Changing gear
The automatic transmission shifts to the
individual gears automatically when it is in
transmission position D. This automatic
gearshifting behavior is determined by:
R the selected drive program
E/S(Y page 155)
R the position of the accelerator pedal
R the road speed Driving tips
Kickdown Use kickdown for maximum acceleration.
X
Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up. Towing a trailer X
When traveling downhill, switch to a lower
gear if the automatic transmission
constantly switches between two gears.
X Engaging a lower gear and reducing the
speed reduces the risk of the engine
overheating. Program selector button

paddle shifters (Y page 156).
i You can only change gear with the
steering wheel paddle shifters when the
transmission is in position D.Automatic drive program
Drive program Eis characterized by the
following:
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
Drive program Sis characterized by the
following:
R sporty engine and automatic transmission
settings
R the vehicle pulling away in first gear R
the automatic transmission shifting up
later
R the fuel consumption possibly being higher
as a result of the later automatic
transmission shift points
Manual drive program M General notes
In this drive program, you can briefly change
gear yourself by using the steering wheel
paddle shifters. The transmission must be in
position

limited amount of time. Depending on which
paddle shifter is pulled, the automatic
transmission immediately shifts into the next
gear down or up, if permitted.
X To shift up: pull the right-hand steering
wheel paddle shifter (Y page 156).
The automatic transmission shifts up to the
next gear.
i If the maximum engine speed on the
currently engaged gear is reached and you
continue to accelerate, the automatic

of time. Under certain conditions the
minimum amount of time is extended, e.g. in
the case of lateral acceleration, during an
overrun phase or when driving on steep
terrain.
If manual drive program Mhas been
deactivated, the automatic transmission
shifts into the automatic drive program that
was last selected, i.e. Eor S.

This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always
transmitted to both axles.
! Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact a qualified specialist
workshop for a performance test.
! To prevent ESP ®
from intervening, the
ignition must be switched off (SmartKey in
position 0or 1) if:
R the parking brake is being tested on a
brake dynamometer.
R the vehicle is being towed with only one
axle raised (not permitted for vehicles
with 4MATIC).
The brake system could otherwise be
damaged.
! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission. Refueling
