2016 MERCEDES-BENZ CLS Owners Manual

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: R
The 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. R
You may only jump-start the vehicle when the engine and exhaust system are cold. R
Only jump-start from batteries with a 12 V voltage rating. R
Only use jumper cables which have a sufficient 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
a few 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 a s the V-belt pulley or the fan.X

Fuses
Important safety notes
G WAR NING
If you manipulate or brid ge a faulty fuse or if
you replace it wit h a fuse wit h a higher amper-
age, the electr ic cables could be overloaded.
This could result in a fire. There is a risk of an
acc iden t and injury. Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blo wn fuses must be replaced with fuses of the
same rating, whic h you can recognize by the
color and value. The fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is located in the vehicle
tool kit in the stowage compartment under the
trunk floor ( Y
page 286).
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
! On ly use fuses that have been appr oved for
Mercedes-Benz vehicles and whic h 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 is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses.
The fuses in your vehicle ser ve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions stop
operating.

heavily laden and adjust prio r to a trip.
While driving , pay attention to vibrations, noises
and unusual handlin g characteristics , e.g. pull-
ing to on e side . This may indicat e that th e
wheels or tires are damaged. If you suspec t that
a tire is defective, reduce your spee d immedi-
ately. Stop th e vehicl e as soo n as possible to
chec k th e wheels and tires for damage. Hidden
tire damag e could also be causing th e unusual
handlin g characteristics . If you fin d no sign s of
damage, hav e th e tires and wheels checke d at a
qualified specialist workshop.
When parking your vehicle, mak e sur e that th e
tires do no t get deformed by th e cur b or other
obstacles. If they canno t be avoided, driv e ove r
obstacles suc h as curbs slowly and at an obtuse
angle. Otherwise, you may damag e th e wheels
or tires .
Regular checking of wheels and tires
G WARNIN G
Damaged tires can caus e tire inflation pres-
sur e loss . As a result , you could lose control of
your vehicle. Ther e is a ris k of accident.
Chec k th e tires regularly for sign s of damag e
and replace any damaged tires immediately. Operation 301
Wheels and tires Z

Check wheels and tires for damage at least once
a month. Check wheels and tires after driv ing
off-road or on rough roads. Damaged wheels
can cause a loss of tire pressure. Pay particular
attention to damage such as: R
cuts in the tiresR
punctures R
tears in the tiresR
bulges on tires R
deformation or severe corrosion on wheels
Regular ly check the tire tread dept h and the
condition of the tread across the whole widt h of
the tire ( Y
page 302). If necessary, turn the
front wheels to full lock in order to inspect the
inner side of the tire surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not mount
anything onto the valve other than the standard
valve cap or other valve caps approved by
Mercedes-Benz for your veh icle . Do not use any
other valve caps or systems, e.g. tire pressure
monitoring systems.
Regular ly check the pressure of all the tires par-
ticularly prio r to long tr ips. Adjust the tire pres-
sure as necessary ( Y
page 304).
Observe the notes on the emergency spare
wheel ( Y
page 326).
The service life of tires depends, among other
things, on the foll owin g factors:R
driv ing styleR
tire pressure R
dist ance covered
Notes on tire tread
G WAR NING
In suff icie nt tire tread will reduce tire traction.
The tire is no longer able to dissipat e water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driv ing con-
dit ions. There is a risk of acc iden t.
If the tire pressure is too high or too low, tires
may ex hibit diff erent leve ls of wear at diff er-
ent locations on the tire tread. Thus, you
should regularly check the tread dept h and
the condition of the tread across the entire
widt h of all tires. Minimum tire tread depth for: R
