Electrical System
Winter conditions impose severe demands
upon vehicle electrical systems, particularly
the charging circuit. The battery condition and
performance along with the alternator perfor-
mance and drive belt condition should be
checked prior to the onset of winter.
ZC170C1-E
Anti-freeze/Corrosion inhibitor
The cooling system must always contain an
Ethylene-Glycol based anti-freeze solution.
The system is filled during manufacture with
solution of the correct strength which should
be checked before the onset of winter and
adjusted or changed as required.
NOTE:
The anti-freeze solution contains a corro-
sion inhibitor to prevent degradation of the
aluminum castings contained within the
engine. Therefore, never, drain the system
and refill with water only.
In addition, anti-freeze solution must ALWAYS
be used in vehicles fitted with air conditioning,
to prevent the heater matrix from freezing and
subsequently bursting with the refrigeration
system in use.

Door Locks
Should the door lock mechanism become
frozen, a proprietary lock de-icer should be
used. Alternatively, warming the door key
may thaw the door lock. However, the key
should be handled carefully to avoid burning
the fingers.
Never attempt to thaw a frozen door lock
using hot water, since the water will eventu-
ally freeze and compound the problem.
NOTE:
The proper temperature for using the im-
mobilizer key is from -40°F to 176°F (-40°C
to 80°C). If you heat the immobilizer key
over 176°F (80°C) to open the frozen lock,
it may cause damage to the transponder
in its head.

Windscreen Washers and Wipers
The windscreen washer bottle should be filled
with a solution of water and a proprietary
winter screen wash additive. The windscreen
wipers should not be used if the blades are
frozen to the windscreen or if they are cov-
ered with snow, before this is removed.
NOTE:
Never allow undiluted screen washer fluid
additive to spill upon the paintwork or use
engine coolant anti-freeze since damage to
the paintwork may result.
o When driving in extreme conditions, the
windscreen wiper blades may fail to clear
the screen properly due to the formation of
ice upon the blade edge. It will therefore be
necessary to periodically remove such ice
to restore their efficiency.
o If the power operated door mirrors become
frozen, attempts to adjust these may dam-
age the mechanism.
o The formation of snow or ice built up inside
the wheel arches may interfere with the
road wheels or steering mechanism. In
such instances, unusual noises or an in-
crease in steering effort may result. There-
fore, ensure that the wheel arches are
checked periodically and any accumulated
snow or ice removed.
o It is advisable to carry emergency equip-
ment including, torch, shovel, tow rope,
blankets etc., if a journey is to be under-
taken into areas of severe road conditions.
