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 steering 
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 running ahead of 
you should be equivalent to or greater than the combined length of your vehi- 
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.

Maintenance and care
GS450h_300h_OM_OM30F92E_(EE)
■Adding engine oil 
If the oil level is below or near the low level mark, add engine oil of the same 
type as that already in the engine. 
Make sure to check the oil type and prepare the items needed before adding 
oil. 
Remove the oil filler cap by turning it counterclockwise. 
Add engine oil slowly, checking the dipstick. 
Install the oil filler cap by turning it clockwise.
■Engine oil consumption 
A certain amount of engine oil will be consum ed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oilmaintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or afterreplacing the engine
●If low quality oil or oil of an  inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, when towing, or when driving while accelerating or decelerating frequently
●When leaving the  engine idling for a long time, or when driving frequently through 
heavy traffic
