spare tire MERCEDES-BENZ GLK SUV 2008 Owners Manual

Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
i An emergency spare wheel* may also be
fitted against the direction of rotation. Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less as they will no
longer provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the steering wheel so that you can see
the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The valid value for the "Minispare" emer-
gency spare wheel* is stated on the spare
wheel and in the technical data section. G
Risk of accident
Tyre pressure that is either too high or too low
has a negative effect on the vehicle’s driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. G
Risk of accident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz has been fitted on the
tyre valve.
Tyre pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident.
If possible, you should only correct tyre pres-
sures when the tyres are cold. Depending on
the ambient temperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 °C.
Take this into account when checking the
pressure of warm tyres and only correct it if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R increase the likelihood of tyre damage
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning) 152 Ty

Vehicle tool kit, jack, TIREFIT kit and
collapsible spare wheel* The vehicle tool kit, TIREFIT kit and jack can
be found on the left-hand side (when viewed
in the direction of travel) of the stowage well
under the luggage compartment floor.
X
Open the stowage well under the luggage
compartment floor (Y page 136). G
Risk of injury
The jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed.
You must use axle stands if you are carrying
out work on the vehicle.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
Otherwise, the jack will not be able to achieve
its load-bearing capacity due to the restricted
height.
Do not start the engine at any time while a
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or if a door or the tailgate is opened or closed) and you could be
seriously injured.
i When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 222).

Flat tyre equipment variants
Your vehicle may be equipped with:
R a TIREFIT kit (Y page 175)
R a collapsible emergency spare
wheel* (Y page 175) Preparing the vehicle
X Stop your vehicle as far away from traffic
as possible on solid, non-slippery, level
ground.
X Switch on the hazard warning lamps.
X Firmly depress the parking brake.
X Move the selector lever to P.
X All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area whilst a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier. X
Switch off the engine.
X Remove the key from the ignition lock.
X Get out of the vehicle.
X Close the driver's door.
X Place the warning triangle (Y page 174) at
a suitable distance. Observe legal require-
ments. Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT at outside temperatures
down to -20 †. G
Risk of accident
In the following situations, your safety is at
particular risk and tyre sealant is unable to
provide breakdown assistance:
R if there are cuts or punctures in the tyre
greater than 4 mm
R if the wheel rim is damaged
R if you have driven at very low tyre pressures
or on a flat tyre
Do not drive any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
X Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove TIREFIT, the accompanying "max.
80 km/h" sticker and the electric air pump
from the stowage well underneath the lug-
gage compartment floor (Y page 175).222 Flat tyrePractical advice

sure gauge F.
X Drive to the nearest workshop and have the
tyre changed there.
X Have the TIREFIT kit replaced as soon as
possible at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre. G
Risk of accident
Do not exceed the maximum speed of
80 km/h.
The "max. 80 km/h" label must be affixed in
the driver's field of vision.
The vehicle's handling characteristics may be
affected. H
Environmental note
Have the used TIREFIT kit disposed of profes-
sionally, e.g. at a Mercedes-Benz Service
Centre.
X Have the TIREFIT kit replaced every four
years at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. Changing a wheel/fitting the emer-
gency spare wheel* G
Risk of accident
The wheel dimensions and tyre size of the
emergency spare wheel* may differ from
those of the standard wheels.
The handling characteristics of your vehicle
will change if you fit an emergency spare
wheel*. Adapt your style of driving accord-
ingly.
You may only use the emergency spare
wheel* for a short while. Do not exceed the
maximum speed of 80 km/h and do not deac-
tivate ESP ®
.
Never drive the vehicle with more than one
emergency spare wheel* fitted. G
Risk of accident
Have the emergency spare wheel* replaced
as soon as possible at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 222).
X If a trailer is coupled, uncouple it.
X Place the wheels in the straight-ahead posi-
tion.
X Take the following from the stowage well
beneath the luggage compartment floor:
R
