H
Combination low tire pres-
sure/TPMS malfunction telltale
for the TPMS* illuminates con-
tinuously.
The Advanced 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.

Take note of the messages in the multi-
function display.
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
combination low tire pressure/TPMS mal-
function telltale goes out after few minutes
driving.
H
Combination low tire pres-
sure/TPMS malfunction telltale
for the Advanced TPMS* flashes
60 seconds and then stays illu-
minated.
There is a malfunction in the Advanced
TPMS*.

Take note of the messages in the multi-
function display.

Have the Advanced TPMS* checked by
an authorized Mercedes-Benz Light
Truck Center.
After the malfunction has been remedied
the combination low tire pressure/TPMS
malfunction telltale goes out after few
minutes driving.

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
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should consult the appropriate section
of this owner’s manual to determine the
proper tire inflation pressure). When the low
tire pressure telltale is illuminated, one or
more of your tires is significantly under-in-
flated. You should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-infla-
tion also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s han-
dling and stopping ability.
Your vehicle has also been equipped with a
TPMS malfunction telltale to indicate when
the system is not operating properly. When
the malfunction telltale is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS mal-
functions may occur for a variety of reasons,
including the installation of incompatible
replacement tires on the vehicle. Always
check the TPMS malfunction telltale after
replacing one or more tires on your vehicle
to ensure that the replacement tires are
compatible with the TPMS.

Tire pressure
Check tires
The Run Flat Indicator indicates that
the pressure is too low in one or more
tires.

Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. Observe the traffic sit-
uation around you.

Check and adjust tire inflation pressure as required
(page 348).

If necessary, change the wheel (
page 457).

Reactivate the Run Flat Indicator after adjusting the tire
inflation pressure values (
page 350).

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.

Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Turn the steering wheel so that the
front wheels are in a straight ahead po-
sition.

Set the parking brake.

Shift automatic transmission to park
positionP.
Vehicles with Air suspension package*:

Do not open or close a door or tailgate
while mounting the spare wheel.
Vehicles with SmartKey:

Turn off the engine (
page 34).

Remove the SmartKey from the starter
switch.Vehicles with KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* button once
(page 63).

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.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a mounted
Minispare wheel. Adapt your driving style
accordingly.
The Minispare wheel is for temporary use
only. When driving with a Minispare wheel
mounted, ensure proper tire pressure and
do not exceed a vehicle speed of
50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
Minispare 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
Minispare wheel is mounted.
iOpen doors only when conditions are
safe to do so.

Only use tires which have been specifi-
cally developed for your vehicle and
tested and approved by
Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to pro-
vide best possible performance in con-
junction with the driving safety
systems on your vehicle such as ABS or
ESP
® and can be identified by finding
the following on the tire’s sidewall:

Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.
!Using tires other than those approved
by Mercedes-Benz can have detrimen-
tal effects, such as

poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Light Truck Center.
A placard with the recommended tire
inflation pressure is located on the
driver’s door B-pillar. Some vehicles
may have supplemental tire inflation
pressure information for driving at high
speeds (
page 345) or for vehicle
loads less than the maximum loaded
vehicle condition. If such information is
provided, it can be found on the placard
located 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 recom-
mendation included with vehicle.
