properly, contact your Lexus dealer.

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.

211 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 COMPº switch until the zone number appears on the
display. Then push the COMPº switch, referring to the
following map to select the number of the zone where the
vehicle is.
16PY145

Zone numbers
Leaving the system after the calibration for several seconds,
the direction will appear on the display. It shows the zone
number is set.

CAUTION
Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.
Calibrating the compass (circling calibration)
To rectify the compass, stop the vehicle and push and hold the
COMPº switch until Cº appears on the display.
There is also a case that Cº appears on the display in case of
the drastic change of the magnetic field.
Drive the vehicle slowly (at 8 km/h [5 mph] or lower) in a circle
until the direction is displayed. If there is not enough space to
drive in a circle, drive around the block until the direction is
displayed.
After driving in 1 to 3 circles in the above method, calibration
is complete with the direction shown on the display.

STEERING WHEEL AND MIRRORS
213 Perform circling calibration just after you have purchased
your Lexus. And then always perform circling calibration
after the battery has been removed, replaced or
disconnected.
Do not perform circling calibration of the compass 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.).
During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.
CAUTION
When doing the circling calibration, be sure to secure
a wide space, and watch out for people and vehicles
in the neighborhood. Do not violate any local traffic
rules while performing circling calibration.
Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.

STARTING AND DRIVING
361
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 ONº, and check the fuel
gauge to see that you have sufficient fuel.
IGNITION SWITCH WITH STEERING
LOCK
STARTº Ð Starter motor on. The key will return to the
ONº position when released.
For starting tips, see page 363.
It is not a malfunction even if the needle of the tachometer, fuel
gauge or engine coolant temperature gauge returns to the
bottom position when the ignition switch is turned to the
STARTº position.
ONº Ð Engine on and all accessories on.
This is the normal driving position.
It is not malfunction even if the needle on the speedometer may
move when the ignition switch is turned to the ONº position.

(d) Backing up

1Brake pedal2Rº (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 Rº position.
NOTICE
Never shift into reverse while the vehicle is moving.
When the shift lever is shifted into Rº position, the outside rear
view mirrors automatically down to help backing up. For
details, see page 205.

DRIVING TIPS
427 7. Move the vehicle forward in the LOº (low) mode where the
hitch does not touch anything in the Nº (normal) mode.
8. Put the rear height control air suspension in the Nº (normal)
mode.
Pre-towing 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
vehicle-trailer 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 wheel 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.
