21. Stow tyre repair kit under the front
seat.
Notice
The driving characteristics of the repaired tyre are severely affected,therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
The built-in safety valve opens at a
pressure of seven bar (102 psi).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 204.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-slippery surface. The
front wheels must be in the
straight-ahead position.
● Apply the parking brake and engage first gear or reverse gear
(manual transmission) or N
(manual transmission
automated).
● Switch off the air suspension system 3 139.
● Remove the spare wheel 3 209.
● Never change more than one wheel at a time.
● 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.
● 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 engine when the vehicle is raised on the jack.
● Clean wheel bolts/nuts and their threads before mounting the
wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Remove the wheel cover using the hook supplied. Vehicle tools
3 198.
Depending on vehicle, first
remove the bolt/nut covers by
hand then remove the wheel
cover, or press wheel cover at the points indicated by the arrows and
turn to release.

212Vehicle care● Do not drive faster than 50 mph.● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
The jump start terminal is located in
the engine compartment.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.
Do not start with a quick charger.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.
Caution
The air suspension system must
be switched off prior to jump
starting.
Air suspension 3 139.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster battery with the same voltage (12 volts). Its
capacity (Ah) must not be much
less than that of the discharged
vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 25 mm 2
.
● Do not disconnect the discharged
battery from the vehicle.

Vehicle care213● Switch off all unnecessaryelectrical consumers.
● Switch off the air suspension system 3 139.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.
● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the parking brake and engage neutral (manual
transmission) or N (manual
transmission automated).Jump start terminal
In the event of a discharged vehicle
battery, the jump start terminal
enables the vehicle to be started
without the need to access the battery inside the vehicle.
The jump start terminal is located in
the engine compartment and
identified by a " <" sign on the red
insulating cover. Lift the red insulating
cover to access the terminal
connector.
Ensure the red insulating cover is
latched back into position when not in
use.
Jump starting procedure
Depending on model, the jump start
terminal may be located at the left-
hand or right-hand side of the engine
compartment.

Vehicle care215Caution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Switch off the air suspension system 3 139.
Move the selector lever to neutral.
Release the parking brake.
Caution
Vehicles with manual
transmission automated: If neutral cannot be selected, the vehiclemust only be towed with the drive
wheels raised off the ground.
The vehicle should always be
towed with the ignition switched
off.
Manual transmission automated
3 149.Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the air recirculation system 3 116 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and refit the cover.
Towing another vehicle
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
Caution
The rear towing eye must only be
used for towing and not recovering a vehicle.
