Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type of the spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergency spare wheel that differs in size.
Ronly use a spare wheel or emergency spare
wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergency spare wheel or spare
wheel of a different size, you must not exceed
the maximum speed of 50 mph (80 km/h).
Snow chains must not be mounted on emer-
gency spare wheels.
General notes
Mounting the emergency spare wheel is descri- bed under "Mounting a wheel" (Ypage 409).
You should regularly check the pressure of the
emergency spare wheel, particularly prior to
long trips, and correct the pressure as neces-
sary (
Ypage 390). The value on the wheel or as
given in the "Wheels and tires" section is valid
(
Ypage 430).
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe
the time restriction on use as well as the speed
limitation specified on the emergency spare
wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
iWhen you are driving with the collapsible
spare wheel mounted, the tire pressure loss
warning system or the tire pressure monitor
cannot function reliably. Only restart the tire
pressure loss warning system or tire pressure
monitor when the defective wheel has been
replaced with a new wheel.
Vehicles with tire pressure monitor: after
mounting an emergency spare wheel, the sys-
tem may still display the tire pressure of the
removed wheel for a few minutes. The value
displayed for the mounted emergency spare
wheel is not the same as the current tire pres-
sure of the emergency spare wheel.
4Use of snow chains not permitted. Observe the notes in the "Snow chains" section.

Low outside temperatures
DEF freezes at a temperature of approximately
12 ‡ (-11 †). The vehicle is delivered from the
factory equipped with a DEF preheating system.
Winter operation can thus be guaranteed even
at temperatures below 12 ‡ (-11 †).
Additives
!Only use DEF in accordance with ISO
22241. Do not use additives with DEF and do
not dilute DEF with water. This may destroy
the BlueTEC exhaust gas aftertreatment sys-
tem.
Purity
!Impurities in DEF (e.g. due to other service
products, cleaning agents or dust) lead to:
Rincreased emission values
Rdamage to the catalytic converter
Rengine damage
Rmalfunctions in the BlueTEC exhaust gas
aftertreatment system
Assuring the purity of DEF is particularly impor- tant with respect to avoiding malfunctions in the
BlueTEC exhaust gas aftertreatment system.
If DEF is pumped out of the DEF tank, e.g. during
repair work, it must not be returned to the tank. The purity of the fluid can no longer be guaran-
teed.

Engine oil
General notes
!Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine
damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products (
Ypage 433).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil
filters that are approved for vehicles with main- tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
Or visit the website
http://bevo.mercedes-benz.com.
