419 Practical hints
Flat tire
PressI on electric air pump switch2.
The electric air pump switches on and
inflates the collapsible tire.
Inflate the collapsible tire to approxi-
mately 51 psi (3.5 bar).
This takes about 5 minutes. Air
hose4 and union nut5 can become
hot during inflation. Exercise proper
caution to avoid burning yourself when
using the equipment.
Press0 on electric air pump switch2.
Turn the SmartKey in the starter switch
to position0.
The electric air pump is switched off.
If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire
inflation pressure using the vent screw
on air hose4.
Detach the electric air pump.
Reinstall tire valve cap.
Store electrical plug3 and air
hose4 behind flap 1 and place the
electric air pump back in the trunk.
Lower the vehicle (page 420).
!Compare the recommended tire inflation
pressure for your vehicle with the tire inflation
pressure on the yellow label located on the spare
wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the
collapsible tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.
!Do not operate the electric air pump longer
than 6 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again
after it has cooled off.Warning!G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.

Flat tire
Lowering the vehicle
Lower vehicle by turning the crank
counterclockwise until vehicle is
resting fully on its own weight.
Remove the jack.
1-5 Wheel bolts
Tighten the five wheel bolts evenly in
the direction of the arrow, following the
diagonal sequence illustrated
(1to5), until all bolts are tight.
Observe a tightening torque of
80 lb-ft (110 Nm).
Fully collapse the jack.
Place the vehicle tool kit, electric air
pump, and the jack back in the storage
compartment underneath the trunk
floor.
Wrap the damaged wheel in the protec-
tive sheet provided with the vehicle
tool kit and put the wheel in the trunk.
For information on storing the spare wheel
in the trunk after it has been replaced by a
regular road wheel, see “Storing the spare
wheel with collapsible tire” (
page 392).
Warning!G
Inflate the collapsible tire using the electric
pump (
page 418) 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
80 lb-ft (110 Nm).
iThe flat tire may be transported in the trunk
when the retractable hardtop is closed.

429 Practical hints
Towing the vehicle
Installing towing eye bolt
The towing eye bolt is supplied with the ve-
hicle tool kit, located in the compartment
underneath the trunk floor (
page 389).
The towing eyes are located on the passen-
ger side in the front and rear bumper.
Take vehicle tool kit out of trunk
(
page 389).
Front cover

!Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach a tow cable, tow rope or tow rod to
the vehicle chassis, frame or suspension parts.
iWhen towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2, the
vehicle doors lock if the left front wheel as well
as the right rear wheel are turning at vehicle
speeds of approximately 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 102).
iTo signal turns while being towed with the
hazard warning flasher in use, switch on ignition
and activate the combination switch for the left
or right turn signal in the usual manner – only the
selected turn signal will operate.
Upon canceling the turn signal, the hazard warn-
ing flasher will operate again.
iThe gear selector lever* will remain locked
in positionP (vehicles with automatic transmis-
sion*) and the SmartKey will not turn in the
starter switch if the battery is disconnected or
discharged. For more information, see “Battery”
(
page 422) or “Jump starting” (page 426).
Vehicles with automatic transmission*:
For information on manual unlocking of gear
selector lever, see (
page 396).
