MSolutions The steering wheel
heating has switched
off prematurely or can-
not be switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.

When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in and out of your vehicle easier.

Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened or the SmartKey is removed from the ignition lock. This makes it easier to exit the
vehicle and rescue the occupants.

only operational if the EASY-EXIT/ENTRY fea-
ture is activated in COMAND (see the sepa-
rate operating instructions). Mirrors

Important safety notes G
WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. 140

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.

General notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Driving abroad
Symmetrical low-beam headlamps Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country where the vehicle is registered. This prevents
glare to oncoming traffic. When using sym-
metrical lights, the edge of the road is not lit
as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Asymmetrical low beam Have the headlamps converted back to asym-
metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after
crossing the border again. Setting the exterior lighting

If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
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 engine.
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 91).
Do not keep the SmartKey:
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 the Smart- Key.
Do not keep the SmartKey in the tempera-
ture-controlled cup holder (Y page 380). Oth-
erwise, the SmartKey will not be detected,
e.g. when starting the engine with the Start/ Stop button.
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 engine 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 97), you can
continue to start the engine with the Start/
Stop button. The engine can be turned off while the vehicle
is in motion by pressing and holding the
Start/Stop button for approximately three
seconds. This function operates independ-
ently of the ECO start/stop automatic engine switch-off function.

Important safety notes G
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.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine.
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. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
! Do not depress the accelerator when
starting the engine. Driving

General notes
During a cold start, the engine runs at higher
speeds to enable the catalytic converter to
reach its operating temperature. The sound of the engine may change during this time.

Starting procedure with the SmartKey To start the engine using the SmartKey
instead of the Start/Stop button, pull the
Start/Stop button out of the ignition lock.
X Turn the SmartKey to position 3in the igni-
tion (Y page 189) lock and release it as
soon as the engine is running.
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. This mode for starting the engine operates
independently of the ECO start/stop auto-
matic engine start function.
You can start the engine if a valid SmartKey is
in the vehicle. Always take the SmartKey with you when leaving the vehicle, even if you only
leave it for a short time. Pay attention to the
important safety notes.
X Depress the brake pedal and keep it
depressed.
X Press the Start/Stop button once
(Y page 189).
The engine starts. Pulling away
General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pull-
ing away.
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.
You can also deactivate the automatic locking feature (Y page 98).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the
parking lock released. If the brake pedal is not
depressed, the DIRECT SELECT lever can still be moved but the parking lock remains
engaged.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on the automatic release of the
electric parking brake (Y page 222).
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. 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 to depress it before the vehicle begins to
roll. 192
