Practical hints

Batteries

!

The factory-equipped VRLA battery is

leak-proofed. Only use a battery as replacement
that has the same security features and is of
identical size, voltage, and capacity as the
factory-equipped battery.

The battery, the battery ventilation and the
lateral plug must always be securely installed
when the vehicle is in operation.

Warning!

G

Failure to follow these instructions can

result in severe injury or death.

Never lean over batteries while connecting,

you might get injured.

Battery fluid contains sulfuric acid. Do not

allow this fluid to come in contact with eyes,

skin or clothing. In case it does, immediately

flush affected area with water and seek

medical help if necessary.

A battery will also produce hydrogen gas,

which is flammable and explosive. Keep

flames or sparks away from battery, avoid

improper connection of jumper cables,

smoking, etc.

!

Never loosen or detach battery terminal

clamps while the engine is running or the
SmartKey is in the starter switch. Otherwise the
alternator and other electronic components
could be severely damaged.

Have the starter battery checked regularly by an
authorized Mercedes-Benz Center.

Refer to Maintenance Booklet for maintenance
intervals or contact an authorized
Mercedes-Benz Center for further information.

Warning!

G

Do not place metal objects on the battery as

this could result in a short circuit.

Use leak-proof batteries only to avoid the

risk of acid burns in the event of an acci-

dent.

Warning!

G

The brake system requires electrical power

to operate.

A malfunction in the vehicle’s power supply

or electrical system may impair brake sys-

tem operation and switch it into its emer-

gency operation mode. The same applies if

battery is disconnected. To brake, the driver

must then apply significantly greater brake

pedal pressure and depress the pedal much

further to obtain the expected braking ef-

fect. If necessary, apply full pressure to the

brake pedal. Brakes are only applied to the

front wheels.

Stopping distance is increased! Adjust your

driving style accordingly. For more informa-

tion, see “Electro-hydraulic brake system”

(

page 94).
