DRIVING ON SLIPPERY SURFACES
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed: 1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front to avoid a collision in a sudden stop.
DRIVING OFF-ROAD
Care should be taken when attempting to climb steep
hills or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously.298 STARTING AND OPERATING

Draining Fuel/Water Separator Filter (Diesel
Engines)
CAUTION!Do not drain the fuel/water separator filter when the
engine is running. CAUTION!Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility debris could be
introduced into the fuel filter during this action. It is
best to install the filter dry and allow the in-tank lift
pump to prime the fuel system.
NOTE: Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact your local dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
Drain a small amount from the fuel/water separator
filter monthly or when the WATER IN FUEL indicator
lamp is on. Turn the drain valve, located on the bottom of410 MAINTAINING YOUR VEHICLE

the filter, counterclockwise and allow any accumulated
water to drain. Leave the drain valve open until all water
and contaminants have been removed. Close the drain
valve, by turning it clockwise, when clean fuel is visible.
NOTE: The Fuel / Water separator drain valve is
located on the bottom of the fuel filter housing.
If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”
WARNING!Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death. Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.
4. Repeat the procedure if the engine does not start. MAINTAINING YOUR VEHICLE 411
