Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 25). Notes on breaking-in a new vehicle
The sensor system of some driving and driv-
ing safety systems adjusts automatically
while a certain distance is being driven after
the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in proce-
dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on
top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Before driving away, you must ensure
that, for your own safety and to avoid dam-
age, the charging cable has been removed
from the vehicle socket. Otherwise, you
cannot shift the transmission out of posi-
tion P.
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
R when the condition of charge of the high-
voltage battery increases
R if the high-voltage battery is not yet at a
normal operating temperature
R when driving close to the maximum speed
R when the vehicle is almost stationary 130

R
in transmission position N
R during and after ESP stability control
If you do not make an additional effort to
apply the brake yourself, the braking effect
may not be sufficient. If necessary, counter-
act the reduced regenerative braking effect
by applying the brake yourself.
Before commencing your journey, ensure that the charging cable required for charging the
high-voltage battery is in the vehicle. Key positions

i The SmartKey can be turned in the igni-
tion lock even if it is not the correct Smart- Key for the vehicle. The ignition is not
switched on. The drive system cannot be
started.
Start/Stop button General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS- GO function and a detachable Start/Stop but-
ton. A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example,
when starting the drive system.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately two seconds recognition time. You
can then use the Start/Stop button.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the drive system starts
immediately.
To start the vehicle without actively using the SmartKey:
R the Start/Stop button must be inserted in
the ignition lock.
R the SmartKey must be in the vehicle.
R the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 73).
Do not keep the KEYLESS-GO key:
R with electronic devices, e.g. a mobile
phone or another SmartKey.
R with metallic objects, e.g. coins or metal
foil.
R inside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-
GO.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
R you will not be able to switch on the ignition
with the Start/Stop button.
R you will not be able to start the drive system
with the Start/Stop button until the vehicle is unlocked again.
If you lock the vehicle centrally using the but-
ton on the front door (Y page 80), you can
continue to start the drive system with the
Start/Stop button. Driving

WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment. 132
DrivingDriving and parking

Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the transmission out of park position P
R start the vehicle's drive system.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your vehicle may not be heard by other road users
in certain situations. This can happen, for
example, when you are parking and your vehi-
cle is not seen by other road users. This
requires you to adopt a particularly anticipa-
tory driving style, as it is necessary to allow
for the possibility that other road users may
behave erratically.
The vehicle is equipped with a sound gener-
ator. The sound generator is activated so that
other road users can hear your vehicle better. The sound generator is activated at speeds of under 20 mph (30 km/h) and switches off
automatically at higher speeds.
Starting procedure with the Start/Stop button The Start/Stop button can be used to start
the vehicle manually without inserting the
SmartKey into the ignition lock. The Start/
Stop button must be inserted in the ignition
lock and the SmartKey must be in the vehicle.
You can start the drive system if a valid key isin the vehicle. Switch off the drive system and
always take the key with you when leaving the vehicle, even if you only leave it for a short
time. Pay attention to the important safety
notes. X

The vehicle is equipped with a sound gener-
ator. At low speeds, an electric vehicle makes less noise than a vehicle with a combustion
engine. The sound generator is activated so
that other road users can hear your vehicle
better. The sound generator is activated at
speeds of under 20 mph (30 km/h) and
switches off automatically at higher speeds.

engaged.
Make sure that no charging cable is plugged
in. The parking lock cannot be released if a
charging cable is plugged in. Hill start assist
Hill start assist will aid you when pulling away
on a hill. It holds the vehicle for a short time
after you have removed your foot from the
brake pedal. This gives you enough time to
move your foot from the brake pedal to the
accelerator pedal and depress it before the
vehicle begins to roll. G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if: R you are pulling away on a level road or on a
downhill gradient.

Driving tips
Holding the vehicle stationary on uphill
gradients Do not hold the vehicle stationary on uphill
gradients by depressing the accelerator
pedal. Instead, only ever hold the vehicle sta-
tionary on uphill gradients by:
R depressing the brake pedal
R engaging the electric parking brake
Kickdown Use kickdown for maximum acceleration.
X Depress the accelerator pedal beyond the
pressure point.
The needle in the power display points to
the boost area (Y page 183).
X Ease off the accelerator pedal once the
desired speed is reached.
i Maximum acceleration is available for a
limited time.
Rocking the vehicle free Shifting the transmission repeatedly between
gears Dand Rmay help to free the vehicle if it
has become stuck in slush or snow. The vehi- cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when shifting back and forth. To shift back and forth

+
You can increase or reduce recuperation in
overrun mode using the steering wheel pad-
dle shifters. When you remove your foot from
the accelerator pedal, recuperation occurs.
The electric motor is then used as a alternator and energy is recovered while driving. The
recuperated electrical energy is stored in the
high-voltage battery. A higher energy recu-
peration level means that the vehicle is
braked more powerfully.
If necessary, counteract the reduced regen-
erative braking effect by applying the brake
yourself.
