DRIVING TIPS
144Lexus 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.
CAUTION:
The rear bumper reinforcement is made of aluminum, so
do not allow steel hitch parts to come in direct contact
with it. When steel and aluminum are in contact, a galvanic
reaction (electrolytic corrosion) occurs which can
weaken the strength of the contacting parts and cause
damage. When installing a steel hitch, apply paint, etc. to
the contacting surfaces to prevent corrosion.
NOTICE:
Do not use axle-mounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels or
tires.
Brake and safety chains
Lexus recommends trailers with brakes that conform to
any applicable federal and state / provincial
regulations.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 450 kg (1000 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 pressure to the recommended cold tire pressure
indicated below:
Tire pressure, kPa (kg / cm
2 or bar, psi)
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.

Backing your trailer
Left turnRight turn
Backing with a trailer 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 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.
Avoid jerky starts or sudden acceleration.
Avoid jerky steering and sharp turns. The trailer could hit
your vehicle in a tight turn. Slow down before making a turn
to avoid the necessity of sudden braking.Remember that when making a turn, the trailer wheels will
be closer than the vehicle wheels to the inside of the turn.
Therefore, compensate for this by making a larger than
normal turning radius with your vehicle.
Crosswinds and rough roads will adversely affect handling
of your vehicle and trailer, causing sway. Pay attention to the
rear from time to time to prepare yourself for being passed
by large trucks or buses, which may cause your vehicle and
trailer to sway. If swaying happens, firmly grip the steering
wheel and reduce speed immediately but gradually. Never
increase speed. If it is necessary to reduce speed, brake
slowly. Steer straight ahead. If you make no extreme
correction with the steering or brakes, your vehicle and
trailer will stabilize.
Be careful when passing other vehicles. Passing 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 braking and electrical
charging performance, do not use overdrive.
Because of the added load of the trailer, your vehicle’s
engine may overheat on hot days (at temperatures over
30C [85F]) when going up a long or steep grade with a
trailer. 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” on page 152 of this manual.
