Checking the tire pressures
Important safety notes
Observe the notes on tire pressure
(Ypage 338).
Information on air pressure for the tires on
your vehicle can be found:
Ron the vehicle's Tire and Loading
Information placard on the B-pillar
(Ypage 345)
Ron the tire pressure label on the fuel filler
flap (Ypage 165)
Rin the "Tire pressure" section
Runder "Tire pressure" (Ypage 338)
Checking tire pressures manually
To determine and set the correct tire
pressure, proceed as follows:
XRemove the valve cap of the tire that is to
be checked.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (Ypage 338).
XIf the tire pressure is too low, increase it to
the recommended value.
XIf the tire pressure is too high, release air
by pressing down the metal pin in the valve.
Use the tip ofapen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
XScrew the valve cap onto the valve.
XRepeatthese steps for the other tires.
Tire pressureloss warning system
(Canada only)
General notes
While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss inatire. If the speed
of rotation ofawheel changes asaresult of
aloss of pressure,acorresponding warning
message will appearinthe multifunction
display.
You can recognizethe tire pressure loss
warning by theRun Flat Indicator
Active Press 'OK' to Restartmessage
which appears in theServ.menu of the
multifunction display. Further information on
the message displaycan be found under
"Restarting the tire pressure loss warning
system" section (Ypage 342).
Important safety notes
The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Ypage 338).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you ofasudden loss of pressure, e.g. if the
tire is penetrated byaforeign object.Inthe
event ofasudden loss of pressure, bring the
vehicle toahalt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditionsare wintry.
Ryou are driving on sand or gravel.

Engine oil viscosity
Viscosity describes the flow characteristics
ofafluid. If an engine oil hasahigh viscosity,
this means that it is thick;alow viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside
temperatures. The table showsyou which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. asaresult
of aging, soot and fuel deposits. It is therefore
strongly recommendedthat you carry out
regular oil changes using an approved engine
oil with the appropriate SAE classification.
Brake fluid
GWARNING
The brake fluidconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluidistoo low,vaporpocketsmay form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There isarisk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Comply with the important safety notes for
service products when handling brake fluid
(Ypage 373).
The brake fluid change intervals can be found
