Practical hints
Flat tire
̈ Detach the electric air pump.
̈ Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the cargo
compartment.
Lowering the vehicle
̈ Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
̈ Remove the jack.
1-5 Wheel bolts
̈ 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).
Warning! G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Warning! G
Vehicles with collapsible tire
(ML 63 AMG only):
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
୴ page 502) before lowering the
vehicle.
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).
