Press switch on symbol “W”. The vehicle starts
out in 2nd gear, except with selector lever in 1st
gear, or with accelerator pedal in kick-down
position.
The “W” mode helps to improve traction and
driving stability of the vehicle.
The gear shifting process occurs at lower vehicle
and engine speeds than in the “S” program mode.
Caution!
Never change the program mode when the selector lever
is out of position “P”. It could result in a change of
driving characteristics for which you may not be
prepared.
Important!
Always be certain of the program mode selected since
the vehicle driving characteristics change with the
selection of the program mode.
Dependent on the program mode selector switch
position “S” or “W” and the gear selector lever in
position “R”, the ratio of power transmission changes.Emergency operation
(Limp home mode)
If vehicle acceleration worsens or the transmission no
longer shifts, the transmission is most likely operating
in Limp Home Mode which engages when there is a
malfunction of the transmission. This condition may be
accompanied by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster coming on.
In this mode only the 2nd gear or reverse gear can be
activated.
To engage 2nd gear or reverse:
1. Sto p t h e v e h i c l e .
2. Move selector lever to position “P”.
3. Turn off the engine.
4. Wait approx. 10 seconds.
5. Restart the engine.
6. Move selector lever to position “D” (for 2nd gear), or
move selector lever to position “R” (for reverse gear).
Have the transmission checked at your authorized
Mercedes-Benz Center as soon as possible.

Deep water
Caution!
Do not drive through flooded areas or water of unknown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.Passenger compartment
Wa r n i n g !
Always fasten items being carried as securely as
possible.In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle, and cause injury to vehicle
occupants unless the items are securely fastened in
the vehicle.The trunk is the preferred place to carry objects.

Notes:
If the engine does not brake the vehicle sufficiently
while driving on a downgrade, the speed you set on the
cruise control may be exceeded. In this case the
automatic transmission shifts down (max. to 3rd gear)
to maintain the set cruise control speed by using the
engine’s braking power.
As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position.
Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control
is switched off.
Use the lever to resume the previously set speed.
The “CRUISE CONTROL - - -” message is displayed on
the multifunction display when any attempt is made to
store speeds below 25 mph (40 km/h) or when an
attempt is made to recall a speed when no speed has
been stored – the cruise control remains switched off.
See malfunction and warning messages on page 297 if
the cruise control has a malfunction.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.
• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.

The distance warning sound continues until the driver
activates the brake pedal, or the preset distance is
obtained. As soon as the preset distance is obtained, the
distance warning lamp goes out.Caution!
If the driver’s foot is not fully removed from the
accelerator pedal, the Distronic control system will be
overridden and it will not regulate the preset vehicle
speed and following distance. The vehicle speed and
following distance is determined only by the accelerator
pedal position.
Distronic works on steep uphill and downhill gradients
by downshifting gears and applying the brakes to
maintain the speed selected by the driver. The
transmission will upshift again once the gradient evens
out.
The speed can be increased (e.g. for passing) by using
the accelerator. After the accelerator is released, the
previously set speed will be resumed automatically.
Distronic is deactivated if a vehicle in front causes your
vehicle to slow down to less than approx. 25 mph
(Canada: 30 km/h). A signal sounds and the message
“DTR OFF” appears for 5 seconds in the multifunction
display.
Wa r n i n g !
A continuous warning sounds and the distance
warning lamp in the speedometer dial is
illuminated if the Distronic system calculates that
the distance to the vehicle ahead and your vehicle’s
current speed indicate that Distronic will not be
capable of slowing the vehicle sufficiently to
maintain the preset following distance, which
creates a danger of a collision.Immediately brake the vehicle to increase the
distance to the vehicle in front of you. The warning
sound is intended as a final caution that you have
not interceded with your own braking inputs to
avoid a potentially dangerous situation. Do not wait
for the operation of the warning signal to intercede
with your own braking as that will result in
potentially dangerous emergency braking which
will not always result an impact being avoided.Tailgating increases the risk of an accident.

ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in starter switch position 2
and should go out with the engine running.
When the ABS malfunction indicator lamp symbol and
warning in the instrument cluster remains illuminated
while the engine is running, it indicates that the ABS
has detected a malfunction and has switched off. In this
case, the brake system functions in the usual manner,
but without antilock assistance.
A malfunctioning ABS control unit can possibly affect
the operation of other systems (e.g. Parktronic,
Navigation, Automatic transmission). Be guided
accordingly with respect to the use of those systems and
have the system checked at your authorized
Mercedes-Benz Center as soon as possible.With the ABS malfunctioning, the BAS and ESP are also
switched off. The malfunction indicator lamps and
malfunction messages in the multifunction display
come on with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page 269 for notes on antilock brake system (ABS).

The engine oil level can be checked by either the oil
dipstick or via the multifunction display in the
instrument cluster, see page 154.
Wipe the oil dipstick clean prior to checking the engine
oil level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.
The oil level must be between the lower
mark (min) and the upper mark (max)
on the oil dipstick.
Unscrew the oil filler cap and add oil carefully if you
need to top up the oil.
CL 500 and CL 55 AMG:
Fill quantity between upper and lower dipstick marking
level is approximately 2.1 US qt (2.0 l).
CL 600:
Follow the message appearing on the engine oil level
indicator display (page 154) as to quantity to be added.
Re-install oil filler cap.
Do not overfill the engine.
Excessive oil must be drained
or siphoned. It could cause damage to engine and
catalytic converter not covered by the Mercedes-Benz
Limited Warranty.See malfunction and warning messages on page 297 if
an engine oil level display appears on the multifunction
display when the engine is running.
Note:
See page 154 for engine oil level indicator.
Automatic transmission fluid level
The transmission has a permanent fill of automatic
transmission fluid.
Regular automatic transmission fluid level checks and
changes are not required. For this reason the dipstick is
omitted.
If you notice fluid leaks or gear shifting malfunctions,
have your authorized Mercedes-Benz Center check the
transmission fluid level.
Active body control (ABC) fluid level
Regular fluid level check is not required.
If you notice fluid leaks or malfunctions, have your
authorized Mercedes-Benz Center check the
ABC-system.

353 Towing the vehicle
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index We recommend that the vehicle be transported using
flat bed equipment. This method is preferable to other
types of towing.
Important!
To prevent damage during transport, do not tie down
vehicle by its chassis or suspension parts.
The vehicle may be towed with all wheels on the ground
and the selector lever in position “N” for distances up to
30 miles (50 km) and at a speed not to exceed 30 mph
(50 km/h). The electronic key must be in starter switch
position 2.
To be certain to avoid a possibility of damage to the
transmission, however, we recommend the drive shaft
be disconnected at the rear axle drive f lange for any
towing beyond a short tow to a nearby garage.
Do not tow with sling-type equipment. Towing with
sling-type equipment over bumpy roads will damage
radiator and supports.
Use wheel lift, dolly, or flat bed equipment, with
electronic key in starter switch turned to position 0.Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in starter switch to
position 2 and activate combination switch for left or
right turn signal in usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in starter switch
position 0 or 1). Otherwise, the ESP will immediately be
engaged and will apply the rear wheel brakes.
Switch off the tow-away alarm (see “VEHICLE” under
“Individual settings” on page 144) as well as the ESP
(see page 273).
Wa r n i n g !
With the engine not running, there is no power
assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to
brake and steer the vehicle.
