The compass may not show the correct direction in the
following conditions:
 The vehicle is stopped immediately after turning.
The compass does not adjust while the vehicle is stopped.
 The ignition switch is turned off immediately after turning.
 The vehicle is on an inclined surface.
 The vehicle is in a place where the earth’s magnetic field is
subject to interference by artificial magnetic fields
(underground parking, under a steel tower, between
buildings, roof parking, near a crossing, near a large vehicle,
etc.).
 The vehicle is magnetized. (There is a magnet or a metal
object on or near the inside rear view mirror.)
 The battery has been disconnected.
Your vehicle is out of the set zone. Refer to the “Calibrating the
compass” in this section to set the zone number.
The compass works to calibrate the direction automatically
while the vehicle is in motion, if deviation is small.

NOTICE
Do not put magnets or a metal object on or near the
inside rear view mirror of the vehicle. Doing this may
cause malfunction of the compass sensor in the mirror.
Calibrating the compass (deviation calibration)
The direction display on the compass deviates from the true
direction determined by the earth’s magnetic field. The angle
of deviation varies according to the geographic position of the
vehicle.
To adjust this deviation, stop the vehicle, then push and hold
the “COMP” switch until the zone number appears on the
display. Then push the “COMP” switch, referring to the
following map to select the number of the zone where the
vehicle is.

COMFORT ADJUSTMENT

When using the left side lower anchorages for the
child restraint system, do not sit in the center seat.
The performance of the center seat belt cannot be
brought out sufficiently because the belt may be
highpositioned or the seat belt may be loosefitting,
posing the risk of serious injury in the case of
collision.
DRIVING POSITION MEMORY
SYSTEM
A microcomputer will memorize the position of the driver’s
seat, and the positions of the tilt and telescopic steering, and
outside rear view mirrors. Two dif ferent driving position profiles
can be entered into the computer’s memory.
Recording the driving position in the computer’s memory can
only be done when the ignition key is in the “ON” position and
the selector lever is in the “P” position.
Setting the driving position
1. Adjust the driver’s seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the “SET” button, push button “1” or “2”
until the signal beeps.

STARTING AND DRIVING
299
To allow proper operation of your vehicle’s
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the back door closed. Have
the cause immediately located and corrected.BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint height
and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to “ON”, and check the fuel
gauge to see that you have sufficient fuel.

STARTING AND DRIVING
307
(c) Using the “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for strong engine\
braking
as described previously.
With the selector lever in “3”, “2” or “L”, you can start the vehicle
in motion as with the lever in “D”.
With the selector lever in “3” or “2”, the vehicle will start in firs\
t
gear and automatically shift to second gear.
With the selector lever in “L”, the transmission is engaged in
first gear.
NOTICE
 Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given below for your
reference:
Transmission Transfer
“L” “H”
“3” 53 km/h (33 mph) 136 km/h (85 mph)
“2” 36 km/h (22 mph) 93 km/h (58 mph)
“L” 21 km/h (13 mph) 54 km/h (33 mph)
 Do not continue hill climbing or hard towing for a long
time in the “3”, “2” or “L” position. This may cause
severe automatic transmission damage from
overheating. To prevent such damage, “4” position
should be used in hill climbing or hard towing.
(d) Backing up
 1 Brake pedal 2 “R” (Reverse) position
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the
selector lever to the “R” position.
NOTICE
Never shift into reverse while the vehicle is moving.
When the shift lever is shifted into “R” position, the outside rear
view mirrors automatically down to help backing up. For
details, see page 116.

DRIVING TIPS
354
Pretowing safety check
Check that your vehicle remains level when a loaded or
unloaded trailer is hitched. Do not drive if the vehicle has an
abnormal nose −up or nose− down condition, and check for
improper tongue load, overload, worn suspension or other
possible causes.
 Make sure the trailer cargo is securely loaded so that it
cannot shift.
 Check that your rear view mirrors conform to any federal,
state/provincial or local regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.
Trailer towing tips
When towing a trailer, your vehicle will handle differently
than when not towing. The three main causes of
vehicletrailer accidents are driver error, excessive speed
and improper trailer loading. Keep these in mind when
towing:
 Before starting out, check the operation of the lights and all
vehicle −trailer connections. After driving a short distance,
stop and recheck the lights and connections. Practice
turning, stopping and backing with a trailer in an area away
from traffic until you learn the feel. 
Backing with a trailer is difficult and requires practice. Grip
the bottom of the steering whe el and move your hand to the
left to move the trailer to the left. Move your hand to the right
to move the trailer to the right. (This procedure is generally
opposite to that when backing without a trailer.) Also, just
turn the steering wheel a little at a time, avoiding sharp or
prolonged turning. Have someone guide you when backing
to reduce the risk of an accident.
 Because stopping distance may be increased,
vehicle −to−vehicle distance should be increased when
towing a trailer. For each 16 km/h (10 mph) of speed, allow
at least one vehicle and trailer length between you and the
vehicle ahead. Avoid sudden braking as you may skid,
resulting in jackknifing and loss of control. This is especially
true on wet or slippery surfaces.
 Avoid jerky starts or sudden acceleration.
 Avoid jerky steering and sharp turns. The trailer could hit
your vehicle in a tight turn. Slow down before making a turn
to avoid the need of sudden braking.
 Remember that when making a turn, the trailer wheels will
be closer than the vehicle wheels to the inside of the turn.
Therefore, compensate for this by making a larger than
normal turning radius with your vehicle.

RAIN CLEARING MIRRORS
The rear view mirrors have been coated to produce a “rain
clearing” effect. This coating causes the raindrops to
spread, clearing the driver’s rear view when it rains.
It is sufficient to wash the mirrors with water for day to day care.
The rain clearing effect is reduced in drizzle and light rain.
In the following cases, the rain clearing effect will be reduced
temporarily, but will gradually recover.
After wiping dirt off the mirrors
 When the mirrors fog up
 After waxing your vehicle in an automatic car wash
 After your vehicle has been parked for a long period in
underground parking lots, etc. where there is no direct
sunlight.
If you would like to restore the rain clearing effect to its normal
level immediately in the above cases, wash the mirrors with
neutral detergent, then rinse thoroughly.
NOTICE
To maintain the rain clearing ability, and prevent the
mirrors from being scratched, observe the following
precautions.
 Do not use any glass cleaners that contain
compounds.
 If ice should jam the mirror, do not scrape the mirror.
Use a spray deicer to free the mirror.
 Wash off any wax stuck to the mirrors with neutral
detergent and rinse thoroughly as any wax on the
surface of the mirrors can cause the rain clearing
effect to be lost.
 Do not use any water repellents as they can destroy
the rain clearing effect. If any repellent gets stuck on
the surface of the mirrors, wash it off with neutral
detergent, then rinse thoroughly.
