aged.
If ASR is deactivated or ESP
®has
malfunctioned: only move the selec-
tor lever to Nif the vehicle is in dan-
ger of skidding, e.g. on icy roads.
7Drive
The automatic transmission changes
gear itself. All forward gears are avail-
able.
You can influence the gearshifts and
shift gears yourself or limit the shift
range.
Changing gear
The 5-speed automatic transmission adapts to
your individual driving style by continuously
adjusting its shift points. These shift point
adjustments take into account the current oper-
ating and driving conditions. If the operating or
driving conditions change, the automatic trans-
mission reacts by adjusting the gearshift pro-
gram.
When the selector lever is in position D, the
automatic transmission selects the individual
gears automatically. This depends on:
Rany restriction in the shift range
(Ypage 123)
Rthe position of the accelerator pedal
Rthe road speed
Touchshift
When the selector lever is in position D, you can
perform gearshifts yourself.
XTo shift down: press the selector lever to the
left towards D–.
The automatic transmission shifts to the next gear down, depending on the gear currently
engaged. The shift range is also restricted.
iThe automatic transmission does not shift
down if you press the selector lever towards
D– while traveling at too high a speed. This
protects the engine from overrevving.
XTo shift up: briefly press the selector lever to
the right towards D+.
The automatic transmission shifts to the next
gear up, depending on the current gearshift
program. This also extends the shift range.
XTo derestrict the shift range: press and hold

appears
in the display again.
The automatic transmission shifts from the
current shift range directly to D.
XTo select the optimum shift range: press
and hold the selector lever to the left towards
D–.
The automatic transmission will shift to a
range which allows easy acceleration and
deceleration. To do this, the automatic trans-
mission will shift down one or more gears.

Diesel Exhaust Fluid (DEF)
Important safety notes
!Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or
thin it with tap water. The exhaust gas after-
treatment may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of additives
or tap water leads to the loss of the New
Vehicle Limited Warranty.
!If DEF comes into contact with a painted or
aluminum surface, wash the surface off
immediately with plenty of water.
!DEF is not a diesel additive and must not be
mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of DEF
will not be covered by the New Vehicle Limi-
ted Warranty.
iIf the outside temperature is below 12 ‡
(Ò11 †) it may be difficult to top up. If the DEF
is frozen and there is an active warning indi- cator, topping up may not be possible. Park
the vehicle in a warm place, e.g. in a garage,
until the DEF has become liquid again. Top-
ping up is then possible again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the tank activated) and then stop the vehicle
for at least 30 seconds. The level is then
shown correctly.
