Total trailer weight Tongue load
The trailer cargo load should be distributed so that
the tongue load is 9 to 11% of the total trailer weight,
not exceeding the maximum of 90 kg (200 lb.).
 Never load the trailer with more weight in the back
than in the front. About 60% of the trailer load should
be in the front half of the trailer and the remaining 40%
in the rear.
Hitches
If you wish to install a trailer hitch, your Lexus dealer should
be consulted.
 Use only a hitch which is recommended by Lexus dealer
and conforms to the total trailer weight requirement.
 Follow the directions supplied by the hitch manufacturer.
Lubricate the hitch ball with a light coat of grease.
 Lexus recommends removing the trailer hitch whenever you
are not towing a trailer to reduce the possibility of additional
damage caused by the hitch if your vehicle is struck from
behind. After removing the hitch, seal any mounting holes
in the vehicle body to prevent entry of pollutants such as
exhaust fumes, dirt, water, etc.
NOTICE
 Install the trailer hitch using only the position
recommended by your Lexus dealer. Do not install
the trailer hitch on the bumper; this may cause body
damage.
 Do not use axlemounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels
or tires.

DRIVING TIPS
287
Brakes and safety chains
Lexus recommends trailers with brakes that conform to
any applicable federal and state/provincial regulations.
 A safety chain must always be used between the towing
vehicle and the trailer. Leave sufficient slack in the
chain for turns. The chain should cross under the
trailer tongue to prevent the tongue from dropping to
the ground in case it becomes damaged or separated.
For correct safety chain procedures, follow the hitch or
trailer manufacturer’s recommendations.
CAUTION
 If the total trailer weight exceeds 500 kg (1102 lb.),
trailer brakes are required.
 Never tap into your vehicle’s hydraulic system as it
will lower its braking effectiveness.
 Never tow a trailer without using a safety chain
securely attached to both the trailer and the vehicle.
If damage occurs to the coupling unit or hitch ball,
there is possible danger of the trailer wandering over
into another lane.
Tires
Ensure that your vehicle’s tires are properly inflated. Adjust
the tire inflation pressure to the recommended cold tire
inflation pressure indicated below:
Tire inflation pressure, kPa (kgf/cm
2 or bar, psi)
P215/60R16 94V Front 200 (2.0, 29) Rear 200 (2.0, 29)
P215/55R17 93V Front 220 (2.2, 32) Rear 220 (2.2, 32)
 The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.
Trailer lights
Trailer lights must comply with federal, state/provincial and
local regulations. See your local recreational vehicle dealer
or rental agency for the correct type of wiring and relays for
your trailer. Check for correct operation of the turn signals
and stop lights each time you hitch up. Direct splicing may
damage your vehicle’s electrical system and cause a
malfunction of your lights.
Breakin schedule
 Lexus recommends that you do not tow a trailer with a new
vehicle or a vehicle with any new power train component
(engine, transmission, differential, wheel bearing, etc.) for
the first 800 km (500 miles) of driving.

DRIVING TIPS
288
Maintenance
If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this
information, please refer to the scheduled maintenance
information in the “Owner’s Manual Supplement/
Scheduled Maintenance”.
 Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
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.

DRIVING TIPS
291

Avoid engine overrevving. Use a gear position suitable
for the road on which you are traveling.
 Avoid continuous speeding up and slowing down.
Stop−and−go driving wastes fuel.
 Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time the traf fic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.
 Avoid heavy traffic or traffic jams whenever possible.
 Do not rest your foot on the brake pedal. This causes
premature wear, overheating and poor fuel economy.
 Maintain a moderate speed on highways. The faster you
drive, the greater the fuel consumption. By reducing your
speed, you will cut down on fuel consumption.
 Keep the front wheels in proper alignment. Avoid hitting
the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.
 Keep the bottom of your vehicle free from mud etc. This
not only lessens weight but also helps prevent corrosion. 
Keep your vehicle tunedup and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive under
severe conditions, see that your vehicle receives more
frequent maintenance. (For scheduled maintenance
information, please refer to the “Owner’s Manual
Supplement/Scheduled Maintenance”.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.

IN CASE OF AN EMERGENCY

IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Turn the ignition key to “ACC” or “LOCK”, and try starting the
engine again.
If the engine will not start, see “If your vehicle will not start”\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in “How to start the
engine” on page 259 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobilizer system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, there may be a
malfunction in the immobilizer system. Call your Lexus dealer.
See “Keys” on page 10.
If the engine is not turning over or is turning over too
slowly —
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See “(c)
Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
“Foreword”.)

IN CASE OF AN EMERGENCY
300
(c) Jump starting
To avoid serious personal injury and damage to your
vehicle which might result from battery explosion, acid
burns, electrical burns, or damaged electronic
components, these instructions must be followed
precisely.
If you are unsure about how to follow this procedure, we
strongly recommend that you seek help from your Lexus
dealer, Roadside Assistance or Customer Service Assistance.
(See “Foreword”.)
CAUTION
 Batteries contain sulfuric acid which is poisonous
and corrosive. Wear protective safety glasses when
jump starting, and avoid spilling acid on your skin,
clothing, or vehicle.
 If you should accidentally get acid on yourself or in
your eyes, remove any contaminated clothing and
flush the affected area with water immediately. Then
get immediate medical attention. If possible,
continue to apply water with a sponge or cloth while
en route to the medical office.
 The gas normally produced by a battery will explode
if a flame or spark is brought near. Use only
standardized jumper cables and do not smoke or
light a match while jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump
start unless you are sure that the booster battery is
correct.

1. If the booster battery is installed in another vehicle, make
sure the vehicles are not touching. Turn off all unnecessary
lights and accessories.
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.

IN CASE OF AN EMERGENCY
3024. Locate positive (+) and negative (
−) terminals of each
battery. Connect the jumper cables in the exact order (
1 23 4) shown in the illustration.
1Connect 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.
cylinder head) 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. Start your engine in the normal way. After starting, run it at
about 2000 rpm for several minutes with the accelerator pedal
lightly depressed.
6. Carefully disconnect the cables in the exact reverse order:
the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may now
contain sulfuric acid.
8. 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 the another attempt is not successful, the battery may be
depleted. Have it checked at your Lexus dealer.
