2008 MERCEDES-BENZ S-Class inflation pressure

702 Practical hintsWhat to do if …?Display
Possible cause/consequence
Possible solution
Check Tires
The pressure is too low in one or more tires.
The respective tire is shown in the multi-
function display.

Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.

Engage the electronic parking brake
(page 422).

Check and adjust tire inflation pressure as
required (
page 593).

If necessary, change the wheel (
page 723).
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire will cause excessive
heat build-up and possibly a fire.
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly affect handling and fuel economy, and are
more likely to fail from being overheated. Do
not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.

Display
Possible cause/consequence
Possible solution
Wheel Sensor(s)
Missing
One or more sensors malfunction (e.g. bat-
tery in one or more wheel sensor is empty).
One or more wheels without wheel sensors
mounted (e.g. spare tire).
No pressure value is shown on the multi-
function display for the tire in question.

Have the Advanced TPMS checked by an au-
thorized Mercedes-Benz Center.

Have the wheel sensors installed by an
authorized Mercedes-Benz Center.
The tire pressure for the respective tire is
shown in the multifunction display after a few
minutes of driving.
Tire Pressure
Please Rectify
The pressure is too low in one or more tires.
Or the tire pressures of the individual
wheels differ too radically from one anoth-
er.

Check and adjust tire inflation pressure as
required (
page 593).

Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.

Turn on the hazard warning flasher
(page 405).

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Shift the automatic transmission to
park positionP.

Engage the electronic parking brake.

Turn off the engine.

Have any passenger exit the vehicle at
a safe distance from the roadway.

Vehicles with SmartKey: Remove the
SmartKey from the starter switch.
Vehicles with KEYLESS-GO*: Open the
driver’s door (this puts the starter
switch in position0, same as with the
SmartKey removed from the starter
switch). The driver’s door then can be
closed again.
Remove the KEYLESS-GO*
start/stop button from the starter
switch.
Mounting the spare wheel
i
Open the door only when conditions are safe
to do so.
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and
do not exceed a vehicle speed
of 50 mph (80 km/h).
Contact the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a spare
wheel is mounted.

728 Practical hintsFlat tire6Wheel wrench
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).

Fully collapse the jack, with handle
folded in (storage position),
(page 706).

Store the jack and the other vehicle
tools in the designated storage space
underneath the trunk floor
(page 705).
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).i
Vehicles with Advanced TPMS:
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.

754 Technical dataRims and tires!
Only use tires which have been tested and
approved by Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to provide best
possible performance in conjunction with the
driving safety systems on your vehicle such as
ABS or ESP
®. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding the
following on the tire’s sidewall:


MO = M
ercedes-Benz O
riginal equipment
tires
AMG vehicles:
Does not apply to all approved tires on AMG
vehicles. For information on tested and
approved tires for AMG vehicles, contact an
authorized Mercedes-Benz Center.
Using tires other than those approved by
Mercedes-Benz may result in damage that is not
covered by the Mercedes-Benz Limited
Warranty.
!
Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as


poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the
result.
i
Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. A placard with the recommended tire in-
flation pressures is located on the driver’s door
B-pillar (
page 585). Some vehicles may have
supplemental tire inflation pressure information
for driving at high speeds (
page 591) or for ve-
hicle loads less than the maximum loaded
vehicle condition (
page 598). If such informa-
tion is provided, it can be found on the placard lo-
cated on the inside of the fuel filler flap. The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
i
The following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Appearance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. Contact an authorized
Mercedes-Benz Center for more information.

Please compare the recommended tire
inflation pressure for your vehicle with the tire
inflation pressure on the yellow label located on
the spare wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the spare
wheel tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.
i
Please note that the tire inflation pressure of
the spare tire differs from the tire inflation pres-
sure of the road tires.
