Towing and tow-starting
Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer available if:
Rthe engine is not running.
Rthe brake system or the power steering is
malfunctioning.
Rthere is a malfunction in the voltage supply or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible
gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
!If DISTRONIC PLUS or the HOLD function is
activated, the vehicle brakes automatically in
certain situations. To prevent damage to the
vehicle, deactivate DISTRONIC PLUS and the
HOLD function in the following or other simi-
lar situations:
Rwhen towing the vehicle
Rin the car wash
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of 30 mph
(50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
!Only secure the tow cable or tow bar to the
towing eyes. You could otherwise damage the
vehicle.
!Do not tow with sling-type equipment. This
could damage the vehicle.
!Do not use the towing eyes for recovery pur-
poses as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
!When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
!Your vehicles is equipped with an automatic
transmission. Therefore, you must not have
the vehicle tow-started. The transmission
may otherwise be damaged.
iDetails on the permissible gross vehicle
weight of your vehicle can be found on the
vehicle identification plate (
Ypage 288).
256Towing and tow-starting
Breakdown assistance
It is better to have the vehicle transported than
to have it towed away.
If the transfer case can be shifted into neutralN,
you can tow the vehicle.
If the transfer case cannot be shifted into neu-
tral N, you can tow the vehicle with one axle
raised. Please bear the following in mind:
Rremove the propeller shaft between the trans-
fer case and the rolling axle.
Rturn the SmartKey to position 1in the ignition
lock (Ypage 112).
The battery must be connected and charged.
Otherwise, you:
Rcannot turn the SmartKey to position 2in the
ignition lock (Ypage 112).
Rcannot shift the automatic transmission to
position N.
iDisarm the automatic locking feature before
the vehicle is towed (Ypage 66). You could
otherwise be locked out when pushing or tow-
ing the vehicle.
Towing eyes
Towing eyes, front
:Towing eyes, front
Towing eye, rear
Rear towing eye :is located under the bumper,
on the left-hand side when viewed in the direc-
tion of travel.
Towing a vehicle with both axles on
the ground
It is important that you observe the safety
instructions when towing away your vehicle
(
Ypage 256).
XSwitch on the hazard warning lamps
(Ypage 89).
iIn order to signal a change of direction when
towing the vehicle with the hazard warning
lamps switched on, use the combination
switch as usual. In this case, only the indicator
lamps for the direction of travel flash. After
resetting the combination switch, the hazard
warning lamp starts flashing again.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 112).
XWhen the vehicle is stationary, depress the
brake pedal and keep it depressed.
XShift the transfer case to neutral position
N (Ypage 163).
XShift the automatic transmission to position
N.
XRelease the brake pedal.
XRelease the parking brake (Ypage 131).
iThe transmission can only change gear if the
battery has sufficient charge.
If you cannot move the selector lever to N, the
propeller shafts to the driven axles must be
removed.

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-per-
formance 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 pur-
chasers. The TIN is made up of the manufactur- er'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 capa-
city 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 distrib-
uted 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
Flat tire
The "Breakdown assistance" section
(Ypage 250) contains information and notes on
how to deal with a flat tire.
Rotating the wheels
GWARNING
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 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 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"
(
Ypage 282).
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 no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 miles (5,000 to 10,000 km), or earlier if
tire wear requires. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rota-
