Driving and parking

Restricting the shift range
X
Pull the left-hand steering wheel paddle
shifter.
The automatic transmission shifts down
one gear and restricts the
shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the
automatic transmission protects against
engine damage by not shifting down.
i If the maximum engine speed

for the shift
range is reached and you continue to
accelerate, the automatic transmission
shifts up, even if the shift range is
restricted. This prevents the engine from
overrevving.
Extending the shift range X
Pull the right-hand steering wheel paddle
shifter.
The shift range is derestricted.
Clearing the shift range restriction X
Pull and hold the right-hand steering wheel
paddle shifter until D is

shown again in the
multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range X
Pull the left-hand steering wheel paddle
shifter and hold it in position.
The automatic transmission shifts to the
gear which allows optimum acceleration
and deceleration. To do this,

the automatic
transmission shifts down one or more
gears. Automatic transmission

DEF (BlueTEC vehicles only)
Important notes on use To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the
reducing agent DEF. Adding
DEF
is one of the
tasks performed during maintenance. Under
normal operating conditions, a tank of DEF
lasts until the next service due date.
When the supply of DEF is almost used up,
the Check Additive See Operator's
Manual message is shown in the
multifunction display.
When the DEF supply drops to a minimum, the
Remaining Starts: 16 message is shown
in the multifunction display.
If the Remaining Starts: 16 message
appears in the multifunction display, you can
start the engine another 16 times. If DEF is
not refilled, you will subsequently be unable
to start the engine . Refill the DEF tank with
around 1 gal (3.8 l) of DEF or have the DEF
tank refilled at a qualified specialist
workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. Contact
a qualified specialist workshop with any
questions or, if necessary, contact Roadside
Assistance ( Y page 24).
If the outside temperature is below 12 ‡
(00FC11 †) it may be difficult to top up. If DEF is
frozen and there is an active warning
indicator, it may not be possible to add DEF.
Park the vehicle in a warmer place, e.g. in a
garage, until DEF has become fluid again. It
will then be possible to add DEF again.
Alternatively, have the DEF tank refilled at a
qualified specialist workshop.
Further information about BlueTEC exhaust
gas aftertreatment and DEF is available at any
authorized Mercedes-Benz Center. Important safety notes on the refilling
procedure DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R
not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may
be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may
experience a burning sensation in your eyes,
nose and throat. Coughing and watering of
the eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well-ventilated areas.
DEF must not come into contact with your
skin, eyes or clothing and must not be
swallowed. Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the following:
R Rinse DEF from your skin immediately with
soap and water.
R If DEF comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If DEF has been swallowed, rinse your
mouth out immediately. Drink plenty of
water. Seek medical assistance without
delay.
R Change out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas
aftertreatment system.
! Rinse surfaces that have come into
contact with DEF immediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clean it. DEF 158
