¼ Before operating the vehicle, ensure that the driver and all passengers have their seat belts fastened. ¼ Always drive with the floor mats in place as the floor may become very hot. Particular care should be taken if you are barefoot. ¼ Lower your speed when encountering strong crosswinds. With its higher center of gravity, your NISSAN is more affected by gusty side winds. Slower speeds ensure better vehicle control. ¼ Do not drive beyond the performance of the tires even with 4WD. ¼ Accelerating quickly, steering or braking may cause loss of control. ¼ Install the same size of winter tires on all four (four) wheels (such as studless tires) or install tire chains to the rear wheels when driving on slippery roads (e.g., after a snow) and drive carefully using 4WD. ¼ Be sure to check the brakes immediately after driving in mud or water as specified in ''Wet brakes'' under the heading ''Brake system,'' later in this section. ¼ Avoid parking your vehicle on steep hills. If you get out of the vehicle and it rolls forward, backward or sideways, you could be injured. ¼ Whenever you drive off-road through sand, mud or water as deep as the wheel hub, more frequent maintenance may be required. For details, refer to ''Maintenance for offroad driving'' in the ''Maintenance'' section of this manual.
