Apply just enough power to the wheels to
climb the hill. Too much power causes the
tires to slip, spin or lose traction, and you
could lose control of your vehicle. When
descending a steep hill, do not descend the
hill in neutral. Avoid sudden hard braking to
keep the front wheels rolling and to maintain
your vehicle's steering.
Note:
Your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes.
Note: If your vehicle gets stuck driving on
hilly or sloping terrain, it could be rocked out
by shifting between forward and reverse
gears, stopping between shifts in a steady
pattern. Press lightly on the accelerator in
each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires could occur or the engine could
overheat. DRIVING IN SAND
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Steadily drive through the terrain. Apply the
accelerator slowly and avoid excessive
wheel slip. Do not drive your vehicle in deep
sand for an extended period of time. This
could overheat the system. A message
appears in the instrument cluster display.

ACCESSING THE FRONT TOWING
POINT WARNING:
Using recovery hooks is
dangerous and should only be done by a

recovery safety practices. Improper use of
recovery hooks may cause hook failure or
separation from the vehicle and could
result in serious injury or death. WARNING:
Slowly remove the slack
from the recovery strap prior to pulling.

together with a clevis pin. These heavy
metal objects could become projectiles if
the strap breaks and can cause serious

and minimum marks, the oil level is
acceptable. Do not add oil.
6. If the oil level is at the minimum mark, immediately add oil.
7. Reinstall the dipstick. Make sure it is fully
seated.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km). ADDING ENGINE OIL WARNING:
Do not remove the filler
cap when the engine is running. WARNING:
Do not add engine oil
when the engine is hot. Failure to follow
this instruction could result in personal

CHECKING THE COOLANT
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 528). Note:
Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between
-29°F (-34°C) and -35°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING:
Keep your hands and
clothing clear of the cooling fan.
