2013 MERCEDES-BENZ R-CLASS FAMILY TOURER seats

Traction
Traction is the result of friction between the
tires and the road surface.
TWR (Tongue Weight Rating)
The TWR specifies the maximu
mpermissible
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 áin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions.
Total load limit
Rated cargo and luggage load plus
68 kilograms (150 lb) multiplied by the
number of seats in the vehicle. Changing
awheel Flat tire
The "Breakdown assistance" section
(Y page 299) contains information and notes
on how to deal with a fla ttire. Instructions for
driving with MOExtended tires in the eventof
a flat tire are also provided there.
Vehicle with emergency spare wheel: in
the event of a flat tire, the emergency spare
wheel is mounted as described under
"Mounting a wheel" ( Ypage 335). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impai rthe 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
accident. 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
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed at a qualified
specialist workshop.
Always observe the instructions and safety
notes in the "Mounting awheel" section
(Y page 335).
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
intervals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
available, the tires should then be replaced
every 3000 to 6000 miles (5000 to
10,000 km), or earlier if the tire wear requires
this. Do not change the direction of wheel
rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tire pressure and,
if necessary, restart the tire pressure loss
warning system or the tire pressure monitor. Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tire indicates
its correct direction of rotation. 334
