NOTE
To meet government regulations and pro- mote cleaner air, your vehicle is equipped with an onboard diagnostic system (OBD). The engine electronic control module that controls OBD functions stores various data(especially about the exhaust emissions). This data will be erased if the battery cable is disconnected, which could make a rapiddiagnosis difficult. Do not disconnect the battery cable when the engine malfunction indicator (“SERVICE ENGINE SOON” or“Check engine light”) is ON.
Spark plugs
NOTE
Use the spark plugs listed under “Engine specifications” on page 11-4 or plugs that are exactly the same. Other plugs could causeengine damage, performance problems or radio noise.

To protect your vehicle’s finish, wash it often and thoroughly. If desired, you may wax yourvehicle using a nonabrasive automobile wax.
N00945800033
Industrial pollution, road tar, bird droppings,tree sap, insect remains, sea water and otherforeign matters can damage the finish on your vehicle. Generally, the longer any foreign materialstays on the finish, the worse the damage. Wash your vehicle as soon as possible when- ever the finish gets soiled.

Chemicals contained in the dirt and dustpicked up from air, rain, snow, or road sur-faces can damage the paint and body of your vehicle if left on. Frequent washing and waxing is the best wayto protect your vehicle from this damage. Do not wash the vehicle in direct sunlight. Park the vehicle in the shade and spray it withwater to remove dust. Next, using plenty of
clean water and a car washing mitt or sponge, wash the vehicle from top to bottom. Use a mild car washing soap if necessary. Rinse thoroughly and wipe dry with a cham-ois or soft cloth. After washing the vehicle, carefully clean the joints and flanges of the doors, hood, etc., where dirt is likely toremain.
Salt and other chemicals spread on winter roads in some geographical areas can have a detrimental effect on the vehicle underbody.

CAUTION When washing the underside of your vehicle or the wheels, wear a pair of gloves to pro- tect your hands. If your vehicle has rain sensor wipers, place the wiper switch lever in the “OFF” positionto deactivate the rain sensor before washing the vehicle. Otherwise, the wipers will oper- ate in the presence of water spray on thewindshield and may get damaged as a result. Never spray or splash water on the electrical parts in the engine compartment. This may damage them. Be careful also when washing the underbody to ensure that water does notenter the engine compartment. Avoid automatic car washers that use rotat- ing brushes. These brushes may scratch the paint surface and make it dull. Scratches are more noticeable on darker col- ored vehicles.
Some hot water washing equipment uses high pressure and heat to clean your vehicle. Because hot water can damage plastics parts and seep inside your vehicle, make sure you do the following when using such equip-ment:• Keep the washing nozzle at least 28 inches(70 cm) away from the vehicle body.• When washing around the door glass, holdthe nozzle at a distance of more than 28 inches (70 cm) and at a right angle to the glass surface.
Make sure to do the following when using an automatic car wash, with help from eitherthis manual or the car wash operator, to avoid damaging your vehicle:• Fold the outside rearview mirrors.• Remove the antenna.• Tape the wiper arm assembly.• If your vehicle is equipped with a rearspoiler or roof rails, check with the car wash operator before using the car wash.• If your vehicle is equipped with the rainsensor wipers, place the wiper switch leverin the “OFF” position to deactivate the rain sensor.

You should flush the underbody with a high pressure hose every time you wash the out- side of your vehicle. Take special care to remove mud or otherdebris which could trap and hold salt and moisture. After washing your vehicle, wipe off allwaterdrops from the rubber parts around the doors to prevent the doors from freezing.

Wax your vehicle once or twice a year, or when water does not bead up on the paint.Use a soft cloth to put a small amount of wax on the painted surfaces. After the wax has dried, polish with a dry soft cloth.Do not wax your vehicle in direct sunlight. You should wax when the painted surfaces are cool.
N00946100046
If painted surfaces have been severely dam-aged and lost their original luster and color tone, polish the surface lightly with a fine polishing compound. Avoid limiting yourpolishing to the damaged surface only; polish a somewhat wider area, moving the polishing cloth in one direction. After polishing, flushthe compound from the surface and apply a coat of wax to regain a beautiful luster.
N00946200047
Small cracks and scratches in the paint coat should be touched up as soon as possible withtouch-up paint to prevent corrosion. Check body areas facing the road or the tires carefully for damage to the paint caused byflying stones, etc. The paint code number for your vehicle can be found on the vehicle information code plate in the engine compart-ment.

Use a sponge or chamois to clean these parts.If a vehicle wax sticks to a gray or blackrough surface of the bumper, molding or lights, the surface may appear white in color. In this case, wipe it
off using lukewarm water
and a soft cloth or chamois.
NOTE
When the door is frozen, opening it by force may tear off or crack the rubber gasket installed around the door. Pour warm water to melt the ice. Be sure to thoroughly wipeoff the water after opening the door. To pre- vent freezing of the weatherstripping on the doors, hood, etc., treat
with silicone lubri-
cant.
Waxing
CAUTION Waxes containing high abrasive compounds should not be used. These waxes remove rust and stain effectively from the paintwork, but are harmful to the finish of the paint, because they also remove paint/clearcoat.They are also harmful to other glossy sur- faces such as the grill
e, trim, moldings, etc.
Do not use gasoline, benzine, kerosene or paint thinners to remove road tar or other dirt from the vehicle surface. Do not put wax on the areas having black matte coating because it can cause unevendiscoloration, patches, blurs, etc. If these get wax on them, wipe the wax off right away with a soft cloth and warm water.
Polishing
Damaged paint Cleaning plastic parts
CAUTION Do not use a scrubbing brush or other rough scrubber as these may damage the plastic surface. Do not use wax containing compounds (pol- ishing powder) which may damage the plas-tic surface.
