Lights and visibility
7. Always take the vehicle key with you when you leave the vehi- cle.
Switch on the hazard warning lights to warn other road users, for example:
● reaching the tail end of a traffic jam,
● there is an emergency
● your vehicle breaks down due to a technical fault,
● you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. The two turn signal turn signal lamps   and the turn signal
lamp in the switch  will flash at the same time. The hazard warning lights
also work when the ignition is switched off.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than
80 km/h (50 mph), the brake light flashes several times per second to warn
vehicles driving behind. If you continue braking, the hazard warning lights
will come on automatically when the vehicle comes to a standstill. They
switch off automatically when the vehicle starts to move again.
WARNING
● The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the atten-
tion of other road users to your stationary vehicle.
● Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire!
Note
● The battery will run down if the hazard warning lights are left on for a
long time, even if the ignition is switched off.
● The use of the hazard warning lights described here is subject to the rel-
evant statutory requirements. 
Main beam assist*
Main beam assist (Light Assist)
The main beam assist operates, within the limits of the system and depend-
ing on the environmental and traffic conditions, as of a speed of 60 km/h
(40 mph) when it switches on automatically, and is then deactivated again
below 30 km/h (20 mph) ⇒ 
. This is managed via a camera situated on
the base of the interior rear vision mirror.
The main beam assist generally detects illuminated areas and deactivates
the main beam when passing through a town, for example. 

Electronic Stability Control (ESC)
Description
EI ESC helps to improve safety. It reduces the tendency to skid and improves
the stability and roadholding of the vehicle. EI ESC detects critical handling
situations, such as vehicle understeer or oversteer, or wheelspin on the
driving wheels. It stabilises the vehicle by braking individual wheels or by
reducing the engine torque. The warning lamp will flash on the instrument
panel when the ESC is intervening .
ESC includes the Anti-lock brake system (ABS), the brake assist system, the
traction control system (ASR), electronic differential lock (EDL), electronic
self-locking*, selective torque control* and tractor-trailer sway mitigation*.
ESC also helps stabilise the vehicle by changing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking until the vehicle
has reached a virtual standstill. You can continue to steer the vehicle even
when the brakes are on full. Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal pulsate while the ABS is
working.
Brake assist system
The brake assist system can reduce the required braking distance. The brak-
ing force is automatically boosted if you press the brake pedal quickly in an
emergency. You must keep pressing the brake pedal until the danger has
passed. Traction control system (ASR)
In the event of wheelspin, the traction control system reduces the engine
torque to match the amount of grip available. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the spinning wheel and directs
the power to the other driven wheel. This function is available up to a speed
of around 100 km/h, 62 mph).
To prevent the disc brake of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle can still
be driven. The EDL will switch on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control the following: Tractor-trailers
tend to sway. When the swaying of the trailer is felt by the vehicle and de-
tected by the ESC, it will automatically brake the towing vehicle within the
limits of the system and mitigate the sway. Tractor-trailer sway mitigation is
not available in all countries.
Electronic self-locking*/Selective torque control*
When driving around bends, an electronic self-locking intervenes. The front
wheel on the inside of the curve, or the two inside wheels, respectively, are
selectively braked as required. This minimises the traction of the front
wheels, allowing you to take bends with greater precision and neutrality. In
certain circumstances, where roads are wet or snow-covered, the respective
system may not intervene.
