■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery de pletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak ra dio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless re mote control and immobilizer system from
operating properly. (Ways of coping: P. 527)
●When the electronic key battery is depleted

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.

2144-1. Before driving
GS450h_300h_OM_OM30F92E_(EE) Your vehicle will handle differently when towing a trailer
. In order to avoid acci-
dent, death or serious injury, keep the following in mind when towing:
■Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection between the
trailer and lights after driving for a brief period as well as before starting off.
■Practicing driving with a coupled trailer ●Get the feel for turning, stopping an d reversing with the trailer coupled by
practicing in an area with no or light traffic.
● When reversing with a coupled trailer, hold the section of the steering
wheel nearest to you and rotate clockwise to turn the trailer left or counter-
clockwise to turn it right. Always rotate a little at a time to prevent steerin g
error. Have someone guide you when reversing to lessen the risk of an
accident.
■Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle runni ng ahead of
you should be equivalent to or greater than the combined length of your v ehi-
cle and trailer. Avoid sudden braking that may cause skidding. Otherwise, the
vehicle may spin out of control. This is especially true when driving on wet or
slippery road surfaces.
■Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer colliding with your
vehicle. Decelerate well in advance when approaching turns and take them
slowly and carefully to avoid sudden braking.
■Important points regarding turning
The wheels of the trailer will travel closer to the inside of the curve than the
wheels of the vehicle. To make allowance for this, take the turns wider than you
would normally do.
■Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong cross-
winds will affect handling. The vehicle may also be rocked by passing buses or
large trucks. Frequently check behind when moving alongside such vehicles.
As soon as such vehicle movement occurs, immediately start to decelerate
smoothly by slowly applying the brakes. Always steer the vehicle straight
ahead while braking.
