When driving
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents. 
Failing to do so may result in a loss of vehicle control and cause death or serious
injur
y.
• Use tires of the specified size.
• Maintain the recommended level of air pressure.
• Do not drive in excess of 72 mph (120 km/h), regardless of the type of snow tir
es being used.
• Use snow tires on all, not just some wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents. 
Failing to do so may result in to the vehicle being unable to be driven safely and a
p
ossible accident which may cause death or serious injury.
• Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
• Avoid driving on bumpy road s
urfaces or through potholes.
• Avoid sudden turns and braking, as us e of chains may a
dversely affect vehi-
cle handling.
• Slow down sufficiently before entering a curve to ensure that vehicle con -
trol is maintained.

■Before towing
●Ensure that your vehicle’s tires are properly inflated. (P.283 )
●Trailer tires should be inflated according to the trailer manufacturer’s recom -
mendation.
●All trailer lights must work to be legal.
●Confirm all lights work each time you connect them.
●Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
●Make sure the trailer cargo is securely loaded.
●Check that your rear view mirrors conform to any federal, state/provincial or
local regulations. If they do not, instal l rear view mirrors appropriate for towing
purposes.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
p

ower train components (engine, transmissi on, differential, wheel bearing, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (see “Owner’s Manual Supplement/ Scheduled Mainte -
nance”)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

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.

4-3. Do-it-yourself maintenance
■When to replace your vehicle’s tires
If either of the following occurs, the tire should be replaced:
• Tire damage such as cuts, splits, cracks deep enough to expose the
fabric, or bulges indicating internal damage
• If a tire often goes flat or cannot be pr
operly repaired due to the size
or location of a cut or other damage
If you are not sure, see your Lexus dealer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has
ne

ver or seldom been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Tire selection
When replacing a tire, use a tire of the sa me siz
e and construction, and the same or
greater maximum load as the originally installed tires.
Check that the maximum load of the replaced t
ire is greater than 1 /2 of the Gross
Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is
greater. 
As for the maximum load of the tire, see the load limit a
t maximum cold tire inflation
pressure mentioned on the sidewall of the tire. 
As for the Gross Axle Weight Ratings (GAWR), see the Certification Label. 
