Brakes: do not rest your foot on

the brake pedal while driving.

Even light but consistent pressure on

the brake pedal can lead to high

temperatures, brake wear and possibly

even brake system failure.

Aquaplaning: when driving on wet or

slushy roads, reduce vehicle speed. If

you do not, a wedge of water may form

between the tires and the road surface.

This phenomenon is referred to as

aquaplaning, or hydroplaning, and can

lead to partial or complete loss of

contact between the tires and road

surface, vehicle control and braking

ability.

Driving through water: do not drive

through water on the road if it is deeper

than 1 foot (30 cm), and then only at

walking speed at the most. Otherwise,

the vehicle's engine, the electrical

systems and the transmission may be

damaged.<

The catalytic converter reduces harmful

pollutants in the exhaust emissions.

It is designed for use with unleaded fuel

only. Even minute quantities of lead

would be enough to permanently

damage both the catalytic converter

and the system's oxygen sensor.

To ensure efficient, trouble-free engine

operation and to avoid potential

damage:

> Be sure to comply with the required

scheduled maintenance work and

repair procedures.

> Fill the fuel tank well before it is

empty.

> Tow-start only when the engine is

cold, otherwise unburned, residual

fuel in the catalytic converter could

ignite and cause damage. It is better

to jump-start the vehicle with outside

assistance.

> Avoid other situations where the fuel

is not burned, or burns incompletely,

such as engaging the starter

frequently or for extended periods, or

repeated start attempts in which the

engine does not start (stopping and

restarting an engine which is running

properly does not present a problem).

Never let the engine run with any of

the spark plug cables disconnected.

Be sure to observe the instruc-

tions above to prevent unburned

fuel from reaching the catalytic

converter. Otherwise there is danger of

overheating and damage to the cata-

lytic converter.

High temperatures occur in any vehicle

equipped with a catalytic converter.

Heat shields are installed adjacent to

some sections of the exhaust system.

Never remove these shields; do not

apply undercoating to their surfaces.

When driving, standing at idle, and

parking the vehicle, take extra care to

avoid contact between the exhaust

system and flammable materials (grass,

hay, leaves, etc.). Such contact could

start a fire, resulting in personal injury

and property damage.<
