DRIVING TIPS
186
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 (kgf/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.
Trailer lights
Trailer lights must comply with federal, state/provincial and local
regulations. See your local recreational vehicle dealer or rental
agency for the correct type of wiring and relays for your trailer.
Check for correct operation of the turn signals and stop lights
each time you hitch up. Direct splicing may damage your
vehicle’s electrical system and cause a malfunction of your lights.
Breakin schedule
Lexus recommends that you do not tow a trailer with a new
vehicle or a vehicle with any new power train component (engine,
transmission, differential, wheel bearing, etc.) for the first 800 km
(500 miles) of driving.
Maintenance
If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this information,
please refer to the scheduled maintenance information in the
”Owner ’s Manual Supplement/ Maintenance Schedule”.
Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pretowing safety check
Check that your vehicle remains level when a loaded or unloaded
trailer is hitched. Do not drive if the vehicle has an abnormal
noseup or nosedown condition, and check for improper tongue
load, overload, worn suspension or other possible causes.
Make sure the trailer cargo is securely loaded so that it cannot
shift.
Check that your rear view mirrors conform to any federal,
state/provincial or local regulation. If they do not, install required
rear view mirrors appropriate for towing purposes.

DRIVING TIPS
188Because 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 196 of this manual.
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 keep them applied.
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 ”3”, ”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 vehicletrailer 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.
