Complete protection-33°F
Vehicle may be driven away immediately from cold - 36°C

Lower protection-47°C
Prevents frost damage to cylinder head, block and radiator. Thaw out before
starting engine-53°F
CAUTION: Anti-freeze content must never be allowed to fall below 25% otherwise damage to the
engine is liable to occur. Also, anti-freeze content should not exceed 60% as this will greatly
reduce the cooling effect of the coolant.
FUEL REQUIREMENTS
Catalyst vehicles
Vehicles equipped with catalytic converter are designed to use ONLY unleaded fuel. Unleaded fuel must be used
for the emission control system to operate properly. Its use will also reduce spark plug fouling, exhaust system
corrosion and engine oil deterioration.
Using fuel that contains lead will result in damage to the emission control system and could result in loss of
warranty coverage. The effectiveness of the catalysts in the catalytic converters will be seriously impaired if leaded
fuel is used. The vehicle is equipped with an electronic fuel injection system, which includes two oxygen sensors.
Leaded fuel will damage the sensors, and will deteriorate the emission control system.
Regulations require that pumps delivering unleaded fuel be labelledUNLEADED.Only these pumps have nozzles
which fit the filler neck of the vehicle fuel tank.

REMOVE WHEELS, CHECK TYRES
Check tyres (including spare) for compliance with
manufacturers' specification.
Check visually for cuts, lumps, bulges, uneven tread
wear and tread depth. Check road wheels for
damage.
Check/adjust tyre pressures.
CHECK/TIGHTEN TOWING BRACKET FITTINGSINSPECT BRAKE PADS FOR WEAR, CALIPERS

Check thickness of brake pads, fit new pads if
minimum thickness is less than 3,0mm. Check brake
pads for oil contamination. If new brake pads required.
See BRAKES, Repair, Front Brake Pads
or.See 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.
Refit road wheels
Fit road wheels in original hub position. Secure in
position with wheel nuts, do not fully tighten wheel
nuts at this stage, lower vehicle and finally tighten
wheel nuts to correct torque.
