WASHING YOUR VEHICLE
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
During winter months, it is especially important to wash the
vehicle on a regular basis. Large quantities of dirt and road salt
are difficult to remove and also cause damage to the vehicle.
Any gasoline spilled on the vehicle or deposits such as bird
droppings should be washed and sponged off as soon as possible.
Deposits not removed promptly can cause damage to the vehicle’s
paintwork.
Remove any exterior accessories, such as antennas, before
entering a car wash. If you have wax applied to the vehicle at a
commercial car wash, it is recommended that you clean the wiper
blades and windshield as described inCleaning the wiper blades,
windshield and rear window.
After washing, apply the brakes several times to dry them.
WAXING YOUR VEHICLE
Waxing your vehicle on a regular basis will reduce minor scratches and
paint damage.
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Use a cleaning fluid with a
clean cloth to remove any bugs before waxing your vehicle. Use tar
remover to remove any tar spots.
Avoid getting wax on the windshield, or on any surfaces which
appear coarse or bumpy. If you have wax applied at a commercial
car wash, it is recommended that you clean the wiper blades and
windshield as described in Cleaning the wiper blades, windshield
and rear window.
Cleaning

While operating your vehicle
•Note any changes in the sound of the exhaust or any smell or exhaust
fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice any increased
steering effort or looseness in the steering wheel, or change in the
straight ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on a smooth, level road.
• When stopping, listen and check for strange sounds, pulling to one
side, increased brake pedal travel or “hard to push” brake pedal.
• If any slipping or changes in the operation of your transmission occur,
check the transmission fluid level.
• Check automatic transmission Park function.
• Check parking brake.
At least monthly
• Check function of all interior and exterior lights.
• Check tires for wear and proper air pressure.
• Check engine oil level.
• Check coolant level in the coolant reservoir.
• Check washer fluid level.
At least twice a year (for example, every spring and fall)
• Check power steering fluid level.
• Check clutch fluid level (if equipped).
• Check and clean body and door drain holes.
• Check and lubricate all hinges, latches, and outside locks.
• Check and lubricate door rubber weather strips.
• Check parking brake for proper operation.
• Check lap/shoulder belts and seat latches for wear and function.
• Check air pressure in spare tire.
• Check windshield washer spray and wiper operation. Clean wiper
blades with clean cloth dampened with washer fluid.
• Check safety warning lamps (brake, ABS, air bag, safety belt) for
operation.
Maintenance and Specifications
189

•Check cooling system fluid level and coolant strength.
• Check battery water level (non-maintenance free).
• Check battery connections and clean if necessary.
SERVICE RECOMMENDATIONS
To help you service your vehicle:
• We highlight do-it-yourself items in the engine compartment for easy
location.
• We provide a Scheduled Maintenance section which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your “Warranty Information” to find
out which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Genuine Mazda parts are designed and built
to provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
• Do not work on a hot engine.
• Make sure that nothing gets caught in moving parts.
• Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
• Keep all open flames and other lit material away from the battery and
all fuel related parts.
Working with the engine off
• Automatic transmission:
1. Set the parking brake and shift to P (Park).
2. Turn off the engine and remove the key.
3. Block the wheels.
• Manual transmission:
1. Set the parking brake, depress the clutch and place the gearshift in 1 (First).
2. Turn off the engine and remove the key.
3. Block the wheels.
Maintenance and Specifications
190

•Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster may reduce fuel economy.
• You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
• Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
• Resting your foot on the brake pedal while driving may reduce fuel
economy.
• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
• Use recommended engine oil. Refer to Lubricant specificationsin
this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle service maintenance section.
Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
• Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
• Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
• Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
• Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
