Vehicle care237Temporary spare wheel
The use of tyre chains is not permitted on the temporary spare wheel.Jump starting
Do not start with quick charger.
If the 12 V vehicle battery is empty, the vehicle can be started using jump leads and the vehicle battery of
another vehicle. Jump starting only
works when the high voltage battery
is charged.9 Danger
The high voltage battery cannot be
jump started either with another
vehicle or battery charger.
Personal injury, death, or damage
to the vehicle could result.
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.
9 Warning
Never jump start another vehicle
by using the terminals located in
the engine compartment.
This could cause a fuse to
overload in the vehicle.
● Never expose the 12 V vehicle battery to naked flames or
sparks.
● A discharged 12 V vehicle battery
can already freeze at a
temperature of 0 °C. Defrost the
frozen 12 V vehicle battery
before connecting jump leads.
● Wear eye protection and protective clothing when
handling a 12 V vehicle battery.
Page 240 of 267

238Vehicle care● Use a booster vehicle batterywith the same voltage (12 V). Itscapacity (Ah) must not be muchless than that of the discharged
12 V vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
.
● Do not disconnect the discharged
12 V vehicle battery from the
vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the 12 V 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, shift selector lever into P.
● Open the positive terminal protection cap of both batteries.Battery terminals in the engine
compartment
The battery terminals to jump start the
vehicle are located in the engine
compartment.
The positive battery terminal is
located below a cover. Open the
cover before jump starting the
vehicle.
The negative battery terminal is stud
on a bracket located near the charger
modules.
Jump starting the vehicle
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of
your vehicle.
3. Connect the black lead to the negative terminal of the booster
vehicle battery.
4. Connect the other end of the black
lead to the negative battery
terminal (stud).

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 V vehicle
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.
Wrap a cloth around the tip of a slot
screwdriver to prevent paint damage. Insert the screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards.
The towing eye is stowed with the vehicle tools 3 230.
Screw in the towing eye anticlockwise
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.

Vehicle care241Bird 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 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.
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 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.
