•If driving in desert conditions, it is advised that you always drive with
your headlights on to help other drivers more easily see you.
•While driving in desert conditions, the midpoint of the day is the most
difficult time to see many of the small ridges and dips due to flat
shadows from the sun being at its highest point. Extreme care should
be taken at these times to not inadvertently run into these obstacles.
•It is highly encouraged that you switch to off-road mode and perform
an AdvanceTrac single press to ensure improved off-road braking
performance under these conditions. Be sure to disengage the off-road
mode and switch back to AdvanceTrac key-on mode before performing
any street driving. Please see the Off-road mode section of this
supplement for more details.
AFTER OFF-ROAD DRIVING
It is important to complete a full vehicle inspection after off-road driving.
Some items to check include:
•Ensure that tires are inflated to proper tire pressure as indicated on
the tire placard.
•Check the wheels and undercarriage for built up mud or debris which
can cause vehicle vibration.
•Ensure that the grille and radiator are clear of any obstructions that
may affect cooling.
•Ensure that the brakes are in proper working order and free of any
mud, stones etc., which can become trapped around the brake rotor,
backing plate and caliper.
•Check that the air filter is clean and dry.
•Inspect for torn or punctured boots on ball joints, half shafts, steering
gears.
•Inspect exhaust system for damage or looseness.
•Inspect undercarriage fasteners. If any are loose or damaged, tighten
or replace ensuring that the proper torque specification is used.
•Inspect the tires for any cuts in the tread or sidewall area. Also
inspect the sidewall for any bulge indicating damage to the tire.
•Inspect the wheels for dents, cracks, or other damage.
