•
Do not rest your foot on the brake pedal
while driving.

• Avoid driving with the wheels out of

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle. Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the wheel hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the
steering power assist works.
FLOOR MATS WARNING:
Use a floor mat designed
to fit the footwell of your vehicle that does
not obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
Pedals that cannot move
freely can cause loss of vehicle control and
increase the risk of serious personal injury.

4. Replace the air filter housing cover and
secure all the clamps. Be careful not to
crimp the filter element edges between
the air filter housing and cover and
ensure that you properly align the tabs
on the edge into the slots. ENGINE COOLANT CHECK WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system is
under pressure. Steam and hot liquid can
come out forcefully when you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
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 539).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
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.
