ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the key in
steering lock position 2 and should go out
with the engine running.
When the ABS malfunction indicator lamp in the
instrument cluster comes on while the engine is
running, it indicates that the ABS has detected a
malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without
antilock assistance.
With the ABS malfunctioning, the BAS, ESP and 4-ETS+
are also switched off. Both malfunction indicator lamps
come on with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
See page 201 for notes on antilock brake system (ABS).Adjustable steering wheel – indicator lamp
The indicator lamp in the instrument cluster
comes on with the key in steering lock
position 2 and should go out with the engine
running.
If the indicator lamp does not go out after starting the
engine, the adjustable steering column is not properly
locked.
For locking the adjustable telescoping steering column,
see page 70.
AIRBAG OFF indicator lamp
The indicator lamp will light up for
approximately 6 seconds, extinguish, then
blink once, when you turn the key in
steering lock to position 1 or 2.
The 7 indicator lamp stays lit as long as a
BabySmart
TM compatible child seat is properly installed
on the front passenger seat. It indicates that the front
passenger airbag is switched off.

The jack is designed exclusively for jacking up the
vehicle at the jack take-up brackets built into either
side 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
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
end is fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient capacity
jackstands before working under the vehicle.

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
See your authorized Mercedes-Benz Light Truck Center
for information on tested and recommended rims and
tires for summer and winter operation. They can also
offer advice concerning tire service and purchase.Tire replacement
Front and rear tires should be replaced in sets.
Furthermore – in the event of tire replacement – the
optional regular size spare wheel should be used on the
rear axle. Rims and tires must be of the correct size and
type. For dimensions, see technical data on page 288.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torq ue of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on
page 288.
Wa r n i n g !
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

cluster displayPractical hintsCar care Index Rotating wheels
The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
dam age to t he tire bead s. For this reason, ch eck rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
page 250.

In the case of a flat tire or break-down, you may
temporarily use the space-saver spare wheel, while
observing the following restrictions:
•Do not exceed vehicle speed of 50 mph (80 km / h).
•Drive to the nearest repair facility to have the f lat
tire repaired or replaced as appropriate.
•Do not operate vehicle with more than one spare
wheel mounted.
For rim and tire specifications, refer to “Technical data”
on page 288.

To realize the total crumple zone in case of a rear end
collision, the space-saver spare wheel must be stored in
its holder with the tire deflated. Properly inflate the tire
prior to mounting it on the axle. See page 249 for
detailed instructions.
When storing the space-saver spare wheel in its holder,
tighten the three wheel bolts with a tightening torque of
37 ft.lb. (50 Nm).Space-saver tire (except ML 55 AMG)
