Before driving
CAUTION
■Refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may
r
esult in death or serious injury.
• Touch the vehicle or some other metal surf ace to dischar
ge any static electricity.
Sparks resulting from discharging static electricity may cause the fuel vapors to
ignite.
• Always hold the grip on the fuel tank cap and turn it slowly to remove it. A whooshin
g sound may be heard when the fu el tank cap is loosened. Wait until
the sound cannot be heard before fully removing the cap. In hot weather, pres -
surized fuel may spray out the filler neck and cause injury.
• Do not allow any one that has not discharge
d static electricity from their bodies,
to come close to an open fuel tank.
• Do not inhale vaporized fuel. 
Fuel contains substances that are harmful to the human body, if inhaled.
• Do not smoke while refueling the vehicle. 
Doing so may cause the fuel to ignite and cause a fire.
• Do not return to the vehicle or touch an y perso
n or object that is statically
charged. 
This may cause static electricity to build up, resulting in a possible ignition haz -
ard.
■Fuel cap precaution
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
F

ailure to do so may cause a fire or other incident which may result in death or seri -
ous injury.
NOTICE
■Refueling
Observe the following precautions when refueling the vehicle. 
Failing to do so damages the vehicle, su ch
as causing the exhaust systems to oper -
ate abnormally or damaging fuel system c
omponents or the vehicle’s painted sur-
face.
• Do not use any type of gasoline other than as recommended. ( P.373 )
• Do not spill fuel during refueling.

2-5. Driving information

When driving
• As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
• Avoid sudden braking as you may sk id, r
esulting 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 turn s, and slo
w down before making a
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the
v
ehicle wheels to the inside of th e turn. Compensate by making a
larger than normal turning radius.
• Crosswinds and rough roads will ad v
ersely affect handling of your
vehicle and trailer, causing sway. Peri odically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If s
waying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
assing 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 br
aking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. 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” ( P.359 ).
