frequency and infrared remote controls plus 
removable mechanical key.
The locking tabs for the mechanical key portion of 
the two electronic main keys are a different color to 
help distinguish each individual key.
•1 electronic reserve key without remote control 
functions, plus removable mechanical key.

See page 44 on how to use the electronic key together 
with the KEYLESS-GO-card.
Important!
In the case of the loss of a KEYLESS-GO-card, electronic 
keys or mechanical keys, please, contact an authorized 
Mercedes-Benz Center or call 1-800-FOR-MERCedes (in 
the USA), or 1-800-387-0100 (in Canada) as soon as 
possible to have the keys or KEYLESS-GO-card 
deactivated.
Wa r n i n g !
When leaving the vehicle always remove the 
electronic key from the starter switch and take the 
KEYLESS-GO-card (if so equipped) with you, and 
lock your vehicle. Do not leave children unattended 
in the vehicle, or with access to an unlocked 
vehicle. Unsupervised use of vehicle equipment

231 Automatic transmission
Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
slight partial throttle.Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, position “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set the parking brake in addition to shifting 
to position “P”, see page 238 for parking brake. When parked on an incline, also turn front wheel 
against curb.Wa r n i n g !
When leaving the vehicle always remove the 
electronic key from the starter switch, take the 
KEYLESS-GO-card (if so equipped) with you and 
lock the vehicle. Do not leave children unattended 
in the vehicle, or with access to an unlocked 
vehicle. Children could move the gear selector lever 
from position “P”, which could result in an 
accident or serious injury. 

234 Automatic transmission
Te ch n ica l

Press and hold selector lever in the æ direction:
The transmission will shift from the current gear 
directly to gear range “D”.
Important!
With transmission in gear range “D”, “4” or “3”, 
upshifting from 1st to 2nd to 3rd gear is delayed 
depending on vehicle speed and engine temperature. 
This allows the catalytic converter to heat up more 
quickly to operating temperatures.
During the brief warm-up period this delayed upshift 
and increased engine noise might be perceived as a 
malfunction. However, neither the engine nor 
transmission are negatively affected by this mode of 
operation.The delayed upshift is effective with vehicle speeds 
below 31 mph (50 km/h) at partial throttle and engine 
temperatures below 95°F (35°C).
To avoid overrevving the engine when the selector lever 
is moved to a lower gear range, the transmission will not 
shift to a lower gear, if the engine’s revolutions per 
minute limit would be exceeded. In this case there will 
be no downshift, even when the vehicle speed reaches 
the engine’s rpm limit of that gear, e.g. by applying the 
service brakes.
To prevent the engine from laboring at low RPM when 
driving uphill gradients or with your vehicle heavily 
loaded, the automatic transmission will downshift when 
necessary to maintain engine RPM within the best 
torque range.
Wa r n i n g !
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.

Have your vehicle winterized at your authorized 
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil 
which is not approved for winter operation. For 
viscosity (SAE/CCMC class) and filling quantity, 
see page 395.
•Check engine coolant anticorrosion/antifreeze 
concentration.
•Additive for the windshield washer and headlamp 
cleaning system: Add MB Concentrate “S” to a 
premixed windshield washer solvent/antifreeze 
which is formulated for below freezing 
temperatures, see page 334.•Test battery: Battery capacity drops with decreasing 
ambient temperature. A well charged battery helps 
to ensure that the engine can be started, even at low 
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on 
all four wheels for the winter season. Observe 
permissible maximum speed for M+S rated 
radial-ply tires and the legal speed limit.
In winter operation, the maximum effectiveness of the 
ABS and ESP can only be achieved with M+S rated 
radial-ply tires and/or snow chains recommended by 
Mercedes-Benz. Snow chains maximize performance.

Brake assist system (BAS)
The BAS is designed to maximize the vehicle’s braking 
capability during emergency braking maneuvers by 
having maximum power boost applied to the brakes 
more quickly in emergency braking conditions than 
might otherwise be afforded solely by the driver’s 
braking style. This can help reduce braking distances 
over what ordinary driving and braking style might do. 
The BAS complements the antilock brake system (ABS).Applying the brakes very quickly results in maximum 
BA S  a ssistance.
To receive the benefit of the system you must apply 
continuous full braking power during the stopping 
sequence. Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivated.
If the BAS warning message is displayed, a malfunction 
has been detected in the system. The brake system 
functions in the usual manner, but without BAS.
With the ABS malfunctioning, the BAS is also switched 
off.
If a BAS warning message is displayed, have the BAS 
checked at your authorized Mercedes-Benz Center as 
soon as possible.
Wa r n i n g !
BAS cannot prevent the natural laws of physics 
from acting on the vehicle, nor can it increase 
braking efficiency beyond that afforded by the 
condition of the vehicle brakes and tires or the 
traction afforded. The BAS cannot prevent 
accidents, including those resulting from excessive 
speed in turns, following another vehicle too 
closely, or aquaplaning. Only a safe, attentive, and 
skillful driver can prevent accidents. The 
capabilities of a BAS equipped vehicle must never 
be exploited in a reckless or dangerous manner 
which could jeopardize the user’s safety or the 
safety of others.
