Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability could be
limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal when slowly moving.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can lose
traction in slick mud. As when you are driving
over sand, apply the accelerator slowly and
avoid spinning your wheels. If the vehicle
does slide, steer in the direction of the slide
until you regain control of the vehicle.
If the transmission, transfer case or front axle
are submerged in water, their fluids should
be checked and changed, if necessary.
If the front or rear axle is submerged in water,
the axle lubricant should be replaced.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.
Note:
Driving through deep water could
damage the vehicle.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back to a safe location. Apply just enough power to the wheels to
climb the hill. Too much power causes the
tires to slip, spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral. Disengage overdrive
or move the transmission selector lever to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer your vehicle.
If your vehicle has anti-lock brakes, apply the
brakes steadily. Do not pump the brakes.

Precautions
•
Do not work on a hot engine.
• Make sure that nothing gets caught in
moving parts.
• Do not work on a vehicle with the engine
running in an enclosed space, unless you
are sure you have enough ventilation.
• Keep all open flames and other burning
material (such as cigarettes) away from
the battery and all fuel related parts.
Working with the Engine Off
1. Set the parking brake and shift the transmission to park (P).
2. Switch off the engine.
3. Block the wheels.
Working with the Engine On WARNING: To reduce the risk of
vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it
while the engine is running. 1. Set the parking brake and shift the
transmission to park (P).
2. Block the wheels.
OPENING AND CLOSING THE
HOOD
1. Inside the vehicle, pull the hood release handle located under the left-hand side
of the instrument panel. 377

ENGINE OIL DIPSTICK MINA
MAXB ENGINE OIL CHECK
To check the engine oil level consistently
and accurately, do the following:
1.
Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes
for the oil to drain into the oil pan.
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.
5. Open the hood.
See Opening and
Closing the Hood (page 377). 6. Remove the dipstick and wipe it with a
clean, lint-free cloth.
See Under Hood
Overview (page 379).
7. Reinstall the dipstick and remove it again
to check the oil level.
See Engine Oil
Dipstick (page 380).
8. Make sure that the oil level is between the maximum and minimum marks. If the
oil level is at the minimum mark, add oil
immediately.
See Capacities and
Specifications (page 440).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.

2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 539).
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
