Roadside Assistance<br />
the moment the tire pressure loss warning<br />
appears in the multifunction display.<br />
You must not exceed a maximum speed of<br />
50 mph(80 km/h).<br />
G Warning!<br />
The handling characteristics of your vehicle<br />
deteriorate in run-flat mode, for example:<br />
Rwhen cornering<br />
Rwhen braking<br />
Rwhen accelerating rapidly<br />
Adapt your driving style accordingly and avoid<br />
sudden changes in direction and sudden<br />
acceleration, as well as driving over obstacles<br />
(i.e. curbs, potholes), and driving off-road.<br />
This is particularly the case when the vehicle<br />
is heavily laden.<br />
The maximum permissible distance that can<br />
be driven in run-flat mode depends to a large<br />
extent on the loads placed on the vehicle. It<br />
can be shorter due to high speeds, a heavy<br />
cargo, sudden changes in direction, the road<br />
surface condition, outside temperature, etc.,<br />
or further if you drive carefully and<br />
conservatively.<br />
Do not continue to drive in run-flat mode if:<br />
Ryou hear banging noises.<br />
Rthe vehicle starts to shake.<br />
Ryou see smoke and smell rubber.<br />
RESP ® is intervening constantly.<br />
Rthere are tears in the sidewalls of the tire.<br />
After driving in run-flat mode, you must have<br />
the wheel(s) checked for damage at a<br />
qualified specialist workshop which has the<br />
necessary specialist knowledge and tools to<br />
carry out the work required. The faulty tire<br />
must be replaced in every case.<br />
<strong>Mercedes</strong>-<strong>Benz</strong> recommends that you use an<br />
authorized <strong>Mercedes</strong>-<strong>Benz</strong> Center for this<br />
purpose. In particular, work relevant to safety<br />
or on safety-related systems must be carried<br />
out at a qualified specialist workshop.<br />
i When replacing one or all tires, make sure<br />
that you only use tires marked<br />
MOExtended and of the specified size for<br />
the vehicle.<br />
i Vehicles featuring the MOExtended runflat<br />
system are not equipped with TIREFIT<br />
kit at the factory. It is therefore<br />
recommended that you additionally equip<br />
your vehicle with the TIREFIT kit if you<br />
mount tires that do not feature run-flat<br />
properties, e.g. winter tires. You can obtain<br />
a TIREFIT kit from an authorized <strong>Mercedes</strong>-<br />
<strong>Benz</strong> Center, for example.<br />
Battery<br />
Important safety notes<br />
In order for the battery to achieve the<br />
maximum possible service life, it must always<br />
be sufficiently charged.<br />
! Have the battery checked regularly at a<br />
qualified specialist workshop, e.g. an<br />
authorized <strong>Mercedes</strong>-<strong>Benz</strong> Center.<br />
Observe the service intervals in the Service<br />
Booklet or for further information consult a<br />
qualified specialist workshop, e.g. an<br />
authorized <strong>Mercedes</strong>-<strong>Benz</strong> Center.<br />
Have the battery charge checked more<br />
frequently if you use the vehicle mainly for<br />
short trips or if you leave it standing idle for<br />
a lengthy period.<br />
To prevent damage from corrosion, only<br />
replace the battery with one that has a central<br />
ventilation cover.<br />
Only replace a battery with a battery that has<br />
been recommended by <strong>Mercedes</strong>-<strong>Benz</strong>.<br />
Consult an authorized <strong>Mercedes</strong>-<strong>Benz</strong> Center<br />
if you wish to leave your vehicle parked up for<br />
a long period of time.<br />
