also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
The more you look after the engine when it is
new, the more satisfied you will be with its
performanc einthe future.
R Therefore, drive at varying speeds and
engine speeds for the first 1,500 km.
R Avoid heavy loads on the engine during this
period, e.g. driving at full throttle.
R Change gear in good time, at the latest
when the rev counter needle is 2
/ 3 of the
way to the red area in the rev counter dis-
play.
R Do not manually shift to alower gear to
brake the vehicle. Vehicles with automatic transmission:

If possible, do not depress the accelerator
pedal past the point of resistanc e(kick-
down).
R Only select shift ranges 3,2or 1when driv-
ing slowly, e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds.

WARNING
Do not place any object sinthe driver's foot-
well. If you use afloormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose object sorthe floormats could other-
wise get caught between the pedals if you
accelerate or brake suddenly. You will then
not be able to brake, declutch or accelerate
as intended. This could lead to accident sand
injury. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performanc euntil it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary. 146

the transmission is in position N.
R the parking brake is applied.
R ESP ®
is malfunctioning. ECO start/stop function
General notes The ECO start/stop function is only available
for the
E200 CGI BlueEFFICIENCY model with
manual transmission.
The ECO start/stop function switches the
engine off automatically in certain situations.
The engine start sautomatically when you pull
away again. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle. The ECO start/stop function is activated each
time the engine is switched on. The system is operational when ECO symbol
:is shown in
the multifunction display.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automatic engine switch-off The ECO start/stop function switches off the
engine automatically at low speeds if you:
R
apply the brake and bring the vehicle to a
standstill
R operate the clutc hpedal R
engage neutral N(follow gearshift instruc-
tion ;to engage neutral N,ifnecessary)
R release the clutc hpedal
The engine is only switched off if:
R the outside temperature is within the range
that is suitable for the system.
R the engine is at normal operatin gtemper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the batter yissufficiently charged.
R the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on.

Problem Possible causes/consequences and
M Solutions
Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop, e.g. aMercedes-Benz Service Centre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 283). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X
At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop, e.g. to aMercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission
Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
! When shifting between 5thand 6thgear,
you should always push the gear lever all the way to the right. Otherwise, you could
shift unintentionally into
3rdor4th gear
and damage the transmission.
If you shift down at too high aspeed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise arisk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing
at railer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Manual transmission

Problems with the transmission
Problem Possible causes/consequences and
M Solutions
The transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at aqualified specialist work-
shop, e.g. aMercedes-Benz Service Centre, immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into
secondgear and reverse gear.
X Stop the vehicle.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least 10 seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.
X Have the transmission checked at aqualified specialist work-
shop, e.g. aMercedes-Benz Service Centre, immediately. Releasing the parking lock manually
In the event of an electrical fault, it is possible
to release the selector lever lock manually to
move it out of position P,e.g. if you wish to
tow the vehicle away. !
Do not use any sharp-edged objectstol ift
up the selector lever cover in the centre
console. Otherwise, the selector lever
cover could be damaged.
X Engage the parking brake.
X Prise out selector lever gaiter :with aflat,
blunt object,( e.g.ascrewdriver wrappe dincloth
)from the right-hand edge, pulling it
up and out.
