To allow proper operation of your vehicle's ventilation system, keep
the inlet grilles in front of the windshield clear of snow, leaves, or
other obstructions.
If you smell exhaust fumes in the vehicle, drive with the windows
open and the trunk lid closed. Have the cause immediately located
and corrected.

DRIVING TIPS
156
Brakes and safety chains
Lexus recommends trailers with brakes that conform to any
applicable federal and state/provincial regulations.
A 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 (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 e ach time you hitch up. Direct
splicing may damage your vehicle's electrical system and cause a
malfunction of your lights.
Break±in 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 ºOwner's Manual Supplement/
Maintenance Scheduleº.
Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pre±towing 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 nose±up or
nose±down 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.
