the upper side of the vehicle must never roll over bumps, for example
stones, tree trunks or other obstacles.
If the vehicle threatens to tip over, steer immediately into the fall line and depress the accelerator
slightly ⇒ Fig. 133. If it is not possible to drive along the fall line, then steer uphill and depress the
accelerator slightly.
The centre of gravity should be as low as possible. The weight of all vehicle occupants should be
evenly distributed. People with a larger or heavier build should sit on the higher side of the vehicle.
Remove the roof carrier and secure heavy items. The vehicle could tip over if items were to slide
suddenly ⇒.
Driving through ditches
First read and observe the introductoryinformation and safety warnings⇒
Introduction
•Check whether the tilt angle and gradient entry/exit angles are small enough to drive through
the ditch with the vehicle ⇒.
•If possible, drive through the ditch at an acute angle ⇒.
•The tilt angle may not get too large when driving through the ditch.
Never try to traverse a slope, particularly if it is too steep for the vehicle. The vehicle could
slide away, tip over or roll. Please note the following points in order to reduce the risk of
accidents and serious injuries:
•You should never underestimate the difficulty and danger of traversing a slope. Never
choose an unsafe route or take a risk which could endanger you or your passengers. If
you are in any doubt about the safety of the route, turn round and choose another way.
•The vehicle can lose its grip and slide away sideways, tip over or roll over and roll
down the hill.
•The wheels on the lower side of the vehicle must never enter dips or hollows. The
wheels on the upper side of the vehicle must never roll over bumps, for example
stones, tree trunks or other obstacles.
•Please ensure that you can steer in the fall line on a route driving across a slope.
Choose another route if this is not guaranteed. If the vehicle threatens to tip over, steer
immediately into the fall line and depress the accelerator slightly ⇒ Fig. 133.
•If the vehicle is stopped when traversing a slope, avoid sudden movements in the
vehicle. The vehicle can lose its grip and slide away sideways, tip over or roll over and
roll down the hill.
•Vehicle occupants should never leave the vehicle via the doors facing down the hill
when parked sideways on a steep hill. This could cause the centre of gravity to move.
The vehicle could otherwise tip over or roll over and roll down the hill. To avoid this,
always leave the vehicle carefully on the side that is facing uphill ⇒ Fig. 134.
•When getting out the vehicle, please ensure that the vehicle door which opens uphill
does not close with its own weight or through carelessness thus potentially causing
injury.
WARNING
