vThe yellow ESP® warn-
ing lamp comes on while
the engine is running.The ESP® has been switched off with the
ESP® switch or has been switched off due
to a malfunction.
Risk of accident!
When the ESP
® is switched off it will not
stabilize the vehicle if the system recog-
nizes that the vehicle starts to skid or that
a wheel is spinning.
The cruise control is deactivated and can-
not be switched on.
Switch the ESP® back on (page 96).
Exceptions: (
page 94).
If leaving the ESP® switched off, adapt your speed
and driving to the prevailing road, weather and
traffic conditions.
If the ESP
® cannot be switched on:
Continue driving with added caution.
Observer additional messages that may appear in
the multifunction display (
page 394).
Have the system checked at an authorized
Mercedes-Benz Center as soon as possible.
vThe yellow ESP® warn-
ing lamp flashes while
driving.The ESP® or traction control has come
into operation because of detected trac-
tion loss in at least one tire.
The cruise control is deactivatedWhen driving off, apply as little throttle as possi-
ble.
While driving, ease up on the accelerator.
Adapt your speed and driving to the prevailing
road, weather and traffic conditions.
Do not deactivate the ESP®.
Exceptions: (
page 94).
Failure to follow these instructions increases the risk
of an accident.

continuously.The TPMS detects a loss of pressure in at least
one tire.Carefully bring the vehicle to a
halt, avoiding abrupt steering and
braking maneuvers. Observe the
traffic situation around you.
Read and observe messages in
the multifunction display.
If the tire inflation pressure in the
respective tire(s) has (have) been
corrected, the combination low tire
pressure/TPMS malfunction telltale
goes out after a few minutes of
driving.

60 seconds and then stays
illuminated.There is a malfunction in the TPMS.Read and observe messages in
the multifunction display.
Have the TPMS checked at an au-
thorized Mercedes-Benz Center.
After the malfunction has been
remedied the combination low tire
pressure/TPMS malfunction telltale
goes out after a few minutes of
driving.

Warning!G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
Tire and Loading Information placard on the
driver’s door B-pillar (
page 334) or, if
available, the tire inflation pressure label on
the inside of the fuel filler flap (
page 320).
If your vehicle has tires of a different size
than the size indicated on the Tire and
Loading Information placard or the tire
inflation pressure label, you should deter-
mine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly underinflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly underinflated tire causes the tire to over-
heat and can lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately 1 minute
and then remain continuously illuminated.
This sequence will continue upon subse-
quent vehicle start-ups as long as the mal-
function exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.

or more tires.Check and correct tire inflation pressure as
required (
page 344).

Caution
Tire DefectOne or more tires are deflating.Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
If necessary, change the wheel (page 452).
Tire Pressure
Check TiresThe tire pressure in one or more
tires is already below the mini-
mum value.Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Check and adjust tire pressure as required
(
page 344).
If necessary, change the wheel (page 452).
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.
Warning!G
Follow recommended tire inflation
pressures.
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 com-
fort, wear unevenly, increase stopping dis-
tance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.

Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
