Use Parking Guidance for parking spaces:
Rparallel to the direction of travel
Ron straight roads, not bends
Rthat are on the same level as the road, i.e.not on the pavement, for example. ParkingAssist PARKTRONIC may not detect flatcurbs
Parking tips:
Ron narrow roads, drive as closely as possiblepast the parking space
Rparking spaces that are littered or over-grown might be identified or measuredincorrectly
Rparking spaces that are partially occupiedby trailer drawbars might not be identifiedas such or be measured incorrectly
Rsnowfall or heavy rain may lead to a parkingspace being measured inaccurately
Rpay attention to the Parking AssistPARKTRONIC warning messages during theparking procedure (Ypage 155)
Rwhen transporting a load which protrudesfrom your vehicle, you should not use Park-ing Guidance
Rnever use Parking Guidance with snowchains or an emergency spare wheel moun-ted
RMake sure that the tire pressures are alwayscorrect. This has a direct effect on the steer-ing characteristics.
RThe way your vehicle is positioned in theparking space after parking is dependent onvarious factors. These include the positionand shape of the vehicles parked in frontand behind it and the conditions of the loca-tion. In some cases, Parking Guidance mayguide you too far or not far enough into aparking space. In some cases, it may alsolead you across or onto the curb. If neces-sary, cancel the parking procedure withParking Guidance.

Important safety notes
GWARNING
If you install wheels and tires with incorrect
dimensions, the service brake or wheel sus-
pension components may be damaged.
There is a risk of an accident.
Always replace wheels and tires with ones
that comply with the specifications of the
original part.
When replacing wheels, pay attention to the:
RDesignation
RModel
When replacing tires, pay attention to the:
RDesignation
RManufacturer
RModel
GWARNING
A flat tire will severely affect the driving
characteristics as well as the steering and
braking of the vehicle. There is a risk of an
accident.
Tires without run-flat characteristics:
RDo not drive on with a flat tire.
RChange the flat tire immediately with an
emergency spare wheel or spare wheel.
Alternatively, consult a qualified specialist
workshop.
Tires with run-flat characteristics:
RObserve the information and warning
notes on MOExtended tires (run-flat tires).
Accessories that are not approved for yourvehicle by Mercedes-Benz or are not beingused correctly can impair the operating safety.
Before purchasing and using non-approvedaccessories, visit a qualified specialist work-shop and ask about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Further information regarding wheels and tirescan be found under "Wheel/tire combinations"(Ypage 292).
You can ask for information regarding permit-ted wheel/tire combinations at an authorizedMercedes-Benz Center.
Information on tire pressure can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side(Ypage 279)
Rin the tire pressure table in the fuel filler flap(Ypage 133)
Rin the "Tire pressure" section
Operation
Information on driving
Check the tire pressure when the vehicle isheavily laden and adjust prior to a trip.
While driving, pay attention to vibrations,noises and unusual handling characteristics,e.g. pulling to one side. This may indicate thatthe wheels or tires are damaged. If you sus-pect that a tire is defective, reduce your speedimmediately. Stop the vehicle as soon as pos-sible to check the wheels and tires for dam-age. Hidden tire damage could also be causingthe unusual handling characteristics. If youfind no signs of damage, have the tires andwheels checked at a qualified specialist work-shop.
When parking your vehicle, make sure that thetires do not get deformed by the curb or otherobstacles. If they cannot be avoided, driveover obstacles such as curbs slowly and at anobtuse angle. Otherwise, you may damage thewheels or tires.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tires regularly for signs of dam-
age and replace any damaged tires immedi-
ately.
Operation267
Wheels and ti res
Z

Check wheels and tires for damage at leastonce a month. Check wheels and tires afterdriving off-road or on rough roads. Damagedwheels can cause a loss of tire pressure. Payparticular attention to damage such as:
Rcuts in the tires
Rpunctures in the tires
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and thecondition of the tread across the whole widthof all tires (Ypage 268). If necessary, turn thefront wheels to full lock in order to inspect theinner side of the tire surface.
All wheels must have a valve cap to protectthe valve against dirt and moisture. Do notmount anything onto the valve other than thestandard valve cap or other valve capsapproved by Mercedes-Benz for your vehicle.Do not use any other valve caps or systems,e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tiresparticularly prior to long trips. Adjust the tirepressure as necessary (Ypage 270).
Observe the notes on the emergency sparewheel (Ypage 293).
The service life of tires depends, among otherthings, on the following factors:
RDriving style
RTire pressure
RDistance covered
Notes on tire tread
GWARNING
If there is insufficient tire tread, the tire trac-
tion decreases. The tire tread is no longer
able to dissipate water. This increases the
risk of hydroplaning when the road surface
is wet, particularly when the vehicle's speed
is not adapted to the road conditions. There
is a risk of an accident.
When the tire pressure is too high or too
low, tires may wear differently at different
points on the tire tread. Therefore, regularly
check the tire tread depth and the condition
of the tread across the whole width of all
tires.
Minimum tire tread depth on:
RSummer tires:

Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
For safety reasons, Mercedes-Benz recom-mends that you only use snow chains thathave been specially approved for your vehicleby Mercedes-Benz, or are of a correspondingstandard of quality. For more information,please contact a qualified specialist workshop.
If you intend to mount snow chains, pleasebear the following points in mind:
RSnow chains may not be mounted on allwheel/tire combinations. Permissiblewheel-tire combinations (Ypage 292).
ROnly use snow chains when driving on roadscompletely covered by snow. Remove thesnow chains as soon as possible when youcome to a road that is not snow-covered.
RLocal regulations may restrict the use ofsnow chains. Observe the appropriate regu-lations if you wish to mount snow chains.
RDo not exceed the maximum permissiblespeed of 30 mph (50 km/h).
You may wish to deactivate ESP®when pullingaway with snow chains installed (Ypage 61).You can thereby allow the wheels to spin in acontrolled manner, achieving an increaseddriving force (cutting action).

Tire pressure
Tire pressure specifications
Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires
including the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning a long journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Informationplacard and tire pressure table shown here areexamples. Tire pressure specifications arevehicle-specific and may deviate from the datashown here. The tire pressure specificationsthat are valid for your vehicle can be found onthe Tire and Loading Information placard andtire pressure table on the vehicle.
General notes
The recommended tire pressures for the tiresmounted at the factory can be found on thelabels described here.
Operation with an emergency spare wheel:information on operation with an emergencyspare wheel can be found in the general notesin the "Emergency spare wheel" section(Ypage 294).
Further information on tire pressures can beobtained at a qualified specialist workshop.

Wheels and tires

Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
RCheck the tire for foreign objects.
RCheck whether the wheel is losing air or
the valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
GWARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded
and malfunction, which can cause tire pres-
sure loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss.
There is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check thetire pressure. The outer appearance of a tiredoes not permit any reliable conclusion aboutthe tire pressure. On vehicles equipped withthe electronic tire pressure monitor, the tirepressure can be checked in the on-board com-puter.
The tire temperature and pressure increasewhen the vehicle is in motion. This is depend-ent on the driving speed and the load.
Therefore, you should only correct tire pres-sures when the tires are cold.
The tires are cold:
Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursand
Rif the vehicle has not been driven furtherthan 1 mile (1.6 km)
The tire temperature changes depending onthe outside temperature, the vehicle speedand the tire load. If the tire temperaturechanges by 18 ‡ (10 †), the tire pressurechanges by approximately 10 kPa (0.1 bar/1.5 psi). Take this into account when checking
the pressure of warm tires. Only correct thetire pressure if it is too low for the currentoperating conditions. If you check the tirepressure when the tires are warm, the result-ing value will be higher than if the tires werecold. This is normal. Do not reduce the tirepressure to the value specified for cold tires.The tire pressure would otherwise be too low.
Observe the recommended tire pressures forcold tires:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side
Rin the tire pressure table on the inside of thefuel filler flap
Rprinted in yellow on the rim of the emer-gency/collapsible spare wheel (dependingon vehicle equipment)
Underinflated or overinflated tires
Underinflated tires
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addi-
tion, they also suffer from excessive and/or
irregular wear, which can severely impair the
braking properties and the driving character-
istics. There is a risk of an accident.
Avoid tire pressures that are too low in all
the tires, including the spare wheel.
Underinflated tires may:
Roverheat, leading to tire defects
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
Overinflated tires
GWARNING
Tires with excessively high pressure can
burst because they are damaged more eas-
ily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
272Tire pressure
Wheels and ti res

Avoid tire pressures that are too high in all
the tires, including the spare wheel.
Overinflated tires may:
Rincrease the braking distance
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on ride comfort
Rbe more susceptible to damage
Maximum tire pressures
CExample: maximum permissible tire pres-sure
Never exceed the maximum permissible tireinflation pressure. Always observe the recom-mended tire pressure for your vehicle whenadjusting the tire pressure (Ypage 270).
iThe actual values for tires are vehicle-spe-cific and may deviate from the values in theillustration.
Checking the tire pressures
Important safety notes
The tire pressure monitor does not warn youof:
Rincorrectly set tire pressure
Rsudden loss of tire pressure, e.g. from a for-eign object that has penetrated the tire
Observe the notes on tire pressure(Ypage 270).
Information on air pressure for the tires onyour vehicle can be found:
Ron the vehicle's Tire and Loading Informa-tion placard on the B-pillar
Ron the tire pressure table in the fuel fillerflap
Rin the "Tire pressure" section
Checking tire pressures manually
To determine and set the correct tire pressure,proceed as follows:
XRemove the valve cap of the tire that is tobe checked.
XPress the tire pressure gauge securely ontothe valve.
XRead the tire pressure and compare it to therecommended value on the Tire and LoadingInformation placard or the tire pressuretable (Ypage 270).
XIf the tire pressure is too low, increase thetire pressure to the recommended value.
XIf the tire pressure is too high, release air.To do so, press down the metal pin in thevalve, using the tip of a pen for example.Then check the tire pressure again using thetire pressure checker.
XScrew the valve cap onto the valve.
XRepeat these steps for the other tires.
Tire pressure loss warning system
(Canada only)
General notes
While the vehicle is in motion, the tire pres-sure loss warning system monitors the set tirepressure using the rotational speed of thewheels. This enables the system to detect sig-nificant pressure loss in a tire. If the speed ofrotation of a wheel changes as a result of aloss of pressure, a corresponding warningmessage will appear in the multifunction dis-play.
You can recognize the tire pressure loss warn-ing by theRun Flat Indicator ActiveRun Flat Indicator ActivePress 'OK' to RestartPress 'OK' to Restartmessage whichappears in theServ.Serv.menu of the multifunc-tion display. Information on the message dis-play can be found in the "Restarting the tire
