!To prevent damage, always disengage
trunk floor handle from upper edge of
trunk and lower trunk floor before
closing the trunk lid.Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted.
The Minispare wheel should only be used
temporarily, and should be replaced with a
regular road wheel as quickly as possible.

Spare wheel bolts
1Wheel bolt for light alloy rims
2Wheel bolt for Minispare wheel,
collapsible tire, or other steel rims
(located in trunk with spare wheel)
!Wheel bolts2 must be used when
mounting the Minispare wheel,
collapsible tire, or other steel rims. The
use of any wheel bolts other than wheel
bolts2 for the Minispare wheel,
collapsible tire, or other steel rims will
physically damage the vehicle’s
brakes. Warning!
G
Make sure to use the original length wheel
bolts when remounting the original wheel
after it has been repaired.

418 Practical hintsFlat 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 trunk.Lowering the vehicle

Lower vehicle by turning crank
counterclockwise until vehicle is
resting fully on its own weight.

Remove the jack.1 - 5Wheel bolts

Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1to5), until all bolts are
tight. Observe a tightening torque
of 80 lb-ft (110 Nm).
Warning!
G
Follow recommend 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
Vehicles with collapsible tire
(CLK 55 AMG only):
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 416) before
lowering the ve-
hicle.

Rims and tires
Rims and tires
Only use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as

poor handling characteristics


increased noise


increased fuel consumption
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar. Some vehicles may have sup-
plemental tire pressure information for
driving at high speeds (
page 326) or
for vehicle loads less than the maxi-
mum loaded vehicle condition. If such
information is provided, it can be found
on the placard located on the inside of
the fuel filler flap. The tire inflation
pressure should be checked regularly
and should only be adjusted on cold
tires. Follow tire manufacturer’s main-
tenance recommendation included
with vehicle.

ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.
Telematics*
A combination of the terms “telecom-
munications” and “informatics”.Tightening torque
Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.
Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction
Force exerted by the vehicle on the
road via the tires.VIN
(V
ehicle I
dentification N
umber)
The number set by the manufacturer
and placed on the body to uniquely
identify each vehicle produced.
Voice control system*
