Also, even in heavy traffic conditions,
drive the vehicle in D or S.
*: When the hybrid battery (traction bat-tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop. ( P.68)
■During normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine via
the electric motor (traction motor).
■When braking (regenerative brak-
ing)
The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged.
■Regenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obta ined in conjunction
with the recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released while
driving with the shift lever in D or S.
●The brake pedal is depressed while driv-
ing with the shift lever in D or S.
■EV indicator
The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or th e gasoline engine is
stopped.
■Conditions in which the gasoline engine
may not stop
The gasoline engine starts and stops auto-
matically. However, it may not stop auto-
matically in the following conditions
*:
●During gasoline engine warm-up
●During hybrid battery (traction battery)
charging
●When the temperature of the hybrid bat-
tery (traction battery) is high or low
●When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop auto-
matically in other situations.
■Charging the hybrid battery (traction
battery)
As the gasoline engine charges the hybrid
battery (traction battery), the battery does
not need to be charged from an outside
source. However, if the vehicle is left parked
for a long time the hybrid battery (traction
battery) will slowly discharge. For this rea-
son, be sure to drive the vehicle at least
once every few months for at least 30 min-
utes or 10 miles (16 km ). If the hybrid bat-
tery (traction battery) becomes fully
discharged and you are unable to start the
hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
 P.414
■After the 12-volt battery has discharged
or when the terminal has been removed
and installed during exchange, etc.
The gasoline engine may not stop even if
the vehicle is being driven by the hybrid bat-
tery (traction battery). If this continues for a
few days, contact your Lexus dealer.

Driving
Your vehicle will handle differently
when towing a trailer. Help to avoid an
accident, death or serious injury, keep
the following in mind when towing:
 Speed limits for towing a trailer vary
by state or province. Do not exceed
the posted towing speed limit.
 Lexus recommends that the vehicle-
trailer speed limit is 65 mph (104
km/h) on a flat, straight, dry road.
Do not exceed this limit, the posted
towing speed limit or the speed limit
for your trailer as set forth in your
trailer owner’s manual, whichever is
lowest. Instability of the towing vehi-
cle-trailer combination (trailer
sway) increases as speed increases.
Exceeding speed limits may cause
loss of control.
 Before starting out, check the trailer
lights, tires and the vehicle-trailer
connections. Recheck after driving
a short distance.
 Practice turning, stopping and
reversing with the trailer attached in
an area away from traffic until you
become accustomed to the feel of
the vehicle-trailer combination.
 Reversing with a tr ailer attached is
difficult 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
your hand to the right to move the
trailer to right. (This is generally
opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to reduce
the risk of an accident.
 As stopping distance is increased
when towing a trailer, vehicle-to
vehicle distance should be
increased. For each 10 mph (16
km/h) of speed, allow at least one
vehicle and trailer length.
 Avoid sudden braking as you may
skid, resulting in the trailer jackknif-
ing and a loss of vehicle control. This
is especially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden accel-
eration.
 Avoid jerky steering and sharp
turns, and slow down before making
turn.
 Note that when making a turn, the
trailer wheels will be closer than the
vehicle wheels to the inside of the
turn. Compensate by making a
wider than normal turning radius.
 Slow down before making a turn, in
cross winds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can desta-
bilize the trailer.
 Take care when passing other vehi-
cles. Passing requires considerable
distance. After pass ing a vehicle, do
not forget the length of your trailer,
and be sure you have plenty of room
before changing lanes.
 To maintain engine braking effi-
ciency and charging system perfor-
mance when using engine braking,

Driving
*1: To improve fuel efficiency and reduce noise, shift the shift lever to D for normal
driving.
You can choose gear range suitable for
your driving situation by operating the
paddle shift switches.
*2: By selecting shift ra nges using S mode,
you can control accelerating force and
engine braking force.
■S mode
●When the shift range is 4 or lower, hold-
ing the shift lever towa rd “+” sets the shift
range to 6.
●Automatically selects a higher shift range
before the engine speed becomes too
high.
■When driving with dynamic radar cruise
control with full-speed range activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not activate
because dynamic radar cruise control with
full-speed range will not be canceled.
●While driving in S mode, downshifting to
5 or 4. ( P.181)
●When switching the driving mode to
Sport mode while driving in D position.
( P.269)
■Restraining sudden start (Drive-Start
Control)
When the following unusual operation is
performed, the hybrid system output may
be restrained.
●When the shift lever is shifted from R to D,
D to R, N to R, P to D, or P to R (D
includes S) with the accelerator pedal
depressed, a warning message appears
on the multi-information display. If a
warning message is shown on the multi-
information display, read the message
and follow the instructions.
●When the accelerator pedal is depressed

If the shift lever is in N, the hybrid battery
(traction battery) will not be charging,
even when the engine is running. There-
fore, if the vehicle is left with the shift
lever in N, the hybrid battery (traction
battery) will discharge, and this may
result in the vehicl e not being able to
start.
