jump start MERCEDES-BENZ CLS-Class 2017 W218 User Guide

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.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connected for
a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rwhen the jumper cables are connected to the battery, uninsulated sections of the terminal clamp
do not come into contact with other metal sections.
Rthe 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.
XApply the parking brake firmly.
XShift the transmission to position P.
XMake sure that the ignition is switched off. All indicator lamps in the instrument cluster must be
off. When using the SmartKey, turn the SmartKey to position 0in the ignition lock and remove it
(
Ypage 123).
XSwitch off all electrical consumers, e.g. rear window defroster, lighting, etc.
XOpen the hood.
Position number Bidentifies the charged battery of the other vehicle or an equivalent jump-starting
device.
XSlide cover :of positive terminal ;in the direction of the arrow.
XConnect positive terminal ;on your vehicle to positive terminal =of donor battery Busing the
jumper cable, always begin with positive terminal ;on your own vehicle first.
XStart the engine of the donor vehicle and run it at idling speed.

XConnect negative terminal?of donor battery Bto ground point Aof your vehicle using the
jumper cable, connecting the jumper cable to battery of other vehicle Bfirst.
XStart the engine.
XBefore disconnecting the jumper cables, let the engine run for several minutes.
XFirst, remove the jumper cables from ground point Aand negative terminal ?, then from pos-
itive clamp ;and positive terminal =. Begineach time at the contacts on your own vehicle first.
XClose cover :of positive clamp ;after removing the jumper cables.
XHave the battery checked at a qualified specialist workshop.
Jump-starting isnot cons idered to bea normal operating condition.
iJumper cables and further information regarding jump-starting can beobtained at any qualified
specialist workshop.
Towing and tow-starting
Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer availab leif:
Rthe engine isnot running.
Rthe brake system or the power steering is
malfunctioning.
Rthere isa malfunction inthe voltage supply
or the veh icle's electrical system.
If your veh icle is bein g towed, much more
force may benecessary to steer or brake.
There isa risk of an acc ident.
In such cases, use a tow bar. Before to wing,
make sure that the steering moves freely.
GWAR NING
When to wingor tow-starting another veh icle
and its weight isgreater than the permis sible
gross weight of your veh icle, the:
Rthe to wingeye could detach itself
Rthe veh icle/trailer co mbination could roll-
over.
There isa risk of an acc ident.
When to wingor tow-starting another veh icle,
its weight should not begreater than the per-
mis sible gross weight of your veh icle.
Details on the permis siblegross veh icleweight
of your veh iclecan befound on the veh icle iden-
tification plate (
Ypage 322).
!When Active Brake Assist, Distance Pilot
DI ST RONIC or the HOLD function isactivated,
the vehicle brakes automatically incertain
situations.
To avoid damage to the vehicle, deactivate
these systems inthe following or similar sit-
uations:
Rwhen towing the vehicle
Rin 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, th is
could damage the vehicle. If indoubt, recover
the vehicle with a crane.
!When towing, pull away slowly 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 /S top button.
Otherwise, the automat ictransmission 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 betowed a maximum of
30 mile s (50km). The towing speed of 30 mph
(50 km/ h)must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.

!If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle.
It is better to have the vehicle transported than
to have it towed away.
If the vehicle has suffered transmission damage,
have it transported on a transporter or trailer.
The automatic transmission must be in position
N when the vehicle is being towed.
The battery must be connected and charged.
Otherwise, you:
Rcannot turn the SmartKey to position 2in the
ignition lock.
Rcannot shift the automatic transmission to
position N.
In the event of damage to the electrical sys-
tem
If the battery is defective, the automatic trans-
mission will be locked in position P. To shift the
automatic transmission to position N, you must
provide power to the vehicle's electrical system
in the same way as when jump-starting
(
Ypage 285).
Have the vehicle transported on a transporter or
trailer.
Disarm the automatic locking feature before the vehicle is towed (
Ypage 82). You could other-
wise be locked out when pushing or towing the
vehicle.

In the event ofdama ge to the electrical sys-
tem
If the battery isdefective, the automat ictrans-
mission will belocked inposition P. To shift the
automat ictransmission to position N, you must
pro vide power to the veh icle's electrical system
in the same way as when jump-starting
(

Fuses
Important safety notes
GWAR NING
If you man ipulate orbridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electr iccables could beoverloaded.
This could result ina fire. There isa risk of an
acc iden t and injury.
Alwa ys replace faulty fuses with the specified
new fuses having the correct amperage.
Blo wn fuses must bereplaced with fuses of the
same rating, which you can recognize bythe
color and value. The fuse ratings are listed inthe
fuse allocation chart.
The fuse allocation chart is located in the vehicle
tool kit in the stowage compartment under the
trunk floor (
Ypage 277).
If a ne wlyinserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
!Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Otherwise, components or systems could be
damaged.
!Make sure that no moisture can enter the
fuse box when the cover isopen.
!When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing inor dirt could otherwise impair the oper-
ation of the fuses.
The fuses in your vehicle serve to closedown
faulty circuits. Ifa fuse blows, all the compo-
nents on the circuit and their functions stop
operating.
Before changing a fuse
