Congrats bro. What color is ur car and is it 1.6 or 2.0? Mind sharing with me how much discount do u get? Planning to get one myself.

Dear bro,
Seems you are so concerned with your fuel consumption,
you might as well try below listed suggestion. Cerato 1.6 and Elantra 1.6 use d same 1.6 gamma mpi engine with 6 gearbox right? D different is elantra gives 16inch rim and eco mode while Cerato is 17 inch rim without eco. I presume it is a no brainer for Kia to give eco mode coz Cerato need to pull d 17inch rim.

1) downgrade your rim to 16inch
2) keep Cerato spare tyre at home. Loose out the extra weight.
3) tinted your Cerato with the highest quality TSER% tinted film money can buy
4) make sure every week refill your tire pressure to the right amount. The best go to Petronas or alignment shop use nitrogen. Normal air 1 week average can loose 1 psi for 1 tyre. If nitrogen last longer.
5) minimize electrical activity in ur car. Charging i phone inside ur car is using your Ron 95 primax bear in mind. If u use korean phone or china xiaomi with 3000 mh battery should last a day without needing to use fuel to charge your phoneinside car.
6) drive your car using bare foot without shoes as lightly as you can when pressing the pedal. Be one with your car. Feel it. Love it. Take good care of it.
7) never install any other bullshit product that claim to save petrol. Interfering with your car electrical system will only damage it on the long run. If can really save fuel Kia surely fitted it in from factory already no need to supply at Brothers haha. Only Mazda with skyactive 14:1 compression ratio engine combine with i-eloop cN beat hybrid car fuel efficiency as per current technology that i know. Other  sciencetis in Lowyat will damage ur car only unfortunately.
ENJOY YOUR RIDE

just wondering, will it void any warranty if I were to install a new car horn? Don't really like the sound of the existing horn

The car is a good car, and buying car, sometimes it's down to luck. But when it boils down to that, it depends heavily on the vendor's ability to support the car.

I believe Naza Kia still has a lot to improve in terms of quality, QC and the after sales support. They seem to be able to sort out only basic problems, whilst more complicated problems, they are left in the dark.

Perhaps it's because this model is too new and needs more time to maturize.

Ya, monocle, I think so too.  What is the normal rpm when idle with air con turned on? Guess I have to go back to SC on Mon. It took me 5 and a half hour today at Setapak branch.

i experience this currently in my new cerato. what i notice is that the front speakers (driver, front passenger and both dashboard sides) will be override for the speednavi system to kick in. the annoying part is that it happens intermittently. for a while the radio comes on again, then off, then on again...
seems unusual to me...anybody else experiencing this? or you guys have no problem when operating gps+radio/dvd together?
