maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly and result in death or serious injury.●
If driving for a long distance, on rough road s, or at high speeds , stop the vehicle now
and then during the trip to make sure the cargo remains in its place.●
Do not exceed 154 lb. (70 kg) cargo weight on the roof luggage carrier.■
