When driving
CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed 
2000 lb. (907 kg).
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle 
weight and trailer tongue load capacities.
●Never load more weight in the back than  in the front of the trailer. About 60% of 
the load should be in the front half of the trailer, and the remaining 40% in the 
rear.
■Hitches
Trailer hitch assemblies have different weight capacities established by the hitch 
ma
nufacturer. Even though the vehicle may be physically capable of towing a 
higher weight, the operator must never  exceed the maximum weight rating speci -
fied for the trailer hitch.
• If you wish to install a trailer hitch,  your Lexus dealer should be consulted.
• Use only a hitch that 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.
• Remove the trailer hitch whenever you are not towing a trailer.  After  r
 emoving the hitch, seal any mounting holes in the vehicle body to prevent 
entry of any substances into the vehicle.
■When towing a trailer
●If the total trailer weight exceeds 1000 lb . (450 kg), trailer brakes are required.
●Never tap into your vehicle's hydraulic system, as this will lower the vehicle's 
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 
danger of the trailer wandering into another lane.

Trailer towing tips
Your vehicle will handle differently when towing a trailer. The three main 
causes of vehicle-trailer accidents are driver error, excessive speed and 
improper trailer loading. Keep these in mind when towing.
• Before starting out, check the tra iler
 ’s lights and the vehicle-trailer 
connections. Recheck after driving a short distance.
• Practice turning, stopping and reversi ng with the tr
 ailer attached in an 
area away from traffic until you be come accustomed to the feel of the 
vehicle. 
• Reversing with a trailer attached is  dif
 ficult 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 yo ur hand to the right to move the 
trailer to the right. (This is gene rally opposite to reversing without a 
trailer attached.) Avoid sharp or  prolonged turning. Have someone 
guide you when reversing to redu ce the risk of an accident.
NOTICE
■When installing a trailer hitch
●Use 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 axle-mounted hitches as they  can cause damage to the axle housing, 
wheel bearings, wheels or tires.
■Brakes
Lexus recommends trailers with brakes that conform to any applicable federal and 
sta
te/provincial requlations.
■Do not directly splice trailer lights
Direct splicing may damage your vehicle’s electrical system and cause a malfunc -
tion.

When driving
• As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of 
speed, allow at least one vehicle and trailer length. 
• Avoid sudden braking as you may sk id, r
 esulting 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 turn s, and slo
 w down before making a 
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the 
v
 ehicle wheels to the inside of th e turn. Compensate by making a 
larger than normal turning radius.
• Crosswinds and rough roads will ad v
 ersely affect handling of your 
vehicle and trailer, causing sway. Peri odically check the rear to prepare 
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway.  If s
 waying occurs, firmly grip the steering wheel, 
reduce speed immediately but gradually, and steer straight ahead. 
Never increase speed. If you make no extreme correction with the 
steering or brakes, your vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
 assing 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 br
 aking and electrical charging 
performance, do not use overdrive.  Transmission shift range position 
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
 , 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, immediately turn off the  air conditioning (if in use), pull 
your vehicle off the road  and stop in a safe spot. See “If your vehicle 
overheats” ( P.359 ).

2-5. Driving information
• Always place wheel blocks under both the vehicle and the trailer 
wheels when parking. Apply the pa rking brake firmly, and put the 
transmission in “P”. Avoi d 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 v
 ehicle and 
trailer wheels.  
When the wheel blocks are in pl ace, r
 elease the brakes slowly 
until the blocks absorb the load.  
Apply the parking brake firmly.  
Shift into “P” and turn off the engine.
• When restarting after parking on a slope:
With the transmission in the “P” position, star
 t the engine. Be sure 
to keep the brake pedal pressed.
Shift into “3”, “2”, “1”, or  the “R” position (if r
 eversing).
Release the parking brake and br ak
 e pedal, and slowly pull or 
back away from the wheel blocks. 
Stop and apply the brakes.
Have someone retrieve the blocks.

When driving
CAUTION
■To avoid an accident
●Do not exceed 45 mph (72 km/h) or the posted towing speed limit, whichever is 
lower. As instability (swaying) of the towing vehicle-trailer combination increases 
as speed increases, exceeding 45 mph (72 km/h) may cause loss of control.
●Slow down and downshift before descending steep or long downhill grades. Do 
not make sudden downshifts.
●Avoid holding the brake pedal down too long or too frequently. This could cause 
the brakes to overheat and result in reduced braking efficiency
