Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate for the
prevailing weather and roadway conditions.
■ Pre-winter preparations
●Use fluids appropriate to the p revailing outside temperatures.
• Engine oil
• Engine coolant
• Washer fluid
●Inspect the level and specific gravity of battery electrolyte.
●Have the vehicle fitted with four sno w tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same si
ze and brand, and that chains
match the size of the tires.
■ Befor
e driving the vehicle
Perform the following steps acco r
ding to the driving conditions.
●Do not forcibly try to open a window or move a wiper that has fro-
zen. Pour some warm water over the frozen area to melt the ice. 
Wipe away the water immediately to pr
event it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in front
of the windshield.
●Remove any ice that has accumulated on the vehicle chassis.
●Periodically check for and remove any excess ice or snow that may
accumulate in the wheel well or brakes.

When driving
• As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
• Avoid sudden braking as you may sk id, r
esulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
• Avoid jerky starts or sudden acceleration.
• Avoid jerky steering and sharp turn s, and slo
w down before making a
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the
v
ehicle wheels to the inside of th e turn. Compensate by making a
larger than normal turning radius.
• Crosswinds and rough roads will ad v
ersely affect handling of your
vehicle and trailer, causing sway. Peri odically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If s
waying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
assing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
• In order to maintain efficient engine br
aking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. See “If your vehicle
overheats” ( P.359 ).
