more than one to two revolutions. Other-
wise, hydraulic fluid could escape. X
Set jack :on solid ground.
X Position jack :on the axle carrier tube ;
of the front or rear axle. Jack :must
always stand vertically, even on slopes.
Make sure that jack :is correctly posi-
tioned under axle carrier tube ;. The front
or rear axle must sit securely in the recess of jack :.
X Raise the vehicle by pumping in the direc-
tion of the arrow until the tire is 1.2 in
(3 cm) off the ground at the most.
Removing a wheel !
Do not place wheel bolts in sand or on a
dirty surface. The bolt and wheel hub
threads could otherwise be damaged when you screw them in.
X Unscrew the wheel bolts.
X Remove the wheel.
Mounting a new wheel G
WARNING
Oiled or greased wheel bolts/wheel nuts and damaged wheel bolt/wheel nut/wheel hub
threads can cause wheel bolts/wheel nuts to come loose. As a result, you could lose a wheel while driving. There is a risk of an acci-
dent.
Never oil or grease wheel bolts/wheel nuts. In the event of damage to the threads, contact a
qualified specialist workshop immediately.
Have the damaged wheel bolts/wheel nuts or hub threads replaced/renewed. Do not con-
tinue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" sec-
tion (Y page 327).
X Clean the wheel and wheel hub contact
surfaces.
X Place the new wheel on the wheel hub and
push it on.
X Tighten the wheel bolts until they are fin-
ger-tight.
Lowering the vehicle G
WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed. 330
Changing a wheelWheels and tires

X
Open the pressure release screw on the
jack using the pump lever (Y page 328) by
approximately one turn.
X Lower the vehicle until it is once again
standing firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated ( :
to A). The specified tightening torque is
96 lb-ft (130 Nm).
X Disassemble the pump lever.
X Push the jack piston back in and close the
drain plug.
X Use the bolts to secure the faulty wheel to
the spare wheel bracket (Y page 291).
X Stow the jack and the vehicle tools in the
vehicle again.
X Check the tire pressure of the newly instal-
led wheel and adjust it if necessary.
A table with the tire pressures for your vehi-cle can be found on the B-pillar on the driv-
er's side. Wheel and tire combinations
General notes
G
WARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent. Always replace wheels and tires with those
that fulfill the specifications of the original
part.
When replacing wheels, make sure to use the
correct:
R designation
R model
When replacing tires, make sure to use the
correct:
R designation
R manufacturer
R model G
Warning
A flat tire severely impairs the driving, steer-
ing 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.
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tires, wheels
and accessories which have been approved by Mercedes-Benz specifically for your
vehicle. These tires have been specially
adapted for use with the driving safety sys-
tems, such as ABS or ESP ®
.
Only use tires, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tire dimen-
sion variations could cause the tires to
come into contact with the bodywork and
axle components. This could result in dam-
age to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those tes- ted and approved.
Further information about wheels, tires and
approved combinations can be obtained Wheel and tire combinations

from any authorized Mercedes-Benz Cen-
ter.
i The recommended pressures for various
operating conditions can be found:
R on the Tire and Loading Information plac-
ard with the recommended tire pres-
sures on the B-pillar on the driver's side
R in the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire
pressure under various operating condi-
tions.
Check tire pressures regularly, and only
when the tires are cold. Comply with the
maintenance recommendations of the tire
manufacturer in the vehicle document wal- let.
Further information on recommended tire
pressures as well as tire pressures for spe-
cific driving situations, see (Y page 325).
i Notes on the vehicle equipment – always
equip the vehicle with:
R tires of the same size on a given axle
(left/right)
R tires of the same type on your vehicle at
a given time (summer tires, winter tires,
all-weather tires, all-terrain tires)
i The following pages contain information
on approved wheels and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory as standard equipment or optional extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size. The size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the equip-
ment installed at the factory.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.
i Not all wheel and tire combinations are
available at the factory for all countries. 332

GVWR is the maximum permissible gross
weight of the vehicle. Gross vehicle weight (GVW) is the vehicle weight including fuel,
service products, spare wheel, accessoriesinstalled, load and, if applicable, trailer
drawbar load. The GVW must never exceed
the GVWR.
i The GAWR is the maximum permissible
axle weight. Vehicle data for off-road driving
Fording depth
! The depth of water must not exceed the
value specified in the table. Note that the
possible fording depth is less in flowing
water. The table shows fording depth

ded and ready to drive. Fording depth 24 in (60 cm)

Approach/departure angle
G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. For vehicles with steel springs, loaded and
ready to drive means: a full tank, all fluids
refilled and the driver is in the vehicle.

For further information about approach/
departure angles, see (Y
page 161).Maximum gradient-climbing capabil-
ity
Note that the vehicle's gradient-climbing
capability depends on the off-road conditions and the road surface conditions.
On good road surfaces the maximum gradi-
ent-climbing capability of your vehicle is
100%, which corresponds to an approach/
departure angle of 45°.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep ter-
rain. i
If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS detects this and brakes the wheels
accordingly. The rear wheel torque is
increased, making it easier to drive off.
For further information about the maximum
gradient climbing ability, see (Y page 161). Trailer tow hitch
Mounting dimensions
Only have a trailer tow hitch retrofitted at a
qualified specialist workshop.
! If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may
be necessary, depending on the vehicle
type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chas- sis frame. :
