2015 MERCEDES-BENZ G-Class roof

Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

General notes i
When they leave the factory, vehicles are
not equipped with the tools needed to
change a wheel, such as a jack or lug
wrench. Some tools for changing a wheel
are specific to the vehicle. To obtain tools
approved for your vehicle, contact a quali-
fied specialist workshop.
The vehicle tool kit contains: R vehicle tool kit bag with:
- fuse extractor
- an Allen key, e.g. to operate the sliding
roof manually in an emergency
- a pump lever for the vehicle jack
- a screwdriver
- Lug wrench
R jack

footwell in front of the rear bench seat.

Jack !
Make sure that, while installing the vehi-
cle jack, there are no cables on the holder, in order to avoid them becoming trapped. 290

Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only mount approved tires of the correct
size onto the wheels.
R Tires are supplied with a protective layer
from the factory. Break in new tires at mod-
erate speeds for the first 60 miles
(100 km). They only reach their full per-
formance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear. This also applies to the spare wheel. Winter operation
General notes
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 327). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and braking power. Change the tires on your vehi-cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident. M+S tires with a tread depth of less than
ãin
(4 mm) must be replaced immediately. G
WARNING
Wheel and tire dimensions as well as the type of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may be severely affected. There is a risk of an acci-
dent.
In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from the
wheel to be replaced for a short time.
R do not deactivate ESP ®
.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
Do not exceed a maximum speed of 50 mph
(80 km/h) if a spare wheel of a different size is installed.
At temperatures below 45 ‡ (+7 †), use all-
season tires or winter tires. Both types of tire
are identified by the M+S marking.
Not all tires with the M+S marking provide the
driving characteristics of winter tires. In addi-
tion to the M+S marking, winter tires also
have the isnowflake symbol on the tire
wall. Tires with this marking fulfill the require-
ments of the Rubber Manufacturers Associa-
tion (RMA) and the Rubber Association of
Canada (RAC) regarding snow traction, and
were specially developed for driving on snow.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter, since these tires have been
designed specifically for driving on snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac-
teristics. 308

brakes, level control, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the accesso-
ries.
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 dis-
tributed over the tire tread. If the tire tread is
level with the bars, the wear limit of áin
(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 lb
(68 kilograms) multiplied by the number of
seats in the vehicle. Changing a wheel

The "Breakdown assistance" section
(Y page 292) contains information and notes
on how to deal with a flat tire. Rotating the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec- tronic components.
Only have tires changed at a qualified spe-cialist workshop.
Rotating front and rear wheels of differing
dimensions can render the general operating permit invalid.
Always pay attention to the instructions and
safety notices in the section on "Changing a
wheel and mounting a spare wheel"
(Y page 328).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
If your vehicle's tire configuration allows, you can rotate the wheels according to the inter-
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, the tires should be rotated Changing a wheel
