IntroductionOperating your vehicle outside the USA or Canada
If you plan to operate your vehicle in foreign countries, please be aware that:
•Service facilities or replacement parts may not be readily available,
•unleaded gasoline for vehicles with catalytic converters may not be available; the use of leaded fuels will damage
the catalysts,
•gasoline may have a considerably lower octane rating, and improper fuel can cause engine damage.
Certain Mercedes-Benz models are available for delivery in Europe under our European Delivery Program. For details,
consult your authorized Mercedes-Benz Center or write to:

Engine oil level indicator

cluster displayPractical hints Car care Index One of the following messages will subsequently appear
on the indicator:
“ENGINE OIL LEVEL – O.K.”
No oil needs to be added.
“ENGINE OIL LEVEL – ADD 1.0 QUART”
(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”
(Canada: 1.5 L)
“ENGINE OIL LEVEL – ADD 2.0 QUART”
(Canada: 2.0 L)
See page246for instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The message “PERF. SERV. ON TIME” (perform service
[engine oil level check] on time) will be displayed if a
proper oil level check cannot be performed. The engine
oil level check can be repeated after a short time.Perform the engine oil level check with the dipstick, if it
cannot be completed via the multifunction display.
See page246
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.
Note:
See malfunction and warning messages on page222
and page232if an engine oil level indicator appears on
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.

Catalytic converter
Te ch n ica l

Catalytic converter
Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.Caution!
To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible 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.

Automatic transmission
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index
Press and hold selector lever in the ædirection:
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.
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.

Malfunction and warning messages

cluster displayPractical hints Car care Index
2 There is no oil in the engine. There is a danger of engine damage.
3 There is a risk of damaging the engine or catalytic converter. The
engine oil level must be checked immediately. See Engine oil level
indicator on page110.
4 The engine oil level has dropped to a critical level.
Check the engine oil level immediately. See Engine oil level
indicator on page110 and check the engine for visible leakage (loss
of oil).
5 The measuring system is malfunctioning.
6 It may be that there is water in the engine oil. Have the engine oil
che cked.
When the “ENGINE OIL LEVEL – CHECK LEVEL”
message appears while the engine is running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The engine oil level warnings should not be ignored.
Extended driving with the symbol displayed could
result in serious engine damage that is not covered by
the Mercedes-Benz Limited Warranty.

Checking engine oil level (CLK 320 shown)
1Oil dipstick
2Oil filler cap
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check engine oil level approximately 5 minutes after
stopping the engine, allowing for the oil to return to the
oil pan.Wipe oil dipstick clean prior to checking the engine oil
level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.
Oil level must be between the
lower (min) and upper (max) mark of
the dipstick.
Fill quantity between upper and lower dipstick marking
level is approximately 2.1 US qt (2.0 l).
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 page222 if
an engine oil level display appears on the multifunction
display when the engine is running.
Note:
See page110for engine oil level indicator.

Jump starting
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Important!
3. Clamp one end of the first jumper cable to the
positive (+) under hood terminal of the discharged
battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal (2) of the discharged battery.
Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter. Important!
A discharged battery can freeze at approx. +14°F
(–10°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in it exploding, causing
personal injury.
Jumper cable specifications:
•Minimum cable cross-section of 25 mm
2 or approx.
2AWG
•Maximum length of 11.5 ft. (3.5 m).
