Heat Up Switch
The heat up switch is located on the lower side of the instrument
panel. This switch is used to speed up the heater's operation when
the engine is cold.
When the ECM received the heat up switch ``ON'' signal, the ECM
increases the engine idle speed to 1,100 - 1,200 rpm to warm up
engine quickly.
This system works when all conditions listed below are met.
Heat up switch ON
Engine coolant temperature Below 70ÉC (158ÉF)
Shift lever ``P'' or ``N''
Accelerator pedal Fully released
Vehicle speed Below 4 km/h (2 MPH)

Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel ¯ows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may mis®re causing damage to the catalyst.
Do not place the vehicle on ¯ammable material. Keep ¯ammable
material off the exhaust pipe and the three way catalyst.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
HEALTH PROTECTION PRECAUTIONS
+Avoid prolonged and repeated contact with oils, particularly
used engine oils.
+Wear protective clothing, including impervious gloves where
practicable.
+Do not put oily rags in pockets.
+Avoid contaminating clothes, particularly underpants, with oil.
+Heavily soiled clothing and oil-impregnated footwear should not
be worn. Overalls must be cleaned regularly.
+First Aid treatment should be obtained immediately for open
cuts and wounds.
+Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
+Wash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.
+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+Where there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addition
an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt check with the
appropriate local authority and/or manufacturer of the approved
appliance.
