Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:
• Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare
from other driver's headlamps.
• Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it much
more difficult to see at night.
• Avoid staring directly at the
headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:
• Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.
• Turn OFF your Cruise Control.
• Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.
• Tires should be properly maintained
with at least 2/32nds of an inch of
tread depth. If your tires do not have
enough tread, making a quick stop on
wet pavement can cause a skid and
possibly lead to an accident. See "Tire
Tread" in chapter 8.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to "Tire Tread" in chapter 8.

Maintenance

While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling on smooth, level road.
• When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P
(Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year: (i.e., every
Spring and Autumn)
• Check radiator, heater and air
conditioning hoses for leaks or
damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields
and clamps.
• Check the seat belts for wear and
function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood
hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate automatic
transmission linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

Blade Inspection
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
arms or other components, do not:
• Use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
• Attempt to move the wipers
• manually.
• Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
CAUTION
Do not allow the wiper arm to fall
against the windshield, since it may
chip or crack the windshield.
ODN8089013
1. Within 20 seconds of turning off the
engine, lift up and hold the wiper
lever to the MIST position for about 2
seconds until the wipers move to the
top wipe position.
Information
This vehicle has a “hidden” wiper design
which means that the wipers cannot be
lifted manually when they are in their
bottom resting position.

2. At this time you can lift the wipers off
the windshield.
