Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood/tailgate if a wiper
arm has been folded away from the wind-
shield/rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the wiper arm without a wiper blade and it
falls onto the windshield/rear window, the
windshield/rear window may be damaged
by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
!To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.

ception of the perfume intensity:
Roperating mode of the climate control sys-
tem
Rinterior temperature
Rtime of year or day
Rair humidity
Rphysiological condition of occupants, e.g.
fatigue or hunger
The perfume atomizer can only be operated
when the climate control system is switched on and is only active when the glove box is
closed.
The perfume atomizer is provided with a pre-
filled perfume vial. You can also choose from
a variety of filled perfume vials and an empty
vial which you can fill yourself.
If you refill an empty perfume vial, observe the
separate information sheet attached to the
vial.
!If you do not use genuine Mercedes-Benz
interior perfumes, observe the manufactur-
ers' safety notices on the perfume packag-
ing.

GWARNING
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.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Do not warm up the engine with the vehi-
cle stationary. Drive off immediately. Avoid
high engine speeds and driving at full throt-
tle until the engine has reached its operat-
ing temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.

General notes
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 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.

Driving and parking

ANeutral
Do not shift the transmission toN
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brake pedal will allow
you to move the vehicle freely, e.g. to push it or tow it.
If ESP
®is deactivated or faulty:
shift the transmission to position N
if the vehicle is in danger of skid-
ding, e.g. on icy roads.
If you switch the engine off with the
transmission in position Ror D, the
automatic transmission shifts to N
automatically.
!Rolling in neutral Ncan damage
the drive train.
7Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Driving tips
Changing gear
The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. This automatic gear shift-
ing behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto- matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch func-
tion is active regardless of the currently selec-
ted drive program. The double-clutch function
reduces load change reactions and is condu-
cive to a sporty driving style. The sound gen-
erated by the double-clutch function depends
on the drive program selected.
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free
Rocking the vehicle free by shifting back and
forth between transmission positions Dand R
can help to free a vehicle that has become
stuck in mud or snow.
The vehicle's engine management restricts
switching between transmission positions D
and Rto speeds up to a maximum of 5 mph
(9 km/h).
To shift back and forth between transmission
positions Dand R, move the DIRECT SELECT
lever up and down past the point of resist-
ance.
Towing a trailer
XDrive in the middle of the engine speed
range on uphill gradients.
XManual shifting: depending on the uphill
or downhill gradient, shift into a gear
(
Ypage 167), in which the engine will run
the middle of the engine speed range.
This also applies if cruise control or
DISTRONIC PLUS is activated.
