Tools
Vehicles with spare wheel
The jack with wheel wrench, the tools,
an extension bolt for securing a
damaged wheel and the towing eye
are placed in the tool box below the
spare wheel in the load compartment. Spare wheel 3 288.

platform centrically under the relevant vehicle jacking point.
Spare wheel
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations. In this case a permissible maximum speed applies, even
though no label at the spare wheel
indicates this.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. Take curves slowly. Do not
use for a long period of time.Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Caution
If driving with a temporary spare
wheel, active emergency braking
has to deactivated.
The spare wheel is located in the load
compartment beneath the floor
covering.
To remove: 1. Open the floor cover.
2. The spare wheel is secured with a
wing nut. Turn wing nut
anticlockwise and remove the
spare wheel.
Under the spare wheel there is the
box with vehicle tools.
3. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
turning right back the wing nut and close the floor cover.
4. After wheel change back to full size wheel, place the spare wheel
outside up in the well and secure
with the wing nut.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Fitting the spare wheel
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight-
ahead position.
● Apply the parking brake and engage first gear, reverse gear or
P .
● Remove the spare wheel.
Page 291 of 345

Vehicle care289● Never change more than onewheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Clean wheel nuts and thread with
a clean cloth before mounting the wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Steel wheels with cover: Pull off the wheel cover.
Alloy wheels: Disengage wheel
nut caps with a flat screwdriver
and remove. To protect the wheel paint and the cap, wrap a cloth
around the screwdriver tip.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
nut by half a turn.
The wheels might be protected by
locking wheel nuts. To loosen
these specific nuts, first attach the adapter for the locking wheel nuts
onto the head of the nut before
installing the wheel wrench. The
adapter is located in the glovebox.
3. Ensure the jack is correctly positioned under the relevant
vehicle jacking point.

290Vehicle careSome versions have sill panels
with covered vehicle jacking points: pull out the cover at the
respective jacking point firstly.
4. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
5. Unscrew the wheel nuts. 6. Change the wheel.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each nut in a crosswise
sequence. Tightening torque is
140 Nm for all models except GSi.
GSi models have a tightening
torque of 190 Nm
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Install vehicle jacking point cover.
12. Stow and secure the replaced wheel, the vehicle tools 3 275 and
the adapter for the locking wheel
nuts 3 73.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
Stowing the replaced full size
wheel in the spare wheel well
Secure a damaged full size wheel facing upwards with the wing nut in
the spare wheel well after mounting
an extension bolt on the thread bolt.
The extension bolt is stowed with the
vehicle tools 3 275. To secure the
wheel:

Vehicle care291
1. Stick the extension bolt onto thethread bolt.
2. Store the damaged wheel outside
up in the spare wheel well and
secure it by turning the wing nut
clockwise on the extension bolt.
9 Warning
Storing a jack, a wheel or other
equipment in the load
compartment could cause injury if they are not fixed properly. During
a sudden stop or a collision, looseequipment could strike someone.
Store wheel, jack and tools always
in the original storage location and secure them by fixing.
Spare wheel with directional tyre
Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Drive particularly carefully on wet
and snow-covered road
surfaces.
Jump starting
Do not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
