Driving notes

Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear, and
possibly to brake failure.
Aquaplaning:
Reduce your speed when you drive on
wet or slushy roads. If you do not, a
wedge of water can form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized by a partial or complete loss of
contact between the tires and the road
surface. The ultimate results are loss of
steering and braking control.
Driving through water:
Do not drive through water that is
deeper than 1 foot (30 cm). If you must
drive through water accumulations up
to that depth, drive only at walking
speed. Driving at a faster speed could
cause damage to the engine, the elec-
trical systems and the transmission.
Package tray:
Never use the rear window shelf to
store heavy or bulky objects. If you do
so, such objects could pose the risk of
injury to vehicle occupants during
braking or evasive maneuvers or in a
crash.
Clothes hooks:
When suspending clothing from the
hooks, be sure that they will not
obstruct the driver's vision. Do not hang
heavy objects on the hooks. If you do
so, such objects could pose the risk of
personal injury during braking or
evasive
maneuvers.<

Catalytic converter

The catalytic converter reduces harmful
exhaust emissions, and 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
oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
> Be sure to comply with the scheduled
maintenance requirements.
> Fill the fuel tank well before it is
empty.
> Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, 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 in which the
fuel is not burned, or burns incom-
pletely, 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 allow the engine to run with
any of the spark plug cables discon-
nected.
