workshop.
Park Assist
Introduction
This chapter contains information on the followingsubjects:
⇒ Prerequisites
⇒ Looking for a parking space
⇒ Driving into a parking space
⇒ Driving out of a parking space
⇒ Troubleshooting
Park Assist shows parking spaces
which are suitable for parking and
assists the driver when driving into and
out of parking spaces.
Park Assist is an extension of Park Distance Control ⇒ Park Distance Control.
Park Assist automatically steers the vehicle. The driver must control the accelerator, gear changes
and brake!
Driving into a parking space using Park Assist takes place in the following steps:
•Look for a parking space.
•Drive into a parking space.
System limits
The sensors may not always be able to detect objects such as trailer drawbars, thin rails, fences,
posts, trees and open or opening boot lids. This can result in damage to your vehicle.
In some cases, dirt and ice on the sensors could be registered as an obstacle.
Prerequisites
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following prerequisites must be met for driving into and out of parking spaces:
•The traction control system (TCS) must be switched on ⇒ Brake support systems.
•Distance: maintain a distance of 0.5 – -2.0 metres when driving past the parking space.
•The parking space must have at least the dimensions required by Park Assist.
•Speed when driving past the parking space (for parking spaces parallel to the road): not above
40 km/h (25 mph).
•Speed when driving past the parking space (for parking spaces perpendicular to the road): not
above 20 km/h (12 mph).
•Maximum speed: 7 km/h (4 mph). An automatic braking intervention can take place when
driving into a parking space.
The parking manoeuvre can be continued after the automatic brake intervention.
Fast steering wheel movements can cause serious injury.
•During the manoeuvring operation, do not reach for the steering wheel until prompted
to do so by the system.
•Exception: if a dangerous situation occurs, intervene and take over the steering.
WARNING
Park Assist uses parked vehicles, the kerb and other objects as guidance. Please ensure
that the wheels and tyres are not damaged when parking the vehicle. If necessary, stop the
parking procedure in good time to prevent damage to the vehicle.
NOTICE
The automatic braking intervention takes place a maximum of once per parking manoeuvre. The
parking manoeuvre will be cancelled if a speed of approximately 7 km/h (4 mph) is exceeded again.
Automatic cancellation of driving in/out of a parking space
Park Assist cancels the manoeuvre for driving into or leaving a parking space if one of the following
situations occurs:
•The button is pressed.
•The driver intervenes using the steering wheel.
•The driver door is opened.
•The parking operation is not completed within around six minutes.
•There is a system fault.
•TCS is switched off or is taking corrective action.
Automatic braking intervention to minimise damage
In some countries, Park Assist can assist the driver with an automatic braking intervention in certain
situations ⇒.
Depending on the vehicle equipment and certain conditions, e.g. weather, load or inclination of the
vehicle, Park Assist can automatically brake the vehicle before an obstacle. Following this
intervention, the driver must depress the brake pedal. An automatic braking intervention is activated
to minimise damage and ends the parking manoeuvre.
Looking for a parking space
Fig. 157 Instrument cluster display: display of parking modes.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Park Assist has three parking modes ⇒ Fig. 157 (illustration).
Reverse parallel parking.Reverse perpendicular parking.Forward perpendicular parking.
•Drive slowly past a row of parked vehicles, paying attention to the traffic.
•Press the button. Park Assist automatically searches for a suitable parking space on
the front passenger side.
•Stop when Park Assist displays a recommended parking mode on the instrument cluster
display.
•Drive into the parking space when a corresponding prompt ⇒ Fig. 158⑤ is shown on the
instrument cluster display ⇒ Driving into a parking space.
If you want Park Assist to search for a parking space on the opposite side of the road, operate the
turn signal for the corresponding side.
Changing parking mode
If Park Assist has found other alternative parking modes, these will be displayed in a miniature
view. You can select these successively by pressing the button. Park Assist will switch
itself off after selection of all found parking modes. The originally recommended parking mode is
offered when the button is pressed again.
Forward perpendicular parking
If you wish to drive forwards into a perpendicular parking space, select the parking mode Forward
perpendicular parking ⇒ Fig. 157 by pressing the button (if found by Park Assist).
Do not let the Park Assist braking intervention function tempt you to take any risks while
driving – this can cause accidents. The system is not a substitute for the full
concentration of the driver.
•Park Assist has system-related limitations. In some situations, the automatic braking
intervention function is only able to intervene in a limited way or not at all.
•You should always be prepared to brake the vehicle yourself.
•The automatic braking intervention is ended after approximately 1.5 seconds. Depress
the brake pedal of the vehicle yourself following the automatic braking intervention.
WARNING

Requirements for driving out of a parking space while using Park Assist must be fulfilled
⇒ Prerequisites.
•Press the button.
•Use the turn signal and main beam lever to select the direction (left or right) in which you would
like to drive out of the parking space.
•Select reverse gear.
•Release the steering wheel when the following message is shown: Steer. intervention active.
Check area around veh.!
•Carefully press the accelerator.
•Brake when an acoustic signal sounds, the white symbol lights up or when the prompt to
drive forwards appears on the instrument cluster display.
•Depress the brake pedal until Park Assist steering activity has been completed or until the white
symbol disappears on the instrument cluster display.
•Repeat reversing and driving forwards until a corresponding message is displayed on the
instrument cluster. A signal tone may also sound.
•Take over steering with the steering angle set by Park Assist.
•Drive the vehicle out of the parking space when permitted by the traffic situation.

Brake support systems
Information on brake support systems
The vehicle is fitted with brake support systems. The systems can support the driver in critical
driving or braking situations. Brake support systems cannot overcome the limits of physics and
cannot always keep the vehicle under control in every single critical driving or braking situation. The
driver is responsible for driving safety ⇒.
Driving with brake support systems
The brake support systems work when the engine is running. They do not need to be operated
separately.
The brake pedal may pulsate or noises may occur while the brake support systems are regulating.
Continue to apply the necessary amount of brake pressure. Apply the necessary pressure to the
brake pedal consistently. If necessary, steer the vehicle while the brake pedal is depressed.
Fast steering wheel movements can cause serious injury.
•During the manoeuvring operation, do not reach for the steering wheel until prompted
to do so by the system.
•Exception: if a dangerous situation occurs, intervene and take over the steering.
WARNING
Do not let the automatic braking intervention tempt you to take any risks while driving, as
this can cause accidents. The system is not a substitute for the full concentration of the
driver.
•Trailer Assist has system-related limitations. In some situations, the automatic braking
intervention function is only able to intervene in a limited way or not at all.
•You should always be prepared to brake the vehicle yourself.
•The automatic braking intervention is ended after approximately 1.5 seconds at vehicle
standstill. Depress the brake pedal of the vehicle yourself following the automatic
braking intervention.
WARNING
Electronic Stability Control (ESC)
ESC helps to reduce the risk of skidding and to improve driving stability in certain driving situations
⇒.
Depending on the vehicle equipment, ESC can be switched to a Sport mode ⇒ Switching TCS on
and off.
When ESC is regulating, the yellow indicator lamp is shown on the instrument cluster display.
Traction control system (TCS)
The TCS reduces the drive output if wheelspin occurs and adapts the output to suit road surface
conditions. The TCS makes it easier to pull away, accelerate and drive up hills.
Depending on the vehicle equipment, the TCS can be switched off in exceptional circumstances
⇒ Switching TCS on and off.
When the TCS is regulating, the yellow indicator lamp is shown on the instrument cluster
display.
Anti-lock brake system
The anti-lock brake system can prevent the wheels from locking when the brakes are applied up
until the point where the vehicle is nearly stationary and assists the driver in steering the vehicle
and keeping it under control.
Brake assist system
The brake assist system can help to reduce the stopping distance. The brake assist system
reinforces brake pressure when the driver depresses the brake pedal quickly in an emergency
situation.
Do not reduce the pressure on the brake pedal when the brake assist system is regulating. If you
reduce the pressure on the brake pedal, the brake assist system will switch off the brake servo.
Electronic differential lock (EDL and XDS)
EDL brakes the wheel that has lost traction and distributes the driving force to the other drive
wheels.
The EDL switches off automatically under unusually heavy loads to prevent the disc brake from
overheating. The EDL switches back on again automatically as soon as the brake has cooled down.
XDS applies pressure to the brake of the wheel on the inside of the bend. This will improve traction,
helping the vehicle to remain in the required lane longer.
Automatic Post-Collision Braking System
In the event of an accident, the Automatic Post-Collision Braking System can help the driver to
reduce the risk of skidding, and the danger of secondary collisions, through automatic braking.
The Automatic Post-Collision Braking System functions only in front, side and rear collisions when
the airbag control unit detects a corresponding trigger threshold during the accident.
The ESC brakes the vehicle automatically, provided that the hydraulic braking system, the ESC and
the electrical system are undamaged in the accident and remain functional.
The following actions override automatic braking in the event of an accident:
•When the driver depresses the accelerator. No automatic braking occurs.
•When the brake pressure transmitted through the depressed brake pedal is greater than the
brake pressure provided by the system. The vehicle is braked manually.
Switching TCS on and off
Fig. 162 In the centre console: button for switching TCS on and off manually.
If the vehicle does not have sufficient traction, you can switch off TCS in the following situations:
•When driving in deep snow or on loose surfaces.
•When rocking the vehicle backwards and forwards to free it from mud.
Then switch the TCS function back on.
Switching TCS or ESC Sport on and off
Depending on the vehicle equipment, TCS and ESC Sport can be switched off via the Infotainment
system or using the button ⇒ Fig. 162.
When the TCS is switched off, ESC Sport is switched on, or the Off-road or Off-road Individual
driving profiles are active, the yellow indicator lamp is shown on the instrument cluster display.
The intelligent technology used in brake support systems cannot overcome the laws of
physics, and functions only within the limits of the system. Driving fast on icy, slippery or
wet roads can lead to a loss of control of the vehicle and could cause serious injury to the
driver and passengers.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions. Do not let the extra safety afforded by the brake support systems anti-lock
brake system, brake assist system, EDL, TCS and ESC tempt you into taking any risks
when driving.
•The brake support systems cannot defy the laws of motion. Slippery and wet roads will
remain dangerous, even when the ESC and other systems are active.
•Driving too fast on wet roads can cause the wheels to lose contact with the road
surface and aquaplane. The vehicle cannot be braked, steered or controlled once it has
lost contact with the road surface.
•Brake support systems cannot prevent an accident if e.g. you are driving too close to
the vehicle in front or are driving too fast for the specific driving situation.
•Although the brake support systems are very effective and can help to control the
vehicle in difficult driving situations, please always remember that the driving stability
of the vehicle depends on the tyre grip.
•When accelerating on a slippery surface, e.g. on ice and snow, press the accelerator
carefully. The wheels can spin even when brake support systems are active, and this
can lead to a loss of control of the vehicle.
WARNING
The effectiveness of ESC can be reduced considerably if other components and systems
which affect driving dynamics are not serviced properly or are not functioning properly.
This also applies, but not exclusively, to the brakes, tyres and other systems named
above.
•Please always note that modifications and changes to the vehicle can affect the
function of the anti-lock brake system, brake assist system, TCS, EDL and ESC.
•Alterations to the suspension system or the use of non-approved wheel and tyre
combinations can affect the function of the anti-lock brake system, brake assist
system, EDL, TCS and ESC and reduce their effectiveness.
•Suitable tyres are also crucial if ESC is to function optimally ⇒ Wheels and tyres.
WARNING
Driving without the brake servo can considerably increase the braking distance and thus
cause accidents and serious injuries.
•Never allow the vehicle to roll if the engine is switched off.
•If the brake servo does not function or the vehicle is being towed, the brake pedal will
have to be depressed more forcefully as the braking distance will be increased due to
the lack of assistance for the brake system.
WARNING
•Switch off TCS: press the button for around one second.
•Switch on ESC Sport: press the button for longer than three seconds.
•Switch on TCS: press the button again. ESC Sport is switched off.
Troubleshooting
Warning and indicator lamps in the event of faults
Do not drive on! Brake system fault. Seek expert assistance immediately ⇒.Lit
up: ABS failure or defect. Go to a qualified workshop. The vehicle can be braked without ABS.
Lit up: ESC switched off by the system. Switch the ignition on and off. Drive a short distance at a
speed of 15 – 20 km/h (9 – 12 mph) if necessary. If still lights up, seek expert assistance.
Notes on the brake support systems
If you suspect that there is a malfunction in the systems, read and observe the following notes:
•The ESC and TCS can function properly only if all four wheels are fitted with the same tyres.
Any differences in the rolling radius of the tyres can cause the system to reduce engine power
unexpectedly.
•If there is a fault in the anti-lock brake system, the ESC, TCS and EDL will also stop working.
•Operating noises may be heard during the self-regulation processes of the systems explained
above.
Practical equipment
Stowage areas
Introduction
This chapter contains information on the followingsubjects:
⇒ Stowage compartment on the driver side
⇒ Stowage compartment on the front passenger side
⇒ Stowage compartment in the dash panel
⇒ Stowage compartment in the front centre armrest
⇒ Stowage compartment in the roof console (glasses compartment)
⇒ Folding table
⇒ Drawers
⇒ Coat and bag hooks
Use stowage compartments only to stow light or relatively small objects.
A factory-fitted CD changer, Apple iPod adapter, USB connection or multimedia socket
(MEDIA-IN) may be located in the stowage compartment in the centre armrest.
•If the brake warning lamp lights up together with the ABS indicator lamp , the
control function of the anti-lock brake system may have failed. This can cause the rear
wheels to lock quickly when you brake. Locked rear wheels can lead to a loss of
control of the vehicle. If possible, reduce your speed and drive carefully at low speed
to the nearest qualified workshop in order to have the brake system tested. Avoid
sudden braking and driving manoeuvres on the way.
•The anti-lock brake system is not functioning correctly if the ABS indicator lamp
does not go out or comes on while the vehicle is in motion. The vehicle can be stopped
using the normal brakes only (without the anti-lock brake system). The protection
provided by the anti-lock brake system is no longer available. Go to a qualified
workshop as soon as possible.

Tow-starting or towing
Introduction
This chapter contains information on the followingsubjects:
⇒ Notes on tow-starting and towing
⇒ Fitting the rear towing eye
⇒ Fitting the front towing eye
⇒ Fitting the front towing eye (R-Line)
⇒ Driving notes when towing
Tow-starting is where a vehicle is started from it being set in motion by a vehicle that is hitched up
to it.
Towing is where a vehicle that cannot be driven is pulled away with the aid of another vehicle.
Observe any legal requirements when towing or tow-starting.
For technical reasons, vehicles with a discharged 12-volt battery must not be towed.⇒ Jump
starting
Vehicles with Keyless Access must only be towed with the ignition switched on.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the 12-
volt vehicle battery. Depending on the charge level of the 12-volt vehicle battery, the drop in voltage
can be large enough after just a few minutes that electrical consumers in the vehicle will no longer
function, e.g. the hazard warning lights.
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode,
which can lead to serious injuries. Please observe the following in order to reduce the risk
of the 12-volt vehicle battery exploding:
•All work on the 12-volt vehicle battery and the electrical system can cause serious
chemical burns, fire or electric shocks. Always read the warnings and safety
information before carrying out any kind of work on the 12-volt vehicle battery ⇒ 12-
volt vehicle battery.
•Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle
battery.
•Attach the connector cables in the correct order – the positive cable first, followed by
the negative.
•Never connect the negative cable to parts of the fuel system or to the brake lines.
•The non-insulated parts of the battery clamps must not be allowed to touch. The jump
lead attached to the positive terminal on the 12-volt vehicle battery must not touch
electrically conductive parts of the vehicle.
•m/k/a995MK Vehicles with battery in the engine compartment: check the battery
window on the 12-volt vehicle battery. Use a torch for this if necessary. If the display is
light yellow or colourless, do not jump start the vehicle. Seek expert assistance.
•Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The explosive
gas emitted from the 12-volt vehicle battery could be ignited by sparks.
•Do not carry out jump starting if the 12-volt vehicle battery is damaged or if it is or has
ever been frozen.
WARNING
Once the vehicle has been successfully jump-started, go to a qualified workshop and have
the 12-volt vehicle battery checked.
