Maintenance
Waxing
A good coat of wax provides a barri-
er between your paint and environ-
mental contamination. Keeping a
good coat of wax on your vehicle willhelp protect it.
Wax the vehicle when water will no longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-ing.
OLMB073082
Water washing in the engine
compartment including high
pressure water washing maycause the failure of electrical
circuits located in the engine
compartment.
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
CAUTION
Do not use strong soap,
chemical detergents or hot
water, and do not wash the
vehicle in direct sunlight or
when the body of the vehicleis warm.
Be careful when washing the
side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the inte-
rior.
To prevent damage to the
plastic parts, do not clean
with chemical solvents or
strong detergents.
To prevent damage to the
charging door, make sure to
close and lock the vehicle
doors when washing (high-
pressure washing, automatic
car washing, etc.) the vehicle.
CAUTION

Recommended SAE viscosity
number
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
CAUTION
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy and cold weather performance,
however, higher viscosity engine oils are required for satisfactory lubrication
in hot weather. Using oils of any viscosity other than those recommended
could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.
Temperature Range for SAE Viscosity Numbers
Temperature -30 -20 -10 0 10 20 30 40 50
-10 0 20 40 60 80 100 120
Engine Oil *110W-30
5W-20, 5W-30
°C
(°F)
* 1
For better fuel economy, it is recommended to use the engine oil
of a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However,
if the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
