WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
●If the shift lever is moved before the low sp
eed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time, the indicator blinks and the buzzer
sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P.
You or someone else could be seriously injure d. You must complete the shifting of the
transfer mode. ( P. 3 0 5 )
●Do not touch the exhaust pipes while the engine is running or immediately after turn-
ing the engine off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to engine over-
heating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust gases
may collect and enter the vehicle, leadin g to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that re quire braking. In this case, braking is still
possible, but the brake pedal should be depressed more firmly than usual. Also, the
braking distance will increase. Have your brakes fixed immediately.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems: If one of the systems fails,
the other will still operate. In this case, the brake pedal should be depressed more
firmly than usual and the bra king distance will increase.
Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage th e driveline components or propel the vehi-
cle forward or backward, causing an accident.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as
this may restrain the engine output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is ac cidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering pump.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the follo wing situations. Hold the steering wheel
firmly and gradually depress the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire. (P. 5 3 6 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

Trailer towing
Your vehicle is designed primarily as
a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse impact on handling, performance, brak-
ing, durability, and fuel consumption. Fo r your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking pe rformance are affected by trailer sta-
bility, brake performance and setting, tr ailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme ca re and drive the vehicle in accordance
with your trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commer cial purposes.
Contact your Lexus dealer for further information about additional require-
ments such as towing kits, etc.

■GAWR (Gross Axle Weight Rating)
The maximum allowable gross axle
weight. The gross axle weight is the
load placed on each axle (front and
rear).
■TWR (Trailer Weight Rating)
The maximum allowable gross trailer
weight. The gross trailer weight is
the sum of the trailer weight and the
weight of the cargo in the trailer.
TWR is calculated assuming base
vehicle with one driver, one front
passenger, towing package (if avail-
able), hitch and hitch systems (if
required).
Additional optional equipment, passengers and cargo in the vehicle will reduce the
trailer weight rating so as not to exceed GCWR, GVWR and GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended to use a
trailer with 2 or more axles.

trailer without a trailer service brake
system.

●The gross trailer weight must never exceed 7000 lb. (3175 kg).
●The gross combination weight must never exceed 13400 lb. (6078 kg).
●The gross vehicle weight must never
exceed the GVWR indicated on the
Certification Label.
●The gross axle weight on each axle
must never exceed the GAWR indi-
cated on the Certification Label.
●If the gross trailer weight is over the unbraked TWR, trailer service brakes are
required.
●If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with
sufficient capacity is required.
●If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing
hitch with sufficient capacity is required.
Confirm that the gross trailer weight, gross combination weight, gross vehicle
weight, gross axle weight and tongue weight are all within the limits.

●Avoid jerky starts or sudden acceleration.
●Avoid jerky steering and sharp turns, and slow down before making a turn.
●Note that when making a turn, the traile
r wheels will be closer than the vehicle
wheels to the inside of the turn. Comp ensate by making a wider than normal
turning radius.
●Slow down before making a turn, in crosswinds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer.
●Take care when passing other vehicles. Passing requires considerable dis-
tance. After passing a vehicle, do not forget the length of your trailer, and be
sure you have plenty of room before changing lanes.
●To maintain engine braking efficiency and charging system performance
when using engine braking, do not put the transmission in D.
If in the S mode, the transmission shift range position must be in 6 or lower.
( P. 2 1 0 )
●Instability happens more frequently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending steep or long downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency.
●Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85°F [30°C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air cond itioning (if in use), pull your vehicle off the road and
stop in a safe spot. ( P. 5 5 6 )
