OPERATION IN FOREIGNCOUNTRIES
If you plan to drive your Lexus in another country...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded
and minimum octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS
Always slow down in gusty crosswinds. This will allow you
much better control.
 Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp −edged objects and other
road hazards. Failure to do so can lead to severe tire
damage such as a tire burst.
Drive slowly when passing over bumps or travelling on a
bumpy road. Otherwise, the impact could cause severe
damage to the tires and/or wheels.
 When parking on a hill, turn the front wheels until they touch
the curb so that the vehicle will not roll. Apply the parking
brake, and place the trans mission in “P”. If necessary, block
the wheels.
 Washing your vehicle or driving through deep water may get
the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work safely, pull to the side of the
road and call a Lexus dealer for assistance.

DRIVING TIPS
471
CAUTION
Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
 Do not leave your vehicle unattended while the
engine is running.
 Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.
 To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 392 or 403.
 Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to skid or spin.
Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has highspeed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are highspeed
capability tires or not before driving at such speeds.
 Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.
 Vehicles with electronically modulated air
suspension: If you drive through water, such as when
crossing swallow streams, first check the depth of
the water and the bottom of the river bed of firmness,
put the vehicle height in the “HI” (high) mode with the
height select switch and then turn off the
electronically modulated air suspension by pushing
the height control switch. Drive your vehicle at 30
km/h (19 mph) or lower speed.

472
OFFROAD DRIVINGPRECAUTIONS
When driving your vehicle off −road, please observe the
following precautions to ensure your driving enjoyment and to
help prevent the closure of areas to off −road vehicles.
a. Drive your vehicle only in areas where off −road vehicles are
permitted to travel.
b. Respect private property. Get owner’s permission before
entering private property.
c. Do not enter areas that are closed. Honor gates, barriers
and signs that restrict travel.
d. Stay on established roads. When conditions are wet,
driving techniques should be changed or travel delayed to
prevent damage to roads. For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your
vehicle off
−road, consult the following organizations.
 State and Local Parks and Recreation Departments
 State Motor Vehicle Bureau
 Recreational Vehicle Clubs
 U.S. Forest Service and Bureau of Land Management
CAUTION
Always observe the following precautions to minimize
the risk of serious personal injury or damage to your
vehicle:
Drive carefully when off the road. Do not take
unnecessary risks by driving in dangerous places.
 Do not grip the steering wheel spokes when driving
offroad. A bad bump could jerk the wheel and injure
your hands. Keep both hands and especially your
thumbs on the outside of the rim.
 Always check your brakes for effectiveness
immediately after driving in sand, mud, water or
snow.

DRIVING TIPS
473
After driving through tall grass, mud, rock, sand,
rivers, etc., check that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or trapped on the
underbody. Clear off any such matter from the
underbody. If the vehicle is used with these materials
trapped or adhering to the underbody, a breakdown
or fire could occur.
 In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing
a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is
moving.
 When driving offroad or in rugged terrain, do not
drive at excessive speeds, jump, make sharp turns,
strike objects, etc. This may cause loss of control or
vehicle rollover causing death or serious injury. You
are also risking expensive damage to your vehicle’s
suspension and chassis.NOTICE
 If driving through water, such as when crossing
shallow streams, first check the depth of the water
and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
 Take all necessary safety measures to ensure that
water damage to the engine or other components
does not occur.
Water entering the engine air intake will cause severe
engine damage.
Water can wash the grease from wheel bearings,
causing rusting and premature failure, and may also
enter the differentials, transmission and transfer
case, reducing the gear oil’s lubricating qualities.
 Sand and mud that has accumulated in brake drums
and around brake discs may affect braking ef ficiency
and may damage brake system components.
 Always perform a maintenance inspection after each
day of offroad driving that has taken you through
rough terrain, sand, mud, or water. For scheduled
maintenance information, refer to the “Owner’s
Manual Supplement / Scheduled Maintenance”.

DRIVING TIPS
474
WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Only use “Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non−silicate, non −amine,
non− nitrite, and non −borate coolant with long− life hybrid
organic acid technology. (Coolant with long −life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)
See “Checking the engine coolant level” on page 559 for
details of coolant type selection.
For the U.S.A. — “T oyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about −35C (− 31F).
For Canada — “Toyota Super Long Life Coolant” is a mixture
of 55% coolant and 45% deionized water. This coolant
provides protection down to about −42C (− 44F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 601 tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold
weather.
See page 558 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer — they will be pleased to help.
Check the electronic ignition system for loose
connections or obvious damage.
Keep the door locks from freezing.
Squirt lock de− icer or glycerine into the locks to keep them from
freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer’s directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.

DRIVING TIPS
475
Do not use your parking brake when there is a possibility
it could freeze.
When
parking, put the transmission into “P” and block the rear
wheels. Do not use the parking brake, or snow or water
accumulated in and around the parking brake mechanism may
freeze the parking brake, making it hard to release.
Keep ice and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.
DINGHY TOWING
Your vehicle is not designed to be dinghy towed (with four
wheels on the ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four wheels on the ground.
This may cause serious damage to your vehicle.

DRIVING TIPS
476
TRAILER TOWING
Your vehicle is designed primarily as a passenger−and−load
carrying vehicle. T owing a trailer will have an adverse ef fect on
handling, performance, braking, durability and driving
economy (fuel consumption, etc.). Y our safety and satisfaction
depend on the proper use of correct equipment and cautious
driving habits. For your safety and the safety of others, you
must not overload your vehicle or trailer. Lexus warranties do
not apply to damage or malfunction caused by towing a trailer
for commercial purposes. Ask your local Lexus dealer for
further details before towing.
CAUTION
Vehicles with electronically modulated air suspension:
When disconnecting a trailer, put the vehicle height in
the “LO” mode and push the height control switch to
turn off the electronically modulated air suspension.
Otherwise, the vehicle height may be changed in the
automatic leveling function, resulting in unexpected
accident. For details see “Electronically modulated air
suspension” on page 437.
NOTICE
When towing a trailer, be sure to consult your Lexus
dealer for further information on additional
requirements such as a towing kit, etc.

DRIVING TIPS
477
Weight limits
Before towing, make sure the total trailer weight, gross
vehicle weight, gross axle weight and trailer tongue load
are all within the limits.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.
Certification label
CAUTION
The total trailer weight (trailer weight plus its cargo
load) must not exceed the following. Exceeding this
weight is dangerous. Without towing package 907 kg (2000 lb.)
With towing package 1588 kg (3500 lb.)
 If towing a trailer and cargo weighing over 907 kg
(2000 lb.), Lexus recommends to use a sway control
device with sufficient capacity. The gross
combination weight (sum of your vehicle weight plus
its load and the total trailer weight) must not exceed
the following. Without towing package 3286 kg (7245 lb.)
With towing package 3966 kg (8745 lb.)
 Trailer hitch assemblies have different weight
capacities established by the hitch manufacturer.
Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine
the maximum weight rating of the particular hitch
assembly and never exceed the maximum weight
rating specified for the trailer hitch. Exceeding the
maximum weight rating set by the trailer hitch
manufacturer can cause an accident resulting in
serious personal injuries.

DRIVING TIPS
478
The gross vehicle weight must not exceed the Gross
Vehicle Weight Rating (GVWR) indicated on the
Certification Label. The gross vehicle weight is the
sum weight of the unloaded vehicle, driver,
passengers, luggage, hitch and trailer tongue load.
It also includes the weight of any special equipment
installed on your vehicle.
 The load on either the front or rear axle resulting from
distribution of the gross vehicle weight on both axles
must not exceed the Gross Axle Weight Rating
(GAWR) listed on the Certification Label.
 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 the following.
Without towing package 90 kg (200 lb.)
With towing package 158 kg (350 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.
Tongue load
Total trailer weight 
100 = 9 to 11%

DRIVING TIPS
479
Tow hitch receiver
The tow hitch receiver is installed under the rear bumper.
CAUTION
A tow hitch receiver is rated for weight carrying towing
only up to the following. Only use this tow hitch receiver
on your vehicle. Do not use this tow hitch receiver on
any other vehicle. Without towing package 907 kg (2000 lb.)
With towing package 1588 kg (3500 lb.)
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.
