
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds 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.

Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before execut-
ing lane changes.

Transmission information
To maintain engine braking efficiency, when using engine braking
when driving on a long steep downward grade, do not use the transmis-
sion in D. The vehicle must be driven in gear shift position “4” in M
mode. (


If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures exceed-
ing 30

C (85

F) may result in the engine overheating. If the engine
coolant temperature gauge indicates that the engine is overheating, turn
the air conditioning off immediately, leave the road and stop the vehi-
cle in a safe place.

When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and
trailer. Firmly set the parking brake and shift the shift lever to P.
