Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make “kangaroo” starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption.
Keep your car in good condition. For better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see Section
7 for details). Keep your car clean. For maximum
service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
Remember, your vehicle does not require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't “labour” or “over-rev” the engine. Labouring is driving too slowly in toohigh a gear resulting in the engine
bucking. If this happens, shift to a lower
gear. Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.
ECONOMICAL OPERATION

533
Driving your vehicle
Use your air conditioning sparingly.The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorised
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.

When you are ready to leave after park- ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down while you:

and

2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks. E140500AUN-EA
Maintenance when trailer towing
Your vehicle will need service more often
when you regularly towing a trailer.
Important items to pay particular atten-tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to check frequently. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re towing, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nutsand bolts should be tight.
WARNING
- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others can be seriously injured
or cause fatality.CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicates
over-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan to improve engine performance
when towing a trailer.
