416 Practical hintsFlat tire
Clean contact surfaces of wheel and
wheel hub.
Guide the spare wheel onto the align-
ment bolt and push it on.
Insert the wheel bolts and tighten them
slightly.
!Wheel bolts2 must be used when
mounting the spare wheel with
collapsible tire. The use of any wheel
bolts other than wheel bolts2 for the
spare wheel with collapsible tire will
physically damage the vehicle’s
brakes. !To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.
Warning!
G
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts.

426 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Vehicles with automatic transmission*:
Do not tow-start vehicle.!Use flatbed or wheel lift/dolly equip-
ment with the SmartKey in the starter
switch in position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 88) and the automatic central
locking (
page 101).
!To be certain to avoid a possibility of
damage to the transmission, however,
we recommend the drive shaft be dis-
connected at the rear axle drive flange
for any towing beyond a short tow to a
nearby garage.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch
position0or1). Otherwise, the ESP
®
will immediately be engaged and will
apply the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever*
must be in positionN (manual trans-
mission: gear shift lever in neutral posi-
tion) and the SmartKey must be in
starter switch position1.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).
