ted. Check the tire pressure and reactivate the
tire pressure monitor (Ypage 268)if necessary.
Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of hydro-
planing. 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.
You may mount the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in a cool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
GWARNING
When you remove the spare wheel from the
spare wheel bracket, the vehicle’s weight dis-
tribution changes. If the vehicle is already
raised, the jack could tip over. There is a risk
of injury.
Remove the spare wheel from the spare wheel
bracket before lifting the vehicle.
XPrepare the vehicle as described
(Ypage 250).
XRemove the vehicle tool kit and the jack
(Ypage 248).
XSecure the vehicle to prevent it from rolling
away.
XRemove the spare wheel from the spare wheel
bracket (Ypage 249).
iVehicles without a spare wheel or emer-
gency spare wheel are not equipped with a
tire-change tool kit at the factory. For more
information on which tools are required to
perform a wheel change on your vehicle e.g. lug wrench or jack, consult an authorized
Mercedes-Benz Center.
Securing the vehicle to prevent it from
rolling away
XOn level ground:
place chocks or other suit-
able items under the front and rear of the
wheel that is diagonally opposite the wheel
you wish to change.
XOn downhill gradients: place chocks or
other suitable items in front of the wheels of
the front and rear axle.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
!The jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
Observe the following when raising the vehicle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not suited for performing main-
tenance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not

Mounting a new wheel
GWARNING
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.
GWARNING
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" section
(
Ypage 281).
XClean the wheel and wheel hub contact sur-
faces.
XPlace the new wheel on the wheel hub and
push it on.
XTighten the wheel bolts until they are finger-
tight.
Lowering the vehicle
GWARNING
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.
XOpen the pressure release screw on the jack
using the pump lever (Ypage 282) by approx-
imately one turn.
XLower the vehicle until it is once again stand-
ing firmly on the ground.
XPlace the jack to one side.
XTighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: toA).
The specified tightening torque is 96 lb-ft
(130 Nm).
XDisassemble the pump lever.
XPush the jack piston back in and close the
drain plug.
XUse the bolts to secure the faulty wheel to the
spare wheel bracket (Ypage 249).
XStow the jack and the vehicle tools in the
vehicle again.
XCheck the tire pressure of the newly installed
wheel and adjust it if necessary.
A table with the tire pressures for your vehicle can be found on the B-pillar on the driver's
side.
Wheel and tire combinations
General notes
GWARNING
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.

Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is fil-
led with refrigerant R‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged.
Service work, such as topping up refrigerant or
replacing components, may only be carried out
by a qualified specialist workshop. All applicable
regulations must be adhered to, SAE standard
J639 included.
Always have work on the climate control system
carried out at a qualified specialist workshop.

Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(
Ypage 289).
The brake fluid change intervals can be found in
the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB Approval
331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.

Maximum gradient-climbing capabil-
ity
Note that the vehicle's gradient-climbing capa-
bility depends on the off-road conditions and theroad surface conditions.
On good road surfaces the maximum gradient-
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.
iIf 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 eas-
ier to drive off.
For further information about the maximum gra-
dient climbing ability, see (
Ypage 140).
