Replacing battery in radio remote
control
Replace the battery as soon as the
range reduces.
Batteries do not belong in household

212Vehicle care● Do not apply the parking brake.
● Open the bonnet, close all doors and lock the vehicle.Up to four weeks
Plug in the charge cord.Four weeks to 12 months ● Discharge the high voltage battery until two or three bars
remain on the battery range
indicator (battery symbol) on the
instrument cluster.
● Do not plug in the charge cord
● Always store the vehicle in a place with temperatures between−10 °C and 30 °C.
● Vehicle storage at extreme temperatures may cause
damage to the high voltage
battery.
● Remove the black negative (−) cable from the 12-volt vehicle
battery and attach a trickle
charger to the vehicle battery
terminals or keep the 12-volt vehicle battery cables connected
and trickle charge from thepositive (+) and negative (−)
terminals in the engine
compartment.Caution
The vehicle is equipped with an
AGM 12-volt battery, which can be damaged by using the incorrect
type of trickle charger.
An AGM compatible charger must be used, with the appropriate
setting selected.
Follow the trickle charger
manufacturer instructions.
After the vehicle battery cable is
reconnected, it is possible that the
vehicle may not operate. If this
happens, the high voltage battery
may need to be charged.
Putting back into operation
When the vehicle is to be put back into
operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Activate the electronics
of the power windows.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the coolant level.
● Fit the number plate if necessary.

216Vehicle care
Check to see if coolant is visible in thepower electronics and charger
modules coolant reservoir. If coolant
is visible but the coolant level is below
the cold fill line, there could be a leak
in the cooling system.
If the coolant level is too low, seek the assistance of a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
When adding windscreen washer
fluid to the vehicle, be sure to read the
manufacturer's instructions before
use.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
● When using concentrated washer fluid, follow the
manufacturer's instructions for
adding water.
● Do not mix water with ready-to- use washer fluid. Water can
cause the solution to freeze and
damage the washer fluid tank
and other parts of the washer
system.
● Fill the washer fluid tank only three quarters full when it is verycold. This allows for fluid
expansion if freezing occurs,
which could damage the tank if it
is completely full.
● Do not use engine coolant (antifreeze) in the windscreen
washer. It can damage the
windscreen washer system and
paint.

244Service and maintenanceThe international service intervals are
valid for the countries which are not
listed in the European service
intervals.
Confirmations Confirmation of service is recorded inthe Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.Recommended fluids,
lubricants and parts
Recommended fluids andlubricants
Only use products that have been
tested and approved. Damage
resulting from the use of non-
approved materials will not be
covered by the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop. The system is factory filled with coolant
designed for excellent corrosion
protection and frost protection down
to approx. -28 °C. In northern
countries with very low temperatures
the factory filled coolant provides frost
protection down to approx. -37 °C.
This concentration should be
maintained all year round. The use of additional coolant additives that
intend to give additional corrosion
protection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of
wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
