WARNING

■

Things that must not be carried in the luggage compartment

The following things may cause a fire if loaded in the luggage compartment:

●

Receptacles containing gasoline

●

Aerosol cans

■

Storage precautions

Observe the following precautions.

Failure to do so may prevent the pedals from being depressed properly, may block the

driver’s vision, or may result in items hitting the driver or passengers, possibly causing

an accident.

●

Stow cargo and luggage in the luggage compartment whenever possible.

●

Do not stack cargo and luggage in the luggage compartment higher than the seat-

backs.

●

Do not place cargo or luggage in or on the following locations.
• At the feet of the driver

• On the front passenger or rear seats (when stacking items)

• On the luggage cover (if equipped)

• On the instrument panel

• On the dashboard

• On the auxiliary box or tray that has no lid

●

Secure all items in the occupant compartment.

●

When you fold down the rear seats, long items should not be placed directly behind

the front seats.

●

Never allow anyone to ride in the luggage compartment. It is not designed for pas-

sengers. They should ride in their seats with their seat belts properly fastened. Other-

wise, they are much more likely to suffer death or serious bodily injury, in the event of

sudden braking, sudden swerving or an accident.

■

Capacity and distribution

●

Do not exceed the maximum axle weight rating or the total vehicle weight rating.

●

Even if the total load of occupant’s weight and the cargo load is less than the total load

capacity, do not apply the load unevenly. Improper loading may cause deterioration

of steering or braking control which may cause death or serious injury.

191

WARNING

■

Roof luggage carrier precautions (if equipped)

To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or more

genuine Lexus cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:

●

Place the cargo so that its weight is distributed evenly between the front and rear

axles.

●

If loading long or wide cargo, never exceed the vehicle overall length or width.

(

P. 562)

●

Before driving, make sure the cargo is securely fastened on the roof luggage carrier.

●

Loading cargo on the roof luggage carrier will make the center of the vehicle gravity

higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt

maneuvers, otherwise it may result in loss of control or vehicle rollover due to failure

to operate this vehicle correctly and result in death or serious injury.

●

If driving for a long distance, on rough roads, or at high speeds, stop the vehicle now

and then during the trip to make sure the cargo remains in its place.

●

Do not exceed 154 lb. (70 kg) cargo weight on the roof luggage carrier.

NOTICE

■

Cross rail adjustment (if equipped)

Do not remove the cross rail stoppers, or the moon roof may be damage when it is

tilted.

■

When loading the luggage

Be careful not to scratch the surface of the moon roof.

193

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. For 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 performance are affected by trailer sta-
bility, brake performance and setting, trailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme care 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 commercial purposes.
Contact your Lexus dealer for further information about additional require-
ments such as towing kits, etc.

194

■

GCWR (Gross Combination Weight Rating)

The maximum allowable gross com-
bination weight. The gross combina-
tion weight is the sum of the total
vehicle weight (including the occu-
pants, cargo and any optional equip-
ment installed on the vehicle) and
the weight of the trailer being towed
(including the cargo in the trailer).

■

GVWR (Gross Vehicle Weight Rating)

The maximum allowable gross vehi-
cle weight. The gross vehicle weight
is the total weight of the vehicle.
When towing a trailer, it is the sum of
the vehicle weight (including the
occupants, cargo and any optional
equipment installed on the vehicle)
and the tongue weight.

■

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.

A recommended tongue weight varies in accordance with the types of trailers
or towing as described below.

●

To ensure the recommended values shown below, the trailer must be loaded
by referring to the following instructions.

• Tongue Weight

The gross trailer weight should be distributed so that the tongue weight is
9 % to 11 %. (Tongue weight/Gross trailer weight



100 = 9 % to 11 %)

Gross trailer weight
Tongue weight

If using a weight distributing hitch when towing, return the front axle to the
same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the front fender
height above the front axle before connection. Adjust weight distributing
hitch torque until front fender is returned to the same height as before con-
nection.
The gross trailer weight, gross axle weight and tongue weight can be mea-
sured with platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

Trailer hitch assemblies have different weight capacities. Lexus recommends the
use of Lexus hitch/bracket for your vehicle. For details, contact your Lexus
dealer.

●

If you wish to install a trailer hitch, contact your Lexus dealer.

●

Use only a hitch that conforms to the gross trailer weight requirement of your
vehicle.

●

Follow the directions supplied by the hitch manufacturer.

●

Lubricate the hitch ball with a light coating of grease.

●

Remove the hitch ball whenever you are not towing a trailer. Remove the
trailer hitch if you do not need it. After removing the hitch, seal any mounting
hole in the vehicle body to prevent entry of any substances into the vehicle.

Remove the clip.

Grasp the lower edge of the hitch
cover and raise the cover.

When reattaching the cover, reverse the

steps listed.

Your vehicle will handle differently when towing a trailer. Help to avoid an acci-
dent, death or serious injury, keep the following in mind when towing:

●

Speed limits for towing a trailer vary by state or province. Do not exceed the
posted towing speed limit.

●

Lexus recommends that the vehicle-trailer speed limit is 65 mph (104 km/h)
on a flat, straight, dry road. Do not exceed this limit, the posted towing speed
limit or the speed limit for your trailer as set forth in your trailer owner’s man-
ual, whichever is lowest. Instability of the towing vehicle-trailer combination
(trailer sway) increases as speed increases. Exceeding speed limits may cause
loss of control.

●

Before starting out, check the trailer lights, tires and the vehicle-trailer con-
nections. Recheck after driving a short distance.

●

Practice turning, stopping and reversing with the trailer attached in an area
away from traffic until you become accustomed to the feel of the vehicle-
trailer combination.

●

Reversing with a trailer attached 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 is generally opposite to reversing without a trailer attached.) Avoid sharp
or prolonged turning. Have someone guide you when reversing to reduce the
risk of an accident.

●

As stopping distance is increased when towing a trailer, vehicle-to-vehicle dis-
tance should be increased. For each 10 mph (16 km/h) of speed, allow at least
one vehicle and trailer length.

●

Avoid sudden braking as you may skid, resulting in the trailer jackknifing and
loss of vehicle control. This is especially true on wet or slippery surfaces.

Trailer towing tips

204

●

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 trailer wheels will be closer than the vehicle
wheels to the inside of the turn. Compensate 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. 217)

●

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, your 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 temperature gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. (

205

●

Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Apply the parking brake firmly, and put the transmission in P.
Avoid parking on a slope, but if unavoidable, do so only after performing the
following:

Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and trailer’s
wheels.
When the wheel blocks are in place, release the brakes slowly until the
blocks absorb the load.
Shift into P and apply the parking brake.
Turn off the engine.

●

When restarting after parking on a slope:

With the transmission in P, start the engine. Be sure to keep the brake pedal
pressed.
Shift into a forward gear. If reversing, shift into R.
If the parking brake is in manual mode, release the parking brake.
