It is not recommended to park with the propulsion system running.
If the vehicle is left with the propulsion
system running, follow the proper
steps to be sure the vehicle will not move.
Post-crash label
The post-crash label is located in the
driver's door frame.
After an accident, park the vehicle
with a sufficient distance of
approx. 7.5 m to other objects.
Park on a non-flammable surface.
Call the hotline number given on the
label to get further instructions on how to handle the vehicle.
Driving and operating155The selector lever always starts from
a centre position. The selected gear
is indicated by a yellow LED on the
selector lever. After releasing the
selector lever, it will return to the centre position.
P : This position locks the front
wheels. It is the recommended
position when starting the propulsion system because the vehicle cannot
move easily.9 Warning
It is dangerous to get out of the
vehicle if the selector lever is not fully in P with the parking brake
firmly applied. The vehicle can roll.
Do not leave the vehicle when the propulsion system is running, the
vehicle may move suddenly. You
or others can be injured. To be
sure the vehicle will not move,
even if you are on even ground,
always apply the parking brake
and move the selector lever to P.
The release button is designed to
prevent inadvertent shifting out of P
unless the vehicle has been started,
the brake pedal is depressed, and the release button is pressed.
When the vehicle is stopped, press
POWER m to switch off the vehicle.
The electric drive unit will shift to P
automatically.
The vehicle will not shift into P if it is
moving too fast. Stop the vehicle and
shift into P.
To shift into P, press the P button on
the selector lever.
To shift out of P:
1. Depress the brake pedal and press the release button.
2. Shift into the desired gear.
R : Use this gear to reverse.
If the vehicle is shifted from either R
to D, or D to R while the speed is too
high, the vehicle will shift
automatically to N. Stop the vehicle
and shift again.
To shift into and out of R:
1. Bring the vehicle to a complete stop.
2. To shift into R, press the release
button and move the selector
lever forward, and then to the left. R is illuminated in red.
To shift out of R, shift into the
desired gear.Caution
Shifting into R while the vehicle is
moving forward could damage the electric drive unit. Only shift intoR after the vehicle has been
stopped.
Driving and operating157One-pedal drivingCaution
When the vehicle is operated in L
and the driver unfastens his seat
belt, the electric parking brake is
automatically applied and one
pedal driving is not possible.
With one-pedal driving, the
accelerator pedal can be used to
control the deceleration of the vehicle
down to a complete stop.
Quick releasing of the accelerator
pedal will result in aggressive
deceleration. Slow releasing of the
accelerator pedal will allow the
deceleration of the vehicle to be
adjusted as desired.
To use one-pedal driving, shift into L.
L is only selectable when the vehicle
is in D. Press the accelerator pedal to
achieve the desired speed. The
deceleration provided by one-pedal
driving provides full regenerative
braking and helps increase energy efficiency.
While driving on slopes, one-pedal
driving may not be able to bring the
vehicle to a complete stop or hold the
vehicle at a stop.
If the vehicle cannot stop on a slope
while using one-pedal driving, the
electric parking brake may be applied to hold the vehicle stationary.
To drive again, depress the
accelerator pedal, and the electric
parking brake will automatically
disengage.
One-pedal driving may become
disabled and the vehicle may
continue to creep forward, or if
stopped, may apply the electric
parking brake or shift to P.
This can be caused by the following: ● The driver's door is open.
● The driver's seat belt is unbuckled.
● The vehicle has remained stationary for 5 minutes.
● There is a problem with the propulsion system.Additional deceleration can be
achieved by using the regenerative braking paddle.
Regenerative braking 3 161.
Car wash mode This vehicle includes a car washmode that allows the vehicle to
remain in N (neutral) for use in
automatic car washes.
Car wash mode (vehicle off) - driver in vehicle
To place the vehicle in N with the
vehicle off and occupied:
1. Apply the brake pedal.
2. Shift to N.
3. Turn off the vehicle and release the brake pedal.
4. The indicator should continue to show N. If it does not, repeat steps
1-3.
The vehicle is now ready for the
car wash.
Driving and operating159ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off, the system performs a self-test which may be audible.
Control indicator u 3 79.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS
are no longer available. During
hard braking, the vehicle can nolonger be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Electric parking brake
The electric parking brake can always
be activated, even if the vehicle is
switched off.
Do not operate electric parking brake
system too often when the vehicle is
switched off as this will discharge the 12 V vehicle battery.
In case of insufficient electric power,
the electric parking brake cannot be
applied or released.
Applying when vehicle is stationary9 Warning
Pull switch m for a minimum of
1 second until control indicator m
illuminates constantly and electric
parking brake is applied 3 79 . The
electric parking brake operates automatically with adequate force.
Before leaving the vehicle, check
the electric parking brake status.

system is not operational.
Have the cause of the fault remedied by a workshop.Resetting
If b illuminates and remains
illuminated, reset the system as
follows:
1. Stop the vehicle.
2. Switch off the vehicle and wait for
15 seconds.
3. Switch on the vehicle. If b still illuminates and remains
illuminated, seek the assistance
of a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds of approx. 25 km/h
or more.
Deviations from the stored speeds may occur when driving uphill or
downhill.
Driving and operating167Exceeding the speed limit
When exceeding the limited speed
without driver input, the speed will
flash in the Driver Information Centre
and a chime sounds during this
period.
In the event of an emergency, it is possible to exceed the speed limit by
depressing the accelerator pedal
firmly nearly to the final point. In this
case no chime sounds.
Release the accelerator pedal and
the speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Deactivation of the functionality
The limited speed will be stored and
is indicated in brackets in the Driver
Information Centre. Additionally, a
corresponding message appears.
Speed limiter is deactivated, but not
switched off. Last stored speed
remains in memory for later speed
resume.Resume limit speed
Press RES/+ . The stored speed limit
will be obtained.
Switching off the system
Press L, the speed limit indication
extinguishes in the Driver Information Centre. The stored speed is deleted.
By pressing m to activate cruise
control or adaptive cruise control,
speed limiter is also deactivated and
the stored speed is deleted.
By switching off the vehicle, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.
Forward collision alert The forward collision alert may help to
avoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera system in the
windscreen to detect a vehicle
directly ahead, in your path, within a
distance of approx. 60 m.
A vehicle ahead is indicated by the
control indicator A.
If a vehicle directly ahead is
approached too quickly, a warning
chime is sounded.
Additionally, the driver is notified by a flashing red LED stripe which is
projected on the windscreen in the
driver's field of view.
A precondition is that forward collision alert is not deactivated in the vehicle
personalisation 3 91.
Activation
Forward collision alert operates
automatically above 8 km/h, if it is not deactivated in the vehicle
personalisation menu.
Driving and operating169
DeactivationThe system can be deactivated in the
personalisation menu 3 91.
The forward collision alert will be activated again with the last selected
alert sensitivity when the vehicle is
switched on next time.
General information
9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
Forward collision alert is designed to warn about vehicles only, but may
react also to other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt,
windscreen damage or affected
by foreign items, e.g. stickers
Following distance
indication
The following distance indication
displays the distance in seconds to a
preceding moving vehicle. The front
camera in the windscreen is used to
detect the distance of a vehicle
directly ahead in the vehicle's path. It
is active at speeds above 8 km/h.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre.
Select Information menu via steering
wheel buttons and press G to select
following distance indication 3 82.
The minimum indicated distance is
0.5 seconds.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- sec.
170Driving and operatingActive emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
and obstacles directly ahead, when a
collision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver is warned by the forward collision
alert 3 167 and front pedestrian
protection 3 172.
The feature uses various inputs (e.g.
camera sensor, brake pressure,
vehicle speed) to calculate the
probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
Functionality
If equipped only with front camera the
active emergency braking operates in
a forward gear above walking speed
up to 80 km/h.
A precondition is that the system is
not deactivated in the vehicle
personalisation menu 3 91.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist
● front pedestrian protection system
Brake preparation system
When approaching a vehicle ahead
or a pedestrian so quickly that a
collision is likely, the brake
preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
If equipped only with front camera the
system operates up to a speed of
80 km/h.
Emergency automatic braking
After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prevent a crash.
Depending on the situation, the
vehicle may automatically brake
moderately or hard. This front
automatic braking can only occur if a
vehicle ahead is detected, indicated
by the vehicle ahead indicator A
3 167. On vehicles with front
