2014 MERCEDES-BENZ CLS-Class jump start

over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. G
WARNING
Ad ischarged battery can freeze at
temperatures below freezin gpoint .When
jump-starting the vehicle or charging the
battery, gases can escape from the battery.
There is arisk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a
maximum charging voltage of 14.8 V.
! Only charge the battery using the jump-
startingc onnection point.
The jump-starting connection point is in the
engine compartment( Ypage 326).
X Open the hood (Y page 306).
X Connect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor
battery in the jump-starting procedure
(Y page 326).
If, at low temperatures, the indicator lamps/
warning lamps in the instrumentc luster do
not light up, it is highly likely that the
discharged battery has frozen.Int his case,
you may neither charge the battery nor jump-
start the vehicle. The service life of athawed-
out battery may be shorter. The starting
characteristics may be impaired, especiallyat
low temperatures. Have the thawed-out
battery checked at aqualified specialist
workshop.
Never charge abattery still installed in the
vehicle unless abattery charger unit
approved by Mercedes-Ben zisbeing used. A
battery charger unit speciallya dapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for further information and availability. Read the battery
charger's operating instructions before
charging the battery. Battery (vehicle)

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a
positive terminal and an earth point, in the engine compartment. G
WARNING
Battery acid is caustic. There is arisk 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
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezin gpoint .When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy startinga ttempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
Do not start the vehicle using arapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from asecond battery using jumper
cables. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using asecond battery or ajump-starting device.
R You may only jump-start th evehicl ewhen th eenginea nd exhaust system are cold.
R Do no tstart th eengineift hebattery is frozen .Let th ebattery thaw first. 326
Jump-startingBreakdown assistance

R
Only jump-start from batteries with a12Vvoltage rating.
R Only use jumper cables which have asufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected
for afew minutes before attempting to start. This charges the battery slightly.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jumper cables are not damaged.
R when the jumper cables are connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
R the jumper cables cannot come into contact with parts which can move when the engine
is running, such as the V-belt pulley or the fan.

WARNING
Function srelevant to safety are restricted or
no longer available if:
R the engin eisnot running.
R the brake system or the power steering is
malfunctioning.
R ther eisam alfunction in the voltage supply
or the vehicle's electrical system.
If your vehicle is being towed, much more
forc emay be necessary to steer or brake.
There is arisk of an accident.
In such cases, use atow bar. Befor etowing,
make sure that the steering moves freely. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towin geye could detach itself
R the vehicle/trailer combination could
rollover.
There is arisk of an accident.
When towin gortow-starting another vehicle,
its weight should not be greater than the
permissible gross weight of your vehicle.
Information on your vehicle's gross vehicle
weight ratin gcan be found on the vehicle
identification plate (Y page 372). !
If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
preven tdamage to th evehicle ,deactivate
DISTRONI CPLUS and the HOLD function in
the following or other similar situations:
R when towing the vehicle
R in the car wash
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise ,the vehicle could
be damaged.
! Do not use the towing eye for recovery,
this could damage the vehicle .Ifindoubt,
recover the vehicle with acrane.
! When towing, pulla wayslowly and
smoothly .Ifthe tractive power is too high,
the vehicles could be damaged.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! When towing vehicles with KEYLESS-GO,
use the key instead of the Start/Stop
button. Otherwise, the automatic
transmission may shift to position Pwhen
the driver's or front-passenger door are
opened, which could lead to damage to the
transmission.
! The vehicle can be towed amaximum of
30 miles (50km). The towing speed of

WARNING
If you manipulate or bridge afaulty fuse or if
you replace it with afuse with ahigher
amperage, the electric cables could be
overloaded. This could result in afire. There
is ar isk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
! Only use fuses that have been approved
for Mercedes-Ben zvehicles and which
have the correct fuse ratin gfor the system
concerned. Otherwise, componentsor
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows ,all the
component sonthecircuit and their functions
stop operating.
Blown fuse smust be replace dwith fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
If an ewly inserted fuse also blows, have the
cause traced and rectified at aqualified
specialist workshop, e.g. an authorized
Mercedes-Ben zCenter. Befor
