Driving on flooded roads

!
Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic
components in the engine or the automatic
transmission. Water can also be drawn in
by the engine's air suction nozzles and this
can cause engine damage.
i
Vehicles with the AIRMATIC package:
Set the raised level before driving through
standing water.
Off-road fording
Steel-spring vehicles
Vehicles with the AIRMATIC
package
Raised level
Establish how deep the water is and the
R
characteristics of the body of water before
fording.
Vehicles with the AIRMATIC package:
R
Select the highest possible vehicle level.
Restrict the shift range to 1 or 2.
R
Avoid high engine speeds.
R
Enter and exit the water at a flat place and
R
at a steady walking pace.
!
Under no circumstances should you
accelerate before entering the water. The
bow wave could cause water to enter and
damage the engine and other assemblies.
Drive slowly and at an even speed through
R
the water.
Do not stop.
R
!
Do not open any of the vehicle's doors
while fording. Otherwise, water could get
into the vehicle interior and damage the
vehicle's electronics and interior
equipment.
Water offers a high degree of resistance,
R
and the ground is slippery and in some
cases unstable. Therefore, it is difficult and
dangerous to pull away in the water.
Ensure that a bow wave does not form as
R
you drive.
Clean any mud from the tire tread after
R
fording.
Apply the brakes to dry them after fording.
