Notes on breaking-in a new vehicle

The sensor system of some driving and driving

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 procedure.

New and replaced brake pads and discs only

reach their optimum braking effect after several

hundred kilometers of driving. Compensate for

this by applying greater force to the brake pedal.

Driving

Important safety notes

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.

WARNING

Unsuitable footwear can hinder correct usage

of the pedals, e.g.:

shoes with thick soles

shoes with high heels

slippers

There is a risk of an accident.

Wear suitable footwear to ensure correct

usage of the pedals.

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.

WARNING

If the parking brake has not been fully

released when driving, the parking brake can:

overheat and cause a fire

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 damage, the

charging cable has been removed from the

vehicle socket. Otherwise, you cannot shift

the transmission out of position P.

The braking performance of the electric motor

using recuperative braking is, in some operating

modes, either reduced or not effective:

when the condition of charge of the high-volt-

age battery increases

if the high-voltage battery is not yet at a nor-

mal operating temperature

when driving close to the maximum speed

when the vehicle is almost stationary

in transmission position N

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, counteract 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.

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 Smart-

Key determines whether a valid SmartKey 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 approximately

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 Smart-

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:

the Start/Stop button must be inserted in the

ignition lock.

the SmartKey must be in the vehicle.

the vehicle must not be locked with the

SmartKey or KEYLESS-GO (Y page 66)

Do not keep the KEYLESS-GO key:

with electronic devices, e.g. a mobile phone

or another SmartKey.

with metallic objects, e.g. coins or metal foil.

inside metallic objects, e.g. a metal case

This can affect the functionality of KEYLESS-GO.

If you lock the vehicle with the SmartKey remote

control or with KEYLESS-GO, after a short time:

you will not be able to switch on the ignition

with the Start/Stop button.

you will no longer 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 button

on the front door (Y page 72), you can continue

to start the drive system with the Start/Stop

button.

The drive system can be switched off while the

vehicle is in motion by pressing and holding the

Start/Stop button for three seconds.

Important safety notes

WARNING

If children are left unsupervised in the vehicle,

they could:

open the doors, thus endangering other

people or road users.

get out and disrupt traffic.

operate the vehicle's equipment.

Additionally, children could set the vehicle in

motion if, for example, they:

release the parking brake.

shift the transmission out of park position P

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 vehicle is not seen by

other road users. This requires you to adopt a

particularly anticipatory 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 generator.

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 automati-

cally 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.

(Y page 152) appears in the lower part of the

multifunction display.

Starting procedure with the SmartKey

To start the drive system using the key instead

of the Start/Stop button, pull the Start/Stop

button out of the ignition lock.

Turn the SmartKey to position 3 (Y page 109)

in the ignition lock and release it.

The drive system is started. Once the vehicle

is ready to be driven, the

ReadyReady display

(Y page 152) appears in the lower part of the

multifunction display.

Pulling away

The vehicle is equipped with a sound generator.

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 automati-

cally at higher speeds.

Depress the brake pedal and keep it

depressed.

Move the DIRECT SELECT lever to position D

or R.

Release the brake pedal.

Carefully depress the accelerator pedal.

The electric parking brake is automatically

released (Y page 131).

The red F (USA only) or ! (Canada

only) indicator lamp in the instrument cluster

goes out.

The vehicle locks centrally once you have pulled

away. The locking knobs in the doors drop down.

You can open the doors from the inside at any

time.

It is only possible to move the DIRECT SELECT

selector lever from position P to the desired

selector lever position if you depress the brake

pedal. The parking lock is then deactivated and

the electrical parking brake is released auto-

matically. If the brake pedal is not depressed,

the DIRECT SELECT lever can still be moved but

the parking lock remains engaged.

Make sure that no charging cable is plugged in.

The parking lock cannot be released if a charg-

ing 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.

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:

you are pulling away on a level road or on a

downhill gradient.

the DIRECT SELECT lever is in position N.
