unless a child restraint system with trans-
ponders for automatic child seat recogni-
tion is fitted to the front-passenger seat. In order to make use of the automatic child
seat recognition, a Mercedes-Benz
approved child seat with a transponder is
necessary.
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the
_ PASSENGER AIRBAG ON indicator
lamp lights up for 60 seconds after the igni-
tion is switched on and the 4
PASSENGER AIRBAG OFF indicator lamp
does not light up.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed to
the side of the dashboard and on both sides of the sun visor on the front-passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre. Warning notice on the front-passenger sun visor
Warning symbol for a rearward-facing child
restraint system NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it; DEATH or SERIOUS INJURY to the
CHILD can occur. Automatic child seat recognition on
the front-passenger seat G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light up when the child
restraint system is fitted, the front-passenger front airbag has not been disabled. If the front-
passenger front airbag deploys, the child
could be seriously or even fatally injured.
Proceed as follows:
R do not use a rearward-facing child restraint
system on the front-passenger seat.
or
R only use a forward-facing child restraint
system on the front-passenger seat. Move
the front-passenger seat as far back as pos-
sible. When doing so, ensure that the shoul-
der belt strap from the belt outlet on the
vehicle is routed towards the front to the
shoulder belt guide on the child restraint
system.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. a cushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries. Child restraint systems

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. Drive sensibly – save fuel Observe the following tips to save fuel:
R The tyres should always be inflated to the
recommended tyre pressure.
R Remove unnecessary loads.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Observe the service intervals in the Service
Booklet or in the service interval display.
Have all the maintenance work carried out
in accordance with Daimler AG regulations.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic, on
short journeys and in hilly terrain. ECO display
Example: ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Con-
sumption can be significantly influenced by
your driving style.
The ECO display consists of three bars:
R Acceleration

Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Service
Booklet or contact a qualified specialist
workshop for more information.
! You should have all work involving the
battery carried out at a qualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery yourself, make sure that:
R you switch off the engine and remove the
key. On vehicles with KEYLESS-GO,
ensure that the ignition is switched off.
Check that all the indicator lamps in the
instrument cluster are off. Otherwise,
electronic components, such as the
alternator, may be damaged.
R you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
R the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be fitted securely dur- ing operation.
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Fire, naked flames and smoking
are prohibited when handling the
battery. Avoid creating sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing. Wear suitable protective clothing,
in particular gloves, an apron and a
face mask.
Immediately rinse acid splashes
off with clean water. Consult a doc- tor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at a qualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, please contact a quali- fied specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked up for a long period of time.
i When you park the vehicle, remove the
key if you do not require any electrical con- sumers. The vehicle will then use very littleenergy, thus conserving battery power. Charging the battery

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient 584

Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with water and seek medical attention. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery chargers allow the battery to be charged
while still installed in the vehicle.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
! Only
charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartment.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the
discharged battery has frozen. In this case
you may neither jump-start the vehicle nor
charge the battery. The service life of a bat-
tery that has been thawed may be reduced.
The starting characteristics may be impaired,
especially at low temperatures. Have the
thawed battery checked at a qualified spe-
cialist workshop.

vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the
discharged battery has frozen. In this case you may neither jump-start the vehicle nor charge
the battery. The service life of a battery that has been thawed may be reduced. The starting
characteristics may be impaired, especially at low temperatures. Have the thawed battery
checked at a qualified specialist workshop. 586
Jump-startingBreakdown assistance

The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
speed at which you are driving and the load on the tyres, the tyre temperature and thus the
tyre pressure changes by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres. Only correct the tyre pressure if it
is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics and thus driving safety (e.g. aqua- planing)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given for higher loads. These are permissible andwill not adversely affect the running of the
vehicle. Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of aloss of pressure, a corresponding warning
message will appear in the multifunction dis-
play.
You can recognise the tyre pressure loss
warning by the Run Flat Indicator
Run Flat Indicator active Restart with OK active Restart with OK
message which
appears in the Serv.
Serv.menu of the multifunc-
tion display. Information on the message dis- play can be found in the "Restarting the tyre
pressure loss warning system" section
(Y page 601).
Important safety notes The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (Y page 600).
The tyre pressure loss warning does not
replace the need to regularly check the tyre
pressures. An even loss of pressure on sev-
eral tyres at the same time cannot be detec-
ted by the tyre pressure loss warning system.
The tyre pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you drive with a heavy load.
