Risk of accident Your vehicle's handling characteristics will
change when a "Minispare" emergency
spare wheel is fitted. Adapt your style of
driving accordingly. The same applies where
a spare wheel is
mounted on the rear axle.
You may only use the "Minispare" emergen-
cy spare wheel or the spare wheel for a short
period on the rear axle, and may drive at a
maximum speed of 80 km /h. Have the
"Minispare" emergency spare
wheel or the spare wheel on the rear axle re-
placed with a new wheel at the nearest qual-
ified specialist workshop, e.g. a Mercedes-
Benz Service Centre.
Never drive the vehicle with more than one
"Minispare" emergency spare wheel fitted. P 40.10-2599-31209en_d2.boo Seite

Make sure that th estanding surface for the
jack is firm, eve nand not slippery. Do not
us eblocks of wood or similar as jacking sup-
po rts, as the jack will not be able to ac hieve
it s load-bearing capacity due to the restrict-
ed height.
Do not start the engine at any time wh ilet he
wheel is being changed.
Do not crawl under the vehicle while itis
supported by the jack. If you do not raise the
vehicle in the way described, it could slip off
the jack (e.g. when the engineis star ted or
the doors orboot lid areop ened or closed). P 40.10-2600-31

You can only use the MOE emergency run-
flat system in conjunction with the tyre
pressure loss warning.
! The maximum distance you may cover in
run-flat mode depends on the vehicle load. It is
50 km if the vehicle is partially laden and 30 km
if it is fully laden.
The maximum distance that may be drive nin run-
flat mode begins from the time the tyre pressure
loss warning appears in the multi-function dis-
play.
Yo u must not exceed a maximum speed of
80 km /h. P 40.10-2740-31 G
Risk of accident The wheel bolts may work loose if they are
not tightene dto a tightening torque of
11 0Nm . For this reason, you should have
the tightening torque checked as soonas
possible after a wheel change. MOE

374 Practical advice
Flat tyrei
The maxim umdistance can beincreased
co nsiderably by using TIREFIT before starting
ru n-flat mode. Ifthe type of damag eis suc h that
TIREFIT cannot seal the tyre, you can still drive
the maxim um possible distance in run-flat mode. i
Ifyo u are replacing oneor more tyres, make
sure you usetyres with the "MOExtended” mark
and which are the specified size for the vehicle.
If you are replac ing one ormo re rims, make
sure you use rims approved for use with
"MOExtended” tyres and which are the specified
size for the vehicle. G
Risk of accident The handling characteristics of your vehicle
ar e adversely affected in run-flat mode, for
example:
! when cornering
! when braking
! when accelerating suddenly
You should therefor eadapt your driving
style accordingly and avoid making sudden
st eering movem ents, accelerating suddenly
and driving over obstacles (kerbs, pot holes,
off-road). The applies especially ifthe vehi-
cle is heavily laden.
The distance that can be tra velled in run-flat
mode depends la rgely on the loads placed
on the vehicle. Speed, load, sudd enacceler-
ation, road-surf aceco nditions, outside tem-
peratures, etc. can considerably reduce this
distance, whereas a conservative dr iving
st yle may inc reaseit. Run-fla
tmodemust bestopped in the event
of:
! bangi ng noises
! the vehicle shaking
! smoke development accomp anied by
the smell of rubber
! ESP continuously intervening
! tears in the tyre sid ewalls
After driving in run-flat mode, you must have
the rim checked to see if it can still be use d.
For this purpose, visit a qua lified specialist
workshop which has th e necessary special-
ist knowledge and tools to carry out the
work required. The flat tyre must be re-
placed inany case.
Mercedes -Benz recommends that you use a
Mercedes -Benz Service Centre for this pur-
pose. Inparticular, work relevant to safety
or on safety-relate dsystems must be car-
ried out at a qualified specialist workshop. 209en_d2.boo Seite

Practical advice
Battery
Your vehicle is equipped with a battery.
The battery must always be sufficiently
charged so that it achieves its intended
service life.
Have the battery charge checked more
frequently if you use the vehicle mainly for
short trips or ifyou do not use it for an ex-
tended period.
To prevent corrosion damage, only replace
the battery with a ba ttery that has acentral
ve ntilation cover. For safety reasons,
Mercedes-Benz recommends that you only
use batteries which have been specially
tested and approved for your vehicle by
Mercedes-Benz.
Consult a Mercedes-Benz Service Centre if
you wish toleave your vehiclepark edup
for an extended period. Batt

!Switch offthe engine and remove thekey
before you loose nor disconnect the terminal
clamps from the batter y.You may otherwise de-
st roy electronic components, e.g. the alternator.
Have the starter batter yche cked and, ifneces-
sary, replaced every two years or at least every
20,000 km ata qualified specialist workshop,
e.g. a Merce des-Be nz Service Centre. The battery
islocated in the engine com-
partment on the right-hand side, when

Risk of inju ry For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which
have bee
nsp ecially tested and approved for
your vehicl eby Mercedes-Benz. These bat-
teries are more impact-re sistant so that oc-
cup ants do not suffer acid burns if a battery
is damaged in the event of an accident.
To prevent acid burn sand scald ing, you
must obse rve the following safety precau-
tions wh enhandling batteries:
! Do not lean over the battery.
! Do not place any metal objects on the
battery. You could otherwise cause a
short circuit and the highly explosive gas
mixture in the battery could ignite.
! Make sure that you do not become elec-
trostatically charged, e.g. by wearing
synthetic clothing or due to friction be-
tween fabric s.Do not therefore pull or
pu sh the battery over carpete dfloors or
other synthetic materials. !
Do not touch the battery under any ci r-
cums tances. To eliminate any electro-
static charge, first get out of the vehicle
and touch the bodywork.
! Do not rub the batt ery with a cloth. The
battery could explode due to electro-
static charging when you touch the bat-
tery or even by sparks ar cing between
you and the battery.
