Battery (vehicle)
12 V battery – important safety notes
Special tools and expert knowledge are requiredwhen working on the battery, e.g. removal andinstallation. You should therefore have all workinvolving the battery carried out at a qualifiedspecialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car-
ried out at a qualified specialist workshop.
For further information about ABS and ESP®,see (Ypage 65) and (Ypage 68).
All vehicles except vehicles with a lithium-ion battery:
GWARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms whencharging the battery as well as when jump-start-ing.
Always make sure that neither you nor the bat-tery is electrostatically charged. A build-up ofelectrostatic charge can be caused, for exam-ple:
Rby wearing clothing made from syntheticfibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the car-pet or other synthetic materials
Rif you rub the battery with a cloth
GWARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.

In order for the battery to achieve the maximumpossible service life, it must always be suffi-ciently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehicle.In this case, have the battery disconnected at aqualified specialist workshop. You can alsocharge the battery with a charger recommendedby Mercedes-Benz. Contact a qualified special-ist workshop for further information.
Have the battery charge state checked morefrequently if you use the vehicle mainly for shorttrips or if you leave it standing idle for a lengthyperiod. Consult a qualified specialist workshopif you wish to leave your vehicle parked for a longperiod of time.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy, thusconserving battery power.
Charging the 12 V battery
Vehicles with a lithium-ion battery:
!Only use battery chargers with a maximumcharging voltage of 14.4 V.
All vehicles except vehicles with a lithium-ion battery:
!Only use battery chargers with a maximumcharging voltage of 14.8 V.
GWARNING

Tire and Loading Information placard
CRecommended tire pressures
The Tire and Loading Information placard is onthe B-pillar on the driver's side (Ypage 340).
The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires. The recommended tire pressures are validfor the maximum permissible load and up to themaximum permissible vehicle speed.
Tire pressure table
The tire pressure table is on the inside of the fuelfiller flap. It shows the tire pressure for all tirespermitted at the factory for this vehicle; seeillustration (example).
The tire pressure table contains the recommen-ded pressures for cold tires for various operat-ing conditions, i.e. differing load and speed con-ditions.
If a tire size precedes a tire pressure, the tirepressure information following is only valid forthat tire size. If a speed range precedes the tirepressure, the following tire pressure dataapplies to only this speed range.
The load conditions "partially laden" and "fullyladen" are defined in the table for different num-
bers of occupants and amounts of luggage. Theactual number of seats may differ.
Some tire pressure tables show only the rimdiameters instead of the full tire size, e.g.R18.Rim diameter is part of the tire size and can befound on the tire sidewall (Ypage 345).
If the tire pressures have been set to the lowervalues for lighter loads and/or lower roadspeeds, the pressures should be reset to thehigher values:
Rif you want to drive with an increased loadand/or
Rif you want to drive at higher road speeds
The tire pressures for increased loads and/orhigher road speeds, shown in the tire pressuretable, may have a negative effect on drivingcomfort.
If the tire pressure is not set correctly, this canlead to an excessive build up of heat and a sud-den loss of pressure.
For more information, contact a qualified spe-cialist workshop.
Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
RCheck the tire for foreign objects.
RCheck whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
