409 Controls in detail
Driving and parking
The engine does not start. You cannot
hear the starter.
The battery may not be sufficiently
charged.
Have the vehicle jump-started
(page 707).
If the engine will not start despite a jump
start:

Call Roadside Assistance.

Contact an authorized Mercedes-Benz
Center or call Roadside Assistance.
Driving off
Depress the brake pedal.
The gear selector lever can now be
used.

Shift the automatic transmission to
drive positionD or reverse gearR.

Release the brake pedal.

Carefully depress the accelerator
pedal.
The electronic parking brake is auto-
matically released (
page 412).
The red brake warning lamp 0
(USA only) or ! (Canada only) in the
instrument cluster goes out.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
i
Wait for the gear selection process to com-
plete before setting the vehicle in motion.
i
Shifting from park position P to reverse
gearR, neutral positionN, or drive positionD is
only possible with the brake pedal depressed.
Without the brake pedal depressed, the gear se-
lector lever can be moved, but the parking pawl
remains engaged, not allowing shifting to occur.
!
If you hear a warning signal, the red indica-
tor lamp 0 (USA only) or ! (Canada only)
in the instrument cluster flashes and the mes-
sage “Please Release Parking Brake” appears in
the multifunction display when driving off, you
are driving with the electronic parking brake en-
gaged, or you are carrying out an emergency
brake application with the electronic parking
brake.
Release the electronic parking brake
(
page 412).
i
Once the vehicle is in motion, the automatic
central locking system engages and the locking
knobs in the doors move down.
The automatic door lock feature can be deacti-
vated (page 263).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.

Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be op-
erating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Give very little gas.

Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.

Stop the vehicle in a safe location as
soon as possible and turn off the en-
gine. Allow engine and coolant to cool
off.

Check the coolant level and add cool-
ant if necessary (
page 559).In case of accident
If the vehicle is leaking gasoline:

Do not start the engine under any cir-
cumstances.

Move away from vehicle.

Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:

Contact an authorized Mercedes-Benz
Center or call Roadside Assistance.
If no damage can be determined on the


major assemblies


fuel system


engine mount:

Start the engine in the usual manner.
i
To signal minor directional changes such as
changing lanes, press combination switch only
to point of resistance and release. The corre-
sponding turn signals will flash three times.
i
Excessive coolant temperatures trigger a
warning message in the multifunction display
(
page 622).

417 Controls in detail
Automatic transmission
Automatic transmission
For more information on driving with an
automatic transmission, see “Driving and
parking” (
page 406).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.

right of the steering column.Gearshift pattern for automatic

i
During the brief warm-up, transmission
upshifting is delayed. This allows the catalytic
converter to heat up more quickly to operating
temperature.
Warning!
G
Make sure that absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.

548 OperationDriving instructionsCatalytic converter
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined in your Maintenance Booklet.
Emission control
Certain parts of the engine and the emis-
sion control system serve to keep the toxic
components of the exhaust gases within
permissible limits required by law.
These systems will function properly only
when maintained strictly according to fac-
tory specifications. Any adjustments on
the engine should, therefore, be carried
out only by qualified Mercedes-Benz Cen-
ter authorized technicians.
Engine adjustments should not be altered
in any way. The specified service proce-
dures must be carried out regularly accord-
ing to Mercedes-Benz servicing
requirements. For details please refer to
the Maintenance Booklet.
!
To prevent damage to the catalytic convert-
ers, only use premium unleaded gasoline in this
vehicle.
Any noticeable irregularities in engine operation
should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic con-
verter, causing it to overheat and potentially
start a fire.
Warning!
G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble materials such as grass, hay or leaves
can come into contact with the hot exhaust
system, as these materials could be ignited
and cause a vehicle fire.

672 Practical hintsWhat to do if …?Display
Possible cause/consequence
Possible solution
Engine Oil Level
Cannot Be
Measured
CL 600 and CL 65 AMG only:
The measuring system is malfunctioning.

Have the measuring system checked by an
authorized Mercedes-Benz Center.
Engine Oil
Level Too High
CL 600 and CL 65 AMG only:
You have added too much engine oil.
There is a risk of damaging:

the engine


the catalytic converter

Have excess oil siphoned or drained off.
Contact an authorized Mercedes-Benz
Center.

707 Practical hints
Jump starting
Jump starting
If the starter battery is discharged, the en-
gine can be started with jumper cables and
the battery of another vehicle. Observe the
following:

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.


Do not start the engine if the battery is
frozen. Let the battery thaw out first.


Only use 12-volt battery to jump start
your vehicle. Jump starting with a high-
er voltage battery could damage the ve-
hicle’s electrical system, which will not
be covered by the Mercedes-Benz Lim-
ited Warranty.


Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.


Always make sure that the jumper ca-
bles are not on or near pulleys, fans or
other parts that move when an engine
is started or running.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!
Do not tow-start the vehicle.
!
Jump starting should only be performed on
the starter battery installed in the engine com-
partment.
Avoid repeated and lengthy starting attempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the catalyt-
ic converter and may present a fire risk.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still at-
tached to a battery.
