Cargo compartment enlargement
Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for-
wards, e.g. when braking suddenly or in the
event of an accident.
RThe vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
RObjects or loads in the trunk/cargo com-
partment cannot be restrained by the seat
backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
!Before folding the backrest in the rear com-
partment forwards, make sure that the rear
compartment armrest and the cup holder are
folded in. They may otherwise be damaged.
Observe the loading guidelines (
Ypage 247).
The left-hand and right-hand rear seat backrests
can be folded forwards separately to increase
the cargo compartment capacity.
Notes on using the cargo compartment
Making the best use of your cargo compart-
ment:
RYou can increase the load capacity by adjust-
ing the backrest to the cargo position
(
Ypage 251).
RThe load area can be lengthened by folding
forward the folding backrest of the front-
passenger seat (
Ypage 249) and the corre-
sponding backrest in the rear.

Observe the service intervals in the Mainte-
nance Booklet or contact a qualified specialist
workshop for more information.
!You should have all work involving the bat-
tery carried out at a qualified specialist work-
shop. In the exceptional case that it is neces-
sary for you to disconnect the battery your-
self, make sure that:
Rswitch off the engine and remove the
SmartKey. On vehicles with KEYLESS-GO,
make sure that the ignition is switched off.
Check that all the indicator lamps in the
instrument cluster are off. Otherwise, elec-
tronic components, such as the alternator,
may be damaged.
Ryou first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic system
may be damaged.
Rin vehicles with automatic transmission,
the transmission is locked in position j
after the battery is disconnected. The vehi-
cle is secured against rolling away. You can
then no longer move the vehicle.
The battery and the cover of the positive ter-
minal clamp must be installed securely during
operation.
Comply with safety precautions and take pro-
tective measures when handling batteries.
Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Battery acid is caustic. Avoid contact
with skin, eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Rinse any acid spills immediately
with clear water. Contact a physician
if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the
battery be damaged in the event of an accident.
In order for the battery to achieve the maximum
possible service life, it must always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In this case, have the battery disconnected at a
qualified specialist workshop. You can also
charge the battery with a charger recommended
by Mercedes-Benz. Contact a qualified special-
ist workshop for further information.
Have the battery condition of charge checked
more frequently 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 for a long period of time.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz.
Remove the SmartKey if you park the vehicle
and do not require any electrical consumers.
The vehicle will then use very little energy, thus conserving battery power.
If the power supply has been interrupted, e.g. if
you reconnect the battery, you will have to:
Rset the clock using the multimedia system
(see the Digital Operator's Manual)
Rreset the function for folding the exterior mir-
rors in/out automatically, by folding the mir-
rors out once (
Ypage 98)
Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
290Battery (vehicle)
Breakdown assistance
GWARNING
During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks
are created, the hydrogen gas can ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on a battery.
RIt is important that you observe the described order of the battery terminals when connecting
and disconnecting a battery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting 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.
!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 in the instrument cluster 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. Let the battery thaw first. The service life of a thawed-out battery may be shorter.
The starting characteristics can be impaired, particularly at low temperatures. Have the thawed-out
battery checked at a qualified specialist workshop.
Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged, the
engine can be jump-started from another vehicle or from a second battery using jumper cables.
Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-
start the vehicle using a second battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables that are not damaged and have a sufficient cross-section and insulated terminal clamps.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RNon-insulated parts of the terminal clamps do not come into contact with other metal parts while
the jumper cables are connected to the battery.
RThe jumper cables cannot come into contact with parts that can move when the engine is running,
such as the V-belt pulley or the fan.
XSecure the vehicle by applying the electric parking brake.
XShift the transmission to position j.
XTurn the SmartKey to positiongin the ignition lock and remove it.
