NOTICE
Do not drive the vehicle with the engine oil pressure
below the normal range until the cause is fixed it may
ruin the engine.
VOLTMETER
13X503a
 1 Normal range 2Charging system warning light
The voltmeter tells whether the battery is charged or
discharged. Check it while the engine is running the
needle should always indicate as shown above.
If the needle reads below or above the normal range while the
engine is running, it indicates the charging system needs
immediate repair.
However, it is normal for the needle to drop below the normal
range during engine starting.

(n) Lexus Night View System Warning Light
When this light comes on, the bulb for the near−infrared
floodlight (night view projector) is burned out. Have it replaced
at Lexus dealer.
(o) Charging System Warning Light
This warning light comes on when the ignition switch is turned
to the “ON” position, and goes off when the engine is started.
When there are problems in the charging system while the
engine is running, the warning light comes on.
NOTICE
When the charging system warning light comes on
while the engine is running, malfunctions such as the
engine drive belt being broken may have occurred. If
the warning light comes on, immediately stop the
vehicle in a safe place and contact your Lexus dealer.
(p) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.
(q) Low Washer Fluid Warning Light
This light comes on when the fluid level in the tank becomes
very low. Fill the tank as soon as possible.
(r) Key Reminder Buzzer
This buzzer acts as a reminder to remove the key when you
open the driver’s door with the ignition key in the “ACC” or
“LOCK” position.

STARTING AND DRIVING
265
(e) Parking
31X011d
 1Brake pedal 2Parking brake lever
3“P” (Park) position
1. Bring the vehicle to a complete stop.
2. Apply the parking brake fully.
3. With the brake pedal held down with your foot, shift the
selector lever to the “P” position.
CAUTION
While the vehicle is moving, never attempt to move the
selector lever into “P” under any circumstances.
Serious mechanical damage and loss of vehicle control
may result.
(f) Good driving practice
 If the transmission repeatedly shifts up and down between
the fourth and overdrive gears when climbing a gentle
slope, shift the selector lever to the “4” position. Be sure to
shift the selector lever to the “D” position after climbing the
slope.
 When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or parking brake to hold the
vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.

DRIVING TIPS
325
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 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.
 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.
 Crosswinds and rough roads will adversely affect handling
of your vehicle and trailer, causing sway. Pay attention to
the rear from time to time to prepare yourself for being
passed by large trucks or buses, which may cause your
vehicle and trailer to sway. If swaying happens, firmly grip
the steering wheel and reduce speed immediately but
gradually. Never increase speed. If it is necessary to
reduce speed, brake slowly. Steer straight ahead. If you
make no extreme correction with the steering or brakes,
your vehicle and trailer will stabilize.
 Be careful when passing other vehicles. Passing requires
considerable distance. After passing a vehicle, do not
forget the length of your trailer and be sure you have plenty
of room before changing lanes.
 In order to maintain efficient engine braking and electrical
charging performance, do not use overdrive. T ransmission
must be “4” position.

IN CASE OF AN EMERGENCY
337
When boosting, use the battery of matching or higher quality.
Any other battery may be difficult to jump start with.
If jump starting is difficult, charge the battery for several
minutes.
2. If required, remove all the vent plugs from the booster
battery. Lay a cloth over
the open vents on the booster battery.
(This helps reduce the explosion hazard, personal injuries and
burns.)
If the booster battery is an extended maintenance interval
battery, it is not necessary to remove the vent plugs.
3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for about 5 minutes. During jump
starting, run the engine at about 2000 rpm with the accelerator
pedal lightly depressed.
4. Locate positive (+) and negative ( −) terminals of each
battery. Connect the jumper cables in the exact order (
1 2
3 4) shown in the illustration.
1 Connect a positive (red) jumper cable clamp to the
positive (+) terminal of the discharged battery.
2Connect the clamp at the other end of the positive (red)
cable to the positive (+) terminal of the booster battery.
3Connect a negative (black) cable clamp to the negative
(−) terminal of the booster battery.
4Connect the clamp at the other end of the negative (black)
cable to a solid, stationary, unpainted metallic point (e.g.
engine hanger) away from the battery. Do not connect it
to or near any part that moves when the engine is
cranked.
CAUTION
When making the connections, to avoid serious injury,
do not lean over the battery or accidentally let the
jumper cables or clamps touch anything except the
correct battery terminals or the ground.
5. Charge the discharged battery with the jumper cables
connected for approximately 5 minutes. At this time, run the
engine in the vehicle with the booster battery at about 2000
rpm with the accelerator pedal lightly depressed.
6. Start your engine in the normal way. After starting, run it at
about 2000 rpm for several minutes with the accelerator pedal
lightly depressed.
7. Carefully disconnect the cables in the exact reverse order:
the negative cable and then the positive cable.
8. Carefully dispose of the battery cover cloths which may now
contain sulfuric acid.
9. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for
example, lights left on), you should have it checked at your
Lexus dealer.
If the first start attempt is not successful...
Check that the clamp on the jumper cables are tight. Recharge
the discharged battery with the jumper cables connected for
several minutes and restart your engine in the normal way.
If another attempt is not successful, the battery may be
depleted. Have it checked at your Lexus dealer.
