Warning and indicator lamps
A WARNING
The intelligent technology of the pull-away assist systems cannot overcome the laws of physics or system-related vehicle limitations. Never let the extra convenience afforded by pull-away assist systems tempt you into tak-ing any risks when driving-this can cause accidents.
• Unintentional vehicle movements can cause serious Injury.
• The pull-away assist systems cannot re-place the driver's full concentration.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions.
• Pull-away assist systems 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). m First read and observe the introductory information and safety warnings & on page 282.

Hill Descent Assist
Fig. 228 In the centre console: button for switch-ing the Hill Descent Assist on and off.
l"'""'('n First read and observe the Introductory L-W.I Information and safety warnings & on page 282.
The Hill Descent Assist system supports
the driver when driving down a steep in-
cline by actively braking the vehicle.
The Hill Descent Assist reduces the engine speed and brakes actively so that the vehicle travels con-stantly at walking speed =>&.
The requirement for regulation is, among other things, that the ground allows enough grip. The Hill Descent Assist system cannot fulfil its function when driving down an icy or slippery slope.
Hill Descent Assist is regulating
• If the Hill Descent Assist is switched on using the button and the indicator lamp lights up.
• AND: the speed is less than 30 km/h (19 mph).
• AND: the gradient is at least 10%.
• AND: if the accelerator and brake are not de-pressed.
• AND: if the engine is running.
Regulation is stopped if the vehicle is accelerated or braked by the driver during regulation. The regu-lation restarts once the requirements are met again.
Hill Descent Assist does not regulate
• If the gradient is less than 10%.
• OR: The speed is greater than 30 km/h (19 mph).
• OR: If the driver brakes or accelerates.
A WARNING
Always be prepared to brake the vehicle. Ac-cidents and Injuries could occur if this is not ensured.
• The Hill Descent Assist 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 Assist system.
Switching the Hill Descent Assist on and off
• To switch the Hill Descent Assist on, press the @=>Fig. 228 button in the centre console at speeds under approximately 30 km/h (19 mph). The indicator in the instrument cluster dis-play lights up. The indicator lamp flashes when the Hill Descent Assist system is applying the brake.
r::l The Hill Descent Assist system also works if W you reverse down a slope. • Press the button@ =>Fig. 228 in centre con-sole again to switch off the Hill Descent Assist. The indicator lamp in the instrument cluster display is switched off.

When the highest level is reached, the distance re-turns to the lowest level when the button is press-ed again.
The distance level can also be set using the Q or Q buttons on the multifunction steering wheel im-mediately after the(!) button on the multifunction steering Fig. 241 has been pressed.
Select the Settings menu, Assist systems submenu, ACC to set the distance to be used when the ACC is switched on 24.
Setting the gearbox programme
The acceleration response can be influenced by the gearbox programme selected. The programme can be set Using the ACC option in the Assistant submenu in the Settings menu. The following gearbox programmes can be selected:
• Normal
• Sport
• Eco
The following conditions can prevent the adaptive cruise control (ACC) from reacting:
• If the accelerator is depressed.
• If no gear is selected.
• If the ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to the vehicle.
• If the vehicle is reversing.
• System version 1: if the vehicle is travelling faster than approximately 160 km/h (1 00 m ph).
• System version 2: if the vehicle is travelling faster than approximately 210 km/h (130 mph).
A WARNING
If you do not maintain the minimum distance to a vehicle In front and the difference In speed between the two vehicles is so great that the braking action of the adaptive cruise control (ACC) is insufficient, you are In dan-ger of colliding with the vehicle in front. You should reduce the vehicle speed immediately with the foot brake.
• The adaptive cruise control (ACC) may not be able to detect all driving situations cor-rectly.
• Leaving your foot on the accelerator means that the adaptive cruise control (ACC) will not brake automatically. This is because manual acceleration overrides the system.
• You should always be prepared to brake the vehicle yourself.
• Observe country-specific regulations re-garding the minimum distance.
m The set speed will be deleted if the ignition or L!.J the adaptive cruise control (ACC) is switched off.
m The adaptive cruise control (ACC) is auto-L!.J matically deactivated when the traction con-trol system (TCS) is deactivated.
m In vehicles with a start/stop system, the en-L!.J gine is switched off automatically during the stationary phase of adaptive cruise control (ACC) and is then restarted for moving off. Switch off the adaptive cruise control (ACC) temporarily in the following
situations
1""111 First read and observe the introductory L-J,:.IJ Information and safety warnings & on page 298.
The adaptive cruise control (ACC) should be switched off in the following situations due to sys-tem limitations &:
304 I While driving
• When turning off roads, driving around round-abouts, narrow curves, joining motorways, exiting from motorways or driving through road works, to prevent the vehicle from unnecessarily accelerat-ing to the set speed in these situations
• When driving through a tunnel as this situation could impair the system function.
• On roads with more than one lane, if other vehi-cles are driving more slowly in the fast lane. The slower vehicles In the other lane would be overtak-en from the right side in this case.
• In heavy rain, snow or spray as vehicles travel-ling ahead cannot be monitored sufficiently or maybe cannot be monitored at all. .,.
