NoteFor vehicles without stabilization control (ESC), during a TCS intervention the
control indicator blinks in the instrument cluster.
Electronic Differential Lock (EDL)
Read and observe
on page 106 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
The EDL switches off automatically in order to avoid excessive heat generation
on the brake of the wheel being braked. The vehicle can continue to be driven
and has the same characteristics as a vehicle not fitted with EDL. Once the
brakes have cooled down, there is an automatic re-activation of EDL.
Hydraulic Brake Assist (HBA)
Read and observe
on page 106 first.
The HBA increases the braking effect and helps to reduce the braking dis-
tance.
The HBA is activated by the very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically deactivated when the brake pedal is re-
leased.
Hill Hold Control (HHC)
Read and observe
on page 106 first.
When driving on slopes, HHC allows you to move your foot from the brake ped-al to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake pedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active from a 5% slope if the driver's door is closed. HHC is always
only active on slopes when in forward or reverse start off.

Function
108
Activation/deactivation
108
The parking aid (hereinafter referred to only as a system) draws attention via
acoustic signals and an indication in the radio or navigation display when ma-
noeuvring around obstacles in the vicinity of the vehicle.
The system uses ultrasound waves to calculate the distance between the
bumper and an obstacle. The ultrasonic sensors are integrated in the rear
bumper.
WARNING■ The system only serves as an assistance and does not relieve the driver
of the responsibility for the vehicle operation.■
Moving persons or objects may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. For this reason, such people or
objects may not be recognised by the system sensors.
■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people to be not recog-
nised by the system.
■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer draw-bars etc. behind your vehicle. Such
obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors clean, snow-and ice-free and do not cover with any
objects of any kind, otherwise the system functioning may be impaired.■
The system function may be limited under adverse weather conditions
(heavy rain, water vapour, very low or high temperatures etc.).
■
Additionally installed accessories such as e.g. bicycle carriers can impair the
function of the parking aid.

radio instruction manual, navigation system user guide.
Activation/deactivation
Read and observe
and on page 107 first.
The system is activated automatically by engaging the reverse gear. This is
confirmed by a brief audible signal.
The system is deactivated by disengaging reverse gear.
Displaying an error
If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. Seek help
from a specialist garage.
NoteFor vehicles with a factory-fitted towing device, the system cannot be activa-
ted when towing a trailer.
Cruise Control System
Introduction
This chapter contains information on the following subjects:
Functioning
108
Operating Description
109
The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The status where the CCS maintains the speed is referred to hereinafter as the
control .
WARNING■
The CCS only serves as an assistance and does not relieve the driver of
the responsibility for the vehicle operation.■
Always adjust the speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Functioning
Read and observe
on page 108 first.
Basic requirements for starting the control The CCS is activated.
On vehicles with a manual transmission , the second gear or higher must
be engaged.
On vehicles with an automatic transmission , the selector lever must be in
the D, S position or in the Tiptronic position.
The current speed must be higher than 20 km/hr.
This is only possible within the range which is permitted by the power output
and braking power of the engine.
108Driving
In a lot of countries sufficient trade-in networks have been created, where you
can trade-in your vehicle. After you trade-in your vehicle, you will receive a
confirmation documenting the recycling in accordance with environmental reg-
ulations.
Note
You can find more detailed information about the trade-in and recycling of old
cars from a specialist garage.
Washing vehicle
Introduction
This chapter contains information on the following subjects:
Washing by hand
122
Automatic car wash systems
122
Washing with a high-pressure cleaner
123
The best way to protect your vehicle against harmful environmental influences
is frequent washing.
The longer insect residues, bird droppings, tree sap, road and industrial dust,
tar, soot particles, road salt and other aggressive deposits remain adhering to
the paintwork of your vehicle, the more detrimental their destructive effect
can be. High temperatures, such as those caused by intensive sun's rays, ac-
centuate this caustic effect.
It is essential to also thoroughly clean the underside of the vehicle at the end
of the winter.
WARNINGWhen washing your vehicle in the winter: Water and ice in the braking sys-
tem can affect the braking efficiency – risk of accident!
CAUTION
The temperature of the water used for cleaning must not exceed 60 °C – risk
of damaging the vehicle.
For the sake of the environment
Only wash the vehicle at washing bays intended for this purpose.Washing by hand
Read and observe
and on page 122 first.
Soak the dirt with plenty of water and rinse as well as possible.
Clean the vehicle with a soft sponge, a washing glove or a washing brush.
Work from the top to the bottom – starting with the roof.
For stubborn dirt, agents specifically intended for this purpose are to be used. Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas.
Give the vehicle a good rinse after washing it and dry it off using a chamois
leather.
WARNINGProtect your hands and arms from sharp-edged metal parts when cleaning
the underfloor or the inside of the wheel housings or the wheel trims – risk
of cuts!
CAUTION
■ Only apply slight pressure when cleaning the vehicle's paintwork.■Do not wash your vehicle in bright sunlight – risk of paint damage.
Automatic car wash systems
Read and observe
and on page 122 first.
The usual precautionary measures must be taken before washing the vehicle
in an automatic car wash system (e.g. closing the windows and the sliding/tilt-
ing roof etc.).
If your vehicle is fitted with any particular attached parts, such as a spoiler,
roof rack system, two-way radio aerial etc., it is best to consult the operator of
the car wash system beforehand.
After an automatic wash with wax treatment, the lips of the wipers should be
cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
122General Maintenance
WARNINGThere is risk of injuries, poisoning, chemical burns, explosions or fire when
working on the battery and on the electrical system. It is essential to com-
ply with the general applicable safety rules as well as the warning instruc-
tions outlined below.■
Keep the vehicle battery away from people who are not completely inde-
pendent, especially children.
■
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect your eyes by wearing safety goggles or a
face shield – risk of blindness!
■
Always wear protective gloves, eye and skin protection when handling
the vehicle battery.
■
The battery acid is strongly corrosive and must, therefore, be handled
with the greatest of care.
■
Corrosive fumes in the air irritate the air passages and lead to conjunctivi-
tis and inflammation of the air passages in the lungs.
■
Battery acid corrodes dental enamel and, if it comes into contact with the
skin, causes deep wounds that take a long time to heal.
■
If any battery acid comes into contact with your eyes, rinse the affected
eye immediately with clean water for several minutes and consult a doctor
immediately!
■
Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water.
■
If you swallow battery acid, consult a doctor immediately!
WARNING■ The use of open flames and light should be avoided.■Smoking and radio triggering activities should be avoided.■
Never use a damaged vehicle battery – risk of explosion!
■
Never charge a frozen or thawed vehicle battery – risk of explosion and
chemical burns!
■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of
explosion and chemical burns.
CAUTION
■ Improper handling of the vehicle battery may cause damage.■Ensure that battery acid does not come into contact with the bodywork – risk
of damage to the paintwork.■ If the vehicle has not been driven for more than 3-4 weeks, the battery will
discharge. Prevent the battery from discharging by disconnecting the battery's
negative terminal (-) or continuously charging the battery with a very low
charging current.■
Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light.
■
If the vehicle is frequently used for making short trips, the vehicle battery
will not have time to charge up sufficiently and may discharge.
For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations.
Note
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.

›
Open the cover in the direction of the arrow » Fig. 128.
The battery cover is installed in reverse order.
139Inspecting and replenishing
WARNING■When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical consumers and disconnect the negative
terminal (-).
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START-STOP system, the pole terminal of the charger
must not be connected directly to the negative terminal of the vehicle battery,
but only to the engine earth » page 158, Jump-starting in vehicles with the
START-STOP system .
Replacing
Read and observe
and on page 139 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.
Disconnecting and reconnecting
Read and observe
and on page 139 first.
Disconnecting
›
Switch off the ignition.
›First, disconnect the negative terminal (-) first, then the positive (+) terminal
of the battery.
Connecting›
First, connect the positive (+) first, then the negative (-) battery terminal.
After disconnecting and re-connecting the vehicle battery, the following func-
tions or devices are partially or completely inoperative.

system user manualTime settings» page 29
CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 139 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the battery is put under high levels of strain. This manifests it-
self by the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and
rear window heaters have their power limited or are shut off completely in
the event of an emergency.
