DRIVING TIPS
144
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.
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.

DRIVING TIPS
147
Always place wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put
the transmission in “P”. Avoid parking on a slope with a
trailer, but if it cannot be avoided, do so only after performing
the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks under both the vehicle
and trailer wheels.
3. When the wheel blocks are in place, release your brakes
slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into “P” and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in “P” position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the “2”, “L” or “R” position.
3. Release the parking brake and brake pedal and slowly pull
or back away from the wheel blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.
CAUTION:

Do not exceed 72 km / h (45 mph) or the posted towing
speed limit, whichever is lower. Because instability
(swaying) of a towing vehicle-trailer combination
usually increases as the speed increases, exceeding 72
km / h (45 mph) 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.
HOW TO SAVE FUEL AND MAKE
YOUR VEHICLE LAST LONGER
Getting more kilometers / mileage from a liter / gallon of fuel is
easy − just take it easy. It will help make your vehicle last
longer, too. Here are some specific tips on how to save money
on both fuel and repairs:

Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.

Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.

Avoid lengthy warm-up idling. Once the engine is running
smoothly, begin driving − but gently. Remember, however,
that on cold winter days this may take a little longer.

Accelerate slowly and smoothly. Avoid jackrabbit starts.
