60 Safety and SecurityOccupant safety

Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least 10 in
(25 cm) or more. You should be able to
accomplish this by a combination of ad-
justments to the seat and steering
wheel. If you have any problems, please
see an authorized Mercedes-Benz Cen-
ter.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.


Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.


Occupants, especially children, should
never lean their heads in the area of the
door where the side airbag inflates.
This could result in serious injuries or
death should the airbag be triggered. Al-
ways sit nearly upright, properly use the
seat belts and appropriate size infant or
child restraint system.


Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front airbag when it
is properly installed. Otherwise they will
be struck by the airbag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is extremely impor-
tant that you make the buyer aware of this
safety information. Be sure to give the buyer
this Operator's Manual.
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag.
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag which needs to deploy rapidly in a
side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side airbag inflates. This could result in


282 OperationTires and wheels
Tires and wheelsSee an authorized Mercedes-Benz Center
for information on tested and recommend-
ed rims and tires for summer and winter
operation. They can also offer advice con-
cerning tire service and purchase.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on
retreads. Mercedes-Benz can therefore
not assure the operating safety of the vehi-
cle when such tires are used.
See an authorized Mercedes-Benz Center
for information on tested and recommend-
ed rims and tires for summer and winter
operation.
Important guidelines

Only use sets of tires and rims of the
same type and make.


Tires must be of the correct size for the
rim.


Break in new tires for approximately
60 miles (100 km) at moderate
speeds.


Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire pressure loss and damage to
the tire beads.


If vehicle is heavily loaded, check tire
pressure and correct as required.


Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).


When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!
G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. See an authorized
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:

The wheel brakes or suspension compo-
nents can be damaged.


The correct operating clearance of the
wheels and the tires are no longer guar-
anteed.
Warning!
G
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can re-
sult in the bolts loosening and possibly an
accident.

291 Operation
Tires and wheels
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3 000
to 6 000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure. If nec-
essary, activate the tire inflation pressure
monitor.For information on wheel change, see the
“Practical hints” section (
page 344) and
(
page 361).
Warning!
G
Rotate front and rear wheels only if they are
of the same size.
!Your vehicle is equipped with a tire in-
flation pressure monitor, there are
electronic components built into the
wheel.
Do not use mounting tools in the area
of the valve as they could damage the
electronic components.
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 lb-ft (150 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

293 Operation
Winter driving
Block heater (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at an
authorized Mercedes-Benz Center.Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:


Use of snow chains is not permissible
with all wheel/tire combinations.


Snow chains should only be used on
the rear wheels. Follow the manufac-
turer's mounting instructions.


Only use snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.


Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
iWhen using snow chains, vehicles with
AIRMATIC should only be driven at
raised vehicle level (
page 219). Vehi-
cles with ABC* should only be driven at
vehicle height 1 (
page 221).
iWhen driving with snow chains, you
may wish to deactivate the
ESP (
page 80) before setting the ve-
hicle in motion. This will improve the
vehicle‘s traction.
!Even on vehicles with all-wheel drive,
use snow chains on rear tires only.
Do not use snow chains with tire sizes
245/45 R 18 on 8
1/2 x 18 rims and
265/40 R 18 in general (
page 384).
Do not use snow chains on tires mount-
ed on AMG rims.

(except Sport Package*)
The spare wheel rim is mounted with a full
sized tire of the same type as on the vehi-
cle, and it is fully functional.
However, that spare wheel rim is weight
optimized and has a limited service life of
12 000 miles (20 000 km) use before a
standard wheel rim must replace it.
In case of flat tire, you may temporarily use
the spare wheel.
Do not operate vehicle with more than one
spare wheel mounted.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.
