In addition to the vehicle load, the driving
distance possible depends upon:
RSpeed
RRoadcondition
ROutside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
throughamoderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You must not exceedamaximum speed of
50 mph (80 km/h).
iWhen replacing one or all tires, make sure
that you use only tires:
Rof the size specified for the vehicle and

batteries. Wash battery acid immediately with
water and seek medical attention.
GWARNING
Adischarged battery can freeze at
temperatures below freezingpoint.When
jump-starting the vehicle or charging the
battery, gases can escape from the battery.
There isarisk 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-
startingconnection point.
The jump-starting connection point is in the
engine compartment(Ypage 326).
XOpen the hood (Ypage 306).
XConnect 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
(Ypage 326).
If, at low temperatures, the indicator lamps/
warning lamps in the instrumentcluster do
not light up, it is highly likely that the
discharged battery has frozen.Inthis case,
you may neither charge the battery nor jump-
start the vehicle. The service life ofathawed-
out battery may be shorter. The starting
characteristics may be impaired, especiallyat
low temperatures. Have the thawed-out
battery checked ataqualified specialist
workshop.
Never chargeabattery still installed in the
vehicle unlessabattery charger unit
approved by Mercedes-Benzisbeing used. A
battery charger unit speciallyadapted 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.

Example: tire pressure table with tire dimensions
Ifatire size precedesatire pressure, the tire
pressure informationfollowing is only valid
for that tire size. The load conditions "partially
laden" and "fully laden" are defined in the
table for different numbers of occupantsand
amounts of luggage. The actual number of
seats may differ.
Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18.The rim diameter is part of the tire size
and can be found on the tire sidewall
(Ypage 351).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset
to the higher values:
Rif you want to drive with an increased load
and/or
Rif you want to drive at higher road speeds.
iThe tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may haveanegative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build up of heat and
asudden loss of pressure.
For more information, contactaqualified
specialist 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 inatire
blow-out. There isarisk 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,
contactaqualified specialist workshop.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss. There
isarisk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Useasuitable pressure gauge to check the
tire pressure. The outer appearance ofatire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitoring
system, the tire pressure can be checked
using the on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion.This is
dependent on the driving speed and the load.
Therefore, you should only correct tire
pressures when the tires are cold.
