The towing eye and a screwdriver are
located under a cover in the load
compartment.
Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Tyres
Self-sealing tyres This vehicle may have self-sealing
tyres. These tyres have a material
inside that can seal punctures up to
6 mm in the tread area.
The tyre may lose air pressure if the
sidewall is damaged or the tread
puncture is too large. If the Tyre
pressure monitoring system indicates the tyre pressure is low, inspect thetyre for damage and inflate it to the
recommended pressure. If the tyre is
Vehicle care235The available settings are:● Light for comfort pressure up to
three people.
● Eco for Eco pressure up to three
people.
● Max for full loading.
Auto learn function Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating
the wheels or exchanging the
complete wheel set and if one or more tyre pressure sensors were replaced.
After changing wheels, the vehicle
must be stationary for approx.
20 minutes before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
20 km/h. In this event, w can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message will be
displayed in the Driver Information
Centre.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheel size
If tyres of a different size than those
fitted at the factory are used, vehicle
performance, including braking, ride
and handling characteristics, stability
and resistance to rollover may be
affected. If the vehicle has electronic
systems such as antilock brakes,
rollover airbags, traction control,
electronic stability control, the
performance of these systems can
also be affected. It may be necessary
to reprogramme the speedometer as
well as the nominal tyre pressure and
make other vehicle modifications.
Vehicle care239Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the vehicle: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, press POWER m to switch on the
vehicle.
After the instrument cluster
initialises, the vehicle will use
power from the high voltage
battery to charge the 12-volt
battery.
3. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
4. Reverse above sequence exactly when removing leads.Towing
Towing the vehicleCaution
Incorrect towing of a disabled
vehicle may cause damage to the
vehicle. The disabled vehicle
should only be towed on a flatbed
car carrier.
Ensure the vehicle is only towed
by well trained technicians.
Insert a screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards. To prevent
damage, it is recommended to place
a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 230.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
240Vehicle careSwitch on the vehicle to release
steering wheel lock and to permit
operation of brake lights, horn and
windscreen wiper.
Set the shift lever of the electric drive unit to N.Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the vehicle 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.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
Insert cap at the bottom and close.
Towing another vehicle The vehicle is neither designed nor
intended to tow a trailer or another
vehicle.
Appearance care
Exterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use 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.
Washing The paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly. When using automatic vehicle
washes, select a programme that
includes waxing.
Do not apply waxes or polishes to uncoated plastic, vinyl, rubber,
decals, simulated wood, or flat paint
as damage can occur.Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.
If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wiper and 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.
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.
Vehicle care241Caution
Always use a cleaning agent with
a pH value of four to nine.
Do not use cleaning agents on hot surfaces.
Do not clean the engine compartmentwith a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Have the door hinges of all doors
greased by a workshop.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.
Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.Remove dirt residues from smearing wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
Ice residues, pollution and continuous
wiping on dry windows will damage or even destroy the wiper blades.
Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damageRectify minor paintwork damage with
a touch-up pen before rust forms. Have more extensive damage or rust
areas repaired by a workshop.
242Vehicle careUnderbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Do not spray cleaners directly on any switches or controls.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.
