New vehicle break-in driving – the first 1,000 miles (1,600 km)
8-1. New vehicle break-in
driving – the first 1,000 miles
(1,600 km)
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
. Do not race the engine. And do not
allow engine speed to exceed 4,000
rpm except in an emergency.
. Do not drive at one constant engine or
vehicle speed, either fast or slow.
. Avoid starting suddenly and rapid ac-
celeration, except in an emergency.
. Avoid hard braking, except in an emer-
gency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads are
replaced with new ones.

8-2. Fuel economy hints

The following suggestions will help to save
fuel.
. Select the proper gear position for the
speed and road conditions.
. Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long as
possible.
. Do not pump the accelerator and avoid
racing the engine.
. Avoid unnecessary engine idling.
. Keep the engine properly tuned.
. Keep the tires inflated to the correct
pressure shown on the tire inflation
pressure label, which is located under
the door latch on the driver's side. Low
pressure will increase tire wear and fuel
consumption.
. Use the air conditioner only when
necessary.
. Keep the front and rear wheels in
proper alignment.
. Avoid carrying unnecessary luggage or
cargo.
8-3. Engine exhaust gas (car-
bon monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from entering
the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked ve-
hicle for a lengthy time while the
engine is running. If that is un-
avoidable, then use the ventila-
tion fan to force fresh air into the
vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
