2013 MERCEDES-BENZ G-Class rims

Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
G
WARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
R No modifications of any kind may be made
to any components or wiring of the SRS.
R Do not change or remove any component
or part of the SRS.
R Do not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, front-passenger front air bag
cover, outer sides of the seat backrests,
door trim panels, or door frame trims.
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.). R
Do not hang items such as coat hangers
from the coat hooks or handles over the
door.

These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
R Air bag system components will be hot after
an air bag has inflated. Do not touch them.
R Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R Improper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
R For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicable section in the Operator's Manual. 40

If

you cannot move the selector lever to N,
the propeller shafts to the driven axles
must be removed. Transporting the vehicle
! Only

lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components.
Otherwise, the vehicle could be damaged. Use the towing eyes to pull the vehicle if it
needs to be transported on a trailer or
transporter (
Y page 311).
X Apply the parking brake.
X Turn the SmartKey to position 2 in the
ignition lock ( Y page 139).
X Move the selector lever to N.
X Shift the transfer case to
neutral (Y page 200).
X Secure the towing cable to the towing eyes
(Y page 311).
X Make sure that the vehicle cannot roll
away.
X Release the parking brake.
X Load the vehicle onto the transporter.
As soon as the vehicle is loaded:
X Apply the parking brake.
X Shift the automatic transmission to
position P.
X Turn the SmartKey to position 0 in the
ignition lock ( Y page 139) and remove it.
X Secure the vehicle. Recovering a vehicle that has become
stuck
! Pull away smoothly, slowly, and in a
straight

line when pulling out a vehicle that
has become stuck. Excessive tractive
power could damage the vehicles.
If the drive wheels get trapped on loose or
muddy ground, recover the vehicle with the
utmost care, especially so if the vehicle is
laden.
Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible,
using the tracks it made when it became
stuck. 312

WARNING
Replace rims or tires with the same
designation,
manufacturer and type as shown
on the original part. For further information
contact an authorized Mercedes-Benz Center.
If incorrectly sized rims and tires are
mounted, the wheel brakes or suspension
components can be damaged. Also, the
operating clearance of the wheels and the
tires may no longer be correct. G
WARNING
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular

rim type. Failure to do so can result
in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or
recommended by Mercedes-Benz, since
previous damage cannot always be
recognized on retreads. The operating safety
of the vehicle cannot be assured when such
tires are used. G
WARNING
If you notice sudden significant vibrations or
unusual handling performance or if you
suspect that damage has occurred to the
vehicle, you should activate the hazard
warning lamps, gently reduce speed and
carefully head for an area that is located at a
safe distance from the road.
Check the tires and the underside of the
vehicle for damage. If the vehicle seems
unsafe, have the vehicle towed away to the
nearest Mercedes-Benz Center or tire dealer
to be repaired. G
WARNING
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
might lose control of the vehicle. Continued
driving

with a flat tire or driving at high speed
with a flat tire will cause excessive heat build-
up and possibly a fire. G
Warning
A flat tire severely impairs the driving,
steering and braking characteristics of the
vehicle. There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
Consult

an authorized Mercedes-Benz Center
if you require information on approved and
recommended tires and wheels for summer
and winter operation. Advice on purchasing
and caring for tires is also available there.
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist
workshop and ask about:
R suitability
R legal stipulations
R factory recommendations318
Important safety notes
Wheels and tires

Bead
The tire bead ensures that the tire sits
securely
on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg

(5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the
accessories.
TIN (Tire Identification Number) This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example

for a product recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index The load bearing index (also load index) is a
code

that contains the maximum load bearing
capacity of a tire.
Traction Traction is the result of friction between the
tires and the road surface.
TWR (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight

that the ball coupling of the trailer tow
hitch can support. Treadwear indicators Narrow bars (tread wear bars) that are
distributed

over the tire tread. If the tire tread
is level with the bars, the wear limit of á in
(1.6 mm) has been reached.
Occupant distribution The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Nominal load and luggage load plus 150 lbs
(68 kg) multiplied by the number of seats in
the vehicle.
