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 tire inflation pressures.
Do not overinflate tires. Overinflating 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
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
air pump (
page 483) 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).


501 Practical hints
Towing the vehicle
Installing towing eye bolts
The front towing eye is located behind a
cover on the passenger side below the
front bumper.
1Towing eye cover
iThe vehicle cannot be started via
tow-start.iIf the battery is disconnected or dis-
charged, the automatic transmission
will remain locked in positionP and the
SmartKey will not turn in the starter
switch. For more information, see “Bat-
tery” (
page 487) and “Jump starting”
(
page 496).
!When towing the vehicle with all wheels
on the ground, note the following:
With the automatic central locking
activated and the ignition in position2
(page 38), the vehicle doors lock if
the left front wheel is turning at a speed
of approx. 9 mph (15 km / h) or above.
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 130).
Switch off the tow-away alarm
(
page 107).
Towing of the vehicle should only be
done using the towing eye. Never
attach tow cable, tow rope or tow rod
to vehicle chassis, frame or suspension
parts.

The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as

vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.

A combination of the terms “telecom-
munications” and “informatics”.
