Driving and Operating 141
Never Stop the Engine While
Driving
{Warning
Do not move the engine control
switch away from the "ON"
position while the vehicle is being
driven.
If the engine stops while the
vehicle is moving, the brake
booster does not work, and the
brakes would not work properly.
The engine could also be
damaged.
Stopping the engine while driving
would be extremely dangerous
because the power steering
would stop working, making the
steering wheel extremely hard
to turn.
Stopping the engine while driving
would be extremely dangerous
because the warning lights,(Continued)
Warning (Continued)
indicator lights and other
electrical circuitry would
completely stop working.
Placing the engine control switch
in the "LOCK" position while
driving would be extremely
dangerous because the key could
come out, causing the steering
wheel to lock so that you could
not turn it.
You and others could be seriously
injured.
Avoid Unnecessary Idling of
the Engine
If the engine idles too long, the
engine coolant temperature will fall
below the operating range. Low
engine operating temperature
causes several conditions that are
harmful to engine operation and life.
Incomplete combustion of fuel in an
engine that is not fully warmed-up
causes crankcase dilution and
forms lacquer and gummy deposits on valves, pistons, and rings. It also
causes rapid accumulation of
sludge within the engine.
Driving at Night
Nighttime driving is more dangerous
than daytime driving because the
field of view is narrower. Keep your
speed down, and maintain an ample
headway distance.
Metallic Plinking Sound from
the Muffler
Immediately after stopping the
engine, you may hear a metallic
plinking sound from the muffler. This
sound occurs as the muffler cools
down and contracts. It does not
indicate an abnormality or
breakdown.

Driving and Operating 147
Parking, or Leaving
Driver’s Seat
{Danger
It can be dangerous to get out of
your vehicle if the selector lever is
not fully in "P" (Park) or the
parking brake is not applied all
the way. Your vehicle can roll or
move suddenly.
To be sure your vehicle will not
move, even when you are parking
on level ground, follow the steps
below. (If you have to park on a
hill, also turn your front wheels so
the vehicle will roll away from
traffic.)
You and others could be seriously
injured or killed.
1. Hold the regular brake pedal down with your right foot and
apply the parking brake all the
way before shifting the
transmission. Follow the
Parking Brake instructions in
this manual for your vehicle. 2. To move the selector lever to
"P" (Park), hold in the button
on the lever and push the lever
all the way toward the front of
your vehicle.
3. Turn the key to "LOCK".
4. Remove the key and take it with you.
5. Before you leave the driver's seat, be sure the vehicle is not
moving, or check that your
vehicle is in Park by trying to
pull the selector lever out of "P"
(Park) by pulling the selector
lever toward you without
pushing the button. If you can
do this, it means that the
selector lever was not fully
locked into "P" (Park).
Do Not Touch the Selector Lever
While the Vehicle is Stationary
with the Engine Idling
Do not touch the selector lever while
the vehicle is stationary with the
engine idling. If you touch the
selector lever at this time, a gear
could be selected and the vehicle
could move even with the parking brake applied. The risk of knocking
against the selector lever and
causing a crash is particularly great
when you move in or out of
your seat.Driving Down a Long Slope
When driving down a long slope,
use the exhaust brake together with
the foot brake. Using the exhaust
brake and low-gears reduces the
work load on the foot brakes and
yields greater braking force. Even
so, use the foot brakes
appropriately to prevent the engine
over-revving.
Frequent use of the foot brakes can
cause vapor lock and brake fade,
resulting in reduced brake
effectiveness.
Brake Fade :
Frequent use of the
brakes can cause the brakes to
overheat so that the frictional force
of the brake linings decreases and
the brakes become less effective
than normal. This phenomenon is
called brake fade.

Driving and Operating 151
.When going down on a steep
slope, avoid driving the vehicle
backward as much as possible.
Drive it forward slowly on the
down slope.
. Compared with forward
movement, the braking distance
of backward movement is longer,
and the steering response of
that is worse.
. If you must drive the vehicle
backward, drive it very carefully
and gradually by moving and
stopping repeatedly in order to
stop it any time.
Engine Brake : Engine brake is the
braking effect that occurs when you
release the accelerator pedal while
driving. The lower the gear, the
stronger the engine brake.
Exhaust Brake : The exhaust brake
is a system that closes the exhaust
pipe and uses the force of the
exhaust emissions to enhance the
effectiveness of engine brake. Overrunning :
An engine overrun is
an engine-speed increase that
causes the tachometer needle to
enter the red zone. It is dangerous
because it can cause engine failure.
Winter Driving
Recommendations for Driving
in Cold Regions
The following recommendations
apply to snowbound regions and to
mountainous regions, ski resorts
and other areas of extreme cold
and/or snowfall. Please follow them
also for reference in winter in other
regions.
For the sake of your vehicle, make
the winter preparations described in
the links below. Also have these
preparations made before driving to
a cold region.
See Engine Oil 0245.
See Engine Coolant 0253.
See Washer Fluid 0262.
See Battery - North America 0269.
When Ice Prevents You from
Putting Your Key in the Door
or Opening the Door
If you try to force the key into the
door, you could bend it. And if you
try to pull the door open with undue
force, the rubber seal around the
door could come unstuck or become
damaged. Use warm water to melt
the ice, then quickly wipe it away
and open the door.
If the wipers, electric door mirrors,
or power windows freeze up, also
use warm water to melt the ice and
then operate the system. Otherwise,
you could damage the mechanism
and drain the battery. After that,
wipe the water away.
Before Driving in Cold Regions
Getting In and Out of the Vehicle
The step can get icy in cold regions.
Be careful not to slip when getting in
and out of the vehicle.

be burnished as part of the new
vehicle break-in procedure.
Increased parking brake
performance will result when the
parking brake is burnished as
specified below:
.Make 10 moderate stops, using
the hand brake, from 16 km/h
(10 MPH) while spacing the
stops a minimum of 4 km
(2.5 miles) apart.
. Operate the vehicle at 32 km/h
(20 MPH) between stops.Pedals
Sit in a correct driving position on
the seat and operate the brake
pedal (1) and accelerator pedal (2)
with your right foot. To avoid
accidentally pressing the wrong
pedal, check the pedal positions
and practice putting your foot on the
desired pedal.
