. Always check your brakes for effectiveness immediately after driving in sand , mud or water . Do this by driving slowly and stepping on the brake pedal . Repeat that process several times to dry out the brake discs and brake pads .
. After driving through tall grass , mud , rocks , sand , rivers , etc ., check that there is no grass , bush , paper , rags , stones , sand , etc . adhering to or trapped on the underbody . Clear off any such matter from the underbody . If the vehicle is used with these materials trapped or adhering to the underbody , a mechanical breakdown or fire could occur .

Carry some emergency equipment , such as a window scraper , a bag of sand , flares , a small shovel and jumper cables .
Check the battery and cables . Cold temperatures reduce battery capacity . The battery must be in good condition to provide enough power for cold winter starts .
It normally takes longer to start the engine in very cold weather conditions . Use an engine oil of a proper grade and viscosity for cold weather . Using heavy summer oil will make it harder to start the engine .
Keep the door locks from freezing by squirting them with deicer or glycerin .
Forcing a frozen door open may damage or separate the rubber weather strips around the door . If the door is frozen , use hot water to melt the ice , and afterwards thoroughly wipe the water away .
Use a windshield washer fluid that contains an antifreeze solution . Do not use engine antifreeze or other substitutes because they may damage the paint of
the vehicle .
If you fill the reservoir tank with a fluid with a different concentration from the one used previously , purge the old fluid from the piping between the reservoir tank and washer nozzles by operating the washer for a certain period of time . Otherwise , if the concentration of the fluid remaining in the piping is too low for the outside temperature , it may freeze and block the nozzles .
CAUTION
. Adjust the washer fluid concentration appropriately for the outside temperature . If the concentration is inappropriate , sprayed washer fluid may freeze on the windshield and obstruct your view , and the fluid may freeze in the reservoir tank .
. State or local regulations on volatile organic compounds may restrict the use of methanol , a common windshield washer antifreeze additive . Washer fluids containing non-methanol antifreeze agents should be used only if they provide cold weather protection without damaging your vehicle ’ s paint , wiper blades
