ANTI-FREEZE
PERCENTAGE CONCENTRATION - 50%
PROTECTION - LOWER TEMPERATURE LIMIT
Complete protection
Vehicle may be driven away immediately from cold,
-33°C (-36°F).
Safe limit protection
Coolant in semi-frozen state. Engine may be started
and driven away after warm-up period, -41°C (-42°
F).Lower protection
Prevents frost damage to cylinder head, block and
radiator. Thaw out before starting engine, -47°C (-53°
F).
CAUTION: Anti-freeze content must never
be allowed to fall below 25% (pre 99MY) or
50% (99MY on) otherwise damage to the
engine is liable to occur. Anti-freeze content
should not exceed 60% (all models) as this will
greatly reduce cooling efficiency.

MAINTENANCE SERVICE SCHEDULE
The following section describes the items detailed in
the vehicle Service Schedule. Where required
instructions are given for carrying out the service
procedure, or a cross reference is given to the section
in the manual where the procedure may be found.
Service Maintenance Schedules are published
separately to reflect the needs and intervals for each
vehicle variant. Procedures in the Workshop Manual
must be used in conjunction with the Service
Schedule sheets.
Service Maintenance Schedules are available from:

VEHICLE INTERIOR
CHECK SEATS & BELTS
Check condition and security of seat belts, seat belt
mountings, seat belt buckles and operation of inertia
seat belts.
CHECK OPERATION OF LAMPS
Check operation of all lamps, horns and warning
indicators.
CHECK OPERATION OF WIPERS
Check operation of front/rear wipers and washers and
condition of wiper blades.CHECK OPERATION OF HANDBRAKE
Handbrake check/adjust
1.Chock road wheels.
2.Raise one rear wheel clear of ground and
support securely with axle stand.
3.Release handbrake lever.
4.Underneath vehicle, tighten adjuster bolt
clockwise to
25 Nm (18 lbf/ft)to fully lock brake
drum.
5.Slacken adjusting bolt by 1.5 turns to give brake
shoes running clearance. Check that the drum is
free to rotate.
6.Adjust handbrake cable locknuts to give pawl
two notches free movement on the rachet before
being fully operational on third notch of rachet.
NOTE: Cable adjustment must ONLY be
used for initial setting and to compensate
for cable stretch. It MUST NOT be used to
take up brake shoe wear, which MUST be adjusted
at brake drum.

MAINTENANCE BATTERY CONNECTIONS
NOTE: The vehicle may be fitted with an
alarm and immobilisation system using a
battery backed-up alarm sounder.
See
ELECTRICAL, Repair, Battery
Disconnect battery leads, clean and grease with
petroleum jelly, including battery terminals.
CHECK OPERATION OF DOOR SWITCHES
When a Vehicle Immobilisation and Alarm System is
fitted it is important that all door and bonnet switches
operate correctly, otherwise perimeter and interior
protection may not function if a door or the bonnet is
opened.VEHICLE EXTERIOR
CHECK/ADJUST HEADLAMP ALIGNMENT
Check/adjust headlamp alignment.
CHECK ROAD WHEELS AND TYRES
Check road wheels for damage.
Check tyres, including spare, for compliance with
manufacture's specificaton.
Check visually for cuts, lumps, bulges, uneven tread
wear and tread depth.
See INTRODUCTION,
Information, wheels and tyres
Check/adjust tyre pressures.See WHEELS AND
TYRES, Repair, Tyres pressures
INSPECT BRAKE PADS FOR WEAR, CALIPERS
FOR LEAKS AND CONDITION OF DISCS
Check thickness of brake pads, and renew if thickness
is less than 3,00 mm (0.12 in). Check brake pads for
oil contamination and fit a new set, if necessary,
See
BRAKES, Repair, front brake pads
orSee
BRAKES, Repair, rear brake pads
WARNING: When renewing brake pads, it
is essential that only genuine components
with correct grade of lining are used.
Always fit new pads as complete axle sets, NEVER
individually or as a single wheel set. Serious
consequences could result from out of balance
braking due to mixing of linings.
CHECK FRONT WHEEL ALIGNMENT
Use recognised wheel alignment equipment to carry
out this operation.
See STEERING, Adjustment,
front wheel alignment

clearance of No.1 valve.
3.Slacken locknut and turn adjusting screw
clockwise to reduce clearance and
anti-clockwise to increase clearance. Tighten
locknut to
16 Nm.
