MERCEDES-BENZ AMG GT COUPE 2018 Owners Manual

This pr
ovides traf fic tr ave lling behind you with an
eve n more noticeable warning.
If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once
th eve hicle is stationar y.When you pull away
again, the hazard warning lights will switch off
automatically at appr oximately 10km/h. Yo u
can also switch off the hazard warning lights
using the hazard warning button. Cruise control and limiter
Fu
nction of cruise control
Cruise cont rolre gulates the speed totheva lue
selec tedby the driver.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Cruise contro l is operated using the cor respond‐
ing steering wheel buttons. You can store any
speed abo ve30 km/h up tothe maximum speed
or up tothe set winter tyre limit. If
yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo r maintaining a safe dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.

The segments extending from the cur rent
st ored speed tothe end of the scale, or to
th e set winter tyre limit, light up in the
speedome ter.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the engine's brak‐
ing ef fect. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor. 13 8

Fu
nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed limits, e.g. in built-up
areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode.
The variable limiter is operated using the cor re‐
sponding steering wheel buttons. You can store
any speed from 30 km/h to250 km/h or up to
th e set winter tyre limit. You can also per form
settings while theve hicle is stationary if the
ve hicle has been star ted.
If yo ufa ilto adapt your driving style, the limiter
can neither reduce therisk of an accident nor
ove rride the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. The
limiter is only an aid. You are responsible for
maintaining a safe dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane. Displa
