requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Tyre chains are only permitted on the

Vehicle care247Only 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.
● If necessary, place a chock under
the wheel diagonally opposite the wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .
● Remove the spare wheel 3 245.
● Never change more than one wheel 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.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
9Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Steel wheels with cover: Pull off the wheel cover with the
designated tool 3 234.
Alloy wheels: Disengage wheel
bolt caps with the designated tool
3 234.

7. Screw on the wheel bolts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each bolt in a crosswise
sequence. Tightening torque is
115 Nm.
If the vehicle is equipped with
alloy wheels, note that the wheel
bolts can also be used for the steel spare wheel. In this case, the
spare wheel is secured by the
conical contact of each bolt.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel bolt caps.
11. Stow the replaced wheel 3 245,
the vehicle tools 3 234 and the
adapter for the security wheel bolts.
12. Check the tyre pressure of the installed tyre and the wheel bolttorque as soon as possible.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

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

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.

vehicles equipped with AWD, all
four tyres must not be in contact
with the road.

damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 50 mph nor further than 60 miles. In all other
cases and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap with the flange into the
recess and fix cap by pushing.

Appearance care
Exterior care LocksThe locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use a de-icing agent only
when absolutely necessary, as this
has a degreasing effect and impairs
lock function. After using a de-icing
agent, have the locks regreased by a
workshop.

aggressive constituents which can
cause paint damage.If using a vehicle wash, comply with
the vehicle wash manufacturer's instructions. The windscreen wiperand rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Wax painted parts of the vehicle regularly.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
