Maruti Suzuki's Daily Dont's
While doing the inspection-
Do not Touch or Open Radiator Cap when Engine is Hot.
Do not fit non-genuine accessories that may affect performance.
Do not use Non Genuine Spares. Use only Maruti's Genuine Parts.
Do not park in sun for too long. Park under shade.
Start vehicle periodically if parked /unused for long.
Fuel Efficiency
Better driving habits for fuel saving
Drive between 45-55 kmph
Drive slow and steady. The faster you go, the more the wind resistance your vehicle will face. It has been established by trials that you can get upto 40% extra mileage at 40 kmph as compared to 80 kmph.
Avoid accelerating or decelerating unnecessarily
Always drive in the correct gear
Incorrect gear shifting can lead to as much as 20% increase in fuel consumption.

Remember : For city driving, change to a higher gear when you are sure that the engine will not have to struggle.
Get into top gear as soon as possible. 
While braking anticipate stops
Stop-and-go driving wastes fuel. When you slam on the brakes, a lot of useful energy is wasted in the form of heat.
Proper synchronization of gear and accelerator is necessary for better mileage.

Remember : check wheels for free rotation when your car is being serviced. Binding brakes restrict free wheel movement and the engine consumes more petrol in order to overcome resistance.    

Keep your foot off the clutch
Use your clutch only when you change gears. Riding the clutch causes loss of energy and damages clutch lining.
Remember : Use your hand brakes when stopping on up gradient. Don't manipulate the clutch and accelerator to stay stationary because it wastes fuel.        
Periodic servicing
Servicing of your vehicle must be carried out as specified in User's manual. 
Use the recommended Spares & Lubricants
Always use recommended spares & Lubricants
Engine oil that is thicker than recommended can cause a 2% increase in fuel consumption

Remember : Check the car manual and the oil manufacturer's recommendations, before using any particular grade of oil.

Clean your air filter regularly
Your air filter prevents air from fouling the engine. Dust causes rapid wear of engine components and increases fuel consumption.

Remember : Cylinder bores and piston rings wear out faster in engines with dirty air cleaners.

Clean air filters at every tune up.
Do not allow leakage or spillage
Loss of one drop of petrol per second can amount to loss a of 2000 litres per year.
Make sure that the fuel tank cap has a good rubber seal.
Don't wait for your car to warm up
Instead drive in low gear till the engine warms up.
Do not use the choke longer than necessary.
Reduce loads
Unnecessary loads increase fuel consumption.
Do you really need to carry the luggage rack or various odd things in the boot all the time?

Remember : A reduction of weight by about 50 kg can lead to a 2% saving in fuel , when driving in city.  

Check your tyre pressure regularly
Under inflated tyres increase rolling resistance which leads to higher petrol consumption & faster wear out of tyres at sides .

Remember : A 25% decrease in tyre pressure can cost you 5 -10% more on petrol and 25% on tyre life.     

When you stop your car, stop your engine
Idling for an hour costs One litre of petrol Always keep your car ready for starting quickly. Keep the battery , alternator & fan-belt in good condition. This will ensure a good start whenever you need it.

Remember : Switch off the engine at stops of over 2 minutes.           

Plan your route
Fuel consumption on a highly congested road can be double the normal.
Rush hour or stop-and-go traffic can waste fuel excessively.

Remember : You will get more mileage from each litre if you take a less congested route.   

FAQ
When should the air filter be replaced?
Road Condition

Variant

Preventive Maintenance

Paved-road

Petrol

Clean after every 5,000 KM and replace after every 40,000 KM.

Diesel

Replace after every 20,000 KM as cleaning is not required.

Dusty

Petrol

Clean after every 2,500 KM or as required and replace after every 40,000 KM.

Diesel

Replace after every 20,000 KM. Cleaning not required. More frequent replacement if dust condition is severe.

In what frequency should the fuel filter be changed?
The fuel filter should be changed at intervals of 20000 kms for carburettor vehicles. In case of MPFI vehicles, the interval is 40000 kms. However, if quality of fuel has been poor, it is recommended that you change the filter at earlier intervals as prescribed by the service manager of the Maruti authorised workshop.
How important is preventive maintenance? Where can I get it done?
In your owner's manual, you will find "Periodic Maintenance Schedule" under the "Inspection and maintenance" section. This will guide you on how often you must send you car to the Maruti authorized workshop for check up and maintenance service. Doing so will not only prolong the life of your vehicle but will also reduce maintenance costs. The car will be trouble free and completely safe for use. We urge you to carry out your car maintenance services only with Maruti authorized workshops.
Do I need to strictly follow the schedule in the owner's handbook?
Yes, it is imperative that you follow the regular periodic maintenance schedule as listed in the owner's manual. This will ensure trouble free operation of the vehicle and enhance the life of the engine. Also, this is a pre requisite for any warranty claims to be processed, should any part fail within the warranty period.     
How do I know if gas is less than normal in the AC system?
If cooling efficiency of AC is less than satisfactory, do check for gas leakage. There are various methods to check whether the quantity of gas is adequate. However, it is best that you rely on the AC maintenance experts at Maruti authorised service stations to do the checking. They will have the right instruments and expertise to assess if gas in the AC system of your vehicle is below norms. Get your car AC serviced every year and do it around Feb - March so that you may enjoy best cooling during summer. Gas checking and topping is part of the service.          
In the AC system, what are the functions of coil, condenser, and blower?
The cooling coil performs the function of evaporation of the refrigerant inside the coil. The air blows over these coils and emerges cooled.
The condenser does the reverse work of the cooling unit, i.e. the condensation of the refrigerant and its cooling.
The blower works like a fan by drawing in the air and circulating it inside the cabin.           
Which parts /joints are the main sources of gas leakage?
The AC gas in cars reduces over time due to various factors like-
Leakage from the joints, o-rings etc., if they were not properly tightened during service.
Leakage from the hose rubber, due to the natural permeability of the hose. However,
this is extremely slow and is very difficult to detect, even with sophisticated equipment.
The AC gas may need to be refilled during servicing of the AC, if it is found that the AC system is undercharged.
How would I know if there is a leak in the battery?
There is a different rusting pattern for a battery electrolyte spill and a different rusting pattern for a water spill. It will take an expert to gauge the kind of leak and spot the reasons for it. Hence we advise you to kindly contact the nearest Maruti Authorized Dealer or Service Station and follow their advice.
