MERCEDES-BENZ E CLASS WAGON 2023 Owners Manual

Functions of OM-road ABS\bOM-road ABS is activated automatically when
you select the F or G drive program.
OM-road ABS is specially adapted for driving oM-
road:
= The front wheels lock cyclically during braking.
= The braking distance is shortened due to the
digging-in eMect.
System limits
= OM-road ABS functions at speeds below
25 mph (40 km/h).
= If OM-road ABS intervenes, the ability to steer
may be restricted.
Function of BAS
&WARNING Risk of an accident caused by a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased.
Depress the brake pedal with full force in
emergency braking situations. ABS pre-
vents the wheels from locking.
The Brake Assist System (BAS) supports your emergency braking situation with additional brakeforce.
If you depress the brake pedal quickly, BAS is
activated:
= BAS automatically boosts the brake pressure.
= BAS can shorten the braking distance.
= ABS prevents the wheels from locking.
The brakes will function as usual once you release the brake pedal. BAS is deactivated.
Function of ESP n
&WARNING
Risk of skidding if ESP n
is
deactivated
If you deactivate ESP n
, ESP n
cannot carry out
vehicle stabilization.
ESP n
should only be deactivated in the
following situations.*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.
The Electronic Stability Program (ESP n
) can moni-
tor and improve driving stability and traction in
the following situations within physical limits:
= When pulling away on wet or slippery roads.
= When braking.
If the vehicle deviates from the direction desired
by the driver, ESP n
can stabilize the vehicle by
intervening in the following ways:
= One or more wheels are braked.
= The engine output is adapted according to the
situation.

qActivating/deactivating the HOLD function&WARNING Risk of an accident due to the
HOLD function being active when you
leave the vehicle
If the vehicle is only braked with the HOLD
function it could, in the following situations,
roll away:
= If there is a malfunction in the system or in
the power supply.
= If the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant.
Always secure the vehicle against rolling away before you leave it.
Requirements
= The vehicle is stationary.
= The driver\bs door is closed or the seat belt on
the driver\bs side is fastened.
= The vehicle has been started or has been
automatically switched oM by the ECO start/
stop function.
= The electric parking brake is released.
= Active Distance Assist DISTRONIC is deactiva-
ted.
= The transmission is in position [, ^ or \\.

&WARNING Risk of accident and injury due
to the vehicle rolling away
Aser a short time, Hill Start Assist no longer
holds the vehicle.
Swisly move your foot from the brake
pedal to the accelerator pedal. Do not
leave the vehicle when it is being held by
Hill Start Assist.
ATTENTION ASSIST

q Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto-
nous journeys, e.g. on highways and trunk roads.
If ATTENTION ASSIST detects indicators of fatigue
or increasing lapses in concentration on the part
of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration in
time. The system is not a substitute for a well-res-
ted and attentive driver. On long journeys, take
regular breaks in good time that allow for ade-
quate recuperation.
You can choose between two settings:
= Standard: normal system sensitivity.
= Sensitive: higher system sensitivity. The driver
is warned earlier and the attention level detec-
ted by ATTENTION ASSIST is adapted accord-
ingly.
If drowsiness or increasing lapses in concentra-
tion are detected, the ATTENTION ASSIST Take
a Break! warning appears in the Instrument Dis-
play. You can acknowledge the message and take
a break where necessary. If you do not take a
break and ATTENTION ASSIST continues to detect
increasing lapses in concentration, you will bewarned again aser a minimum of 15 minutes.You can have the following status information for
ATTENTION ASSIST displayed in the assistance
menu of the on-board computer:
= The length of the journey since the last break.
= The attention level determined by ATTENTION
ASSIST:
- the fuller the circle, the higher the atten-
tion level determined
- as your attention wanes, the circle in the
center of the display becomes smaller
If ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warning, the
System Suspended message appears.
If a warning is given in the Instrument Display, the multimedia system oMers to search for a rest
area. You can select a rest area and start naviga-
tion to this rest area. This function can be activa-
ted and deactivated in the multimedia system.
If ATTENTION ASSIST is deactivated, the Û
symbol appears in the assistance graphic in the Instrument Display. Aser the vehicle is started,
ATTENTION ASSIST is automatically activated. The last selected sensitivity level remains stored.Driving and parking193

System limits
ATTENTION ASSIST is active in the 37 mph
(60 km/h) to 124 mph (200 km/h) speed range.
Particularly in the following situations, ATTENTION ASSIST only functions in a restricted manner andwarnings may be delayed or not occur:
= If you have been driving for less than approx-
imately 30 minutes.
= If the road condition is poor (uneven road sur-
face or potholes).
= If there is a strong side wind.
= If you adopt a sporty driving style (high corner-
ing speeds or high rates of acceleration).
= If Active Steering Assist is activated and active
(  page 205).
= If the time has been set incorrectly.
= If you change lanes and vary your speed fre-
quently in active driving situations.
The ATTENTION ASSIST drowsiness or alertness
assessment is reset and restarted when continu- ing the journey in the following situations:
= If you switch oM the vehicle.=
If you unfasten your seat belt and open the
driver\bs door (e.g. to change drivers or take a break).

q Function of cruise control
Cruise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, forexample, the
stored speed is not deleted. If you remove your foot from the accelerator pedal aser overtaking,
cruise control will resume speed regulation back to the stored speed.
You can store any speed above 15 mph
(20 km/h) up to the maximum design speed.
Observe the notes on driving systems and yourresponsibility; you may otherwise fail to recognizedangers (  page 186).
Mercedes!

A stored speed appears along with the J dis-
play.\bThe segments between the stored speed and the end of the segment display light up in the
speedometer.
System limits
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lower gear in good time on long andsteep downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so, you
will make use of the braking eMect of the engine.
This relieves the load on the brake system and prevents the brakes from overheating and wearing
too quickly.
Do not use cruise control in the following situa-
tions:
= in traPc situations which require frequent
changes of speed, e.g. in heavy traPc, on
winding roads
= on slippery roads. Accelerating can cause the
drive wheels to lose traction and the vehicle
could then skid.
= when visibility is poor

q Operating cruise control&WARNING Risk of accident due to stored
speed
If you call up the stored speed and this is
lower than your current speed, the vehicle
decelerates.
Take into account the traPc situation
before calling up the stored speed.
Requirements
= Cruise control is selected.
= ESP n
must be activated, but not intervening.
= The vehicle speed is at least 15 mph
(20 km/h).

Other features of Active Distance Assist
DISTRONIC:
= Adjusts the driving style depending on the
selected drive program (fuel-saving, comforta-
ble or dynamic)
= Initiates acceleration to the stored speed if the
turn signal indicator is switched on to change
to the overtaking lane
= Vehicles with Driving Assistance Package:
- Reacts to stationary vehicles detected in
urban speed ranges (except bicycles and
motorcycles)
- Takes one-sided overtaking restrictions
into account on highways or on multi-lane
roads with separate carriageways (coun-
try-dependent)
Vehicles with Driving Assistance Package and
Parking Package: if the vehicle has been braked to
a standstill on multi-lane roads with separate car- riageways by Active Distance Assist DISTRONIC, itcan automatically follow the vehicle in front when driving oM again within 30 seconds. If a critical sit-
uation is detected when driving oM, a visual and
acoustic warning is given indicating that the drivermust now take control of the vehicle. The vehicle
is not accelerated any further.
