Important safety notes G
WARNING
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 or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
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 windshield wiper arm without a wiper
blade and it falls onto the windshield/rear

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.

Important safety notes
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain 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 or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force
to the brake pedal. The first 1000 miles (1500 km)
For the service life and economy of your vehi-
cle it is crucial that you break in the engine
with due care.
R Therefore, protect the engine for the first
1000 miles (1500 km
) by driving at varying
vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g. driv-
ing at full throttle. Do not exceed Ø of the
permissible maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
i You should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced. Driving

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. 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 driv-
ing off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating 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. 126

situations:
R if you pull out the key.
R if you open the driver's door
when the vehicle is stationary or
when driving at a very low speed
and the transmission is in posi-
tion h or k.
The parking lock should not be used

The automatic transmission
changes gear itself. All forward
gears are available.
You can influence gearshifts with
your choice of drive program. You
can also restrict the shift range. Transmission position and drive pro-
gram display

current gear in drive program M
= Shift range, if restricted
The transmission positions and current drive
program : are shown at the bottom of the
instrument cluster display. The current trans-
mission position is highlighted.
In drive program M, the transmission position
indicator shows the current gear in position D
( Y page
135).
If you restrict the shift range, the transmission
position indicator shows the current transmis-
sion position plus restricted shift range =,
e.g. D2 ( Y page 133).
The arrows in the transmission position display
show how and into which transmission posi-
tions you can change using the DIRECT
SELECT lever. Changing gear
The automatic transmission adapts to your
individual driving style by continuously adjust-
ing its shift points. These shift point adjust-
ments take into account the current operating
and driving conditions. If the operating or driv-
ing conditions change, the automatic transmis-
sion reacts by adjusting the gearshift program.
When the automatic transmission is in trans-
mission position h, it shifts the individual
gears automatically.
This depends on the following factors:
R the drive program selected ( Y page 134)
R any restriction in the shift range
(Y page
133)
R the position of the accelerator pedal
R the road speed
You can also change gear manually if you
select drive program M (Y page 135).132

Shift ranges
:
To shift down and restrict the shift range
; To shift up and derestrict the shift range
In transmission position h and drive pro-
grams E and C, you can use the steering wheel
paddle shifters to change gear yourself and
restrict or derestrict the shift range of the
automatic transmission.
X To shift down and restrict the shift
range:
briefly pull left steering wheel paddle
shifter :.
The automatic transmission shifts to the
next gear down, depending on the gear cur-
rently engaged. The shift range is also
restricted.
The transmission position indicator also
shows the set shift range, e.g. D2. The auto-
matic transmission shifts only as far as the
relevant gear.
or X Pull and hold left steering wheel paddle
shifter :.
The automatic transmission will shift to a
range which allows easy acceleration and
deceleration. To do this, the automatic
transmission shifts down one or more gears
and restricts the shift range.
The transmission position indicator also
shows the set shift range, e.g. D2. The auto-
matic transmission shifts only as far as the
relevant gear.
The automatic transmission does not shift
down if you pull the left steering wheel pad-
dle shifter whilst traveling at too high a
speed. If the maximum engine speed for the
restricted shift range is reached and you
continue to depress the accelerator pedal,
the automatic transmission will shift up
automatically. This protects the engine from
overrevving. X
To shift up and extend the shift range:
briefly pull right steering wheel paddle
shifter
;.
The automatic transmission shifts to the
next gear up, depending on the gear cur-
rently engaged. This derestricts the shift
range at the same time.
If the display shows only transmission posi-
tion h, the shift range restriction is can-
celed.
X To derestrict the shift range: pull and hold
right steering wheel paddle shifter ;.
The automatic transmission shifts up one or
more gears depending on the gear currently
engaged. At the same time, the shift range
restriction is canceled and the display
shows transmission position D .
Shift ranges and driving situations =

Drive programs
General notes You can use the program selector button to
choose between different drive programs for
the automatic transmission, depending on the
engine. Engine management and the gearshift-
ing characteristics of the automatic transmis-
sion change depending on which drive pro-
gram is selected. Thus, a more comfort-orien-
ted, a more economical, or a sportier driving
style is supported, depending on the wish of
the driver. Selecting drive program M deacti-
vates automatic gearshifting, requiring that
you change gear manually.
After the engine is started, the automatic
transmission automatically switches to drive
program C (Comfort) for a comfortable and
economical driving style. Automatic transmission
133Driving and parking Z

Kickdown
Use kickdown for maximum acceleration:
X Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to the
next gear down, depending on the engine
speed.
X Ease off on the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts up again.
Rocking the vehicle free At speeds up to 5 mph (9 km/h) you can
switch back and forth between drive position
h and reverse gear
k without applying the
brakes. This helps when rocking the vehicle
out of snow or slush.
X Push the DIRECT SELECT lever alternately
up and down beyond the first point of resist-
ance.
Towing a trailer X
Depending on the downhill gradient, limit
the shift range
(Y page 133) or shift man-
ually into a lower gear (Y page 135) in which the engine will operate in the middle
of the engine speed range. This also applies
if cruise control is activated. Manual gearshifting
General notes If you select drive program
M, automatic gear-
shifting is deactivated and manual gearshifting
is automatically activated. You must then per-
manently change gear yourself for as long as
the drive program is selected.
Permanent manual gearshifting is deactivated
automatically when you switch from drive pro-
gram M to another drive program. The auto-
matic transmission then shifts gears automati-
cally. The display shows the selected drive
program and transmission position h again. Shifting gears
:
To shift down
; To shift up
The drive program display shows M and the
transmission position indicator shows the
selected gear.
X To shift up: briefly pull right-hand steering
wheel paddle shifter ;.
If the engine speed is sufficient, the auto-
matic transmission shifts up to the next
gear.
If the maximum engine speed is reached in
the currently engaged gear and you con-
tinue to accelerate, the automatic transmis-
sion will not shift up automatically. Always
make sure that the engine speed does not
reach the red area of the tachometer.
Observe the gearshift recommendation in
the display
(Y page 136). When the engine
reaches its maximum speed, the fuel supply
is cut to prevent the engine from overrev-
ving.
X To shift down: pull briefly on left-hand
steering wheel paddle shifter :.
Provided that the engine will not exceed its
maximum speed when shifting down, the
automatic transmission shifts down to the
next gear.
