X Drive off carefully. Effect
B
Park position
Shift the automatic transmission
into park position P only when the
vehicle is stopped. The park position
is not intended to serve as a brake
when the vehicle is parked. Rather,
the driver should always engage the
electronic parking brake in addition
to shifting the automatic
transmission into park position
P to
secure the vehicle.
If the vehicle’s electrical system is
malfunctioning, the automatic
transmission could remain locked in
park position P.
X Have the vehicle’s electrical
system checked at an authorized
Mercedes-Benz Center as soon as
possible. C
Reverse gear

into reverse gear R only when the
vehicle is stopped.294

Effect
A
Neutral position
No power is transmitted from the
engine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the
transmission, never shift the
automatic transmission into neutral
position N while driving.
Exception: If the ESC is switched off
or malfunctioning, shift the
automatic transmission into neutral
position
N if the vehicle is in danger
of skidding.
! Coasting the vehicle, or driving
for any other reason with the
automatic transmission in neutral
position N can result in
transmission damage that is not
covered by the Mercedes-Benz
Limited Warranty. 7

The automatic transmission shifts
automatically. All forward gears are
available.
Driving tips
Kickdown Use the kickdown when you want maximum
acceleration.
X
U.S. vehicles except AMG vehicles:
Fully depress the accelerator pedal.
Depending on the engine speed the
automatic transmission shifts into a lower
gear.
X Canada vehicles and AMG vehicles:
Depress the accelerator pedal past the
point of resistance.
Depending on the engine speed the
automatic transmission shifts into a lower

R can help free a vehicle
stuck in mud or snow. The engine control
system of this vehicle electronically limits
directly shifting the automatic transmission
between drive position D and reverse gear R
to very low speeds, i.e. approximately 5 mph
(9 km/h). To shift the automatic transmission
directly between drive position D and reverse
gear R, move the gear selector lever up or
down past the resistance point.
Working on the vehicle G
Warning!
When working on the vehicle, engage the
electronic parking brake and shift the
automatic transmission into park position P.
Otherwise the vehicle could roll away which
could result in an accident and/or serious
personal injury. Gear ranges
With the automatic transmission in drive
position D and driving in automatic program
mode C or S, you can limit or extend the gear
range, see “One-touch gearshifting”

Selecting program mode C means:
R
The vehicle starts out more gentle, both
forward and reverse, except when driving
off with full throttle.
R Traction and driving stability are improved
on icy roads.
R Upshifts occur earlier even when you give
more gas. The engine then operates at
lower revolutions and the wheels are less
likely to spin.
Selecting program mode S means that
upshifts occur later. One-touch gearshifting
With the automatic transmission in drive
position D and driving in automatic program
mode C or S, you can limit or extend the gear
range using the steering wheel gearshift
control.
AMG vehicles: For information on using the
steering wheel gearshift control in manual
program mode M, see “Manual shift program”
(Y page 298). Steering wheel gearshift control (example

Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
X Briefly pull left gearshift control :.
The automatic transmission will shift into
the next lower gear as permitted by the
shift program. This action simultaneously
limits the gear range of the automatic
transmission.
i To avoid overrevving the engine when
downshifting, the automatic transmission
will not shift into a lower gear if the engine’s
maximum speed would be exceeded.
Extending gear range X
Briefly pull right gearshift control ;.
The automatic transmission will shift into
the next higher gear as permitted by the
shift program. This action simultaneously
extends the gear range of the automatic
transmission.
i If you press on the accelerator pedal
when the engine has reached the
revolution limit of the current gear range,
the automatic transmission will upshift
beyond any gear range limit selected.
Canceling gear range limit X

Upshifting !
In manual program mode M, the
automatic transmission will not upshift,
even if the engine has reached its
overrevving range. Shift up into the next
gear before the engine has reached its
overrevving range. Make absolutely certain
that the engine speed does not reach the
red marking on the tachometer. Otherwise
the engine could be damaged which is not
covered by the Mercedes-Benz Limited
Warranty.

Driving characteristics may be impaired.
If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-

Warning!
Driving when your engine is overheated can

Steam from an overheated engine can cause
serious
burns
which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†), i.e close to the
red zone of the temperature gauge.
! Excessive coolant temperature triggers a
warning in the multifunction display.
The engine should not be operated with a
coolant temperature above 248‡ (120†),
i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty. Tachometer
The red marking on the tachometer
(Y page
29) denotes excessive engine speed.
! Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
To help protect the engine, the fuel supply is
interrupted if the engine is operated within
the red marking. Outside temperature indicator
The outside temperature indicator is on the
bottom left-hand side of the instrument
cluster (Y page 29). G
Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose. Indicated temperatures just above the
freezing
point
do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster
(Y page 29). Once the fuel
level has fallen below the reserve mark, the
yellow segment indicator for the fuel reserve
comes on. Driving systems
