When driving
WARNING
●Always check that all passengers' arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
●Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■When shifting the select lever or shift lever
●On vehicles with an automatic transmission, be careful not to shift the
select lever with the accelerator pedal depressed. Shifting the select lever
to a gear other than P or N may lead to unexpected rapid acceleration of
the vehicle that may cause an accident and result in death or serious
injury.
●Do not place items in the select lever’s or shift lever’s surrounding area. It
may cause incorrect operation.
●If the select lever’s or shift lever’s boot is pulled out during cleaning, return
it to its previous position. If the select lever’s or shift lever’s boot is left
pulled out, the select lever or shift lever may become difficult to operate.
