engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
When the engine is running, you can use the
cruise control lever to limit the speed to any
speed between 30 km/h and the technically
permitted maximum speed of the vehicle. If the
set value of the permanent limiter is lower, then this value applies (Y page 166).
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady speed for a prolonged period.
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account road, weather or traffic conditions. Cruise control is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time and for staying in lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid.
R in poor visibility, e.g. due to fog, heavy rain or
snow.
If a new driver takes over, advise the new driver
of the speed stored.

General notes The limiter restricts the speed of the vehicle. The
limiter brakes automatically in order to adjust
the vehicle's speed to the stored speed.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. On vehi-
cles with automatic transmission, you need to
have selected the manual drive program
M (Y page 150). By doing so, you will make use
of the braking effect of the engine. This relieves
the load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
You can set a variable or permanent limit speed:
R Variable for maximum permissible speeds,
e.g. in built-up areas
R Permanent for a technically permitted max-
imum vehicle speed, e.g. when driving with
winter tyres fitted (Y page 166)
i The speed indicated in the speedometer
may differ slightly from the stored maximum
permissible speed.

Vehicles with manual transmission: the lim-
iter switches off if you shift to a higher gear and
as a result, the engine speed is too low.
i The last speed stored is cleared when you
switch off the engine.
Permanent limiter If you wish to restrict the maximum speed of the
vehicle for an extended period (e.g. when driving with winter tyres), the desired maximum speed
can be set with the permanent limiter.
You can use the on-board computer to limit the
speed to a value between 160 km/h and
240 km/h (Y page 211).
Shortly before the stored speed is reached, it
appears in the multifunction display. When you
confirm the message with aor%, the
display is suppressed until you next switch off
the engine. The speed will only be displayed
again once the engine has been restarted.
The permanent limiter remains active even if the variable limiter is deactivated. The driven speed will remain below the stored speed even in the
event of kickdown. 166

WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards

X Remove your foot from the accelerator pedal.
The first time Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed. Pulling away and driving
X If you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or X If Distance Pilot DISTRONIC is activated:
accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically. Be ready to brake at all
times.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main- tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
i Distance Pilot DISTRONIC is deactivated
when you depress the brake, except when the vehicle is stationary.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+drive pro-
gram (Mercedes-AMG vehicles only), S
(Y page 148) or the manual drive program
(Y page 150). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the E(C in
Mercedes-AMG vehicles:) drive program, the
vehicle accelerates more gently. This setting is
recommended in stop-start traffic.
Changing lanes

DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles when cornering is limited. Your vehi-
cle may brake unexpectedly or late.
R Driving on a different line: Distance Pilot
DISTRONIC may not detect vehicles driving in
a different lane. The distance to the vehicle in
front will be too short.
R Other vehicles changing lane: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
R Narrow vehicles: Distance Pilot DISTRONIC
does not detect the vehicle in front on the
edge of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R Obstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-
cle or stationary vehicle is revealed, Distance Pilot DISTRONIC will not brake for them.
R Distance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRONIC under
the following conditions, the vehicle could
pull away unintentionally:
- at traffic lights with crossing traffic, for
example
- if there is a vehicle in front after a crossing
with the HOLD function activated
In such situations, brake if necessary. Distance Pilot DISTRONIC is then switched off. HOLD function

following situations:
R when pulling away, especially on steep slopes
R when manoeuvring on steep slopes
R when waiting in traffic 172
