G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: make sure the
vehicle’s on-board electronics have
status
0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
!Never open the hood when the wiper
arms are folded forward.
Hold on to the wiper when folding the
wiper arm back. If released, the force
of the impact from the tensioning
spring could crack the windshield.

Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flasher
(page 131).

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Set the parking brake (
page 55).

Move the gear selector lever toP.
Vehicles with SmartKey:

Turn off the engine (
page 56).

closed again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling characteristics change
when driving with a spare wheel mounted.
Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
iOpen door only when conditions are
safe to do so.

413 Practical hints
Flat tire
Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(page 412).
Vehicles with Minispare wheel:

Take the wheel wrench, the wheel
bolts, and the jack out of the trunk
(page 389).

Take the Minispare wheel out of the
trunk (
page 393).
Vehicles with collapsible tire
(CLK 55 AMG only):

Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the trunk (
page 390).Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One wheel chock is included with the
vehicle tool kit (
page 389).
When changing wheel on a level surface:

Place the wheel chock in front of and
another sizable object behind the
wheel that is diagonally opposite to the
wheel being changed.
When changing wheel on a hill:

Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the other axle.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

414 Practical hintsFlat tire1Wheel wrench
On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with
wrench 1).
The jack take-up brackets are located
directly behind the front wheel housings
and in front of the rear wheel housings.2Jack
3Take-up bracket

Place jack2 on firm ground.

Position jack2 under take-up
bracket3 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.

Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while
vehicle is raised.Warning!
G
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle.

Never start the engine when the vehicle
is raised.


Never lie down under the raised vehicle.

bolt1 supplied in the tool kit.

Remove the remaining bolts.

Remove the wheel.Mounting the spare wheel
1Wheel bolt for light alloy rims
2Wheel bolt for Minispare wheel,
collapsible tire, or other steel rims
(located in trunk with spare wheel)

Clean contact surfaces of wheel and
wheel hub.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolts
and wheel hub threads.
!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.
!To avoid paint damage, place wheel flat
against hub and hold it there while
installing first wheel bolt.Warning!
G
Always replace wheel bolts that are
damaged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact
an authorized 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.
Make sure to use the correct wheel bolts.

vehicle is raised. Otherwise the vehicle
could fall off the jack.
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
vehicle.

Take the electric air pump out of the
trunk (
page 391).
1Flap
2On/off switch
3Electrical plug
4Air hose with pressure gauge and vent
screw
5Union nut

Open flap 1 on electric air pump.

Pull out electrical plug 3 and air hose
with pressure gauge 4.

Remove the valve cap from the
collapsible tire valve.

Screw air hose 4 onto the collapsible
tire valve.

Insert electrical plug 3 into vehicle
cigarette lighter socket.

Turn the SmartKey in the starter switch
to position1.

Press I on electric air pump switch 2.
The electric air pump should now
switch on and inflate the collapsible
tire.

Inflate the tire to approximately 36 psi
(2.5 bar).
This takes about five minutes for the
collapsible tire. Air hose 4 and union
nut5 can become hot duration infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

Press 0 on electric air pump switch 2.

Turn the SmartKey in the starter switch
to position0.

If the tire pressure is above 36 psi
(2.5 bar), release excess tire pressure
using the vent screw.!Do not operate the electric air pump
longer than six minutes without inter-
ruption. Otherwise it may overheat.
You may operate the electric air pump
again after it has cooled off.


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.
